An inverse operations is the reverse of the equation. For example, since it's 102 ÷ 3 = 34, to get the inverse you would take the opposite sign of "÷" and make it "×," while changing the equal sign to make the statement true. The inverse operation used to verify this is 102 = 3 × 34

Given the figure. Find AC.

Image is missing, so i have attached it.

Answer:

AC = 10sin 40°

Step-by-step explanation:

From the diagram attached, using terms in trigonometric ratio, AC is the opposite side, BC is the adjacent side and AB is the hypotenuse.

Thus, since we want to find AC;

We know that in trigonometric ratios; opposite/hypotenuse = sin θ

In the diagram, θ = 40° and AB = 10

Thus,

AC/10 = sin 40°

Multiply both sides by 10 to get;

AC = 10sin 40°

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:

$f (x) = 2 (25) ^ x$
