If PQ RS , which of the following must be true?

Anton [14]

Answer: B. $\overline{PQ}\ and\ \overline{RS}$ have the same length.

Step-by-step explanation:

We have given that $\overline{PQ}\cong\overline{RS}$ , where $\overline{PQ}\ and\ \overline{RS}$ are two line segments.

We know that if two line segments are congruent or equal then their lengths are equal.

Therefore, if $\overline{PQ}\cong\overline{RS}$ then it shows that $\overline{PQ}\ and\ \overline{RS}$ have the same length.

Hence, B is the right answer.

Algebra I

Coordinates (x, y)
Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (6, 2)

Point (9, 8)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{8-2}{9-6}$
[Fraction] Subtract: $\displaystyle m=\frac{6}{3}$
[Fraction] Divide: $\displaystyle m=2$

Use Green's Theorem to evaluate the following line integral. Assume the curve is oriented counterclockwise.

anzhelika [568]

By Green's theorem, the circulation of $\vec F(x,y)=\langle2xy^2,4x^3+y\rangle$ around $C$ is equal to

$\displaystyle\iint_D\frac{\partial(4x^3+y)}{\partial x}-\frac{\partial(2xy^2)}{\partial y}\,\mathrm dx\,\mathrm dy$

where $D$ is the region with $C$ as its boundary. The integral is equivalent to

$\displaystyle\int_0^\pi\int_0^{\sin x}(12x^2-4xy)\,\mathrm dy\,\mathrm dx=\boxed{\frac{23\pi^2}2-48}$
