Describe the transformation that was performed on parallelogram EFGH to create parallelogram E’F’G’H’. Show or explain how you got your answer.
Answers
The transformation of (x,y) from EFGH to E'F'G'H' is (x + 4, y - 2).
We can see that the coordinates of E are (3,6) and the coordinates of E' are (7,4)
Hence, we can see that,
x coordinate is increased by 3 and y-coordinate is decreased by 2.
Also, the coordinates of F are (5,6) and the coordinates of F' are (9,4).
Here also, x coordinate is increased by 3 and y-coordinate is decreased by 2.
This is happening in all vertices of the parallelogram.
Hence,
The transformation of (x,y) from EFGH to E'F'G'H' is (x + 4, y - 2).

A projectile is launched upward with a velocity of 288 feet per second from the top of a 35-foot platform. What is the maximum height attained by the projectile?
Answers
The maximum height attained by the projectile is 403.79 meters = 1324.77 feet.
The height formula has the following formula:
h = h₀ + v₀t - gt²/2
In which h₀ is the initial height, v₀ is the initial speed and g = 9.8 m/s² is the gravity.
Given, We are working with the gravity in meters, so we must convert the feet measures to meters.
Each feet has 0.3048 meters.
So 288 feet per second = 87.78 meters per second.
35 foot = 10.66 meters.
This means that:
h₀ = 10.66, v = 87.78
so,
h(t) = 10.66 + 87.78 - 4.9t²
The maximum height is attained at the moment of time in which the velocity is 0. The velocity is the derivative of the height. So:
v(t) = h'(t) = -9.8t+87.78
v(t) = 0
9.8t = 87.78
t = 8.96
The maximum height is attained at 8.96s. This height is
h(t) = 10.66 + 87.78t - 4.9t²
h(8.96) = 10.66 + (87.78×8.96) - (4.9×(8.96)²)
= 10.66 + 786.50 - 393.37
= 403.79 m
The maximum height attained by the projectile is 403.79 meters = 1324.77 feet.

Melissa and brain are at the base of a mountain.melissa hikes to a location 27 meters above sea level.brain hikes to a location 21 meters below sea level. what us the diffrence if the hikers altitudes?
Answers
The point at the base of the mountain is described as point zero, that is they are still at sea level. If Melissa now moves to a position 27 metres above sea level, that is positive 5, assuming we are now measuring along a vertical number line. Brian however moves to a location which is 21 metres below sea level, or negative 21 along the vertical number line. Since we are measuring distances, the distance from point zero to both hikers' new position will be measured in absolute values only, that is both distances will be measured as positive.
Hence the distance between Melissa and Brian is;
Distance = 27 + 21
Distance = 48
The difference in altitude between both hikers is 48 metres

Answers
You have 7 ones
3 fives

6 twenties
This is a total of 7+3+2+6 = 18 bills
First we want to know the probabilitity that you will draw a five
P(five dollar bill) = number of fives/ total = 3 / 18 = 1/6
Now we have 7 ones
2 fives
2 tens
6 twenties
This is a total of 7+2+2+6 = 17 bills left ( assuming you get to keep the bill)

You spin the spinner twice.5243What is the probability of landing on a number less than 3 and then landing on a 5?Simplify your answer and write it as a fraction or whole number.Submit
Answers
To get the probability of an event, we need two things:
1. The total number of possibilities
2. The total number of possibilities considered favorable
For the first event A which is landing on a number less than 3, we only have one favorable possible which is landing on 2.
For the second event B which is landing on a 5, we also only have one favorable possible which is landing a 5 itself.
Now, for both events, the total number of possibilities is 4.
So, the probability of landing on a number less than 3 is 1/4 while the probability of landing on a 5 is also 1/4.
So, the probability of landing on a number lesser than 3 AND landing on a 5 is:

Tim bought a new computer for his office for $1200. He read that thecomputer depreciates (loses value) at a rate of $200 per year. What will bethe value of the computer after 3 years? *
Answers
If each year the computer loses $200 of it's value, in 3 years it'll have lost 3 times that amount i.e. $600.
So, after 3 years the computer will have $600 less the value than when Tim bought it:
[tex]1200-600=600[/tex]After 3 years, the value of the computer will be $600
The loss of the computer's value can be model as:
[tex]y=-200x+1200[/tex]Where 1200 is the initial value, 200 is how much it's devalued per year. 'x' represents the years since Tim bought the computer and 'y' represents it's value after 'x' years.

The Lofoten Islands in Norway (one of Mr. Maier's favorite places) has a latitude of 68.4711 ° north of the equator. What is the linear speed as the earth rotates at that latitude? Use 3961.3 miles for the radius of the earth.
Answers
The equations are the linear velocity and angular moment respectively.
Since we have that the rotation of the Earth takes 24 hours, we transform it into seconds, that is:
[tex]24\cdot60\cdot60=86400[/tex]So, it has a period of 86400 seconds.
We now, transform the radius to the IS (from miles to meters), that is:
[tex]3961.3\text{miles}=6375.1\operatorname{km}[/tex]And, since the latitude is 68.4711° we solve in the function given at the start, that is:
[tex]w=\frac{2\pi}{86400}\Rightarrow w=7.272205217\cdot10^5[/tex]Then we divide this value by the time it takes to do a revolution of the Earth, the previously calculated 86400 seconds, that is:
[tex]v=wr\Rightarrow w=(7.272205217\cdot10^{-5})(6375.1)[/tex][tex]\Rightarrow v\approx0.464[/tex]So, the linear velocity at that latitude is approximately 0.464 Km/s.
