Alex777 [14]

Answer:

20-5 11/12= 9 11/12

Step-by-step explanation:

we do (3 2/3 + 2 1/4+ 2 1/3 )which is

           3 8/12.    2 3/12    2 4/12 (common denominator)

then add 3 8/12 and 2 3/12 and 2 1/3 to get 10 1/12 then we get 20- 10 1/12 to get a final answer of 9 11/12

Which of the following options is an equivalent function to f(x) = 2(5)^2x? choices: f(x) = 50^x f(x) = 100^x f(x) = 2(25)^x f(x
Stells [14]

For this case we have the following function:

f (x) = 2 (5) ^ {2x}

By power properties we can rewrite the function as follows:

f (x) = 2 ((5) ^ 2) ^ x

We have then:

(5) ^ 2 = 25

Then rewriting the function we have:

f (x) = 2 (25) ^ x

Answer:

an equivalent function to f (x) = 2 (5) ^ {2x} is:

f (x) = 2 (25) ^ x
