Donna has a $300 loan through the bank she is charged a simple rate The total interest she paid on the loan was $63 As a percent

klasskru [66]

The annual interest rate is 21%

<h3>How to determine the annual interest rate?</h3>

The given parameters are

Loan Amount, P = $300

Interest, I = $63

Number of years, T = 1

The annual interest rate is calculated as

I = PRT

Substitute the known values in the above equation

63 = 300 * R * 1

Evaluate the product

300R = 63

Divide through by 300

R = 21%

Hence, the annual interest rate is 21%

Need Help with the composition of two rational functions. screenshot is below

igomit [66]

We just have to write one function inside the other:

$(f\circ g)(x) = f(g(x))\\\\(f\circ g)(x) = f\left(\dfrac{13}{x+3}\right)\\\\(f\circ g)(x) = \dfrac{2}{\left(\dfrac{13}{x+3}\right)+3}\\\\(f\circ g)(x) = \dfrac{2}{~~\dfrac{13+3(x+3)}{x+3}~~}\\\\(f\circ g)(x) = \dfrac{2(x+3)}{13+3(x+3)}\\\\\boxed{(f\circ g)(x) = \dfrac{2x+6}{3x+22}}$

Since we have a fraction with x in the denominator, we have to remove from the domain the value of that makes null the denominator. Thus,

$3x+22\neq0\Longrightarrow 3x\neq22\Longrightarrow x\neq \dfrac{22}{3}$

Furthermore, we also have to remove the value of x that annuls the denominator of g(x), because that's the first function that we use. So:

$x+3\neq0\Longrightarrow x\neq-3$

Hence, the domain is:

$D((f\circ g)(x)) = \left]-\infty,-3\right[\cup \left]-3,\dfrac{22}{3}\right[\cup\left]\dfrac{22}{3},\infty\right[$

You are trying to locate a stolen car using a helicopter. The helicopter costs $250 per hour to rent. The number of hours to fin

fiasKO [112]

Answer:

B. $1750

Step-by-step explanation:

The mean of the discrete uniform distribution is given by:

$M = \frac{a+b}{2}$

In this problem, we have that $a = 3, b = 11$ .

The expected time to find the car is:

$M = \frac{3+11}{2} = 7$

7 hours are expected to find the car.

The helicopter costs $250 per hour to rent.

7*$250 = $1750

So the correct answer is:

B. $1750

Three numbers are in the ratio 4 :5 :6 .If the sum of the largest and smallest

posledela

Answer:

44, 55 and 66.

Step-by-step explanation:

I think you mean the sum of the SECOND and 55. It makes no sense otherwise, if the numbers are integers.

The 3 numbers can be written as 4x, 5x and 6x . So we have the equation:

4x + 6x = 5x + 55

5x = 55

x = 11

So the numbers are 44, 55 and 66.
