A function f is said to have a removable discontinuity at a if:
1. f is either not defined or not continuous at a.
2. f(a) could either be defined or redefined so that the new function is continuous at a.
Let f(x)=2x²+4x-6/x-1
Show that f has a removable discontinuity at 1 and determine the value for f(1) that would make f continuous at 1.Need to redefine f(1)=
The discontinuity of the function is removed and the value of the function at 1 after removing the discontinuity is 8.
What is meant by a discontinuity in a function?
In algebra, a discontinuous function is one that has a point at which the function is not defined, at which the left-hand limit and right-hand limit are equal but not equal to the value of the function at that point, or at which the limit of the function does not exist. If a function in algebra is not continuous, it is referred to as a discontinuous function. A discontinuous function has a discontinuous curve, just like a continuous function does.
Given f(x) = 2x²+4x-6 / (x-1)
This function has a discontinuity at 1 because when we substitute x =1, the denominator becomes 0 and the function becomes undefined.
But this discontinuity is removable and can be done as shown:
We can factorize the numerator as below:
2x²+4x-6 = 2x²+6x - 2x -6 = 2x(x+3) -2(x+3) = (2x - 2)(x+3) = 2(x-1)(x+3)
Now when we substitute the factorized form of the numerator in the function. Then,
f(x) = 2(x-1)(x+3) / (x-1)
(x-1) can be cancelled from both the numerator and denominator. So the discontinuity is removed.
f(x) = 2(x+3)
Now f(1) = 2 * (1+3) = 8
Now the function is continuous at 1.
Therefore the value of the function at 1 after removing the discontinuity is 8.

Is the theoretical probability that the coin lands head up all three times is the same value as the theoretical probability that the coin lands tails up all three times? Explain.
Yes, the theoretical probability of getting three heads in a row is the same as the theoretical probability of getting three tails in a row. This is because each flip of a fair coin is an independent event and has an equal chance of landing on either heads or tails.
What is theoretical probability about?The probability of getting heads on a single coin flip is 0.5 (or 1/2), and the same is true for getting tails on a single coin flip. The probability of getting three heads in a row is calculated by multiplying the probability of getting heads on each of the three flips together, which is"
(1/2) x (1/2) x (1/2) = 1/8.
Similarly, the probability of getting three tails in a row is also:
(1/2) x (1/2) x (1/2) = 1/8.
Therefore, the theoretical probability of getting three heads in a row is the same as the theoretical probability of getting three tails in a row, both of which are 1/8.

is it possible to have a function f defined on [ 2 , 4 ] and meets the given conditions? f is continuous on [ 2 ,4 ] and the range of f is an unbounded interval.
No, it is not possible to have a function f defined on [2,4] that is continuous and has an unbounded range. This is because of the Extreme Value Theorem, which states that a continuous function on a closed interval must have a maximum and minimum value within that interval. If the range of f is unbounded, then there is no maximum or minimum value, which contradicts the Extreme Value Theorem. Therefore, it is not possible to have such a function.
If we modify the condition to allow for an unbounded range in only one direction (either unbounded from above or unbounded from below), then it is possible to have a function that is continuous on [2,4] with an unbounded range.
For example, consider the function f(x) = 1/(x-4) defined on the interval [2,4]. This function is continuous on [2,4] and has an unbounded range in the negative direction, as f(x) approaches negative infinity as x approaches 4 from the left.
Another example is the function g(x) = x^2 defined on the interval [2,4]. This function is continuous on [2,4] and has an unbounded range in the positive direction, as g(x) approaches infinity as x approaches 4 from the right.
So, it is possible to have a continuous function on [2,4] with an unbounded range in one direction, but not in both directions simultaneously.

There are 2 green marbles, 7 blue marbles, 3 white marbles, and 4 purple marbles in a bag. Once a marble is drawn, it is NOT replaced. Find the probability of white then purple P(white, purple). Write your answer as a simplified fraction.
P(a purple marble then a white marble) is 6/105 ⇒ 1st answer
Step-by-step explanation:* Lets explain how to solve the problem
- There are 2 green marbles
- There are 7 blue marbles
- There are 3 white marbles
- There are 4 purple marbles
- Once a marble is drawn, it is NOT replaced
- We need to find P(a purple marble then a white marble)
* At first lets find the total number of marbles by adding all color
∵ There are 2 green , 4 purple , 3 white and 7 blue
∴ The total number of marbles = 2 + 4 + 3 + 7 = 16
∴ There are 16 marbles in the bag
∵ Probability = number of events/number of all outcomes
∵ There are 4 purple marbles
∴ The probability of chosen a purple marble is P(purple) = 4/15
∵ Once a marble is drawn, it is NOT replaced
∴ The total number of marbles = 15 - 1 = 14 marbles
∵ The number of white marbles is 3
∴ The probability of chosen a white marble is P(white) = 3/14
∵ P(a purple marble then a white marble) = P(purple) . P(white)
∵ P(purple) = 4/15
∵ P(white) = 3/14
∴ P(a purple marble then a white marble) = (4/15)(3/14) = 6/105
* P(a purple marble then a white marble) is 6/105

the standard matrix of T. T: R2→R2 is [ 0 1 ]
[ 1 0]
We must locate the pictures of the standard basis vectors of R2 under T and translate those images into columns of a 2x2 matrix in order to get the standard matrix of T.
Let's start by thinking about the reflection along the line x2 - x1. The point (x1, x2) is mapped to the point via this reflection (x2, x1).
We apply T to the first standard basis vector, e1 = (1,0), to determine its image:
T(e1) = (0,1) (0,1)
We also use T: to determine the image of the second standard basis vector, e2 = (0,1).
T(e2) = (1,0) (1,0)
Hence, (0,1) and (1,0) are the images of the standard basis vectors, These photos can now be expressed as columns in a matrix:

Let G be the number of general seats sold.
Let R be the number of reserved seats sold.
The total number of seats sold is G + R = 1139
Since general seats costs $2 each, 2G is the total receipts from general tickets sales.
Since reserve seats costs $3.50 each, 3.5R is the total receipts from reserved ticket sales.

Differentiate y=x4 -x
Answer:
Step-by-step explanation:
To differentiate the function y = x^4 - x, we will use the power rule of differentiation. The power rule states that if f(x) = x^n, then the derivative of f(x) is f'(x) = nx^(n-1).
So, for y = x^4 - x, we can find the derivative as follows:
y' = 4x^3 - 1
So, the derivative of the function y = x^4 - x is y' = 4x^3 - 1.
4(x - 1)(3x - 1) = 0 answer?
Answer:
[tex]x = 1 \ \ \ \text{OR} \ \ \ x = \dfrac{1}{3}[/tex]
Step-by-step explanation:
First, multiply out the set of parentheses and simplify the resulting quadratic expression.
[tex]4(x - 1)(3x - 1) = 0[/tex]
[tex]4(3x^2-x-3x+1) = 0[/tex]
[tex]4(3x^2-4x+1) = 0[/tex]
Then, factor out a 3 from the parentheses to get rid of the coefficient on the quadratic's first term.
[tex]4(3(x^2-\dfrac{4}{3}x+\dfrac{1}{3})) = 0[/tex]
[tex]12(x^2-\dfrac{4}{3}x+\dfrac{1}{3}) = 0[/tex]
Finally, complete the square.
[tex]12\left(x^2-\dfrac{4}{3}x + \left(\dfrac{-\dfrac{4}{3}}{2}\right)^2\right) = 12\left(-\dfrac{1}{3}\right) + 12\left(\dfrac{-\dfrac{4}{3}}{2}\right)^2[/tex]
[tex]12\left(x^2-\dfrac{4}{3}x + \dfrac{4}{9}\right) = -4 + \dfrac{16}{3}[/tex]
[tex]12\left(x - \dfrac{2}{3}\right)^2 = \dfrac{4}{3}[/tex]
[tex]\left(x - \dfrac{2}{3}\right)^2 = \dfrac{1}{9}[/tex]
↓ take the square root of both sides
[tex]x - \dfrac{2}{3}\right = \pm \sqrt{\dfrac{1}{9}}[/tex]
[tex]x = \dfrac{2}{3} \pm \sqrt{\dfrac{1}{9}}[/tex]
[tex]x = \dfrac{2}{3} \pm\dfrac{1}{3}[/tex]
↓ split into two equations
[tex]x = \dfrac{2}{3} + \dfrac{1}{3} \ \ \ \text{OR} \ \ \ x = \dfrac{2}{3} - \dfrac{1}{3}[/tex]

What is function?In mathematics, a function is a set of ordered pairs (input, output), where each input is associated with exactly one output. The input is commonly referred to as the independent variable, and the output is referred to as the dependent variable. A function can be represented algebraically, graphically, or verbally. Algebraically, a function is often represented by an equation that defines the relationship between the independent variable and the dependent variable. For example, the equation y = 2x + 1 defines a linear function, where x is the independent variable and y is the dependent variable.
Here,
The zeros of a function are the values of the independent variable for which the function equals zero. To determine all zeros for the function f(x) = (2x + 2)(x - 6), we need to find the solutions to the equation f(x) = 0.

Mean will be the average of the given set.
Median will be the exact middle number or the average of the two middle entries.
Mean = 23.9
Median = 25
If we consider the range of data and how it is distributed, you can see it ranges from 10 to 29.
But the problem is that, after 10, the second least value is 23 and rest of the values are nearer also.
There is a clear gap between the values of other data points and the first data entry 10.
As mean is the average of every data, this 10 can directly influence the value of mean and cannot gave us an approximation of center.
Imagine that if the last entry is somewhat very big number, then the mean will surely slant to the higher number as it is the sum average of the given set of data.

The Constitution created separation of powers so nobody would be able to become a tyrant or dictator. There are checks and balances to keep people from gaining too much power and overtaking the government. When looking into the political parties later on, there were the Anti-federalists, who did not want a strong central government because they did not want another King George, who they just got out of a war with.

The density of this a box of tissues is 1 g/cm3. The mass of the object is 728 grams.
The length is 20.8cm, the width is 7cm, what is the height?
The formula for the volume of a rectangular box is V = l × w × h, where l is the length, w is the width, and h is the height. Since the density is given as 1 g/cm³, the mass of the object is equal to its volume in cubic centimeters (cc):
mass = volume × density
728 g = V × 1 g/cm³
V = 728 cm³
We are given the length and width of the box, so we can substitute these values into the formula for volume:
V = l × w × h
728 cm³ = 20.8 cm × 7 cm × h
Simplifying the right-hand side:
728 cm³ = 145.6 cm² × h
Dividing both sides by 145.6 cm²:
h = 728 cm³ ÷ 145.6 cm²
h = 5 cm
Therefore, the height of the box is 5 cm.
1. Exercise 4E Write the following scales in the form of 1:n, where n is a whole number. (a) 5 cm represents 4 m (c) 5 cm represents 4 km (d) 4 cm represents 5 km
The scales in the ratio of 1 : n are:
a) 1 : 80
c) 1 : 80000
d) 1 : 100000
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
a)
5 cm and 4 m
1 m = 100 cm
So,
4 m = 4 x 100 cm
4 m = 400 cm
Ratio.
= 5 cm : 4 m
= 5 cm : 400 cm
= 1 : 80
c)
5 cm and 4 km
1 km = 100000 cm
So,
4 km = 400000 cm
Ratio.
= 5 cm : 400000 cm
= 1 : 80000
d)
4 cm and 5 km
1 km = 100000 cm
So,
5 km = 500000 cm
Ratio.
= 5 cm : 500000 cm
= 1 : 100000
Thus,
The scales in the ratio of 1 : n are:
1 : 80
1 : 80000
1 : 100000
