The estimate of the integral by parts ∫₀³f(x)g'(x) = 62.1
What is integration?Integration is the process of reverse differentiation. It is the process of finding the anti-derivative of a function.
How to estimate the value of the integral?Since we have the integral [tex]\int\limits^3_0 {f(x)g'(x)} \, dx[/tex] and f(x) = x³. To evaluate the integral within the limits, we use integration by parts.
So, for any integral by parts
[tex]\int\limits^a_b {u(x)v'(x)} \, dx = [u(x)v(x)]^{a} _{b} - \int\limits^a_b {v(x)u'(x)} \, dx[/tex]
So, for the given integral [tex]\int\limits^3_0 {f(x)g'(x)} \, dx[/tex], we have that
[tex]\int\limits^3_0 {f(x)g'(x)} \, dx = [f(x)g(x)]^{3} _{0} - \int\limits^3_0 {g(x)f'(x)} \, dx[/tex]
So, we have that
[tex]\int\limits^3_0 {f(x)g'(x)} \, dx = [f(x)g(x)]^{3} _{0} - \int\limits^3_0 {g(x)f'(x)} \, dx\\= [f(x)g(x) - f(0)g(0)] - [{g(3)f'(3) - g(0)f'(0)}][/tex]
Now, we have that f(x) = x³. So,f'(x) = 3x².
So,
f(3) = 3³ = 27 and f'(3) = 3(3)² = 27.Also, form the table
g(0) = 2.3 and g(3) = 4.9Substituting these into the equation, we have that
[tex]\int\limits^3_0 {f(x)g'(x)} \, dx = [f(3)g(3) - f(0)g(0)] - [{g(3)f'(3) - g(0)f'(0)}]\\= [27 \times 4.9 - 0 \times 2.3] - [{4.9 \times 27 - 2.3\times 27}]\\= (132.3 - 0) - (132.3 - 62.1)\\= 132.3 - 132.3 + 62.1\\= 0 + 62.1\\= 62.1[/tex]
So, integral [tex]\int\limits^3_0 {f(x)g'(x)} \, dx = 62.1[/tex]

On solving the system of linear equations 3x + 3y = 45 and x + 2y = 24, the cost for each shirt is obtained as $6, and cost for each pair of pants is obtained as $9.
What is a linear equation?
A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.
Let the cost of shirts be x and the cost of pair of pants be y.
The number of shirts bought by person A = 3
The number of pair of pants bought by person B = 3
The total cost for person A = $45
The equation for person A is -
3x + 3y = 45....(1)
The number of shirts bought by person B = 1
The number of pair of pants bought by person B = 2
The total cost for person B = $24
The equation for person B is -
x + 2y = 24....(2)
Multiply equation (2) by 3 -
3(x + 2y) = 24 × 3
3x + 6y = 72....(3)
Subtraction equation (1) from equation (3) -
3x + 6y - (3x + 3y) = 72 - 45
3x + 6y - 3x - 3y = 27
3y = 27
y = 9
Substitute the value of y in equation (2) -
x + 2(9) = 24
x + 18 = 24
x = 24 - 18
x = 6
Therefore, the cost of shirts and pants is x = 6 and y = 9 respectively.

An equation that represents the linear function shown in the table or mapping diagram is y = -x/4 - 3.
How to write an equation that represents the linear function?In order to write an equation that represents the linear function, we would use the point-slope form. Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:
y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
Where:
m represents the slope.x and y are the points.Next, we would determine the linear function representing the line which passes through the data points (-4, 6) and (8, 3) by using the point-slope form as follows:
y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
y - 6 = (3 - 6)/(8 - (-4))(x - (-4))
y - 6 = (3 - 6)/(8 + 4)(x + 4)
y - 6 = -3/12(x + 4)

What is divisibility?the capacity of being divided. Math. the capacity of being evenly divided, without remainder.
Divisibility rules or Divisibility tests have been mentioned to make the division procedure easier and quicker. If students learn the division rules in Math's or the divisibility tests for 1 to 20, they can solve the problems in a better way. For example, divisibility rules for 13 help us to know which numbers are completely divided by 13. Some numbers like 2, 3, 4, 5 have rules which can be understood easily. But rules for 7, 11, 13, are a little complex and need to be understood in-depth.
Divisibility rule for 10 states that any number whose last digit is 0, is divisible by 10.
Example: 10, 20, 30, 1000, 5000, 60000, etc.
For any given number, to check if it is divisible by 13, we have to add four times of the last digit of the number to the remaining number and repeat the process until you get a two-digit number. Now check if that two-digit number is divisible by 13 or not. If it is divisible, then the given number is divisible by 13.
For example: 2795 → 279 + (5 x 4)
→ 279 + (20)
→ 299
→ 29 + (9 x 4)

4. Find a value of x that is a solution to 5(x – 3) = x + 13. Describe how you found the solution. (3 points)
Answer:
see below
Step-by-step explanation:
Step 1
5(x – 3) = x + 13
Step 2
See if x is a solution
5 (6-3) ?= 6+13
5 (3) ?= 19
15 ?= 19
Step 3
This is not true so it is not a solution
Step 4
5(x – 3) = x + 13
Distribute
5x-15 = x+3
Subtract x from each side
5x-x -15 = x+13-x
4x-15 = 13
Add 15 to each side
4x-13+13 = 15+13
4x =28
Divide each side by 4
4x/4 = 28/4
x = 7
7 is a solution
Answer:
First you substitute 6 for x!
5(6 - 3) = 6 + 13
6 - 3 = 3
The equation is now:
5 * 3 = 6 + 13
5 * 3 = 15
6 + 13 = 19
The result is:
15 = 19 which is not a true statement.
x is not equal to 6.
Now lets try 7.
5(7 - 3) = 7 + 13
7 - 3 = 4

R(0) = 32. R(30) = 65.47.How to find the numeric value of a function or of an expression?To find the numeric value of a function or of an expression, we replace each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.
The function for this problem is defined as follows:
R(t) = 328 - 296e^(-0.004t)
At t = 0, the numeric value is found replacing the lone instance of t by zero, hence:
R(0) = 328 - 296e^(-0.004(0))
R(0) = 32.
At t = 30, the numeric value is found replacing the lone instance of t by 30, hence:
R(30) = 328 - 296e^(-0.004(30))

�
cscA in simplest radical form using a rational denominator.
The exact value of csc(A) is csc(A) = 7/20[√10]
How to determine the value of csc(A)From the question, we have the following parameters that can be used in our computation:
sec(A) = 7/3
Take the inverse of both sides
cos(A) = 3/7
Using the following trigonometry identity, we have
sin²(A) + cos²(A) = 1
Substitute the known values in the above equation, so, we have the following representation
sin²(A) + (3/7)² = 1
So, we have
sin²(A) = 40/49
Take the square roots
sin(A) = ±√(40/49)
The angle is in quadrant II
So, we have
sin(A) = √(40/49)
Take the inverse
csc(A) = √(49/40)
So, we have
csc(A) = 7√(1/40)
This gives
csc(A) = 7/[2√10]
Rationalize
csc(A) = 7/20[√10]

f(x) = 3x and g(x)=x-2, find f(g(4))
If f(x) = 3x and g(x)=x-2, then the value of f(g(4)) is 6.
What is a function?
A function is a mathematical object that assigns exactly one output to each input of a specified type. In other words, a function is a rule that takes in certain inputs (or "arguments") and produces a unique output. The inputs to a function are called the domain, while the set of possible outputs is called the range.
The given functions are f(x) = 3x and g(x)=x-2.
To find f(g(4)), we first need to evaluate g(4). The function g is defined as g(x) = x - 2, so g(4) = 4 - 2 = 2.
Next, we need to evaluate f(2), where f is defined as f(x) = 3x. So, f(2) = 3 * 2 = 6.
Therefore, f(g(4)) = f(2) = 6.
Hence, if f(x) = 3x and g(x)=x-2, then the value of f(g(4)) is 6.

Need help with question attached below in an image.
We can apply the order of four transformations to the graph of f(x) in order to sketch the graph of g(x): A 3-unit horizontal shift to the left : The graph becomes f(x-3 ) as a result, with a vertical asymptote at x = 0 rather than x = 3.
A ( -2 ) stretch in the vertical direction: The graph is now -2f(x-3), with a slope of -2 for x greater than 3 and 2 for x less than 3.An observation regarding the x-axis: The graph is now -2|f(x-3)|, which is the x-axis-reflecting graph of f(x-3) as a result of this change.A shift up one unit in the vertical: The result of this transformation is the final graph of g(x) = -2|x-3|+1, which is -2|f(x-3)|+1.2. To move from f(x) to g(x), four transformations are used:
A three-unit horizontal shift to the left: The graph thus shifts by a factor of -2 three units in the direction of the left A vertical stretch.
How does one plot a graph?You must first define the function and its domain before you can plot its graph. We can begin by sketching the piecewise linear graph of f(x) = |x|, which has a slope of 1 for x greater than 0 and -1 for x less than 0 in order to sketch the graph of g(x) = -2|x-3|+1. The vertical asymptote is shown by the x axis. For all real numbers, the definition of the f(x) graph exists.
