Evaluate the double integral i=∫∫dxyda where d is the triangular region with vertices (0,0),(4,0),(0,4).

mario62 [17]

$I=\displaystyle\iint_D\mathrm dA=\int_{x=0}^{x=4}\int_{y=0}^{y=4-x}\mathrm dy\,\mathrm dx$
$I=\displaystyle\int_{x=0}^{x=4}(4-x)\,\mathrm dx$
$I=8$

To verify this, we can simply find the area of the triangle using the well-known formula $\dfrac12bh$ , where $b$ and $h$ are the base and height, respectively of the triangular region $D$ . We have $b=h=4$ , so the area is $\dfrac{4^2}2=8$ , as expected.

The mass of a small virus is 10^-20 kg. The mass of an average human cell is 10^-12 kg. Which of the two has lesser mass? how ma

fredd [130]

For this case we have:

$10 ^ {- 20}$ , we must run the decimal point 20 spaces to the left.

$0.00000000000000000010 \ kg$

$10 ^ {- 12}$ , we must run the decimal point 12 spaces to the left.

$0.000000000010 \ kg$

Thus, it is observed that the mass of a small virus is smaller!

We subtract and obtain:

$10 ^ {-11}$

ANswer:

The mass of a small virus is less!

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

- 4x + 3y = 12 ( add 4x to both sides )

3y = 4x + 12 ( divide the terms by 3 )

y = $\frac{4}{3}$ x + 4 ← in slope- intercept form

with slope m = $\frac{4}{3}$ and y- intercept c = 4

---------------------------------------------------

Given

- 5x + 3y = - 9 ( add 5x to both sides )

3y = 5x - 9 ( divide the terms by 3 )

y = $\frac{5}{3}$ x - 3 ← in slope- intercept form

with slope m = $\frac{5}{3}$ and y- intercept c = - 3
