Answer:

x = ± 4

Step-by-step explanation:

Given

x² = 16 ( take the square root of both sides )

x = ± \sqrt{16} = ± 4

That is x = - 4, x = 4

Rock musician Donny West is paid 15% on his CD sales and tour video sales. Last year, he sold one million CDs and 550,000 videos
Likurg_2 [28]

Answer:

Total amount of CD sales was $750,000.

Step-by-step explanation:

one million CDs were sold at $5/CD.

1,000,000 × $5 = $5,000,000

Donny gets 15% of the sales, so he'll receive the amount of CD sales as:

$5,000,000 × 15/100 = $50,000 × 15 = $750,000.

Optional:

If you add both of the multiplied values, 1,000,000 × 5 + 550,000 × 6

= $5,000,000 + $3,300,000

= $8,300,000

so, 15% of it would be $1,245,000.

if you calculate both separately and then add them, you'll still get $1,245,000.

I hope this'll help.

Answer:

Please check the explanation!

Step-by-step explanation:

Finding the slope:

Taking two points to find the slope of the linear function

  • (2, 10)
  • (3, 13)

Slope = m = y₂-y₁ / x₂-x₁

                 = (13-10) / (3-2)

                 = 3 / 1

                 = 3

Thus, the slope = m = 3

Finding the common difference between consecutive terms of the arithmetic sequence

Given the sequence

10, 13, 16, 19

d = 13-10=3,  d=16-13=3,  d=19-16=3

Thus, the common difference between consecutive terms of the arithmetic sequence is:

d = 3

Finding the difference between the terms a₂ and a₄

a₂ = 13

a₄ = 19

The common difference between a₂ and a₄ = 19 - 13

                                                                         = 6

Thus, the common difference between a₂ and a₄ = 6

Find the common difference of the Arithmetic Sequence

Given the sequence

10, 13, 16, 19

d = 13-10=3,  d=16-13=3,  d=19-16=3

As the common difference between all the adjacent terms is the same. Thus, the common difference of the Arithmetic will be: d = 3

<u>RESULT </u>

From the above calculations, we conclude that:

  • Slope =  3
  • The common difference between consecutive terms of the arithmetic sequence = 3
  • The difference between the terms a₂ and a₄ = 6
  • The common difference of the Arithmetic Sequence = 6

Thus,

The answer to the ''different'' question is: 6

The answer to the ''same'' three questions: 3
