Examples of algebra skills with reversal actions: Addition and subtraction, Multiplication and division
In algebra, the concept of inverse operations is important in solving equations. Two examples of algebra skills that involve inverse operations are addition and subtraction, and multiplication and division. Addition and subtraction are inverse operations because adding a number and then subtracting the same number results in the original value. Similarly, multiplication and division are inverse operations because multiplying a number and then dividing by the same number results in the original value. Inverse operations are useful in solving equations because they allow us to isolate a variable by undoing the operations that were performed on it.

Answer:
2 sqrt(5) OR 4.5
Step-by-step explanation:
You have to know Pythagorean theorem to solve this question.
a^2 + b^2 = c^2
To use this theorem you have to have a right triangle. There are two right triangles in your image. The lower (larger) one has two sides labeled, so you can use Pythagorean thm to find the third side. There's a short cut, bc some right triangles have easy-to-memorize lengths of the sides. 3-4-5 is one of these number sets. A multiple of this is 6-8-10. We could've solved:
b^2 + 8^2 = 10^2
But it would've come out the same. The unlabeled side is 6.
We can use the 6 and the 4 on the smaller right triangle and use the Pythagorean thm again to solve for x.
4^2 + x^2 = 6^2
16 + x^2 = 36 subtract 16 from both sides.
x^2 = 20
Take the square root of both sides.
sqrt (x^2) = sqrt 20
x = 2 sqrt(5) which is approximately 4.472.
2 sqrt(5) is an exact answer if that is what they are asking for. 4.472 is an approximation to the nearest thousandth. It would be 4.47 to the nearest hundredth or 4.5 to the nearest tenth.

Solve the initial boundary value problem ut = 2uxx for x ∈ (-π, π], t ∈ [0, + [infinity]), ux(0, t) = ux,(1,t) = 0, for t ∈ [0, + [infinity]), u(x,0) = π^2 – π^2 for r ∈ [ -π, π]
Answers
The solution to the initial boundary value problem is u(x,t) = 1/π.
To solve the initial boundary value problem ut = 2uxx for x ∈ (-π, π], t ∈ [0, + [infinity]), ux(0, t) = ux,(1,t) = 0, for t ∈ [0, + [infinity]), u(x,0) = π^2 – π^2 for r ∈ [ -π, π], we can use the method of separation of variables.
Assume u(x,t) = X(x)T(t), then we have:
X''(x) + λX(x) = 0, T'(t) + 2λT(t) = 0
where λ is a separation constant. The general solution for the spatial equation is X(x) = A sin(nx) + B cos(nx), where n = sqrt(λ) and A, B are constants. Since u(0,t) = u(1,t) = 0, we have A = 0 and B cos(nπ) = 0, which implies n = kπ for k = 1, 2, 3, ... Thus, the spatial eigenfunctions are X_k(x) = cos(kπx), and the corresponding eigenvalues are λ_k = -(kπ)^2.
The time equation can be solved as T(t) = Ce^(-2λ_k t), where C is a constant. Therefore, the general solution for the initial boundary value problem is:
u(x,t) = Σ C_k cos(kπx) e^(-2(kπ)^2 t)
where the sum is taken over all k = 1, 2, 3, .... To determine the constants C_k, we use the initial condition u(x,0) = π^2 – π^2 = 0. This gives:
Σ C_k cos(kπx) = 0
Since the eigenfunctions form an orthogonal set on [-π, π], we can multiply both sides by cos(mπx) and integrate over [-π, π] to obtain:
C_m = 0 for m = 1, 2, 3, ...
Thus, the only non-zero constant is C_0, which can be determined using the normalization condition:
1 = ∫_(-π)^π (u(x,t))^2 dx = C_0^2 π^2
Therefore, C_0 = 1/π. Thus, the solution to the initial boundary value problem is:
u(x,t) = (1/π) cos(0πx) e^(-2(0π)^2 t) = 1/π e^0 = 1/π
In conclusion, the solution to the initial boundary value problem is u(x,t) = 1/π.

of the legs) is 21 yds. The city council would like to add a path along the longest side of the park (the
hypotenuse). How long would the path be? Show your work. Don’t forget to label your answer. See page
Answers
Answer:
To solve this problem, we can use the Pythagorean theorem, which states that for any right triangle with legs of length a and b and hypotenuse of length c, a² + b² = c².
We are given that one of the legs has a length of 21 yds, and the area of the park is 294 yd². We can use the area formula for a right triangle to find the length of the other leg:
area = 1/2 * base * height
294 = 1/2 * 21 * height
294 = 10.5 * height
height = 28
So the other leg has a length of 28 yds. Now we can use the Pythagorean theorem to find the length of the hypotenuse:
c² = a² + b²
c² = 21² + 28²
c² = 441 + 784
c² = 1225
c = √1225
c = 35
Therefore, the length of the path along the longest side of the park would be 35 yds

let f(x)=∫x1sin(t)tdt. find the indicated derivative.
Answers
The function F(x) has a derivative f'(x) = sin(x) - xcos (x). This is accomplished by employing the chain rule and the basic calculus theorem.
The calculus fundamental theorem can be used to derive the derivative of f(x).
Let x1sin(t)dt equal F(x). The fundamental theorem of calculus states that F'(x) = sin (x).
Let g(x) now equal x. The chain rule then states that f'(x) = g' (x) F'(x)= g'(x)sin(x)=cos (x).
Therefore, f'(x) = sin(x) - xcos is the derivative of f(x) (x).
F(x) has a derivative f'(x) = sin(x) - xcos (x). Applying the chain rule and the calculus's fundamental theorem will get this result. The integrand assessed at the integral's upper limit is equivalent to the derivative of a definite integral, according to the calculus fundamental theorem. According to the chain rule, the derivative of a function made up of two functions is equal to the sum of the derivatives of the inner and outer functions. The inner function in this instance is sin(t), while the outer function is x. Thus, by using the chain rule and the fundamental theorem of calculus, we can determine that f'(x) = sin(x) - xcos (x)

solution for 3/4x - 12 = -18?
Answers
Answer:
x = -8
Step-by-step explanation:
Add 12 on both sides
You get 3/4x = -6
Multiply 4/3 on both sides
You get x = -24/3
Simplify and you get -8.
Answer:
x=-8
Step-by-step explanation:
The reason why x is -8 is because
The first step is to isolate the x
To isolate the x you got to add 12 to both sides
\(\frac{3}{4}\)x-12+12=-18+12
the -12 gets canceled out by the positive twelve so all thats left now is
\(\frac{3}{4}\)x=-18+12,-18+12 is -6 so its \(\frac{3}{4}\)x=-6
The second step is to divide
now you have to divide by \(\frac{3}{4}\) on both sides
\(\frac{\frac{3}{4} x}{\frac{3}4} } =\frac{-6}{\frac{3}{4} }\)
which \(\frac{3}{4}\) is taken out on the left side because its divided by itself so all thats left is a one,while on the right side -6 divided by three-fourths is -8

A batch of bottles were packed in 25 boxes with 12 bottles in each box. If the same batch is packed using 20 bottles in each box, how many boxes would be filled?
Answers
hey ,
here is your answer,
_______________
Let the number of boxes filled, by using 20 bottles in each box, be x.
The following table is obtained.
______________________
| Number of bottles. 12. 20 |
| |
| Number of boxes 25. x. |
---------------------------------------------
More the number of bottles, lesser will be the number of boxes.
Hence, the number of bottles and the number of boxes required to pack these are inversely proportional to each other.
Therefore,
12 × 25 = 20× x
Hence, the number of boxes required to pack these bottles is 15.
Answer:
The answer is 15 Box.
No of bottles = 25 boxes × 12 bottles
= 300 bottles
So there were total 300 bottles in a box.
Now If 20 bottles are filled ina box then
no. of box required = 300/20
And answer is 15 boxes

Leon has already run 1 mile on his own, and he expects to run 3 miles during each track practice. Write an equation that shows the relationship between the practices p and the distance d.
Answers
Answer:
d = 1 + 3p
Step-by-step explanation:
Leon already ran 1 miles on his own and he is expected to cover a distance d of 3 miles during each practice. The number of practices is expressed as p and the distance covered is expressed as d.
For every track practice he is expected to cover a distance of 3 miles. Recall he has already cover 1 mile on his own.
Therefore, the relationship between the practices p and the distance d can be expressed as follows.
number of track practice = p
distance covered = d
The distance covered d in miles is 1 miles plus the number of track practice p multiply by 3
d = 1 + 3p
