Answer:
12 cm³
Step-by-step explanation:
the volume of the sphere = 4/3 πr³
the volume of the cylinder (h=2r)= πr².2r
= 2πr³
the volume ratio of S : C =
4/3 πr³ : 2 πr³
= 4/3 : 2
= 4 : 6
= 2 : 3
so, the volume of the Sphere =
2/3 × 18 = 12 cm³
Answer:
2
Step-by-step explanation:
Hello
We can notice that

so 2 is one solution, we can put (x-2) in factor

So there is no other real solution.
Thanks
Y would equal 42 if you want to know what y is.
We are asked in the problem to determine the graph that represents the reflection of f(x) = 10^x. This function is an exponential function that is also asymptotic to the y axis. Asymptotic means that a function approaches a number at the x or y axis but not necessarily touching it. In this case, the function is asymptotic to y =0. The graph of f(x) = 10^x is attached on this answer. The reflection is simply taking f(-x) as we substitute -x to x. The resuting function is f(x)= 10 ^ -x. We can see from the graphs that they mirror each other at x = 0.
