Gala2k [10]

Answer:

The Answer is C.

Step-by-step explanation:

There is only one number before the decimal point, 6. 6 ones, so we already cross out A and D as incorrect. Now we have B and C. There is only two numbers after the decimal point. The first number after the point is in the tenths place. So, B is the correct answer.

Make me brainlyest if correct, you're welcome!

The height of a soccer ball is kicked from the ground can be approximately by the function.
stira [4]

Answer:

1 second

Step-by-step explanation:

y = -16x² + 32x

y = -16(x² - 2x)

y = -16(x² - 2(x)(1) + 1² - 1²)

y = -16(x - 1)² + 16

Max height is when (x-1) = 0

So x = 1

Anyone know how to expand 5p(p-3)
Katyanochek1 [597]
I believe what your asking is just multiplying it together so 5p(p-3) would be 5p2-15p. the p2 is p squared or a little 2 on top of the p. Hope I helped!
