Answer: The total distance Fiona covers in two laps of the race = 880 meters
Step-by-step explanation:
Given : Fiona races BMX around a circular dirt course.
The radius of the course is 70 meters.
Then , Circumference of circular dirt course = 
=
![[\text{Use }\pi=\dfrac{22}{7}]](https://tex.z-dn.net/?f=%5B%5Ctext%7BUse%20%7D%5Cpi%3D%5Cdfrac%7B22%7D%7B7%7D%5D)
Now , the total distance Fiona covers in two laps of the race = 2 x (Circumference of circular dirt course)
= 2 x (440 meters)
= 880 meters
Hence, the total distance Fiona covers in two laps of the race = 880 meters
Answer:
y = 3x
Step-by-step explanation:
A proportional function has the equation
y = kx, where k is the constant of proportionality and also the slope of the line.
Answer: y = 3x
Answer:
m = -1/3
Step-by-step explanation:
To find our <em>m</em> in y = mx + b, (our slope is <em>m</em>), we use slope formula: 
We are given 2 points, so we plug it into the slope formula:

m = -1/3
So our slope is -1/3.
Answer:
X-intercepts: (80,0)
y-intercepts: (0,200)
Step-by-step explanation:
(To find the x-intercept, substitut in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y. As shown in the pictur)
