Answer:0.175 m/s
Step-by-step explanation:
Given
Two sides of length 9 and 13 m
angle between them is increasing at an angle of 0.02 rad/min
rate of increasing of third at
let a=9
b=13
c=unknown side
Now using cos rule of triangle
Differentiating both sides we get
at
c=11.53 m
substituting values we get
We know that the number of users triple each day
Let number of users on day 1 be x
⇒ Users on day 2 = = 3x
and Users on day 3 = = 9x
And so on...
% Increase in users from day 1 to day 2 =
⇒ % Increase in users from day 1 to day 2 =
⇒ % Increase in users from day 1 to day 2 =
⇒ % Increase in users from day 1 to day 2 = 200%
Similarly,
% Increase in users from day 2 to day 3 =
⇒ % Increase in users from day 2 to day 3 =
⇒ % Increase in users from day 2 to day 3 =
⇒ % Increase in users from day 2 to day 3 = 200%
Hence, we can see that the percentage increase each day is 200%
