What is the equation of the midline of the graph of y=2cos(x/4)−3

y = -3

Step-by-step explanation:

y=2cos(x/4)−3

range of cos α : -1 ≤ cos α ≤ 1

-2 ≤ 2cos(x/4) ≤ 2

-5 ≤ 2cos(x/4)−3 ≤ -1       (-2-3= -5 and 2-3= -1) ....Range ( 2 x Amplitude)

midline: midline of y = -1 and y = -5        y = -3

22

step-by-step explanation:

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
