Answer:
1
Step-by-step explanation:
First find f(0) and g(0). These are the values where x=0 in each function.
f(0) = 1+0 = 1
g(0) = 1^2 - 1 = 1-1 = 0
So f(0) = 1 and g(0) = 0.
Now substitute f(0) = 1 into g(t).
g(1) = 1^2 -1 = 1-1 = 0.
So g(f(0)) = 0.
Now substitute g(0) = 0 into f(t).
f(0) = 1 + 0 = 1.
So f(g(0)) = 1.
Add the values 0 and 1 to get 0+1 = 1.
F = ma
the question said, F and M both are doubled ,so,
2F =2ma
but you can see the result is same !!
so acceleration doesn't change !! so final acceleration is also 2.2 !!
Answer:
The volume of this sphere =
Step-by-step explanation:
The region enclosed by the semicircle is revolved completely around the x-axis . Then the solid formed is a sphere of the same radius as that of the semicircle. We have to find the volume of this sphere. If the semicircle had center at the origin then the sphere also has the center at the origin.
Let the radius of given circle = r
Surface area of this sphere =
The volume of this sphere =
This is the volume of the required solid.

Answer:
d. (16/24) * 100%
Step-by-step explanation:
The infection rate =( Number of infected people/ total number of people) * 100%
After the end of round 3
Infection rate = (8/24)*100%
After the end of round 4, since no one is infected more than once
Infection rate = 2* (8/24)*100%
Infection rate = (16/24) * 100%
