m ∠6 = 55°
Step-by-step explanation:
Angles 2 and 6 are corresponding angles and equal
m ∠2 + 125° = 180° since they are linear supplementary angles
m ∠2 = 180 - 125 = 55°
Since m ∠2 = m ∠6
m ∠6 is also 55°

The polar equation r = 7 sin (2theta) graphs as a rose.What is the length of the petals of this rose?Enter your answer in the box.
Answers
This problem is about a polar equation. It's important to know that polar coordinates depend on two variables, the angle of the vector and its distance.
[tex](r,\theta)[/tex]Where r represents the distance and theta represents the angles.
In this case, the angle is 20°, according to the problem.
So, first, we need to graph this equation in the polar system, to then measure the length of the petals
[tex]r=7\sin (2\theta)[/tex]The graph of this equation is shown in the image attached below.
In the image above, you can observe the polar equation graphed, with the coordinated system behind, this will allow us to find the length of each (which are symmetrical). You can observe that the petal on the third quadrant is at (-5,-5).
Now, we use the following formula to find the distance
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]Replacing the points, we have
[tex]d=\sqrt{(-5)^2+(-5)^2}=\sqrt{25+25}=\sqrt{2(25)}=5\sqrt{2}\approx7.07[/tex]Therefore, the length of each petal is 7.07 units, approximately.A botanist has determined that there is a relationship between how much a certain plant grows and how much water it receives.

I need help with question c only
Answers
Answer:
y = 2
Step-by-step explanation:
A horizontal asymptote is a horizontal line that the graph of a function approaches as x approaches ±∞.
Mathematically we write this as
[tex]f(x) \rightarrow a \text{ as } x \rightarrow \infty \text{ or } x \rightarrow -\infty[/tex]
A vertical asymptote at some constant a is where the function approaches ±∞.
Mathematically
[tex]f(x) \rightarrow \infty \text { or } f(x) \rightarrow -\infty \text{ as } x \rightarrow a[/tex]
The given function y = 2ˣ + 2 is an exponential function and exponential functions do not have a vertical asymptote
The horizontal asymptote can be found by determining what the function limit is as [tex]x \rightarrow \pm \infty[/tex]
As [tex]x \rightarrow +\infty[/tex] the function [tex]\rightarrow \infty[/tex]
As [tex]x \rightarrow -\infty[/tex] , [tex]2^x \rightarrow 0\\\\\\2^x + 2 \rightarrow 2\\\\[/tex]
So the equation for the horizontal asymptote is y = 2
The graph shows that at y = 2, the function is parallel to the line but does not touch the line

Answers
The difference of the two matrices [3 -8] and [4 -5 -6] is an impossible operation to execute as per arithmetic rules.
As per the question statement, we are provided with two matrices, [3 -8] and [4 -5 -6].
We are either required to calculate the difference of the above mentioned matrices, or else, determine if the operation is impossible to perform.
To solve this question, we need to know about the order of a matrix first.
The Order of a matrix is the representation of the number of rows and columns of that matrix, in the form of "m×n" and read as (m by n), where "m" is the number of rows in that matrix while "n" is the number of columns. It also tells us about the total number of entries or elements in a particular matrix, which we can calculate by performing the multiplication of it's order, i.e., (m * n)Now, one basic rule of matrix subtraction is that, matrices having the same order can only be subtracted from each other.Here, in our case, matrix [3 -8] is of the order (1×2) while matrix [4 -5 -6] is of the order (1×3), i.e., the orders of our concerned matrices are not same.
Hence, as per the above mentioned rule, we cannot execute the difference of [3 -8] and [4 -5 -6], and yes, it is an impossible task.

Evaluate the expression below for x = -4 and y = 8 -X +5y + 2x
Answers
Here, given the values of x and y, we are told to evaluate the given expression
What we need to do here is to simply substitute the values of x and y into the given expression
Thus;
we have -x + 5y + 2x
By substitution, this becomes;
-(-4) + 5(8) + 2(-4)
= 4 + 40 -8
= 44 - 8
= 36
Given x = -4 and y = 8 , the expression -X +5y + 2x = 36

In order to calculate the percentage that enjoy New Years Eve only, we can use the diagram and formula below:
Using F to represent Fourth of July, N to represent New Years Eve and M to represent Memorial Day, the formula is:
[tex]P(N\text{ only})=P(N)-P(F\text{ and }N)-P(M\text{ and }N)+P(all\text{ }three)[/tex]From the given data, we have:
P(N) = 28% = 0.28
P(F and N) = 18% = 0.18
P(M and N) = 12% = 0.12
P(all three) = 5% = 0.05
So P(N only) is:

As per the concept of probability,
a) There are 1757600 number of possible license plates can there be in this state if repetition of letters and numbers is permitted
b) There are 1404000 number of possible license plates can there be in this state if repetition of letters and numbers is not permitted.
Probability:
Probability refer the possible way of occurring the particular event.
Given,
License plates in a particular state are to consist of 2 digits followed by 3 uppercase letters.
Here we need to determine the number of possible license plates for both repetition phase and non repetition phase.
Here we know that, license plates consist of 3 letters followed by 2 digits.
Let us consider the numbers on license plates be N
Let us consider the letters on license plates be L
Then the license plate consisting of 3 letters and 2 digits will be writen as,
=> LLLNN.
We know that the letters can be anything from A to Z.
There are 26 letter combinations for the first letter.
Again second and third letters can be anything from the 26 letters.
So, combination for letters = 26 × 26 × 26 = 17576
Similarly, the numbers can be anything from 0 to 9.
There are 10 combinations for both places.
Then the combination for numbers = 10 × 10 = 100
Therefore, the total number of combination for letters and numbers
=> 17576 × 100 = 1757600.
Therefore, there are 1757600 license plates can be made with repetition.
Similarly, for non repetition mode,
The number of letters for each place is reduced before,
So, the combination for the letter is,
=> 26 x 25 x 24 = 15600
Similarly, the combination of numbers is,
=> 10 x 9 = 90
Therefore, the total number of combination is,
=> 15600 x 90 = 1404000
