$f(x) = -x^2-7x-6$

As $x \to \pm \infty$ , $y \to - \infty$ .

This can be easily verified by looking at the graph (graph of a quadratic equation).

The growth of a population is not linear, it's exponential.

31.

Exponential growth > polynomial, so $y = 3^x$ .

$V(t) = 30\cdot (25)^{\frac{t}{20}}$

The question is asking V(t) for t = 40.

$V(40) = 30\cdot (25)^{\frac{40}{20}} \\~\\V(40) = 30\cdot 25^2 \\~\\V(40) = 30\cdot 625 \\~\\V(40) = 18750$

36.

The point of symmetry of a quadratic equation $y = ax^2+bx+c$ is at its vertice:

$V_x = \dfrac{-b}{2a}$

$V_x = \dfrac{6}{2}$

$V_x = 3$

The line is x= 3.

The other leg is 12cm long.

Step-by-step explanation:

Given,

Hypotenuse = c = 15cm

One leg = a = 9cm

Other leg = b

As the triangle is right angled, therefore, using Pythagoras theorem;

$a^2+b^2=c^2\\(9)^2+b^2=(15)^2\\81+b^2=225\\b^2=225-81\\b^2=144\\$

Taking square root on both sides;

$\sqrt{b^2} =\sqrt{144} \\b=12\ cm$

The other leg is 12cm long.
