1. According to the given graph it is possible to define A - amplitude and B - frequency of this function, then to substitute them to its equation.
2. A=5 (max. and min. values for vertical); B=2 (two periods in the length 2π).
3. answer: y=5sin2x.
Answer:
<u>2/3</u>
Step-by-step explanation:
P (not pink) :
- Total - Pink counters / Total
- 4 + 5 + 3 - 4 / 4 + 5 + 3
- 8/12
- <u>2/3</u>
The answer will be a because they are similar and by law the ratio can be cubed to find ratio of volume
5m-8=3m+8
(Plus the '8' to both sides)
5m=3m+16
(Subtract '3m' from both sides)
2m=16
(Divide by 2)
m=8
