Which function represents g(x), a reflection of f(x) = (3)x across the y-axis?g(x) = 2(3)x
g(x) = −(3)x
g(x) = (3)−x
g(x) = 2(3)−

Answers

Answer: g(x)=(3)^(-x)

Step-by-step explanation:

We know that if a figure is reflected across y axis then its y coordinate remains same but the x coordinate changes its polarity.

i.e. the function f(x) will become f(-x) .

Now, the given function :f(x)=(3)^x

Then , after reflection across y axis the new function will become:

g(x)=f(-x)=(3)^(-x)

A sphere has a radius of 9 feet. A second sphere has a radius of 6 feet. What is the difference of the volumes of the spheres?

Answers

Well the formula to find the volume of a sphere is 3/4(pi)r^3
sphere with the radius of 9: 3/4(pi)9^3 = 3053.63
sphere with the radius of 6: 3/4(pi)6^3 = 904.78
the difference: 2148.85
Difference of the volumes of the spheres=volume greater sphere - volume smaller sphere.

Volume of a sphere=(4/3)πr³

Difference of the volumes of the spheres=(4/3)πr₁³ - (4/3)πr₂³=(4/3)π(r₁³-r₂³)

Data:
r₁=9 ft
r₂=6 ft

then :

Difference of the volumes of the spheres=4/3π[(9 ft)³ - (6 ft)³]=(4/3)π(513 ft³)=
≈2148.85 ft³.


Answer: 2148.85 ft³
