Solution:

1. When we talk about a line , it means it has infinite length and there are infinite number of points on it.

And there is not a single way to name a line, there are infinite number of ways to name a line by placing any two points on the line .We don't need to put bar(-) while naming a line by considering two points on the line.

So, Option B: The line has infinitely many points. is true option.

2. PM -= A line segment

So, it has definite length and we need to put bar (-) over it.It can be written either as PM or MP having bar over it.

Option B: MP−→− is true option.

Solve equation 5(n-4) = -60

Katena32 [7]

Answer:

n = -8

Step-by-step explanation:

The variable has 4 subtracted and that quantity is multiplied by 5. You can find the value of the variable by reversing these operations, in reverse order. That means you first divide both sides of the equation by 5:

5(n-4)/5 = -60/5

n -4 = -12 . . . . . . simplify

Then you undo the subtraction of 4. You accomplish that by adding 4 to both sides of the equation.

n -4 +4 = -12 +4

n = -8 . . . . . . . . . simplify

_____

This equation can also be solved by first eliminating parentheses. Then you have

5n -20 = -60

Now, the variable is multiplied by 5, then 20 is subtracted from the sum. Reversing these operations in reverse order, we first add 20 to both sides of the equation:

5n -20 +20 = -60 +20

5n = -40 . . . . . . . . . . . . . simplify

Then we undo the multiplication by dividing both sides of the equation by 5:

n = -8

_____

The rule to remember is "whatever you do to one side of the equation must also be done to the other side". This is what keeps the equal sign valid.

The line integral of xydx×x^2y^3dy where c is the triangle with points (0,0) (1,0) (1,2) using green's theorem

lyudmila [28]

If $\mathcal C$ is the boundary of the triangle $D$ , then by Green's theorem

$\displaystyle\int_{\mathcal C}xy\,\mathrm dx+x^2y^3\,\mathrm dy=\iint_D\left(\frac{\partial(x^2y^3)}{\partial x}-\frac{\partial(xy)}{\partial y}\right)\,\mathrm dA$
$=\displaystyle\int_{x=0}^{x=1}\int_{y=0}^{y=2x}(2xy^3-x)\,\mathrm dy\,\mathrm dx$
$=\displaystyle\int_{x=0}^{x=1}x\int_{y=0}^{y=2x}(2y^3-1)\,\mathrm dy\,\mathrm dx$
$=\displaystyle\int_{x=0}^{x=1}x(8x^4-2x)\,\mathrm dx=\frac23$
