Image of the point (6,-9) after rotation in the cartesian plane of 270 degrees counterclockwise about the origin will be (-9, -6)
As per the question statement, we are supposed to find the image of the point (6,-9) after rotation in the cartesian plane of 270 degrees counterclockwise about the origin.
We should know that a 270° anticlockwise rotation is exactly the same thing as a 90° clockwise rotation.
So the point (x, y) becomes (y, -x)
So the image of the point (6,-9) after rotation in the cartesian plane of 270 degrees counterclockwise about the origin will be (-9, -6)
Cartesian Plane: A Cartesian coordinate system in a plane is a system of coordinates that uniquely identifies each point by a pair of numerical coordinates.

in a large bag of marbles, 20% of them are red. A child chooses 14 marbles from his bag. If the child uses the marbles at random what is a chance that the child gets less than six red marbles?
If the child uses the marbles at random what is the chance that the child gets less than six red marbles is given as 0.9561. See the calculation below.
Note that we are given the following:
p = 20% = 0.20
1 - p = 1 - 0.20 = 0.80
n = 14
Utilizing the binomial formula, we have:
P(X = x) = ((n! / x! (n - x)!) * px * (1 - p)n - x
P(X < 6) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3)+ P(x = 4) + P(x = 5)
Plugging in the value of n, we have:
= ((14! / 0! (14)!) * 0.200 * (0.80)14 + ((14! / 1! (13)!) * 0.201 * (0.80)13 + ((14! / 2! (12)!) * 0.202 * (0.80)12 + ((14! / 3! (11)!) * 0.203 * (0.80)11 + ((14! / 4! (10)!) * 0.204 * (0.80)10 + ((14! / 5! (9)!) * 0.205 * (0.80)9
= 0.9561

What is the focus point of a parabola with this equation?
By interpreting the vertex form of the equation of parabola, the focus of the curve is equal to F(x, y) = (2, 0). (Correct choice: D)
How to determine the coordinates of the focus of a parabola
In this problem we find the equation of a parabola in standard form, which has to be rearranged into its vertex form in order to determine the coordinates of its focus.
The focus of a parabola is a point outside the curve such that the least distance from any point of the parabola and the least distance between that the point on the parabola and directrix are the same.
First, rearrange the polynomial into its vertex form by algebraic handling:
y = (1 / 8) · (x² - 4 · x - 12)
y + (1 / 8) · 16 = (1 / 8) · (x² - 4 · x - 12) + (1 / 8) · 16
y + 2 = (1 / 8) · (x² - 4 · x + 4)
y + 2 = (1 / 8) · (x - 2)²
y + 2 = [1 / (4 · 2)] · (x - 2)²
Second, determine the vertex and the distance between the vertex and the focus:
The parabola has a vertex of (h, k) = (2, - 2) and vertex-to-focus distance of 2.
Third, determine the coordinates of the focus:
F(x, y) = (h, k) + (0, p)
F(x, y) = (2, - 2) + (0, 2)
F(x, y) = (2, 0)
The focus of the parabola is equal to F(x, y) = (2, 0).

After sitting out of a refrigerator for a while, a turkey at room temperature (70°F) is
placed into an oven. The oven temperature is 325°F. Newton's Law of Heating
explains that the temperature of the turkey will increase proportionally to the
difference between the temperature of the turkey and the temperature of the oven, as
given by the formula below:
T=Ta +(To-Ta)e-kt
Ta = the temperature surrounding the object
To the initial temperature of the object
=
t the time in hours
T= the temperature of the object after t hours
k = decay constant
The turkey reaches the temperature of 116°F after 2.5 hours. Using this
information, find the value of k, to the nearest thousandth. Use the resulting
equation to determine the Fahrenheit temperature of the turkey, to the nearest
degree, after 5.5 hours.
The value of k = -0.079
The Fahrenheit temperature of the turkey, to the nearest degree, after 5.5 hours = T(5.5) = 159.865
What is Temperature?
Temperature is a numerical expression of how hot a substance or radiation is. There are three different types of temperature scales: those that are defined in terms of the average, like the SI scale;
Newton's law of cooling states that T=Ta + (To-Ta)e-kt
T = Ta + (To-Ta)e-kt
Ta is the object's ambient temperature.
To equal the starting temperature.
t = the number of hours.
after t hours, temperature equals T.
decay constant is k.
According to the formula,
To = 70 and
Ta = 325,
therefore
(To -Ta) = 70 - 325.
(To -Ta) = -255
T = 325 + (-255 e^kt) or
325 -255e^kt.
After 2.5 hours, the turkey reaches a temperature of 116°F.
In other words,
T(2.5) = 116 F.
Consequently,
116 = 325 - 255e^k2.5
Following that,
116 - 325 = - 255e^2.5k
Now,
-209 = -255e^2.5k
e^2.5k = -209/-255
Using the function 'ln,'
now
ln(e2.5k) = ln(209 / 255)
Then, 2.5k = -0.198929
The value of k is now given by k = -0.198929 / 2.5, which is -0.079571.
The result is k = -0.079.
After 5.5 hours, the temperature is
T(5.5) = 325 - 255e^(-0.079 x 5.5)
Then, = 325 - 255e^(-0.4345)
Now,
= 325 - (165.1350) (165.1350)
T(5.5) = 159.865 is the result.
Consequently, T(5.5) = 159.865 degrees Fahrenheit is the turkey's exact temperature after 5.5 hours.

Suppose this claim is true. If we take a random sample of 20 shipments made by the
company, what's the probability that at least 1 of them arrives late?
Using the binomial distribution, there is a 0.8784 = 87.84% probability that at least 1 of them arrives late.
Binomial distributionThe probability mass function, giving the the probability of x successes is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters of the distribution are given as follows:
n is the number of trials of the experiment.p is the probability of a success on a single trial of the experiment.In the context of this problem, of 20% shipments with 90% on time, the parameters are:

Fråga 5 20 poäng A farmer wants to plant a small rectangular plot of ornamental blue corn. He has enough fencing material to enclose a space with a perimeter of 144 feet. He wants to know the dimensions of the largest rectangle that can be enclosed with 144 feet of fence. To help find them, he graphed the following equation. Area = x (72 - x) What are the dimensions of the largest area the farmer can enclose with 144 feet of fence?
The maximum dimensions is a square of sides 36 ft by 36 ft;
The maximum area is 1,296 ft^2
Here, we want to know the diemensions of the largest area the farmer can enclose within the perimeter
Mathematically, the greatest dimension that can maximize the area of the plot is the shape being a square
In other words, we need the diemnsions of both sides to be equal so as to get the area
If the dimensions are equal, we can say the length and width are represented by x
The length is thus as follows;
[tex]\begin{gathered} 4\text{ }\times\text{ x = 144} \\ 4x\text{ = 144} \\ \text{ x = 144/4} \\ x\text{ = 36 ft} \end{gathered}[/tex]The greatest possible or the maximum area is thus;

Ratios that can be streamlined or decreased to the same value are said to be equivalent. In other words, if one ratio can be written as a multiple of the other, then they are said to be equivalent. The ratios 1:2 and 4:8, 3:5 and 12:20, 9:4 and 18:8, and others are some examples of analogous ratios. To put it another way, two ratios are said to be equivalent if one of them can be written as the multiple of the other. Therefore, we must multiply the two values (antecedent and consequent) by the same number in order to obtain the equivalent ratio of another ratio. This approach is comparable to the approach for determining equivalent fractions.

what are the coordinates of Y if 5,12 is 1/3 of the way from X to Y
The coordinates of the point Y at the other endpoint is 41
How to determine the coordinates of the point Y?From the question, the given parameters are
Point X = 5The location of the point between X and Y = 12Proportion = 1/3Because there is not y coordinates in the coordinates, we can make use of only the x coordinate
So, we have the following equation
Point = Proportion * (Y - X)
Substitute the known values in the above equation
So, we have the following equation
12 = 1/3 * (Y - 5)
Multiply through the equation by 3
So, we have the following equation
36 = Y - 5
Add 5 to both sides of the equation
So, we have the following equation
Y = 41
