A consumer price index (CPI) measures changes in the price level of market basket of consumer goods and services purchased by households.The annual percentage change in a CPI is used as a measure of inflation
CPI=(1,445÷745)×100=194
Answer:
A and D
If you take all the numbers and add them together they all equal and equivalence to 1.6a and 1.7d. So, if you take the numbers then add them it is A and D
Answer:
OMG IS THAT PROBABILITY ON A GRAPH THOUGH PLEASE REPLY SO I COULD ANSWER...
Step-by-step explanation:
Answer:
The equation of the parabola is
.
Step-by-step explanation:
Since the directrix is of the form
, the parabola is vertical. The vertex of the parabola (
) is the midpoint between the focus (
) and a point of the directrix (
), that is to say:
(1)
If we know that
and
, then the coordinates of the vertex of the parabola:


The vertex factor (
) is the distance of the focus with respect to the vertex:
(2)
If we know that
and
, then the vertex factor is:


The equation of the parabola in the vertex form is described below:
(3)
Where:
- Independent variable.
- Dependent variable.
- Coordinates of the vertex.
If we know that
and
, then the equation of the parabola is
.
Use the pythagorean theorem to solve this: a^2 + b^2 = c^2.
You already have a and b which are 3 and 4. Square them up and you will get 9 + 16 = c^2.
Add.
25 = c^2
Lastly, square root both sides.
5 = c
The length of AB is 5.
