Range is from the lowest y value on the graph to the highest y value. There are different ways of writing range, and the way you write it depends on your teacher.

I will show you the ways I know.
[-5,6]

-5 is less than or equal to 0 is less than or equal to 6

I hope this helps!

A sphere of radius 2x m has an area of ​​152.4 m2 and a volume of 360.9 m3. How much will the area and volume of another sphere
VladimirAG [237]

Answer:

V = 1218.0375m^{3}

A = 342.9m^{2}

Step-by-step explanation:

Area:

A = π r^{2}

152.4 = π (2x)^{2}       *Square 2x*

152.4 = π 4x^{2}          *Divide by π*

48.510 = 4x^{2}           *Divide by 4*

12.128 = x^{2}             *Square root*

\sqrt{12.128} = x           *Solve*

x ≈ 3.482

Now take the same equation but replace 2x with 3x

A = π r^{2}\\

Now replace x with 3.482 and solve for area.

A = 342.9m^{2\\}

Volume:

V = \frac{4}{3} π r^{3}               *Insert variables*

360.9 = \frac{4}{3} π (2x)^{3}     *Cube 2x*

360.9 = \frac{4}{3} π (8x^{3})     *Multiply \frac{3}{4} on both sides*

270.675 = π (8x^{3})    *Divide by π*

86.159 = 8x^{3}           *Divide by 8*

10.770 = x^{3}             *Cube root*

\sqrt[3]{10.770} = x            *Solve*

x ≈ 2.208

Now take the same equation but replace 2x with 3x

V = \frac{4}{3} π (3x)^{3}    

Now replace x with 2.208 and solve for volume.

V = 1218.0375m^{3}

sleet_krkn [62]

Answer:

  $2

Step-by-step explanation:

The price of each calculator is found by dividing the box price by the number of calculators in the box.

  $30/5 -$32/8 = $6 - $4 = $2

In boxes of 8, each calculator costs $2 less.
