Answer:
45
Step-by-step explanation:
You need to find the vertex of the function.
The easiest way to do this is to graph it on a calculator like desmos.
but you can find the line of symmetry with this equation. x=-b/2a
x=-112/2(-16)
x= 3.5
Then plug that into the equation.
-16(3.5)^2+112(3.5)+30
226
226ft is the maximum height.
Answer:
4:5 is the ratio in it simplest form
Based from the given
data, the expected number of cars sold in one week is B. 1.5.
The equation to solve
the problem would be like this. 0*1/8 + 1*3/8 + 2*3/8 + 3*1/8 = 3/2
which when simplified is 1.5.
