ANSWER

The area of the floor is 696 square feet.

EXPLANATION

It was given that, the volume inside a rectangular storage room is 2,088 cubic feet.

The rectangular room is a rectangular prism.

The volume of a rectangular prism is

[tex]V = floor \: area \times height[/tex]

The height of the room is 3 ft.

This implies that,

[tex]2088= floor \: area \times3[/tex]

Divide both sides by 3.

[tex] \frac{2088}{3} = floor \: area [/tex]

[tex]floor \: area = 696 {ft}^{2} [/tex]

The area of the floor is 696 square feet.

Answer:

B. False

Step-by-step explanation:

Given an equation of the type x = a(y-x)^2 + h, We know that If the "y" is squared, it is horizontal (opens left or right). If a is positive, the parabola opens up or to the right. If it is negative, it opens down or to the left.

Like the y is squared and the "a" is positive then it opens to the right, so it's false

Answer:what is the table

Step-by-step explanation:

Answer:

24 π

Step-by-step explanation:

First step is to determine the radius of the base.  We have the area, so we can easily determine the radius.  The base is a circle, and the area of a circle is given by A = π * r² , so r² = A / π

r² = (36 π) / π = 36

So, r = 6

The lateral surface of a cylinder is given by the following:

L = 2* π * r * 2

Now that we have r, we can easily calculate it:

L = 2 * π * 6 * 2 = 24π, second choice listed

Answer:

The result [tex]6x^4-x^3-19x^2+2x+12[/tex].

Step-by-step explanation:

The first polynomial is [tex]3x^2-2x-4[/tex].

The second polynomial is [tex]2x^2+x-3[/tex]

The closure property of multiplication states that if we multiply two polynomials the result must be a polynomial.

The product of these two polynomials is :

The volume of a cylinder with a height of 8 and a radius of 3.8 is 115.52π cubic units, and with a height of 14 and a radius of 5, it is 350π cubic units.

The formula for the volume of a cylinder is V = πr²h, where r is the radius and h is the height of the cylinder.

For question 4 with a height of 8 and a radius of 3.8, the volume would be: V = π(3.8)²(8) = 115.52π cubic units.

For question 5 with a height of 14 and a radius of 5, the volume would be: V = π(5)²(14) = 350π cubic units.

These calculations illustrate how to determine the volume of cylinders using their respective dimensions, providing a fundamental understanding of geometric principles and applications.

Answer: Derrick’s mean test score= 74.4

Derrick’s median test score = 81.5

Better picture of his scores is given by Median.

Step-by-step explanation:

The given data : 25, 40, 68, 85, 95, 98, 70, 78, 85, 100

[tex]\text{Mean}=\dfrac{\text{Sum of all observations}}{\text{Number of observations}}\\\\\Rightarrow\ \text{Mean}=\dfrac{744}{10}=74.4[/tex]

For Median , Arrange the data in order

The question doesn't provide enough information to answer it properly, as it doesn't specify the polynomial or the divisor necessary for synthetic division. Synthetic division involves dividing a polynomial by a linear divisor, but without the set polynomial and divisor, the number that would belong in the place of the question mark can't be determined.

Unfortunately, the information provided doesn't clearly indicate the format or context of a synthetic division problem. Synthetic division typically involves dividing a polynomial by a linear divisor. The elements of the polynomials are numbers, specifically the coefficients of the polynomial terms. The repetition in your question about various Car X, Car Y and dots at various hash marks appears to be irrelevant data as it does not correlate with the synthetic division problem.

However, to apply synthetic division, we would need a specific polynomial to carry out the process. In synthetic division, a box is drawn, the coefficients of the polynomial are written in that box, and then the divisor is placed outside the box. From there, the numbers inside the box are manipulated, in a step-by-step manner, based on the divisor. The numbers derived from this process are the coefficients of the answer. Without this specific data, we cannot accurately determine what number belongs in the place of the question mark.

Answer:

The probability that exactly one switch is good is

[tex]P(x) =0.0392[/tex]

Step-by-step explanation:

The probability that a switch is defective is:

[tex]P(D) = \frac{2}{100} =0.02[/tex]

The probability that a switch is not defective is

[tex]P(D') = 1-P(D)=0.98[/tex]

Therefore, if two switches are selected, the probability that exactly 1 is good is:

[tex]P(1=1)=P (D) P (D ') + P (D') P (D)[/tex]

[tex]P(x)=(0.02)(0.98) + (0.98)(0.02)[/tex]

[tex]P(x) =0.0392[/tex]

Answer:

P (exactly one good switch) = 0.0392

Step-by-step explanation:

We know that 2% of all switches are defective.

P (defective) = [tex]\frac{2}{100} =0.02[/tex]

So P (not defective) = 1 - P (defective) = [tex]1-0.02=0.98[/tex]

Now we have to find the probability of one good switch out of 2 that are used in a device.

P (exactly one good switch) = [tex] (0.02 \times 0.95) + (0.02 \times 0.95) [/tex] = 0.0392

Answer:

V = 3408 pi  unit^3

Step-by-step explanation:

Volume  of a cone is given by

V = 1/3 pi r^2 h

We know the radius is 12 and the height is 71

V = 1/3 * pi * (12)^2 *71

V = 1/3 * pi * 144 *71

V = 3408 pi  unit^3

Answer:

[tex]Volume=3408 \pi[/tex] [tex]units^3[/tex]

Step-by-step explanation:

Given that radius of the cone is r = 12 units

Given that height of the cone is h = 71 units

Now question says to find the volume of the given cone.

So plug these values into formula of volume of the cone.

[tex]Volume=\frac{1}{3}\pi r^2h[/tex]

[tex]Volume=\frac{1}{3}\pi (12)^2(71)[/tex]

[tex]Volume=\frac{1}{3}\pi (144)(71)[/tex]

[tex]Volume=\frac{1}{3}\pi (10224)[/tex]

Answer:

Step-by-step explanation:

The actual definition of a fractional equation could be:

[tex]\frac{a}{x}+\frac{b}{x+1}=c[/tex]

In words, fractional equations are those which has variables in the denominator of a fractional term, that doesn't mean that all fractions must have a unknown denominator, but at least one of the denominators should have a variable.

Therefore, according to its definition, the right answer is third option.

In addition, other options don't make sense, multiple variables is not necessarily the case for fractional equations. Similarly, not all denominators must have variables. And, having variable only in the numerators don't define the equation as fractional.

The graph of [tex]y=cos(x)[/tex] is:

*Stretched vertically by a factor of 3

*Compressed horizontally by a factor  [tex]\frac{1}{10}[/tex] .

*Moves horizontally [tex]\pi[/tex] units to the rigth

The transformation is:

[tex]y=3f(10(x-\pi))[/tex]

Step-by-step explanation:

If  the function [tex]y=cf(h(x+b))[/tex]  represents the transformations made to the graph of [tex]y= f(x)[/tex]  then, by definition:

If  [tex]0 <c <1[/tex] then the graph is compressed vertically by a factor c.

If  [tex]|c| > 1[/tex] then the graph is stretched vertically by a factor c

If [tex]c <0[/tex]  then the graph is reflected on the x axis.

If [tex]b> 0[/tex] The graph moves horizontally b units to the left

If [tex]b <0[/tex] The graph moves horizontally b units to the rigth

If [tex]0 <h <1[/tex] the graph is stretched horizontally  by a factor [tex]\frac{1}{h}[/tex]

If [tex]h> 1[/tex] the graph is compressed horizontally by a factor [tex]\frac{1}{h}[/tex]

In this problem we have the function [tex]y=3cos(10(x-pi))[/tex] and our parent function is [tex]y = cos(x)[/tex]

The transformation is:

[tex]y=3f(10(x-\pi))[/tex]

Then [tex]c =3>1[/tex]  and [tex]b =-\pi < 0[/tex] and [tex]h=10 > 1[/tex]

Therefore the graph of [tex]y=cos(x)[/tex] is:

Stretched vertically by a factor of 3.

Also as [tex]h=10[/tex] the graph is compressed horizontally by a factor  [tex]\frac{1}{10}[/tex] .

Also, as [tex]b =-\pi < 0[/tex] The graph moves horizontally [tex]\pi[/tex] units to the rigth

By my definition, no. There's a continuity up to and including just before 1 approaching from the left, and there's a continuity just after 1 going to the right. But 1 itself has a special definition h(x) = 4 when x = 1 and that makes it discontinuous.

To solve the inequalities by graphing, transform each inequality into an equation form, plot the lines on the graph, and identify the overlapping region that satisfies both inequalities. The lines are 5x + 2y ≥ 3 and y ≥ x, with appropriate slopes and y-intercepts.

To solve the inequalities by graphing, we need to transform each inequality into a graphable equation form and then use the properties of the lines to find the solution set. The inequalities in question are:

Let's graph each inequality one by one:

The solution to the system of inequalities will be the region on the graph where both conditions are satisfied, typically above the lines in this case because both inequalities are greater than or equal to.

Always label your graph with f(x) and x, and select an appropriate scale for the x and y axes to ensure all important points and lines are visible on the graph.

The provided figures and instructions on slope and graphing help us understand how to plot each line based on their equations. Using the slope-intercept form, we graph the lines and identify the intersection or overlapping regions that satisfy both inequalities.

Step-by-step explanation:

I did the test

roughly 1.5

since it says the limit as x approaches 2- it means that you are going from the left (from the negative ie 2-). If it said 2+ you would go from the right. So you should start on the left at the end of that line and follow it until it gets essentially at where 2 is. Then record that value which in this case about 1.5

The limit of the function as x approaches 2 is 3.

In mathematics, a limit is a value that a function 'approaches' as the input (or variable) 'approaches' some value. To find the limit using the given graph, we need to examine the behavior of the function as it approaches a particular value. In this case, we look for the value the function approaches as x approaches a specific number.

From the graph, we can see that as x approaches 2 from the left side, the y-values approach 3. Similarly, as x approaches 2 from the right side, the y-values also approach 3.

Therefore, the limit of the function as x approaches 2 is 3.

Answer:

The correct answer is 12.5.

Step-by-step explanation:

When looking at the x axis, you locate the 2. After 2 minutes, the point connects at (2,12.5). Therefore, the correct answer is 12.5.

Answer:

At t = 2 minutes, remaining quantity of the radioactive element is 12.5 mg.

Step-by-step explanation:

To get the answer of this question we will solve this further with the help of the equation [tex]A_{t}=A_{0}e^{-kt}[/tex]

where k = decay constant

t = time for decay

[tex]A_{0}[/tex] = Initial quantity taken

From the graph attached we can say that 50 mg of a radioactive element remained half in 1 minute.

So the equation becomes

[tex]50=25e^{-k(1)}[/tex]

Now we take natural log on both the sides of the equation

ln50 = ln[25.[tex]e^{-k}[/tex]

3.912 = ln25 + [tex]ln(e^{-k})[/tex]

3.912 = 3.219 + (-k)lne

3.912 - 3.219 = -k [since lne = 1]

0.693 = -k

k = -0.693

Now we will calculate the remaining quantity of the element after 2 minutes

[tex]A_{t}=50.e^{-(0.693)(2)}[/tex]

              = [tex]50.e^{-1.386}[/tex]

              = [tex]\frac{50}{e^{1.386}}[/tex]

              = [tex]\frac{50}{3.9988}[/tex]

              = 12.50 mg

Now we confirm this value from the graph.

At t = 2 minutes, remaining quantity of the radioactive element is 12.5 mg.
