A ferris wheel has a radius of 20 m, makes a full rotation in one minute and the axle (center of wheel) stands 25 m above the ground. Write a cosine function which models the height of a chair of the ferris wheel that starts at the top, where x is in seconds?

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

should have been evaluated with one odd value and one even value. the expressions have equivalent values when . when , the first expression has a value of 3 and the second

step-by-step explanation:

shorter then the tree

the answer is

21

i did this one. so you should get it right.
