<u>Solution</u><u>:</u>
- When, you rotate a picture by 180°, we rotate it by half of a full circle.
- The first picture is the original picture.
- The second picture is the image when it is rotated by 90°.
- The third picture is the images when, it is rotated once more by 90°. This image is the rotation of the image around P by 180°.
- So, the answer will be option A.

Answer:
15
Step-by-step explanation:
8+5=13
39/13=3
3*8=24(boys)
3*5=15(girls)
What so you need to know?
To find concavity we need to find the second derivative.
Use quotient rule to find f'(x)=4/(x+3)^2
Then use chain rule to find f''(x)=-8/(x+3)^3
To find potential inflection points, we need to find all x values where the second derivative is equal to 0 or is undefined.
Set the numerator and denominator equal to 0 and solve.
(x+3)^3=0
x+3=0
x= -3
Now plug a value less than -3 and greater than -3 into the second derivative to find where the concavity is upward (positive number).
Since f''(-4) is positive, that means that f(x) is concave up on the interval (-infinity, -3).
