on the grid draw the graph of y = 3x + 2 for values of x + 2 for values of x from -2 to 2

The height of the triangle is 0.00625.The correct option is D

A density graph must have an area under it equal to 1. The range of speeds in this problem, 320-0 = 320, is the base of the density graph, which is shaped like a triangle. By multiplying the base by half of the triangle's height, we can determine the density graph's area.

Let h represent the triangle's height. The triangle's area is then:

1 = (1/2)320h

calculating h:

h = 1 / (320/2) = 0.00625

Therefore, option D is appropriate because the triangle's height is 0.00625.

Answer:

the distance between them is decreasing at a rate of 2 mph.

Step-by-step explanation:

List all given rates and the unknown rate.

Write the formula that relates the variables in the problem: x, y, and s.

There’s a right triangle in the diagram, so you use the Pythagorean Theorem:

For this problem, x and y are the legs of the right triangle, and s is the hypotenuse, so

Differentiate with respect to t.

Use the Pythagorean Theorem again to solve for s.

x = 0.4

y = 0.3

You can reject the negative answer because s obviously has a positive length. So s = 0.5.

Now you’ve got everything you need to substitute into the differentiation result and solve for ds/dt.

This negative answer means that the distance, s, is decreasing. Thus, when car A is 3 blocks north of the intersection and car B is 4 blocks east of the intersection, the distance between them is decreasing at a rate of 2 mph.

Answer:

$1.75

Step-by-step explanation:

Set up a system of equations where x is the cost of a corndog and y is the cost of a coke:

3x + y = 7.1

2x + 2y = 7.2

Solve by elimination by multiplying the top equation by -2

-6x - 2y = -14.2

2x + 2y = 7.2

Add them together:

-4x = -7

x = 1.75

So, the cost of one corndog is $1.75

Step-by-step explanation:

The statement supported the graph is

The axis of symmetry is x = 3

The coordinates of the y-intercept are (0,7)

A line that divides an object into two equal halves and produces a mirror-like reflection of each side of the object is known as an axis of symmetry.

1. The axis of symmetry is x = 3

The axis of symmetry is the central axis of the graph, which signifies the middle point of the graph. It is evident that this graph is centered on x = 3.

2. The coordinates of the y-intercept are (0,7)

The y intercept is the point where the graph meets the y-axis, that is, the value of y on the graph when x=0.

From the graph, the coordinates of the y-intercept is (0, 7)

3. The X-intercept is located at (-3,0)

The x intercept is the point where the graph meets the x-axis, that is, the value of x on the graph when y=0.

From the graph the curve x axis at x= 1.5 and x= 4.5

So, the x-intercept is truly located at (1.5, 0) and (4.5,0)

Answer:

1. D

2. y = 15.50x + 450

Step-by-step explanation:

1. Since it is a function, the missing pair can't repeat input values with different output, therefore only option D is unique so is the correct choice.

2. x  > (y - 450)/ 15.50

i) Rita gets paid $450 per week.

ii) She gets $15.50 for every new membership she sells.

iii) let y represent the total pay per week.

iv) let x represent the number of new memberships sold.

v) the equation representing total pay is y = 15.50x + 450.

vii) therefore the equation that represents a higher rate of membership sold is given by  x  > (y - 450)/ 15.50

Answer:

the total earnings is $58

Step-by-step explanation:

The computation of earnings is shown below:

= Time spent in filling paperwork + time spent in sending emails + time spent in making appointments

= (1 5 ÷ 12 × $10.50)  + (1 3 ÷ 4 × $10.50)  + (2 1 ÷ 3 × $10.50)

= 14.875 + 18.375 + 24.50

= $57.75

Hence, the total earnings is $58

Answer:

Here, for example, is square inch pricing, using a multiplier of 2.5 (ie, $2.50 per square inch):

4×4 inches = 16 square inches x 2.5 = $40

8×8 inches = 64 square inches x 2.5 = $160

16×16 inches = 256 square inches x 2.5 = $640

24×24 inches = 576 square inches x 2.5 = $1,440

32×32 inches = 1,024 square inches x 2.5 = $2,560

I don’t know about you, but $40 seems awfully small price for a painting by someone who commands $2,560 for a 32×32 canvas.

Here are the same canvas sizes using linear inch pricing, using a multiplier of 20 (ie, $20.00 per linear inch) — as you can see, the difference in price feels a lot less out-of whack:

4+4 inches = 8 linear inches x 20 = $160

8+8 inches = 16 linear inches x 20 = $320

16+16 inches = 32 linear inches x 20 = $640

24+24 inches = 48 linear inches x 20 = $960

32+32 inches = 64 linear inches x 20 = $1,280

Neither of these pricing methods is “right” or “wrong,” but once you determine your method and your multiplier, charging by size can be a very helpful way to eliminate the guesswork, and feel confident about your pricing.

Different Pricing for Different Media?

One possible modifier to your size-based pricing structure is the media you paint with. If you only paint watercolors, or only paint oils, there’s no problem, but if you paint both on canvas and on paper, as I do, it gets a little tricky.

For whatever reason, paintings on paper tend to sell for less than paintings on canvas — even though they require framing, which is an added expense. In my case, if I were to pay to have a piece framed, my costs become much higher for a work on paper than for a canvas painting! What’s an artist to do?

(And remember that pricing your prints is an entirely different topic.)

Answer:

55

Step-by-step explanation:

75+50=125

180-125=55

Answer:

We know that per week, she works 18 hours.

For each of these hours, she earns $13.

Then in one week, she earns a total of:

18*$13 = $234

This is her gross pay (the pay before the taxes apply)

Now we know that her employer takes:

15% for federal income tax withholding.

6.2% for Social Security

1.45% for Medicare.

If we add all of these, we get:

15% + 6.2% + 1.45% = 22.65%

This means that 22.65% of $234, is taken by her employer to pay taxes and such.

Then the amount left is:

M = $234 - ( 22.65%/100%)*$234 = $234 - 0.2265*$234 = $180.999

And we can round the last digit to $181 (because we can not have a 0.009 of a cent)

This means that her weekly net pay is $181

And she works for 12 weeks, this means that in total, she will earn:

12*$181 = $2,172

Answer:

The answer should be 14/15.
