Answer:  

The correct option is A. 5 miles per hour per second

Step-by-step explanation:

Brooklyn's car is stopped at a red light.

So, when the car stops the speed of the car = 0 miles/ hour

When the light changes, the car accelerates to 75 miles per hour in 15 seconds

And we need to find the approximate rate of change in the miles per hour that Brooklyn's car accelerated

⇒ The approximate rate of change in the miles per hour that Brooklyn's car accelerated is given by :

\frac{75}{15}\text{ miles per hour in 1 second}\\\\\implies 5\text{ miles per hour in 1 second}

Therefore, The correct option is A. 5 miles per hour per second

Does any one know the answers to a and b?
balu736 [363]

Your calculator should give you the answer to both.

3^3 = 3 * 3 * 3 = 27

∛(125) = ∛(5 * 5 * 5) = Three equal factors under a cube root sign give 1 factor on the left of the cube root sign. The other 2 are discarded.

∛(5 * 5 * 5) = 5∛1 = 5

Find the measure of angle C and angle D. show your work.​
Georgia [21]

Answer:C=40 degrees D=76 degrees

Step-by-step explanation:

Because of a theorem angle c and d equal angle DEF

so here is our equation:4y+(7y+6)=116

Open the parentheses

4y+7y+6=116

-6 on both sides

4y+7y=110

11y=110

Divide both sides by 11

y=10

Now we have to substitute

C=4y=4(10)=40

D=7y+6=7(10)+6=70+6=76
