H = -16t^2 + vt +k The equation above gives the height h, in feet, of a ball t
seconds after it is thrown straight up with an initial speed of v
feet per second from a height of k feet. What is an equation that
shows v in terms of h, t, and k?

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

the correct answers i think are b. and d.

give me brainliest if it is correct!

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .

i would love   to but there is no graph shown

i am so sorry
