Answer:
You didn't show the problem so ill just make it to where you can answer yourself
Step-by-step explanation:
so if he uses 3 gallons per 21 miles just divide 3 by 21(yes 3 by 21)
So 0.142 is used per mile
So because you don't show how many miles he traveled just take the number of miles he traveled and times it by 0.142

a survey was conducted to study the relationship between the annual income of a family and the amount of money the family spends on entertainment. data were collected from a random sample of 280 families from a certain metropolitan area.
The scatterplot is the correct answer.
A scatter plot uses dots to represent values for two different numeric variables. The position of each dot on the horizontal and vertical axis indicates values for an individual data point. Scatter plots are used to observe relationships between variables.
The dots in a scatter plot not only report the values of individual data points but also patterns when the data are taken as a whole.
Identification of correlational relationships is common with scatter plots. In these cases, we want to know, if we were given a particular horizontal value, what a good prediction would be for the vertical value.

p(x)=x^3-4x^2-8x please help me solve
Answer: The value of p(x) = (-2,6) or p(x) = (-2,0)
Step-by-step explanation:
Given that,
p(x) = x^3-4x^2-8x
p(x) = [tex]x^{3}[/tex] - [tex]4x^{2}[/tex] - 8x
and replace with '0'.
x^3-4x^2-8x = 0
Now, factorizing equation is,
(x+2) ([tex]x^{2}[/tex] - 6x) = 0
(x+2) = 0
x= -2
Therefore, x = -2
and,
([tex]x^{2}[/tex] -6x) = 0
([tex]x^{2}[/tex] -6x+0) = 0
using quadratic formula = - [b ± √[tex]b^{2}[/tex]-4ac] / 2a
substitute the values,
a = 1, b = -6 , c = 0
p(x) = - [-6 ± √[tex]-6^{2}[/tex]-4.1.0] / 2.1
p(x) = - [-6 ± √36-4.1.0] / 2.1
p(x) = - [-6 ± √36-(0)] / 2.1
p(x) = - [-6 ± √36] / 2.1
p(x) = - [-6 ± 6] / 2
p(x) = [6 ± 6] / 2
p(x) = 3 ± 3
Therefore, p(x) = 3+3 = 6
p(x) = 3-3 = 0
So, that we can say the value of p(x) = (-2,6) or p(x) = (-2,0).

How to find the magnitude of the sum of two vectors
In this question we have the representations of two vectors on a Cartesian plane, of which we must find the magnitude of the two vectors. There are different methods to find it, we decide to use a vectorial method. First, sum the two vectors:
R(x, y) = A(x, y) + B(x, y)
R(x, y) = 7.70 · (cos 27.8°, sin 27.8°) + 16.3 · (- sin 20°, - cos 20°)
R(x, y) = (6.811, 3.591) + (- 5.574, - 15.317)
R(x, y) = (1.237, - 11.726)
Second, use the Pythagorean theorem:
R = √[1.237² + (- 11.726)²]
R ≈ 11.791

Equity capital refers to the funds paid into a business by investors in exchange for common or preferred stock. It can be solved by subtracting the total liabilities from the total assets.
Equity Capital = Total Assets – Total Liabilities
If a company sold 1 million shares of common stock at $10 book value, then its total liabilities is $10 million.
If the stock price then rose to $25 per share on the New York stock exchange, then the total assets is $25 million.

What are the various properties of the logarithm?
Out of several properties of logarithms, some of the main properties are given below:
Product Rule
log (ab) = log a + log b
Change of base
log ₇ x = log x / log 7
Power Rule
log a² = 2 log a
Quotient Rule
log (a / b) = log a - log b
Solving the given equation for x
We are given a logarithmic expression: 3/2 log₂4 - ½ log₂x = 3
Using properties of the logarithm, we have
3/2 log₂4 - ½ log₂x = 3
3/2 (2 log 2 / log 2) - ½ (log x / log 2) = 3
3 - ½ (log x / log 2) = 3
½ (log x / log 2) = 0
log x = 0
log x = log 1

The values of x are 8, -11/2 + ✓243i/2, -11/2 - ✓243i/2
[tex] {(x + 1) }^{3/2} [/tex] - 2 = 25
Adding 2 on both the sides of the equation we get
[tex] {(x + 1) }^{3/2} [/tex] - 2 + 2 = 25 + 2
[tex] {(x + 1) }^{3/2} [/tex] = 27
On squaring both the sides of the equation we get

(x + 1)³ = 729
Now, using the identity (a + b)³ = a³ + b³ + 3ab(a + b), we get
x³ + 1 + 3x² + 3x = 729
x³ + 3x² + 3x - 728 = 0 : Equation 1
By hit and trial method x = 8 is the solution of the equation 1.
Now, by remainder theorem we can write the equation 1 as
x³ + 3x² + 3x - 728 = (x - 8)(x² + 11x + 91) + 0
On solving quadratic equation x² + 11x + 91, we get
x = -b+✓(b² - 4ac)/2a and -b-✓(b² - 4ac)/2a
x = -11+✓(11² - 4×1×91)/2×1 and -11-✓(11² - 4×1×91)/2×1
x = -11+✓(121 - 364)/2 and -11-✓(121 - 364)/2
x = -11+✓(-243)/2 and -11-✓(-243)/2
x = -11/2 + ✓243i/2, -11/2 - ✓243i/2

what relationship must hold for the point to be equidistant from the origin and the xz-plane? make sure that the relationship you state is valid for positive and negative values of a, b, and c
The relationship must hold for the point to be equidistant from the origin and the x z-plane is a^2+b^2+c^2 > b^2.
What is equidistant point:
A point is said to be equidistant from two other points when it is at an equal distance away from both of them. For example, the perpendicular bisector of a line segment is equidistant from both endpoints.
Now,
distance from P(a, b, c) and the Origin (0,0,0)
[tex]\sqrt{(a-0)^2+(b-0)^2+(c-0)^2} =\sqrt{a^2+b^2+c^2}[/tex]
distance from p(a ,b, c) and the x-z plane
[tex]\sqrt{(0-0)^2+(b-0)^2+(0-0)^2} = |b|[/tex]
Here,
P is equidistant from the Origin and the x - z plane
[tex]\sqrt{a^2+b^2+c^2} = |b|[/tex]
[tex]a^{2} +b^2+c^3 = b^2[/tex]
[tex]a^{2} +c^2 = 0[/tex]
Hence a=c=0 ,thus the point P must be of the form (0,b,0) for any b ∈R
Again,
point P far the from the origin than from the x z plane
[tex]\sqrt{a^2+b^2+c^2} > |b|[/tex]
[tex]a^{2} +b^2+c^2 > b^2[/tex]
[tex]a^{2} +c^2 > 0[/tex]
Hence a, c ∈R such that atleast one of the a ,b ,c is non-zero.
Therefore,
(a ,b ,c) for any b∈ R and for a, c ∈ R with atleast one of the a and c is non-zero.

Which angle number represents the linear pair of \angle FHC∠FHC?
The angle number that represents the linear pair of angle FHC is: angle 5.
What is the Linear Pair?The linear pair consists of two adjacent angles that are on a straight line, whose sum will be equal to 180 degrees when added together.
Thus, the two adjacent angles share a common side and a common vertex, and they are supplements of each other. That is, they have a sum of 180 degrees.
Angle 4 represents angle FHC. Angle 5 is adjacent to angle 4, and both lie on a straight line.
Therefore, angle FHC + angle 5 = 180 degrees.
In conclusion, we can state that, the angle number that represents the linear pair of angle FHC is: angle 5.

One example of application of proportions is for percentage problems.
