The function y=−16x2+v0x models lindy's height in feet above a trampoline x seconds after she jumps straight up. in the equation of the function, v0 is her initial velocity in feet per second. lindy lands back on the trampoline 1 second after she jumps.

The initial velocity of Lindy was 16 ft/s

Step-by-step explanation:

Given:

It is function models of Lindy's Height in feet above a trampoline x seconds after she jumps straight up.

In the equation of the function

is initial velocity in feet per second.

We need to find the initial speed of Lindy

If She lands back on the trampoline after 1 seconds.

It means y must be zero because she lands back on trampoline.

At x=1, y must be 0

Hence, The initial velocity of Lindy was 16 ft/s

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.
