Answer:
20
Step-by-step explanation:
the inverse of
y=1/2x + 10
is
x=1/2y+10
from here you just solve for y
x-10 = 1/2y
2(x-10) = y
2x-20 = y
t = time
Multiply the acceleration by time and add to the height:
The equation becomes H(t) = -16 * t^2 + 90
set h(t) to 0
0 = -16*t^ +90
Subtract 90 from both sides:
-90 = -16*t^2
divide both sides by -16:
t^2 = -90 / -16
t^2 = 5.625
t = √5.625
t = 2.37 seconds, round to 2.4 seconds.
Ok so if the parenth function is y=x^2
to move it up c units, add c to whole function
to move it right c units, minus c from every x
looks like we have
y=(x-6)^2-5
add -5 to whole funciton
minus 6 from every x
means that it moved 5 units down and 6 to the right from original function if parenth is y=x^2

Isn't it simple because all other numbers are less than 4?
