Answer:
B
Step-by-step explanation:
Given a sinusoidal function in the form , we can say:
From the function given m(t) = 7 Cos (t+3), we see that
A = 7
B = 1
C = 3
D = 0
Thus, from the info, we can say
Amplitude = 7
Period = 2π
Phase Shift = -3
Vertical Shift = 0
Answer choice B is right.
Answer:
9, 11 and 19
Step-by-step explanation:
the first two integers I've picked are 19 and 9 because it gives a range of 10 and is less than 25
the range is the bigger number - smaller number
19 - 9 = 10
to find the third number we are given mean = 13
the third number = x
multiply both sides by 3 to get rid of the fraction
subtract both sides by 28
the third number is 11
the three integers are 9, 11 and 19
there are two other possible answers:
8, 13 and 18
7, 15 and 17
