Will upvote and would like an explanation as well
the table below represents the velocity of a car as a function of time:

time
(hour)
x velocity
(miles/hours)
y
0 50
1 52
2 54
3 56
left side is x and right side is y

part a: what is the y-intercept of the function, and what does this tell you about the car? (4 points)

part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points)

part c: what would be the domain of the function if the velocity of the car was measured until it reached 60 miles/hour and the car does not change motion? (2 points)

(A): When it asks for a y-intercept, it is basically asking what is the value of y when x=0. In this case, when x=0, y=50. So the y-intercept is 50.

(B): The avg. rate of change is the same as asking for slope. So we want to use slope formula -> . Using the values in your table -> 

(C) You can generate a linear function with a y-intercept and a slope using the following formula -> y= (average rate of change)*x + y-intercept -> Then set y=60 and solve for x. Your domain is [0, solved value] with square brackets since you are including the endpoints.

answer: i'm not sure

step-by-step explanation:

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
