Answer:
B) 0.42
Step-by-step explanation:
population density=number of people/square units
we plug in 2,100 for the first one but we don't know the second one for that we need the area which is A=π[tex]r^{2}[/tex] so the radius is 40 millimeters so [tex]40^{2}[/tex] =1600 1600*π=5024
2,100/5024=0.417 round it up and it is 0.42
so B) 0.42 is the answer

The area of the hexagon is the sum of triangles in it. Then the area of the hexagon is 672 square cm.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
A regular hexagon has an apothem measuring 14 cm and an approximate perimeter of 96 cm.
We know that the area of the hexagon is the sum of triangles in it.
Area of hexagon = 6 × area of a triangle
The length of a side of the hexagon will be
6 × Side = 96
Side = 16
The area of the triangle will be
[tex]\rm Area \ of \ triangle = \dfrac{1}{2} *14*16\\ \\Area \ of \ triangle = 112 \ cm^2[/tex]
Then the area of the hexagon will be
Area of hexagon = 6 × 112
Area of hexagon = 672
The area of the hexagon is 672 square cm.

Oil flows back and forth between a small and large tank. When oil is moving into the large tank, the flow rate is positive. When oil is moving into the small tank, the flow rate is negative. The large tank begins with 600 gallons of oil. The flow rate is recorded as –4 gallons per minute. After a period of 32 minutes, how much oil has been moved and to which tank?
Flow is given as, F = - 4 gallon per minute into small tank.
( Since, flow is negative )
Volume of oil in large tank, V = 600 gallons.
Now,
Volume of oil has been moved :
[tex]v = F \times t\\\\v = -4 \ gallons/min \times\ 32\ min\\\\ v = -128\ gallons[/tex]
Therefore, 128 gallons of oil has been moved to small tank.
Hence, this is the required solution.
Answer:
128 gallons, into the small tank. I think its the second option for the last box, not 100 percent sure but i did the question so yea :D

Step-by-step explanation:
In India, the first step towards criminal proceeding is an investigation by the police. The investigation is the exclusive domain of the police and can not be curtailed in normal circumstances. The main purpose of an investigation is the identification of the offender so as to serve him with punishment for the crime done by him in accordance with the provisions contained under law. According to Section 156 of the Code of Criminal Procedure, the police have unfettered powers to investigate into a cognizable offence. The term cognizable offence is any act or omission committed by a person under any law in force which is punishable and is considered to be a crime. The police have the authority to arrest any person who has committed a cognizable offence. Beside Criminal investigation, there are other types of investigations which become the part of the life of an investigator. Some of the types of investigation are as follows:
Civil investigation: These are the investigations which are carried on during the civil suits in which violation of law is generally not included and the question of money or property is to be settled;
Negligence investigation: These types of investigations are conducted either by the plaintiff’s counsel to prove the liability of the defendant or by the defendant’s attorney to refute the claims of the plaintiff. It is accomplished by the use of surveillance, interviewing the witnesses;
Corporate investigation: In Corporate investigations the investigator monitors the business of the company and also provides the information about the fraud within or outside the company;
General investigation: It is like an umbrella term including a great variety of investigative activities. These activities may be conducted for different purposes like the determination of the location of witnesses, dishonest employees, fraud etc.

Question: You are playing your favorite video game, Hero's Quest. In the game, you can complete missions to earn experience points. You may complete a mission as many times as you would like, but each time you do, you only receive 80% as much experience as the previous time. The first time that you complete Mission A, you earn 1000 experience, points. The second time you complete it, you earn 800 experience points. How many times can you complete the mission before you earn less than 400 points? Explain your answer
Using a geometric sequence, it is found that you can complete the mission 5 times before you earn less than 400 points.
What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given by:
[tex]a_n = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.
In this problem, the amount of points after n times is a geometric sequence with [tex]a_1 = 1000, q = 0.8[/tex], hence the equation is:
[tex]a_n = 1000(0.8)^{n-1}[/tex]
You will earn less than 400 points when:
[tex]a_n < 400[/tex]
Hence:
[tex]1000(0.8)^{n-1} < 400[/tex]
[tex](0.8)^{n-1} < 0.4[/tex]
[tex]\frac{0.8^n}{0.8} < 0.4[/tex]
[tex]0.8^n < 0.32[/tex]
[tex]\log{0.8^n} < \log{0.32}[/tex]
[tex]n > \frac{\log{0.32}}{\log{0.8}}[/tex]
[tex]n > 5.1[/tex]
You can complete the mission 5 times before you earn less than 400 points.

Graph of all 4 functions attached
Black one is the 4th oneAnswer:
[tex]y=\sqrt[3]{x+3}+3[/tex]
Step-by-step explanation:
From inspection, we can see that the base graph is [tex]y=\sqrt[3]{x}[/tex]
(As the graph of [tex]y=\sqrt{x}[/tex] is only valid for x ≥ 0 ⇒ y ≥ 0)
The center of [tex]y=\sqrt[3]{x}[/tex] goes through the origin (0, 0)
From inspection, we can see that the center of the curve is now at (-3, 3)
So the graphed function has been shifted 3 units left:
[tex]\implies y=\sqrt[3]{x+3}[/tex]
and shifted 3 units up:
[tex]\implies y=\sqrt[3]{x+3}+3[/tex]

A sum of 300 pounds into the ratio of 1:2:2. How much is the smallest share?
Answer:
60
Step-by-step explanation:
Summing the ratios gives 1+2+2=5
300/5 = 60
(1 x 60) + (2 x 60) + (2 x 60)
(60) + (120) + (120) = 300
Hence the least share is 60
The other two shares are equal which is 120

Answer:
a = -√3/3
b = 2√3/3
Step-by-step explanation:
Finding the slope of the tangent at C by finding the derivative:
x^2 + y^2 = 1
2x + 2y y' = 0
2y y' = -2x
y' = -2x / 2y = -x/y
So the slope = - 1/2 / √3/2
= -1/2 * 2/√3
= -1/√3
= -√3/3
Using the point-slope form of a straight line
y - y1 = m(x - x1)
y - √3/2 = -√3/3(x - 1/2)
y - √3/2 = -√3/3 x +√3/6
y = -√3/3 x + √3/6 +√3/2
y = -√3/3 x + 4√3/6
y = -√3/3x + 2√3/3
