Answer:

D = {–3, –1, 1, 2}; R = {–3, 1, 2, 4}

Step-by-step explanation:

  • We need to understand what is the domain of a function?

<em>The domain is the set of all possible x-values which will make the function "work"</em>

  • We need to understand what is the range of a function?

the range of the function is the set of all values that f(x) = y takes.

In your question,

  • all possible x-values : {–3, –1, 1, 2}
  • all possible y-values : {–3, 1, 2, 4}  

So, the domain and range of the following relation is C

D = {–3, –1, 1, 2}; R = {–3, 1, 2, 4}

Snezhnost [94]

Answer:

Small: 178

Large: 84

Step-by-step explanation:

L + S = 262

S = 262 - L

3L + S = 430

3L + 262 - L = 430

2L = 168

L = 84

S = 262 - 84

S = 178

Solve the problem using 6.2%, up to $128,400 for Social Security tax and using 1.45%, no wage limit, for Medicare tax.
maksim [4K]

Based on the social security tax rate and the Medicare tax, the monthly Social security is $109.12 and the Medicare tax is $25.52.

<h3>What is monthly social security act?</h3>

Graham, C. has not reached the $128,400 threshold for social security so the Social Security tax withholding for the month will be:

= Monthly salary x Social security rate

= 1,760 x 6.2%

= $109.12

The Medicare has no limit and so will be:

= 1,760 x 1.45%

= $25.52

The ratio of the profit, material cost and production labour of an article is 5:7:13.
IRINA_888 [86]

Answer:

The cost of producing the article is -3500 (Negative cost)

Step-by-step explanation:

The given parameters are

The ratio of the profit to material cost to production labor = 5:7:13

The amount of the material cost = 840 + Labor cost

Let the total cost = X

Therefore, we have;

The fraction of the total cost that is material cost = 7/(5 + 7 + 13) = 7/25

Therefore, the material cost = 7/25 × X

The fraction of the total cost that is labor cost = 13/(5 + 7 + 13) = 13/25

Therefore, the labor cost = 13/25 × X

However, the amount of the material cost = 840 + Labor cost, which gives;

7/25 × X = 13/25 × X + 840

7/25 × X - 13/25 × X = 840

-6/25 × X= 840

X = 840/(-6/25) = 840×(-25/6) = -3500

The cost of producing the article = -3500.

A bus traveled 336 miles in 7 hours. It traveled the same number miles each hour. If the bus continues at the same numder of mil
MrRissso [65]

Answer:

The bus will travel 720 miles in 15 hours.

Step-by-step explanation:

As you know that the bus traveled 336 miles in 7 hours and it traveled the same number miles each hour, you can divide the amount of miles it traveled by the number of hours to determine the amount of miles per hour:

336/7=48

Now, you can multiply the number of miles the bus traveled each hour for 15 hours:

48*15=720

According to this, the answer is that the bus will travel 720 miles in 15 hours.
