Answer:
the radius would be half of 45 so if you half it i think it would be 22.5 but someone correct me if im wrong
Step-by-step explanation:
have a good day

Recall the half-angle identity:

So in order to find

, we only need to know the value of

. But there are two possible values. To decide which to take, we use the given information: we know that

lies in quadrant III, which means

, so

, which places

in quadrant II. In this quadrant, the sine of angle is positive, and so


is an angle of a ray whose terminal point,

lies on the circle

. The

-coordinate is all we need to know in order to find that

. So,
Answer:
always negative
Step-by-step explanation:
for example -3*2 = -6
Answer:
6xrx7
2
Regroup terms.
6x{x}^{7}r6xx7r
3
Use Product Rule: {x}^{a}{x}^{b}={x}^{a+b}xaxb=xa+b.
6{x}^{1+7}r6x1+7r
4
Simplify 1+71+7 to 88.
6{x}^{8}r6x8r
