Evaluate the double integral ∬Ry2x2+y2dA, where R is the region that lies between the circles x2+y2=16 and x2+y2=121, by changin
olga2289 [7]

Answer:

See answer and graph below

Step-by-step explanation:

∬Ry2x2+y2dA

=∫Ry.2x.2+y.2dA

=A(2y+4Ryx)+c

=∫Ry.2x.2+y.2dA

Integral of a constant ∫pdx=px

=(2x+2.2Ryx)A

=A(2y+4Ryx)

=A(2y+4Ryx)+c

The graph of y=A(2y+4Ryx)+c assuming A=1 and c=2

Find two numbers whose sum is 15 and the product is 36
ycow [4]
The two numbers are 3 and 12.

I got these numbers by factoring 36.

1 * 36    sum : 37
2 * 18    sum : 20
3 * 12    sum : 15

It is easier to find the factor of a number and solve for the sum. Than to find the addends of a number and solve for the product.

There are 9 factors of 36 while 14 addends of 15.

Enter the equation of the line in slope-intercept form.
goblinko [34]

Answer:

y=5x-23

Step-by-step explanation:

Slope-intercept form is: y=mx+b

'm' is the slope.

'b' is the y-intercept.

<h3>What we know:</h3>
  • We are given the slope of 5.
  • We are given a coordinate. (5,2)
<h3>What we need to do:</h3>
  • We will use the coordinate and the slope to complete the equation.
<h3>Solving The Equation:</h3>

We are already given the slope of five. So, m = 5.

We are given a coordinate. So, to solve the y-intercept, we will use:

x = 5

y = 2

2=5(5)+b\\\rightarrow5*5 =25\\2=25+b\\\rightarrow 2-25=25-25+b\\\boxed{-23=b}

So, the y-intercept should be -23.

<h3>Your answer should be:</h3>

y=5x-23
