Step-by-step explanation:
*Note:
The problem is too big to fit all work. I will assume that you know how to do basic calculus.
Step 1: Define
Identify given.
[tex]\displaystyle \int\limits^1_4 {\frac{\cos x}{1 + \frac{e}{x}}} \, dx[/tex]
Step 2: Integrate Pt. 1
[Integrand] Rewrite:[tex]\displaystyle \begin{aligned}\int\limits^1_4 {\frac{\cos x}{1 + \frac{e}{x}}} \, dx & = \int\limits^1_4 {\frac{x \cos x}{x + e} \, dx \leftarrow \\\end{aligned}[/tex]
Step 3: Integrate Pt. 2

Step 5: Integrate Pt. 4
Identify variables for u-substitution for the 1st integral.
Use another variable besides u to avoid confusion with earlier substitutions.
Set v:[tex]\displaystyle v = u - e[/tex][v] Differentiate:
[tex]\displaystyle dv = du[/tex]
Step 6: Integrate Pt. 5
Solve the 1st integral using basic integration techniques listed under "Calculus":
[tex]\displaystyle \begin{aligned}\int\limits^{x = 1}_{x = 4} {\cos (u - e)} \, du & = \int\limits^{x = 1}_{x = 4} {\cos v} \, dv \\& = \sin v \bigg| \limits^{x = 1}_{x = 4} \\& = \sin (u - e) \bigg| \limits^{x = 1}_{x = 4} \\& = \sin (x) \bigg| \limits^{x = 1}_{x = 4} \\& = \sin 1 - \sin 4\end{aligned}[/tex]
Step 7: Integrate Pt. 6
To solve the 2nd integral, we use the same methods as "Step 6":
[tex]\displaystyle\begin{aligned}\int\limits^{x = 1}_{x = 4} {\frac{\cos (u - e)}{u}} \, du & = \int\limits^{x = 1}_{x = 4} {\frac{\sin e \sin u + \cos e \cos u}{u}} \, du \\& = \sin e \int\limits^{x = 1}_{x = 4} {\frac{\sin u}{u}} \, du + \cos e \int\limits^{x = 1}_{x = 4} {\frac{\cos u}{u}} \, du \\& = \sin (e) \text{Si} (u) \bigg| \limits^{x = 1}_{x = 4} + \cos (e) \text{Ci} (u) \bigg| \limits^{x = 1}_{x = 4} \\\end{aligned}[/tex]
[tex]\displaystyle\begin{aligned}\int\limits^{x = 1}_{x = 4} {\frac{\cos (u - e)}{u}} \, du & = \sin (e) \text{Si} (x + e) \bigg| \limits^{x = 1}_{x = 4} + \cos (e) \text{Ci} (x + e) \bigg| \limits^{x = 1}_{x = 4} \\& = \bigg[ \sin (e) \text{Si} (1 + e) - \sin (e) \text{Si} (4 + e) \bigg] + \bigg[ \cos (e) \text{Ci} (1 + e) - \cos (e) \text{Ci} (4 + e) \bigg] \\\end{aligned}[/tex]
Step 8: Integrate Pt. 7
Combine our 2 integral values to obtain a final answer:
[tex]\displaystyle \int\limits^1_4 {\frac{\cos x}{1 + \frac{e}{x}}} \, dx & = \int\limits^{x = 1}_{x = 4} {\cos ( u - e)} \, du - e \int\limits^{x = 1}_{x = 4} {\frac{\cos (u - e)}{u}} \, du \\\begin{aligned}& = \sin 1 - \sin 4 - e \bigg[ \sin (e) \text{Si} (1 + e) - \sin (e) \text{Si} (4 + e) + \cos (e) \text{Ci} (1 + e) - \cos (e) \text{Ci} (4 + e) \bigg] \\& \approx \boxed{0862854} \\\end{aligned}[/tex]
∴ we have evaluated the given special definite integral.

Jayden wants to lay sod on his front yard and on half of his back yard. His front yard has a length of 50 feet and a width of 70 feet. His back yard has a length of 10 feet and a width of 30 feet. How many square feet of sod does Jayden need to purchase?
Answers
The first thing we must do for this case is to calculate the area of both yards.
We have then:
front yard:
A1 = (50) * (80)
A1 = 4000 feet ^ 2
Back yard:
A2 = (10) * (30)
A2 = 300 feet ^ 2
"Jayden wants to lay sod on his front yard and on half of his back yard"
Then, the total amount will be:
A = A1 + (1/2) A2
Substituting:
A = 4000 + (1/2) (300)
A = 4000 + 150
A = 4150 feet ^ 2
Answer:
jayden needs to purchase 4150 square feet of sodd
Answer:
Its an area equation. Area is length times width.
So to start, he needs 50 x 80 square feet in his front yard, BUT THAT IS ONLY HALF OF THE PROBLEM. For the front yard he needs 4000 sq. feet. For the back, it is different. He needs 10x40÷2. To first simplify, we do the multiplication. This comes to 400÷2. then it is simply 200.
Now for the easy part. Take the 4000 and add 200. Answer? 4,200.

d. {(2.9, 0), (2.9, 1), (2.9, 2), (2.9, 3)}
Answers
Answer: See in the explanation
Step-by-step explanation:
The domain is all of the X values in a set.
The range is all of the Y values in a set.
You can tell if a set of coordinate pairs is a function if each x value corresponds to 1 Y value. For example, lets say we have an x value of 3. This X value can only correspond to ONE y value. So if the x value 3 corresponded to , e.g, 4, or 7 as y values, it would not be a function because 1 x value has to have only 1 y value.
a. {(0,9), (8, 1), (-1, 9), (9, 8), (1, -1)}
* This relation is a function, because there aren't many of the same x value numbers.
* The domain is {0, 8, -1, 9, 1}. Those are all of the X values
* The range is {9, 1, 9, 8, -1} (All of the Y values)
b. {(62, -3.1), (61, -3.1), (60, -3.1), (-3.1, -3.1)}
* This relation is a function, because even though all of the y values are the same , the x values are different.
* The domain is {62, 61, 60, -3.1}.
* The range is {-3.1, -3.1, -3.1, -3.1}
c. {(123,876), (-15, 2.6), (2.6, -15), (123, 1), (-87, -0.98)}
* This relation is a function, because all of the X values are different
* The domain is {123,876, -15, 2.6, 123, -87}
* The range is {0, 2.6, -15, 1, -0.98}
d. {(2.9, 0), (2.9, 1), (2.9, 2), (2.9, 3)}
* This relation is not a function. All of the x values are the same, and for this reason, they all have different y values.
* The domain is {2.9, 2.9, 2.9, 2.9}
* The range is {0, 1, 2, 3}

Please help i give brainliest, show the work though. Susan is buying 5 and a half pies from the market. Write this amount as a mixed number, improper fraction, decimal and percent.
Answers
Answer: 5 1/2 pies as a mixed number, 11/2 as an improper fraction, 5.5 as a decimal, 550 as a percent
Step-by-step explanation:
2x5+1 11
-----------= -----
2 2
The fraction 5 1/2 is equal to 5, plus 1 divided by 2 which is equal to 5, plus 0.5 which is equal to 5.5 in decimal
5.5 x 100 = 550 percent
Given statement: Susan is buying 5 and a half pies from the market.
We already know:
The word "and" means "in addition to", which means addition (+)Therefore, the number of pies Susan bought is;
⇒ 5 and a half pies⇒ 5 + half pies∴ Half can be written as ½
⇒ 5 + ½If a whole number is being added to a fraction, we can combine them to convert the sum into mixed fraction.
⇒ 5 + ½⇒ 5 ½Therefore, 5 ½ is the fraction of pies, Susan bought.
Improper fraction:Given statement: Susan is buying 5 and a half pies from the market.
In mixed fraction: Susan is buying 5 ½ pies from the market.
To convert the mixed fraction of pies into improper fraction, simply multiply the whole number by the denominator and add the numerator to the product of the whole number and the denominator. The denominator in the mixed fraction will remain the same in the denominator.
⇒ 5 ½⇒ [(5 × 2) + 1]/2⇒ [(10) + 1]/2⇒ [11]/2 = 11/2Therefore, 11/2 is the fraction of pies, Susan bought.
Decimal:Given statement: Susan is buying 5 and a half pies from the market.
In improper fraction: Susan is buying 11/2 pies from the market.
Clearly, we can rewrite 11/2 as;
⇒ 10/2 + 1/210/2 results in getting 5 and 1/2 results in getting 0.5. Therefore,
⇒ 5 + 0.5⇒ 5.5Therefore, 5.5 is the decimal of pies, Susan bought.
Percent:Given statement: Susan is buying 5 and a half pies from the market.
In decimal: Susan is buying 5.5 pies from the market.
Simply multiply the decimal by 100 to determine the percentage of pies bought by Susan.
⇒ 5.5 pies = 5.5 x 100% = 550%
Therefore, 550% is the percent of pies, Susan bought.

What is the area, in square meters, of the trapezoid below?
Answers
Answer: 94.54 m^2 (square meters)
Step-by-step explanation: The formula for the area of a trapezoid is A = 1/2(a+b)h; where a and b are the two top sides of the trapezoid that are parallel. Let us then solve.
Let us combine both sides two maintain the overall side for "b", which is 18 + 5.1 = 23.1
Let us now add both sides (a + b.) 23.1 + 9.5 is 32.6. We can now multiply by the height. 32.6 multiplied by 5.8 is 189.08
We can now divide (or multiply by 1/2), which is 189.08 * 1/2 or 189.08/2 and that equals 94.54.
Step 1
Find the area of the Rectangle in the middle
To find the area, you have to do [tex]Length*Width[/tex]
[tex]9.5*5.8=55.1[/tex]
The area of the Rectangle in the middle is 55.1m²
Step 2
Find the area of the triangle on the right
To find the area of 1 triangle, we have to use the formula show below:
[tex]A=\frac{1}{2}* Base *Height[/tex]
Base = the part on the bottom
Height = How high the triangle is
[tex]A=\frac{1}{2} *5.1*5.8\\=\frac{1}{2} *29.58\\=14.79[/tex]
The area of the triangle on the right is 14.79m²
Step 3
Find the area of the triangle on the left
Using the formula that we used in the last question about finding the area of the triangle, we can find our answer, here is the formula:
[tex]A=\frac{1}{2}* Base *Height[/tex]
Base = the part on the bottom
Height = How high the triangle is
BUT, before finding the area of this part of the triangle, we have to first find the dimensions, we know the height, but we don't know the base, so to find the base, we will subtract 18 by 9.5 to get our base
[tex]18-9.5=8.5[/tex]
So the base of the triangle on the LEFT is 8.5m
NOW, we can find the area of the triangle on the left
[tex]A =\frac{1}{2}* 8.5*5.8\\=\frac{1}{2} *49.3\\=24.65[/tex]
So the area of the triangle on the LEFT is 24.65m²
Step 4
Add up all the areas to get final answer!
The areas of the 3 shapes are...
55.1m²
14.79m²
24.65m²
If we add these numbers up, we get 94.54m²The area of the trapezoid is 94.54m²
