If ,f(x)=1/4x+3 what is the equation for f–1(x)?
f–1(x) = 4x - 3
f–1(x) = 4(x - 3)
f–1(x) = 4(x + 3)
f–1(x) = 4x + 3
Answer:
\(f {}^{ - 1} (x) = 4(x + 3)\)
Step-by-step explanation:
We would like to find the inverse of the following function .
\(\longrightarrow f(x) = \dfrac{1}{4}x +3 \)
Step 1 : Replace \(f(x) \) with \(y \) . We have
\(\longrightarrow y =\dfrac{1}{4}x +3 \)
Step 2 : Interchange x and y :-
\(\longrightarrow x = \dfrac{1}{4}y + 3 \)
Step 3 : Solve for y :-
\(\longrightarrow x - 3 =\dfrac{1}{4}y \)
Multiply both sides by 4,
\(\longrightarrow 4(x-3) = y \)
Step 4 : Replace y with f-¹(x) :-
\(\longrightarrow 4(x -3)=f^{-1}(x) \)
Interchange the sides ,
\(\longrightarrow \underline{\underline{ f^{-1}(x)= 4(x-3)}}{}\)

Question 3 A 44-metres long fire-fighting ladder is leaned against a building, as shown in the diagram. The base of the ladder is 7 metres from the building and 3 metres above the ground. How high on the building will the ladder reach?
The ladder will reach a Height of approximately 43.46 meters on the building.
To find out how high on the building the ladder will reach, we can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
In this case, the ladder forms a right triangle with the ground and the building. The base of the ladder is 7 meters, the height of the building is what we need to find, and the length of the ladder is given as 44 meters.
Using the Pythagorean theorem, we can set up the equation:
(Height of the building)^2 + 7^2 = 44^2
Simplifying the equation, we have:
(Height of the building)^2 + 49 = 1936
Subtracting 49 from both sides, we get:
(Height of the building)^2 = 1887
To find the height of the building, we take the square root of both sides:
Height of the building = √1887
Calculating the square root of 1887, we find that the height of the building is approximately 43.46 meters.
Therefore, the ladder will reach a height of approximately 43.46 meters on the building.

salesperson earns $345 for selling $2300 in merchendice find the commison rate
Answer:
The commission rate is 15%
Step-by-step explanation:
commission = commission rate x sales
where the commission rate is expressed as a decimal.
In this case, the salesperson earned a commission of $345 for selling $2,300 in merchandise. Therefore, we have:
345 = commission rate x 2300
To solve for the commission rate, we can divide both sides by 2300:
commission rate = 345/2300
Simplifying this expression, we get:
commission rate = 0.15
So, the commission rate is 15%

The height of a rectangular box is 4ft. The length is 2 ft longer than thrice the width x . The volume is 480^3
what's the length and the width
SOLUTION
From the question
\(\begin{gathered} \text{height of the box h = 4ft} \\ \text{width = x} \\ \text{length = 2 + 3x} \\ \text{Volume = 224ft}^3 \end{gathered}\)Since the length is 2ft longer than trice the width, the length = 2 + 3x, since the width is given as x.

sequence three missing terms to comple 7444> →→19-
To complete the sequence "7444> →→19-", we need to find the missing terms that fit the pattern established by the given numbers. Let's analyze the sequence and identify any discernible pattern or rule.
Looking at the sequence, we can observe that each number is decreasing by a certain value. In this case, the first number is 7444, and the second number is 19, indicating a decrease of 7425. Now, we need to continue this pattern.
To find the third missing term, we subtract 7425 from 19, resulting in -7406. Therefore, the third missing term is -7406
To find the fourth missing term, we subtract 7425 from -7406, resulting in -14831. Therefore, the fourth missing term is -14831.
To find the fifth missing term, we subtract 7425 from -14831, resulting in -22256. Therefore, the fifth missing term is -22256.
Therefore, the completed sequence is:
7444> →→19- → -7406 → -14831 → -22256
Each term in the sequence is obtained by subtracting 7425 from the previous term.
It's important to note that this solution assumes a linear pattern in which the same subtraction value is applied to each term. However, without additional context or information about the sequence, there could be alternative patterns or interpretations.

The slope of the line below is -4. Which of the following is the iS point-slope
form of the line?
\ (2, -8)
O A. y+ 8 = -4(x-2)
O B. y+ 2 =-4(x-8)
• C. y-8 = -4(x+ 2)
• D. y- 2=-4(x+ 8)
Correct option is A, the iS point-slope form of the line is y+ 8 = -4(x-2). A straight line's equation can be written as both a point slope form and a slope intercept form.
What does "point-slope form of the line" refer to?A line equation written using a single line point and the slope of the line is the simplest definition of the term "point-slope form." The slope is expressed in point form as the ratio of the change in y values to the change in x values, also known as the rise over run (x, y).
The point slope form is useful when there is a slope and one or more points are present. Standard form is often easier to employ while doing algebraic computations. Depending on our needs or our level of expertise, we can alter the form of an equation. Both the point slope form and the slope intercept form can be used to express the equation for a straight line. The point slope form highlights any point on the line as well as the slope. The slope and y-intercept of a line are only shown in slope intercept form.
Given,
the slope of line = - 4 and point = (2,-8)
The equation of line = y - yo = m (x - xo)
where m = slope and x,y are coordinates
y + 8 = - 4 (x - 2)
y + 8 = - 4x + 8
y = - 4x
Therefore, the correct answer is option A, y+ 8 = -4(x-2)

simplify log_3+log_5+log_2 32
The simplified expression of log_3+log_5+log_2 32 is 5log_3(20) by properties of logarithms
Using the logarithmic identity that states log (a × b) = log a + log b
we can simplify the expression as follows:
log_3+log_5+log_2 32 = log_3(2⁵) + log_5(2⁵) + log_2(2⁵)
= 5log_3(2) + 5log_5(2) + 5log_2(2)
= 5(log_3(2) + log_5(2) + log_2(2))
using the property that log_b(a) + log_b(c) = log_b(a × c)
= 5(log_3(2 × 5× 2))
= 5(log_3(20))
Therefore, the simplified expression is 5log_3(20).

g Given p, q, and r three propositional variables, how many different ways are for the propositional logic formula (p -> q) ^ (q -> r) ^ p to be evaluated to FALSE
Answer:
There are 7 ways in which the formula can be evaluated to False.
Step-by-step explanation:
In order to solve this problem we will need to build a truth table. In order to build the truth table, we must start by setting the possible truth values combinations. In total there must be 8 rows, which you can see on the first three columns of the attached table.
Next, it is advisable that you divide the formula in little chunks of information that will be easier to evaluate. One column can be (p->q).
Let's evaluate that first column. In general, that column can only be false if p=T -> q=F. Which happens only on the 3dr and 4th rows of the table. The rest of the statements are true.
The next column will be (q->r). The same condition is met here, but this time you take into account the values given on the q and r columns. The false values will happen only on the 2nd and 6th rows. The rest of the rows for that collumn should be true.
Finally you can test for the whole formula. the first, 4th and 5th columns must be true for the formula to be true as well, which will happen only on the first row. The rest of the rows will have at least one false statement which makes the whole row false. So the rest of the rows are false.

Is 402 a term of the sequence 8, 13, 18, 23.........?
Answer:
→402 is not a term in the given sequence.
Step-by-step explanation:
Given sequence is 8,13,18,23,...
First term = 8
Common difference = 13-8= 5
⇛18-13=5
⇛23-18=5
Since the common difference is same throughout the sequence
⇛8,13,18,23,... are in the AP.
Let nth term = 402
We know that
nth term of an AP = an = a+(n-1)d
Now,
an = 402
⇛8+(n-1)(5) = 402
⇛8+5n-5 = 402
⇛5n+3 = 402
⇛5n = 402-3
⇛5n = 399
⇛n = 399/5
n can not be rational number it should be a positive integer.

What is the equation of a parabola with vertex (-8, – 7) that passesthrough (-7, -9)?
Here in this question, we are to find the equation of the parabola.
Generally, the equation of a parabola is in the form;
\(y=a(x-h)^2\text{ + k}\)The term (h,k) represent the coordinates of the vertex.
In this case, h = -8 and k = -7
The term 'a' is simply referred to as a multipier.
Now, we insert the coordinates of the vertex into the equation and we have the following expression;
\(y=a(x-(-8))^2+(-7)\)and we have y = a(x + 8)^2 -7
To finally get the equation, we will need to calculate the value of the multiplier. The value of the multiplier can simply be calculated by substituting the value of x and y in the point through which the parabola passes.
Hence, we are substituting the values x = -7 and y = -9
So, we have;
-9 = a(-7+8)^2 -7
-9 = a(1)^2 -7
-9 = a - 7
a = -9 + 7 = -2
So our equation becomes;
y = -2(x+8)^2 - 7
we simply finish this by expanding the equation;
y = -2(x+8)(x+8) - 7
y = -2(x^2 + 16x + 64) -7
y = -2x^2 - 32x -128 -7
y = -2x^2 -32x -135
The equation of a parabola with vertex (-8, – 7) that passes through (-7, -9) is ;

State the x-values where the limit does not exist.
9514 1404 393
Answer:
x = -2x = 2Step-by-step explanation:
There are vertical discontinuities in the function at x=-2, x=2, and x=4. When looking at limits, we find the function values to be different either side of those discontinuities at x = -2 and at x = 2. Thus, limits do not exist at those points (x = {-2, 2}).
At x=4, the discontinuity is in the function definition, not in the values left or right of that point. Hence the limit does exist at x=4, but the function is not continuous there.
