Answer:

Solution : 126π/5

Step-by-step explanation:

Step 1 (Assign the 'values') : Using the cylinder method, given that x = 0 and x = 3, we will integrate along the x-axis from 0 to 3. The radius of each cylinder will be r = x, and the height should be the following,

h = y₁ - y₂ = x³ - 8

Step 2 (Substitute) : Remember that the volume of the graph will be in the following form,

\mathrm{V\:=\:2\pi \int _a^b\:rhdx}

If we substitute known values we should go in the following both. Remember that r = x, h = x³ - 8, b = 3, and a = 0 (our limits). Take a look at the attachment for those calculations. As you can see our solution is 126π/5.

Martine’s town is building a volleyball court based on a scale drawing that is 40cm to 80cm and uses the scale 1cm:22.5cm write
never [62]

Answer:

y=22.5x

Step-by-step explanation:

we have that

The scale drawing is

\frac{1}{22.5}\frac{cm}{cm}

we know that

Using proportion find out the actual dimensions of the volleyball court

Let

x -----> drawing court lengths in cm

y ----> court lengths in cm

For x=40 cm

\frac{1}{22.5}\frac{cm}{cm}=\frac{40}{y}\frac{cm}{cm}\\\\y=40*22.5\\\\y=900\ cm

For x=80 cm

\frac{1}{22.5}\frac{cm}{cm}=\frac{80}{y}\frac{cm}{cm}\\\\y=80*22.5\\\\y=1,800\ cm

Find the equation for the proportional relation ship between drawing court lengths x in centimeters and court lengths in y centimeters

 A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

For x=40 cm, y=900

substitute

k=y/x -----> k=900/40=22.5

The equation is

y=22.5x

What is the least common denominator of 1/2, 2/3 and 3/4
Vinil7 [7]

Answer:

6/12, 8/12, and 9/12.

Step-by-step explanation:

Let's find the least common denominator:

First, the least common multiple of 2, 3, and 4 is 12.

12 is divisible by 2, 3, and 4.

<u>Next, multiply the denominators with the numerators:</u>

Products: 6/12, 8/12, and 9/12
