Step-by-step explanation:

Rewrite csc(x) in terms of sin

Multiply the numerator. Notice that the factors in the numerator are reciprocal so they will factor out to 1.

Notice that cotangent and tan are reciprocal so

Answer:
the first one
Step-by-step explanation:
distribution
Answer:
See below.
Step-by-step explanation:
The law of sines is usually written as a / sin A = b / sin b == c / sin C where a is the side opposite angle A ,etc.
The first equation is true because it is obtained by cross multiplying
a / sin A = b / sin B, therefore b sin A = a sin B.
The second one is not true.
The third and fourth are both true.
I believe the fastest way to solve this problem is to take any two of the given points and to find the slope and y-intercept of the line connecting those two points.
Let's choose the 2 given points (-3,16) and (-1,12).
Going from the first point to the second, the increase in x is 2 and the increase in y is actually a decrease: -4. Thus, the slope of the line connecting these two points is m = -4/2, or m = -2.
Now use the slope-intercept formula to find the y-intercept, b.
One point on the line is (-3,16), and the slope is m = -2.
Thus, the slope-intercept formula y = mx + b becomes 16 = -2(-3) + b.
Here, b comes out to 10.
So now we have the slope and the y-intercept. Write the equation:
y = mx + b becomes y=-2x+10. Which of the four given answer choices is the correct one?
1-2 is right
3 you have to draw a shape and then put 3 lines then shade in one
number 4 you have to draw a shape again but put 8 lines through then shade 1
5 your answer is 1/8
6 your answer is 1/4
7 you have to draw a shape again draw 3 line in the shape then shade 1 and your fraction is 1/3
