If you mean the price is now 120% of the original, $<span>4.74 (3.95 * 0.8) is the new price.
If you mean the price is now 80% of the original, $3.16 (3.95 * 1.2) is the new price.</span>
You are multiplying by 3 each time. This sequence is geometric.
9 = 3*3 = 3^2
27 = 3*9 = 3*3*3 = 3^3
81 = 3*27 = 3*3*3*3 = 3^4
and so on.
The general rule is 3^x which is choice D
Answer:
2t-7
Step-by-step explanation:
It will take a rider 10 seconds to travel from the bottom of the wheel to a point 10 vertical feet above the bottom.
The radius of the wheel is 20 feet it revolves at the constant rate of one revolution per minute
using cos function,
cos ∅ = 
= 
= 
∅ 
we know that, 1 minute = 60 seconds =
1 second= 
∴Time =
=10 seconds
Hence, it will take a rider 10 seconds to travel from the bottom of the wheel to a point 10 vertical feet above the bottom.
