The correct answer is a. -∞, f(x) → -∞; x → ∞, f(x) → ∞b. -∞, f(x) → -∞; x → ∞, f(x) → ∞c. -∞, f(x) → -∞; x → ∞, f(x) → ∞d. -∞, f(x) → -∞; x → ∞, f(x) → -∞

For the polynomial function f(x) = 6x^5 + 7x^2 + 7x + 9, the leading coefficient is 6 (the coefficient of the highest-degree term). The degree of the polynomial is 5, which is odd.

According to the Leading Coefficient Test, when the degree of the polynomial is odd and the leading coefficient is positive (in this case, positive 6), the end behavior of the graph is as follows:

- As x approaches negative infinity (-∞), f(x) approaches negative infinity (-∞).

- As x approaches positive infinity (∞), f(x) approaches positive infinity (∞).

For the polynomial function f(x) = 61x^11 + 7x^2 + 2x + 8, the leading coefficient is 61 (the coefficient of the highest-degree term). The degree of the polynomial is 11, which is odd.

Using the Leading Coefficient Test, we can determine the end behavior:

- As x approaches negative infinity (-∞), f(x) approaches negative infinity (-∞) since the leading coefficient is positive.

- As x approaches positive infinity (∞), f(x) also approaches positive infinity (∞) due to the same reason.

For the polynomial function f(x) = 5x^8 + 3x^2 + 2x + 9, the leading coefficient is 5 (the coefficient of the highest-degree term). The degree of the polynomial is 8, which is even.

Applying the Leading Coefficient Test:

- As x approaches negative infinity (-∞), f(x) approaches positive infinity (∞) because the leading coefficient is positive.

- As x approaches positive infinity (∞), f(x) also approaches positive infinity (∞) for the same reason.

For the polynomial function f(x) = -2x^8 + 6x^2 + 4x + 9, the leading coefficient is -2 (the coefficient of the highest-degree term). The degree of the polynomial is 8, which is even.

Using the Leading Coefficient Test:

- As x approaches negative infinity (-∞), f(x) approaches negative infinity (-∞) since the leading coefficient is negative.

- As x approaches positive infinity (∞), f(x) approaches negative infinity (-∞) due to the same reason.

The difference between the cash price and the initial deposit in hire purchase is known as \(_\( \text{Principal} \)_\).

In hire purchase transactions, buyers can acquire goods by making an initial down payment and paying the remaining amount in installments. The difference between the total cost of the item and the initial deposit is a crucial concept known as the \(_\( \text{Principal} \)_\) in mathematical terms. Let's explore this in detail.

In the context of hire purchase, the total cost of the item is often referred to as the cash price. It represents the actual value of the item without considering any interest or finance charges. On the other hand, the initial deposit, also called the down payment, is the amount paid upfront by the buyer to secure the item.

Now, let's introduce some variables to help us understand this concept mathematically:

- Let CP be the cash price of the item.

- Let D be the initial deposit made by the buyer.

The difference between the cash price and the initial deposit is given by:

\(\[ \text{Principal} = CP - D \]\)

The Principal is the amount that remains to be paid off in installments, and it serves as the basis for calculating the subsequent monthly or periodic payments in a hire purchase agreement.

The Principal is critical because it determines the total amount the buyer will end up paying for the item. It also affects the duration of the hire purchase agreement, as the buyer's installments are typically spread over a specific number of months or years.

Answer:

\(P(x = 0) = 0.061\)

Step-by-step explanation:

Given

\(Average = 2.8\)

Required

Determine the probability that no car will arrive.

Since it is a Poisson distribution, the required probability is:

\(P(x) = \frac{e^{-m}m^x}{x!}\)

Where

\(m = average = 2.8\)

In this case;

\(x = 0\)

So:

\(P(x) = \frac{e^{-m}m^x}{x!}\)

\(P(x = 0) = \frac{e^{-2.8}2.8^0}{0!}\)

\(P(x = 0) = \frac{e^{-2.8}*1}{1}\)

\(P(x = 0) = e^{-2.8}\)

\(P(x = 0) = 0.06081006262\)

Option C is the table of values representing a proportional relationship in the context of this problem.

A proportional relationship is a relationship in which a constant ratio between the output variable and the input variable is present.

The equation that defines the proportional relationship is a linear function with slope k and intercept zero given as follows:

y = kx.

The slope k is the constant of proportionality, representing the increase or decrease in the output variable y when the constant variable x is increased by one.

For item c, we have that the output is equals to the input, hence the proportional relationship is given as follows:

y = x.

The requried, probability that both the first digit in the last digit of the three-digit number is even numbers is 20%.

To count the number of three-digit numbers with distinct digits that can be formed using the digits 1, 2, 3, 5, 8, and 9, we can use the permutation formula:

P(n, r) = n! / (n-r)!

In this case, we have n = 6 (since we have 6 digits to choose from) and r = 3 (since we want to form three-digit numbers). Using the formula, we get:

P(6, 3) = 120

We can choose the first digit in two ways (2 or 8), and we can choose the last digit in three ways (2, 8, or 6). For the middle digit, we have four digits left to choose from (1, 3, 5, or 9), since we cannot repeat digits. Therefore, the number of three-digit numbers with distinct digits that have an even first and last digit is:

2 x 4 x 3 = 24

The total number of three-digit numbers with distinct digits is 120, so the probability that a randomly chosen three-digit number with distinct digits has an even first and last digit is:

24/120 = 0.2 or 20%

Answer:

b. 5 meters

Step-by-step explanation:

1 meter = 1000 millimeters

5 meter = 5000 millimeters

Which is longer 5 meters or 400 millimeters?

5000 > 400

So, the answer is b. 5 meters.

Answer:

As this is a quartic equation, we should expect four roots (although some may end being repeated). Notice also that the equation is symmetrical, which suggests that there might be an element of symmetry in the answer.

First, as this equation is a quadratic in terms of z2 , we can use our formula for finding the roots of a quadratic equation to give the value(s) of z2 . [If you have a problem seeing this, use the substitution y=z2 , and you get a quadratic in y .]

z2=−4±42−4×1×16√2×1=−4±16−64√2

=−4±−48√2=−2±12−−√i=−2±23–√i

=4(−12±3√2)i

=4(cos(2kπ3)+isin(2kπ3)) , where k∈1,2

=4e2kiπ3

As this is the value of z2 , whereas we want z , we need to take the square roots of both sides

z=4–√ekiπ3+nπ , where n∈0,1

=2e(k+3n)iπ3

=2cis((k+3n)iπ3)

As we have two values of k and two values of n , this gives us four solutions.

Writing these angles in terms of degrees, we have: 60, 120, 240 and 300

Evaluating, we end up with the four solutions

z=1±3–√i∪z=−1±3–√i

You can substitute z^2 = x,

Then you get x^2+4x+16=0

Step-by-step explanation:

z=1±3–√i∪z=−1±3–√i

You can substitute z^2 = x,

Then you get x^2+4x+16=0

Then you can use classical x1,2 = (-b +- √[b^2–4ac])/2a

X1,2=(-4+-√[16–16*4])/2

After you solve that you substitute back z^2 = x

Hi! The slope is  -3/2

Y intercept  2.5

(0,2.5)

Step-by-step explanation:

I hope this helps!

Answer:

The slope is \(\frac{-3}{2}\)

The y - intercept is 2 1/2

The y-intercept point is (0, 2 1/2)

Step-by-step explanation:

If you start at the point on the left to get to the lower point on the right, you need to go down 3 units and to the right 2 units.  This is the slope.  Going down represents a negative number and going right represents a positive number.  The slope is \(\frac{-3}{2}\)

The y -intercpet is where the graph is cross the y axis.  It looks like it is crossing between 2 and 3.  So, 2 1/2 is a good estimate.  Actually, I did calculate the y-intercept and it is in fact 2 1/2.

The point of the y-intercept is when x = 0
