Nick put a ladder up against the house to try and reach a light that is out and needs to be changed. He knows the ladder is 10 feet long and the distance from the base of the house to the bottom of the ladder is 4 feet. What is the angle of elevation of the ladder?

a^2+b^2=C^2

10^2+4^2=C^2

100+16=C^2

square root of 116= square root of C^2

square root of 116= 10.77

umm nvmd, I read it wrong

but the answer is 90 degrees. ignore the math lol

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
