Number 4 :)
if wrong let me know
Is that your actual work because if it is then ummm.... i- i feel bad for you :((
Hello!
To find the circumference, you multiply the diameter by pi. We will do so below.
2.5
≈7.85
a. 7.85 feet
___________________________________________________
To find how many rotations it will take to travel a mile, we will need to divide our mile by our circumference.
5,280/7.85≈672.61
b) 672.61
I hope this helps!
First solve for the slope, m using the two points given. It doesn't matter which point you choose as point 1 or 2 as long as you're consistent.
m = (y2 - y1)/(x2 - x1)
point 1: (–6.4, –2.6)
point 2: (5.2, 9)
m = (9 - -2.6)/(5.2 - -6.4)
m = (9 + 2.6)/(5.2 + 6.4)
m = 11.6/11.6
m = 1
put the newly found slope into the linear equation for m
y = (1)x + b
y = x + b
Now solve for the y-intercept, b
by putting one of the given points
9 = 5.2 + b
b = 9 - 5.2
b = 3.8
final equation:
y = x + 3.8
