Differentiate the function with respect to x.

Answers

Differentiation of the function [tex]f(x) = (-x^{2} - 4)x^{5}[/tex] with respect to [tex]x[/tex] is [tex]f'(x) = -7x^{6} - 20x^{4}[/tex].

What is the differentiation of the function?

A function differentiation is a method of displaying the rate of change of a function at a given moment. It is the slope of the tangent line at a point on a graph for real-valued functions.

We have,

                                     [tex]f(x) = (-x^{2} - 4)x^{5}[/tex]

By simplifying the given function, we get

                                      [tex]f(x) = -x^{7} - 4x^{5}[/tex]

Now, we will differentiate the given function with respect to [tex]x[/tex].

                                    [tex]\frac{d}{dx} f(x) = \frac{d}{dx} (-x^{7} - 4x^{5})[/tex]

                                    [tex]f'(x) = \frac{d}{dx} (-x^{7}) - \frac{d}{dx} (4x^{5}))[/tex]

                                     [tex]f'(x) = -7x^{6} - 20x^{4}[/tex]

Hence, differentiation of the given function with respect to [tex]x[/tex] is [tex]f'(x) = -7x^{6} - 20x^{4}[/tex].

A cone has a volume of 2411.52 cubic millimeters and a radius of 12 millimeters. What is its height? Use ​ ≈ 3.14 and round your answer to the nearest hundredth.

Answers

The height of the cone given the volume of 2411.52 cubic millimeters and a radius of 12 millimeters is 16 millimeters.

How to find height of a cone?

Volume of a cone = 2411.52 cubic millimetersRadius of the cone = 12 millimeters

Volume of a cone = 1/3πr²h

2411.52 = 1/3 × 3.14 × 12 x 12 × h

2411.52 = 1/3 × 3.14 × 144h

2411.52 = 452.16h / 3

cross product

7,234.56 = 452.16h

divide both sides by 452.16

h = 7,234.56 / 452.16

h = 16 millimeters

In conclusion, the height of the cone is given by 16 milliliters.

Many Texas cities have experienced substantial growth in population over the last 20 years. The growth of Houston, Texas, since 2015 is shown in the scatterplot. A least-squares equation that relates the number of years since 2015 to the population of that year (in millions) is given by Population = 0.025 (year) + 2.01.

Based on the residual plot, is a linear model suitable for modeling the population growth of Houston?

A linear model is suitable because a pattern is evident in the residual plot.
A linear model is not suitable because the residuals do not cluster around zero.
A linear model is not suitable because the residual plot shows a curved pattern.
A linear model is suitable because the residuals seem to be randomly scattered.

Answers

Based on the given residual plot, as regards the linear model, we can say that; A linear model is not suitable because the residual plot shows a curved pattern.

What is a residual Plot?

A residual plot is a plot that shows the difference between the observed response and the fitted response values.

The ideal residual plot is usually called the null residual plot, and it shows a random scatter of points that form an approximately constant width band around the identity line.

When it comes to finding out if a linear model will be suitable, we can say that the points will form a pattern when the model function is not correct.

Now, you might be able to transform variables or even add polynomial and interaction terms in order to remove the pattern.

Now, looking at the given graph, we can say that a linear model is not suitable because from the definitions above, we can see that the residual plot shows a curved pattern.

For the given points (6, y) and (-8, 4) having slope = 1/7 the value of y = 10.

What is the slope of a line?

A line's slope, also known as its gradient, is defined as the value of a line's steepness or direction in a coordinate plane. Slope can be calculated using various methods given a line equation or the coordinates of points on a straight line.

If P(a, b) and Q(c, d) are two given points on a coordinate plane, then the slope of line PQ can be computed using the formula

Given,

In a psychology class, 30 students have a mean score of 87.7 on a test. Then 21 more students take the test and their mean score is 67.7.

Here we need to find the mean score of all students.

In order order to find the mean score, we have to calculate the total score of the students by multiplying the mean score by the number of students then we get,

=> 30 x 87.7 = 2631

Similarly, the total score for 21 students is,

=> 21 x 67.7 = 1421.7

So, the 51 students, cumulative score is

=> 2631 + 1421. 7 = 4052.7

Therefore, the mean score is calculated as,

=> 4052.7/51

=> 79.464

When we round off the value into one decimal place then we get

[ (a - b)² = a² - 2ab + b² ]

x² - 2 x (13/2)x + (13/2)² - (13/2)² + 31 = 0

(x - 13/2)² + 169/4 + 31 = 0

(x - 13/2)² + (293/4) = 0
