Domain: x ≥ 1/4
Calculating the composite functions and their domainsGiven that
f(x) = 1/(5x² + 3)
g(x) = √(4x - 1)
For the first pair, we have
(f . g)(x) = f(x) * g(x)
So, we have
(f . g)(x) = 1/(5x² + 3) * √(4x - 1)
Evaluate
(f . g)(x) = √(4x - 1)/(5x² + 3)
For the domain, we have
4x - 1 ≥ 0
x ≥ 1/4
Next, we have
(f . g)(x) = f(x) * g(x)
So, we have
(f + g)(x) = 1/(5x² + 3) + √(4x - 1)
Evaluate
[tex](f + g)(x) = \frac{5x^2\sqrt{4x-1}+3\sqrt{4x-1}+1}{5x^2+3}[/tex]
For the domain, we have
4x - 1 ≥ 0

Given the relation {(−3,−1),(x,0),(5,4),(6,13)} , which value for x would make the relation NOT a function?
Three man can do piece of work in 10 days. After three days one men left the work . And again after three days another man left then in how many days the remaining person will take to finish the work?
The remaining person will take 4 days to finish the work.
What is work?Work has a completely different connotation in science than it does in ordinary life. Every time labour is performed, energy is transmitted, as shown by the definition of work in physics.
Let's assume that each man can do the whole job in "x" days.
According to the problem, three men can do the job in 10 days, so their combined work rate is:
3/x = 1/10
Solving for x, we get x = 30.
This means that one man can do the job in 30 days.
After three days, one man leaves, so only two men are left to complete the remaining job. They have already worked for 3 days, so the remaining work is:
(2/3) * (7/10) = 14/30
This means that two men can do the remaining work in 14 days.
After another three days, one more man leaves, so only one man is left to complete the remaining job. They have already worked for a total of 6 days (3 days + 3 days), so the remaining work is:
(1/3) * (4/10) = 4/30
This means that one man can do the remaining work in 4 days.
Therefore, the remaining person will take 4 days to finish the work.

A line passes through point −9, 7 and has a slope of −43.
Write an equation in =+AxByC form for this line.
Use integers for A, B, and C.
A line passes through point −9, 7 and has a slope of −43, the equation of the line in the =+AxByC form is 43x + y = -380.
To write the equation of a line in the form of Ax + By = C, we need to find values for A, B, and C.
We know that the line passes through the point (-9, 7) and has a slope of -43. We can use the point-slope form of the equation to find the equation of the line:
y - y1 = m(x - x1)
Where m is the slope and (x1, y1) is a point on the line.
Substituting the values we know:
y - 7 = -43(x + 9)
Expanding and rearranging:
y - 7 = -43x - 387
43x + y = -380
Thus, the equation of the line in the =+AxByC form is 43x + y = -380.

Step-by-step explanation:
A town of 500,000 people is struck by a devastating epidemic. The number of people infected after t days is modeled by
500,000/1+499e^-1.617t
How many people will be infected 4 days after the breakout? Round to the nearest whole number.
Answer: The following formula determines the total number of infected people after t days:
500,000 / (1 + 499e^(-1.617t))
We can enter t = 4 into the algorithm to determine the total number of affected 4 days after the outbreak and then assess:
Step-by-step explanation:
500,000 / (1 + 499e^(-1.617(4))) = 500,000 / (1 + 499e^(-6.468))
= 500,000 / (1 + 499(0.00155))
= 500,000 / (1 + 0.77445)
= 500,000 / 1.77445
When this is rounded to the closest whole number, we obtain:
281,580
Therefore, four days after the outbreak, about 281,580 people will be infected.
What lump sum should be deposited in an account that will earn 9% compounded every 2 months, to grow to $100,000 in 32 years? Show your step process, when you are solving the problem.
Answer:
We should deposit approximately $14,408.92 in the account to grow to $100,000 in 32 years, assuming a 9% annual interest rate compounded every 2 months.
Step-by-step explanation:
To solve this problem, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
where:
A = the future value of the investment
P = the initial principal (the lump sum we need to deposit)
r = the annual interest rate (9% in this case)
n = the number of times the interest is compounded per year (since interest is compounded every 2 months, or 6 times per year, n = 6)
t = the number of years (32 years in this case)
We are given that we want the investment to grow to $100,000 in 32 years, so we can set A = $100,000 and solve for P:
$100,000 = P(1 + 0.09/6)^(6*32)
Simplifying the expression inside the parentheses:
$100,000 = P(1.015)^192
Dividing both sides by (1.015)^192:
P = $100,000 / (1.015)^192
Using a calculator:
P ≈ $14,408.92
Therefore, we should deposit approximately $14,408.92 in the account to grow to $100,000 in 32 years, assuming a 9% annual interest rate compounded every 2 months.

The critical t value for a confidence level of 80% with a sample size of 11 is 1.833.
What is value?
Value in math is the numerical representation of a concept or quantity. It can be used to measure, compare, or describe a range of concepts, including distance, speed, time, money, and more. Value is an essential part of mathematics, as it allows for the comparison of different numbers and is used in equations and formulas to solve problems. Value is also used to represent specific ideas, such as the value of pi or the value of "infinity".
The critical t value represents the boundary between the middle two categories of a t-distribution with a confidence level of 80%. To calculate this value, we must first calculate the degrees of freedom (DF) which is equal to the sample size minus 1. In this case, the DF is 10.
Next, we must use a t-table to find the t value. Using the chart, we can see that for a confidence level of 80%, the t value is 1.833. This means that any value of t that is higher than 1.833 will fall within the highest category of the t-distribution and is considered statistically significant. Therefore, the critical t value for a confidence level of 80% with a sample size of 11 is 1.833.

Given f(x)= what is the
value of f(12)?
The value of f(12) for the function f(x) = (x - 4)/16 is 0.5.
Here we have been given the function
f(x) = (x - 4)/16
This function models the expression (x - 4)/16. This implies that we will get a different value of f(x) for every different value of x.
Now here we have been given to find the value of f(12). This implies that we need to find the value of f(x) = (x - 4)/16 when the value of x is 12.
Hence, to find f(12) we need to replace x with 1 in the function. This will give us
(12 - 4)/16
= 8/16
= 0.5
Therefore, f(12) is 0.5

The United States Senate Committee on Commerce, Science, and Transportation consists of 23 members, 12 Republicans and 11 Democrats. The Surface Transportation and Merchant Marine Subcommittee consists of 8 Republicans and 7 Democrats. How many ways can members of the Subcommittee be chosen from the Committee?
The number of ways members of the Subcommittee can be chosen from the Committee is 12,077,462,720.
What is number?Number is a mathematical object used to count, measure, and label. It is a concept used in math, science, and everyday life. Number has been around since the dawn of time and is an integral part of the universe. Numbers can be used to identify objects, measure quantities, and understand relationships between things. They are also used to represent abstract concepts, such as money, time, and space. Numbers can be used to solve problems and make decisions.
The number of ways members of the Subcommittee can be chosen from the Committee is equal to the number of combinations of 8 Republicans and 7 Democrats out of the total 23 members. This can be calculated using the combination formula, which is:
C(23, 8) x C(15, 7) = 12,077,462,720
The combination formula is defined as C(n,r) = n!/(r!(n-r)!), where n is the total number of members in the Committee (23) and r is the number of Republicans and Democrats from the Subcommittee (8 and 7, respectively). In this case, the n! term is equal to 23!, which is 8,314,814,080, and the r! term is equal to 8! x 7!, which is 40,320. Therefore, 12,077,462,720 is the total number of ways members of the Subcommittee can be chosen from the Committee.
This number can also be interpreted as the number of possible permutations of the 8 Republicans and 7 Democrats within the Subcommittee. This means that there are 12,077,462,720 ways to assign the 8 Republicans and 7 Democrats to the Subcommittee, without changing the number of Republicans and Democrats in the Subcommittee.
In conclusion, the number of ways members of the Subcommittee can be chosen from the Committee is 12,077,462,720. This number can be calculated using the combination formula, and it represents the number of possible permutations of the 8 Republicans and 7 Democrats within the Subcommittee.

ABCDEF form a regular hexagon with centre O.−−→OA=10a−−→OB=10bX is the midpoint of BC. Y is the point on AB extended such that AB : BY = 3 : 2. Express: (i) the vector −−→EX in terms of a and/or b. (ii) the vector −−→XY in terms of a and/or b.
Results:
(i) The vector −→EX in terms of a and/or b, →X = 1/2 (10b →OB + 10a →OA)
(ii) The vector −−→XY in terms of a and/or b→XY = →Y - 1/2 (10b →OB + 10a →OA)
How to express the vector?(i) We can use the midpoint formula, which states that the midpoint of a line segment is the average of the coordinates of its endpoints to express the vector −→EX in terms of a and/or b.
Since X is the midpoint of BC, we can express X as the average of the coordinates of B and C:
→X = 1/2 (→B + →C)
Since B is located at 10b units in the direction of vector →OB from O, and C is located at 10a units in the direction of vector →OA from O, we can express →B and →C in terms of a and b:
→B = 10b →OB
→C = 10a →OA
Substituting these values into the expression for →X, we get:
→X = 1/2 (10b →OB + 10a →OA)
(ii) To express the vector −→XY in terms of a and/or b, we can use the given ratio AB: BY = 3: 2.
Since AB is a vector from A to B, we can express it as →AB = →B - →A.
Substituting the expressions for →B and →A, we get:
→AB = 10b →OB - →OA
Since AB: BY = 3: 2, we can express BY as 2/3 of AB:
→BY = 2/3 (→AB)
Substituting the expression for →AB, we get:
→BY = 2/3 (10b →OB - →OA)
Finally, we can express →XY as the vector from Y to X, which is the opposite of →X to →Y:
→XY = →Y - →X
Substituting the expressions for →X and →Y, we get:
→XY = →Y - 1/2 (10b →OB + 10a →OA)

The table represents equivalent ratios. Which statements are true? (pick two please!)
The missing y-value is -4
The missing x-value is 2
The ordered pair (-1,2) is part of the ratio table.
The points will be in quadrants | and |||
The missing value of y is -4 and the ordered pair (-1,2) is part of the ratio table. thus, Options (A) and (C) are correct.
The fact that analogous ratios have the feature that the ratio of the corresponding words is constant must be used to determine whether claims are true. Let's utilize this property to add the values that are missing:
x y
-1 2
x 4 -> since (-1/2) = (x/4), we can solve for x: x = -2
1 -2
2 y -> since (2/(-2)) = (-1/2), we can solve for y: y = -4
Therefore, the missing x-value is -2, and the missing y-value is -4. Also, the ordered pair (-1,2) is part of the ratio table.
