Answer 2

A Ferris wheel has a radius of 80 feet. Two particular cars are located such that the central angle between them is 165º. To the nearest tenth, what is the length of the intercepted arc between those two cars on the Ferris wheel?

Answer 3

Length of arc = r * theta * pi/180
when theta is in degrees
here,
4= 80
theta = 165

Answer 4

**r = 80

Answer 5

Is that it ?

Answer 6

yeah......just plug in values

Answer 7

I got 230.4 feet

Answer 8

i got the same :)
you can also keep the answer in terms of pi, if you want
73.333pi ft or 230.4 ft

Answer 9

Thank you :) 1 more.

Answer 10

wave is modeled with the function y = 1/2 sin 3Θ. Describe the graph of this function, including its period, amplitude, and points of intersection with the x-axis.

Answer 11

you have options/ choices, right ?

Answer 12

nope

Answer 13

y= A sin (wt)
is the sine wave with amplitude A
time period T = 2pi /w

Answer 14

so, what about y = 1/2 sin 3Θ. ?

Answer 15

wait huh ?

Answer 16

A = amplitude there.
and period , you can find from w
