1. Given the below sequence: -1, -3, -5, -7, . . . (a) What are the next 3 terms? (b) Is this an arithmetic or geometric sequence? (c) Why? (d) What is the 27th term? (Show how to find it and tell me what the 27th term is.)
Answer:
(a) -7 , - 9 , - 11
(b) Arithmetic sequence
(c) There is a common difference of -2
(d) -53
Step-by-step explanation:
(a) To find the next three terms , we must firs check if it is arithmetic sequence or a geometric sequence . For it to be an arithmetic sequence , there must be a common difference :
check :
-3 - (-1) = -5 - (-3) = -7 - (-5) = -2
This means that there is a common difference of -2 , which means it is an arithmetic sequence.
The next 3 terms we are to find are: 5th term , 6th term and 7th term.
[tex]t_{5}[/tex] = a + 4d
[tex]t_{5}[/tex] = - 1 + 4 ( -2 )
[tex]t_{5}[/tex] = -1 - 8
[tex]t_{5}[/tex] = - 9
6th term = a +5d
[tex]t_{6}[/tex] = -1 + 5(-2)
[tex]t_{6}[/tex] = -1 - 10
[tex]t_{6}[/tex] = - 11
[tex]t_{7}[/tex] = a + 6d
[tex]t_{7}[/tex] = -1 + 6 (-2)
[tex]t_{7}[/tex] = -1 - 12
[tex]t_{7}[/tex] = -13
Therefore : the next 3 terms are : -9 , -11 , - 13
(b) it is an arithmetic sequence because there is a common difference which is -2
(c) Because of the existence of common difference
(d) [tex]t_{27}[/tex] = a + 26d
[tex]t_{27}[/tex] = -1 + 26 ( -2 )
[tex]t_{27}[/tex] = -1 - 52

I need help with 2b.
The topic is rational equations and restrictions are 2 and 0.
As my answer I got 0 = 8 but I’m unsure if that’s correct...
Answer:
The answer to your question
a) Values excluded = -2, 0
b) solutions = -2/3, 2
Step-by-step explanation:
Equation
[tex]\frac{4x}{2x + 4} = \frac{x+ 2}{2x}[/tex]
a) x is restricted when the denominators equal zero, so let's get them.
2x + 4 = 0 2x = 0
2x = - 4 x = 0 / 2
x = -4 / 2 x = 0
x = -2
x must be different to -2, 0
b) [tex]\frac{4x}{2x + 4} = \frac{x+ 2}{2x}[/tex]
[tex]\frac{2x}{x + 2} = \frac{x + 2}{2x}[/tex]
4x² = (x + 2)²
4x² = x² + 4x + 4
4x² - x² - 4x - 4 = 0
3x² - 4x - 4 = 0
3x² - 6x + 2x - 4 = 0
3x(x - 2) + 2(x - 2) = 0
(x - 2)(3x + 2) = 0
x₁ - 2 = 0 3x₂ + 2 = 0
x₁ = 2 x₂ = -2/3
Assume that the mean of a normal distribution of IQ scores is 102 and the standard deviation is 15. You have been told that your test score is 1 standard deviation above the mean. What is your IQ test score?
Answer: your IQ test score is 117
Step-by-step explanation:
Assume that the mean of a normal distribution of IQ scores is 102 and the standard deviation is 15.
If you have been told that your test score is 1 standard deviation above the mean, it means that your score would be
102 + 15 = 117
According to the empirical rule, 68% of data falls within the first standard deviation from the mean. This means that 117 falls within 68% of the scores.

Scott and Tom rent a boat at Stow Lake. They start at 10:15 and end at 11:45. The boat rental costs $1.50 for every 15 minutes. How much will they pay?
Answer:they would pay a total amount of $9
Step-by-step explanation:
Scott and Tom rent a boat at Stow Lake. They start at 10:15 and end at 11:45. The number of hours for which they rented the boat would be
11:45 - 10:15 = 1 hour 30 minutes = 1.5 hours.
Converting to minutes, It becomes
60 + 30 = 90 minutes.
The boat rental costs $1.50 for every 15 minutes. Therefore, the total amount of money that they would pay is
90/15 × 1.5 = $9
If y = e^5t is a solution to the differential equation d^2 y/dt^2 - 13 dy/dt + ky = 0, find the value of the constant k and the general form y = Ae^5t + Be^at of the solution to the above equation, (i.e. find a). (Use constants A, B, etc., for any constants in your solution formula.)
Answer:
k = -12/5
A = 125/12
B = -325/12
a = 5
Step-by-step explanation:
y = e^5t
Dy/dt = 5e^5t
d2y/dt2 = 25e^5t
Inputting the values of dy/dt and d2y/dt2 into the equation above, we have:
25e^5t - 13e^5t + 5k(e^5t) = 0
12e^5t + 5k(e^5t) = 0
e^5t(12 + 5k) = 0
12 + 5k = 0
k = -12/5
The equation becomes,
d2y/dt2 - 13dy/dt -12/5y = o
So rearranging the equation,
-5/12d2y/dt2 + 65/12dy/dt + y = 0
y = 5/12(25e^5t) - 65/12(5e^5t)
y = 125/12e^5t - 325/12e^5t
Therefore,
k = -12/5
A = 125/12
B = -325/12
a = 5
The value of the constant k is 40. The general form of the solution is y = A[tex]e^{5t}[/tex] + B[tex]e^{8t}[/tex]
Let's start by recognizing that if y = [tex]e^{5t}[/tex] is a solution to the differential equation d²y/dt² - 13 dy/dt + ky = 0, we need to find the value of the constant k and the general form y = A[tex]e^{5t}[/tex] + B[tex]e^{at}[/tex] of the solution. To do this, we need to determine k and a.
1. First, calculate the first and second derivatives of y = [tex]e^{5t}[/tex]
First derivative: dy/dt = 5[tex]e^{5t}[/tex]Second derivative: d²y/dt² = 25[tex]e^{5t}[/tex]2. Substitute these into the differential equation:
d²y/dt² - 13 dy/dt + ky = 0
3. Substituting, we get:
25[tex]e^{5t}[/tex] - 13(5[tex]e^{5t}[/tex]) + k[tex]e^{5t}[/tex] = 0
25[tex]e^{5t}[/tex] - 65[tex]e^{5t}[/tex] + k[tex]e^{5t}[/tex]= 0
(25 - 65 + k)[tex]e^{5t}[/tex] = 0
(-40 + k)[tex]e^{5t}[/tex] = 0
4. For this to hold true, the following must be true:
k - 40 = 0
Thus:
k = 40
The general solution to the differential equation can be expressed as:y = A[tex]e^{5t}[/tex] + B[tex]e^{at}[/tex]
1. To find a, substitute y = [tex]e^{at}[/tex] into the equation:
d²([tex]e^{at}[/tex])/dt² - 13 d([tex]e^{at}[/tex])/dt + 40[tex]e^{at}[/tex] = 0
We get:
a²[tex]e^{at}[/tex]- 13a[tex]e^{at}[/tex] + 40[tex]e^{at}[/tex]= 0
(a² - 13a + 40)[tex]e^{at}[/tex] = 0
2. The characteristic equation is:
a² - 13a + 40 = 0
3. Solve for a using the quadratic formula:
a = [13 ± √(13² - 4⋅40)] / 2
a = [13 ± √(169 - 160)] / 2
a = [13 ± √9] / 2
a = [13 ± 3] / 2
4. The roots are:
a = 8a = 5Since y = [tex]e^{5t}[/tex] is a solution already, the other root a = 8 is the additional solution. Thus, the general solution to the differential equation is:
y = A[tex]e^{5t}[/tex] + B[tex]e^{8t}[/tex].

Solve the equation by completing the square
-2x^2+x=0
a. {0,-0.5}
b. {1,0}
c. {0.5,0}
d. {0}
Answer:
Option C) [tex]{\{0.5,0}\}[/tex] is correct
The solution to the given equation is [tex]{\{0.5,0}\}[/tex]
Step-by-step explanation:
Given quadratic equation is [tex]-2x^2+x=0[/tex]
To solve the equation by completing the square :
[tex]-2x^2+x=0[/tex]
[tex]-2(x^2-\frac{x}{2})=0[/tex]
[tex]x^2-\frac{x}{2}=0[/tex]
Rewritting the above equation as below :
[tex]x^2-2(x)\frac{1}{4}+\frac{1}{4^2}-\frac{1}{4^2}=0[/tex]
[tex](x-\frac{1}{4})^2-\frac{1}{4^2}=0[/tex]
[tex](x-\frac{1}{4})^2=\frac{1}{4^2}[/tex]
Taking square root on both sides we get
[tex]\sqrt{(x-\frac{1}{4})^2}=\sqrt{\frac{1}{4^2}}[/tex]
[tex](x-\frac{1}{4})=\pm\frac{1}{4}[/tex]
[tex]x=\pm\frac{1}{4}+\frac{1}{4}[/tex]
[tex]x=+\frac{1}{4}+\frac{1}{4}[/tex] and [tex]x=-\frac{1}{4}+\frac{1}{4}[/tex]
[tex]x=\frac{2}{4}[/tex] and [tex]x=0[/tex]
Therefore [tex]x=\frac{1}{2}[/tex] and x=0
[tex]x=0.5[/tex] and x=0
Therefore the solution to the given equation is [tex]{\{0.5,0}\}[/tex]
Option C) [tex]{\{0.5,0}\}[/tex] is correct

You have to find x.
Answer:x = 9.01
Step-by-step explanation:
The given triangle is a right angle triangle.
From the given right angle triangle the hypotenuse of the right angle triangle is 17
With 35 degrees as the reference angle,
x represents the adjacent side of the right angle triangle.
The unlabelled side represents the opposite side of the right angle triangle.
θ = 35 degrees
To determine x, we would apply trigonometric ratio
Cos θ = adjacent side/hypotenuse side. Therefore,
Cos 35 = x/11
x = 11 Cos 35 = 11 × 0.8192
x = 9.01
Answer:
9.01
Step-by-step explanation:
The right angle triangle with a focused angle of degree is easily solved using Trig Ratio that can easily be recalled with this word :
SohCahToa.
What it means is:
If the Opposite side to the focused angle is given and also the hypotenuse is given, we use sine
Cosine if Adjacent and Hypotenuse is given.
Tangent if the opposite and Adjacent is given.
Now, to the question:
The Adjacent and the Hypotenuse is given. Therefore we'll use Cosine.
Therefore:
Cos 35 = x / 11
Cross multiplying:
11 cos 35 = x
11 * 0.8192 = x
Theresfore,
x = 9.01

The Hall family and the Nguyen family each used their sprinklers last summer. The water output rate for the Hall family's sprinkler was 35L per hour. The water output rate for the Nguyen family's sprinkler was 15L per hour. The families used their sprinklers for a combined total of 50 hours, resulting in a total water output of 1050L. How long was each sprinkler used?
Answer:
Nguyen family uses sprinkler for 35 hours while the Hall family uses sprinkler for 15 hours
Step-by-step explanation:
Let h and n be the number of hours that the Hall and Nguyen family individually use their sprinkler for, respectively. Since they use for a combined total of 50 hours, h + n = 50, or h = 50 - n
Also their total water output is 1050 L, we can have the following equation
35h + 15n = 1050
Substitute h = 50 - n and we have
35(50 - n) + 15n = 1050
1750 - 35n + 15n = 1050
35n - 15n = 1750 - 1050
20n = 700
n = 35 hours
h = 50 - n = 50 - 35 = 15 hours
A rectangular box 4 meters long, 3 meters wide and 2 meters tall. On the box is a cat, and the box is floating in water such that half the box is under water. The density of the box is 300 kg/m³. What is the mass of the cat?
Answer:
Mass of the cat = 16800kg
Step-by-step explanation:
The volume of the box = its length * its breath * its height- 4m × 3m × 2m = 24[tex]m^{3}[/tex]
The standard density of water is 1000 Kg/[tex]m^{3}[/tex]
By Archimedes principle, the mass of a body floating body is equivalent to the mass of the volume liquid displaced
in this case we have
Mass of water displaced = Density of the water × Volume of the water displaced = 1000 Kg/[tex]m^{3}[/tex] × 24[tex]m^{3}[/tex] = 24000kg
The mass of the box = Box density × Box volume = 24[tex]m^{3}[/tex] × 300kg/[tex]m^{3}[/tex] = 7200 kg Hence the mass of water displaced = mass of the foating box + mass of th cat
24000kg = mass of cat +7200kg
mass of cat = 24000kg - 7200kg = 16800kg
John is a new college graduate working at his first job. After years of living in an apartment he has decided to purchase a home. He has found a great neighborhood from which he can walk to work. Before buying a home in the area he has decided to collect some data on the homes in this neighborhood. A data set has been compiled that represents a sample of 100 homes in the neighborhood he is considering. The variables included in this data set include:* Value: the current value of the home as determined by the county tax assessor. * Size: the size of the home in square feet. * Year: the year the homes were built. * Basement: does the home have a basement
When analyzing data on homes in a neighborhood, focus on variables like value, size, year built, and basement presence. The sample data set of lawn areas is quantitative and continuous.
Data Analysis Process:
When collecting data on homes in a neighborhood, you can analyze it by looking at variables like value, size, year built, and basement presence. To make sense of the data, you can calculate statistics like the median home value and the variation in values to get a clearer picture of the housing market.
Data Types:
The areas of lawns in square feet sampled from five houses represent quantitative data, specifically continuous data, as they can take on any value within a range without restrictions.

Suppose you add two vectors A and B . What relative direction between them produces the resultant with the greatest magnitude? What is the maximum magnitude?
Answer: The resultant would be the sum and the difference between the vectors.
Step by step explanation: 1. The possible resultant is between the sum of the 2 vectors and the difference between the two vectors.
2. The greatest magnitude is when the vectors lie in the same direction and the sum would be the scalar sum of the two vectors. The angle between the two would be zero degree.
Which angles are coterminal with an angle drawn in standard position measuring 282°?
Select all correct angle measures.
−438∘
−78∘
78°
572°
642°
Answer:
−438°, -78°, 642°
Step-by-step explanation:
Given angle:
282°
To find the co-terminal angles of the given angle.
Solution:
Co-terminal angles are all those angles having same initial sides as well as terminal sides.
To find the positive co-terminal of an angle between 360°-720° we will add the angle to 360°
So, we have: [tex]282\°+360\°=642\°[/tex]
To find the negative co-terminal of an angle between 0° to -360° we add it to -360°
So, we have: [tex]282\°-360\°=-78\°[/tex]
To find the negative co-terminal of an angle between -360° to -720° we add it to -720°
So, we have: [tex]282\°-720\°=-438\°[/tex]
Thus, the co-terminal angles for 282° are:
−438°, -78°, 642°
The correct coterminal angles with 282° are -78° option(2) and 642° option(5). The angles -438°, 78°, and 572° are not coterminal with 282°.
In mathematics, coterminal angles are angles that share the same initial and terminal sides. To find coterminal angles for a given angle, we add or subtract multiples of 360° (a full rotation). For the angle 282°:
1. Subtracting 360°:
⇒ 282° - 360° = -78°
2. Adding 360°:
⇒ 282° + 360° = 642°
Therefore, the angle measures -78° and 642° are coterminal with 282°. The other values, -438°, 78°, and 572°, are not coterminal with 282° as they do not share the same position after full rotations.
In summary, the correct coterminal angles with 282° are -78° and 642°.

Step-by-step explanation:
Let x represent the larger number.
Let y represent the smaller number.
The sum of two numbers is thirty seven. This means that the smaller number would be 37 - x
The translation into a variable expression for the the difference between nine more than twice the larger number and the sum of the smaller number and three would be
2x + 9 - (37 - x + 3)
Opening the parenthesis and putting the constants together, it becomes
2x + 9 - 37 + x - 3
2x + x + 9 - 37 - 3
3x - 31
A manufacturing company with 450 employees begins a new project line and must increase their number of employees by 18% how many total employees does the company have now
Answer: the company now have 531 employees.
Step-by-step explanation:
The initial number of employees that the company had was 450.
The company began a new project line and must increase their number of employees by 18% . it means that the number of new employees that the company employed would be
18/100 × 450 = 0.18 × 450 = 81
Therefore, the total number of employees that the company have now would be
450 + 81 = 531
If x2 + y2 = 25, what is the value of
at the point (4,3)?
O A. -25/27
OB.-7/27
OC. 7/27
D. 3/4
OE. 25/27
Answer:
A. -25/27
Step-by-step explanation:
Given:
The equation is given as:
[tex]x^2+y^2=25[/tex]
To find: [tex]\frac{d^2 y}{dx^2}[/tex] at (4, 3)
Differentiating the above equation with respect to 'x', we get:
[tex]\frac{d}{dx}(x^2+y^2)=\frac{d}{dx}(25)\\\\2x+2yy'=0\\\\x+yy'=0\\\\yy'=-x\\\\y'=\frac{-x}{y}------- (1)[/tex]
Value of [tex]y'[/tex] at (4,3) is given as:
[tex]y'_{(4,3)}=-\dfrac{4}{3}-------- (2)[/tex]
Now, differentiating equation (1) with respect to 'x' again, we get:
[tex]y''=\frac{d}{dx}(\frac{-x}{y})\\\\y''=\frac{y(-1)-(-x)y'}{y^2}\\\\y''=\frac{-y+xy'}{y^2}[/tex]
Now, value of [tex]y''[/tex] at (4,3) is given as by plugging 4 for 'x', 3 for 'y' and [tex]\frac{-4}{3}[/tex] for [tex]y'[/tex]
[tex]y''_{(4,3)}=\frac{-3+(4)(-\frac{4}{3})}{3^2}\\\\y''_{(4,3)}=\frac{-3-\frac{16}{3}}{9}\\\\y''_{(4,3)}=\frac{-9-16}{3}\div 9\\\\y''_{(4,3)}=\frac{-25}{3}\div 9\\\\y''_{(4,3)}=\frac{-25}{3}\times \frac{1}{9}\\\\y''_{(4,3)}=-\frac{25}{27}[/tex]
Therefore, the value of the second derivative at (4, 3) is option (A) which is equal to -25/27.
A _______ variable is a variable that has a single numerical value, determined by chance, for each outcome of a procedure. A ▼ relative key probability random variable is a variable that has a single numerical value, determined by chance, for each outcome of a procedure.
Answer:
random variable
Step-by-step explanation:
Random variable also known as stochastic variables are variables that are used in statistics and probability, The value of a random variable must be determined by chance which remain uncertain and depends on the outcome of a random process or experiment.
Unlike algebra, when random variable is introduced into a mathematical model, it is represented by capital letter and it has a single numerical value.
50 POINT QUESTION!! A person is watching a boat from the top of a lighthouse. The boat is approaching the lighthouse directly. When first noticed, the angle of depression to the boat is 16°23'.

Answer:
That would be the side-side-side (SSS) postulate, which states that if all the sides of a triangle are in a fixed ratio to all the corresponding sides of another triangle, then the two triangles are said to be congruent.
Step-by-step explanation:
Looking at triangles ABC and DEF, we notice that:
[tex]\frac{AB}{DE} = \frac{AC}{DF}=\frac{BC}{EF}[/tex]
since
[tex]\frac{3}{18} = \frac{6}{36}=\frac{7}{42}=\frac{1}{6}[/tex]

The function f(x) = -9x³ + 8x is odd.
Option A is the correct answer.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
A function f(x) is even if f(-x) = f(x).
A function is odd if f(-x) = -f(x).
Using the above definition.
f(x) = -9x³ + 8x
Put x = -x
f(-x) = -9 x (-x³) + 8 x (-x)
f(-x) = 9x³ - 8x
f(-x) = - ( -9x³ + 8x)
f(-x) = -f(x)
This means,
The function is odd.
Thus,
f(x) is odd.
