Jupiter lighthouse , r=18 miles, A= 2*3.14*r^2
A Jupiter=2*3.14*18*18=2034.72 mi^2
Hillsborough light house, r= 28 miles,
A Hillsb=2*3.14*28*28=4923.52 mi^2
the difference is
4923.52-2034.72=2,888.80

please answer im taking the unit test on edge2021 and i need help ;(
Answer:
It would be triangle A'B'C' with points (2, -1); (0, -3); and (2, -3).
Step-by-step explanation:
If you were to translate triangle ABC down by two, then the y-value of each point would decrease by two. Hence, (2, 1) would become (2, -1); (0, -1) would become (0, -3); and (2, -1) would become (2, -3).

Step-by-step explanation:
solve x^2-3x+1=0 using completing the square method
This won't be the easiest way to do this problem but as your teacher requires it I will do it that way. But at the end I will show another way to do it with the quadratic formula.
First complete the square
x^2-3x+1=0
(x^2-3x+9/4)+1=9/4
(x-3/2)^2=9/4-1
(x-3/2)^2=5/4
x-3/2=±[tex]\sqrt{\frac{5}{4}[/tex]
x= 3/2±[tex]\frac{\sqrt5}{2}[/tex]
Done!
*Now this next way is not the way your teacher wants you to do it but I personally think its easier.
Just use the quadratic formula x=[-b±sqrt(b^2-4ac)]/2
x=[3±sqrt(9-4*1*1)]/2
x=(3±sqrt5)/2
x=3/2±sqrt5/2
We get the same answer but I think this way is easier. Now if your teacher ask for the top way just do the top way don't do the bottom because you will lose points, its just a shorter way to do things. Now I hope this helped and any additional questions about this just ask me in the comments.
The Thomas Supply Company Inc. is a distributor of gas-powered generators. As with any business, the length of time customers take to pay their invoices is important. Listed below, arranged from smallest to largest, is the time, in days, for a sample of the Thomas Supply Company Inc. invoices.
13 13 13 20 26 26 29 31 34 34 35 35 36 37 38
41 41 41 42 43 46 47 48 49 53 55 56 62 67 82
Required:
a. Determine the first and third quartiles.
b. Determine the second decile and the eighth decile.
Answer:
The answer is below
Step-by-step explanation:
When computing quartile and decile, the data must be arranged in ascending order.
Given the data points:
13 13 13 20 26 26 29 31 34 34 35 35 36 37 38 41 41 41 42 43 46 47 48 49 53 55 56 62 67 82
The numbers are arranged in ascending order. The total number of terms is 30.
a)
[tex]First \ quartile(Q_1)=\frac{1}{4}(n+1)^{th}\ term\\\\where\ n=number\ of\ terms. Hence:\\\\Q_1=\frac{1}{4}(30+1)=7.75^{th}\ term=average\ of\ 7th\ and\ 8th\ term=\frac{29+31}{2} =30\\\\Q_1=30\\\\Third \ quartile(Q_3)=\frac{3}{4}(n+1)^{th}\ term\\\\Q_3=\frac{3}{4}(30+1)=23.25^{th}\ term=average\ of\ 23rd\ and\ 24th\ term=\frac{48+49}{2} =48.5\\\\Q_3=48.5[/tex]
b)
[tex]Second \ decile(D_2)=\frac{2}{10}(n+1)^{th}\ term\\\\where\ n=number\ of\ terms. Hence:\\\\D_2=\frac{2}{10}(30+1)=6.2^{th}\ term=average\ of\ 6th\ and\ 7th\ term=\frac{26+29}{2} =27.5\\\\D_2=27.5\\\\\\Eight \ decile(D_8)=\frac{8}{10}(n+1)^{th}\ term=\frac{8}{10}(30+1)=24.8^{th}\ term\\=average\ of\ 24th\ and\ 25th\ term=\frac{49+53}{2} =51\\\\D_8=51[/tex]

Can I have some help with this? Construct a linear function that has a slope of -3 and passes through the point (-2,3).
Answer:
-3x-3
Step-by-step explanation:
We want our equation to look like this
y=mx+b
we know that m= -3 so we just need to find b
We can start by plugging in the ordered coordinates into our equation
3=(-3)(-2)+b
Solve for b
3=6+b
b= -3
Which means our final equation is
y= -3x-3
Translate the following, "Three times a number is at least that number plus 1 ""
Answer:
3x ≥ x+1
Step-by-step explanation:
Let the number be x.
ATQ,
Three times of a number = 3x
At least means ≥
So,
3x ≥ x+1
So, the required inequality is 3x ≥ x+1.

write the algebraic expression: The difference of 5 times a number and 11 is 17
Answer:
5x - 11 = 17
Step-by-step explanation:
Answer:
5x - 11 = 17
Step-by-step explanation:
Five times a number is 5x when the number is unknown.
The difference between that number and 11 is (difference means subtract)
5x - 11
All of which = 17
5x - 11 = 17

Jayden is driving 390 miles to visit the Gateway Arch in St. Louis. He drives at an average rate of 65 miles per hour. Explain how you can find the amount of time it will take her to get to the arch
Using the relation between velocity, distance and time, it is found that it will take her 6 hours to get to the arch.
What is the relation between velocity, distance and time?Velocity is distance divided by time, that is:
v = d/t.
For this problem, we have that:
She drives 390 miles, hence d = 390.Her velocity is of 65 miles per hour, hence v = 65.We can solve the equation for t to find the time, hence:
65 = 390/t
65t = 390
t = 390/65
t = 6.
It will take her 6 hours to get to the arch.

Your building plan for your restaurant includes one men's and women's restroom. The city inspector lets you kno that you must have at least 400 square feet per bathroom. If your building is a total 4,000 square feet, how many square feet are left for the development other nonbathroom areas?
Answer: 3200 ft^2
Step-by-step explanation:
You have a total area of 4,000 ft^2.
In your plan, you will make two bathrooms (one men's restroom and one women's restroom)
We know that each one of them needs 400ft^2, then the total area needed is two times 400ft^2, or:
2*400ft^2 = 800ft^2
If we subtract this to the total area, we get:
4000ft^2 - 800ft^2 = 3200 ft^2
That is the square feet left for the development of other nonbathroom areas.
