Answer:
Length of the ramp = 18.6 feet (Approx.)
Step-by-step explanation:
Given:
Horizontal distance (base distance) = 17 feet
Angle of elevation = 24°
Find:
Length of the ramp
Computation:
Cosθ = Length of base / Length of hypotenuse
Cos 24 = Horizontal distance (base distance) / Length of the ramp
Cos 24 = 17 / Length of the ramp
0.9135 = 17 / Length of the ramp
Length of the ramp = 17 / 0.9135
Length of the ramp = 18.6 feet (Approx.)
Option b. domain: {−12,−8, 0, 1} range: {0, 8, 12} is the right answer
Step-by-step explanation:
When the relation is given in the form of a table the x-values are the input to the function, hence domain and the y-values are the output of the function hence range.
Given table is:
[x] -12, -8, 0, 1
[y] 0, 12, 0, 8
The domain will be: {-12,-8,0,1}
And Range = {0,8,12}
Hence,
Option b. domain: {−12,−8, 0, 1} range: {0, 8, 12} is the right answer
