Answer:

Step-by-step explanation:

1. 1.

2. That would be the GCF ( The Greatest Common Factor) of 15 and 25:

15 = 3 * 5

25 = 5 * 5

That is 5 liters.

3. This is the GCF:

44 = 2 * 2* 11

121 = 11 * 11

The answer is 11.

4. Find the GCF:

25 = 5 * 5

35 = 5 * 7

Answer is 5 inches.

A buoy starts at a height of 0 in relation to sea level and then goes up. Its maximum displacement in either direction is 6 feet

svet-max [94.6K]

Answer:

$h=6*sin(\frac{2\pi }{8}t)$

Step-by-step explanation:

Since the buoy is going up and down, its motion is oscillatory, and therefore, it can be described by a trigonometric function.

The buoy starts at height of 0 in relation to the sea level, which means at time $t=0$ , $h=0$ , this tells us that trigonometric function modeling the buoy must be the sine function since for

$h=A*sin(wt)$ , at $t=0$ , $h=0$ .

The maximum displacement of the buoy in either direction is 6 feet, this means we have

$h=6*sin(wt)$

now we need to figure out $w$ .

The time it takes the buoy to get from its lowest point to its highest point is 4 seconds, that means the period $T$ of oscillation is $2*4=8$ seconds. The buoy returns to to the same place after one period, this means if the buoy started from 0, it will return to 0 after 8 seconds; therefore, from $h=6*sin(wt)$ the we have:
