Answer:
y = 210,000(1.055)^t
Step-by-step explanation:
Initial population: p = 210,000
Annual growth rate: 5.5% = 0.055
Number of years: t
Population in year t: y
y = p(1 + r)^t
y = 210,000(1 + 0.055)^t
y = 210,000(1.055)^t

Answer:
Did you know that Aronson and Carnes-McNaughton's have the perspective on how they study
ancient things from the past.I agree that Aronson will agree with Carnes--McNaughton's statement because they both said the same thing but just in different words. For example in the book "If Stones Could Speak," it will tell what Aronson statement was about when it comes to archaeology and in "Profiles Of Archaeologist," it will tell you the same statement but just in different words. For example it states in the book "If Stones Could Speak," on page 56 "Marc Aronson believes that, “It is about putting aside what you think you know, what has been passed along, and being willing to trust what you yourself see and to test it rigorously.” From this quote the reader will now know what Aronson thinks when it comes to archaeology. In "Profiles Of Archaeologist." On paragraph 19 It states "Being an archaeologist means looking at the world around us in a different perspective. We live in the present as we study the past in order to learn what to do in the future---- on this planet and possibly other. We learn to be humanities while at the same time we practice as scientists. From this quote the reader can understand that both of these statements are similar but they are just reworded. In closing, This why I think that Aronson and Carnes will agree to what to what there statement was.
Step-by-step explanation:
Answer:
Part 1: At eight hours they both charge the same.
Part 2: Flush Plumbing charges the least
Step-by-step explanation:
Part 1:
Flush Plumbing Co Equation: 50 + 10 h (h = hours)
Fire-in-the-hole Plumbing: 90 + 5h (h = hours)
50 + 10h = 90 + 5h
Solve the Equation:
5h = 40
h = 8
Part 2:
Plug in 7:
Flush Plumbing: 50 + 10 x 7 = 50 + 70 = $120
Fire-in-the-hole Plumbing: 90 +5 x 7 = 90 +35 = $125
Flush plumbing chargers the least

Write an equation of the line that passes through the point (-12, 6) and is parallel to the graph of the equation y=-1/6x + 1. Explain your reasoning.
Answer:
y=-1/6x+4
Step-by-step explanation:
In order to pass that point, you have to move the line up 4 points. So you make the 1 at the end to 4.
Help pls with this trigonometry question
would it make more sense to buy two 10 inch pizzas or one 20 inch pizza? Explain your answer in detail.
Answer:
one 20 inch pizza
Step-by-step explanation:
radius of one 10 inch pizza is 10/2 = 5
so area of one 10 inch pizza : [tex]\pi[/tex]× [tex]5^{2}[/tex] = 25 [tex]\pi[/tex]
there are 2 ; 10 inch pizza so 25 [tex]\pi[/tex]⇒[tex]50\pi[/tex]
however 20 inch pizza radius is 10
so
[tex]10^{2}[/tex]×[tex]\pi[/tex] = 100[tex]\pi[/tex]

What is least amount of surface area possible on a rectangular prism with a volume of 64 cubic inches? What are the dimensions of this rectangular prism?
Answer: 64=s3
Step-by-step explanation: V=s3
64=s3
find the cubic root of each side
3√ 64=s4=s
so the side of the cube is 4 cu in.
The surface area of a cube is
SA=nA
where SA
is surface area, n
is the number of faces, and A
is the area of one face.
Te area of one face (A) is s2 so

D. 10x-20
Step-by-step explanation:
The perimeter is just all four sides added together
(3x-2)+(3x-2)+(2x-8)+(2x-8)
add together like terms
3x+3x+2x+2x=10x
-2+-2+-8+-8=-20

A right triangle has legs measuring 5 feet and 12 feet. If the legs of the triangle were doubled, what would be the difference in the original and enlarged perimeters?
Answer:
[tex]30[/tex]
Step-by-step explanation:
1. Approach
First, use the Pythagorean theorem to solve for the hypotenuse of the given right triangle. Then find the perimeter by adding up the values of all the sides. The problem then has the lengths of the legs doubled. When the legs undergo a scaling factor, the hypotenuse and perimeter undergo the same scaling factor. Here, the legs are doubled, hence the hypotenuse and the perimeter are also doubled. Finally, subtract the new perimeter from the original perimeter.
2. Find the original hypotenuse
Remember the Pythagorean theorem states;
[tex]x^{2}+y^{2}=z^{2}[/tex]
Where (a) and (y) are the legs (or the sides adjacent to the right angle), and (z) is the hypotenuse or the side opposite to the right angle.
Substitute in the given value and solve,
[tex](5)^{2}+(12)^{2}=z^{2}\\\\25 + 144 = z^{2}\\\\169=z^{2}\\\\\sqrt{169}=z\\\\13=z[/tex]
3.Find the perimeter of the original triangle
To find the perimeter of a polygon, one must add up the lengths of all the sides.
[tex]5 + 12 + 13\\\\= 30[/tex]
4. Find the new perimeter
In a right triangle, when both legs undergo a scaling factor, the hypotenuse also has the same change, and the perimeter also undergoes the same change. In this case, the length of the legs is doubled, therefore, the hypotenuse and the perimeter are also doubled.
New hypotenuse; [tex]26[/tex]
New perimeter; [tex]60[/tex]
5. Find the difference
Now all that is left is to subtract the new perimeter from the original perimeter;
(New_perimeter) - (original_perimeter)
= [tex]60 - 30[/tex]
= [tex]30[/tex]
