Answer:
Common difference = x - 2.
Step-by-step explanation:
Differences:
-2x - 9 - (-3x - 7)
= -2x - 9 + 3x + 7
= x - 2
-x - 11 - (-2x - 9)
= - x - 11 +2x + 9
= x - 2
So, it is Arithmetic.
Answer:
Arithmetic sequence.
Common difference = -x - 11
Step-by-step explanation:
This is an arithmetic sequence.
-3x - 7, -2x - 9, -x - 11, ...
Find the common difference.
Common difference =second term - first term.
= -2x - 9 - (-3x - 7)
= -2x - 9 + 3x +7
= -2x + 3x - 9 + 7 {Combine like terms}
= x - 2
If we add the common difference to the second term, we will get the third term.
Third term = second term + common difference
= -2x - 9 + x - 2
= -2x + x - 9 - 2
= -x - 11.
Hence this is an arithmetic sequence.
Solve for r
V= 4/3 pi r^2h
Answer:
r = [tex]\sqrt{\frac{3V}{4\pi h} }[/tex]
Step-by-step explanation:
V = [tex]\frac{4}{3}[/tex] πr²h ( multiply both sides by 3 to clear the fraction )
3V = 4πr²h ( isolate r² by dividing both sides by 4πh )
[tex]\frac{3V}{4\pi h}[/tex] = r² ( take square root of both sides )
[tex]\sqrt{\frac{3V}{4\pi h} }[/tex] = r
Charlie's phone number is 555-3703. If he places each of the digits in a bowl and randomly selects one number at a time without replacement, what is the probability that lie will choose his phone number?
The probability that he will choose his phone number is 1/420.
we are given the phone number 555- 3703, which contains 7 digits : 3 5s, 2 3s, 1 0s, and 1 7s,
The formula for the probability of an event is:
no.of possible cases / total number of cases.
For the final result, we need to find the individual digits' probabilities and multiply them.
So, the probability of first digits: 3/7
the probability of Second digits: 2/6
the probability of third digits: 1/5
the probability of fourth digits: 2/4
the probability of fifth digits: 1/3
the probability of Sixth digits: 1/2
Therefore the probability of picking up his phone number is
= 3/7 * 2/6 *1/5 * 2/4 * 1/3 *1/2
= 1/420

In linear equation, the intersection at coordinate (9, 315).
What in mathematics is a linear equation?
There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.Gym one:
f(x) =80 x + 25
Gym two:
g(x) = 35x (+ 0 [since there was no joining fee])
The first month is easy.
Gym one's cost is just the joining fee plus the one month of membership fee. Or...
105 = 80(1) + 25
Gym two's cost is just that first month's membership fee. Or...
35 = 35(1) + 0
then second month
[f(x) = 185 = 80(2)+25
g(x) = 70 = 35(2)],
then a tenth month [
f(x) = 825 = 80(10) + 25;
g(x) = 350 = 35(10)]

A square is inscribed in a circle. What is the ratio of the area of the circle to the area of the square?
The side of the square inscribed in a square be a units then the required ratio is π : 2.
What is an inscribed square?
A square is inscribed in a circle or a polygon if its four vertices are on the circle's circumference or the polygon's sides.
Inscribed in the circle is a square that fits snugly inside a circle. The square's corners will touch but not intersect the circle's boundary, and the diagonal of the square will equal the diameter of the circle. Furthermore, as with any square's diagonal, it equals the hypotenuse of a 45°-45°-90° triangle.
Let the side of the square inscribed in a square be a units.
Hence, the required ratio is 2 : 1.
Let ABCD be a square inscribed in a circle of radius 'r'.
Now, the diameter of the circle is the diagonal of the square.
Therefore, BD = 2r.
In △BDC, using Pythagoras theorem
[tex]BC^2+CD^2=BD^2[/tex]
⇒ [tex]a^2+a^2=(2r)^2[/tex]
⇒ [tex]2a^2=4r^2[/tex]
⇒ [tex]a^2=2r^2[/tex]
Area of square=[tex]2r^2[/tex]
Area of circle =[tex]$$\pi r^2[/tex]
Required ration = [tex]$\pi r^2:2r^2[/tex] = π : 2
Therefore, the required ration is π : 2.

What is a solution's equilibrium?
Differential equations can have solutions called equilibrium solutions when the derivative along those solutions equals zero. In other words, at that solution, the slope is a horizontal line.
Consider the following potentials:
U(x) = [tex]x^{4}[/tex]
U(x ) = [tex]x^{6 } - x^{4}[/tex]
U( x ) = [tex]x^{4} + x^{3}[/tex]
All three of these potentials have an equilibrium point at x=0. All three of these potentials are such that the second derivative of U(x) at this equilibrium point is zero.
However, you should convince yourself (perhaps by plotting these potentials) that in the first case the equilibrium is stable, in the second case it is unstable, and in the third case the equilibrium is, as you put it, "stable in one direction but unstable in the other".
The second derivative is zero tells us nothing about stability.

An executive invest $21,000, some at 8% and the rest at 5% annual interest. if he receives an annual return of $1,470, how much is invested at each rate
Using algebraic expression and equation, an executive assistant invested $14,000 and $7,000 at the rate of 8% and 5% annual interest, respectively.
An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".
Given that an executive invest a total of $21,000, we can express this as:
x + y = 21,000 ⇒ x = 21,000 - y (equation 1)
where x = amount invested at 8% annual interest
y = amount invested at 5% annual interest
If the annual return is $1,470, then the sum of the product of the rate and the amount is equal to the annual return.
8%x + 5%y = $1,470
0.08x + 0.05y = 1,470 (equation 2)
Substitute equation 1 to equation 2 and solve for y.
0.08(21,000 - y) + 0.05y = 1,470
1680 - 0.08y + 0.05y = 1470
-0.03y = -210
y = 7000
amount invested at 5% annual interest = $7000
x = 21,000 - y
x = 21,000 - 7000
x = 14,000
amount invested at 8% annual interest = $14000

Asking people at an international airport can be thought of as bias because there might a lot of people at the airport who are old and who like to travel.
Asking people whether they’d prefer Italy or France could be bias because what if the people are Italian? Then they’d obviously choose Italy. Or maybe they’re French and they’ve lived in France and been to France too many times and they’d rather visit Italy.
If 86% of people asked took a French course, you can assume they want to learn French (obviously) and that they probably want to learn French so they can visit and be able to communicate with others in France.

The interior angle measure of a regular polygon is given. Identify the polygon.
135
The regular polygon with an interior angle of measure 135 is an octagon.
A regular polygon is a polygon that has equal side lengths and equal interior angle measures.
Interior angle of a polygon is the angle inside it that is formed by two adjacent sides. The number of interior angles formed inside a polygon is the same as the number of its sides. Meanwhile, the sum of all the interior angles of any polygon is constant to that polygon and depends on the number of sides.
sum = 180(n - 2)
Let n = number of sides of the polygon = number of interior angles
sum = measure of interior angle x n
Using the formula,
sum = 180(n - 2)
135n = 180(n - 2)
135n = 180n - 360
180n - 135n = 360
45n = 360
n = 8
If the polygon has 8 sides and 8 interior angles, then the regular polygon is an octagon.
