Answer:
\(Total = \$7800\)
Step-by-step explanation:
Given
\(Cost = \$32.50\) per square yard
\(Length = 432.0ft\)
\(Width = 5.0ft\)
Required
Determine the cost of carpet and installation
First, calculate the area of the carpet
\(Area = Length * Width\)
\(Area = 432.0ft * 5.0ft\)
\(Area = 2160ft^2\)
Convert to square yard
\(Area = \frac{2160yd^2}{9}\)
\(Area = 240yd^2\)
The cost is then calculated as:
\(Total= Area * Unit\ Cost\)
\(Total = 240 * \$32.50\)
\(Total = \$7800\)

Answer:
we conclude that:
\(\frac{2^{-\frac{4}{3}}}{54^{-\frac{4}{3}}}=81\)
Step-by-step explanation:
Given the expression
\(\frac{2^{-\frac{4}{3}}}{54^{-\frac{4}{3}}}\)
\(\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}\:=\:x^{a-b}\)
\(\frac{2^{-\frac{4}{3}}}{54^{-\frac{4}{3}}}=\left(\frac{2}{54}\right)^{-\frac{4}{3}}\)
\(\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}\)
\(=\frac{1}{\left(\frac{2}{54}\right)^{\frac{4}{3}}}\)
\(=\left(\frac{1}{27}\right)^{-\frac{4}{3}}\)
\(\mathrm{Apply\:exponent\:rule}:\quad \left(\frac{a}{b}\right)^c=\frac{a^c}{b^c}\)
\(=\frac{1}{\frac{1^{\frac{4}{3}}}{27^{\frac{4}{3}}}}\)
\(=\frac{1}{\frac{1^{\frac{4}{3}}}{81}}\) ∵ \(27^{\frac{4}{3}}=81\)
\(\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{1}{\frac{b}{c}}=\frac{c}{b}\)
\(=\frac{81}{1^{\frac{1}{3}}}\)
\(\mathrm{Apply\:rule}\:1^a=1\)
\(=\frac{81}{1}\)
\(=81\)
Therefore, we conclude that:
\(\frac{2^{-\frac{4}{3}}}{54^{-\frac{4}{3}}}=81\)

Answer:
Lower quartile = 6
Median = 8
Upper quartile = 9
Step-by-step explanation:
If you take away a number from each end of the number set one by one, you will end up with 7 and 9 in the middle. To find the median between two numbers, add them together then divide them by 2.
7 + 9 = 16
16 ÷ 2 = 8
_________________
To find the lower and upper quartiles, split the number set into two where the median is, then, find the median of those two sections.
Lower quartile: 4, 5, 6, 6, 7
Median = 6
-
Upper quartile: 9, 9, 9, 9, 9
Median = 9
So, the median of the whole set is 8, the lower quartile is 6, and the upper quartile is 9.

In 7 days, Lin's sister will be paid $75 and will deposit it into her checking account. If there are no other transactions besides this deposit and the daily fee, will Lin continue to be charged $7.95 each day after this deposit is made? What will be her balance at that time?
Lin won't to be charged $7.95 each day after the deposit is made.
Why do banks impose fees on small balances?Financial organizations require minimum balances simply because their clients are an expense. To manage branches, keep accounts up to date, provide customer care, and other things, your bank or credit union must pay overhead.
If you maintain a certain balance in your account or adhere to additional conditions, like connecting your checking and savings accounts, banks frequently forgo their charge. Some banks could have a minimum balance requirement and impose fees if you go below it.
Lin's account balance is much above zero (0), so she won't be charged $7.95 each day. However, if her account balance were to drop below zero, she would be charged for any additional daily deposits made.
No Lin won't be charged.

Step-by-step explanation:
Shaded Area = area of the larger circle - area of the smaller circle
Area of the larger circle = πr²
Where,
r = 6.5 cm
Area = π*6.5² = 42.25π cm²
Area of smaller circle = πr²
Where,
r = 2.3 cm
Area = π*2.3² = 5.29π cm²
✔️Shaded area = 42.25π - 5.29π = 36.96π = 116.113264
Area = 116 cm² (3 S.F)

Option C is correct.
∫\(\frac{x+2019}{x^{2}+9 }\)
Split up the integral:
\(\displaystyle\int\frac{x+2019}{x^2+9}\,\mathrm dx = \int\frac{x}{x^2+9}\,\mathrm dx + \int\frac{2019}{x^2+9}\,\mathrm dx\)
For the first integral, substitute y = x ² + 9 and dy = 2x dx. For the second integral, take x = 3 tan(z) and dx = 3 sec²(z) dz. Then you get
\(\displaystyle \int\frac x{x^2+9}\,\mathrm dx = \frac12\int{2x}{x^2+9}\,\mathrm dx \\\\ = \frac12\int\frac{\mathrm du}u \\\\ = \frac12\ln|u| + C \\\\ =\frac12\ln\left(x^2+9\right)\)
and
\(\displaystyle \int\frac{2019}{x^2+9}\,\mathrm dx = 2019\int\frac{3\sec^2(z)}{(3\tan(z))^2+9}\,\mathrm dz \\\\ = 2019\int\frac{3\sec^2(z)}{9\tan^2(z)+9}\,\mathrm dz \\\\ = 673\int\frac{\sec^2(z)}{\tan^2(z)+1}\,\mathrm dz \\\\ = 673\int\frac{\sec^2(z)}{\sec^2(z)}\,\mathrm dz \\\\ = 673\int\mathrm dz \\\\ = 673z+C \\\\ = 673\arctan\left(\frac x3\right)+C\)
Then

In Exploration 5.4.2 Question 2, what conclusion can you make about the value of the derivative at
the maximum or minimum for a continuous function?
The value of the derivative at the maximum or minimum for a continuous function must be zero.
What happens with the derivative at the maximum of minimum?So, remember that the derivative at a given value gives the slope of a tangent line to the curve at that point.
Now, also remember that maximums or minimums are points where the behavior of the curve changes (it stops going up and starts going down or things like that).
If you draw the tangent line to these points, you will see that you end with horizontal lines. And the slope of a horizontal line is zero.
So we conclude that the value of the derivative at the maximum or minimum for a continuous function must be zero.

Loudness, pitch, and timbre are the three psychological aspects of sound that are influenced by the physical properties of sound waves.
What is a sound wave?When energy moves through a medium (such as air, water, or any other liquid or solid matter), it creates a pattern of disturbance known as a sound wave that propagates away from the sound source.
When an object vibrates, sound waves are produced that are similar to pressure waves, like when a phone rings.
Pitch, intensity, and timbre are three key components of the field of sound psychology or psychoacoustics. People can distinguish the harmonics of a complex periodic sound wave under certain conditions thanks to the way that humans perceive sound and music.
Thus, loudness, pitch, and timbre are the three psychological aspects of sound that are influenced by the physical properties of sound waves.

2) Why is it that when you fill the venn diagram with the number of elements, you
always need to start from the intersection of all sets?
Answer:
This is because it is easier this way.
You avoid the problem of putting an element in one set and then realizing that the element also belongs to another set, then you must erase something in order to put the element in both sets. Starting with the intersection allows you to know where will be each set in the diagram, and in this way, the diagram should end up being more readable or "clean".
This may seem small, but being "clean" when doing math, will allow you to have an easier time dealing with a lot of problems. And also will be easier for other people when reading your equations and such.
How many 11-card hands are possible with a 20-card deck?
There is only 1 possible 11-card hand that can be formed from a 20-card deck.
To determine the number of 11-card hands possible with a 20-card deck, we can use the concept of combinations.
The number of combinations, denoted as "nCk," represents the number of ways to choose k items from a set of n items without regard to the order. In this case, we want to find the number of 11-card hands from a 20-card deck.
The formula for combinations is:
nCk = n! / (k!(n-k)!)
Where "!" denotes the factorial of a number.
Substituting the values into the formula:
20C11 = 20! / (11!(20-11)!)
Simplifying further:
20C11 = 20! / (11! * 9!)
Now, let's calculate the factorial values:
20! = 20 * 19 * 18 * ... * 2 * 1
11! = 11 * 10 * 9 * ... * 2 * 1
9! = 9 * 8 * 7 * ... * 2 * 1
By canceling out common terms in the numerator and denominator, we get:
20C11 = (20 * 19 * 18 * ... * 12) / (11 * 10 * 9 * ... * 2 * 1)
Performing the multiplication:
20C11 = 39,916,800 / 39,916,800
Finally, the result simplifies to:
20C11 = 1
Consequently, with a 20-card deck, there is only one potential 11-card hand.

The Future value of an annuity due of $200 each quarter for 2 1 2 years at 13%, compounded quarterly is $10263.734 ..
The future value of an annuity is the value of a group of regular payments at some point in the future. It assumes a particular rate of return, or discount rate. The higher the discount rate, the greater the annuity's future value.
P = PMT× ((1+r)ⁿ −1)/r
where:
P---> Future value of an annuity stream
PMT---->Dollar amount of each annuity payment
r -->Interest rate (also known as discount rate)
n--->Number of periods in which payments will be
We have given that
Present value for an Annuity = $200
compounded rate , r = 13%
but compounded quarterly, then, r = 13%/4

Number of years , n = 2 + 1/2 = 5/2
then change into quarterly, n = 5/2 × 4 = 10
Future value formula ,
F.V = PMT ( (1+i)ⁿ - 1)/r

The diameter or the width of the running track is 17 meters rounded to the nearest integer.
What is the perimeter of a rectangle and a circle?The perimeter of a rectangle is 2(l + w) and the circumference of a circle is 2πr.
Given, the running track consists of two straight paths each measuring 84 meters in length, and two semicircles with a diameter(d), hence radius is (d/2) = r in meters.
Also given that the distance around the track is 400 meters.
∴ The total perimeter of the running track is the sum of the perimeter of the rectangle and the circumference of two semicircles which results in a circle and the diameter and the width is the same seems obvious from the diagram itself, therefore d = w and r = w/2.
∴ 84 + πr² + 84 + πr² = 400.
2πr² = 232.
πr² = 216.
r² = 68.8.
