The value of the double integral is 13 times ∬S (x + y) dA = 13(15) = 195.
We can first find the region R in the uv-plane that corresponds to the square S in the xy-plane using the transformation:
x = 2u + 3v
y = 3u - 2v
Solving for u and v in terms of x and y, we get:
u = (2x - 3y)/13
v = (3x + 2y)/13
The vertices of the square S in the xy-plane correspond to the following points in the uv-plane:
(0, 0) -> (0, 0)
(2, 3) -> (1, 1)
(5, 1) -> (2, -1)
(3, -2) -> (1, -2)
Therefore, the region R in the uv-plane is the square with vertices (0, 0), (1, 1), (2, -1), and (1, -2).
Using the transformation, we have:
x + y = (2u + 3v) + (3u - 2v) = 5u + v
The double integral becomes:
∬S (x + y) dA = ∬R (5u + v) |J| dA
where |J| is the determinant of the Jacobian matrix:
|J| = |∂x/∂u ∂x/∂v|
|∂y/∂u ∂y/∂v|
= |-2 3|
|3 2|
= -13
So, we have:
∬S (x + y) dA = ∬R (5u + v) |-13| dudv
= 13 ∬R (5u + v) dudv
Integrating with respect to u first, we get:
∬R (5u + v) dudv = ∫[v=-2 to 0] ∫[u=0 to 1] (5u + v) dudv + ∫[v=0 to 1] ∫[u=1 to 2] (5u + v) dudv
= [(5/2)(1 - 0)(0 + 2) + (1/2)(1 - 0)(2 + 2)] + [(5/2)(2 - 1)(0 + 2) + (1/2)(2 - 1)(2 + 1)]
= 15
Therefore, the value of the double integral is 13 times this, or:
∬S (x + y) dA = 13(15) = 195
So, the answer is (E) none of the above.

Ben is standing 8 feet from
the base of a telephone pole.
The angle of elevation from the
point on the ground where he is
standing to the top of the pole
is 62°. Find the height of the
telephone pole. Round to
the nearest tenth.
Answer:
Approximately 15.05 ft
Step-by-step explanation:
You need to use tangent for this question.
Since tan θ = [tex]\frac{Opposite}{Adjacent}[/tex]
to find the Opposite, we need to rearrange the equation to:
Adjacent × tan θ = Opposite.
So if you insert 62 for θ and 8 feet for Adjacent, you will get:
8 × tan(62) = Opposite.
and you will get approximately 15.05 feet for your Opposite side
a rectangular garden measures 22.7 m by 16.6 m how many meters of fencing materials are needed to enclose it the fencing materials cost 12.50 per meter
Answer:
78.6m of fencing
That would cost $982.50
Step-by-step explanation:
Perimeter: 2(22.7)+2(16.6)=P
P = 78.6
Cost: 78.6*12.50
C = 982.50
A room has a perimeter of 40 feet. The length is 4 less than 2 times the width. What are the dimensions of the room?
Answer:
First, develop an equation for this scenario. The formula to find the perimeter of a quadrilateral is 2l+2w. Because the length is 4 less than twice the width, this would be translated to (2w-4). Plug this into the variable for the length to get 2(2w-4)+2w=40. Distribute the 2 to get 4w-8+2w=40. Add the like terms to get 6w-8=40. Add 8 to both sides and get 6w=48. Divide 6 to result with w=8.
Now that we know w, we can substitute 8 into the variable to solve for the length. 2l+2(8)=40. Multiply 8 and 2 to get 2l+16=40. Subtract 16 to both sides to get 2l=24. Divide 2 to both sides to result with l=12.
Length = 12 feet
Width = 8 feet

Answer:
All sides are parallel.

Answer:
y=5x+11
Step-by-step explanation:
The table shows the participation in a school’s debate club during the last four years. Year 1 2 3 4 Students 14 19 25 33 Between which two years did the club see the greatest growth? By what percent did it grow? Round to the nearest percent. Use the drop-down menus to show and explain your answer. The greatest growth was between years Choose... and Choose... . The growth between those years was about Choose... .
Answer:
Year 1 and 2
36%
Step-by-step explanation:
Given the data :
Year ______1 ___ 2 ____ 3 ___ 4
Students __ 14 __ 19 ___ 25 __ 33
Greatest growth is observed between year 1 and 2
Growth percent :
(year 2 - year 1) / year 1 * 100%
(19 - 14) / 14 * 100%
5 / 14 * 100%
0.3571 * 100%
= 35. 71%
= 36%
The growth percent between year 1 and 2 is greater than between the other years
Year 2 and 3 = (6/19) * 100% = 31.57%
Year 3 and 4 = (8/25) * 100% = 32%
Answer:
1 and 2 x=32%
Step-by-step explanation:
1. 5/14=x/100
2. 500/14=14x/14
so you get 36%

Does the point (6, 0) satisfy the equation y = x + 6?
yes or no
Answer:
No.
Step-by-step explanation:
You have to replace the (6,0) with the equation at hand. So, since 6 is in the X spot and 0 is in the Y spot, the equation would then look like 0=6+6. The equation is false as you can see.
No, this point does not lie on the line y = x + 6.
What is the general equation of a Straight line?
The general equation of a straight line is -
y = mx + c[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.Other possible equations of lines are -
(y - y₁) = m(x - x₁) {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁) {Two point - slope form}x/a + y/b = 1 {intercept form}x cos(β) + y sin(β) = L {Normal form}We have the equation of line as -
y = x + 6
For point (6, 0), we can write -
0 = 6 + 6
0 ≠ 12
Therefore, no, this point does not lie on the line -
y = x + 6
