Evaluate the triple integral.

Irina-Kira [14]

The definition of the set E gives you a natural choice for the limits in the integral:

$\displaystyle \iiint_E y \, dV = \int_0^6 \int_0^x \int_{x-y}^{x+y} y \, dz \, dy \, dx$

Computing the integral, we get

$\displaystyle \iiint_E y \, dV = \int_0^6 \int_0^x y ((x+y)-(x-y)) \, dy \, dx = 2 \int_0^6 \int_0^x y^2 \, dy \, dx$

$\displaystyle \iiint_E y \, dV = 2 \int_0^6 \frac13 (x^3 - 0^3) \, dx = \frac23 \int_0^6 x^3 \, dx$

$\displaystyle \iiint_E y \, dV = \frac23 \cdot \frac14 (6^4 - 0^4) = \boxed{216}$

What is the algebraic expression for the difference between seven times a number and three times that number?

anastassius [24]

Given

An algebraic expression is the difference between seven times a number and three times that number.

To find:

The algebraic expression.

Solution:

Let x be the unknown number.

Multiplication is used for times and subtraction is used for difference.

7 times of a number = 7x

3 times of that number = 3x

The difference between seven times a number and three times that number is

$Difference = 7x-3x$

$Difference =4x$

Therefore, the algebraic expression for the given statement is 7x-3x and its simplified form is 4x.
