Answer:

$12.09

Step-by-step explanation:

formula; Y= kx

where;    y = $24.18

               x = 2 books

               k = constant of proportionality

Step 1. Do the equation based on the data given

Y = kx

$24.18 = k2

Step 2. Compute the mathematical equation. Divide both sides by 2 to eliminate coefficient in the variable.

<u>24.18 =k2</u>

       2

k = $ 12.09 is the constant of proportionality cost in dlooars per book

The formula for the volume of a sphere is v= 4/3 m^3 what is the formula solved for r ?
Softa [21]

Answer:

            3V

r = ∛ ( ---------- )

            4π

Step-by-step explanation:

Please, enclose the fraction 4/3 inside parentheses, to eliminate any possibility of misreading this fraction.  Also note that this formula MUST include "pi," symbolized by π.

V = (4/3) π r³  This formula does NOT include "m," which is a unit of measurement, not a variable.

Our task is to solve this formula for the radius, r.

Divide both sides by (4/3) π, to isolate r³.  This results in:

      v               (4/3) π r³

-------------   =  -----------------

  (4/3) π             (4/3) π

                     

                       V              3V

Then r³ = --------------  =  --------

                   (4/3) π           4π

and r is found by taking the cube root of the above result:

            3V

r = ∛ ( ---------- )

            4π

If x &gt; 0 and y &gt; 0, where is the<br> point (x, y) located?
Scrat [10]
  • Given, x > 0, y > 0.
  • So, the values of x and y are less than 0, that means, they are negative integers.
  • If we divide a Cartesian plane with the x-axis and y-axis, we get four quadrants.
  • 1st Quadrant : (+,+)
  • 2nd Quadrant : (-,+)
  • 3rd Quadrant : (-,-)
  • 4th Quadrant : (+,-)
  • Since the values of x and y are both negative, so (x, y) is located in the <em><u>3rd Quadrant</u></em>.

Hope you could get an idea from here.
