I= sqrt (-1)
If the power is
- even then the value could be -1 or 1
-odd then the value could be -i or i
99 is odd so now is
-i if (99+1)/2 is even or is
i is (99+1)/2 is odd
Now check (99+1)/2= 100/2= 50,
50 is even so
i^99 = -i

Step-by-step explanation:
sin 66.4 = opposite side / hypotenuse
sin 66.4 = 21.3 / y
y = 21.3 / sin 66.4
y = 23.24.
tan 66.4 = 21.3 / x
x = 21.3 / tan 66.4
x = 9.31.

ok
Step-by-step explanation:
Answer:
1 or -9, depends on the problem, see below.
Step-by-step explanation:
-11--7+5
Two negatives make a positive so our new equation is:
-11+7+5
-11+7 is -4, so:
-4+5
And this leaves us with:
1
But I saw there was a parentheses, was it misplaced or was one not added? If one was not ended to the end, then the answer would be different.
(-11)-((-7)+5)
-7+5 is negative 2, so:
-11-(-2)
Once again, two negatives make a positive, so our new equation would be:
-11+2
Which gets us:
-9
