What is volume?Volume is the measure of the capacity that an object holds.
Formula for the volume of cuboidvolume = length × breadth × height
According to the given question
We have
A box with the open top and square base.
Let x be the side of the box. And h be the height of the box
Also, the cost of material for the base is $8 and for side is $2 per square foot.
The total cost of material for the box is $2400
⇒[tex]8x^{2} + 4(2xh) = 2400[/tex]
⇒ [tex]8x^{2} + 8xh = 2400\\[/tex]
⇒[tex]x^{2} + xh = 300[/tex]
⇒ [tex]h = \frac{300-x^{2} }{x}[/tex]
Therefore,
volume of the box
[tex]= x^{2} h[/tex]
= [tex]x^{2} \frac{3000-x^{2} }{x}[/tex]
= [tex]x(300-x^{2} )[/tex]
= [tex]300x - x^{3}[/tex]
for the maximum volume,[tex]\frac{d}{dx}(v)=0[/tex]
⇒ [tex]300 - 3x^{2} =0[/tex]
⇒[tex]300 = 3x^{2}[/tex]
⇒ [tex]x^{2} =100[/tex]
⇒ x = ± 10
⇒ x= 10 feet (x = -10 not possible)
So, h = [tex]\frac{300-100}{10} = 20feet[/tex]
Hence, the height and side of the box for the maximum volume are 20 feet and 10 feet respectively.

Type the correct answer in each box. If necessary, round your answer(s) to the nearest hu The vertices of AABC are A(-2, 2), B(6, 2), and C(0, 8). The perimeter of AABC is
Answer:
22.81
Step-by-step explanation:
The distance formula can be used to find the distances between pairs of vertices. The perimeter is the sum of those distances.
Side lengthsThe distance formula is ...
d = √((x2 -x1)^2 +(y2 -y1)^2)
Using this formula the triangle side lengths are ...
AB = √((6 -(-2))^2 +(2 -2)^2) = √(8^2) = 8
BC = √((0 -6)^2 +(8 -2)^2) = √(6^2 +6^2) = 6√2
CA = √((-2 -0)^2 +(2 -8)^2) = √(4 +36) = √40
The perimeter of the triangle is the sum of these lengths:
P = 8 +6√2 +2√10 ≈ 22.8098
The perimeter is about 22.81 units.

Levada borrows $30,900 from her bank to open a florist shop. She agrees to repay the money in 18 months with simple annual interest of 5.5%
Levada borrows $30,900 from her bank to open a florist shop at rate of 0.98% per month.
How to calculate simple interest amount?If the initial amount (also called as principal amount) is P, and the interest rate is R% annually, and it is left for T years for that simple interest, then the interest amount earned is given by:
[tex]I = \dfrac{P \times R \times T}{100}[/tex]
It is given that Levada borrows $30,900 from her bank to open a florist shop. She agrees to repay the money in 18 months with simple annual interest of 5.5%.
P = $30,900
T = 18 months
Interest = 5.5%
Interest rate = P×R×T
5.5 = 30,900 × R × 18
R = 0.000988

Compute the monthly payments for each add-on interest loan. The amount of the loan is $1150. The annual interest rate is 6%. The term of the loan is 4 years
The monthly payments for each add-on interest loan is computed to be $29.71.
Given Information and Formula Used
Principal Amount of the loan, P = $1150
Rate of Interest of the loan, R = 6%
Term of loan in years, T = 4
The formula for simple interest is given as follows,
I = (P × R × T)/100
The formula for amount of add-on interest loan is given by, A = P + I
Calculating the Interest of the Loan
Interest of the loan, I = (P × R × T)/100
Now, substituting the given values of P, R, and T in the above formula, we get,
I = $ (1150 × 6 × 4)/100
I = $ 27600/100
I = $276
Calculating the Total Monthly Payment for the Loan
Amount of loan, A = P+I
A = $1150 + $276
A = $1426
Monthly payment of the loan with interest = A/(4×12)
= $ 1426/48
= $29.71
Thus, the monthly payments for each add-on interest loan comes out to be $29.71.

The attached figure represents the image of A"B"C" after the transformation
How to transform the triangle?The transformation rule is given as:
A"B"C" = Ro90° (T(-4,3)(ABC))
This means that we rotate the triangle 90 degrees clockwise, and then translate the triangle
From the figure, the coordinates of ABC are
A = (-1, 2)
B = (1, 4)
C = (3, -1)
The rule of 90 degrees clockwise rotation is
(x,y) ⇒ (y,-x)
So, we have
A' = (2, 1)
B' = (4, -1)
C' = (-1, -3)
The translation of the triangle by T(-4,3) is
(x,y) ⇒ (x - 4, y + 3)
So, we have
A'' = (-2, 4)

The value of x in the similar triangles is 18
How to solve similar triangles?Similar triangles have the same shapes but may have different sizes.
Corresponding side of similar triangles are a ratio of each other.
Therefore,
UV / BC = AU / AB
Hence,
UV = 444 units
BC = 703
AU = 20x + 108
AB = 20x + 108 + 273 = 20x + 381
Therefore,
