A manufacturer wants to design an open-top box having a square base and a surface area of 120 square inches. what dimensions will provide a box with maximum volume?
The dimensions √30 inches square and 4 inches high will provide a box with maximum volume.
What are maxima and minima?The Maxima and minima of a function are the extremes within the range, in other words, the maximum value of a function at a certain point is called maxima and the minimum value of a function at a certain point is called minima.
It is given that:
A manufacturer wants to design an open-top box having a square base and a surface area of 120 square inches.
Let's suppose x is the base edge length and h is the box height.
x² + 4xh = 120
h = (120 - x²)/(4x)
h = 30/x - x/4
Volume = x²(30/x - x/4) = 30x - x³/4
dV/dx = 0
30 - x² = 0
x = √30
h = 120/x² = 120/30 = 4 inches
The box is √30 inches square and 4 inches high.
Thus, the dimensions √30 inches square and 4 inches high will provide a box with maximum volume.

What is the area of a triangle with vertices at (−4, 1) , (−7, 5) , and (0, 1) ? Enter your answer in the box. ___units²
In △ABC, the coordinates of vertices A and B are A(1,−1) and B(3,2). For each of the given coordinates of vertex C, is △ABC a right triangle?
Select Right Triangle or Not a Right Triangle for each set of coordinates.
C(0,2) right triangle or not a right triangle?
C(3,-1) right triangle or not a right triangle?
C(0,4) right triangle or not a right triangle?
Answer:
C(0,2) - Not A Right Angle
C(3,-1) - Right Angle
C(0,4) - Right Angle
I took the unit test and after this was the correct and answer. Hope this helps :))
Final answer:
To determine if △ABC is a right triangle, we can use the distance formula to calculate the lengths of the sides of the triangle. By comparing the squares of these lengths, we can determine if △ABC is a right triangle. For the given coordinates of vertex C, △ABC is not a right triangle.
Explanation:
To determine if △ABC is a right triangle, we need to check if the square of the length of the longest side is equal to the sum of the squares of the other two sides. Using the distance formula, we can find the lengths of AB and AC for each set of coordinates for vertex C. We then compare the squares of these lengths to determine if △ABC is a right triangle.
For C(0,2), the distance between A(1,-1) and C is √((0-1)^2 + (2-(-1))^2) = √(1 + 9) = √10. The distance between B(3,2) and C is √((0-3)^2 + (2-2)^2) = √(9 + 0) = 3. The longest side is AB with length √(2^2 + 3^2) = √(4 + 9) = √13. Since √13 is not equal to √10 + 3, △ABC is not a right triangle.
Following the same calculations for C(3,-1) and C(0,4), we find that △ABC is also not a right triangle for both cases. Therefore, the answer for all three sets of coordinates is Not a Right Triangle.

If PQ bisects CX at point J, and if JX = 4y and CJ = y+9 find y
By setting the given equations equal to each other (JX = CJ), we can create a new equation (4y = y +9). This equation simplifies to 3y = 9, giving a solution of y = 3.
Explanation:The problem you're facing deals with bisecting line segments, which is a topic under Geometry. Remember, if a segment bisects another, that means it divides the second segment into two equal parts. In this case, PQ bisects CX at point J, so JX = CJ.
We're also given that JX = 4y and CJ = y + 9. Because JX = CJ, we can set the two equations equal to each other and solve for y:
4y = y + 9
By subtracting y from both sides, we get
3y = 9
Finally, by dividing both sides by 3, we solve for y, which is 3

Why, if two wrongs don't make a right, do two negatives make a positive in mathematics?
So, we can’t directly compare wrong with that of negative. Let me give an example. Let’s just think of Terrorism. Do you think there are positive and negative sides of terrorism? Mostly the answer would be no. There is no such things as positive and negative when we think of terrorism. But here we can directly say that Terrorism is always wrong whenever and wherever we talk about it.
I think now I have cleared your doubts about difference between wrong and negative. That’s why we can never say that two wrong can make a right. I hoped this helped!!
Final answer:
In mathematics, two negatives make a positive due to the rules of multiplication and addition. This rule is a fundamental property of mathematics and is consistent across various mathematical operations and contexts.
Explanation:
In mathematics, two negatives make a positive due to the rules of multiplication and addition. When two negatives are multiplied, the negative signs cancel each other out and result in a positive product. For example, (-4) x (-3) = 12, where both numbers are negative but the product is positive.
The same concept applies to addition as well. When two negative numbers are added, the negative signs combine and result in a negative sum. However, when two negative numbers are multiplied, the negative signs cancel out and produce a positive product.
It's important to note that this rule is a fundamental property of mathematics and is consistent across various mathematical operations and contexts.

What are the excluded values of x for x^2-9x/x^2-7x-18
The excluded values of x for x^2-9x/x^2-7x-18 are -2 and 9
The expression is given as:
x^2-9x/x^2-7x-18
Set the denominator of the expression to 0
x^2-7x-18 = 0
Expand the above expression
x^2 + 2x -9x -18 = 0
Factorize the expression
x(x + 2) -9(x +2) = 0
Factor out x + 2
(x -9)(x +2) = 0
Solve for x
x = 9 and x = -2
Hence, the excluded values of x for x^2-9x/x^2-7x-18 are -2 and 9

Step-by-step explanation:Problem 1
cos(angle) = adjacent/hypotenuse
cos(18) = x/25
25*cos(18) = x
x = 25*cos(18)
x = 23.7764129073789
x = 23.78
Answer: x = 23.78

Problem 2
theta = greek letter that looks like a "zero" or the letter O with a horizontal line through it
With the reference angle of theta, the opposite side is 3. This side is the leg furthest from the angle theta. In contrast, the side 4 is the closest leg to theta. The longest side 5 is the hypotenuse. The hypotenuse is always the lonest side
sin(theta) = opposite/hypotenuse
sin(theta) = 3/5
cos(theta) = adjacent/hypotenuse
cos(theta) = 4/5
tan(theta) = opposite/adjacent
tan(theta) = 3/4
---------------------------
In summary:
sin(theta) = 3/5
cos(theta) = 4/5
tan(theta) = 3/4
=====================================================
Problem 3
cos(angle) = adjacent/hypotenuse
cos(x) = 15/29
x = arccos(15/29) .... inverse cosine or cos^(-1) also works
x = 58.852610078491
x = 58.85
Answer: x = 58.85
=====================================================
Problem 4
The rule we'll use is
sin(x) = cos(90-x)
sin(theta) = cos(90-theta)
cos(90-theta) = cos(58)
90 - theta = 58
90 - theta+theta = 58+theta
90 = 58+theta
90-58 = 58+theta-58
32 = theta
theta = 32
Answer: 32
=====================================================
Problem 5
x = height of pole
the vertical side is the side we want, which is the opposite side compared to the angle 55 degrees
sin(angle) = opposite/hypotenuse
sin(55) = x/25
25*sin(55) = x
x = 25*sin(55)
x = 20.4788011072248
x = 20.5
Each pole is roughly 20.5 feet tall.

A cookie factory uses 3/8 of a barrel of oatmeal in each batch of cookies with the factor uses 3/4 of a barrel of oatmeal yesterday how many batches of cookies did the factory make
The cookie factory made 2 batches of cookies yesterday. This is found by dividing the total amount of oatmeal used (3/4 of a barrel) by the amount used per batch (3/8 of a barrel).
Explanation:To find the number of batches of cookies the factory made, we would divide the total amount of oatmeal used by the amount used per batch.
The factory used 3/4 of a barrel of oatmeal yesterday, and each batch uses 3/8 of a barrel. So, we divide 3/4 by 3/8.
Before doing that, remember that dividing by a fraction is the same as multiplying by its reciprocal. The reciprocal of 3/8 is 8/3.
So, 3/4 divided by 3/8 is equivalent to 3/4 multiplied by 8/3, giving us a result of 2.
Therefore, the cookie factory made 2 batches of cookies yesterday using 3/4 of a barrel of oatmeal.
