<span>square root of 4/25=0.4</span>
Answer:
y = 3sin(2x+pi)
Step-by-step explanation:
We know that a is equal to 3 because the distance from 3 to the midpoint 0 is 3
We also know that is a phase shift of pi/2 as that is where the new start of our sine function lands
We know there is a compression of 2 as our period has changed from 2pi to pi
So naturally we change pi/2 to pi since we put the 2 inside the parenthesis
Best of luck

Answer:
Step-by-step explanation:
Let's Jiri's age be "J" and Pamela's age be "P".
P = 9 + J (Pamela is 9 years older than Jiri.) ... equation 1
P + J = 107 (the sum of their ages is 107) ... equation 2
Put equation 1 into equation 2:
(9+J) + J = 109
9 + 2J = 109
2J = 109 - 9
2J = 100
J = 100/2
J = 50
Therefore, Jiri's age is 50.
