If f (x) = (x^2 − 3)^4, then f '(1) =
Answer:
f'(1) = -64
Step-by-step explanation:
To find f'(1), we will be finding the f'(x) first which means the first derivative of f(x), we can find the derivative by using chain rule to this function.
The formula of chain rule is:
[tex]\displaystyle f(u) = u^n \to f'(u) = nu^{n-1}\cdot u'[/tex]
In simple explanation, we derive normally (power rule) then multiply by the derivative of inside (u).
Applying the formula, we will have:
[tex]\displaystyle{f'(x)=4(x^2-3)^{4-1}\cdot (x^2-3)'}\\\\\displaystyle{f'(x)=4(x^2-3)^{3}\cdot 2x}\\\\\displaystyle{f'(x)=8x(x^2-3)^{3}}[/tex]
Substitute x = 1 in the f'(x):
[tex]\displaystyle{f'(1)=8(1)(1^2-3)^3}\\\\\displaystyle{f'(1)=8(1-3)^3}\\\\\displaystyle{f'(1)=8(-2)^3}\\\\\displaystyle{f'(1)=8(-8)}\\\\\displaystyle{f'(1)=-64}[/tex]
question 4(multiple choice worth 5 points) (04.02 lc) two functions, a and b, are described as follows: function a y
The rate of change of function A is 3 times the rate of change of function B.
What is rate of change of a function?To determine the slope of a graphed function, we use the average rate of change formula: Divide the change in y-values by the change in x-values to determine the average rate of change. Identifying changes in measurable parameters like average speed or average velocity calls for the knowledge of the average rate of change.Now,
Given:
For Function A, y = 9x + 4For Function B, rate of change = 4 and y intercept = 4To find: The number of times the rate of change of function A is, as compared to the rate of change of function B.
Finding:
According to the information given,
Rate of change = 3, i.e., b = 3 for function By- intercept = 4, i.e., c = 4Thus, by the slope-intercept form, given by: y = bx + c, the rate of change for function B is given by:
y = 3x + 4
Now, on comparison with function A, we can see that the rate of change of the function A is exactly thrice of that of function B.
Hence, The rate of change of function A is 3 times the rate of change of function B.

19. A carpenter cut the top section of a window frame with a 40º angle on each end. The side pieces each have a 50º angle cut at their top ends, as shown.
Will the side pieces of the frame be parallel?_____________________
How do you know?
If a carpenter cut the top section of a window frame with a 40º angle on each end. The side pieces each have a 50º angle cut at their top ends, as shown. Yes the side pieces of the frame will be parallel. How i know is that both side are equal or parallel.
ParallelThe interior angles are the same in measure and the sum of the interior angles have to be 180°.
The two side pieces on both the right and left hand side are equal in measure. The sides can be parallel only if the sum of both side angles is equal to 180°
Hence,
One side of the interior angle=40º+50º
One side of the interior angle=90°
Both side of the interior angle=90°+90°
Both side of the interior angle=180°
Hence,
180°=180°, the sides are parallel
Therefore Yes the side pieces of the frame will be parallel. How i know is that both side are equal or parallel.

PABc = 1/12.
Two dice are tossed.
Assume that each possible outcome has 1/36.
Let A be the event the probability of getting some of the faces showing is 6.
A = 1,5,5,12,44,23,3
Let B be the event that the face showing one die is twice on the other.
That is,
B =1,22,12,44,23,66,3
There are 36-6=30 events in Bc
However, A and Bc will only be having 3 pairs together = 1,55,13,3
Therefore,
PABc = 3/36
PABc = 1/12.
How many outcomes are possible for the sum of the faces showing?
There are countless outcomes that could occur. The sum of the faces shown has an endless number of outcomes. This is due to the fact that there are an endless number of ways to flip a coin, which will produce various combinations on the faces that are displayed. The sum of the faces and the tails has an endless number of outcomes. There are only two outcomes that can occur while tossing a coin because the total number of outcomes is always even.

Explaining How to Use Linear Palls and
Imagine two lines intersect. How can the properties of
linear pairs and vertical angles help to determine the
angle measures created by the intersecting lines?
Explain.
Angles that are vertical are opposite ones that only have one common vertex.
Two sets of vertical angles result from the intersection of two lines.
When two lines intersect, we obtain two linear pairs, which are two angles that make a straight line.
Knowing one of the angles formed when two lines intersect enables us to determine that the vertical angle, which is the angle directly across from it, has the same measurement.
Additionally, we know that the angle next to it, which creates a linear pair, will be added to it (add to 180), allowing us to discover its measure by subtracting it from 180.
Since they are both vertical angles, the remaining missing angle will be the same as this supplementary angle.

choose the correct answer to fill in the blank. an outlier is an observation which is less than iqr or greater than q3 ( )times iqr.
Outliers are any observations that fall more than 1.5 IQR below Q1 or more than 1.5 IQR above Q3.
Outliers:
While observing the data in the observations some of data may fall outside the general scope of the other observations. Such observations are called outliers.
Given,
An outlier is an observation which is less than IQR or greater than Q3 times IQR.
Here we need to find in Q1 and Q3 place variations.
When we use the IQR method of identifying outliers to set up a “fence” outside of Q1 and Q3. Any values which fall outside of the identified fence are considered outliers.
To build this fence we take 1.5 times the IQR and then subtract this value from Q1 and add this value to Q3.
Like,
IQR = (1.5 - Q1)
IQR = (1.5 + Q3)
This gives us the minimum and maximum fence posts that we compare each observation to.
Therefore, any observations that are more than 1.5 IQR below Q1 or more than 1.5 IQR above Q3 are considered outliers.

What are the ordered pairs of the solutions for this system of equations? y=x^2-2x+3
y=-5x + 1
The ordered pairs of the solutions for this system of equations is (-2,11) and (-1,6)
Two integers written in a certain order make up an ordered pair. As a result, we may define an ordered pair as a pair of components that appear in brackets and in a specific order.
These equations are composed of a line and a parabola. The intersection points between them must be located:
[tex]y=x^2-2x+3[/tex]
y=-5x+1
Thus,
[tex]x^2-2x+3=-5x+1[/tex]
[tex]x^2-2x+5x+3-1=0[/tex]
[tex]x^2+3x+2=0[/tex]
[tex]x^2+x+2x+2=0[/tex]
[tex]x(x+1)+2(x+1)=0[/tex]
x+2=0, x=-2
x+1=0, x=-1
Since the quadratic expression may be factored out, the following x-values represent the system's solution:
x=-2 and x=-1
Now, we may obtain the corresponding y values using either of the system's original equations. We decide to use a linear equation as an illustration:
When x =-2,

Provide three additional commonly used statistical measures for the characterization of data dispersion.
The three additional commonly used statistical measures for the characterization of data dispersion are: Standard Deviation, Interquartile Range and Range.
What is dispersion in statistics?Dispersion in statistics refers to how far the data deviates from the mean.When measures of central tendency are insufficient to explain the data, it is highly helpful. Consider the case where the mean is the same across two completely different datasets. Then, in order to explain the variation in the datasets, we employ metrics of dispersion.Now,
The most common examples of statistical metrics of dispersion include:
Standard Deviation: A measurement of how widely apart data are from the mean is the standard deviation. It is the most typical method of measuring dispersion.Interquartile Range: The middle 50% of observations are described by the interquartile range (IQR). The middle 50% of observations are widely separated if the interquartile range is big. Extreme values have no impact on it. Consequently, is helpful when the extreme values are not precisely recorded.Range: The range of data is the distance between the largest and smallest observation. It does not use all of the observations in a data collection and is particularly sensitive to outliers. Therefore, giving the minimum and maximum values rather than the range is more instructive.Hence, The three additional commonly used statistical measures for the characterization of data dispersion are: Standard Deviation, Interquartile Range and Range.
