A circular swimming pool has a radius of 15 ft. There is a path all the way around that pool that is three feet wide. A circle has a radius of 15 feet. A larger circle goes around the smaller circle that is 3 feet wide. What is the circumference of the outer edge of the path around the pool? Use 3.14 for Pi. 56.52 ft 94.20 ft 113.04 ft 114.04 ft

113.04ft

Step-by-step explanation:

Radius of circle + width of outer circle

15 + 3 =18ft

Circumference of the outer edge becomes

2 × 3.142 × 18

=113.04ft

i tuk the test and got it right

Part A: Linear relationship

Part B: Using the dividing method

Slope = -3.325

y-intercept is (0, 88.5)

Step-by-step explanation:

Part A

The is an approximately linear relationship between the temperature of his city and the number of chocolate sold

Part B

The line of best fit can be drawn by

1) Plot the data points on the graph

2) Divide the number of data points into two with a vertical dotted line

3) Mark the center of the data on each side of the dividing central line with an a or x

4) Draw a straight line through the x marks that extends to the plot edges

5) The straight line drawn is the line of best fit

The approximate slope is found from points (0, 90) and (20, 20) using the formula for gradient, m, such that we have;

Where:

y₁ = 88

x₁ = 0

y₂ = 22

x₂ = 20

Therefore;

From the graph, the y-intercept is approximately (0, 88.5) while the x intercept is approximately (26.5, 0)
