3 more than the produce of 12 and 4.
If they all painted at the same rate the equation is this
mothers 8
daughters 12 at 220 sq ft
mothers 6
daughters 8 at 152 sq ft
220 +152 =372 divided by 34 (because they all painted at the same rate)=10.94 sq ft they each painted
Answer:

9514 1404 393
Answer:

Step-by-step explanation:
The first term is 2, so part of the recursive definition is ...
f(1) = 2
The common ratio is 6/2 = 3, so each term is 3 times the previous one. That part of the recursive definition is ...
f(n) = 3·f(n -1)
These two parts of the definition match choice C.
Answer:
The first occurence of t for which x = 0 is t = 0.5.
Step-by-step explanation:
The harmonic motion is described by the following equation.

What is the first occurrence of a value of t for which x = 0?
This is t when
. So




The inverse of the cosine is the arcosine. So we apply the arcosine function to both sides of the equality.





The first occurence of t for which x = 0 is t = 0.5.
