An equation to model this scenario would be 2s=28, with "s" being the string.
Answer:
The rate of change in the submarine's elevation is 26.0 feet per second.
Step-by-step explanation:
She begins 151 feet below sea level
Thus, her initial point is y₁ = 151 feet below sea level
i.e. at t₁=0 seconds, y₁ = 151 feet below sea level
After descending for the 3 seconds, she is 229 feet below sea level.
Thus, her second point is y₂ = 229 feet below sea level after 3 seconds
i.e. at t₂=3 seconds, y₂ = 229 feet below sea level
The rate of change is basically the slope. Thus, the rate of change can be obtained by taking the slope.
slope = rate of change = (y₂ - y₁)/(t₂ - t₁)
= (229 - 151) / (3 - 0)
= 78/3
= 26.0
Therefore, the rate of change in the submarine's elevation is 26.0 feet per second.

btw you know that x= the multiplication sign right.
<em>Answer:</em>
<em>A proportion can be used to find the distance on the map that represents 50 miles, you can calculate this using the following steps:
</em>
<em>
</em>
<em>200 miles ... 5 inches
</em>
<em>50 miles ... x inch = ?
</em>
<em>
</em>
<em>200 * x = 5 * 50
</em>
<em>x = 5 * 50 / 200
</em>
<em>x = 1.25 inch
</em>
<em>
</em>
<em>The correct result would be x = 5 * 50 / 200.</em>
