R(x)=2square root of x S(x)= square root of x (rs)(4)=

Mathematics
1 answer:
Deffense [45]3 years ago
5 0

Answer:

(rs)(4) = 8

Step-by-step explanation:

Given

r(x) = 2\sqrt{x

s(x) = \sqrt x

Required

Determine (rs)(4)

In functions:

(fg)(x) = f(x) * g(x)

This implies that:

(rs)(x) = r(x) * s(x)

Substitute values for r(x) and s(x)

(rs)(x) = 2\sqrt{x} * \sqrt{x}

(rs)(x) = 2(\sqrt{x})^2

(rs)(x) = 2x

Substitute 4 for x

(rs)(4) = 2 * 4

(rs)(4) = 8

$59.75 camera, 4% sales tax <br> please show in full detail
jek_recluse [69]

Answer:

The total cost would be: $62.14

Step-by-step explanation:

First convert the percent to a decimal, so since it is 4%, you move the decimal two places to the right, so it would be .04.

Next, multiply $59.75 x .04%.  This equals $2.39.

Then, take the product and add it to $59.75. So, $59.75 + $2.39.

This equals $62.14!

Two cars leave towns 360 kilometers apart at the same time and travel toward each other. One car’s rate is 10 kilometers per hou
Goryan [66]

9514 1404 393

Answer:

  85 km/h

Step-by-step explanation:

Let s represent the speed of the slower car. Then the travel time is ...

  time = distance/speed

  2 = 360/(s +(s+10))

  4s +20 = 360 . . . . . multiply by 2s+10

  4s = 340 . . . . . . . . . subtract 20

  s = 85 . . . . . . . . . . . divide by 4

__

The rate of the slower car is 85 km/h.

Pete's Convenience Store has a beginning inventory of 12 cans of soup at a cost of $.85 each. During the year, the store purchas
Zepler [3.9K]

A) The number of cans of soup in ending inventory is <u>19.</u>

B) The cost of the ending inventory under LIFO, FIFO, and the weighted average is as follows:

LIFO                                  $17.15

FIFO                                 $25.65

Weighted average          $21.47

<h3>What are the inventory methods?</h3>

The inventory methods include First-in, First-out (FIFO), Last-in, First-out (LIFO), Weighted Average, and Specific Identification.

FIFO assumes that the physical flow of goods during sales follows the chronological sequence of their acquisition.

LIFO assumes that the first goods acquired are the last to be sold.

The Weighted Average uses an average to determine the costs allocated to ending inventory and the cost of goods sold.

Specific Identification identifies the specific goods sold with their costs.

Description                 Units Unit Cost  Total

Beginning inventory     12     $0.85     $10.20

Purchases                      4     $0.95       $3.80

Purchases                      6     $1.05        $6.30

Purchases                      7     $1.35        $9.45

Purchases                     8     $1.50       $12.00

Total                            37                     $41.75

Sales                            18

Ending inventory        19 (37 - 18)

Average cost = $1.13 ($41.75/37)

<u>LIFO</u>:

Ending inventory = $17.15 ($10.20 + $3.80 + 3 x $1.05)

<u>FIFO</u>:

Ending inventory = $25.65 (4 x $1.05 + $9.45 + $12.00)

<u>Weighted Average</u>

Ending inventory = $21.47 (19 x $1.13)

A team of seven workers started a job, which can be done in 11 days. On the morning of the fourth day, several people left the t
Harman [31]

Hello!

To first solve this problem, let's look at how much the workers would've finished when they were still a group.

Since the job could've been originally done in 11 days with 7 people, and they only worked for 3 days (with 7 people), they originally finished 3/11 of the job.

Now, let's look at how much each person finishes of the job in one day.

Since 7 workers can finish the job in 11 days, this means that 1 worker can finish the job in 77 days, translating to that one worker does 1/77 of the job in one day.

Let's connect these ideas. There is 8/11 of the project remaining, and this was finished in 14 days. This means, every day, 4/77 of the project was finished. (8/11 divided by 14)

Since we know one worker does 1/77 of the job per day, and every day, 4/77 of the job was finished, 4 workers were on the team.

Therefore, 7-4, 3 workers left the team.

Hope this helped!
