To investigate water quality, the Columbus Dispatch took water specimens at 16 Ohio State Park swimming areas in central Ohio. T

hose specimens were taken to laboratories and tested for E. Coli, which are bacteria that can cause serious gastrointestinal problems. For reference, if a 100 100 -milliliter specimen (about 3.3 3.3 ounces) of water contains more than 130 130 E. Coli bacteria, it is considered unsafe. Here are the E. Coli levels per 100 100 milliliter found by the laboratories:

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
Murrr4er [49]

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))
