Solve the math problem

Mathematics
1 answer:
Kisachek [45]3 years ago
3 0

Answer:

See below & pic.

Step-by-step explanation:

Now I understand the problem.

I corrected the answers I had given you, and wrote them in the blanks, and I filled in the rest a drew the graph.

See the picture below.

I think the question is not the cost and the earnings per hour. Rathe it means the cost and earnings as a function of hours.

I wrote those equations. Then I filled in the tables.

The breakeven point, when cost and earnings are equal, is at 6 hours, when both cost and earnings are $54. That is where the two lines intersect in the graph.

Simplify<br><br> a+a+a=<br> 4b-b<br> 3x2+x2
Reika [66]
<h2>Good morning,</h2>

<em><u>__________________</u></em>

<em><u>Answer</u></em>:

a+a+a = 3a.

4b-b = 3b.

3x²+x² = 4x².

<u><em>explanation</em></u>

a+a+a = 3a.

4b-b = b(4 - 1) = b × 3 = 3b.

3x²+x² = x²(3 + 1) = x² × 4 = 4x².

A town has a population of 6000 people in the year 2009 and is growing at a rate of 3% a year. Let t denote the time in years af
dusya [7]

Answer:

  • f(t) = 6000*1.03^t
  • k = 0.0295588

Step-by-step explanation:

The formula for exponential growth can be written a couple of different ways. One I prefer uses the problem numbers directly:

  population = (initial population) × (growth factor)^t

Here, the initial population is 6000, and the growth factor is 1+3% = 1.03. Then the function can be written as ...

  f(t) = 6000·1.03^t

__

Another way to write the function is using the form ...

  f(t) = (initial population) × e^(kt)

where k is the natural logarithm of the growth factor. In this form, we have ...

  k = ln(1.03)

  k ≈ 0.0295588

so the function would be written ...

  f(t) = 6000·e^(0.0295588t)

Plisss help me in thiss
ahrayia [7]

Answer:

x=80

Step-by-step explanation:

The angle of a line is 180*.

The equation would be (x+20)+x=180

Subtract 20 from both sides: 2x=160

Divide by 2: x=80

That's your answer!

I hope this helps!
