Question

last question.. promise :)
A ball is tossed from a window that is 10 feet off the ground. The height, h (in feet), of the ball at any time, t (in seconds), is given by the equation h = - 16t^2 + 12x + 10. What is the maximum height (in feet) that the ball will reach? Type the number only in the box, do not put measurement units.

Answer 1

guess what? it is once again \(-\frac{b}{2a}\) this time
\[-\frac{12}{2\times (-16)}\]

Answer 2

your fraction reduces to \(\frac{3}{8}\)

Answer 3

do i solve after that?

Answer 4

replace \(x\) by \(\frac{3}{8}\)

Answer 5

don't you differentiate it for the maximum?

Answer 6

nope

Answer 7

our miss brooks is not taking calc, she is taking algebra

Answer 8

i thought u squared the denominator?

Answer 9

nope

Answer 10

\[-\frac{b}{2a}\] there is no square

Answer 11

so for max i just put 3/8

Answer 12

replace \(t\) by \(\frac{3}{8}\) get \(\frac{49}{4}\) as your answer

Answer 13

12.25?

Answer 14

\(\frac{3}{8}\)is not the max, it is the number that you use to find the max

Answer 15

yes, 12.25

Answer 16

yayyy thanks sooo much :)

Answer 17

you done?

Answer 18

yes i just needed the max
