The value of x is 1.66
Step-by-step explanation:
Let use revise the rules of exponential and logarithmic equations
1. If y =
, then 
2. 
Use the rules above to solve the problem
∵ 
- Subtract 2 from both sides
∴ 
change the exponential equation to logarithmic equation
∴ 
∵ 
∴ x = 
∴ x = 1.66
The value of x is 1.66

Answer:
You would plot the following points, remembering that they’re in the form (x,y) = (time, height):
(1,35) (2,60) (3,92) (4,120) (5,175)
The ordered pairs would be closer together, and there would be 4 times more of them if you were to measure every 15 seconds instead. You would have a line with more points that were closer together.
