If  i = √-1 ,

then ...

i²  =  (√-1)²  =  -1

i³  =  - √-1  =  -i          <== the answer to the question

i⁴  =  (i²) · (i²)  =  (-1) · (-1)  =  1

and then the whole thing starts over again, for higher powers of  i .

Answer:

Your slope would be -1/10

Step-by-step explanation:

To find the slope from two points, you would use the formula y2-y1/x2-x1

In this case, the equation would look like -4-(-3)/5-(-5)

-4 - (-3) = -1

5 - (-5) = 10

-1/10 = -1/10

Wouldn’t it just be 94 degrees? please help
nataly862011 [7]

We know that the m<RTV = 65°.

If we know that the m<UTV = 29°, we can simply

subtract the m<UTV from the m<RTV to get the answer.

So we have 65 - 29 or 36°.
