Mary opened a savings account that compounds interest yearly. She deposited money only when she opened her account. The amount, A (t), in Mary's account t years after it was opened is given by the equation A (t) = 530 (1.002)^t. What is the growth
factor of this function?

Actually Welcome to the concept of growth rate.

Answer is D. 1.002

Since, it has power t for the growth rate to increase.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
