Answer:

Step-by-step explanation:

This is most easily solved with calculus, believe it or not. It is way more direct and to the point, with a whole lot less math!

The position function is given. The velocity function is the first derivative of the position, so if we find the velocity function and set it equal to 0, we can solve for the amount of time it takes for the rocket to reach its max height. Remember from physics that at the top of a parabolic path, the velocity is 0.

If:

s(t)=-16t^2+112t+360, then the velocity function, the first derivative is:

v(t) = -32t + 112 and solve for t:

-112 = -32t so

t = 3.5 seconds. Now we know how long it takes to get to the max height, we just need to find out what the max height is.

Go back to the position function and sub in 3.5 for t to tell us that position of the rocket at 3.5 seconds, which translates to the max height:

s(3.5)=-16(3.5)^2+112(3.5)+360 and

s(3.5) = 206 feet. I imagine that your answer, if you had to choose one from the list, would be 200 feet, rounded a lot.

Harding and Jack found that 8 percent of their number was 72. What was their number?
Aneli [31]
I do believe that the answer is 900. 
Steps:
I first set up a proportion, with 8/100 and 72/x (x being the number we are trying to find) 
As I was taught, you multiply 100 by 72, which equals 7,200.
Then, I divided 7,200 by 8, which gave me 900.
This is what the proportion process should have looked like:
8/100    72/x
7,200/8
x=900
I hope this helps!

ElenaW [278]

Answer:

6 pounds of ground beef cost $15.

Step-by-step explanation:

\frac{6}{10} :\frac{y}{25}

10 × y = 6 × 25

10y = 150

10y ÷ 10 = 150 ÷ 10

y = 15
