Answer D.

Insert (2, 2) in for x and y in the equations.

2(2)+ 3(2) = ?
? = 10

Recall the scenario about Eric's weekly wages in the lesson practice section. Eric's boss have been very impressed with his work
Alona [7]

Answer:  

1)\quad f(x)=\bigg\{\begin{array}{ll}12x&0\leq x

2) D: x = [0, 24]

3) R: y = [0, 384]

4) see graph

<u>Step-by-step explanation:</u>

Eric's regular wage is $12 per hour for all hours less than 9 hours.

The minimum number of hours Eric can work each day is 0.

f(x) = 12x    for   0 ≤ x < 9

Eric's overtime wage is $18 per hour for 9 hours and greater.

The maximum number of hours Eric can work each day is 24 (because there are only 24 hours in a day).

f(x) = 18(x - 8) + 12(8)

    = 18x - 144 + 96

    = 18x - 48           for 9 ≤ x ≤ 24

The daily wage where x represents the number of hours worked can be displayed in function format as follows:

f(x)=\bigg\{\begin{array}{ll}12x&0\leq x

2) Domain represents the x-values (number of hours Eric can work).

The minimum hours he can work in one day is 0 and the maximum he can work in one day is 24.

D:  0 ≤ x ≤ 24        →        D: x = [0, 24]

3) Range represents the y-values (wage Eric will earn).

Eric's wage depends on the number of hours he works. Use the Domain (given above) to find the wage.

The minimum hours he can work in one day is 0.

f(x) = 12x

f(0) = 12(0)

     =  0

The maximum hours he can work in one day is 24 <em>(although unlikely, it is theoretically possible).</em>

f(x) = 18x - 48

f(24) = 18(24) - 48

       = 432 - 48

       = 384

D:  0 ≤ y ≤ 384        →        D: x = [0, 384]

4) see graph.

Notice that there is an open dot at x = 9 for f(x) = 12x

and a closed dot at x = 9 for f(x) = 18x - 48

360 words in 1/12 hour. Second try 360 words in 1/15 hour. Was he faster or slower second attempt
xxTIMURxx [149]

Answer:

Second Attempt is faster.

Step-by-step explanation:

He reads 360 words in \frac{1}{12} hour in the first attempt and in the second attempt he reads the same number of words in \frac{1}{15} hour.

Since, $ \frac{1}{15} < \frac{1}{12} $ he takes less time in the second time. Less time means the work is done faster.

Therefore, second attempt is faster.

The next five sequence based on the information about the square will be 36, 49, 64, 81 and 100.

<h3>How to illustrate the information?</h3>

From the information, it was stated that an ancient culture labeled certain numbers as square numbers and that the numbers 1, 4, 9, 16, 25, and so on are square numbers.

It should be noted that the number given are squares of 1,2,3...

Therefore, the next five sequence will be:

6 × 6 = 36

7 × 7 = 49

8 × 8 = 64.

9 × 9 = 81

10 × 10 = 100
