Answer:
Yes, F is a continuous function of r
Step-by-step explanation:
We are given that
When r<R
Where M=Mass of the earth
R=Radius of earth
G=Gravitational constant
We have to find the function is continuous of r or not.
LHL
RHL
When a function is continuous at x=a
Then, LHL=RHL=f(a)
RHL==LHL=F(R)
Hence, the function is continuous of r.
Answer: B and F
Step-by-step explanation:
Since, In the first case original amount = 45
So, the increasing percentage when the original amount increases to 75,
= %
In second case original amount = 75
So the decreasing percentage when the original amount decreases to 45,
= %
Thus, We found that the ratio of the percent increase is not the same as the percent decrease ( because,
Also, The original amount of the present increase is different from the original amount for the persons decrease. ( Because,
Therefore, Option B and F is correct only.
