Determine the domain and range
Step-by-step explanation:
To determine the domain and range of (g f) (x), we first need to find the composition of the functions f(x) and g(x):
(g f) (x) = g(f(x)) = g(2/(x^2-1)) = 2/(x^2-1) + 1
The domain of f(x) is all real numbers except x = -1 and x = 1, since these values would make the denominator equal to zero. Therefore, the domain of (g f) (x) is also all real numbers except x = -1 and x = 1.
To find the range of (g f) (x), we can start by finding the range of f(x). Since the denominator of f(x) is always positive (except at x = -1 and x = 1), the range of f(x) is all real numbers except 0.
When we add 1 to f(x), we shift the range of f(x) up by 1 unit. So, the range of (g f) (x) is all real numbers except 1.
Therefore, the domain of (g f) (x) is all real numbers except x = -1 and x = 1, and the range of (g f) (x) is all real numbers except 1.

The given piecewise function is not continuous.
What is a continuous function?Continuous function is a function such that a continuous variation of the argument induces a continuous variation of the value of the function.
Given is the piecewise function as -
f(x) = {(x² - 2x - 8)/(x + 2)} x ≠ -2
f(x) = {k} x = - 2
At {x} = - 2, the function is not defined and we get -
k = {(-2)² - 2(-2) - 8)/(- 2 + 2)} = {(-2)² - 2(-2) - 8)/0} = ∞
So, the function is not continuous.

A doctor orders a prescription that has a recommended dosage of 5 mg/lb every 12 hours. Our supply of the drug is a 0.9 g/mL solution. The patient is 72.7 kg. How many mL of the solution should we use for each dose?
The doctor should order a prescription of 0.8906 mL of the 0.9 g/mL solution for each dose.
What is the density?
Density is a physical property of matter that measures the amount of mass per unit volume. It is calculated by dividing the mass of an object or substance by its volume. The resulting number represents the amount of matter, or mass, that is present in a given volume.
The formula for density is:
Density = Mass / Volume
First, we need to convert the weight of the patient from kilograms to pounds, as the recommended dosage is in mg/lb:
72.7 kg x 2.205 lbs/kg = 160.305 lbs
The recommended dosage is 5 mg/lb, so for a 160.305 lbs patient, the total dosage per dose would be:
160.305 lbs x 5 mg/lb = 801.525 mg
Now we need to convert this dosage from mg to mL, using the concentration of the solution, which is 0.9 g/mL:
1 g = 1000 mg, so 0.9 g = 0.9 x 1000 = 900 mg
To convert mg to mL, we can use the density formula:
Density = Mass / Volume
Rearranging the formula to solve for volume, we get:
Volume = Mass / Density
So, the volume of solution needed for each dose would be:
Volume = 801.525 mg / 900 mg/mL
Volume = 0.8906 mL
Hence, the doctor should order a prescription of 0.8906 mL of the 0.9 g/mL solution for each dose.

C. sampling the first 50 batteries made each day and testing to see if they work
D. randomly sampling 50 batteries throughout the day and testing to see if they work
Correct option is D. randomly sampling 50 batteries throughout the day and testing to see if they work would provide the most valid results.
What is a sample?A sample is described as a smaller, more manageable representation of a larger group. a smaller population with characteristics of a larger one. A sample is used in statistical analysis when the population size is too large to include all participants or observations in the test.
The sample may be biased if it is taken from the first 25 batteries made each day (option A) or the last 25 batteries made each day (option B).
The first and final batteries made each day could not be an accurate representation of the total quality of the batteries produced that day if the battery manufacturing process is not consistent throughout the day.
Although battery quality can change during the day, sampling the first 50 batteries produced each day (option C) may also add bias into the sample.
The ideal course of action is to randomly select 50 batteries throughout the day (option D), since this helps to ensure that the sample is reflective of the general caliber of batteries manufactured that day.
Random sampling reduces the possibility of bias into the sample.
A more accurate image of the quality of the batteries manufactured can be obtained using this method, which is also more likely to capture any variations in battery quality over the day.
Therefore, option D would provide the most valid results.

A carpenter purchased 50 ft of redwood and 90 ft of pine for a total cost of $292. A second purchase, at the same prices, included 90 ft of redwood and 70 ft of pine for a total cost of
$406. Find the cost per foot of redwood and of pine.
redwood
dollars per foot
pine
dollars per foot
The cost per foot of redwood is $42.37, and the cost per foot of pine is $90.65.
What is an expression?In mathematics, expression is defined as the relationship of numbers, variables, and functions using mathematical signs such as addition, subtraction, multiplication, and division.
Let's use the variables r and p to represent the cost per foot of redwood and pine, respectively.
From the first purchase, we can set up the following system of equations:
50r + 90p = 292 (equation 1)
90r + 70p = 406 (equation 2)
To solve for r and p, we can use the method of substitution. Solving equation 1 for r, we get:
r = (292 - 90p) / 50
Substituting this expression for r into equation 2, we get:
90[(292 - 90p) / 50] + 70p = 406
Multiplying both sides by 50 to clear the fraction, we get:
162 - 27p + 70p = 4060
Combining like terms, we get:
43p = 3898
Dividing both sides by 43, we get:
p = 90.65
So the cost per foot of pine is $90.65.
To find the cost per foot of redwood, we can substitute this value of p into equation 1 and solve for r:
50r + 90(90.65) = 292
50r = 2118.5
r = 42.37
So the cost per foot of redwood is $42.37.
Therefore, the cost per foot of redwood is $42.37, and the cost per foot of pine is $90.65.

PRACTICE ANOTHER
Answer:
Step-by-step explanation:
(a) Since the current entering and leaving the intersection of wires must be equal, we have:
x + y = 18 (current entering the top intersection)
z + w = 18 (current leaving the top intersection)
x + z = 9 (current entering the bottom intersection)
y + w = 9 (current leaving the bottom intersection)
We can solve this system of equations using substitution or elimination. For example, we can eliminate w by adding the first two equations and subtracting the last two equations:
2x + 2y + 2z = 36
2y + 2z - 2x = 0
2z - 2x = 9
Solving for z in terms of x, we get:
z = (x + 9/2)
Substituting this into the first equation, we get:
x + y = 18
Substituting z in terms of x into the second equation, we get:
w = (18 - z) = (18 - x - 9/2) = (27/2 - x)
Therefore, the solution in terms of x, y, z, and w is:
(x, y, z, w) = (x, 18 - x, x + 9/2, 27/2 - x)
(b) To know all of the currents exactly, we need to measure the current in any one wire that is not already determined by the system of equations. From part (a), we see that w is determined in terms of x, y, and z. Therefore, we should measure the current in wire x or y to know all of the currents exactly.

Erik spends $680 for cable television service. The cable company offers a deal that promises Erik 3 free months of cable if he signs a contract with them for $40 per month.
Complete the equation below to find the number of months that Erik will have cable television service with this deal. Use m to represent the number of months.
Answer:
Step-by-step explanation:
The cable company offers Erik 3 free months of cable if he signs a contract with them for $40 per month. This means that Erik will pay for (m - 3) months of cable service, since he will get 3 months for free. So the cost of the cable service for (m - 3) months is:
Cost = $40 per month x (m - 3) months
Cost = $40m - $120
We know that Erik spent $680 for the cable television service. So we can set up an equation to relate the cost to the number of months:
$40m - $120 = $680
To solve for m, we can isolate the variable on one side of the equation:
$40m = $800
m = 20
Therefore, Erik will have cable television service for 20 months with this deal.
