Answer:

In mathematics, an inverse function (or anti-function) is a function that "reverses" another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa, i.e., f(x) = y if and only if g(y) = x.

How to solve this question

Direct variation can be written as a proportion. Therefore, we can write:

\frac{8}{4}= \frac{y}{5}
Cross multiply to get:
4y=40
Divide by 4 on both sides to get that y=10.

I don’t understand how to do this without plugging in numbers or using calculus. Please help. I’m studying for the SAT and I onl
Svetllana [295]

Step-by-step explanation:

Recall that for a quadratic equation y = ax² + bx + c in the X-Y plane, the x-location of the vertex (i.e maximum or minimum point) is given by

x @vertex = -b/2a

in this case your quadratic equation is

h = 4 + 20t - 5t²   (rearranging in the form y = ax² + bx + c )

h = - 5t² + 20t + 4

hence a= -5, b = 20 and c = 4

applying the formula for vertex

t @ vertex = -b  /2a = -(20) / (2)(-5) = -20/-10 = 2

therefore t = 2
