A ferris wheel is 10 meters in diameter and boarded from a platform that is 5 meters above the ground. The six o'clock position

on the ferris wheel is level with the loading platform. The wheel completes 1 full revolution in 2 minutes. The function h = f(t) gives your height in meters above the ground t minutes after the wheel begins to turn. Write an equation for h = f(t).

Answer:

The equation is:

f (t) = 4 + 5 (1 - cos (2pi t / 2))

Step-by-step explanation:

with the previous exercise we look for the equation for h = f (t)

So the data we have are

Wheel diameter = 10m (wheel radius = 5m)

1 wheel gets 1 revolution in 2 minutes.

the beginning of a entry will be related to that f (0) = 4

our wish is that f (z) get at least 4 with an amplitude of 5 (this value determines the radius of the wheel) for 2 minutes

with this the particle f (t) is transformed into

f (t) = 4 + 5 (1 - cos (2pi t / 2))

We know that the maximum value of cos in t will be 0, 1 -cos has minutes, the result will be as follows:

f (t) = 4 + 5 (1 - cos (2pi t / 2))

There were 287 music books and 134 science books in the store. After some books were sold there are 159 books left. How many boo
stiks02 [169]

Answer:

262 books sold

Step-by-step explanation:

This is a very vague word problem, but if it truly is just asking the amount of books sold (regardless of music or science), here's how to get the answer:

1. 287+134=421 - first you want to add together the two types of books to get the total amount of books in the store

2. 421-x=159 - create an equation and solve.

3. -x=-262 - follow order of operations and subtract 421 on both sides in order to isolate the variable

4. x=262 - divide each side by -1 to make the variable positive.

If you'd like an easier way, you can just:

1. 421-159=262 - it's easier, but my math teacher would count us wrong if we didn't do equations a specific way. Good luck!
