Since PB' = (3/5)*PB, the scale factor is 3/5, the 2nd choice.
Answer:
Red : 5/12
Blue : 1/3
Green: 1/6
Yellow : 1/12
Step-by-step explanation:
5 red marbles + 4 blue marbles + 2 green marbles + 1 yellow marble = 12 total marbles
5 red marbles / 12 total marbles = 5/12
4 blue marbles / 12 total marbles = 4/12 = 1/3
2 green marbles / 12 total marbles = 2/12 = 1/6
1 yellow marbles / 12 total marbles = 1/12
Answer:

Step-by-step explanation:
Given

Required
Determine the period
A sine function is represented as:

Where

By comparing:
and 

So:

So, we have:



Hence, the period of the function is 
1/2 is 0.5 The answer is 0.5 because 1/2 is like a half and we know that a this fraction is less than 1. So .5+.5=1 THE ANSWER IS 0.5!
Answer:
The polynomial is:

Step-by-step explanation:
A third degree polynomial can be written in function of it's zeros
the following way:

In which a is the leading coefficient.
Integer coefficient that have zeros: 1+2i, 1-2i, -4
Leading coefficient: 1
So




Since
