Answer:
|A| - C = 5
Step-by-step explanation:
The maximum value that a sine function can have is 1, and the minimum value is -1.
With this information, to find the minimum value of y, we can use sin(Bx) = -1, and to find the maximum value, we can use sin(Bx) = 1. Then, we have that:
19 = A + C
-5 = -A + C
Summing both equations, we have:
14 = 2C
C = 7
Now, to find the value of A, we can use the first equation:
19 = A + C
19 = A + 7
A = 12
So the value of |A| - C is:
|12| - 7 = 12 - 7 = 5
Yes，y＝2x＋7 is a function
because x is argument，and it has x and y，it is a primary function
Answer: n=-4
Step-by-step explanation:
The empirical rule for a normal distribution states that 95% of the data points lie within plus and minus two standard deviations from the mean. 30 is two standard deviations below the mean and 42 is two standard deviations above the mean.
Therefore, 95% if the employees are between 30 and 42 years old.
