A: -12
B: -6
C: 0
D: 12
Answers
The sum of -6 and its additive inverse is (C: 0.)
The additive inverse of a number is the value that, when added to the original number, yields a sum of zero. The additive inverse of -6 is 6.
To find the sum of -6 and its additive inverse, simply add -6 and 6 together:
-6 + 6 = 0

Write the expression out
factor it

cancel out all everything that is the same and appears on both the top and the bottom
Cancel out:
(x+1)
(x)
(x)
leaves you with
\(\frac{3(x-1)}{6}\)
3 goes into 6 '2' times so the 3 in the numerator cancels out too. The 6 in the denominator turns into a 2
This leaves you with the final answer of
\(\frac{x-1}{2}\)

which expression can be used to find the surface area of the following square pyramid
Answers
Answer:
a. 36+15+15+15+15
Step-by-step explanation:
The base of the pyramid is a square. We know that all sides of a square are equal so if we multiply the two sides of the base square(6*6) we get 36.
The area of a triangle can be found with the formula (b*h)/2. If we input the given values of 5 and 6 into our equation, then (5*6)/2 is 15 and since there are 4 triangles in the square pyramid, you multiply 15 by 4 (or add 15+15+15+15), and add the 36 from the base square.

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.
\(\displaystyle \int\limits^1_4 {\frac{\cos x}{1 + \frac{e}{x}}} \, dx\)
Step 2: Integrate Pt. 1
[Integrand] Rewrite:\(\displaystyle \begin{aligned}\int\limits^1_4 {\frac{\cos x}{1 + \frac{e}{x}}} \, dx & = \int\limits^1_4 {\frac{x \cos x}{x + e} \, dx \leftarrow \\\end{aligned}\)
Step 3: Integrate Pt. 2
Identify variables for u-substitution.
Set u:\(\displaystyle u = x + e\)[u] Differentiate [Derivative Rules and Properties]:
\(\displaystyle du = dx\)
Step 4: Integrate Pt. 3
[Integral] Apply Integration Method [U-Substitution]:\(\displaystyle \begin{aligned}\int\limits^1_4 {\frac{\cos x}{1 + \frac{e}{x}}} \, dx & = \int\limits^1_4 {\frac{x \cos x}{x + e} \, dx \\& = \int\limits^{x = 1}_{x = 4} {\frac{(u - e) \cos (u - e)}{u} \, du \leftarrow \\\end{aligned}\)[Integral] Rewrite [Integration Property - Addition/Subtraction]:
\(\displaystyle \begin{aligned}\int\limits^1_4 {\frac{\cos x}{1 + \frac{e}{x}}} \, dx & = \int\limits^1_4 {\frac{x \cos x}{x + e} \, dx \\& = \int\limits^{x = 1}_{x = 4} {\frac{(u - e) \cos (u - e)}{u} \, du \\ & = \int\limits^{x = 1}_{x = 4} {\cos ( u - e)} \, du - \int\limits^{x = 1}_{x = 4} {\frac{e \cos (u - e)}{u}} \, du \leftarrow \\\end{aligned}\)[2nd Integral] Rewrite [Integration Property - Multiplied Constant]:
\(\displaystyle \begin{aligned}\int\limits^1_4 {\frac{\cos x}{1 + \frac{e}{x}}} \, dx & = \int\limits^{x = 1}_{x = 4} {\cos ( u - e)} \, du - e \int\limits^{x = 1}_{x = 4} {\frac{\cos (u - e)}{u}} \, du \leftarrow \\\end{aligned}\)
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:\(\displaystyle v = u - e\)[v] Differentiate:
\(\displaystyle dv = du\)
Step 6: Integrate Pt. 5
Solve the 1st integral using basic integration techniques listed under "Calculus":
\(\displaystyle \begin{aligned}\int\limits^{x = 1}_{x = 4} {\cos (u - e)} \, du & = \int\limits^{x = 1}_{x = 4} {\cos v} \, dv \\& = \sin v \bigg| \limits^{x = 1}_{x = 4} \\& = \sin (u - e) \bigg| \limits^{x = 1}_{x = 4} \\& = \sin (x) \bigg| \limits^{x = 1}_{x = 4} \\& = \sin 1 - \sin 4\end{aligned}\)
Step 7: Integrate Pt. 6
To solve the 2nd integral, we use the same methods as "Step 6":
\(\displaystyle\begin{aligned}\int\limits^{x = 1}_{x = 4} {\frac{\cos (u - e)}{u}} \, du & = \int\limits^{x = 1}_{x = 4} {\frac{\sin e \sin u + \cos e \cos u}{u}} \, du \\& = \sin e \int\limits^{x = 1}_{x = 4} {\frac{\sin u}{u}} \, du + \cos e \int\limits^{x = 1}_{x = 4} {\frac{\cos u}{u}} \, du \\& = \sin (e) \text{Si} (u) \bigg| \limits^{x = 1}_{x = 4} + \cos (e) \text{Ci} (u) \bigg| \limits^{x = 1}_{x = 4} \\\end{aligned}\)
\(\displaystyle\begin{aligned}\int\limits^{x = 1}_{x = 4} {\frac{\cos (u - e)}{u}} \, du & = \sin (e) \text{Si} (x + e) \bigg| \limits^{x = 1}_{x = 4} + \cos (e) \text{Ci} (x + e) \bigg| \limits^{x = 1}_{x = 4} \\& = \bigg[ \sin (e) \text{Si} (1 + e) - \sin (e) \text{Si} (4 + e) \bigg] + \bigg[ \cos (e) \text{Ci} (1 + e) - \cos (e) \text{Ci} (4 + e) \bigg] \\\end{aligned}\)
Step 8: Integrate Pt. 7
Combine our 2 integral values to obtain a final answer:
\(\displaystyle \int\limits^1_4 {\frac{\cos x}{1 + \frac{e}{x}}} \, dx & = \int\limits^{x = 1}_{x = 4} {\cos ( u - e)} \, du - e \int\limits^{x = 1}_{x = 4} {\frac{\cos (u - e)}{u}} \, du \\\begin{aligned}& = \sin 1 - \sin 4 - e \bigg[ \sin (e) \text{Si} (1 + e) - \sin (e) \text{Si} (4 + e) + \cos (e) \text{Ci} (1 + e) - \cos (e) \text{Ci} (4 + e) \bigg] \\& \approx \boxed{0862854} \\\end{aligned}\)
∴ we have evaluated the given special definite integral.

1) What is the value of r?
Answers
Answer:
r=4-2\sqrt{2}
Step-by-step explanation:
Let's set up an equation! (most cringe phrase ever, but hey, it works)
Because this is a square, we can do something like this: \(\frac{r}{\sqrt{2}}\)+r=2
If we multiply all sides by \(\sqrt{2}\), then we get \(r+r\sqrt{2} = 2\sqrt{2}\)
Time to solve it! (you could've gotten here another way, tho)
\(r(1+\sqrt{2} )=2\sqrt{2}\)
\(r=\frac{2\sqrt{2} }{1+\sqrt{2} }\)
Rationalizing the denominator, we get \(r=4-2\sqrt{2}\)

A coach calculated the mean and the mode of the number of points scored by 6 players.
• mean: 7 points
mode: 8 points
How many points did player 5 score?
Answers
Because 8+8+8+6+7+5=42
Then divide that by 6 to get the mean - so 42/6=7 so that’s the correct mean
Explanation:
Mean = average
Equation: total points scored/total players
Mean=7+8+6+8+?+8/6
The mean is given: 7
So plug it in:
7=(7+8+6+8+?+8)/6
Factor to solve:
Add all the numbers together to leave just the missing number (?)
7=(37+?)/6
To get rid of the 6 multiply it over to the other side
6x7=37+?
42=37+?
Now subtract the 37 to the other side to find the missing number (?)
42-37=?
5=?
Now let’s check:
7+8+6+8+(5)+8=42
Add:
42
Now divide by 6
42/6=
7
Is 7 the mean they gave us? Yup!

Answers
Answer:

Step-by-step explanation:
2.5(4^2 ÷ 3.2 – 10(0.2) + 3)– 5.2
2.5(16 ÷ 3.2 – 10(0.2) + 3) – 5.2
Next, he will perform multiplication and division inside parentheses, left to right.
2.5(5 – 10(0.2) + 3) – 5.2 . . . . . Bryan's next step
2.5(5 – 2 + 3) – 5.2
Then, he will finish evaluating inside parentheses by performing addition and subtraction left to right.
2.5(3 + 3) – 5.2
2.5(6) – 5.2
With parentheses evaluated, now we do multiplication and division, left to right.
15 – 5.2
Finally, addition and subtraction left to right.

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)
Answers
Answer:
Sure, I'll explain the cosine rule and sine rule in simple terms:
The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.
Here's an example of how to use the cosine
Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.
Using the cosine rule:
a^2 = b^2 + c^2 - 2bc * cosA
where A is the angle opposite side a, we can plug in our values and solve for a:
a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)
a^2 = 64 + 36 - 96 * 0.707
a^2 = 10.56
a = sqrt(10.56)
a = 3.25 (rounded to two decimal places)
Therefore, the length of side a is approximately 3.25 units.
