Answer:

Step-by-step explanation:

6/2=3 cm is the radius V(4/3πr³) = 4/3.π.27…(1)

8/2= 4 cm is the radius and V = 4/3.π.64…..(2)

10/2=5 cm is the radius and V = 4/3.π.125…(3)

The Total Volume is the addition of (1)+(2)+(3) or 4/3π (27+64+125) or New volume is 4/3.π.(216) cm³ and therefore...

The radius of the New Solid Sphere is Cube Root of 216 (r³) = √6.6.6 or r = 6 cm and the diameter is 6.2 = 12 cms.

12 cms answer. Brainlist please?

If you apply the changes below to the absolute value parent function, F(x)=|x|, what is the equation of the new function? Shift

Nina [5.8K]

The transformation that shifts a function along the $x-axis$ is $f(x+a)$ , which shifts the function to the left, and $f(x-a)$ , which shifts the function to the right.

The transformation that shifts a function along the $y-axis$ is $f(x)+a$ , which shifts the function up, and $f(x)-a$ , which shifts the function down

Hence, the correct answer is D: $g(x)=f(x+8)-3$
