What are the coordinates of the terminal point for 0=330
Ira Lisetskai [31]

Answer: Option C.

Step-by-step explanation:

The coordinates (x,y) of a terminal point for an angle θ are:

x = cos(θ) and y = sin(θ).

In this case, we have θ = 330°.

Then we have:

x = cos(330°) = 0.866 = (√3)/2

y = sin(330°) = -0.5 = -1/2

then the coordinates of the terminal point are ((√3)/2, -1/2)

Then the correct option is c.

Simplify the expression <br><br> 6(-5n + 7)
Hunter-Best [27]

6(-5n+7)=0


We simplify the equation to the form, which is simple to understand

6(-5n+7)=0


Reorder the terms in parentheses

+(-30n+42)=0


Remove unnecessary parentheses

-30n+42=0


We move all terms containing n to the left and all other terms to the right.

-30n=0-42


We simplify left and right side of the equation.

-30n=-42


We divide both sides of the equation by -30 to get n.

n=1.4

Hope this helps!
