Use green’s theorem to evaluate

Georgia [21]

By Green's theorem (all the conditions are met), we have

$\displaystyle \int_C \sqrt y \, dx + \sqrt x \, dy = \iint_D \frac{\partial(\sqrt x)}{\partial x} - \frac{\partial(\sqrt y)}{\partial y} \, dx \, dy$

where D is the interior of the path C, or the set

$D = \left\{ (x, y) : 0 \le y \le \dfrac{x^2}2 \text{ and } 0 \le x \le 2 \right\}$

So, the line integral reduces to the double integral,

$\displaystyle \frac12 \int_0^2 \int_0^{\frac{x^2}2} x^{-\frac12} - y^{-\frac12} \, dy \, dx$

$\displaystyle = \frac12 \int_0^2 x^{-\frac12}\left(\frac{x^2}2\right) - 2\left(\frac{x^2}2\right)^{\frac12} \, dx$

$\displaystyle = \frac12 \int_0^2 \frac12 x^{\frac32} - \sqrt 2 \, x \, dx$

$\displaystyle = \frac14 \int_0^2 x^{\frac32} - 2\sqrt 2 \, x \, dx$

$\displaystyle = \frac14 \left(\frac25\cdot2^{\frac52} - \sqrt2\cdot2^2\right) = \boxed{-\frac{3\sqrt2}5}$

It took a 3D priner 10528 minutes to print 87 percent of a 3D print job. At this rate of speed how much time will take for the p

11Alexandr11 [23.1K]

The time it would take for the print to reach 100 percent completion is 12,101 minutes 9 seconds.

<h3>What is time it would take to reach 100%?</h3>

The mathematical operations that would be used to determine the required value are division and multiplication. Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷. Multiplication is the process of determining the product of two or more numbers. The sign used to denote multiplication is ÷.

Other mathematical operations that are used to solve problems include addition and subtraction.

Time it would take to reach 100% completion = (minutes it takes to print 87% of the words x 100%) / 87%

Time it would take to reach 100% completion = (10,528 x 1) / 0.87 =

10.528 / 0.87

= 12,101. 15

= 12,101+ (0.15 x 60)

= 12,101 minutes 9 seconds

Classify the equation as a conditional equation, an identity, or a contradiction.

Goryan [66]

Since the equation is a true one, then it is an identity.

<h3>How to illustrate the information?</h3>

It should be noted that the information given is represented as 9(a−4)+3(2a+5)=7(3a−4)−6a+7.

After using the distributive law, the value that will be gotten will be:

15a - 21 = 15a - 21.

Therefore since the equation is a true one, then it is an identity.

Can you help me with this? I’ll mark brainliest

koban [17]

Answer:

Step-by-step explanation:

The step you need next is RQ = RQ.

When I learned this stuff, saying that RQ = RQ is the reflexive property.

Now you have

RP = RS Given

<PRQ = <SRQ The result of a bisected angle.

RQ = RQ A line is always equal to itself.

So the triangles are congruent. The rest follows as stated.
