astra-53 [7]

Using the law of sins:

B =sin^−1((sin(A)⋅a)/b) = sin^−1((sin(65)⋅110)/155)=40.03 degrees

B= 40.03 degrees (round as needed)

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

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

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

30.

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

31.

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

35.

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

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.
