Relative maxima and relative minima of the function f(x) = x^5 - 4x^3 3x^2 - 8x - 6
The relative maxima and relative minima for f(x) = x⁵ - 4x³ + 3x² - 8x - 6 is is -1.871 and 1.518
The given function is f(x) = x⁵ - 4x³ + 3x² - 8x - 6 ,now differentiation function with respect to x we get
=5x⁴ - 12x² + 6x - 8
Now solving the given equation for the critical values are:
x₁ = 0.176 + 0.73i
x₂ = 0.176 - 0.73i
x₃ = 1.518
x₄ = -1.871
Now, taking derivative of the 5x⁴ - 12x² + 6x - 8 , with respect to x we get
= 20x³ - 24x + 6
now replacing the value of x by 1.58, we get
20 * 1.58³ - 24 * 1.58 + 6
= 46.966, which is positive so it is the minima
Again replacing the value of x by -1.871, we get
=>20 * -1.871³ - 24 * -1.871 + 6
=> -169.9, which is negative so it is the maxima

If g(x)=(x+1)/(x-2) and h(x)=4-x what is the value of (goh) (-3)
The value of composition of function (goh) (-3) is [tex]\frac{8}{5}[/tex].
A function that depends on another function is referred to as a composite function. When one function is inserted into another, a composite function is produced. The definition of a composite function is a function made up of two functions, one of which acts as an independent variable for the other function. It can be defined as:
[tex](fog)(x)=f(g(x))\\(gof)(x)=g(f(x))[/tex]
When dealing with the composition of functions, the order of the functions is crucial since (f∘g)(x) is not equivalent to (g∘f)(x).
Finding the composition of function by putting x=h(x) in function g(x),
[tex](goh)(x)=g(h(x))\\\\=\frac{4-x+1}{4-x-2}\\\\=\frac{5-x}{2-x}[/tex]
Now, putting x = -3,
[tex](goh)(-3)=\frac{5-(-3)}{2-(-3)} \\\\=\frac{8}{5}[/tex]
Therefore, the value of composition of function (goh) (-3) is [tex]\frac{8}{5}[/tex] .

Pls list step by step : calculus : Use a linear approximation to estimate the value of √33. Express your answer as an exact rational number
Using linear approximation, the function y = √33 is approximated as 5.744
Linear ApproximationThe concept behind the linear approximation formula is the equation of a tangent line. We know that the slope of the tangent that is drawn to a curve y = f(x) at x = a is its derivative at that point. i.e., the slope of the tangent line is f'(a). Thus, the linear approximation formula is an application of derivatives. Let us learn more about this formula in the upcoming sections.

You had $50 you spent 10% of the money on clothe, 20% on games, and the rest on books. How much money was spent on books
Answer:
$35
Step-by-step explanation:
money on clothes is 10%, that means it's $5
you get this by dividing the 50 by 100 to figure out how much 1% is, and then multiply with 10.
money on games is 20%, that means it's $10
again, you figure out how much 1% of 50 is and then multiply by 20 to figure out what 20% is.
50 / 100 = 0.5
0.5 * 20 = 10
So far you spent $5 on clothes, $10 on games, that's $15 in total.
When the rest is spent on books, you need to see how much is left of the $50.
50 - 15 = 35
So you spent $35 on books.

Step-by-step explanation:
We know the slope formula is:
[tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
Because we already know the slope and three other points, we can let point f represent y2 and solve for it:

Solve the following system of equations by linear combination: 2x + y = 8 x – y = 4
a. The solution is (5, –2).
b. The solution is (4, 0).
c. There is no solution.
d. There are an infinite number of solutions.
The solution to the equation by linear combination is (b) The solution is (4, 0).
How to determine the solution to the equation?From the question, we have the following system of equations
2x + y = 8
x – y = 4
By linear combination, we start by eliminating one of the variables
This is done by adding the equations
So, we have
2x + x - y + y = 8 + 4
Evaluate the like terms
3x = 12
Divide both sides
x = 4
Substitute x = 4 in x – y = 4
4 – y = 4
So, we have
y = 4 - 4
Divide
y = 0
Hence, the solution is (b) (4, 0)

Select all the unique triangles that can be drawn to only have angle measures 40° and 100° and side length 3.
Answer:
None
Explanation:
A unique triangle can be defined as a triangle that can be formed in one way.
The various conditions that a triangle must satisfy so that it is unique :
a) A triangle where the length of the three sides is known or given is a unique triangle.
b) A triangle where two side lengths and their included angle is given is a unique triangle.
c) A triangle where two angles and their included side is given is a unique triangle.
d) A triangle where two angles and a non - included side length is known is a unique triangle.
In the above question, we are given angles 40°, 40° and 100 degrees
3 angles are known, no side length is given. The angles above can form a triangle called the obtuse triangle because their sum = 180° and one of the angles is great we than 90°
However, this does not satisfy the criteria that makes a triangle unique.
Therefore, no unique triangle(s) can be drawn with interior angles measuring 40°, 40°, and 100°.
A line with a slope of
4/7 passes through the points (h,10) and (–4,6). What is the value of h?
Answer:
h = 3
Step-by-step explanation:
y-6 = 4/7 (x-(-4)
y - 6 = 4/7 (x+4)
y - 6 = 4/7 x + 16/7
y = 4/7 x + 16/7 + 6
y = 4/7 x + (16+42)/7
y = 4/7 x + 58/7
10 = 4/7 x + 58/7
4/7 x = 10 - 58/7
4/7 x = (70-58)/7
4/7 x = 12/7
7/4 * 4/7 x = 12/7 * 7/4
x = 3

A line ha a lope of 4 and pae through the point (8,7). What i it equation in point-lope form?
Alo need an explanation pl
The equation in point-slope form is y=4x-25.
A line passing through the point (x 1, y1) has a slope of "m," and its point slope form is given by the equation y - y1=m (x - x1).
A horizontal line's equation is of the form y=b when it passes through the points (a, b).
Step 1: Write down the line's slope, "m," and the coordinates (x 1, y 1) of the point that is given and is on the line.
Step 2: Replace the given values in the calculation for the point slope: y - y1 = m. (x - x1).
Point-slope form is y=mx+b.
To get the equation of the line in standard form, simplify in step three.
Given, m(slope)= 4.
The point is (8,7)= (x1,y1)
y-7=4(x-8)
y-7=4x-32
y=4x-32+7
y=4x-25

What was the approximate percent of decrease in the cost of mid-level computers?
The percent of decrease is 63.16%
How to calculate the percentage of decrease?
First, we calculate the amount of decrease
= $3,800 - $1,400
= $2,400
Next we dividing the amount of decrease by original price (old price)
= $2,400 ÷ $3,800
= 0.6316

If the faculty went on a weight watchers diet plan and now weight an average of 185 pounds in 2021. The faculty's average weight loss per year : 185 pounds and 155 pounds.
How to find faculty lost pounds per year?First step is to find the difference between the initial weight and the final weight
Difference = Initial weight - Final weight
Difference = 215 pounds - 185 pounds
Difference = 30 pounds
Now let find the lost per year
2018
Lost per year = 215 pounds - 30 pounds
Lost per year = 185 pounds
