Answer
Find out the how high up the wall does the ladder reach .
To proof
let us assume that the height of the wall be x .
As given
A 25-foot long ladder is propped against a wall at an angle of 18° .
as shown in the diagram given below
By using the trignometric identity

now
Base = wall height = x
Hypotenuse = 25 foot
Put in the trignometric identity


x = 23.8 foot ( approx)
Therefore the height of the ladder be 23.8 foot ( approx) .
1.50x +2=y Where x is how many miles and y is the total
Answer:
$204
Step-by-step explanation:
The question is at what price x will the company maximize revenue.
The revenue function is:

The price for which the derivate of the revenue function is zero is the price the maximizes revenue:

The company will maximize its revenue when the price is $204.
Answer:
Yes.
Step-by-step explanation:
Both yards do cost the same.
$15.00 divided by 2 is equal to 7.5.
$37.50 divided by 5 is equal to 7.5.
Therefore, both yards cost the same.
I assume it is:
2x/(-5x+x^2), then you can simplify the x, but only if it is not zero:
2/(x-5), for x different to zero.
