Answer: 104
Step-by-step explanation:
To put it simply, let's say 100% is 160 dollars. When Christmas arrived, it was sold with a discount of 35%. This means we deduct 35% from 100% which is 65%. We then find 65% of 160 dollars, which is 104.

The hole is (-6,-9) find the rational function which reports this graph
Answer:
Step-by-step explanation:
If there is a hole in the graph at x = -6, that means that there was initially an expression in both the numerator and the denominator that was the same, which is the hole very loosely defined. If the hole is at x = -6, then the factor for that solution is (x + 6). One of those has to be in both the numerator and denominator in order for them to cancel out. This is called a removeable discontinuity. Because the x-intercept is at x = 3, the factor for that zero is (x -3). That has to go in the numerator also. Our equation then for the rational function graphed is
[tex]y=\frac{(x+6)(x-3)}{(x+6)}[/tex] which FOILs to
[tex]y=\frac{x^2+3x-18}{x+6}[/tex]

The values of the terms, a₁, a₂, and a₁₀ of the sequence are;
(a) a₁ = 1, a₂ = 1/2, a₁₀ = 1/10
(b) [tex]\lim\limits_{n\to {\infty}}[/tex] aₙ = 0
What is a mathematical sequence?A sequence is an ordered collection of objects such as numbers in which repetition of the object is possible, and the objects (or numbers) are referred to as the terms of the sequence.
The sequence, [tex]\{a_n\}^\infty_{n = 1}[/tex] with values, aₙ = [tex]\int\limits^{\infty}_1 {\frac{dx}{x^{n + 1}} }[/tex]
(a) a₁ = [tex]\int\limits^{\infty}_1 {\frac{dx}{x^{1 + 1}} } = \int\limits^{\infty}_1 {\frac{dx}{x^2} } = -[\frac{1}{x} ]^{\infty}_1[/tex]
[tex]-[\frac{1}{x} ]^{\infty}_1 = -\frac{1}{\infty} - (-\frac{1}{1} ) = 0 + 1 = 1[/tex]
Therefore; a₁ = 1
a₂ = [tex]\int\limits^{\infty}_1 {\frac{dx}{x^{2 + 1}} } = \int\limits^{\infty}_1 {\frac{dx}{x^3} } = -[\frac{1}{2\cdot x^2} ]^{\infty}_1[/tex]
[tex]-[\frac{1}{2\cdot x} ]^{\infty}_1 = -\frac{1}{\infty} - (-\frac{1}{2 \times 1} ) = 0 + \frac{1}{2} = \frac{1}{2}[/tex]
Therefore; a₂ = 1/2
a₁₀ = [tex]\int\limits^{\infty}_1 {\frac{dx}{x^{10 + 1}} } = \int\limits^{\infty}_1 {\frac{dx}{x^{11}} } = [-\frac{1}{10\cdot x^{10}} ]^{\infty}_1[/tex]
[tex][-\frac{1}{10\cdot x^{10}} ]^{\infty}_1 = -\frac{1}{\infty} - (-\frac{1}{10\times 1} ) = 0 + \frac{1}{10} = \frac{1}{10}[/tex]
Therefore; a₁₀ = 1/10
b) The limit, [tex]\lim \limits_{n\to \infty} a_n[/tex] can be evaluated as follows;
aₙ = [tex]\int\limits^{\infty}_1 {\frac{dx}{x^{n+1} } } \, dx[/tex]
[tex]\int\limits^{\infty}_1 {\frac{dx}{x^{n+1} } } \, dx = [-\frac{1}{n\cdot x^n} ]^{\infty}_1 = -\frac{1}{n\times \infty } - (-\frac{1}{n\times 1^n} )= \frac{1}{n}[/tex]
aₙ = 1/n
Therefore;
[tex]\lim \limits_{n\to \infty} a_n = \frac{1}{\infty}[/tex] = 0
[tex]\lim\limits_{n\to {\infty}} a_n[/tex] = 0

Steve is driving at 35 mi/h when he makes an emergency stop. His brakes lock and his tires leave four skid marks of equal length. The drag factor for the road surface was 0.97 and his brakes were operating at 90% efficiency. How long might the skid marks be to the nearest foot?
The skid marks be to the nearest foot is 913 ft.
The length of the skid marks can be calculated using the formula d = μV2/2gdf, where μ is the coefficient of static friction, V is the velocity, g is the acceleration due to gravity, and df is the drag factor. In this case, the coefficient of static friction can be assumed to be 0.9, the velocity is 35 mi/h, the acceleration due to gravity is 32.2 ft/s2, and the drag factor is 0.97.

Compare Jurgis’s response after his injury to his earlier attitudes. How did his attitude change? Describe your opinion in at least four sentences
Answer:
Step-by-step explanation:
In "The Jungle" by Upton Sinclair, Jurgis is a character who starts out with a positive and optimistic outlook on life. He is full of hope and ambition when he arrives in America with his family, eager to make a better life for himself. However, after he is injured on the job and becomes unable to work, his attitude changes dramatically. He becomes disillusioned and bitter, losing his hope and faith in the American Dream.
In my opinion, Jurgis's response to his injury reflects the harsh realities of life for immigrants and the working class in America during that time. The injury not only physically incapacitates him, but it also robs him of his ability to provide for his family and live out his dreams. The experience shows the extent to which the system is stacked against those in Jurgis's position and serves as a powerful commentary on the injustices and inequalities of the time.

What do you mean by database?A database is a collection of organized data stored and retrieved electronically. It is designed to allow efficient storage, retrieval, manipulation, and management of large amounts of data. Databases can be used to store information such as text, numbers, images, and other media. The data in a database is typically organized into tables, which are made up of rows and columns. Each row represents a single record, and each column represents a field of information within that record. There are many different types of databases, including relational databases, NoSQL databases, and in-memory databases, and they are used in a wide range of applications, such as online retail, finance, healthcare, and more.
The Patient-Sport table is used to connect the patient to the sport they are playing. This allows for multiple sports to be assigned to a single patient. In this way, you can track the sports played by each patient, while still maintaining the relationships between the patient and their data in the other tables.

the cost of first-class postage in 2013 was raised to 46 cents. according to the exponential regression model, what was the predicted cost for 2013? start by noting that 2013 is 63 years since 1950.
The predicted cost of postage for 2013 is 45 cents.
How to determine the predicted cost in 2013We need to use the exponential regression model to predict the cost of postage for the year 2013, given that it was 63 years since 1950.
Let's assume that the cost of postage can be modeled using the exponential function:
C(t) = a * e^(kt)
where:
C(t) is the cost of postage at time ta is the initial cost of postage (in 1950)k is the growth rate of the cost of postage (in decimal form)We can use the two data points we have to solve for a and k:
In 1950, the cost of postage was 3 cents (a = 0.03)In 2013, the cost of postage was 46 cents (C(63) = 0.46)Using the above data points, we can solve for k as follows:
0.03 = a * e^(0 * k)
0.46 = a * e^(63k)
Dividing the second equation by the first equation, we get:
15.333 = e^(63k)
Taking the natural logarithm of both sides, we get:
k = ln(15.333)/63
Evaluate
k = 0.043
Now that we have k, we can use it to predict the cost of postage in 2013:
C(63) = a * e^(63k)
C(63) = 0.03 * e^(63 * 0.043)
C(63) = 0.45
Hence, according to the exponential regression model, the cost is 45 cents.

volume of a sphere = 4/3pir^3 where r is the radius volume of a cone = 1/3pir^2h where r is the radius and h is the height the shape below is made from a cone and a hemisphere work out the volume of the shape give your answer to the nearest integer 8cm 12cm
Answer: To find the volume of the combined shape, we need to find the volume of the cone and the volume of the hemisphere and add them together.
For the cone:
Volume = 1/3 * pi * r^2 * h
Where r is the radius and h is the height. In this case, r = 8 cm and h = 12 cm. So,
Volume = 1/3 * pi * 8^2 * 12 = (1/3) * pi * 64 * 12 = 256 * pi cm^3
For the hemisphere:
Volume = (2/3) * pi * r^3
Where r is the radius. In this case, r = 8 cm. So,
Volume = (2/3) * pi * 8^3 = (2/3) * pi * 512 cm^3
Adding the volumes of the cone and the hemisphere, we have:
Volume = 256 * pi + (2/3) * pi * 512 cm^3 = 256 * pi + 341.3333 * pi cm^3
To the nearest integer, the volume of the combined shape is:
Volume = round(256 * pi + 341.3333 * pi) = round(597.3333 * pi) = 1876 cm^3

How do you find the zeros of a function please give a detailed explanation
There are several ways to find the zeros of the function x^4–18x^2+12x+80. You can graph the equation and see where it crosses the x axis.The graph crosses at x=-4,-2. This means that -4, and -2 are roots, and (x+4) and (x+2) are factors. I like synthetic division the best when it comes to factoring. I teach synthetic division when we get to problems like this, so I will assume that you are familiar with it.First take the coefficients of the equation x^4–18x^2+12x+80 I have to usex^4 +0 x^3 –18x^2+12x+80 : 1 0 -18 12 80. I will use -4 first.If you are not supposed to graph it, then you can use synthetic division. It can take longer because you have to “guess “ at the factors using an educated guess from the factors of =/- p/q . Where p is the last coefficient and q is the first coefficient.In this case we need to find the factors of 80/1 . These are 1,2,4,5,8,10,16,20,40,80. So possible roots are +/- (1,2,4,5,8,10,16,20,40,80). Students usually start with the smaller numbers and work up, So I would try 1 first then 2 etc.Now another way to find the factors is to use 10 as x and to see what the answer is, then try to factor the results. f(x)=x^4–18x^2+12x+80 f(10)=10,000–1800+120+80=8400I can factor 8400 into 100 *6 *14, or (10+0) *(10+0)*(10–4)*(10+4). 0 is not a factor from above, but +/- 4 is. So I could try those two numbers. Looking at the possible roots using 10 as my x, I would need to look at 9,11, 8,12, 0,20 -4,26, etc

The length of BC is 6 inches.
How are radius and tangent to a circle related?There is a theorem in mathematics that:
If there is a circle O with tangent line L intersecting the circle at point A, then the radius OA is perpendicular to the line L.
Given;
Part a;
The length of the secant CD, times its external segment, FC, equals the square of the tangent segment CB;
Mathematically, it can be written as;
RT*ST=TU^2
Part b;
RT*ST=TU^2
TU^2=9*4
TU=6
Therefore, the distance of TU in circle will be 6 inches.
