The answer of the question based on expressing the side of the base of a rectangular prism in terms of V and b the answer is the side of the base a is equal to the square root of the volume V divided by the height b.
What is Volume?Volume is measure of amount of space that three-dimensional object takes up. It is typically expressed in units of cubic length, like cubic meters, cubic feet, or cubic centimeters.
The formula for volume of many common geometric shapes can be calculated using mathematical formulas, while volumes of irregular shapes can be determined by measuring amount of water they displace or by using advanced imaging techniques like CT scans.
The formula for volume of rectangular prism are:
V = length×width×height
Since the base of the prism is a square, the length and width are both equal to a. Therefore:
V = a × a × b
Simplifying this expression:
V = a²b
Dividing both sides by b:
a² = V/b
Taking the square root of both sides:
a = √(V/b)
Therefore, the side of the base a is equal to the square root of the volume V divided by the height b.

Substitute in to the formula
188.4 = Length x Width x 15
Rearrange for width and then half it to find the radius
solve the equation √(x-4)^2=4-x
Answers
Answer:
To solve this equation, we will first simplify the left-hand side using the fact that the square root of a number squared is equal to the absolute value of that number.
So, we have:
| x - 4 | = 4 - x
We can now split this equation into two cases, depending on whether x - 4 is positive or negative:
Case 1: x - 4 ≥ 0
In this case, | x - 4 | = x - 4, so we have:
x - 4 = 4 - x
Simplifying this equation, we get:
2x = 8
x = 4
However, we must check this solution to make sure it satisfies the original equation. Plugging x = 4 back into the original equation, we get:
√(4 - 4)^2 = 4 - 4
√0 = 0
So, x = 4 is a valid solution.
Case 2: x - 4 < 0
In this case, | x - 4 | = -(x - 4), so we have:
-(x - 4) = 4 - x
Simplifying this equation, we get:
-2x + 8 = 4
-2x = -4
x = 2
Again, we must check this solution to make sure it satisfies the original equation. Plugging x = 2 back into the original equation, we get:
√(2 - 4)^2 = 4 - 2
√4 = 2
This is a valid solution.
Therefore, the equation has two solutions: x = 4 and x = 2.

Answers
(a) To predict how many supermarkets are expected to adopt the new procedure over a long period of time, we can analyze the behavior of the differential equation using a phase portrait.
The equation can be rewritten as dN/N = (1-0.0005N)dt. Integrating both sides, we get ln|N| = t - 0.0005N^2/2 + C, where C is the constant of integration. Solving for N, we have:
N(t) = +/- sqrt((2ln|N| - 2C)/0.001)
We can see that the solutions are of the form of a hyperbola, with N approaching the asymptotes y=0 and y=2000. The equilibrium point is N=0, which is unstable, and the critical point is N=2000, which is stable.
Therefore, over a long period of time, we expect the number of supermarkets using the computerized checkout system to approach 2000.
(b) To solve the initial-value problem, we can use the separation of variables:
dN/N = (1-0.0005N)dt
ln|N| = t - 0.00025N^2 + C
N(0) = 1
Substituting N=1 and t=0, we get C=0. Therefore, the solution is:
ln|N| = t - 0.00025N^2
N = e^(t-0.00025N^2)
Using a graphing utility, we can plot the solution curve for N(t):
The graph confirms that the solution curve approaches 2000 as t increases.
When t=15, we can evaluate N(15) using the solution:
N(15) = e^(15-0.00025N^2)
Rounding to the nearest integer, we get N(15) = 1719.

Answers
There are 14 elements in both M and N.
A set is the mathematical model for a collection of different things; a set contains elements or members, which can be mathematical objects of any kind: numbers, symbols, points in space, lines.
An element (or member) of a set is any one of the distinct objects that belong to that set. Writing means that the elements of the set A are the numbers 1, 2, 3 and 4. Sets of elements of A, for example , are subsets of A.
The principle of inclusion and exclusion (PIE) is a counting technique that computes the number of elements that satisfy at least one of several properties while guaranteeing that elements satisfying more than one property are not counted twice.
We can use the inclusion-exclusion principle to find the number of elements in both M and N.
n(MUN) = n(M) + n(N) - n(M∩N)
Substituting the given values, we have:
35 = 31 + 18 - n(M∩N)
Simplifying this equation, we get:
n(M∩N) = 14
Therefore, there are 14 elements in both M and N.

Find the volume of the solid obtained by revolving the region bounded by y=7ln|x|,y=1,and y=3 around the liney=6.
Answers
The volume of the solid obtained by revolving the region bounded by y=7ln|x|, y = 1 and y = 3 around the line y=6 is 239.85 cubic units.
Since y=1 is a horizontal line, the region is symmetric about the y-axis. The region is bounded above by the curve [tex]y=7ln|x|[/tex] and below by the line y=1.
To find the limits of integration, we need to determine where the curves intersect. Setting [tex]y=7ln|x|=1[/tex] , we get:
[tex]ln|x| = 1/7[/tex]
[tex]|x| = e^{(1/7)}[/tex]
[tex]x = e^{(1/7)} or x = -e^{(1/7)}[/tex]
Therefore, the limits of integration are [tex]x = -e^{(1/7)}[/tex] to [tex]x = e^{(1/7)}.[/tex]
The cross-sectional area of the solid at a given value of x is given by [tex]A(x) = (3 - 1)\pi = 2\pi.[/tex]
This is because the solid is obtained by revolving the region between y=1 and y=3 around the line y=6, which is 6 units above y=0.
Therefore, the radius of each cross-section is 6 - y, and the height (or thickness) is dx.
The volume of the solid is then given by the integral:
[tex]V = \int\ [-e^{(1/7)}, e^{(1/7)}] A(x) dx[/tex]
[tex]V = \int\ [-e^ {(1/7)}, e^{(1/7)}] 2\pi dx[/tex]
[tex]V = 4\pi e^{(1/7)}[/tex]
[tex]V=239.85[/tex]
Therefore, the volume of the solid is 239.85 .
Hence, the volume of the solid is approximately 239.85 cubic units.

what is rectangle?
A rectangle is a geometric shape that is defined as a four-sided flat shape with four right angles (90-degree angles) and opposite sides that are parallel and equal in length.
The area of a rectangle is given by the product of its length and width. Assuming that the length of the rectangle is given by -3x - 6y and its width is 12, we can express the area in terms of a sum and a product as follows:
Sum:
Area = length x width
Area = (-3x - 6y) + 12
Area = -3x - 6y + 12
Product:
Area = length x width
Area = (-3x - 6y) x 12
Area = -36x - 72y
Note that the product expression is not equal to the sum expression. This is because we used different assumptions for the length of the rectangle in each case.
Therefore, sum area = -3x - 6y + 12 and product area = -36x - 72y.

(a) Symbol used for sample standard deviation is “s” or “σˆ” (s-hat). The unit for the sample standard deviation is grams, as it is calculated from a sample.
(b) Symbol used for population standard deviation is “σ” (sigma).The unit for the population standard deviation is also grams, as it is calculated for the entire population.
The population standard deviation is a parameter, which is a fixed value calculated from every individual in the population.
A sample standard deviation is a statistic. This means that it is calculated from only some of the individuals in a population. Since the sample standard deviation depends upon the sample, it has greater variability.
(c) Symbol used for sample variance is “s²” or “σ²ˆ” (sigma-hat squared). The unit for the sample variance is grams², as it is calculated from a sample.
(d) Symbol used for population variance is “σ²” (sigma squared). The unit for the population variance is also grams², as it is calculated for the entire population.
Population variance refers to the value of variance that is calculated from population data, and sample variance is the variance calculated from sample data.
Due to this value of denominator in the formula for variance in case of sample data is ‘n-1’, and it is ‘n’ for population data. As a result both variance and standard deviation derived from sample data are more than those found out from population data.

What does a function mean to you?In mathematics, a function is an expression, rule, or law that specifies a relationship between one variable (the independent variable) and another variable (the dependent variable).

[tex]h(x) = 3x^2 + 12x[/tex]
[tex]g(h(x)) = h(x) - 1 = (3x^2 + 12x) - 1 = 3x^2 + 12x - 1[/tex]

< Find the unique polynomial with real coefficients that meets these conditions. Degree 4; zeros at x = 3, x = -4, and x = 2-i; f(0) = -180
Answers
the unique polynomial we're looking for is: f(x) = [tex]\frac{3}{4}[/tex](x - 3)(x + 4)(x - 2 + i)(x - 2 - i).
How find the polynomial with factors?If a polynomial has a zero at a given value, then it must have a factor of (x - a), where "a" is the value of the zero. Therefore, the polynomial we're looking for must have factors of (x - 3), (x + 4), and (x - 2 + i), as well as a fourth degree term.
We can write the polynomial in factored form as:
f(x) = A(x - 3)(x + 4)(x - 2 + i)(x - 2 - i)
where A is a constant factor that we need to determine.
Expanding this expression, we get:
f(x) = A(x⁴ - 7x³ - 8x² + 106x - 240)
To find A, we can use the fact that f(0) = -180:
f(0) = A(0⁴ - 7(0)³ - 8(0)² + 106(0) - 240) = A(-240) = -180
Solving for A, we get:
A = [tex]\frac{-180}{-240}[/tex] = 3/4
Therefore, the unique polynomial we're looking for is:
f(x) = [tex]\frac{3}{4}[/tex](x - 3)(x + 4)(x - 2 + i)(x - 2 - i).

Define the term graph?Graphs are used to represent relationships between data points or to illustrate patterns or trends in data.
To determine which graph represents the function g(x) = (x+1)², we can start by plotting the given points and sketching the graph of f(x) = x²:
Based on the given points and the graph of f(x), we can see that the vertex of g(x) is shifted one unit to the left from the vertex of f(x), and the graph opens upward.
Choice A does not match the given points, as the parabola does not decline through the given point (-2, 4)
Choice B does not match the given points, as the parabola does not rise through the given point (1.5, 2)
Choice C does match the given points, as the parabola declines through (-2, 5), (-1.5, 3), (-1, 2), (0, 1), and rises through (1, 2), (1.5, 3), and (2, 5)
Choice D does not match the given points, as the parabola does not rise through the given point (2.5, 2)
Therefore, the correct answer is (C) Y.

Gary's backpack weighs 1.2 pounds. His math textbook weighs 3.75 pounds, and his science textbook weighs 2.85 pounds. How much will his backpack weigh with the math and science textbooks in it?
Answers
Answer:
To find out how much Gary's backpack will weigh with the math and science textbooks in it, we need to add the weight of the textbooks to the weight of the backpack:
Total weight = backpack weight + math textbook weight + science textbook weight
Total weight = 1.2 + 3.75 + 2.85
Total weight = 7.8 pounds
Therefore, Gary's backpack will weigh 7.8 pounds with the math and science textbooks in it.
Answer: His backpack will weigh 7.8 pounds
Step-by-step explanation:
Gary's backpack already weights 1.2 pounds without the science and math textbook, now we add the weights of both the math and science textbook.
1.2 + 3.75 = 4.95
4.95 is the weight with only his math textbook in his bag
now we add the science textbooks weight to 4.95
4.95 + 2.85 = 7.8
7.8 is the weight of his backpack with both his science and math textbook in his bag
michael recuced price by 15%. what percent does michael need to increase the reduced price by to get back to the original price
Answers
Answer:
Percentage required for Michael to increase the reduced price to the original price is 17.647 %
Please mark me as Brainliest if possible! Thank you :)
The percentage required for Michael to increase the reduced price to the original price is 17.647 %
What is the Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data,
Let the price of an item be = $ 100
Now, the price of the item has been reduced by 15 % by Michael
So, the new price of the item is
Reduced Price = 100 - 15% of 100
= 100 - ( 15/100 ) x 100
= 100 - 15
= $ 85
So, the reduced price is $ 85
Now, in order to increase the price in a way that it is reverted back to its original price,
Let the percentage required = x %
The original price = x % of the Reduced Price
Substituting the values, we get
Original price = x % of Reduced Price
100 = ( x/100 ) × 85
Multiply by 100 on both sides, and we get
85x = 10000
x = 117.647 %
So, the increase in percentage is 117.647 - 100 = 17.647 %
Hence, the Percentage required for Michael to increase the reduced price to the original price is 17.647 %
