A scuba diver at a depth of 80 ft begins her ascent to the ocean surface. Her rate of change in depth is 2 ft/s. Which equation represents her depth in feet t seconds after she begins her ascent?

Step-by-step explanation:

The rate of change of depth is given as 2 ft/s which is constant.

Let depth be represented by y.

At time t = 0, depth is -80 feet.

At any given time t, depth will be y.

Hence, rate of change of depth can be written as:

∴y = 2*t - 80

This equation describes her depth when she begins her ascent

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
