Use a triple integral to find the volume of the given solid. The tetrahedron enclosed by the coordinate planes and the plane 2x

scZoUnD [109]

Answer:

$\mathbf{V = \dfrac{2}{3}}$

Step-by-step explanation:

Consider the tetrahedron enclosed by the coordinate planes and the plane 2x + y + z = 2

Let A be the region obtained by projecting the volume(V) onto the xy-plane.

Similarly, the plane 2x + y + z = 2 intersects with the xy-plane in y = 2 - 2x.

Using the vertical strips, the region A is to the xy-plane can be expressed as:

$A = \{(x,y) | 0 \le x \le 1, 0 \le y \le 2 - 2x\}$

Thus, the volume of the solid can be calculated as follows;

$V = \int^1_0 \int ^{2-2x}_{0} \int ^{2-2x-y}_{0} \ dz \ dy \ dx$

$V = \int^1_0 \int ^{2-2x}_{0} (2-2x-y) \ dy \ dx$

$V = \int^1_0 \bigg [2\times y -2x\times y - \dfrac{y^2}{2} \bigg]^{2-2x}_{0} \ dx \$

$V = \int^1_0 \bigg [2\times (2-2x) -2x\times (2-2x) - \dfrac{(2-2x)^2}{2} \bigg]\ dx$

$V = \int^1_0 \bigg [2x^2-4x+2 \bigg]\ dx$

$V = \bigg [2\dfrac{x^3}{3}-\dfrac{4x^2}{2}+2 x\bigg]^1_0$

$V = \bigg [2\dfrac{(1)^3}{3}-\dfrac{4(1)^2}{2}+2 (1)-0\bigg]$

$V = \dfrac{2}{3}- 2 + 2$

$\mathbf{V = \dfrac{2}{3}}$

Please help!! Which is correct

atroni [7]

Answer:

3rd

Step-by-step explanation:

Just look at the second equation in each system (no need to look at the others). The third is the only one that makes sense. The total value means the number of coins multiplied by value of each. The value in dollars is $9.35

If the value in the equation is in dollars, the variables must be multiplied by values in dollars. You can't multiply with 5 cents per nickle to equal 935 dollars. Makes no sense.
