Answer:
The u equation, a parabola
Step-by-step explanation:
This is a quadratic equation, since we have a variable 'x' raised to second power.
The vertex can be found using the formula x=-b/2a when the parabola is written as y=ax2 + bx +c.
I believe this is just a rectangle when you plot it out into a bar graph or a dot plot.

Answer:
10.4feet
Step-by-step explanation:
The set up wil form a right triangle
Length of the ramp is the hypotenuse
The length of the end of the ramp from the base= 10 feet (adjacent)
Angle of elevation = 15 degrees
Required
Length of the ramp
Using SOH CAH TOA
Cos theta = adj/hyp
cos 15 = 10/L
L = 10/cos15
L = 10/0.9659
L = 10.35
L ≈ 10.4 feet
Hence the length of the ramp is 10.4feet
