The answer is either a or d but we know she did all of this for more than 52 minutes.
Answer:
See explanation
Step-by-step explanation:
Assuming you want to find the 3rd term of the geometric progression defined explicitly by 
, then we have to substitute n=3 to obtain:
This will give us:
We evaluate to obtain:
My gut is telling me that the answer is C. 5
I think question 2 is 3 millimeters
Because diameter = 2r (R = radius)
Each angle on a triangle would add up to 180 degrees. Since a ladder goes straight up, that angle would be 90 degrees. If you add that with the 39 degree angle, you'd get 129. Subtract that from 180 and you have your answer.
