What is the value of the function at x = −2?

3.

Step-by-step explanation:

We have been given graph of a function. We are asked to find the value of our given function at .

To find the value of our given function at , we need to find the y-value of our given function when .

We can see that value of y-coordinate is 3, when , therefore, at the value of the function is 3.

what

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
