f(n) = -1 . f(n − 1), for n = 2, 3, 4, ...
f(1) = 4
f(n) = - . /(n − 1), for n = 2, 3, 4, ...
f(n) = -4.(-3)'n – 1)
of(n) = 4.(-3)'n – 1)
f(1) = -4
f(n) = (n − 1), for n = 2, 3, 4, ...

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

363 square inches

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242
