Answer:
should be 3^X = 7 and X = log7/log3
Step-by-step explanation:
Given:
Radius of the circle = 10 in
Central angle of the sector = 45 degrees
To find:
The area of the sector.
Solution:
Area of a sector is
Where, 
is the central angle in degrees.
Putting r=10 and 
, we get
Therefore, the area of the sector is 12.5π sq. inches.
Hello,
In the picture, i have draw one translation 
and a line symmetry 
You have just to follow the colors.
1) Company A and C
2)Your answer is f(t) = 180(0.5)^t This is because the number is cut in half for every hour.
3)C 0 ≤ x ≤ 50 is the right answer because the starting time 9:05 is considered as zero and the 9:55 is the ending point which is considered as 50.Or simply the difference of both the times is the domain of the function.

Answer:</h3>
The Area of the tray ≈380 cm
<h3>
Solution:</h3>
- We are given the diameter of the tray, which is equivalent to 22 cm.
- We are asked to find the area of the tray.
- Remember the formula:
- Area of a circle = πr²
- Where
- π -> pi (3.14...)
- r -> radius
- Notice that we aren't given the radius. We're given the diameter only.
- No reason to panic. We can easily find the radius by dividing the diameter by 2.
- The radius is equal to 11 cm.
- Now, plug the values into the formula:
- A=π(11)²
- A=121π
- A≈380 cm
Hope it helps.
