Based on this data, which state has the greater population density? Move the correct state to the first blank, and move numbers into the remaining blanks to justify the answer. The state with the greater population density is because Illinois Texas 107 231 55,519 261, 232 12,801, 539 27,862, 596
Using it's concept, it is found that the state with greater population density is Illinois.
What is population density?Population density is the number of habitants divided by the area.
Considering the data given, for Illinois, the density is given by:
Di = 12,801,539/55,519 = 230.58 habitants per square mile.
For Texas, the density is given by:
Dt = 27,862,596/261,232 = 106.66 habitans per square mile.
Di > Dt, hence the state with greater population density is Illinois.

Which graph correctly shows point A as the sum of the complex numbers z1 and z2?
A.
B.
C.
D.
The graph which correctly shows the point A as the sum of the complex numbers z₁ and z₂ is graph number 4.
What is complex number?A complex number is the combination of real and imaginary number. In a complex number, real part and imaginary part of the number are written together. For example,
a+bi
Here, (a) is the real part while (b) is the imaginary part.
To add the two complex number on the graph, the addition as transition method is used.
In this one complex number is translated to the tip of the other graph. The resultant of addition is equal to the distance between them.
On the graph 4, the transition method of addition is applied.Thus, the graph which correctly shows the point A as the sum of the complex numbers z₁ and z₂ is graph number 4.

What is the sum of the first five terms in this series?
6 - 6/3 + 6/9 - 6/27 + . . .?
Answer:
4 14/27
Step-by-step explanation:
The first five terms
6
-6/3
6/9
-6/27
+6/81
The first thing to do is change all the fractions denominators to 81.
Sum = 6*81/81 - 6(27)/81 + 6*9/81 - 6*3/81 + 6/81
Now add
Sum = 366/81
Sum = 4 14/27
Sum = 4.5185
Note the first term. It has been multiplied by 6*81/81. The 81 over 81 does not change the value of anything 6 * 81/81 is still 6. It just makes it easier to combine with the other members of the series.

Analyze the graph below to identify the key features of the logarithmic function. (6 points)
The x‐intercept is x = −5, and the graph approaches a vertical asymptote at x = −6.
The x‐intercept is y = −5, and the graph approaches a vertical asymptote at y = −6.
The x‐intercept is x = 5, and the graph approaches a vertical asymptote at x = 6.
The x‐intercept is y = 5, and the graph approaches a vertical asymptote at y = 6.
The x intercept is lies at the midpoint of (-6 and -4
so
x=-5 is the x interceptAnd it's translation of logx
translated equation
y=log(x+6) as log x has x intercept at 1Now the vertical asymptote is at
(x+6)=0x=-6Option A
Answer:
The x‐intercept is x = −5, and the graph approaches a vertical asymptote at x = −6
Step-by-step explanation:
From inspection of the graph:
x-intercept is where the curve intercepts the x-axis → x = -5
y-intercept is where the curve intercepts the y-axis → y ≈ 0.75
An asymptote is a horizontal or vertical line which the curve gets infinitely close to, but never touches.
From the portion of the curve in the graph, it appears that the curve gets very close to but never touches:
the vertical line x = -6the horizontal line x = 1(However, without seeing a large portion of the graph, we cannot be sure, particularly for the horizontal asymptote).
Therefore, from the given solution options:
The x‐intercept is x = −5, and the graph approaches a vertical asymptote at x = −6

The orbit of a planet around the sun is not circular; it is an ellipse with
the Sun at one focus. The aphelion of a planet is the greatest distance
from the sun and the perihelion is its shortest distance. The mean
distance of a planet from the sun is the length of the semimajor axis of
the elliptical orbit. The perihelion of Pluto is 4551 million miles, and the
distance from the center of its elliptical orbit to the sun is 897.5 million
miles. Find the aphelion of Pluto. What is the mean distance of Pluto
from the Sun? Write an equation to represent the orbit of Pluto around
the Sun.
The equation to represent the orbit of Pluto around the Sun will be x²/4659.42 + y²/4566.31 = 1.
How to compute the equation?The distance from the center of the elliptical orbit to the sun is 897.5 million miles. The aphelion will be:
= 5448.5 + 897.5
= 6346 million miles
The equation of ellipse will be:
x²/a² + y²/b² = 1

the measurement of the angle A is 39.17°
Find the value of X. Round to the
nearest tenth.
7.4in
2.4in
x
Answer:
4.4 inches
Step-by-step explanation:
Here, we are interested in calculating the value of x.
Mathematically, a line that comes from the center of the circle and extends to a chord, divides the chord into two equal parts.
This means what we have is a right angled triangle with the radius being the hypotenuse, the half of the length of the chord as the other side of the triangle.
3.7 is half the length of the chord i.e 7.4/2
Thus;
using Pythagoras’ theorem
x^2 = 2.4^2 + 3.7^2
Pythagoras’ posited that the square of the hypotenuse is equal to the sum of the squares of the other two sides of the triangle.
Thus;
x^2 =5.76 + 13.69
x^2 = 19.45
x = √(19.45)
x = 4.41 inches which is 4.4 inches to the nearest tenth

What is the volume of a right circular cylinder with a base radius of 6 feet and a height of 10 feet? 900 cubic meters 120 cubic meters 180 cubic meters 360n cubic meters
Step-by-step explanation:
the volume of a cylinder is
base area × height = pi×r² × height
with r being the radius.
so, we get
pi×6² × 10 = pi×36 + 10 = 360pi =
= 1,130.973355... ft³
now we need to look at the conversion rate between feet and meters :
1 ft = 0.3048 m
1 ft² = 0.3048² m² = 0.09290304 m²
1 f³ = 0.3048³ m³ = 0.028316847... m³
1,130.973355... ft³ = 1,130.973355... × 0.028316847... =
