a box with a square base and open top must have a volume of 512000 cm3 . find the dimensions of the box that minimize the amount of material used.
The box measures 100.79 cm by 100.79 cm by 50.40 cm in size, which minimizes the quantity of material used.
Given,
Let the side of the square base be x
h be the height of the box
Volume V = x²h
512000 = x²h
h = 512000/x² ..... 1
Surface area = x² + 2xh + 2xh
Surface area S = x² + 4xh ...... 2
Substitute 1 into 2;
From 2;
S = x² + 4xh
S = x² + 4x(512000/x²)
S = x² + 2048000/x
To minimize the amount of material used;
dS/dx = 0
dS/dx = 2x - 2048000/x²
0 = 2x - 2048000/x²
0 = 2x³ - 2048000
2x³ = 2048000
x³ = 1024000
x = ∛1024000
x = 100.79 cm
Since Volume = x²h
512000 = 100.79²h
h = 512000/10158.62
h = 50.40 cm
Hence the dimensions of the box that minimize the amount of material used is 100.79 cm by 100.79 cm by 50.40 cm

Is the sequence geometric if so identify the common ratio 1/3, 2/9, 4/27, 8/81
Answer:
It is a geometric sequence and the common scale factor is \(\frac{2}{3}\).
Step-by-step explanation:
In an arithmetic sequence, the difference between consecutive terms is always the same.
\(a_n=a_1+(n-1)d\)
where aₙ is the nth term, a₁ is the first term, n is the index, and d is the common difference.
In a geometric sequence, each consecutive term was multiplied by some factor over the last.
\(a_n=ax^n^-^1\)
where aₙ is the nth term, n is the index, and x is the scale factor.
In the given sequence, there is no common difference so it is not an arithmetic sequence. There is, however, a common scale factor applied to each consecutive term. Each term is multiplied by \(\frac{2}{3}\) over the last.
The formula for this sequence would be:
\(a_n=a\frac{2}{3} ^{n-1}\)
Answer:
r = \(\frac{2}{3}\)
Step-by-step explanation:
If the sequence is geometric then there will be a common ratio r between consecutive terms , that is
r = a₂ ÷ a₁ = a₃ ÷ a₂ = a₄ ÷ a₃
Then
a₂ ÷ a₁ = \(\frac{2}{9}\) ÷ \(\frac{1}{3}\) = \(\frac{2}{9}\) × 3 = \(\frac{2}{3}\)
a₃ ÷ a₂ = \(\frac{4}{27}\) ÷ \(\frac{2}{9}\) = \(\frac{4}{27}\) × \(\frac{9}{2}\) = \(\frac{2}{3}\)
a₄ ÷ a₃ = \(\frac{8}{81}\) ÷ \(\frac{4}{27}\) = \(\frac{8}{81}\) × \(\frac{27}{4}\) = \(\frac{2}{3}\)
Then sequence is geometric with common ratio r = \(\frac{2}{3}\)

***
Would water float on top of or sink
underneath rubbing alcohol?
sink underneath
float op top
220 PM
We know
if a object has higher d ensity than water then it would sink in water and if it has lower density than water then it float over waterClearly
79<100So alcohol would float over water
Water would sink underneath rubbing alcohol.
What is density?Density is the substance's mass per unit of volume.
A less dense substance floats on more dense substance.
Mathematically if density is ρ, mass is m and volume is V.
ρ = m/V g/ml
Now it is given that,
Density of Rubbing alcohol = 79 g/ml
Density of Water = 100 g/ml
So here we can see that,
Density of Water is more than Density of Rubbing alcohol
Thus Rubbing alcohol will float on the surface of water.
Thus, Water would sink underneath rubbing alcohol.

A circle on the coordinate plane has a diameter with endpoints at (6, 8) and (15, 8). Point (x, y) is the center of the circle. What is the value of x ?.
Answer: the value of x is 10.5.
Step-by-step explanation:The midpoint of a line segment with endpoints (x1, y1) and (x2, y2) is given by the coordinates [(x1 + x2)/2, (y1 + y2)/2].
In this case, the endpoints of the diameter of the circle are (6, 8) and (15, 8), so the midpoint of the diameter is [(6 + 15)/2, (8 + 8)/2] = (10.5, 8).
Since the midpoint of the diameter is the center of the circle, the coordinates of the center of the circle are (10.5, 8).
Therefore, the value of x is 10.5.

as the tides change, the water level in a bay varies sinusoidally. at high tide today at 8 a.m., the water level was 15 feet; at low tide, 6 hours later at 2 pm, it was 3 feet. how fast, in feet per hour, was the water level dropping at noon today?
The water level dropped from 15 feet at 8 A.M. to 3 feet at 2 P.M. The time interval between these two points is 6 hours. Therefore, the rate of change of the water level at noon was 2 feet per hour.
By analyzing the given information, we can deduce that the period of the sinusoidal function is 12 hours, representing the time from one high tide to the next. Since the high tide occurred at 8 A.M., the midpoint of the period is at 12 noon. At this point, the water level reaches its average value between the high and low tides.
To find the rate of change at noon, we consider the interval between 8 A.M. and 2 P.M., which is 6 hours. The water level dropped from 15 feet to 3 feet during this interval. Thus, the rate of change is calculated by dividing the change in water level by the time interval:
Rate of change = (Water level at 8 A.M. - Water level at 2 P.M.) / Time interval
Rate of change = (15 - 3) / 6
Rate of change = 12 / 6
Rate of change = 2 feet per hour
Therefore, the water level was dropping at a rate of 2 feet per hour at noon.

A graph shows the horizontal axis numbered 9 to 48. The vertical axis is numbered 1 to 5. The graph shows an upward trend from 1 to 33 then a downward trend from 33 to 45.
A graph shows the horizontal axis numbered 15 to 48. The vertical axis is numbered 1 to 5. The graph shows an upward trend from 1 to 30 then a downward trend from 30 to 45.
A graph shows the horizontal axis numbered 12 to 56. The vertical axis is numbered 2 to 8. The graph shows an upward trend from 1 to 32 then a downward trend from 32 to 56.
A graph shows the horizontal axis numbered 15 to 54. The vertical axis is numbered 1 to 5. The graph shows an upward trend from 1 to 24, a downward trend from 24 to 27, an upward trend from 27 to 30, a downward trend from 30 to 39, an upward trend from 39 to 45, a downward trend from 45 to 48, then an upward trend from 48 to 51.
To determine which set of data most likely has a mean closest to 29.5, we need to analyze the shape and position of the histograms in relation to the value 29.5.
Looking at the histograms described:
The first histogram ranges from 9 to 48, and the upward trend starts from 1 and ends at 33, followed by a downward trend. This histogram suggests that there may be values lower than 29.5, which would bring the mean below 29.5.
The second histogram ranges from 15 to 48, with an upward trend from 1 to 30 and then a downward trend. Similar to the first histogram, it suggests the possibility of values lower than 29.5, indicating a mean below 29.5.
The third histogram ranges from 12 to 56, and the upward trend starts from 1 and ends at 32, followed by a downward trend. This histogram covers a wider range but still suggests the possibility of values below 29.5, indicating a mean below 29.5.
The fourth histogram ranges from 15 to 54 and exhibits multiple trends. While it has fluctuations, it covers a wider range and includes both upward and downward trends. This histogram suggests the possibility of values above and below 29.5, potentially resulting in a mean closer to 29.5.
Based on the descriptions, the fourth histogram, with its more varied trends and wider range, is most likely to have a mean closest to 29.5.

Which ordered pair would be plotted by starting from the origin and moving 0. 25.
Depending on whether the movement is along the x-axis or the y-axis, the ordered pair would be either (0.25, 0) or (0, 0.25).
To plot an ordered pair starting from the origin and moving 0.25, we need both an x-coordinate and a y-coordinate.
We are starting from the origin (0, 0), we can apply the movement of 0.25 to either the x-axis or the y-axis.
If we move 0.25 units on the x-axis, the x-coordinate of the ordered pair would be 0.25, and the y-coordinate would remain 0 since there is no movement on the y-axis. Therefore, the ordered pair would be (0.25, 0).
Similarly, if we move 0.25 units on the y-axis, the x-coordinate would remain 0 since there is no movement on the x-axis, and the y-coordinate of the ordered pair would be 0.25. In this case, the ordered pair would be (0, 0.25).
