Factors are (3x + 5) and (x - 2). Zeros are -5/3 and 2.

Step-by-step explanation:

Step 1: Given quadratic equation 3x² - x = 10 ⇒ 3x² - x - 10 = 0

Step 2: Use factoring method (product and sum rule) to find factors and zeros. So the equation can be written as below.

⇒ 3x² - 6x + 5x - 10 = 0

⇒ 3x(x - 2) + 5(x - 2) = 0

⇒ (3x + 5)(x - 2) = 0 These are the factors of the equation.

Step 3: Find zeros by equating the factors to 0.

⇒ 3x + 5 = 0 and x - 2 = 0

⇒ x = -5/3 and 2

Which trigonometric function requires a domain restriction of [-pi/2, pi/2] to make it invertable?

Galina-37 [17]

Answer:

$y=\tan x$

Step-by-step explanation:

The trigonometric function that needs a domain restriction of $[-\frac{\pi}{2},\frac{\pi}{2} ]$ to make it invertible is $y=\tan x$ .

The function $y=\tan x$ will pass the horizontal line test on this interval therefore making it an invertible function on this interval.

This explains why the inverse tangent function, $y=\tan^{-1} x$ has range $[-\frac{\pi}{2},\frac{\pi}{2} ]$ .

What is the slope of this line?<br> It has the points of (-8,2) (0,2) and (7,2)

tresset_1 [31]

Answer:

Well the slope would be 0 because the y doesn't change. So if y is same it is 0, if x remains the same Slope is undefined, and then there is normal slope.

svp [43]

Answer:

Step-by-step explanation:

(3x - 3)(x^2 + 3) = 3x^3 + 9x - 3x^2 - 9

3x^3 = 3x^2 + 9x - 9

answer is C
