Answer:
8 by 8.
Step-by-step explanation:
A triangular sail to be constructed with a vertical and a horizontal poles for support. The combined weight of the poles cannot exceed 80 pounds and the poles weigh 5 pounds per foot gives us a total length of 80/5=16 feet. Let us call the length of horizontal pole by x and we have (16-x) for the vertical one. We want to maximize area of the sail, so [tex] A(x)= x (16-x)/2 [\tex] is the function we want to maximıze on [0, 16].
Answer:
(5m^3+4)(5m^3-4)
Step-by-step explanation:
(*) A^2 - B^2 =(A+B) (A-B)
25m^6-16=
(5m^3)^2 - 4^2=(*)
(5m^3+4)(5m^3-4)
First you find the square root of 16, which is 4. Then multiply 4 by 20, which is 80. Therefore, your answer is 80.
