A toy rocket is launched vertically upward from ground level and it's height (h) after t seconds is given by the equation h(t) = -16t2 + 128t. How many seconds will it take for the rocket to hit its maximum height? How many seconds will it take the rocket to return to the ground?

hey i’m new i won’t be answering any questions now bye peeps see you next time

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
