Answer:
75 seconds
Step-by-step explanation:
Here, we want to get her time 6 weeks ago.
We shall have an exponential model to link this all up
The exponential model would look like;
y = I(1 - r)^n
where y is the present time
I is the initial time she started with which we are calculating
r is the rate of change which is 2% = 2/100 = 0.02
n is the week number which is 6 in this case
So we have;
66 = I(1 - 0.02)^6
66 = I(0.98)^6
I = 66/0.8858
I = 74.5 seconds
This is approximately 75 seconds
Her time 6 weeks ago is 75 seconds

Answer:
A. 32.08
Step-by-step explanation:
The figure given is a right triangle. We would apply trigonometric ratios formula to find x.
Reference angle = 58°
Hypotenuse = x
Adjacent length = 17
Thus, we would apply the following:
Plug in the values
Multiply both sides by x
Divide both sides by Cos(58)
