Answer:
Yes this is a linear function f(x) = ex+30
e = hourly rate
x=hours
f(x) = total earnings
Area of sector = 1/2 * r^2 * x where r = radius and x = angle in radians
86 = 1/2 * r^2 * pi/4
r^2 = 2 * 86 * 4 / pi = 219
r = sqrt 219
= 14.80
4 miles because there are 5280 ft in one mile so if you were to multiply that by 4 you would get 21120 ft
Answer:
y = 2.5x + 0
Step-by-step explanation:
Use the slope formula and slope-intercept form y = mx + b to find the equation.
circumference is C = πd, d = diameter.
we know the diameter is 60, so one time around the track is just C = π60 which if you plug that in your calculator, we get C ≈ 188.4955592153876.
