The first thing we are going to do for this case is define variables.
We have then:
w: width
l: length
The perimeter is given by:
[tex] 2w + 2l = 520
[/tex]
The area is given by:
[tex] A = w * l
[/tex]
The area as a function of a variable is:
[tex] A (w) = w * (260-w)
[/tex]
Rewriting we have:
[tex] A (w) = -w ^ 2 + 260w
[/tex]
To obtain the maximum area, we derive:
[tex] A '(w) = -2w + 260
[/tex]
We equal zero and clear the value of w:
[tex] -2w + 260 = 0
2w = 260
[/tex]
[tex] w = \frac{260}{2}
w = 130
[/tex]
Then, the length is given by:
[tex] l = 260 - w
l = 260 - 130
l = 130
[/tex]
Finally, the maximum area obtained is:
[tex] A = w * l
A = 130 * 130
A = 16900
[/tex]
Answer:
A retangle that maximizes the enclosed area has a length of 130 yards and a width of 130 yards.
The maxium area is 16900 square yards

A total of 411 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was two times the number of adult tickets sold. How many adult tickets were sold?
The number of tickets sold to adults is 274 and of tickets sold to students is 137.
What is the system of equations?A system of equations is a set of one or more equations involving a number of variables.
Let the number of tickets sold to adults be x.
And the number of tickets sold to students be y.
A total of 411 tickets were sold for the school play.
x + y = 411
The number of student tickets sold was two times the number of adult tickets sold.
x = 2y
Substitute the value of x in equation 1
[tex]\rm x + y = 411\\\\2y+y=411\\\\3y=411\\\\y =\dfrac{411}{3}\\\\y= 137[/tex]
Substitute the value of y in equation 2
[tex]\rm x = 2y\\\\x= 2\times 137 \\\\x =274[/tex]
Hence, the number of tickets sold to adults is 274 and of tickets sold to students is 137.

What is the least common denominator of 5/12 and 4/9
Every ten years, the Bureau of the Census counts the number of people living in the United States. In 1790, the population of the U.S. was 3.93 million. By 1800, this number had grown to 5.31 million. Write an exponential function that could be used to model the U.S. population y in millions for 1790 to 1800. Write the equation in terms of x, the number of decades since 1790.
Which function represents exponential decay?
f(x) =1/2 (3/2)^x
f(x) =1/2 (-3/2)^x
f(x) =4 (-2/3)^x
f(x) = 4 (2/3)^x
The function [tex]f(x) = 4 (2/3)^x[/tex] represents exponential decay, as the base of the exponent (2/3) is between 0 and 1.
The function which represents exponential decay is the one where the base of the exponent is between 0 and 1 (0 < b < 1). Out of the given options, [tex]f(x) = 4 (2/3)^x[/tex] represents an exponential decay function since (2/3) is a positive fraction less than 1.
In contrast, a base greater than 1, a negative base, or a base of 1 would not represent decay: a base greater than 1 represents exponential growth; a base of 1 would be constant (no growth or decay); and a base that is negative would not be a standard exponential decay because it would lead to oscillation between positive and negative values.

The location of Q in the rectangle is D. (4, 3).
How to illustrate the information?
Graph images undergo transformations, one of the types of transformations is rotations. Rotation is done when each point of the image rotates 90° around a point in a counterclockwise manner.
When rotation is done, (x,y) -> (-y,x), therefore when taking points from image to original then the reverse is done (-y,x) --> (x,y)
The coordinates of image point q' is (-3,4), hence, before rotation then the coordinates are (4,3).

Choose the relationship symbol that makes the statement true.
Answer:
The relationship symbol that makes the statement true is '>'.
Step-by-step explanation:
Given,
In triangles ABC and EDF,
∠A = ∠D
Since, the sum of all interior angles of a triangle is supplementary,
⇒ ∠A + ∠B + ∠C = 180° and ∠D + ∠E + ∠F = 180°
⇒ ∠A = 180° - ∠B - ∠C and ∠D = 180° - ∠E - ∠F,
By substituting the values,
180° - ∠B - ∠C = 180° - ∠E - ∠F
- ∠B - ∠C = - ∠E - ∠F
∠B + ∠C = ∠E + ∠F
∠B + 20° = ∠E + 30° ( given ∠C = 20° and ∠F = 30° )
∠B = ∠E + 10°
⇒∠B > ∠E
Hence, the relationship symbol that makes the statement true would be '>'.

Find the most general antiderivative of the function.
g(t) = (5 + t + t^2)/ square root of t
To find the most general antiderivative of the function g(t) = (5 + t + t^2) / sqrt(t), rewrite the function using inverse trigonometric functions and integrate it with respect to x, before substituting x back in terms of t to get the most general antiderivative.
Explanation:To find the most general antiderivative of the function, g(t) = (5 + t + t^2) / sqrt(t), we can rewrite the function using inverse trigonometric functions. Let x = sqrt(t), then t = x^2. Substituting this into the function gives us g(x^2) = (5 + x^2 + x^4) / x. Now, we can integrate this function with respect to x to find the antiderivative. The antiderivative of (5 + x^2 + x^4) / x is 5x + (x^3/3) + (x^5/5) + C, where C is the constant of integration. Finally, we substitute x back in terms of t to get the most general antiderivative of g(t).

Rishi Maharan’s charge account statement shows an unpaid balance of $6,752.22. The monthly finance charge is 1.85% of the unpaid balance. After the finance charge was applied, Rishi has made new purchases of $150.75. What is the new account balance?
$7,027.89
$7,030.67
$6,902.97
$6,877.14
The requreid new account balance is approximately $7,027.89, which is option A.
What is a finance charge?A finance charge is a fee charged by a lender or creditor for the use of credit or the extension of existing credit. It is typically calculated as a percentage of the unpaid balance on a credit account or loan and is added to the account balance as an additional cost to the borrower.
The finance charge can be calculated as:
1.85% of $6,752.22 = 0.0185 x $6,752.22 = $124.98
Adding this finance charge to the unpaid balance gives:
$6,752.22 + $124.98 = $6,877.20
Finally, adding the new purchases to this balance gives:
$6,877.20 + $150.75 = $7,027.95
So, the new account balance is approximately $7,027.89, which is option A.
