Form a sequence that has two arithmetic means between -1 and 59.
9966 [12]

Answer:

Correct choice is B

Step-by-step explanation:

For the numbers -1 and 59, find the difference 59-(-1):

since 59-(-1)=60 and \dfrac{60}{3}=20 (two arithmetic means tells you there will be three intervals), two arithmetic means will be

  • -1+20=19;
  • 19+20=39.

The only correct sequence is -1, 19, 39, 59.

To quickly solve this problem, we can use a graphing tool or a calculator to plot each equation.

Please see the attached image below, to find more information about the graph

s

The equations are:

1) y = sin (3x + π/6)

2) y = cos (3x - π/6)

3) y = cos (3x - π/3)

Looking at the graphs, we can see that the identical ones

are equations one and three
