The regular expression is ^(a(aa)*b)$.
Find Regular expression for odd 'a's, ending with 'b'?To create a regular expression for the language L = {w = {a,b}* | w has an odd number of 'a's and ends with 'b'}, we can use the following expression:
^(b|(a(aa)*b))$
Breaking it down:
^ indicates the start of the string.
(b|(a(aa)*b)) matches either 'b' or a sequence of 'a's followed by an odd number of 'a's and 'b'.
(aa)* matches zero or more pairs of 'a's.
$ indicates the end of the string.
This regular expression ensures that the string starts with 'b' or a sequence of 'a's, followed by an odd number of 'a's, and ends with 'b'. Any additional characters or sequences in between are not allowed.
Please note that regular expressions can have different notations and conventions depending on the context or programming language you're using. The expression provided here follows a general pattern that should work in most cases.

(02.02 MC) Triangle ABC is shown. A is at negative 2, 1. B is at negative 1, 4. C is at negative 4, 5. If triangle ABC is reflected over the x‐axis, reflected over the y‐axis, and rotated 180 degrees, where will point B' lie? (−1, 4) (1, −4) (4, −1) (−4, 1)
Answers
Answer:
(-1,4)
Step-by-step explanation:
Point B in the pre-image is at (-1,4).
If triangle ABC is reflected over the x‐axis, the y-coordinate changes to its negative value, thus we have the transformation:
Next, if the point (-1,-4) is reflected over the y‐axis, the x-coordinate changes to its negative, Thus, we have the transformation:
Finally, a rotation by 180 degrees will give the coordinates of B' as:
The point B' will lie in (-1, 4) [ the same place as B].
The coordinates of point B' are \((-1,4)\). So, the first option is correct.
Given:
The vertices of a triangle ABC are \(A(-2,1), B(-1,4)\) and \(C(-4,5)\).
Triangle ABC is reflected over the x‐axis, reflected over the y‐axis, and rotated 180 degrees.
To find:
The point B'.
Solution:
If a figure reflected over x-axis, then
\((x,y)\to (x,-y)\)
\(B(-1,4)\to B_1(-1,-4)\)
If a figure reflected over y-axis, then
\((x,y)\to (-x,y)\)
\(B_1(-1,-4)\to B_2(-(-1),-4)\)
\(B_1(-1,-4)\to B_2(1,-4)\)
If a figure rotated 180 degrees about the origin, then
\((x,y)\to (-x,-y)\)
\(B_2(1,-4)\to B'(-(1),-(-4))\)
\(B_2(1,-4)\to B'(-1,4)\)
So, the coordinates of point B' are \((-1,4)\).
Therefore, the first option is correct.

13% × 1,989 =
13 ÷ 100 × 1,989 =
13 × 1,989 ÷ 100 =
25,857 ÷ 100 =

2,247.57 - 1,989 = 258.57
Answer:
2247.57
Explanation:
100% ↔ 1989
1% ↔ 19.89
increased by 13% - 100% + 13% = 113%
113% ↔ [ 19.89 * 113 ]
113% ↔ 2247.57
or simply: 1989 * (100+13)% ↔ 1989 * 113% ↔ 2247.57

3x + 3 = 25 − 3x x = Find a two-decimal-place approximation of each solution. (Enter your answers as a comma-separated list. If there is no solution, enter NO.
Answers
The two-decimal-place approximation of the solution to the equation is x ≈ 3.67.
To find the solutions to the equation 3x + 3 = 25 - 3x, we can start by simplifying the equation:
3x + 3x = 25 - 3
6x = 22
x = 22/6
Using a calculator or performing the division, we can find the decimal approximation of x:
x ≈ 3.67
Therefore, the two-decimal-place approximation of the solution to the equation is x ≈ 3.67.
we want to isolate the variable x on one side of the equation. We can do this by combining like terms and performing algebraic operations to simplify the equation.
By adding 3x to both sides of the equation, we eliminate the variable on the right side, and by subtracting 3 from both sides, we isolate the variable on the left side. This leads us to the equation 6x = 22.
To find the value of x, we divide both sides of the equation by 6, which gives us x = 22/6. This is the exact solution of the equation.
However, since the question asks for two-decimal-place approximation, we can use a calculator or perform the division to find x ≈ 3.67.

Find the limit of the sequence: an 2n2+4n+3 8n2 +6n+6 Limit____
Answers
To find the limit of the sequence, we need to take the value of "n" to infinity.
So, let's divide both the numerator and denominator by the highest power of "n", which is "2n^2".
an = (2n^2 + 4n + 3) / (8n^2 + 6n + 6)
Now, as "n" tends to infinity, the terms with lower powers of "n" become insignificant. Therefore, we can neglect the terms "4n" and "6n" in the numerator and denominator.
an = (2n^2 + 3) / (8n^2 + 6n + 6)
Now, taking the limit of the sequence as "n" tends to infinity:
limit = lim(n → ∞) [(2n^2 + 3) / (8n^2 + 6n + 6)]
Using the rule of L'Hopital's rule, we can differentiate the numerator and denominator separately with respect to "n".
limit = lim(n → ∞) [(4n) / (16n + 6)]
As "n" tends to infinity, the denominator becomes very large, and the term "6" becomes insignificant. So,
limit = lim(n → ∞) [(4n) / (16n)]
limit = lim(n → ∞) [1 / 4]
limit = 1/4
Therefore, the limit of the sequence is 1/4.

The value of x in the given equation will be 2/5
From the data,
We have to determine the value of x.
The given equation is: 18x-16=-12x-4
For determining the value of x, we will first shift the like terms on one side of the equation.
So, for solving the value of x we will shift the terms containing x and the constant on both sides of the equation.
So, shifting -12x from the right-hand side of the equation to the left-hand side of the equation,
We will get it as:
18x+12x = -4+16
30x=12

a trough of water is 8 merets deep and its ends are in the shape of an isoceles triangle whoses width is 5meters and height is 2 meters. if water is being pumped in at a constant rate of 6 m sec, at what rate is the ehigt of the water changing when the water has a height of 120 cm
Answers
Answer:
when the water has a height of 120 cm, or 1.2 meters, the rate at which the height of the water is changing is 2.4 m/s.
Step-by-step explanation:
To find the rate at which the height of the water is changing, we need to use calculus.
We can define the height of the water at any given time as a function h(t). The rate at which the water is being pumped into the trough can be represented as a constant function f(t) = 6 m/s. The rate at which the water's height is changing at any given time is equal to the derivative of the height function with respect to time, or h'(t).
The volume of water in the trough is equal to the area of the base of the trough (which is in the shape of an isoceles triangle) times the height of the water. The volume of the water in the trough can also be represented as a function V(h).
We can set up the following equation to represent the relationship between the volume of water in the trough and the height of the water:
V(h) = (1/2) * b * h * h
where b is the base of the isoceles triangle (5 meters).
We can also set up the following equation to represent the relationship between the volume of water being pumped into the trough and the rate at which the water's height is changing:
V'(h) = f(t)
We can substitute the expression for V(h) into the equation for V'(t) and solve for h'(t):
h'(t) = f(t) / [(1/2) * b]
= (6 m/s) / [(1/2) * 5 m]
= 6 m/s / (1/2) * (5 m)
= 6 m/s / (2.5 m)
