A ferris wheel 60 feet in diameter has its center 35 feet above the ground and makes one revolution every 10 seconds. How fast is the height of a point on the rim increasing or decreasing relative to the ground when the point is 50 feet above the ground?

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

1 3 5

step-by-step explanation:

i took the test: )

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
