The measure of angle θ is 3pi/2. The measure of its reference angle is pi /,

1 answer:

6 0

I know for a fact that the reference angle for 3pi/2 is pi/2 so the first one is A, and if I'm not mistaken, the second one should be undefined. I'm not sure about the second one.

What is the slope of a line that is perpendicular to the line represented by the equation y=3/4x-1/2?

kherson [118]

The answer is: " - (4/3) " .
____________________________________
Explanation:
____________________________________
The original equation given has a slope of (3/4).

Note: We know this since the equation for the slope of the line is written in "slope-intercept form" ; also known as: "point-slope form"; that is:

" y = mx + b " ; in which "m" (the coefficient of "x") is the slope.
____________________________________________________
The slope of a line PERPENDICULAR to an equation, when written in "slope-intercept form", is the "negative reciprocal" of the slope of the original line.

Hence, the negative reciprocal of "(3/4)" is: "-(4/3)" .

Which equations are true for x = –2 and x = 2? Check all that apply.

Katyanochek1 [597]

Hi Brainiac

x² - 4 = 0

Add 4 to both sides

x² - 4 + 4 = 0 + 4

x² = 4

Now take the square root

x= +/-√4

x= 2 or x= -2

The answer is A

I hope that's help :)
