Answer:
i dont know im just doing this for the points
Answer:
The answer is 8.
Step-by-step explanation:
I used the calculator...
I just typed these equations on the calculator because its hard to do it in your head.
log 5root5 125 = 2 x=2
log 2root2 64 = 4 y= 4
The question wants the product of x and y which translates to x times y. x*y
SO.... 2*4 = 8
Complete the table of values for the function f(x) = (1/3)x for a, b, and c. x : -2, -1, 0, 1, 2. f(x) : a, b, c, 1/3, 1/9

Given:
The function is

To find:
The missing values for a, b, and c in the given table.
Solution:
We have,

At x=-2,

![\left[\because \left(\dfrac{a}{b}\right)^{-n}=\left(\dfrac{b}{a}\right)^{n}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbecause%20%5Cleft%28%5Cdfrac%7Ba%7D%7Bb%7D%5Cright%29%5E%7B-n%7D%3D%5Cleft%28%5Cdfrac%7Bb%7D%7Ba%7D%5Cright%29%5E%7Bn%7D%5Cright%5D)

At x=-1,

![\left[\because \left(\dfrac{a}{b}\right)^{-n}=\left(\dfrac{b}{a}\right)^{n}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbecause%20%5Cleft%28%5Cdfrac%7Ba%7D%7Bb%7D%5Cright%29%5E%7B-n%7D%3D%5Cleft%28%5Cdfrac%7Bb%7D%7Ba%7D%5Cright%29%5E%7Bn%7D%5Cright%5D)

At x=0,

![\left[\because a^0=1, a\neq 0\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbecause%20a%5E0%3D1%2C%20a%5Cneq%200%5Cright%5D)
Therefore, the missing values of a,b and c are 9, 3, and 1 respectively.
A^2 = b^2 + c^2 -2bc * cos(A)
a^2 = 144 + 225 -360 * .5
a^2 = 189
a = 13.748
