An electrician charges a flat fee for each job, plus an hourly rate for each hour he takes to complete the job. The total cost of the job can be modeled by the equations y = 50 + 65x. What does the independent variable represent in this situation?

Answers

Answer 1

Answer: The independent variable = x which represent the the number of hours taken to complete the job.

Step-by-step explanation:

Independent variable is the variable on which dependent variable is dependent.

In the given function: y = 50 + 65x, x = Number of hours, y = Total cost of the job.

Here, total  cost of the job depends on the number of hours.

So the independent variable = x which represent the the number of hours taken to complete the job.

plz help me find answer. what are the coordinates of slope when y= x/1–x² when dy/dx=1​

Answers

Step-by-step explanation:

dy/dx

= d/dx [x / (1 - x²)]

= [(1 - x²)(1) - (x)(-2x)] / (1 - x²)²

= (1 + x²) / (1 - x²)².

When dy/dx = 1, (1 + x²) / (1 - x²)² = 1.

=> 1 + x² = 1 - x²

=> 2x² = 0, x = 0.

Also when x = 0, y = (0) / [1 - (0)²] = 0.

Hence the coodinates is (0, 0).

Choose the description that matches the inequality p > -3.
A line traveling to the right with a closed dot on p = -3.
A line traveling to the left with an open dot on p = -3.
A line traveling to the left with a closed dot on p = -3.
A line traveling to the right with an open dot on p = -3.

Answers

Answer:

The correct option is:  A line traveling to the right with an open dot on p = -3.

Option D is correct option.

Step-by-step explanation:

Choose the description that matches the inequality [tex]p > -3[/tex].

The inequality states that, the value of p is greater than -3

For drawing the number line for the inequality, we know that if p > -3, there will be open circle on -3 because -3 is not included and the greater values are on the right side of number line, so line will be travelling to right side.

The number line is attached in figure.

So, The correct option is:  A line traveling to the right with an open dot on p = -3.

Option D is correct option.

An apple tree measures 20 1/2 feet tal,over the next five years,it grew to the height of 28 feet. What was the average yearly growth of the apple tree

Answers

Answer:

6.4%

Step-by-step explanation:

We solve this question in using the population growth rate formula

P(t) = Po(1 + r)^t

P(t) = Population after t years = 28 ft

Po = Initial Population = 20 1/2 feet or 20.5 feet

r = Growth rate = ?

t = Time in years = 5

Hence:

28 = 20.5 (1 + r)⁵

Divide both side by 20.5

28/20.5 = 20.5 (1 + r)⁵/20.5

1.3658536585 = (1 + r)⁵

5th root both sides.

5√(1.3658536585) = 5√(1 + r)⁵

1.0643411027 = 1 + r

r = 1.0643411027 - 1

r = 0.0643411027

Converting to percentage

r = 0.0643411027 × 100

r = 6.43411027%

Approximately = 6.4%

The yearly growth rate of the apple tree = 6.4%

Then after you graph what is the ordered pair (x,y)

The Smiths spend 6% of their budget on entertainment. Their total budget this year is $2,000 more than last year, and this year they plan to spend $2,760 on entertainment. What was their total budget last year? Their total budget last year was?

Answers

Answer: Their total budget last year was $44,000.

Step-by-step explanation:

Given: Smiths spend 6% of their budget on entertainment.

Total budget this year = $ 2000 more than last year.

Let x = Budget for this year.

Money on entertainment = 0.06x = 2760

[tex]\Rightarrow\ x=\dfrac{2760}{0.06}= \$46,000[/tex]

⇒ Budget for this year = $ 46,000

Budget for last year = $ 46,000 - $2,000 = $44,000

Hence, their total budget last year was $44,000.

Answers

Answer:

Approximately 0.6009

The value of tan 31 is 0.6008606.

What is Trigonometry?

The branch of mathematics concerned with specific functions of angles and their application to calculations.

As, the angle 31° lies between and 90° (First quad).

So, tangent function is positive in the first quadrant.

Tan 31 degrees= tan (0.54105 . . .) in radians.

As, using degree to radian conversion,

θ(radians) = θ in degrees × (π/180°)

31 degrees = 31° × (π/180°) rad

= 0.5410

So, tan 31°

= tan(0.5410)

= 0.6008606.

Hence, tan 31= 0.6008606.
