The value of the sum of the functions f(x) and g(x), (f + g)(x) is 5x³ - 4x.
What is a function?The outputs for a certain set of inputs can be referred to as a function.
A function's inputs are referred to as its independent variables, while its outputs are referred to as its dependent variables.
Given, f(x) = x³ + 8 and g(x) = 4x³ - 5x - 8.
Let, f(x) = x³ + 0x + 8.
We know, (f + g)(x) = f(x) + g(x).
Therefore, (f + g)(x) = (x³ + 0x + 8) + (4x³ - 5x - 8).
(f + g)(x) = x³ + 4x³ + 0x - 4x + 8 - 8.
(f + g)(x) = 5x³ - 4x.

Chloe is making a large table in the shape of a trapezoid, as shown. She needs to calculate the area of the table. She is making the longest side of the table twice as long as the table's width. Complete parts a and b below.
a. The number in the bottom box is 15 yd. The number in the top box is 9 yd.
b. The area of the table is 90 yd².
How to calculate the area of a trapezoid?In Mathematics and Geometry, the area of a trapezoid can be calculated by using this mathematical equation (formula):
Area of trapezoid, A = ½ × (a + b) × h
Where:
a and b represent the base areas of a trapezoid.h represent the height of a trapezoid.Part a.
Since Chloe is making the longest side of the table to be twice as long as the table's width, the number in the bottom box can be calculated as follows;
Bottom box = 2 × 7.5
Bottom box = 15 yd.
For the number in top box, we have:
Top box = 15 - (3 + 3)
Top box = 9 yd.
Part b.
Now, we can determine the area of the table as follows;
Area of table = ½ × (a + b) × h
Area of table = ½ × (15 + 9) × 7.5
Area of table = 90 yd².

A new car is purchased for 24900 dollars. The value of the car depreciates at 6.75% per year. To the nearest tenth of a year, how long will it be until the value of the car is 15900 dollars?
Answer:
5.5 years
Step-by-step explanation:
24900 times 6.75% = 1,680.75
so this is how much it goes down per year, but we have to find it were the price reaches 15900. so 9000-1680.75=
7,319.25( one year)
7,319.25-1680.75 = 5,638.5 (second year)
5,638.5-1680.75= 3,957.75 (third year)
3,957.75-1680.75 = 2,277 (fourth year)

Find the value of r.
a pencil that is 4 in. long (starting at x=2) and has a density function of rho(x)=5/x oz/in.
The mass of the pencil is approximately 5.49 ounces.
To find the mass of the pencil, we can integrate the density function over the length of the pencil.
The density function is given by rho(x) = 5/x oz/in.
We want to find the mass of the pencil, so we integrate the density function from x = 2 (the starting point of the pencil) to x = 6 (the endpoint of the pencil).
The integral is ∫[2, 6] (5/x) dx.
Evaluating the integral, we have:
∫[2, 6] (5/x) dx = 5 ln(x) ∣[2, 6] = 5 ln(6) - 5 ln(2) = 5 (ln(6) - ln(2)).
Using the property of logarithms, we can simplify this to:
5 ln(6/2) = 5 ln(3) ≈ 5 (1.098) ≈ 5.49 oz.
The mass of the pencil is approximately 5.49 ounces.

Use a maclaurin series in this table to obtain the maclaurin series for the given function. F(x) = x cos(5x)
By using a maclaurin series to obtain the maclaurin series for the given function is F(x) = x cos(5x) = \(1 - 25x^2/2! + 625x^4/4! - 15625x^6/6! + ...\)
To obtain the Maclaurin series for the function f(x) = x cos(5x), we need to write the Maclaurin series for cos(5x). The Maclaurin series for cos(x) is: \(cos(x) = 1 - x^2/2! + x^4/4! - x^6/6! + ...\)
Using this formula, we can substitute 5x for x and obtain the Maclaurin series for cos(5x): cos(5x) =\(1 - (5x)^2/2! + (5x)^4/4! - (5x)^6/6! + ...\)
\(= 1 - 25x^2/2! + 625x^4/4! - 15625x^6/6! + ...\)
We can substitute this series into the original function f(x) = x cos(5x) and obtain its Maclaurin series: f(x) = x cos(5x)
\(= x[1 - 25x^2/2! + 625x^4/4! - 15625x^6/6! + ...]\)
\(= x - 25x^3/2! + 625x^5/4! - 15625x^7/6! + ...\)
This is the Maclaurin series for the function f(x) = x cos(5x). It is obtained by substituting the Maclaurin series for cos(5x) into the original function and simplifying the resulting series. Maclaurin series are useful for approximating functions using polynomials. By truncating the series after a certain number of terms, we can obtain a polynomial that approximates the original function to a certain degree of accuracy. The accuracy of the approximation depends on the number of terms in the series that are used. The more terms we include, the more accurate the approximation will be.

The earth is about 12,760 km in diameter and about 150 million kilometers away from the sun. The nearest stars besides the Sun are about 4.3 light-years away (1 light-year equals = 9.5 times 10 Superscript 12 Baseline km 9.5×1012 km). At a scale of 1 to 10 billion, the Sun would be about the size of a grapefruit. How big and how far away would the Earth be on this scale? How far would the nearest stars (besides the Sun) be?
Answer:
0.00128 m = ;
15 m;
950000 m (950 km)
Step-by-step explanation:
The scale to be used is 1 to 10 billion (1 : 10,000,000,000)
The earth is about 12,760 km (12760000 m) in diameter and about 150 million km (150000000000 m) away from the sun.
Therefore, using this scale, we just have to divide the diameter and distance of the earth from the sun by 10,000,000,000:
Diameter = 12760000 / 10000000000 = 0.00128 m
Distance = 150000000000 / 10000000000 = 15 m
The nearest stars besides the Sun are about 4.3 light-years away (1 light-year equals = \(9.5 * 10^{12} km\) = 9500000000000000 m). Therefore, using the scale:
Distance = 9500000000000000 / 10000000000 = 950000 m = 950 km
Consider the equation. Select the operation needed to perform each step.

how do i graph y=9-x
Answer:
We can rewrite the equation in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. To do this, we can rearrange the terms as follows:y = 9 - xy = -1x + 9
This gives us a slope of -1 and a y-intercept of 9. We can plot the y-intercept at (0, 9) and use the slope to find another point on the line. The slope tells us that for every increase of 1 in x, the value of y decreases by 1. So, starting from (0, 9), we can move one unit to the right and one unit down to get another point (1, 8). We can continue this process to find more points or connect the two points we already have to draw a line.

The resulting graph should be a straight line that starts at the point (0, 9) on the y-axis and intersects the x-axis at the point (9, 0). The line slants downward from left to right.
Here, we have,
We can rewrite the equation in slope-intercept form,
y = mx + b,
where m is the slope and b is the y-intercept.
To do this, we can rearrange the terms as follows:
y = 9 - x
y = -1x + 9
This gives us a slope of -1 and a y-intercept of 9.
We can plot the y-intercept at (0, 9) and use the slope to find another point on the line.
The slope tells us that for every increase of 1 in x, the value of y decreases by 1.
So, starting from (0, 9), we can move one unit to the right and one unit down to get another point (1, 8).
We can continue this process to find more points or connect the two points we already have to draw a line.
To graph the equation y = 9 - x, you can follow these steps:
Step 1: Create a table of values. Choose some x-values and substitute them into the equation to find the corresponding y-values. For simplicity, let's choose three values for x:
x | y = 9 - x
0 | 9 - 0 = 9
3 | 9 - 3 = 6
6 | 9 - 6 = 3
Step 2: Plot the points. Use the x-values from the table and their corresponding y-values to plot the points on the graph. The points are (0, 9), (3, 6), and (6, 3).
Step 3: Draw the line. Connect the plotted points with a straight line. The line should pass through all the plotted points.
The resulting graph should be a straight line that starts at the point (0, 9) on the y-axis and intersects the x-axis at the point (9, 0). The line slants downward from left to right.

for an f-curve with df = (20, 5), find f0.025
The value of f(0.025) is approximately ±2.086 for an f-curve with df = (20, 5).
The t-distribution is a way of describing a set of observations where most observations fall close to the mean, and the rest of the observations make up the tails on either side. It is a type of normal distribution used for smaller sample sizes, where the variance in the data is unknown.
To find f(0.025) for an f-curve with df = (20, 5), we need to use a t-distribution table.
First, we need to determine the critical value for a two-tailed test with a significance level of 0.05 and 20 degrees of freedom (df).
Looking at the t-distribution table, we find that the critical value is approximately ±2.086.
Next, we can use the formula for the t-distribution to calculate f(0.025):
f(0.025) = t(0.025, 20) = ±2.086
