We have the function d, representing the distance from the ground of a person riding on a Ferris wheel:
If we consider the position of the person at t = 0, which is:
This position, for t = 0, will be the same position as when the argument of the sine function is equal to 2π, which is equivalent to one cycle of the wheel. Then, we can find the value of t:
Then, the wheel will repeat its position after t = 60 seconds.
Answer: 60 seconds.
Answer:28.50
I’m doing a lesson for iready and I had the same question
The numerator factored is
The denominator factored is
The x coordinate for the hole comes from the like factor (x - 1).
Set it equal to zero. x - 1 = 0 so x = 1
Plug the x value into the remaining fraction
The answer is (1,5)
If she cut off nine pieces of 2-inch ribbon, in all, that would be 18. After that, it would simply be the matter of subtracting 24 and 18.
24 - 18 = 6.
And there's your answer. Liz has 6 inches of ribbon left.
