Answer:
A. Circumference is 16
C. Diameter is 25.5
Step-by-step explanation:
circumference = 2πr
Diameter = r/2
A.
Diameter = 5 or radius = 5/2
Circumference = 2*3.14*5/2 = 15.7 or 16
C.
Circumference = 80 = 2πr
Radius = 12.74
Diameter = 2*radius = 25.48 or 25.5

Answer:
You can model a data using a linear function when the dependent variable is a multiple of the independent formula plus another constant by the y-intercept. The constant multiple is represented by the slope. In real life problems, linear function is applied when you want to determine the cost given with a slope which is represented by cost per unit time. For example, the cost of wifi connection is $10/month plus $2 inclusive for phone charges. The linear function would be:
C = 10t + 2
where C is the cost and t is time in months
