We need to use the method of partial fractions to simplify the integrand. After decomposing the rational function into partial fractions, we can then integrate each term separately to obtain the final result.
The given integral can be expressed as a sum of partial fractions. First, we factor the denominator x(x^4 + 4) as x(x^2 + 2)(x^2 - 2). Since the degree of the denominator is 5, we need to consider five partial fractions with undetermined constants A, B, C, D, and E.
The partial fraction decomposition is:
7 / (x(x^4 + 4)) = A / x + (Bx + C) / (x^2 + 2) + (Dx + E) / (x^2 - 2)
To find the values of the constants A, B, C, D, and E, we can equate the numerators on both sides of the equation and solve for each constant. Once we have determined the values of the constants, we can integrate each term separately. The integral of A / x is A ln|x|, the integral of (Bx + C) / (x^2 + 2) can be evaluated using the substitution method, and the integrals of (Dx + E) / (x^2 - 2) involve trigonometric substitutions. After integrating each term, we obtain the final result, which includes natural logarithms and trigonometric functions.

How many more minutes can mate car travel per gallon of gas then jenna's car
Mate's car can travel approximately 5 more minutes per gallon of gas compared to Jenna's car.
To determine how many more minutes Mate's car can travel per gallon of gas compared to Jenna's car, we would need additional information about the fuel efficiency or miles per gallon (MPG) for each car.
Fuel efficiency is typically measured in terms of miles per gallon, indicating the number of miles a car can travel on a gallon of gas.
To calculate the difference in travel time, we would also need to know the average speed at which the cars are traveling.
Once we have the MPG values for Mate's car and Jenna's car, we can calculate the difference in travel time per gallon of gas by considering their respective fuel efficiencies and average speeds.
If Mate's car has a fuel efficiency of 30 MPG and Jenna's car has a fuel efficiency of 25 MPG, we can calculate the difference in travel time by comparing the distances they can travel on a gallon of gas.
Let's assume both cars are traveling at an average speed of 60 miles per hour.
For Mate's car:
Travel time = Distance / Speed
= (30 miles / 1 gallon) / 60 miles per hour
= 0.5 hours or 30 minutes.
For Jenna's car:
Travel time = Distance / Speed
= (25 miles / 1 gallon) / 60 miles per hour
= 0.4167 hours or approximately 25 minutes.
Without specific information about the MPG values and average speeds of the cars, it is not possible to provide an accurate answer regarding the difference in travel time per gallon of gas between Mate's car and Jenna's car.

in isosceles triangle ABC,AB=AC.If B=55,calculate A
The measure of angle A in the isosceles triangle ABC is 62.5 degrees.
In an isosceles triangle ABC, where AB = AC, we are given that angle B (denoted as ∠B) measures 55 degrees. We need to calculate the measure of angle A (denoted as ∠A).
Since AB = AC, we know that angles A and C are congruent (denoted as ∠A ≅ ∠C). In an isosceles triangle, the base angles (the angles opposite the equal sides) are congruent.
Therefore, we have:
∠A ≅ ∠C
Also, the sum of the angles in a triangle is always 180 degrees. Hence, we can write:
∠A + ∠B + ∠C = 180
Substituting the given values:
∠A + 55 + ∠A = 180
Combining like terms:
2∠A + 55 = 180
Subtracting 55 from both sides:
2∠A = 180 - 55
2∠A = 125
Dividing by 2:
∠A = 125 / 2
∠A = 62.5
Therefore, the measure of angle A in the isosceles triangle ABC is 62.5 degrees.

(Round to the nearest tenth
Answer:25.2
Step-by-step explanation:
To find the value of x, we first need to find the missing angle value, which is 180-90-59, making it 31.
Now that we have that value, we can use SOH to find the hypotenuse.
The equation would look something like this:
\(\sin\left(31\right)=\frac{13}{x}\)
Which we can change to get the x value like this:
\(\frac{13}{\sin\left(31\right)}=x\)
This makes the X value equal to 25.241.
Since you need it as the nearest tenth, you can round it down to 25.2.
A businessman takes the 8:00 a. M. Train to work on 20 days in a month. He is surprised when the train arrives late in New York on 3 of the 20 days. Should he be surprised? Describe how you would carry out a simulation to estimate the probability that the train would arrive late on 3 or more of 20 days if New Jersey Transit’s claim is true. Do not perform the simulation
No, he should not be surprised. New Jersey Transit claims that the 8:00 a.m. train arrives late in New York on an average of 15 days a month. This means that the probability of the train arriving late on 3 or more days in a month is relatively high.
To estimate this probability, one can carry out a simulation. First, generate a list of 20 random numbers between 0 and 1. Each number represents a day in the month and the probability of the train arriving late. Next, assign each number a value of 1 if it is less than or equal to 0.15 (the probability of the train arriving late on any given day), and 0 if it is greater than 0.15. This represents the arrival status of the train on each day.
Finally, sum the list of numbers to obtain the total number of days the train arrived late. Repeat this process multiple times and calculate the probability of the train arriving late on 3 or more of the 20 days.

Mathematical trigonometric functions connect the angle of a right-angled triangle to the ratios of its two side lengths. In all areas of study that involve geometry, such as geodesy, solid mechanics, celestial mechanics, and many others, they are widely used. Fourier analysis is commonly used to study periodic events since it is one of the most fundamental periodic functions.
An essential trigonometric function that can be used to calculate the value of "x" is the tangent function.

2x+12=64
Step by step
Answer:
2x + 12 = 64
x = 26 (mark brain if this helps and is correct)
Step-by-step explanation:
to solve equations with one missing variable we must use the order of operations of equality
step 1: use the subtraction property of equality meaning subtract each side of the equation
ex: 2x + 12 - 12 = 64 - 12 (2x = 52)
step 2: use the division property of equality meaning divide each side of the equation by 2
ex: 2x/2 = 52/2 (x = 26)
step 3: check your answer by putting 26 as x because that is our answer
2(26) + 12 = 64 (multiply 2 * 26)
52 + 12 = 64 (add 52 + 12)
64 = 64 (if both sides of the equation are the same number like 64 = 64 then your answer is true meaning that x is equal to 26)

What is area of a composite shape?
the area covered by any composite shape. A composite shape is a shape in which some polygons are put together to form the required shape is called the area of composite shapes . These figures can consist of combinations of triangles, rectangles, squares etc. To determine the area of composite shapes, divide the composite shape into basic shapes such as square, rectangle,triangle, hexagon, etc.
Basically, a compound shape consists of basic shapes put together. This is also called a "composite" or "complex" shape. This mini-lesson explains the area of compound figures with solved examples and practice questions.
Here in this figure, we have two figures.
First one is rectangle and second one is triangle.
Length and breadth of the rectangle are 12 cm and 4 cm respectively.
So, area = Length × Breadth = 12 × 4 = 48 cm²
Again height of the triangle is (11-4) = 7 cm and base of the triangle is (12-6) = 6 cm.
So, area of the triangle = 1/2 × 7 × 6 = 3×7 = 21 cm²
Now if we add both area of rectangle and triangle then we will get area of the composite figure.
So, required area of the composite figure is ( 48+21) = 69 cm²

Binocular vision is used to perceive depth. When Brandon looks out into the forest, he uses binocular vision to determine how far away objects are in the forest. He uses the concept of the figure-ground relationship to identify trees and other figures in the forrest as separate from the background. The act of seeing or looking itself requires transduction. Light that hits his eyes undergoes a process called phototransduction in which light is converted to electrical signals which then move through different types of cells. Ultimately these signals are sent to a part of the brain called the occipital lobe where they are converted into an image in the brain.
Brandon's dog begins to growl as a result of natural selection. Dogs who growled at potential predators were more likely to scare away the predator and survive. As a result, the dog growls when it sees a potential predator. When Brandon's dog starts growling, Brandon becomes fearful that there might be something in the forest. As a result of this fear, his body initiates a sympathetic response, releasing epinephrine into the body. This epinephrine acts on the heart and causes his pulse to increase.
