Answer:
Step-by-step explanation:
Given that initial population is 3100
The population is decreasing continuously which means the population at any time t can be represented by the funciton
where t = time and r = rate
The population is continuously decreasing at the rate of r% per unit of time.
When t becomes very large,
we get limit would be P0 (0) =0
The population will decrease and almost tend to 0 as time advances.
There is no chance for further decrease as population cannot be negative
So limiting population is 0.
First observe that if ,
Let and . It follows that
Now let , so . Solving for ,
which means
Now solve for .
(note that we assume )
(we omit since is not true)
Angle A C would be collect
Y as function of x
y=f(x)
that just means y=-2x+3
that is form y=mx+b
m=slope
b=y intercept
so then
y=-2x+3
the y intercept is 3 so go up 3 units on the y axis from the center (0,0) and put a point there
the slope is -2
so slope is rise/run
rise/run=-2=-2/1
so go down 1 units and go right 1 unit
put another point there
we get the opints (0,3) and (1,1)
connect them
see graph below
If 110 students play both
The 300 that play volleyball includes them.
That’s mean that 190 (300-110) play only volleyball
Also (the same) 200 play cricket, so only cricket play 90 students (200-110)
Answer: either volleyball or cricket is
(300-110)+(200-110) = 190+ 90 = 280
Answer: 280
