The amount of money that is invested in the account that yields an 8% interest is $6,050.

The amount of money that is invested in the account that yields a 4% interest is $4,650.

Given these two equations:

x = y + 1400

x - y = 1400 equation 1

0.08x + 0.04y = 670 equation 2

take the following steps to determine the amount of money invested at each interest rate:

Multiply equation 1 by 0.08

0.08x - 0.08y = 112 equation 3

Subtract equation 3 from equation 2

0.12y = 558

Divide both sides by 0.12

y = 558 / 0.12

y = $4,650

x =  $4,650 + 1400

x = $6,050

The answer from part A tells us that the trout population was 10 in the first month after it was introduced.

A. P(0) = 740 / (1 + 73e^-0) = 740 / (1 + 73) = 740 / 74 = 10, so the answer is 10.

B. The answer from part A tells us that the trout population was 10 in the first month after it was introduced.

C. To find the number of trout in the lake after 1 year, we need to find P(12): P(12) = 740 / (1 + 73e^-0.07*12) = 740 / (1 + 73e^-0.84) ≈ 490, so the answer is 490.

D. To find the number of trout in the lake after 10 years, we need to find P(120): P(120) = 740 / (1 + 73e^-0.07*120) = 740 / (1 + 73e^-8.4) ≈ 740, so the answer is 740.

E. lim t→∞ P(t) = 740, so the answer is 740.

F. The answer from part E tells us that as the number of months t approaches infinity, the trout population will approach 740. This means that the trout population will eventually stabilize at 740 if no other factors such as predators, disease, or lack of food affect the population.

Answer:

31 yards

Step-by-step explanation:

Since there are 3ft in 1 yard,

93 ft / 3 ft = 31 yards

Answer:

31 yards

Step-by-step explanation:

1 ft is 1/3 yard

So 93 ft = 93/3

= 31 yards

OR

1 ft is 0.333 yard

93 × 0.333 = 31 yard.

The image of  y = −2x^2 − 20x + 2 after a translation right 4 units and up 2 units is written in:

The graph will be a vertical parabola opening downwards

when the function y = −2x^2 − 20x + 2 translates right 4 units it gives  

y = -2(x - 4)^2 − 20(x - 4) + 2

going up two units

y = -2(x - 4)^2 − 20(x - 4) + 2 + 2

simplifying the equation further gives

y = -2(x - 4)(x - 4) − 20(x - 4) + 4

y = -2(x^2 - 8x + 16) - 20x - 80 + 4

y = -2x^2 + 16x - 20x - 32 - 80 + 4

y = -2x^2 - 4x - 108

completing the square

-2x^2 - 4x - 108 = 0

-2x^2 - 4x = 108

-2x^2 - 4x + (4/4)^2 = 108 -(4/4)^2

-2x^2 - 4x + (1)^2 = 108 - 1

Answer:

a) P(A∩B) = 0.29

b) P1 = 0.1

c) P = 0.35

Step-by-step explanation:

Let's call A the event that the motorist stop at the first signal, and B the event that the motorist stop at the second signal.

From the question we know:

P(A) = 0.39

P(B) = 0.54

P(A∪B) = 0.64

Where P(A∪B) is the probability that he stop in the first, the second or both signals. Additionally, P(A∪B) can be calculated as:

P(A∪B)  = P(A) + P(B) - P(A∩B)

Where P(A∩B) is the probability that he stops at both signals.

So, replacing the values and solving for P(A∩B), we get:

0.64 = 0.39 + 0.54 - P(A∩B)

P(A∩B) = 0.29

Then, the probability P1 that he just stop at the first signal can be calculated as:

P1 = P(A) - P(A∩B) = 0.39 - 0.29 = 0.1

At the same way, the probability P2 that he just stop at the second signal can be calculated as:

P2 = P(B) - P(A∩B) = 0.54 - 0.29 = 0.25

Finally, the probability P that he stops at exactly one signal is:

P = P1 + P2 = 0.1 + 0.25 = 0.35

No,  the slope of a horizontal line y=6 is,  zero not negative.

What is a Slope?

In Mathematics, a slope of a line is the change in y coordinate with respect to the change in x coordinate.

The net change in y-coordinate is represented by Δy and the net change in x-coordinate is represented by Δx.

Hence, the change in y-coordinate with respect to the change in x-coordinate is given by,

m = change in y/change in x = Δy/Δx

Where “m” is the slope of a line.

Generally, the slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says (x1,y1) and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The slope is usually represented by the letter ‘m’.

Slope Formula

If P(x1,y1) and Q(x2,y2) are the two points on a straight line, then the slope formula is given by:

Slope, m = Change in y-coordinates/Change in x-coordinates = Δy/Δx

m = (y2 – y1)/(x2 – x1)

In the given equation of line y=6 .

The line crosses the y-axis at 6, as the line is always at that value. As it is a horizontal line, the slope is zero.

The equation y = 6 means for each and every value of x, y will be equal to 6.

This is the definition of a horizontal line.

By definition, the slope of a horizontal line is m = 0

When x = 0 then y = 6

Therefore, the y-intercept is: (0, 6).

Hence , the the slope of a horizontal line , m = 0.

It took Emily 33.4 minutes to make dinner.

A mixed number is a kind of fraction that also has a proper fraction and a whole number. The number of whole units is represented by the whole number, and the fraction of a unit is represented by the proper fraction.

To solve the problem, we have to convert the mixed number  \(9 \frac{1}{10}\)   to a decimal number:

⇒ \(9 \frac{1}{10} = 9 +\frac{1}{10} = \frac{(9*10)+1}{10}\)

⇒ \(\frac{91}{10}\)  =  9.1

This means that Emily finished making dinner 9.1 minutes sooner than the cake.

To find out how long it took Emily to make dinner, we can subtract 9.1 from the cake baking time:

⇒ 42.5 - 9.1 = 33.4 minutes

Therefore, it took Emily 33.4 minutes to make dinner.

The function f(x) =2x^3 - 8x is an even function.

A function is known to be even function if the function f(x) is equal to f(-x)

Given the function below;

f(x) = 2x^3 - 8x

Determine the function f(-x)

f(-x) = 2(-x)^3 - 8 (-x)

f(-x) = -2x^3 + 8x
f(-x) = -(2x^3 - 8x)

Since f(x) = 2x^3 - 8x, hence;

f(-x) = f(x)

Therefore the function f(x) =2x^3 - 8x is an even function.

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Let, The number of lacrosse sticks be 'x' and the total cost is C(x).

Therefore, The equation representing the context is,

C(x) = 25x + 750.

Step-by-step explanation:

all you have to do is follow the rules of PEMDAS and treat it like a normal equation of order of operations;

The probability that both players show rock in the first round is 1/9 or 0.1111 (rounded to four decimal places).

In rock, paper, scissors there are three possible outcomes for each player: rock, paper, or scissors. Assuming both players choose randomly and independently of each other, each player has a 1/3 chance of showing rock in the first round.

To find the probability that both players show rock in the first round, we can use the multiplication rule of probability for independent events. The multiplication rule states that the probability of the intersection of two independent events is the product of their probabilities.

Therefore, the probability that both players show rock in the first round can be calculated as follows:

P(both show rock) = P(player 1 shows rock) x P(player 2 shows rock) P(both show rock) = 1/3 x 1/3 P(both show rock) = 1/9

So the probability that both players show rock in the first round is 1/9 or approximately 0.111.
