Determine whether each pair of functions are inverse functions. 1) f(x) = 8x – 10, g(x) = (x + 10) 2) f(x) = 4x + 5, g(x) = 4x –
Y_Kistochka [10]

Answer:

Step-by-step explanation:

To find the inverse of a function you take it in y=f(x) form, switch x and y and then solve for the new y.

So I'll do the first one.

f(x) = 8x-10

y=8x-10 Now switch x and y

x = 8y-10 Now solve for y.  

x+10=8y

(x+10)/8 = y

g(x) is not that, so it is not the inverse.  Can you figure out the second one?

Find the approximate value of the circumference of a circle with the given radius. UseT 3.14. Round your results to one more dec
Temka [501]

Answer:

25.1 inches

Step-by-step explanation:

Radius of the circle = 4 inches

We have to calculate the value of Circumference of the circle.

The formula to calculate the circumference is:

Circumference = 2πr

We have to use π = 3.14, as said in the question:

So using the values, we get:

Circumference = 2 x 3.14 x 4 = 25.12 inches

Number of decimals in radius is zero, so we have to round the answer to one decimal place as said in the question.

Therefore, the circumference of the circle rounded to one decimal place will be 25.1 inches
