If prices increase at a monthly rate of 1.9% by what percentage do they increase in a year

Mathematics
1 answer:
salantis [7]4 years ago
6 0
Let the initial price be 100. Price after 1 month is 101.9. common ratio is r = 101.9/100 = 1.019

After 12 months, the price will be:

A1 x r ^n-1

= 101.9 * (1.019)^12-1

= 101.9 * 1.019^11= 125.34

So the yearly increase would be: 125.34 – 100 = 25.34

Therefore, the yearly price rise percentage is 25.34/100 x 100 = 25.34%

a ramp 29 ft long rises to a platform. the bottom of the platform is 20 ft from the foot of the ramp. find x, the angle of eleva
Simora [160]
We will be using the cosine function to figure this out. 
The ramp, ground, and platform form a right triangle. 
The hypotenuse is 29, and the side adjacent to ∠x is 20.
SO:
      Cos ∠x = 20/29
      Cos ∠x = 0.68965517241379
 
Use the function on your calculator to find what angle has a Cos of 0.6896551
          Cos 0.6896551 = 46.397°

ANSWER: the angle of elevation is 46.4°

Hope this helps! God bless. :)

gizmo_the_mogwai [7]

The economic output is rising and is expected to continue rising in the coming months, the economy is currently in the expansion stage of the business cycle.

The business cycle consists of the following stages which changes with time;

  • Expansion stage: continuous rise in economic output.
  • Peak stage: maximum economic output.
  • Contraction (recession) stage: a continuous decline in economic output.
  • Trough stage: the point of lowest economic output.

Thus, when the economic output is rising and is expected to continue rising in the coming months, the economy is currently in the expansion stage of the business cycle.
