Answer:
Option B - graphing is the correct answer.
Step-by-step explanation:
To solve a system of inequalities we need graphing. Inequality tells us about the relative size of two values. When we graph the x and y co-ordinates, the solution is not the drawn line, but the area of the coordinate plane that satisfies the inequality. In inequalities, multiple solutions can be possible.
Plug and chug method does not a complete solution, it only tells where a point belongs. Guess and check does not apply here.
The y-intercept is where on the graph the line is intersecting the y=axis. Slope is in the form y=mx+b (b=y-intercept, mx=how far up and over.)
It is a an exponential function. And it is not A.
The answer is B)
Answer:
Decreases
Step-by-step explanation:
We need to determine the integral of the DE;
We can solve this by integration by parts on the left side. We expand the fraction 1/P²:
let
Substitute u in:
Therefore the equation is:
We simplify:
As t increases to infinity P will decrease
