Answer:
$110
Step-by-step explanation:
We are looking for the decrease in money per desk purchased. Because the x-axis is the number of desks purchased, what we have to find is the (opposite) of the slope. The formula to represent slope can be written as:
We can substitute the points given, (2, 480) and (5, 150) and simplify:
We would multiply by -1 because we are asking for the decrease, and negative increase is decrease. -1 * -110, gives us $110
Answer:
The ramp should be 32.9 feet longer.
Step-by-step explanation:
When the ramp is at to the ground, its length can be determined by applying the appropriate trigonometric function. Let the length be represented by l, so that;
Sin θ =
Sin =
l =
=
= 33.0048
l = 33.0 feet
When the angle is reduced to , the length of the ramp would be;
Sin θ =
Sin =
l =
=
= 65.9152
l = 65.9 feet
Change in length of ramp = 65.9 - 33.0
= 32.9
The ramp should be 32.9 feet longer.
