Which of the following is an X-intercept of the function f(X)=X^3-5X^2-8X+48

You have to searh the x values that make f(x) = 0

Factoring this equation is very difficult.

You can divide by x+3 and you will find that the equation can be factored as

(x+3)(x-4)^2

That means that x = -3 and x = 4 make f(x) = 0

Then the points are (-3,0) and (4,0).

The measure of angle A to the nearest tenth of a degree is: A 18.5 B 19.5 C 20.5

Andrew [12]

Answer:

B

Step-by-step explanation:

<u>This is a right triangle as shown by the right angle.</u>

The side opposite the right angle is the hypotenuse, which is 9.
The side opposite angle A is 3.

So we have the opposite of A and the hypotenuse.

The trigonometric ratio that relates opposite side to hypotenuse is SINE.

$sin\theta=\frac{opposite}{hypotenuse}$

Since, we need angle A, $\theta$ is A, opposite side is 3, and hypotenuse is 9, we substitute:

$sinA=\frac{3}{9}\\sinA=\frac{1}{3}$

<em>To solve for the angle, we use our calculator and find the inverse sin of $\frac{1}{3}$ :</em>

$A=sin^{-1}(\frac{1}{3})\\A=19.47$

<em>Rounding to nearest tenth of a degree:</em>

$A=19.5$

B is the right choice.
