Answer:
C. -36
Step-by-step explanation:
(-9)(-8) ÷ (-2)
C. -36
With the given order of integration, the interval over D is
![\displaystyle \iiint_D f(x,y,z) \, dV = \int_{-3}^{3} \int_{-\sqrt{9-x^2}}^{\sqrt{9-x^2}} \int_{-\sqrt{9-x^2-z^2}}^{\sqrt{9-x^2-z^2}} f(x,y,z) \, dy \, dz \, dx](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Ciiint_D%20f%28x%2Cy%2Cz%29%20%5C%2C%20dV%20%3D%20%5Cint_%7B-3%7D%5E%7B3%7D%20%5Cint_%7B-%5Csqrt%7B9-x%5E2%7D%7D%5E%7B%5Csqrt%7B9-x%5E2%7D%7D%20%5Cint_%7B-%5Csqrt%7B9-x%5E2-z%5E2%7D%7D%5E%7B%5Csqrt%7B9-x%5E2-z%5E2%7D%7D%20f%28x%2Cy%2Cz%29%20%5C%2C%20dy%20%5C%2C%20dz%20%5C%2C%20dx)
X=6
g(f(x))=g(f(18))
=g(5/6*18 +5)
=g(20)
=(5*20)+6
=106
Answer is “D” I took the test my self
X seniors/1000 total seniors=63/100
x would turn out to be 630 :)
