This is for the one with the green background :) I corrected a few of the errors that collided with the answers for the 3 qns you didn’t know. Hope this helps!!!
Answer:
C.
Step-by-step explanation:
So, here's what you need to remember:
If we have a function <em>f(x)</em> and a factor <em>k</em>:
<em>k(f(x)) </em>will be a vertical stretch if k is greater than 1, and a vertical compression if k is greater than zero but less than 1.
<em>f(kx) </em>will be a horizontal compression if k is greater than 1, and a horizontal stretch if k is greater than zero but less than 1.
We are multiplying 0.5 to the function. In other words: 0.5f(x).
This is outside the function, so it's vertical.
0.5 is less than 1, so this would be a vertical compression
The anwser is ~27
Step 1: Area Of Half Triangle((3 * 4) / 2)
Step 2: Are Of Full Traingle(6 * 2)
Step 3: Get Are Of Sphere(3pi^2)
Step 4: Get Half-Sphere((3pi^2)/2)
Step 5: Sum Up(12 + 3pi^2/2)
Step 6: Simplify(12 + ~15 = 27)
Divide by three on both sides then end up with x+2=3 then x=1
2,3,5,6.
1 and 4 is not the same as the expression given.
