If the point (x, square root 3/2) is on the unit circle, what is x?

Answer:

$\frac{1}{2}$

Step-by-step explanation:

On a unit circle, the only points where y = $\frac{\sqrt{3} }{2}$ have an x coordinate of $\frac{1}{2}$ or $\frac{-1}{2}$ . Since only one of those is an option, the answer is $\frac{1}{2}$ .

the equation of line cd is y = 3x − 3. write an equation of a line perpendicular to line cd in slope-intercept form that contain

liberstina [14]

Answer:

The required equation is $y=-\frac{1}{3}x+2$ .

Step-by-step explanation:

The equation of line cd is

$y=3x-3$

Slope intercept form of a line is

$y=mx+b$

Where, m is slope and b is y-intercept.

Slope of line cd is 3.

The product of slopes of two perpendicular lines is -1.

$m_1\times m_2=-1$

$3\times m_2=-1$

$m_2=-\frac{1}{3}$

Therefore slope of perpendicular line is $-\frac{1}{3}$ .

Point slope form of a line is

$y-y_1=m(x-x_1)$

Slope of perpendicular line is $-\frac{1}{3}$ and line passing through the point (3,1).

$y-1=-\frac{1}{3}(x-3)$

$y=-\frac{1}{3}x+1+1$

$y=-\frac{1}{3}x+2$

Therefore the required equation is $y=-\frac{1}{3}x+2$ .

10. What makes an equation a quadratic?

CaHeK987 [17]

Answer:

D. The equation has a variable multiplied by itself. A squared variable.

Step-by-step explanation:

A quadratic equation will always start with a term being squared. For example, $8x^{2}$ + 5x + 7 = 44. Another example would be $4x^{2}$ + 2x - 10 = 12. These are just random numbers, but the equation will always look the same! Hope this helps!
