A carnival ride is in the shape of a wheel with a radius of 25 feet. The wheel has 20 cars attached to the center of the wheel.
Vladimir79 [104]

Centre angle will be 360° as its totally a circle.

  • radius=r=25ft

Angle between two cars=360/20=18°

  • Arc length=L

\\ \sf\longmapsto L=\dfrac{\theta}{360}(2\pi r)

\\ \sf\longmapsto L=\dfrac{18}{360}(2\pi(25))

\\ \sf\longmapsto L=\dfrac{1}{20}(50\pi)

\\ \sf\longmapsto L=2.5\pi ft

Now

Area be A

\\ \sf\longmapsto A=\dfrac{1}{2}Lr^2

\\ \sf\longmapsto A=\dfrac{1}{2}(2.5\pi)(25)^2

\\ \sf\longmapsto A=625(2.5)\pi\dfrac{1}{2}

\\ \sf\longmapsto A=1562.5\pi/2

\\ \sf\longmapsto A=781\pi ft^2=

Write and equation in slope intercept form (y=mx+b) for the graph below
soldier1979 [14.2K]

Answer:

y=1/3x+0 or y=1/3x

Step-by-step explanation:

find the slope by taking two points and putting them in

y2 - y1/x2 - x1

so, (3,1) and (6,2) becomes 2-1/6-3 or 1/3 so, slope is 1/3

then to find y intercept you can put a point (6,2) and slope (1/3) into slope intercept form y - y1 = m(x - x1)

y - 2 = 1/3(x-6)

when you solve this you get y = 1/3x + 0, so y intercept is 0. you can also see. this on the graph given
