Answer:
Average speed of go cart is 217.07 meters per minute.
Step-by-step explanation:
We are given the following in the question:
Length of straightway racetrack = 100 m
Diameter of semicircular end = 40 m
Radius =
Perimeter of racetrack =
Perimeter of semicircle + 2(Length of straightway) + Perimeter of semicircle
Speed =
Thus, average speed of go cart is 217.07 meters per minute.
A game center has a $5 admission fee (this is the y-intercept of the equation)
It charges $0.50 for each game played (this is the slope of the equation)
The equation can be written as
Where y is the cost and x is the number of games played.
To plot the graph, you can either find some (x, y) coordinates using the above equation.
Or you can plot it using the concept of slope and y-intercept.
Start at the point of y-intercept (0, 5)
The slope is 0.50 = 1/2
Then go 1 unit up and two units to the right that is your next point.
Repeat the same, 1 unit up and two units to the right that is your next point and so on...
Let us plot the graph
Scale: one small box = 1 unit
x-axis = number of games
y-axis = Cost ($)
