Answer:

Part A: See detail below.

Part B: Company B charges less than company A for 8 windows.

Part C: The saving using company B for 6 windows is $3.

Step-by-step explanation:

Part A:

Company A: (total charges) = ($6)x(N number of windows)+($12)

Company B: (total charges) = ($5)x(N number of windows)+($15)

Part B:

Company A for 8 windows: 6*8+12=$60

Company B for 8 windows: 5*8+15=$55

Part C:

(Saving) = (6*6+12)-(6*5+15)=48-45= $3

Eva deposited $30 in a savings account earning 10% interest, compounded annually.
alexdok [17]

Answer:

$ 9

Step-by-step explanation:

Simple Interest = P.R.T / 100

P = Principal (Amount invested) =$30

R = Rate= 10%

T = Time = 3 years

Therefore, Simple Interest (I):

I = PRT/100

I = ($30 * 10 * 3 ) / 100

I = $900 / 100

I = $9

She will have a total of $9 in three years

Which of the following is the graph of f(x)= 3 sin 2(x)?​
svetoff [14.1K]

Answer:

Step-by-step explanation:

Use the form  a sin ( bx- c) + d   to find the variables used to find the amplitude, period, phase shift, and vertical shift.

a = 3

b =  2

c  =  0

 d  =  0

Find the amplitude  |  a |

Amplitude:  3

Find the period using the formula  2π ÷ IbI

Period:  π

Find the phase shift using the formula  \frac{c}{b}

Phase Shift:  0

Find the vertical shift  : d

Vertical Shift:  0

List the properties of the trigonometric function.

Amplitude:  3

Period:  π

Phase Shift:  0  ( 0  to the right)

Vertical Shift:  0

Select a few points to graph.

x                       f ( x )

0                        0

π ÷ 4                 3

π  ÷ 2                 0

3 π  ÷ 4              -3

π                         0

 The Trignometric  function can be graphed using the amplitude, period, phase shift, vertical shift, and the points.

Amplitude:  3

Period:  π

Phase Shift:  0  ( 0  to the right)

Vertical Shift:  0

x                       f ( x )

0                        0

π ÷ 4                 3

π  ÷ 2                 0

3 π  ÷ 4              -3

π                         0
