Answer:
Jamie must sprint 107 meter to pass Shelly at point A.
Step-by-step explanation:
Circumference of a sector of the circle is represented by,
Circumference = 
where θ = central angle subtended at the center by an arc
r = radius of the circle
= 
= 34.1667π
= 107.34 meter
≈ 107 meter
Therefore, Jamie must sprint 107 meter to pass Shelly at point A.
It's b)
you can test it by multiplying 6 by 4

Answer:
5
Step-by-step explanation:
We have an equation and are asked to find the input of x when y = 7.
The output = y = 7
The input = x
7 = 2x - 3
2x - 3 = 7
We need to find a number that multiplied by 2 which then is subtracted by 3 equals 7. We can use the backwards method to solve our answer.
2x - 3 = 7
7 + 3 = 2x
10 = 2x
Solve for x by dividing 2 from both sides :
x = 5.
Therefore, you would need an input of 5 to get 7 as the output.
Proof :
2(5) - 3 = 7
10 - 3 = 7
1. The counterclockwise rotation by 90° about the origin has rule:
(x,y)→(-y,x).
Then
(-3,-1)→(1,-3).
2. Translation 4 units up has rule:
(x,y)→(x,y+4).
Then
(1,-3)→(1,1).
Answer: after composition of transformations the image point has coordinates (1,1).
