Determine the constant of proportionality, k, and interpret it in the context of each problem. 2) The graph shows the relationship between the number of euros Jason received and the number of dollars Jason exchanged during his trip to Spain. *
Answers
The constant of proportionality Or the value of Euros is 3/2 times of the value of a dollar.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
To obtain the constant of proportionality we'll need to determine at least two coordinate points from the graph they are, (1, 3/2) and (2, 3).
Let, no. of dollars be 'x' and no. of euros be 'y'.
So, y = kx.
3/2 = k.
Another way is (3 - 3/2)/(2 - 1).
= (3/2)/1
= 3/2.

Answers
Answer:
x = -8 and y= 8
(-8,8) is the answer
Answer:
(2,4) (-4,16)
Step-by-step explanation:
Subtract 2 x from both sides of the equation.
y = 8 − 2 x
Substitute 8 − 2 x for y into x ^2 − y = 0 then solve for x .
x = 2 , − 4
Substitute 2 for x into x 2 − y = 0 then solve for y .
y=4
Substitute − 4 for x into x 2 − y = 0 then solve for y .
y=16
Equation form
x = 2 , y = 4
x = − 4 , y = 16

Point B is the center of the circle shown, and the length of arc AC is 8π. What is the area of the circle?
Answers
Answer:
[tex]A=324\pi \text{ units}^2\approx1017.88\text{ units}^2[/tex]
Step-by-step explanation:
The formula for arc length is:
[tex]\stackrel{\frown}{A}=2\pi r(\frac{\theta}{360}})[/tex]
Where Θ is measured in degrees.
We know that the arc length is 8π when the degree is 80. So, substitute 8π for A and 80 for Θ:
[tex]8\pi=2\pi r(\frac{80}{360})[/tex]
Divide both sides by 2π:
[tex]4=r\frac{80}{360}[/tex]
Simplify the fraction:
[tex]4=\frac{2}{9}r[/tex]
Multiply both sides by 9/2:
[tex]r=18[/tex]
So, the radius is 18.
Now, we can find the area of the circle. The formula for the area of a circle is:
[tex]A=\pi r^2[/tex]
Substitute 18 into r:
[tex]A=\pi (18)^2[/tex]
Simplify:
[tex]A=324\pi \text{ units}^2\approx1017.88\text{ units}^2[/tex]
And we're done!

What steps would you take in order to solve the equation 38 = 6x – 16? subtract 16 and then divide by 6 divide by 6 and add 16 add 16 and divide by 6 multiply by 6 and add 16
Answers
Answer:
x = 9
Step-by-step explanation:
38 = 6x - 16
Situate the x to one side -6x = -16-38
-6x = -54
-x = -9
x = 9
Then, divide birth sides of the equation by 6 to get 9=x, or x=9.
