Answer:
Brandi's velocity at the bottom of the hill is 0 ft / s
Step-by-step explanation:
Given:
Height of the bunny hill = 200
speed is given by 
To find:
Brandi's velocity at the bottom of the hill = ?
Solution:
At the bottom of the hill , the height is zero
Thus the speed of Brandi at height h = 0
First, find the area of the large rectangle (25*18=450) then find the area of the small square (7.5^2=56.25) finally subtract the small square from the large rectangle
After 45 minutes you will have painted 4*45=180 square feet.
so the total number of painted area, y, is:
y=180+x*(3+4) after the 45 minutes
where x is the number of minutes AFTER THE 45 minutes:
if y is 1000 then
1000=180+x*7
820=x*7
x=117.14
so 117 minutes, or one hour and 57 minutes.
Parallel means that it has the same gradient but a different Y intercept.
we know it will be:
y=2x+c but we need to know C. what we can do is substitute in the point it needs to go through.
y=2x+c
5=(1×2)+c
5=2+c
3=c
so the equation is:
y=2x+3
