Answer:
The answer is 10
Step-by-step explanation:
a + 5 =15
15-5=10
P(A) = P(8) + P(9) + P(10) = 3/10 so P(A complement) = 1 - P(A) = 1 - 3/10 = 7/10 - D
Answer:
-78
Step-by-step explanation:
4 Months is -312 so dividing by 4 will give the decrease of one month:
-312 ÷ 4 = -78
X is greater than or equal to negative 1 and you would right 1 comma infinity
So, the function is obviously shifted up by 1 so it rules out A and B, and we also see that the period is 4pi rather than 2pi, and using the fact that:
Now that we know our b value, we see that the correct answer would be C.
