Evaluate the double integral. 4y2 dA, D is the triangular region with vertices (0, 1), (1, 2), (4, 1)
Answer:
44/3
Step-by-step explanation:
Let A be the line joining the vertices (0, 1) and (1,2) while B be the equation of the line joining (1, 2) and (4, 1).
The equation of a line joining points [tex](x_1,y_1) \ and\ (x_2,y_2)\ is:\\\\[/tex]
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]
The equation of line A joining (0, 1) and (1,2) is:
[tex]y-1=\frac{2-1}{1-0} (x-0)\\\\y-1=x\\\\x=y-1[/tex]
The equation of line D joining (1, 2) and (4,1) is:
[tex]y-2=\frac{1-2}{4-1} (x-1)\\\\y-2=-\frac{1}{3} (x-1)\\\\3y-6=-x+1\\\\x=-3y+7[/tex]
Therefore the change in y is: 1 ≤ y ≤ 2, while change in x is: y-1 ≤ x ≤ -3y + 7. Hence the double integral is:
[tex]\int\limits^2_1\int\limits^{-3y+7}_{y-1} {4y^2} \, dx dy\\\\=4\int\limits^2_1\int\limits^{-3y+7}_{y-1} {y^2} \, dx dy\\\\=4\int\limits^2_1y^2dy[x]^{-3y+7}_{y-1} \\\\=4\int\limits^2_1y^2dy(-3y+7-(y-1))\\\\=4\int\limits^2_1y^2dy(-4y+8)\\\\=4\int\limits^2_1(-4y^3+8y^2)dy\\\\=4[-y^4+\frac{8}{3}y^3 ]^2_1\\\\=4(\frac{11}{3} )\\\\=\frac{44}{3 }[/tex]
To answer this question, we need, first get the equations for the lines that enclosed the surface, and integrate according to the limits obtained from these equations give.
The solution is:
A = 44/3 square units
Let´s call points:
P ( 0 , 1 ) Q ( 1 , 2 ) and R ( 4 , 1 )
The equation for the line between, P and R is:
y = 1
The equation for the line between, P and Q is:
Slope-intercept equation is y = m×x + b
The slope m₁ = ( 2 - 1 ) / ( 1 - 0 ) m₁ = 1
and the line passes over the point x = 0 y = 1 ; then
1 = 0 +b b = 1
y = x + 1 ⇒ x = y - 1
The equation for the line between Q and R is:
m₂ = ( 1 - 2 ) / ( 4 - 1) m₂ = - 1/3
y = ( -1/3)× x + b
when x = 1 y = 2
2 = ( - 1/3)×(1) + b
2 + 1/3 = b
b = 7/3
y = - (x/3) + 7/3 ⇒ x = 7 - 3×y
The double integral becomes:
A = 4×∫∫ y² dx dy ⇒ A = 4 ×∫₁² y²dy ∫dx | (y - 1 ) y ( 7 - 3y)
A = 4×∫₁² y²dy × x | ( y - 1 ) y ( 7 - 3y)
A = 4 ×∫₁² y²dy × [ 7 - 3×y - ( y - 1 )]
A = 4 ×∫₁² y²dy × (8 - 4×y ) ⇒ A = 4 ×∫₁² (8×y² - 4×y³ ) dy
A = 4 × [ (8/3)×y³ - y⁴ | ₁²
A = 4 × [ 64/3 - 16 - (8/3) + 1 ]
A = 4 × ( 56/3 - 15 )
A = 4 × ( 56 - 45 /3)
A = 4 × 11/3
A = 44/3 square units

Step-by-step explanation:
A farmer uses x lb of fertilizer per acre at a cost of 1.4 per pound, leading to a revenue of R = 700 – 400e -x/100 dollars per acre.
(a) How many pounds of fertilizer should be applied per acre to maximize profit? Write you answer in decimal form rounding to three decimal places
Number
pounds per acre.
(b) What is the maximum profit on a 200 acre farm?
$ Number
Answer:
The cost can be written as:
C(x) = $1.4*x
The revenue can be written as:
R(x) = $700 - $400*e^(-x/100)
And as you know, the profit is written as the difference between the revenue and the cost:
P(x) = R(x) - C(x)
P(x) = $700 - $400*e^(-x/100) - $1.4*x
Now we want to maximize this, then we must look at the zeros in the derivate of P(x)
dP/dx = P'(x) = (-1/100)*$400*e^(-x/100) - $1.4
The maximum will be when P'(x) = 0.
we can solve:
0 = (-1/100)*$400*e^(-x/100) - $1.4
$1.4 = (-1/100)*$400*e^(-x/100)
(-100)*$1.4 = $400*e^(-x/100)
$140 = $400*e^(-x/100)
($140/$400) = e^(-x/100)
0.35 = e^(-x/100)
Now we can apply the Ln() in both sides and get:
ln(0.35) = ln(e^(-x/100) ) = -x/100
-ln(0.35)*100 = x = 104.98
You should apply 104.90 pounds of fertilizer.
b) The profit per acre, is:
P(x) = $700 - $400*e^(-x/100) - $1.4*x
Then if you have 200 acres, the profit will be:
200*P(x) = 200*($700 - $400*e^(-x/100) - $1.4*x)
and the maximum profit is whit x = 104.98 pounds, then:
200*P(104.98) = 200*($700 - $400*e^(-104.98/100) - $1.4*104.98) = $82,604.98
McKenzie told her friend, “If you increase my age by 8, multiply that quantity by 1/2 , and then subtract 6, you get 5.” Write an equation that matches McKenzie’s description using x as the variable.
a) x+8x1/2-6=5
b)1/2x+8-6=5
c)1/2(x+8-6)=5
d)1/2(x+8)-6=5
Answer:
D
Step-by-step explanation:
This follows PEMDAS
This first thing to do is add 8, so this must be P aka parentheses.
A and B are eliminated
Next is to M aka mutiply by 1/2
This eliminates C because if -6 was in the parentheses this would mean it is the next step as () takes priority. And this is not the case

Look at the bootom numbers. Look at the one and follow it up, the only lines that are not over two and are still above one are lines 3 and 4.
Answer:
Lines 3 and 4
Step-by-step explanation:
A slope is rise over run. So you have to determine how many you rise (go up) and run (go over). This is represented in a fraction form (such as 1/2 is up 1 and over 2). A slope greater than one would be 1/1 (go up more than one and over more than 1), and less than two (go up less than 2 and over less than 1).
Line 1 goes up 3 and over 1 (3/1 = a slope of 3)
Line 2 goes up 2 and over 1 (2/1= a slope of 2)
Line 3 goes up 3 and over 2 (3/2 = a slope of 1.5 )
Line 4 goes up slightly more than 1 and slight over 1
Line 5 goes up 1 and over 1 (1/1 = a slope of 1)

17=−13−8x
Answer:
x=-15/4 or -3.75
Step-by-step explanation:
17=−13−8x
30=-8x
x=30/-8 --> -15/4 or -3.75
Answer:
0.5
Step-by-step explanation:
It's simple really,
What you do is first add -13 from 17 and you get 4
17+-13=4
then you divide by 8 and you get 0.5.
4(divided by)8=0.5
Hope that helps you!
(If that's not the answer then do -0.5)
