This problem is resolved with the Pythagorean Theoreme.
It states that the length of the side that is the hypotenuse (the side opposite the right angle) is equal to the square root of the sum of the length of the other two sides squared.
So we know that the ground and the building form the right angle, so the hypotenuse is the length of the ladder (L) and the building (B) and the ground (G) are the other sides of the triangle (legs). So by the pythagorean theoreme:
L = √ (G^2+B^2)
As we already know the length of the hypotenuse, we have to isolate the variable that we don’t know (B).
B = √(H^2-G^2)
Replacing:
B = √(7^2-2^2)
B= √(49-4)
B = √45
B = 6,7 feet
I hope you find my answer helpful.
If this was a triangle, the answer would be 35 degrees. Can you plz show a graph if you have one though?
Answer:
$14,600
Step-by-step explanation:
The function P(a) = 25,000a - 1000 gives the amount of potatoes, P, in kilograms, that he expects to produce from planting potatoes on a acres of land.
If Ben plants on 3 acres of land, then the amount of potatoes expected will be:
P(3) = 25,000(3) - 1000 =74,000kg
The amount of money, M, in dollars, that Ben expects to make if he produces p kilograms of potatoes is given by the function:
M(p) = 0.2p - 200
Since Ben produces 74000kg on 3 acres, the amount of money he is expected to make is then:
M(74000) = 0.2(74000) - 200
=$14,600
Ben will make $14,600 if he sells all of the potatoes produced on the 3 acres.
