Which of the following exponential regression equations best fits the data shown below?

The correct option is D.

Step-by-step explanation:

The general exponential regression equations is

                     .... (1)

where, a is initial value and b is growth factor.

Using graph calculator, we get

Put the value of a and b in equation (1), to find the exponential regression equation.

Substitute a=3.53 and b=4.37 in equation (1).

The exponential regression equations that best fits the data is .

Therefore the correct option is D.

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
