Transformation involves changing the location of a shape
The image of P after the transformation is: (-5,-2)
The vertices are given as:
[tex]\mathbf{P = (-8,6)}[/tex]
[tex]\mathbf{Q = (1,-3)}[/tex]
[tex]\mathbf{R = (-6,-3)}[/tex]
The rule of reflection across line y = 2 is:
[tex]\mathbf{(x,y) \to (x,4-y)}[/tex]
So, the image of P, after the reflection is:
[tex]\mathbf{P' = (-8,4-6)}[/tex]
[tex]\mathbf{P' = (-8,-2)}[/tex]
The rule of translation 3 units right is:
[tex]\mathbf{(x,y) \to (x + 3,y)}[/tex]
So, we have:
[tex]\mathbf{P" = (-8 + 3,-2)}[/tex]
[tex]\mathbf{P" = (-5,-2)}[/tex]
Hence, the image of P after the transformation is: (-5,-2)

The temperature at 8:20 P.M. is 3degreesC. If it has dropped 1degreesC per minute, what was the temperature at 7 : 50 P.M.?
Answer:
33°C
Step-by-step explanation:
The time between 8:20 and 7:50 is 30 minutes. If it drops 1°C per minute you multiply this number by the amount of minutes which would be 30. This becomes 30°C. Then add the 3° it's at now to become 33°C.
Solve for x in the equation 3 x squared minus 18 x + 5 = 47.
x = 3 plus-or-minus StartRoot 23 EndRoot
x = 3 plus-or-minus StartRoot 51 EndRoot
x = 3 plus-or-minus StartRoot 41 EndRoot
x = 3 plus-or-minus StartRoot 5 EndRoot
Answer:
first option
Step-by-step explanation:
3x² - 18x + 5 = 47 ( subtract 5 from both sides )
3x² - 18x = 42 ( divide through by 3 )
x² - 6x = 14
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 3)x + 9 = 14 + 9
(x - 3)² = 23 ( take square root of both sides )
x - 3 = ± [tex]\sqrt{23}[/tex] ( add 3 to both sides )
x = 3 ± [tex]\sqrt{23}[/tex]

Evaluate each function for the given input values. For f (x)=x 2- 5, find f (x) when x= 0 and when x= 3
Answer:
f(x) = x² - 5
so f(0) = 0² - 5 = 0 - 5 = - 5
and f(3) = 3² - 5 = 9 - 5 = 4
Kathy had $10 and gave half of it to her brother. She then gave a third of the remaining
amount to a friend. How much money will Kathy have left?
Kelly has $10
- half: $10 - 1/2 x $10
$10 - $5 = $5
- one third: $5 - 1/3 x $5
$5 - $1.6667... or $5 - $1 and 2/3 = $3.33... or $3 and 1/3 or $10/3
She will have left $3.33 left, or $3 and 1/3
A plane flies at a speed 580 km/hr at a constant height of 16 km. How rapidly is the angle of elevation to the plane changing when the plane is directly above a point 125 km away from the observer?
Answer:
-0.584 rad/hr, rounded to the nearest 1000th
Step-by-step explanation:
Let D = D(t) = the horizontal distance from the observer to the plane at time t in units of km.
Let E = E(t) = the angle of elevation at time t in units of Radians.
Then, by geometry,
tan(E) = 16 / D, and furthermore, we have that
tan(E) = 16 * D^(-1)
d/dt (tan(E)) = d/dt ( 16 * D^(-1))
sec^2 (E) * dE/dt = 16(-1)(D^(-2)) * dD/dt
( sqrt(D^2 + 16^2) / D )^2 * dE/dt = -16 (D^(-2)) * dD/dt
(D^2 + 16^2)/D^2 * dE/dt = -16 (D^(-2)) * dD/dt
dE/dt = -16 (D^(-2)) * dD/dt * D^2 / (D^2 + 16^2)
dE/dt = -16 (dD/dt) / (D^2 + 16^2)
dE/dt = -16 (580 km/hr) / (125^2 + 16^2), at time t such that D(t) = 125 km,
dE/dt = (-9280 / 15881) rad/hr
dE/dt = -0.584 rad/hr, rounded to the nearest 1000th
The director of student life at a university wants to estimate the proportion of undergraduate students who regularly park a car on campus. Describe how to select a stratified random sample of approximately 100 students. Explain your choice of strata and why stratified random sampling might be preferred in this context.
Random sampling involves selecting a sample where each element of the sample have an equal probability of selection.
From the question, we understand that the director wants to make use of a stratified random sampling technique.
The stratified random sampling technique involves selecting the sample (i.e. 100 students), by dividing the whole undergraduate students into groups (i.e. strata), and then select a proportion from each group.
A possible way to achieve this, is as follows:
Divide the undergraduate students in faculties (assume the university has 10 faculties)Then select 10 students from each of the 10 faculties.With the above highlights, the director would be able to make the selection.

Answer: Sin(©)=4/5
Step-by-step explanation: Cos(©)=3/5
Sin(©)=?
By Trigonometric identity,
Sin²(©) + Cos²(©) = 1
Sin²(©) = 1- Cos²(©)
Cos²(©) = (3/5)² = 9/25
Sin²(©) = 1- 9/25 = 16/25
Taking the root of both sides,
√(Sin²(©)) = √(16/25)
Hence, Sin(©) = 4/5

Mr. Cash bought d dollars worth of stock. During the first year, the value of the stock tripled. The next year, the value of the stock decreased by $1200. (a) Write an expression in terms of d to represent the value of the stock after two years. (b) If an initial investment is $1,000, determine its value at the end of 2 years.
Answer:
1. 3D-1200 = value after two years.
2. $1800 = value after two years
Step-by-step explanation:
When the value of D triples, 3 times D = 3D. value of the stock after two years decreased, would be the -1200.
When you get the value of 1,000 you can plug it in to get 3 (1000) - 1200 = Stock price after two years
