Aferris wheel of radius 100 feet is rotating at a constant angular speed ω rad/sec counterclockwise. using a stopwatch, the rider finds it takes 5 seconds to go from the lowest point on the ride to a point q, which is level with the top of a 44 ft pole. assume the lowest point of the ride is 3 feet above ground level. let q(t)=(x(t),y(t)) be the coordinates of the rider at time t seconds; i. e., the parametric equations. assuming the rider begins at the lowest point on the wheel, then the parametric equations will have the form: x ( t ) = r c o s ( ω t − π / 2 ) x(t)=rcos(ωt−π/2) and y ( t ) = r s i n ( ω t − π / 2 ) y(t)=rsin(ωt−π/2) , where r,ω can be determined from the information given. provide answers below accurate to 3 decimal places. (note: we have imposed a coordinate system so that the center of the ferris wheel is the origin. there are other ways to impose coordinates, leading to different parametric equations.) find r, find ω. during the first revolution find the times when the riders height is 80ft.

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

d is correct

step-by-step explanation:

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
