Determine all zeros for the function () = (2 + 2 − 8) ( − 6). Show all work.
The function's two zeros are: x = -1 and x = 6.
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.
To do this, we can set the two factors equal to zero and solve for x:
2x + 2 = 0
x = -1
x - 6 = 0
x = 6
These are the two zeros of the function: x = -1 and x = 6.

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]

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).

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.

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.
y = k x Try it! 1. y is inversely proportional to x. If y = 5 when x = 3, find an equation connecting y and x.

In other words, just because a function takes on a certain value at a particular x-value doesn't mean that the limit of the function at that x-value is equal to that value. To determine the limit of the function, you may need to use different methods such as L'Hopital's Rule or other limit laws.

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.

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

If we consider between mean and median in case of better measure of the center, median is likely to be the better measurement.
The list of values given here is 25, 29, 23, 26, 25, 27, 10, 26, 23, 23, 26.
First we are making or rearranging it in ascending/ descending order.
10, 23, 23, 23, 25, 25, 26, 26, 26, 27, 29.
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.
But median is then also the exact middle number and not influenced by the range of the given data.
Mean and median can be the same in certain cases but when we approximate the measurement of center more than mean, median will likely to give better answer.

Step-by-step explanation:
The colonists thought of King George III as a tyrant, which is evident when looking at the founding documents of the United States and the political parties. 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.
