Find the volume (in units3) generated when the region between the curves is rotated around the given axis. x = y2 and y = x rota
densk [106]

The volume (in units3) is generated when the region between the curves is rotated around the given axis.is  mathematically given as

v=\frac{5 \pi}{6}

<h3>What is the volume (in units3) generated when the region between the curves is rotated around the given axis. ?</h3>

The region is bound by

x=y^2

y=x

y=3

Where

y=√x

Generally, the equation for Washer Method is  mathematically given as

v=\int ^1_0 \pi ((outer curve)^2-(inner Curve)^2) dx

Therefore

v=\int_{0}^{1} \pi(-7 x)+\pi x^{2}+6 \pi \sqrt{x} d x

v=$\frac{5 \pi}{6}$

In conclusion, The result can be shown in multiple forms

Exact Form:

$\frac{5 \pi}{6}$

Decimal Form:

2.61799387

Follow the directions to solve the system of equations by elimination. 8x + 7y = 39 4x – 14y = –68 Multiply the first equation t
g100num [7]

Answer:

x=0.5 and y=5

Step-by-step explanation:

8x+7y=39...eqn(1)×-14

4x-14y=-68...eqn(2)×7

we now have,

-112x-98y=-546

-(28x-98y=-476)

-140x÷-140 =-70÷-140

x=0.5

to solve for y, we substitute (x=0.5) into eqn (1) or eqn 2 which ever you want...

so I'm using eqn 1.

8x+7y=39

8(0.5)+7y=39

7y=39-4

7y÷7=35÷7

y=5

therefore, x=0.5, y=5

proof: substitute both x and y values to get you the same answer as the original solutions in both equations.

we have,

8(0.5)+7(5)=39

4(0.5)-14(5)=-68
