Answer:

Fourth option

Step-by-step explanation:

Given the following question:

(1, -4), (1, 18)

To find the distance between the two points we need to plot them on a graph and then count how many units are between the two.

On the same y-axis

$4+18=22$

"22 units" or the fourth option.

Hope this helps.

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:
