Use the equation r =2.1x^2 -14.3x +35, where x is the number of years after 2000, to determine the revenue from the sales of U.S
xxMikexx [17]

Answer:

Step-by-step explanation:

Given that:

r = 2.1x^2 - 14.3x + 35

For year 2000; x = 0

So; r (0) = 2.1(0)^2 - 14.3(0) + 35

r (0) =  35

For year 2001; x = 1

r (1) = 2.1(1)^2 - 14.3(1) + 35

r (1) =22.8

For year 2002; x = 2

r (2) = 2.1(2)^2 - 14.3(2) + 35

r (2) = 14.8

For year 2003; x = 3

r (3) = 2.1(3)^2 - 14.3(3) + 35

r (3) = 11

For year 2005; x = 5

r (5) = 2.1(5)^2 - 14.3(5) + 35

r(5) = 16

For year 2010; x = 10

r (10) = 2.1(10)^2 - 14.3(10) + 35

r(10) = 102

For year 2018; x =18

r(18) = 2.1(18)^2 - 14.3 (18) + 35

r(18) = 458

Thus, the table can be presented as seen below.

Year      2000     2001     2002     2003     2005     2010     2018

x               0             1             2            3           5            10         18

r(x)          35          22.8        14.8        11            16         102      458

SO, we will notice that the revenue for the albums starts decreasing and when it reaches the minimum, it started increasing with increasing x.

The attribute behind this trend is because the revenue function r(x) typically implies that it is a quadratic function.

How to solve 16 * 12.5
Mariana [72]

Answer: 200

Step-by-step explanation:

First I would do it like this.

12.5

X. 16

—————-

6 times 5 is 0, carry the 3, 6 times 2 is 12 and add 3 from the other which is 15, put the 1 from the 15 to the one next to the 12. 6 times 1 is 6 plus 1 is 7 which now you have 750. 5 times 1 is 5, 2 times 1 is 2, 1 times 1 is 1. It should look like this now.

12.5

X 16

—————

750

+ 1250

——————-

Which is 8750 but wait. Where is the decimal? Well, there is only one number behind the decimal so it is 875.0 or 875.

Solve the inequality.
nataly862011 [7]

Answer:

D

Step-by-step explanation:

4x + 3 < 3x + 6 ( subtract 3x from both sides )

x + 3 < 6 ( subtract 3 from both sides )

x < 3 → D
