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

P = P_0 e^{-rt}

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.

What value in place of the question mark makes the polynomial below a perfect square trinomial ?
gregori [183]

Answer:

Option D is correct.

Step-by-step explanation:

We have been given x^2+22x+?

We need to tell which one of them will give the perfect square trinomial.

Trinomial is the polynomial with three terms.

x^2+22x+121

If we factorize it by middle term splitting we get:

x^2+11x+11x+121

\Rightarrow x(x+11)+11(x+11)

\Rightarrow (x+11)(x+11)

\Rightarrow (x+11)^2  is the perfect square trinomial.

Therefore, option D is correct

The perimeter of an equilateral triangle is 11 inches more than the perimeter of a square, and the side of the triangle is 6 inc
uysha [10]

Answer:

13 inches

Step-by-step explanation:

Let P(t) and P(s) be the perimeters of the equilateral triangle and square respectively. Similarly, t and s be the side lengths of equilateral triangle and square respectively.

According to the first condition :

(Perimeter of an equilateral triangle is 11 inches more than the perimeter of a square)

\implies P(t) = P(s) + 11

\implies 3t = 4s + 11....(1)

According to the second condition :

(The side of the triangle is 6 inches longer than the side of the square)

\implies t = s + 6....(2)

From equations (1) & (2)

3(s + 6) = 4s + 11

3s + 18 = 4s + 11

3s - 4s = 11 - 18

-s = - 7

s = 7 inches

\because t = s + 6

\because t = 7 + 6

\because t = 13\: inches

Thus the side of the triangle is 13 inches long.
