Answer:
The ramp must cover a horizontal distance of approximately 19.081 feet.
Step-by-step explanation:
Given the vertical distance (
), measured in feet, and the angle of the wheelchair ramp (
), measured in sexagesimal degrees. The horizontal distance needed for the ramp (
), measured in feet, is estimated by the following trigonometrical expression:
(1)
If we know that 
and 
, then the horizontal distance covered by this ramp is:
The ramp must cover a horizontal distance of approximately 19.081 feet.
Answer:
B
Step-by-step explanation:
The volume of a square pyramid can be found using:
v=1/3 bh
Where b is the area of the base, and h is the height
First, let's find the area of the base
a=l*l
We know the length is 5, so we can substitute it in
a=5*5
a=25
Now we know b(area), is 25, and we know the volume is 75, so we can substitute them in
v=1/3 bh
75=1/3(25)h
Divide both sides by 1/3, or multiply both sides by the reciprocal, 3/1
225=25h
Divide both sides by 25
h=9
So, the height is 9 feet , or choice B
The answer is the slope is -3/2!
Answer:
x = -4.37
x = 1.37
Step-by-step explanation:
x^2+2x-6 = 0
factor
(x+4.37)(x-1.37) = 0
x = -4.37
x = 1.37
