Step-by-step explanation:
Answer:
81π
Step-by-step explanation:
-The sum of central angles in a circle add up to 360°.
-Let x be the area of the circle.
-Given the area of a 120° is 27π, the circles area can be calculated as:

Hence, the area of the circle is 81π
For this case we have an exponential equation of the form:

Where,
- <em>A: initial value
</em>
- <em>b: decrease rate
</em>
- <em>x: number of years
</em>
Substituting values in the given equation we have:

Answer:
The value of the car after 15 days is given by:

Answer:
6x+50
Step-by-step explanation:
5(x+10)+x=5x+50+x=6x+50
Hope this is simple enough!
