A differential equation is one that contains the derivative of a function. For example f(x) + 3 = 4f'(x) - 2. Usually you will be given one of the functions and initial conditions if you have to solve.
Answer:
75.2
Step-by-step explanation:
multiple 8 by 9.4
First, get the difference between the price level changes.

Then, divide it by the initial price level, which is 109.

Multiply by 100 to get its percent.

Thefore, the inflation rate during the year is 3.67 percent.
- 3x + 2x + 5 + 5x + 15 = 180 [angles on a line add to 180 degrees]
- 10x + 20 = 180 [combine like terms]
- 10x = 160 [subtract 20 from both sides]
- x = 16 [divide both sides by 10]
Arc AB measures 3(16) = 48 degrees.
Arc BC measures 2(16) + 5 = 41 degrees.
