Hello:
-1 ≤ sin(x- π ) ≤ 1
-2 ≤ 2 sin(x- π ) ≤2
1-2 ≤ 1+ 2 sin(x- π ) ≤ 1 +2
-1≤y≤3
the range is : <span>[-1 : 3 ]</span>
2.4 this is what I got when I put it in the calculator
Answer:brainliest plsssss
Step-by-step explanation:
1/2x+15=x
X+30=2x
30=2x-x
30=x
Number of girls in class
30-12=18
☆ the number of girls in his class are 18
For better understanding think of it this way. There are hundred customers, 60 orders coffee 35 orders pie and 30 does not order pie or coffee.
This means that 70 does order coffee or pie or both. Out of those 70 people 10 will not order coffee and 35 will not order pie. Thus 70-10-35=25 will order both coffee and pie.

An exponential function can either represent a growth or decay.
- The price of fuel A is increasing.
- Fuel B recorded a greater percentage change in price
<u>Part A</u>
For fuel A, the exponential function is given as:

An exponential function is represented as:

Where b represents the rate.
By comparison

Since b (i.e. 1.04) is greater than 1, then the price of fuel A is increasing.
<u>Part B</u>
The table represents an exponential function.
The rate of fuel B is calculated by dividing the current price by the immediate previous price.
So, we have:


By comparison, 1.06 is greater than 1.04 (the rate of fuel A).
Hence, fuel B recorded a greater percentage change in price
