As the Ferris Wheel Turns
4. NEW Ferris Wheel:
The radius of the Ferris wheel is 65 feet.
The speed of the wheel, makes a
complete turn every 45 seconds, and moves
counterclockvise.
• The height of the center of the wheel
is 80 feet off the ground.
a) What is the angular speed for this Ferris Wheel?
900
b) How many seconds does it take for Mrs Fogiel and
Mrs Koch's cart to go each of the following distances?
i. From the 3 o'clock to the l o'clock position?
ii. From the 3 o'clock to the 8 o'clock position?
ii. From the 3 o'clock to the 6 o'clock position?

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

x = 12

y = 1

for the points!

answer: i think you should do the math and pay attention in class : )

step-by-step explanation:

that is truly what   think but if i get the answer i will
