I^32 = (i^4)^8 and i^4 = 1
so (i^4)^8 =1^8 = 1
The trick on all questions like this is to get as many i^4’s out of the way, since they’re all just 1s.
Answer:
c= 14
Step-by-step explanation:
hope this helps
Subtraction is the opposite of addition. eg. 9+5=14 but 14-5=9
You mix the letters A, C, Q, U, A, I, N, T, A, N, C, and E thoroughly. Without looking, you select one letter. Find P(Q or C) as

Answer:
P(Q or C) = 0.25
Step-by-step explanation:
We are given the following in the question:
Letters:
A, C, Q, U, A, I, N, T, A, N, C, E
Total number of observations, n = 12
We have to find the probability that a randomly selected letter is Q or C.
Formula:
P(Q or C) =
Thus,
P(Q or C) = 0.25
Answer:
There are 5 turning points at x = -3, -1.11, 0, 1.44 and 4.
Step-by-step explanation:
The product rule for 3 terms is
F' (x) = f'(x) g(x) h(x) + f(x) g'(x) h(x) + f(x) g(x) h'(x)
F(x) = x^2(x - 4)^7 (x + 3)^6
F' (x) = 2x(x-4)^7(x+3)^6 + x^2 7(x - 4)^6 (x + 3)^6 + x^2(x-4)^7 6(x+3)^5 = 0 at the turning points.
That is some equation!!
By observation, 3 roots are x = 0 , x = 4 and x = -3 so there are turning points at these values of x.
I'll use software to graph it to find any more real solutions - they are -1.11 and 1.44 to nearest hundredth.
