find the x-intercepts of y= x^2+4x+8 using the quadratic formula.

A polynomial can have as many real zeros as its degree, hence one with three degrees can have as many as three zeros.

The roots of an equation are the solution of that equation since an equation consists of hidden values of the variable to determine them by different processes and then the resultant is called roots.

A polynomial with n degrees can have as many variables as n in total.

For example, a quadratic equation ax² + bx + c = 0 is a two-degree equation so it has a maximum of two roots or zeros.

A polynomial with the given degree structure will have exactly 3 roots because it has 3 degrees.

Hence "The maximum number of real zeros in a polynomial will be same as its degree thus 3 degrees will have 3 zeros".

Answer:

The answer is below

Step-by-step explanation:

A function show the relationship between an independent variable and a dependent variable. The independent variable (input) does not depend on other variables while the dependent variable (output) depend on other variables.

In this question, amount of water in tank is dependent variable and the time taken is the independent variable. Let y represent amount of water in tank and x represent the time it has been draining. Therefore:

a) This can be represented by the equation:

y = 450 -  20x

At 7 minutes (x = 7)

y = 450 - 20(7)

y = 310 gallons

b) For 200 gallons (y = 200), the time taken is:

200 = 450 - 20x

200 - 450 = -20x

-20x = -250

x = -250/-20

x = 12.5 minutes

c) y = 450 - 20x

d) The graph was plotted using geogebra onling graphing calculator.

e) When the tank is empty, y = 0, hence

0 = 450 - 20x

20x = 450

x = 450 / 20

x = 22.5 minutes

The equation that demonstrates the relationship between the gallons of water in the tank and minutes the tank has been draining is 450 - 20X = Gallons drained. After 7 minutes there will be 310 gallons of water in the tank. It will take 12.5 minutes for the tank to have 200 gallons. It will take 22.5 minutes until the tank is empty.

Since a 450-gallon tank full of water is draining at a rate of 20 gallons per minute, to determine how many gallons will be in the tank after 7 minutes; how long will it take for the tank to have 200 gallons; the relationship between the gallons of water in the tank and minutes the tank has been draining; and how long will it take until the tank is empty, the following calculations must be performed:

Step-by-step explanation:

The yards of ribbon purchased by Susan using amount on the debit card is equal to 32 yards.

Amount on prepaid debit card  = $20

Price of the ribbon  = 16 cents per yard

Amount left on the card after purchasing ribbon = $14.88  

Amount used to purchase ribbon

= Amount on initial amount debit card  - Amount left after purchasing ribbon

= $20.00 - $14.88 =$5.12

So Susan spent $5.12 on the ribbon.

Now ,use the price per yard to figure out how many yards she bought,

= Amount spent to buy ribbon / price of the ribbon per yard

= $5.12 ÷ $0.16 per yard

= 32 yards

Therefore, Susan bought 32 yards of ribbon with her prepaid debit card.

The plot of y(t) will show how the mass oscillates with time, starting from the equilibrium position and gradually coming to rest due to the damping effect of the friction.

The given equation represents the motion of a mass connected to a spring with viscous friction. To plot the displacement, y(t), we need to solve the differential equation. With initial conditions y(0) = 0, we can find the solution using the Laplace transform. After solving the equation, we can plot y(t) for t < 0 and t ≥ 0 separately. For t < 0, the applied force, f(t), is zero, so the mass will not experience any external force and will remain at rest. For t ≥ 0, the applied force is 10, and the mass will respond to this force and undergo oscillatory motion around the equilibrium position.

To solve the given differential equation, we can start by finding the characteristic equation by setting the coefficients of y, its derivative, and its second derivative to zero:

s^2 + 18s + 102 = 0.

Solving this quadratic equation gives us the roots s1 = -3 + 3i and s2 = -3 - 3i. These complex roots indicate that the mass will undergo damped oscillations.

Using the Laplace transform, we can solve the differential equation and obtain the expression for Y(s), the Laplace transform of y(t):

(s^2 + 18s + 102)Y(s) = F(s),

where F(s) is the Laplace transform of f(t). Since f(t) = 10 for t ≥ 0, its Laplace transform is F(s) = 10/s.

Solving for Y(s) gives us:

Y(s) = 10 / [(s^2 + 18s + 102)].

To find y(t), we need to inverse Laplace transform Y(s). Using partial fraction decomposition, we can express Y(s) as:

Y(s) = A / (s - s1) + B / (s - s2),

where A and B are constants to be determined. After finding A and B, we can inverse Laplace transform Y(s) to obtain y(t).

With the given initial condition y(0) = 0, we can solve for A and B by setting up equations using the initial value theorem:

A / (s1 - s1) + B / (s1 - s2) = 0,

A / (s2 - s1) + B / (s2 - s2) = 0.

Solving these equations will give us the values of A and B. Finally, we can substitute these values back into the inverse Laplace transform of Y(s) to obtain y(t).

For t < 0, since the applied force f(t) is zero, the mass will not experience any external force. Therefore, y(t) will remain at its initial position, y(0) = 0.

For t ≥ 0, the applied force f(t) is 10, and the mass will respond to this force and undergo oscillatory motion around the equilibrium position. The displacement, y(t), will depend on the properties of the mass, the spring, and the viscous friction. The plot of y(t) will show how the mass oscillates with time, starting from the equilibrium position and gradually coming to rest due to the damping effect of the friction.

If in a survey, 200 college students were asked whether they live on campus and if they own a car, 55% of college students in the survey don't own a car.

To find the percent of college students who don't own a car, we need to add up the number of students who don't own a car and divide it by the total number of students in the survey. In this case, the total number of students in the survey is 200.

From the table, we can see that there are 88 students who live on campus and don't own a car, and 22 students who don't live on campus and don't own a car. So the total number of students who don't own a car is 88 + 22 = 110.

To find the percentage, we divide the number of students who don't own a car by the total number of students in the survey and then multiply by 100 to get the percentage:

Percentage of students who don't own a car = (110/200) x 100% = 55%

Using Theorem 9.11, we can determine the convergence or divergence of the p-series given by:

1 + 1/(8√2) + 1/(8√3) + 1/(8√4) + ...

The general form of this series is:

Σ (1/(8√n))

Comparing this to a p-series, we can see that the exponent p in the denominator is 1/2, as it involves a square root:

Σ (1/n^p) with p = 1/2

According to Theorem 9.11, a p-series converges if p > 1 and diverges if p ≤ 1. In this case, p = 1/2, which is less than or equal to 1. Therefore, this p-series diverges.

Theorem 9.11 states that the p-series 1/n^p converges if p > 1 and diverges if p ≤ 1.

In this case, we have a series of the form 1/√n^p, where n = 1, 2, 3, ... Since the denominator is growing exponentially with n, the terms are decreasing to zero.

To apply the theorem, we need to compare p to 1. Since the series has a square root in the denominator, we can rewrite it as 1/(n^(p/2)√n). Thus, p/2 is the exponent of the series without the square root.

If p/2 > 1, then p > 2, and the series converges by Theorem 9.11. If p/2 ≤ 1, then p ≤ 2, and the series diverges by Theorem 9.11.

So, in this case, p/2 = 1/8, which is less than 1. Thus, p ≤ 2 and the series diverges by Theorem 9.11. Therefore, the answer is "diverges".

The probability that the student's time for the mile will be less than or equal to 7 minutes is `P(y ≤ 7) = P(z ≤ -0.15) ≈ 0.4432`.

A study of 12,000 able-bodied male students at the University of Illinois found that their times for the mile run were approximately normal with a mean of 7.11 minutes and a standard deviation of 0.74 minutes. We need to choose a student at random from this group and call his time for the mile y.

The random variable y follows a normal distribution with mean `mu` = 7.11 and standard deviation `sigma` = 0.74 minutes. If a student is chosen randomly, the probability that his time for the mile will be less than or equal to 7 minutes is as follows: `P(y ≤ 7)`.

Let us calculate the z-score using the formula z = `(y - mu) / sigma`. Here, `y` = 7, `mu` = 7.11, and `sigma` = 0.74. `z = (7 - 7.11) / 0.74 ≈ -0.15`. Therefore, P(y ≤ 7) can be calculated as follows: `P(y ≤ 7) = P(z ≤ -0.15)`. We can find the probability of z being less than or equal to -0.15 using the standard normal distribution table or calculator. Using the standard normal distribution table, we get `P(z ≤ -0.15) = 0.4432`.

The statement "the inverse of a cubic function is also a function" is sometimes true.

The inverse of a function exists only when the function is one-to-one, meaning that each input value (x) corresponds to a unique output value (y). For a cubic function, it is not always one-to-one.

If a cubic function is strictly increasing or strictly decreasing over its entire domain, then its inverse will be a function. In this case, the statement is true.

However, if a cubic function has regions where it is not strictly increasing or decreasing, it will fail the horizontal line test, and its inverse will not be a function. In this case, the statement is false.

Therefore, whether the statement is true or false depends on the specific cubic function being considered.

dp[i] = dp[i-1] + dp[i-2] + ... + dp[i-k]

This is because we can add a weight of j (1 ≤ j ≤ k) to a box that weighs i-j, to obtain a box that weighs i. We can start with dp[0] = 1 (the empty box weighs 0) and dp[i] = 0 for i < 0. Finally, the answer is dp[total].

Here is the Python code to implement the above approach:

def count_ways(total, k):

There are 57 different ways a person can vote for the regional judges.

To determine the number of different ways a person can vote for regional judges, we can use the concept of combinations. In this case, we want to find the number of ways to choose a certain number of judges from a total of 6 candidates.

Since voters can choose to vote for 0, 1, 2, 3, or 4 judges, we need to find the sum of all the possible combinations for each number of judges.

For choosing 0 judges, there is only one possible combination (choosing none).

For choosing 1 judge, there are 6 possible combinations (choosing one out of the six candidates).

For choosing 2 judges, there are \(C(6, 2) = 15\) possible combinations. This is calculated using the combination formula, which  \(C(n, r)\)represents the number of combinations of choosing r items from a set of n items.

For choosing 3 judges, there are \(C(6, 3) = 20\) possible combinations.

For choosing 4 judges, there are \(C(6, 4) = 15\) possible combinations.

To find the total number of different ways a person can vote, we sum up the number of combinations for each scenario:

\(1 + 6 + 15 + 20 + 15 = 57\)

1.  The simultaneous solution of the given equations is X=12/5 and Y=4/5

2.1)The combination of X and Y that will yield the optimum for this problem is X=0 and Y=3.3.

2)The combination of X and Y that will provide a minimum for this problem is X=3 and Y=0.

To find the simultaneous solution of the given equations 4X+3Y=12 and 2X+4Y=8, we can use the method of elimination, also known as the addition method. Multiplying the second equation by 2, we get 4X+8Y=16.

Now, we can subtract the first equation from the second equation: 4X+8Y - (4X+3Y) = 8Y - 3Y = 5Y and 16 - 12 = 4. Thus, 5Y=4 or Y = 4/5.

Substituting this value of Y in any of the two equations, we can find the value of X. Let's substitute this value of Y in the first equation: 4X+3(4/5)=12 or 4X

= 12 - (12/5)

= (60-12)/5

= 48/5.

Thus, X = 12/5. Hence, the simultaneous solution of the given equations is X=12/5 and Y=4/5.2. To find the optimal values of X and Y that will maximize the objective function Z=$10X+$50Y, we need to use the method of linear programming.

First, let's plot the feasible region defined by the given constraints:We can see that the feasible region is bounded by the lines 3X+4Y=12, 2X+5Y=10, X=0, and Y=0.

To find the optimal solution, we need to evaluate the objective function at each of the corner points of the feasible region, and choose the one that gives the maximum value.

Let's denote the corner points as A, B, C, and D, as shown above. The coordinates of these points are: A=(0,3), B=(2,1), C=(5/2,0), and D=(0,0). Now, let's evaluate the objective function Z=$10X+$50Y at each of these points:

Z(A)=$10(0)+$50(3)

=$150, Z(B)

=$10(2)+$50(1)

=$70, Z(C)

=$10(5/2)+$50(0)

=$25, Z(D)

=$10(0)+$50(0)=0.

Thus, we can see that the maximum value of Z is obtained at point A, where X=0 and Y=3. Therefore, the combination of X and Y that will yield the optimum for this problem is X=0 and Y=3.3.

To find the combination of X and Y that will provide a minimum for the problem Minimize Z=X+5Y subject to: 4X+3Y≥12 and 2X+5Y≥10, we need to use the same method of linear programming as above.

First, let's plot the feasible region defined by the given constraints:We can see that the feasible region is bounded by the lines 4X+3Y=12, 2X+5Y=10, X=0, and Y=0.

To find the optimal solution, we need to evaluate the objective function Z=X+5Y at each of the corner points of the feasible region, and choose the one that gives the minimum value.

Let's denote the corner points as A, B, C, and D, as shown above.

The coordinates of these points are: A=(3,0), B=(5,1), C=(0,4), and D=(0,0).

Now, let's evaluate the objective function Z=X+5Y at each of these points:

Z(A)=3+5(0)=3,

Z(B)=5+5(1)=10,

Z(C)=0+5(4)=20,

Z(D)=0+5(0)=0.

Thus, we can see that the minimum value of Z is obtained at point A, where X=3 and Y=0. Therefore, the combination of X and Y that will provide a minimum for this problem is X=3 and Y=0.

The correct answers are: 1. Total revenue for this consolidation: $750,000.00. 2. Total costs for this consolidation: $201,162.22. 3. Profit/loss on this consolidation: $548,837.78.

To calculate the total revenue, costs, and profit/loss for the consolidation, we need to break down the given information and perform the necessary calculations. Let's go step by step:

1. Calculate the total revenue:

The cargo is charged based on revenue tons, so we need to convert the volume of cargo loaded (30 m³) and the weight (20,000 kg) into revenue tons.

- Volume: 30 m³

To determine the revenue tons, we'll assume the cargo is loaded to its maximum capacity of 40 m³ in a 40-ft standard container. We can calculate the revenue tons using the formula: Revenue Tons = (Volume Loaded / Maximum Volume) * Weight

Revenue Tons = (30 m³ / 40 m³) * 20,000 kg

Revenue Tons = 0.75 * 20,000 kg = 15,000 kg

- Weight: 20,000 kg

Since the weight is already in kilograms, we can directly use this value.

Now, we can calculate the total revenue:

Total Revenue = Revenue Tons * Selling Rate per Revenue Ton

Total Revenue = 15,000 kg * $50.00/kg (assuming the selling rate is $50.00 per revenue ton)

Total Revenue = $750,000.00

Therefore, the total revenue for this consolidation is $750,000.00.

2. Calculate the total costs:

We need to consider the costs of ocean freight, container loading in Mumbai, and Marseille unloading.

- Ocean Freight:

The cost of ocean freight per 40-ft standard container is given as $1,250.00.

Since the cargo loaded is less than the maximum capacity, we'll consider only a fraction of the cost based on the loaded volume:

Ocean Freight Cost = (Volume Loaded / Maximum Volume) * Ocean Freight Cost per Container

Ocean Freight Cost = (30 m³ / 40 m³) * $1,250.00

Ocean Freight Cost = 0.75 * $1,250.00 = $937.50

- Container Loading in Mumbai:

The cost of container loading in Mumbai is given as $10.00 per revenue ton.

Container Loading Cost = Weight * Cost per Revenue Ton

Container Loading Cost = 20,000 kg * $10.00/kg = $200,000.00

- Marseille Unloading:

The cost of Marseille unloading is €10.00 per revenue ton, but we need to convert it to USD using the given exchange rate.

Exchange Rate = €1.00 = $1.06

Marseille Unloading Cost = (Weight / 1,000) * Cost per Revenue Ton * Exchange Rate

Marseille Unloading Cost = (20,000 kg / 1,000) * €10.00/kg * $1.06/€

Marseille Unloading Cost = 20 * €10.00 * $1.06 = €212.00

Converting to USD: €212.00 * $1.06 = $224.72

Now, we can calculate the total costs:

Total Costs = Ocean Freight Cost + Container Loading Cost + Marseille Unloading Cost

Total Costs = $937.50 + $200,000.00 + $224.72

Total Costs = $201,162.22

Therefore, the total costs for this consolidation amount to $201,162.22.

3. Calculate the profit/loss:

Profit/Loss = Total Revenue - Total Costs

Profit/Loss = $750,000.00 - $201,162.22

Profit/Loss = $548,837.78

Therefore, the profit/loss on this consolidation is $548,837.78.

Note: The complete question is:

A freight forwarder has a weekly consolidated service Mumbai - Marseille, with direct costs as follows:

Ocean freight: US $1,250.00/40-ft standard container.

Container loading in Mumbai: US $10.00 per revenue ton.

Marseille unloading: €10.00 per revenue ton.

Exchange rate is = €1.00 US $1.06.

From past experience, the marketing department has determined that they need to load 40 m³ of cargo in a 40-ft standard container to break even and be able to sell to their customers an all-inclusive rate of US $50.00 per revenue ton.

Based on the above shipment details, answer the following scenario: Last week they loaded 30 m³, 20000 kg in their consolidation.

Answer:

A. 0.318 and 0.3444...

Step-by-step explanation:

Rational numbers are numbers that can be expressed as fractions. Rational numbers include finite values and repeating decimals that have a pattern.

Because all of the answer choices include decimals that have no predictable pattern of decimals, A must be correct.

0.318 is rational because it is finite. 0.3444... will continue to add 4 on to the end of the number, meaning it is repeating predictably, and it is rational.
