The height, h, in feet, of an object thrown upward from a height of 144 feet is a function of time, t, in seconds. the height can be determined by the function h(t) -16t^2 + 128 + 144. the height of the object at 3 seconds is 384 feet. why?

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
