You can use the Pythagorean theorem: a^2+b^2=c^2.

x^2+36=117 so x is 9 or -9 but since this is a length it would have to be positive so the answer is 9.

The Pythagorean Theorem states that the hypotenuse of a right triangle is equal to the square root of the sum of its squared sides, mathematically:

h^2=x^2+y^2, where h=hypotenuse and x and y are the side lengths.

In this case we can say:

(√117)^2=6^2+x^2

117=36+x^2

x^2=117-36

x^2=81

x=√81  since x>0

x=9 cm

If f(x) = (1/9)(9^x) what is f(3)
TiliK225 [7]

Answer:  The required value of f(3) is 81.

Step-by-step explanation:  We are given the following function :

f(x)=\left(\dfrac{1}{9}\right)9^x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

We are to find the value of f(3).

Substituting x = 3 in equation (i), we get

f(3)\\\\\\=\left(\dfrac{1}{9}\right)\times9^3\\\\=9^2\\\\=81.

Thus, the required value of f(3) is 81.
