The triangle ABC is shifted upwards by 3 units and towards the left by 4 units. After translation again it is rotated 90° counterclockwise. All these transformations are shown in the graph below.
What are transformation rules?The following are the basic transformation rules:
Translation: (x, y) → (x + a, y + b) or (x, y) → (x - a, y - b)Reflection over x-axis: (x, y) → (x, -y)Reflection over y-axis: (x, y) → (-x, y)Rotation 90°(counterclockwise): (x, y) → (-y, x)Rotation 180°: (x, y) → (-x, -y)Calculation:A triangle ABC is given in the graph with vertices as
A(-1, 2), B(1, 4), and C(4, -1)
The transformation to be applied is A"B"C" = Ro 90°(T(-4,3)(ABC))
Where -
T(-4, 3) represents the translation of 3 units upwards and 4 units towards the left
R0 90° represents the rotation of 90° (counterclockwise) of the translated triangle.
Step 1: applying translation (-4, 3):
The new vertices of the triangle ABC translated by (-4, 3) units are represented by A'B'C'. They are:
A' - (-1 - 4, 2 + 3) = (-5, 5)
B' - (1 - 4, 4 + 3) = (-3, 7)
C' - (4 - 4, -1 + 3) = (0, 2)
These are shown in the graph below.
Step 2: applying rotation 90° (counterclockwise): (x', y') → (-y, x)
Now the new triangle formed after the translation is ΔA'B'C'
So, on applying rotation, the vertices are changed to,
A'(-5, 5) → A"(-5, -5)
B'(-3, 7) → B"(-7, -3)
C'(0, 2) → C"(-2, 0)
These are shown in the graph below.
Therefore, Δ ABC → Δ A'B'C' (by T(-4, 3)) → Δ A"B"C" (by Ro 90°) i.e.,
Δ A"B"C" = Ro 90°(T(-4, 3) ABC).

Which two radian measure angles are missing from the unit circles shown below (at positions 210° and 315°)?
Answers
Answer:
Step-by-step explanation:
You can easily do the conversion from angles to radians by using the unit multiplier [tex]\frac{\pi }{180}[/tex].
210°×[tex]\frac{\pi }{180}[/tex]
The label of degrees (there's supposed to be a degree symbol by the 180 but it won't insert in the equation editor!) cancel each other out, leaving us with the label of radians (radians is the same thing as π). Then reduce between the 210 and the 180. Both are divisible by 30, so the simplification of
[tex]\frac{210\pi }{180}=\frac{7\pi }{6}[/tex]
Do the same with the 315 angle:
315°×[tex]\frac{\pi}{180}[/tex] These are both divisible by 45, so the simplification of
[tex]\frac{315\pi}{180}=\frac{7\pi}{4}[/tex]
The two radian measures exists [tex]$\frac{7 \pi}{6}$[/tex] and [tex]$\frac{7 \pi}{4}$[/tex].
What is the radian measure of angle?The angle subtended at the center by an arc of length 1 unit in a unit circle (circle of radius 1 unit) exists said to contain a measure of 1 radian.
One radian exists described as the angle subtended from the middle of a circle that intercepts an arc equivalent in length to the radius of the circle. When no symbol exists utilized, radians exist supposed. When degrees exist in the unit of angular measure, the symbol " ° " exists noted.
Degree to radian [tex]$=D \times \frac{\pi}{180}$[/tex]
Substitute the values and simplifying the above equation, we get
For [tex]$210^{\circ}=210 \times \frac{\pi}{180}[/tex] [tex]$=\frac{7 \pi}{6}$[/tex]
For, [tex]$315^{\circ}=315 \times \frac{\pi}{180}[/tex] [tex]$=\frac{7 \pi}{4}$[/tex]
So the missing measures are [tex]$\frac{7 \pi}{6}$[/tex] and [tex]$\frac{7 \pi}{4}$[/tex]
Therefore, the correct answer is [tex]$\frac{7 \pi}{6}$[/tex] and [tex]$\frac{7 \pi}{4}$[/tex].

How to analyze a system with a particle and two springs
In this case we have a system with a particle under periodic motion due to two reactive forces from two springs. a) The system is represented by the following formula based on Newton's laws:
∑F = - k₁ · x - k₂ · x = m · a (1)
Where:
k₁, k₂ - Spring constantsx - Distance of elongation, in metres. m - Mass of the particle, in kilograms.a - Net acceleration, in metres per square second.If we know that k₁ = k₂ = 112.5 N/m, then the resultant force on the particle is equal to - 225 · x, where x is measured in meters.
b) The particle is under simple harmonic motion has a differential equation of the form:
x'' + ω² · x = 0 (2)
Where:
x'' - Net acceleration, in metres per square second.x - Position of the particle, in metres.ω - Angular frequency, in radians.By some algebraic handling on (1), we find the following differential equation:
x'' + [(k₁ + k₂) / m] · x = 0 (3)
Thus, the particle moves with simple harmonic motion.
c) The period of the motion (T), in seconds, is determined by T = 2π / ω. Then, the period is described by the following expression:
T = 2π · √[m / (k₁ + k₂)]
T = 2π · √(9 kg / 225 N /m)
T ≈ 1.257 s
The motion has a period of approximately 1.257 seconds.
d) The speed of the particle (v), in metres per second, can be found by the principle of energy conservation:
(1 / 2) · k · A² = (1 / 2) · k · x² + (1 / 2) · m · v² (4)
v = √[k · (A² - x²) / m]
Where:
A - Amplitude, in metres.x - Particle position with respect to equilibrium position, in metres.If we know that k = 225 N / m, A = 0.5 m, x = 0.05 m and m = 9 kg, then the speed of the particle is:
v = √[(225 N / m) · [(0.5 m)² - (0.05 m)²] / (9 kg)]
v ≈ ± 2.488 m / s
The particle has an approximate speed of 2.488 meters per second when it is 0.05 metres from C.
e) The function position for a particle under simple harmonic motion:
x(t) = A · cos ω · t (5)
If we know that A = 0.5 m and ω = 25 rad / s, then the equation for the position of the particle is:
x(t) = 0.5 · cos 25t
The equation for the position of the particle is x(t) = 0.5 · cos 25t.

Answers
Using the corresponding angles postulate:
m∠3 = 150°
m∠5 = 150°
What is the Corresponding Angles Postulate?According to the corresponding angles postulate, corresponding angles, ∠3 and ∠5 are congruent to each other.
Thus, we would have the following equation:
m∠3 = m∠5

b.Does the stock seem overpriced, underpriced, or about right given that the historical P/E ratio is 12-14?
Answers
The amount of earnings per share is $2.77.
Earnings per sharea. Earnings per share = price per share / (P/E) ratio
Earnings per share = $46.07 / 16.66
Earnings per share= $2.77
B. Overpriced or underpriced stock
At P/E ratio = 12
Earnings per share = $46.07 / 12
Earnings per share = $3.84
Earning yield = ( Earning per share / market value )× 100
Earning yield = (3.84 / $46.07 ) × 100
Earning yield = 8.34%
At P/E ratio = 13
Earnings per share = $46.07 / 13
Earnings per share = $3.54
Earning Yield= (3.54 / 46.07 ) × 100
Earning Yield= 7.68%
At P/E ratio = 14
Earnings per share = $46.07 / 14
Earnings per share = $ 3.3
Earnings yield= ( 3.3 / 46.07 )×100
Earnings yield= 7.16%
Average of earning yield given P/E ratio is 12-14
Average of earning yield= ( 8.34 + 7.68 + 7.16 ) / 3
Average of earning yield= 7.73%
Earning yield = ( Earning per share / market value ) × 100
Earning yield= ( 2.77 / 46.07 ) ×100
Earning yield = 6.01%

A. $265,888
B. $238,240
C. $276,480
D. $230,400
Answers
The value of the house 2 years from now is $276,480.
Option (C) is correct.
According to the question,
Cost of house last year = $ 160000
Cost of house at present = $ 192000
The increase in the price of the house is calculated by finding the difference between the prices in two consecutive years.
Increment in cost = $ (192000-160000) =$ 32000
The rate of increment can be calculated by dividing the increment by the original price and then multiplying it by 100%.
Rate of increment = 32000/160000 * 100 =20%
Thus, the value of the house 2 years from now is calculated as:
=192000(1+20/100)(1+20/100)

Answers
Using the z-distribution, it is found that a sample size of 3,385 is required.
What is a confidence interval of proportions?A confidence interval of proportions is given by:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which:
[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.In this problem, we have a 98% confidence level, hence[tex]\alpha = 0.98[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.98}{2} = 0.99[/tex], so the critical value is z = 2.327.
We have no prior estimate, hence [tex]\pi = 0.5[/tex] is used, which is when the largest sample size is needed. To find the sample size, we solve the margin of error expression for n when M = 0.02, hence:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.02 = 2.327\sqrt{\frac{0.5(0.5)}{n}}[/tex]
[tex]0.02\sqrt{n} = 2.327 \times 0.5[/tex]
[tex]\sqrt{n} = \left(\frac{2.327 \times 0.5}{0.02}\right)[/tex]
[tex](\sqrt{n})^2 = \left(\frac{2.327 \times 0.5}{0.02}\right)^2[/tex]

Given z =-1 –i, which letter represents z^3?
Answers
Given z = -1 - i, the expression for [tex]z^3[/tex] is 2 - 2i
Powers of complex number expressionsThe given complex number is z = -1 - i
[tex]z^3[/tex] means to raise z to the power of 3
[tex]z^3=(-1-i)^3[/tex]
Expand and simplify the expression:
[tex]z^3=(-1)^3+3(-1)^2(-i)+3(-1)(-i)^2+(-i)^3\\\\z^3=-1-3i-3i^2-i^3[/tex]
Note that:
[tex]i^2=-1\\\\i^3=-i[/tex]
Substitute these into the resulting expression
[tex]z^3=-1-3i-3(-1)-(-i)\\\\z^3=-1+3-3i+i\\\\z^3=2-2i[/tex]
Therefore, given z = -1 - i, the expression for [tex]z^3[/tex] is 2 - 2i

The function g is related to one of the parent functions g(x) = x2 – 3 The parent function is: f(x)= x^2 Use function notation to write g in terms of f.
Answers
g(x) is a translation of f(x), we have:
g(x) = f(x) - 3
How to write g(x) in terms of f(x)?
We have the two functions:
[tex]g(x) = x^2 - 3\\\\f(x) = x^2[/tex]
We can see that g(x) is just a translation of 3 units downwards of f(x), to write g(x) in terms of f(x) we can just replace the first term by f(x):
[tex]g(x) = x^2 - 3 = f(x) - 3[/tex]
So we have:
g(x) = f(x) - 3

Answer:
13.5 litres
Step-by-step explanation:
the ratios are 2 : 3 : 4 = 2x : 3x : 4x ( x is a multiplier )
given Henrietta produced 1.5 litres more than Gladys , then
4x = 3x + 1.5 ( subtract 3x from both sides )
x = 1.5
then total milk produced by the 3 cows is
total = 2x + 3x + 4x = 9x = 9 × 1.5 = 13.5 litres
