Horizontal asymptote of c(x) is 450.
What is Horizontal asymptote?A horizontal asymptote is a line that guides the graph of a function for x-values but is not itself a part of the graph. "far," either "far" to the right or "far" to the left. Eventually, whether the graph is large enough or little, it may intersect.
According to the information:Since we have given that
Cost to produce one refrigerator = $450
Fixed monthly cost = $200,000
Thus, the following formula represents the average cost to produce x refrigerators:
C(x) = (200000 + 450x)/x
Horizontal asymptote of c(x) would be
= 450x/x
= 450
Hence, Horizontal asymptote of c(x) is 450

A triangle has side lengths of (2b + 5c) centimeters, (10b + 7d) centimeters, and
(4d-3c) centimeters. Which expression represents the perimeter, in centimeters,
of the triangle?
The perimeter of the triangle can be express as follows:
12b + 11d + 2c
How to find perimeter of a triangle?The perimeter of a figure is the sum of the whole sides of the figure.
A triangle has three sides. Therefore, the perimeter of a triangle is the sum of the three sides.
Therefore, the sides of the triangle are of lengths (2b + 5c) centimetres, (10b + 7d) centimetres, and (4d-3c) centimetres.
Hence, the perimeter of the triangle can be represented as follows:
Perimeter of the triangle = 2b + 5c + 10b + 7d + 4d - 3c
Perimeter of the triangle = 2b + 10b + 7d + 4d + 5c - 3c
Perimeter of the triangle = 12b + 11d + 2c
Therefore, the perimeter of the triangle can be express as follows:
12b + 11d + 2c

Answer:
the triangle is a right angle triangle. I can't see the correct explanation here so I will explain
Step-by-step explanation:
to work out whether triangles are right angle you do :
square root of (5² + 12²) so it would be 25 + 144 =169 and the square root of 169 is 13 . we do this because the square root of both of the side lengths squares should make ths longer side in this case it makes 13 so it is a right angled triangled

A coin is flipped 15 times where each flip comes up either heads or tails. How many possible outcomes (a) contain exactly four tails (b) contain at least three heads?
Using the arrangements formula, it is found that:
a) There are 1365 possible outcomes that contain exactly four tails.
b) There are 1,307,674,399,889 possible outcomes that contain at least three heads.
What is the arrangements formula?The number of possible arrangements of n elements is given by the factorial of n, that is:
[tex]A_n = n![/tex]
When there are repetitions, the number of ways is given as follows:
[tex]A_{n}^{n_1, n_2, \cdots, n_n} = \frac{n!}{n_1!n_2! \cdots n_n!}[/tex]
In which [tex]n_1, n_2, \cdots, n_n[/tex] are the numbers of repetitions.
Item a:
11 heads and 4 tails, hence:
[tex]A_{15}^{11,4} = \frac{15!}{11!4!} = 1365[/tex]
There are 1365 possible outcomes that contain exactly four tails.
Item b:
The total number is:
[tex]A_{15} = 15! = 1,307,674,400,000[/tex]
With no heads:
[tex]A_{15}^{15,0} = \frac{15!}{15!0!} = 1[/tex]
With one head:
[tex]A_{15}^{14,1} = \frac{15!}{14!1!} = 15[/tex]
With two heads:
[tex]A_{15}^{13,2} = \frac{15!}{13!2!} = 95[/tex]
Hence the number of outcomes with less than three heads is:
1 + 15 + 95 = 111
With at least three heads, the number of outcomes is:
[tex]1,307,674,400,000 - 111 = 1,307,674,399,889[/tex]
There are 1,307,674,399,889 possible outcomes that contain at least three heads.

For Ann and Tom to have $20,000 at the end of 10 years, they must deposit a sum of $6,131.14.
What is the principal?
To calculate the sum of money they must deposit, use the compound interest formula.
From the compound interest formula;
P = A / ( 1 + r/n )^(nt)
Given that;
Final amount A = 20,000Interest rate r = 12% = 12/100 = 0.12Compound n = quarterly = 4Time t = 10 yearsPrincipal P = ?P = A / ( 1 + r/n )^(nt)
P = 20,000 / ( 1 + 0.12/4 )^(4×10)
P = 20,000 / ( 1.03)^40
P = 20,000 / 3.26203779

If they work together, they need 15/8 hours to assemble one shelving unit.
What does work mean in math?
In summary, work is done when a force acts upon an object to cause a displacement. Three quantities must be known in order to calculate the amount of work. Those three quantities are force, displacement and the angle between the force and the displacement.According to tittle, we know worker A can assemble a shelving unit in 5 hours , which means worker A can finish 1/5 of work in 1 hour . And worker B can finish 1/3 of work in 1 hour.
If A & B work together , they will spend the same time t to assemble only one shelving .
That means, 1/5t + 1/3 t = 1 (equation)
1/5 t is worker A's workload during time t , 1/3 t is worker B workload.
So, 1/5 t + 1/3t = 1 is the answer
⇒ 5t + 3t = 15
⇒ t = 15/8 hours

Answer:
You did not list any choices but if you simplify that the answer is 6√2x-3√2
Step-by-step explanation:
If they want you to factor it instead of simplifying the answer is 3√2(2x-1)
Answer:
[tex]6x\sqrt{2} - 3\sqrt{2}[/tex]
Step-by-step explanation:
So you haven't provided any options, but I'm assuming they want it in most simplified form.
To do this, we simply combine like terms, and in this case you can see the [tex]\sqrt{2}[/tex] as a variable, if it makes it easier to think about why we can combine terms. So just like how we can do: [tex]2y + y = 3y[/tex] we can do the same thing here, since sqrt(2) constant and it's in each expression.
So if it makes a bit easier to represent, I'll rewrite the equation such that sqrt(2) = y
[tex]5xy-3y+xy[/tex]
So in here, think of y as the variable and the 5x, -3, and x as the coefficients.
In doing this we can combine the terms by adding them, since they all have the same "variable" (sqrt(2))
[tex](5x-3+x)y[/tex]
Simplify this expression to get
[tex](6x-3)y[/tex]
Now just plug the sqrt(2) back in as y and you get the expression
[tex](6x-3)\sqrt{2}[/tex]
Since we can't combine the 6x and -3 in any way, we we can just distribute this back into the sqrt(2)
[tex]6x\sqrt{2} - 3\sqrt{2}[/tex]

What is the probability of spending between 3.2 and 4.2 days in recovery? f. The 90th percentile for recovery times is days.
Using the normal distribution, we have that the desired information is given as follows:
a) X ~ N(3,1.8).
b) 3 days.
c) Z = 0.5556.
d) 0.33 = 33%.
e) 0.2048 = 20.48%.
f) 5.3 days.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The mean and the standard deviation are given, respectively, by:
[tex]\mu = 3, \sigma = 1.8[/tex]
Hence the distribution is X ~ N(3,1.8), and, as is standard in the normal distribution, the median is the same as the mean, which is of 3 days.
The Z-score for a patient that took 4 days to recover is Z when X = 4, hence:
Z = (4 - 3)/1.8 = 0.5556.
The probability of spending more than 3.8 days in recovery is one subtracted by the p-value of Z when X = 3.8, hence:
Z = (3.8 - 3)/1.8 = 0.44.
Z = 0.44 has a p-value of 0.67.
1 - 0.67 = 0.33.
The probability is of 0.33 = 33%.
The probability of spending between 3.2 and 4.2 days in recovery is the p-value of Z when X = 4.2 subtracted by the p-value of Z when X = 3.2, hence:
X = 4.2:
Z = (4.2 - 3)/1.8
Z = 0.67.
Z = 0.67 has a p-value of 0.7486.
X = 3.2:
Z = (3.2 - 3)/1.8
Z = 0.11.
Z = 0.11 has a p-value of 0.5438.
0.7486 - 0.5438 = 0.2048 = 20.48%.
The 90th percentile is X when Z = 1.28, hence:
1.28 = (X - 3)/1.8
X - 3 = 1.8 x 1.28
X = 5.3 days.
