what point do we get when we rotate $(3,2\sqrt 3)$ around the point $(2,\sqrt 3)$ by $60^\circ$ counterclockwise?
The new point we will get P(\(1,2\sqrt{3}\)) when we rotate the point \((3,2\sqrt 3)\) around the point (2, \(\sqrt{3}\)) by 60⁰ counterclockwise.
Rotating point A \((3,2\sqrt 3)\)\((3,2\sqrt 3)\) around point O\((2,\sqrt 3)\) by 60⁰ counterclockwise.
Let us get point P as result.
so, assuming O is the center of a circle which has radius = r
r = \(\sqrt{(2-3)^2 + (\sqrt{3}-2\sqrt{3})^2 }\)
or r = 2
And point A and P(x,y) are on the circumference of the circle.
so, the coordinates of point P(x,y) will as follows
x = Oₓ + (Aₓ-Oₓ)cosθ - (Ay-Oy)sinθ
or x = 2 + (3-2)cos60⁰ - \(\sqrt{3}\)sin60⁰ = 2+1/2-3/2 = 1
And y = Oy + (Aₓ-Oₓ)sinθ + (Ay-Oy)cosθ
y = \(\sqrt{3}\) + \(\sqrt{3} /2\) + \(\sqrt{3} /2\) = \(2\sqrt{3}\)
so, P(\(1,2\sqrt{3}\)}
Therefore, the new point we will get P(\(1,2\sqrt{3}\)) when we rotate the point \((3,2\sqrt 3)\) around the point (2, \(\sqrt{3}\)) by 60⁰ counterclockwise.

Please help 60 points for a rapid answer-In the figure below which of the following is true in circle E?
Answer:
all 3 options are true : A, B, C
Step-by-step explanation:
warning : it has come to my attention that some testing systems have an incorrect answer stored as right answer for this problem.
they say that A and C are correct.
but I am going to show you that if A and C are correct, then also B must be correct.
therefore, my given answer above is the actual correct answer (no matter what the test systems say).
originally the information about the alignment of the point F in relation to point E was missing.
therefore, I considered both options :
1. F is on the same vertical line as E.
2. F is not on the same vertical line as E.
because of optical reasons (and the - incomplete - expected correct answers of A and C confirm that) I used the 1. assumption for the provided answer :
the vertical line of EF is like a mirror between the left and the right half of the picture.
A is mirrored across the vertical line resulting in B. and vice versa.
the same for C and D.
this leads to the effect that all 3 given congruence relationships are true.
if we consider assumption 2, none of the 3 answer options could be true.
but if the assumptions are true, then all 3 options have to be true.
now, for the "why" :
remember what congruence means :
both shapes, after turning and rotating, can be laid on top of each other, and nothing "sticks out", they are covering each other perfectly.
for that to be possible, both shapes must have the same basic structure (like number of sides and vertices), both shapes must have the same side lengths and also equally sized angles.
so, when EF is a mirror, then each side is an exact copy of the other, just left/right being turned.
therefore, yes absolutely, CAD is congruent with CBD. and ACB is congruent to ADB.
but do you notice something ?
both mentioned triangles on the left side contain the side AC, and both triangles in the right side contain the side BD.
now, if the triangles are congruent, that means that each of the 3 sides must have an equally long corresponding side in the other triangle.
therefore, AC must be equal to BD.
and that means that AC is congruent to BD.
because lines have no other congruent criteria - only the lengths must be identical.

Step-by-step explanation:
x^2 = 18
Take the square root of each side

a family decides to have children until it has three chil-dren of the same gender. assuming p(b)5p(g)5.5, what is the pmf of x5the number of children in the family?
The pmf of X = the number of children in the family is
1/4 + 3/8 + 3/8 =1
It is given that,
a family decides to have children until it has three children of the same gender i.e. BBB or GGG.
X can take the values {3,4,5}
and we know that
P(X = 3) + P(X = 4) + P(X = 5) = 1
We will find each term one by one,
P(X = 3) = (\(\frac{1}{2} * \frac{1}{2} * \frac{1}{2}\))*2
= \(\frac{1}{8}\) * 2
P(X = 3) = \(\frac{1}{4}\)
P(X = 4) = (\(\frac{1}{2} * \frac{1}{2} * \frac{1}{2} * \frac{1}{2}\))*6
= (\(\frac{1}{16}\)) * 6
P(X =4) = \(\frac{3}{8}\)
P(X = 5) = (\(\frac{1}{2} * \frac{1}{2} * \frac{1}{2} * \frac{1}{2} * \frac{1}{2}\))*12
= (\(\frac{1}{32}\))* 12
P(X = 5) = \(\frac{3}{8}\)
Therefore the pmf equation implies,
\(\frac{1}{4} + \frac{3}{8} + \frac{3}{8}\) = \(\frac{32}{32}\) = 1.

Write the inverse L.T, for the Laplace functions L −1 [F(s−a)] : a) F(s−a)= (s−a) 21 b) F(s−a)= (s−a) 2 +ω 2ω
5) The differential equation of a system is 3 dt 2 d 2 c(t) +5 dt dc(t) +c(t)=r(t)+3r(t−2) find the Transfer function C(s)/R(s)
a) To find the inverse Laplace transform of F(s - a) = (s - a)^2, we can use the formula:
L^-1[F(s - a)] = e^(at) * L^-1[F(s)]
where L^-1[F(s)] is the inverse Laplace transform of F(s).
The Laplace transform of (s - a)^2 is:
L[(s - a)^2] = 2!/(s-a)^3
Therefore, the inverse Laplace transform of F(s - a) = (s - a)^2 is:
L^-1[(s - a)^2] = e^(at) * L^-1[2!/(s-a)^3]
= t*e^(at)
b) To find the inverse Laplace transform of F(s - a) = (s - a)^2 + ω^2, we can use the formula:
L^-1[F(s - a)] = e^(at) * L^-1[F(s)]
where L^-1[F(s)] is the inverse Laplace transform of F(s).
The Laplace transform of (s - a)^2 + ω^2 is:
L[(s - a)^2 + ω^2] = 2!/(s-a)^3 + ω^2/s
Therefore, the inverse Laplace transform of F(s - a) = (s - a)^2 + ω^2 is:
L^-1[(s - a)^2 + ω^2] = e^(at) * L^-1[2!/(s-a)^3 + ω^2/s]
= te^(at) + ωe^(at)
c) The transfer function C(s)/R(s) of the given differential equation can be found by taking the Laplace transform of both sides:
L[3d^2c/dt^2 + 5dc/dt + c] = L[r(t) + 3r(t-2)]
Using the linearity and time-shift properties of the Laplace transform, we get:
3s^2C(s) - 3s*c(0) - 3dc(0)/dt + 5sC(s) - 5c(0) = R(s) + 3e^(-2s)R(s)
Simplifying and solving for C(s)/R(s), we get:
C(s)/R(s) = 1/(3s^2 + 5s + 3e^(-2s))
Therefore, the transfer function C(s)/R(s) of the given differential equation is 1/(3s^2 + 5s + 3e^(-2s)).

A one-year Treasury bill yields 4.5% and the expected inflation
rate is 3%. Calculate, precisely, the expected real rate of
interest.
The expected real rate of interest can be calculated by subtracting the expected inflation rate from the yield of the Treasury bill. In this case, the expected real rate of interest is 1.5%.
The real rate of interest represents the return on an investment adjusted for inflation. It indicates the actual purchasing power gained from an investment after accounting for the erosion of value due to inflation. To calculate the expected real rate of interest, we subtract the expected inflation rate from the nominal interest rate.
In this scenario, the one-year Treasury bill yields 4.5%, which is the nominal interest rate. The expected inflation rate is 3%. To determine the expected real rate of interest, we subtract the expected inflation rate from the nominal interest rate: 4.5% - 3% = 1.5%.
Therefore, the expected real rate of interest is 1.5%. This means that after adjusting for the expected inflation rate of 3%, the investor can expect a real return of 1.5% on their investment in the one-year Treasury bill.

if the area of the shaded region shown below is 120 square units, and the height of the line segment above the horizontal axis is 4 units, what is point a?
Point A is located at (4, 4) in the coordinate plane.With these dimensions, we can determine that Point A is located at (4, 4) in the coordinate plane.
To find the coordinates of point A, we need to consider the properties of the shaded region. The shaded region consists of a rectangle and a triangle. We know that the area of the shaded region is 120 square units, and the height of the line segment above the horizontal axis is 4 units.
The rectangle's area is given by its length multiplied by its width. Since the height of the rectangle is 4 units, we can deduce that the length of the rectangle is also 4 units. Therefore, the width of the rectangle can be found by dividing the total area of the shaded region by the length of the rectangle.
Subtracting the width of the rectangle from the total width of the shaded region will give us the base of the triangle. Since the triangle is isosceles, the base length is equal to the height of the rectangle.

precalculus b dba given a vertical asymptote and a horizontal asymptote, how would you begin to find an expression for a rational function?
By finding the vertical and horizontal asymptotes, you can use them to help find an expression for the rational function
To find an expression for a rational function given a vertical asymptote and a horizontal asymptote, start by recognizing that the general form of a rational function is f(x) = (ax + b)/(cx + d), where a, b, c, and d are all constants.
Next, use the given information to solve for a, b, c, and d in the equation. The vertical asymptote represents the x-values at which the denominator of the equation equals zero, so set cx + d equal to zero and solve for x. Similarly, the horizontal asymptote can be found by setting ax + b equal to the asymptote’s y-value.
Once both equations are solved for x, substitute the x-values back into the equation for the rational function and solve for the corresponding a, b, c, and d values.
A vertical asymptote occurs when the denominator of the rational function is equal to zero, so you can set the denominator equal to zero and solve for the variable to find the vertical asymptote.
A horizontal asymptote occurs when the degree of the numerator and denominator are equal, so you can look at the leading coefficients of the numerator and denominator to find the horizontal asymptote.
