If someone can answer this, you are BEYOND SMARTT!!! But tell me how to do it too!!!!

Look at all the choices

we know that at t = 0, the height of the rock is 16

choices H and I do not have a value of 16 at t = 0.

H: h(0) = -5.2(0)² + 24(0) - 12 = -12
I: h(0) = -4.2(0)² + 26(0) - 20 = -20

so we are left with F and G

if we take choice F and plug in t = 1
h(1) = -4.7(1)² - 25(1) + 16 = -13.7
if we take choice G and plug in t = 1
h(1) = -4.7(1)² + 25(1) + 16 = 36.3

only choice G works for us since it has 36.3 at t = 1

you could have also put these points in a graphing calculator and then use the quadratic regression feature to get an equation that will model this data

If you can mow 1000 square feet per minute, how long to mow a circle with diameter of 800 feet?
maria [59]

Answer:

You can calculate the area of the circle

We know the formula is: \pi*r^2

And if diammeter is 800, then the radio is a half: 400

We replace:

\pi*r^2 --> \pi * 400^2 \approx 502654.8  feet

So now we can divide:

502654/1000 = 502,654 minutes
