I have no idea if im just dumb or what but wouldn't that just be 14 feet?
it asked how far above the ground it would have to touch but it also says that it is 14 feet long sooooo......?
Imagine a 'U' shape
sides are x legnth
base is b legnth
2x+b=25
area is height times base=xb
xb=50
2x+b=25
solve
minus 2x both sides
b=25-2x
sub for b
x(25-2x)=50
25x-2x^2=50
times -1 both sides
2x^2-25x=-50
add 50 both sides
2x^2-25x+50=0
use quadratic formula or something
x=2.5 or 10
A is the answer
Answer: D
Step-by-step explanation:
The slope, 45, would be the amount he charges per hour; the y-intercept, 60, would be the fee he gets paid just for showing up.
Since 45 is multiplied by t, the amount of time, this shows us it is the cost per hour. Since that is the slope, the y-intercept must be 60. We know that y-intercepts are where the data intersects the y-axis; we also know they have an x (t, in this case) coordinate of 0. This means 0 hours have passed, which means it is an up front fee.
