Which equation represents the relation that is shown in the graph?

Cost of Buying Comic Books
On a coordinate plane, a graph titled Cost of Buying Comic Books has number of issues on the x-axis and total cost on the y-axis. A line goes through points (0, 0), (1, 3.5), (2, 7).

Answer:

Answer:

Step-by-step explanation:

1 box costs x amount

18 boxes cos 223.20

Cross multiply

223.20 * 1 = 18 x

Divide by 18

223.20 / 18 = 18x / 18

x = 12.40

Cost of 1 box is 12.40

Answer:

It should be 199.20 for 16 boxes

Step-by-step explanation:

I divided 273.90 by 22 which came out to 12.45

so then i multiplied 12.45 by 16 and it gave me 199.20

The difference between the two prime numbers 17 and 39 is 22.

Prime numbers are those who have only two factors: 1 and the number on its own.

For the number given:

22 17 25 41 39 4

The two primes numbers are 17 and 39.

The difference is 39 - 17 = 22.

Thus, the difference between the two prime numbers is 22.

I do not agree. To find how fast Spotify is downloading songs, divide the number of songs already downloaded by how long the playlist has been downloading.

Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operations.

For example, assume that you are downloading a playlist that has 100 songs. 80 songs have been downloaded in the past two hours. In order to determine the rate at which songs are downloaded, divide 80 by 2.

Speed = 80 / 2 = 40 songs per hour

The mass of the wire is found to be 40π√2 units.

To calculate the mass of the wire which runs along the curve r ( t ) with the density function δ=5.

The general formula is,

Mass = [tex]\int_a^b \delta\left|r^{\prime}(t)\right| d t[/tex]

To find, we must differentiate this same given curve r ( t ) with respect to t to estimate |r'(t)|.

The given integration limits in this case are a = 0, b = 2π.

Now, as per the question;

The equation of the curve is given as;

r(t) = (4cost)i + (4sint)j + 4tk

Now, differentiate this same given curve r ( t ) with respect to t.

[tex]\begin{aligned}\left|r^{\prime}(t)\right| &=\sqrt{(-4 \sin t)^2+(4 \cos t)^2+4^2} \\&=\sqrt{16 \sin ^2 t+16 \cos ^2 t+16} \\&=\sqrt{16\left(\sin t^2+\cos ^2 t\right)+16}\end{aligned}[/tex]

Further simplifying;

[tex]\begin{aligned}&=\sqrt{16(1)+16} \\&=\sqrt{16+16} \\&=\sqrt{32} \\\left|r^{\prime}(t)\right| &=4 \sqrt{2}\end{aligned}[/tex]

Now, use integration to find the mass of the wire;

       [tex]\begin{aligned}&=\int_a^b \delta\left|r^{\prime}(t)\right| d t \\&=\int_0^{2 \pi} 54 \sqrt{2} d t \\&=20 \sqrt{2} \int_0^{2 \pi} d t \\&=20 \sqrt{2}[t]_0^{2 \pi} \\&=20 \sqrt{2}[2 \pi-0] \\&=40 \pi \sqrt{2}\end{aligned}[/tex]

Therefore, the mass of the wire is estimated as 40π√2 units.

The value of ∠EFD is 107 ° as this angle is part of a linear pair .

When two lines cross at one point, a linear pair of angles is created. If the angles follow the intersection of the two lines in a straight line, they are said to be linear. A linear pair's total angles are always equal to 180°.

Given the two angles are ∠EFD and ∠DFG .

Now as they are on a straight line they form a linear pair .

As a part of a linear pair their sum add up to  180°.

Now substituting the given values :

11x - 3 + 6x + 13 = 180

or, 17 x + 10 =180

or, 17 x = 170

or, x = 10

Therefore the value of the ∠EFD is given as 11x - 3 = 110 - 3 = 107° .

Answer:

The slope is [tex]-\frac{3}{4}[/tex]

Step-by-step explanation:

To find the slope, you take 2 points and use rise/run. I used (0,1) and (4,-2) because they look like they are being touched by the line. So by looking at the graph, I have to look at how I can get from (0,1) to (4,-2). So from (0,1), I go down 3 units which makes my number -3, over the run which is 4 units to the right, which makes it positive. so I went down 3 and then went right 4, making this    [tex]-\frac{3}{4}[/tex]. You could also use point-slope which means [tex]\frac{y2-y1}{x2-x1}[/tex] or [tex]\frac{-2-1}{4-0}[/tex] which equals the same thing

48 = 2⁴•3

and GCD(28, 42) = 2² = 4.

There are 4 dollar bills are in a 0.28 inch stack.

Given that, the size of a dollar bill is width= 6.6 cm, length=15.6 cm and height= 0.109 mm= 0.109/10 =0.0109 cm.

The volume of the cuboid is the measure of the space occupied within a cuboid. The cuboid is a three-dimensional shape that has length, breadth, and height. If we have a rectangular sheet and we go on stacking such sheets, we will end up getting a shape that has some length, breadth, and height. The formula to find the volume of the cuboid = Length × Width × Height.

Now, the volume of a dollar bill=15.6 × 6.6 × 0.0109

=1.122264 cm³

Conversion of cm³ to cubic inches.

That is, 1.122264×0.0610237=0.06848≈0.07

The values of r and s is -1 and -4 respectively.

Given that:-

coordinates of j are (-8,-5)

coordinates of l are (6,-11)

coordinates of k are (r-4,2s)

Also, k is the mid-point of jl.

We have to find the values of r and s.

We know that, for  (x,y) and (z,w), the mid-point is ((x+z)/2, (y+w)/2).

Here,

(x,y) = (-8.-5)

(z,w) = (6,-11)

(r-4,2s) = ((x+z)/2,(y+w)/2)

Hence,

(r-4,2s) = ((-8+6)/2,(-5-11)/2)

(r-4,2s) = (-1,-8)

Comparing the coordinates, we get:-

r - 4 = -1

r = -1+4 =3

2s = -8
