i need help, how do you do this
Answer: So you are going to make an equation first.
Step-by-step explanation:
first we know that for the first 2 hours the snow fell at an inch an hour. so we are going to make our first plots ( I suggest using an online site like geogebra or desmos to start out with before plotting for your assingment)
our first plot is going to be at (1,1) or 1 over and 1 up. remember points are in the form of (x,y). then (2,2)
Now we see that it has changed now there is no new snow for 6 hours so you are going to have a flat line so its going to be (2,2) then its going to continue that way as (3,2),(4,2), (5,2) (6,2)(7,2)(8,2).
It starts snowing again and now we have a new thing to plot the snow is falling at a constant of 3 inches an hour for the next 5 hours so now we are going to plot hte points to get our points we are going add 3 inches to our current inches each new hour. so its going to be (9,(2+3)) which is (9,5) and continue on doing that so we will have the plots (10,8) (11,11) (12,14) (13,17). and now we connect our plots by creating segments so then you do that on your thing and youre set to go I hope this helps.
Solve the following system of equations using substitution (Enter your answer as an ordered pair, including the parentheses and comma.)
-3x+6y=12
2y=x+4
The system of equations has infinite solutions, both equations represent the same line.
How to solve the system of equations?
Here we have the following system of equations:
-3x+6y=12
2y=x+4
And we want to solve this by substitution, first, we can rewrite the first equation as:
-3x + 3*(2y) = 12
Now we can substitute the second equation 2y = x + 4 in the parenthesis, we will get:
-3x + 3*(x + 4) = 12
Now we can solve this for x.
-3x + 3x + 12 = 12
12 = 12
So this is true for any value of x, which means that both equations represent the same line (thus the system has infinite solutions).

Whats 21 square root of 98 divided by 7 square root of 21
The 21 square root of 98 divided by 7 square root of 21 = 21√98 / 7√21 = 6.4807407
A square root of a number x is a number y such that y2 = x; in other words, a number y who's square and the result of multiplying the number by itself, or y ⋅ y, is x.
Every nonnegative real number x has a unique nonnegative square root, called the principal square root, which is denoted by √where the symbol √ is called the radical sign.
Every positive number x has two square roots: √ which is positive, and -√ which is negative. The two roots can be written more concisely using the ± although the principal square root of a positive number is only one of its two square roots, the designation "the square root" is often used to refer to the principal square root.

Answer:
16 meters
Step-by-step explanation:
\( In\: \odot F, \: \overline {RS} \) is tangent to the circle at point R and FR is radius.
\( \therefore RF\perp RS\) (Tangent radius theorem)
\( \therefore m\angle FRS = 90\degree \)
So, \( \triangle FRS\) is right angled triangle and FS is its hypotenuse.
Let FR = FT = r
FS = FT + ST = r + 9
Now, by Pythagoras theorem:
\(FR^2 + RS^2 = FS^2 \\ \therefore r^2 + (15)^2 = (r + 9)^2 \\ \therefore \cancel{ r^2} +225 = \cancel{ r^2} + 18r + 81\\ \therefore \: 225 = 18r + 81 \\ \therefore \: 225 - 81= 18r \\ \therefore \: 144= 18r \\ \therefore \: r = \frac{144}{18} \\ \therefore \: r =8 \: m\\ \implies \: d = 2r = 2(8) = 16 \: m\)

In a recent year, the percentage of first-time California Bar Exam takers that passed the July exam was 52%, while the percentage of repeaters that passed was 22%. Define x as a random variables representing the number of times a randomly selected individual will take the bar exam until he/she passes. Assume the percentages given here hold for every subsequent exam. Also, assume that the individual selected is willing to make a maximum of seven attempts, if necessary, but if he/she fails on the seventh attempt, that is---it's time to move on to another career.
a. Show the probability distribution for this random variable in a table format.
b. Compute the expected value of the random variable.
The probability distribution for the random variable x can be shown in a table format, and the expected value can be computed by multiplying each possible outcome by its corresponding probability and summing them up.
The expected value of the random variable can be computed by multiplying each possible number of attempts by its corresponding probability and summing up the results.
a. The probability distribution for the random variable x, representing the number of times a randomly selected individual will take the bar exam until he/she passes, can be shown in a table format as follows:
Number of Attempts (x) Probability (P(x))
1 0.52
2 (1-0.52) * 0.22
3 (1-0.52) * (1-0.22) * 0.22
4 (1-0.52) * \((1-0.22)^2\) * 0.22
5 (1-0.52) * \((1-0.22)^3\) * 0.22
6 (1-0.52) * \((1-0.22)^4\) * 0.22
7 (1-0.52) * \((1-0.22)^5\) * 0.22
In this table, the probability for passing on the first attempt is given as 52% (0.52). For subsequent attempts, the probability of passing is calculated as the complement of the previous probabilities multiplied by the passing rate for repeaters (22%).
For example, the probability of passing on the second attempt is calculated as (1-0.52) * 0.22. The probability of passing on the third attempt is calculated as (1-0.52) * (1-0.22) * 0.22, and so on.
b. To compute the expected value of the random variable x, we need to multiply each possible number of attempts by its corresponding probability and sum up the results.
Expected Value (E(x)) = (1 * P(1)) + (2 * P(2)) + (3 * P(3)) + (4 * P(4)) + (5 * P(5)) + (6 * P(6)) + (7 * P(7))
In this case, the expected value can be calculated by substituting the probabilities from the probability distribution table into the formula.

let A and B be nxn matrices. We say that A is similar to B if B = P^-1 AP for some invertible matrix P.
Suppose that if A and B are nxn matrices such that A is similar to B. Prove that if A is invertible then B is invertible and A^-1 is similar to B^-1.
If A is similar to B, and A is invertible, then B is also invertible and the inverse of A, denoted as A^(-1), is similar to the inverse of B, denoted as B^(-1). This can be proved by showing that B^(-1) = (P^(-1))^(-1) A^(-1) P^(-1), where P is the invertible matrix that relates A and B.
Given that A is similar to B, we have B = P^(-1)AP for some invertible matrix P. If we multiply both sides of this equation by P, we get BP = P(P^(-1)AP). Since P^(-1)P is the identity matrix, we have BP = (PP^(-1))AP, which simplifies to BP = A.This shows that B is invertible, with B^(-1) = P^(-1)AP.

Which algebraic expression would be used to denote a trisomic organism? a. 1n b. 3n c. 2n - 1 d. 2n + 1 e. 2n + 2.
The correct answer to the given question is d. 2n+1. The other options, such as 1n, 3n, 2n-1, and 2n+2, do not accurately represent the chromosome number of a trisomic organism.
A trisomic organism is one that has an extra copy of a chromosome in its genome. This means that it has three copies of a particular chromosome instead of the usual two, which can have significant implications for the organism's development and health.
In terms of algebraic notation, the chromosome number of a trisomic organism would be denoted as 2n+1, where "n" represents the normal diploid number of chromosomes for that organism. The "2n" represents the normal two sets of chromosomes, and the "+1" represents the extra chromosome.
Therefore, the correct answer to the given question is d. 2n+1. The other options, such as 1n, 3n, 2n-1, and 2n+2, do not accurately represent the chromosome number of a trisomic organism. It is important to note that trisomies can occur for any chromosome, not just the sex chromosomes, and can have varying effects depending on which chromosome is affected.

Create a linear model for Sepal.Width in terms of Sepal.Length and Species, without allowing interactions between Sepal.Length and Species. What is the equation for your model
To create a linear model for Sepal.Width in terms of Sepal.Length and Species without allowing interactions between Sepal.Length and Species, you can use the following equation: Sepal.Width = b0 + b1 * Sepal.Length + b2 * Species_1 + b3 * Species_2
Here,
- Sepal.Width is the dependent variable you want to predict
- Sepal.Length is the independent variable
- Species_1 and Species_2 are binary (dummy) variables representing the different species, excluding one species as the reference category.
- b0 is the intercept term
- b1, b2, and b3 are coefficients that need to be estimated using linear regression
To estimate the coefficients, you will need to perform linear regression on the given data. Once you have estimated the coefficients (b0, b1, b2, and b3), you can plug them into the equation to predict Sepal.Width for any given Sepal.Length and Species. Note that in order to provide the exact equation, data and regression results are necessary.

Find the general solution to the differential equation (2 – 2) y'+y=3x² + 2x. Assume x > 2.
The given differential equation is (0)y' + y = 3x^2 + 2x, which can be rewritten as y = 3x^2 + 2x.
The homogeneous equation is (0)y' + y = 0, which has a general solution of y = c, where c is a constant.
To find the particular solution, we can use the method of undetermined coefficients. Since the right-hand side of the equation is a polynomial of degree 2, we assume a particular solution of the form y = Ax^2 + Bx + C.
Differentiating y with respect to x, we get y' = 2Ax + B.
Substituting y and y' back into the original equation, we get:
(0)(2Ax + B) + (Ax^2 + Bx + C) = 3x^2 + 2x
Simplifying, we get:
Ax^2 + Bx + C = 3x^2 + 2x
Comparing coefficients, we get:
A = 3, B = 2, C = 0.
Therefore, the particular solution is y = 3x^2 + 2x.
The general solution is then the sum of the homogeneous equation and particular solutions:
y = c + 3x^2 + 2x, where c is a constant.

A 15 inch tall plant grows 3 inches per month. What would be the height of the plant after 8 months?
The height of the plant after 8 months would be 39 inches.
The plant is currently 15 inches tall and it grows at a rate of 3 inches per month. To find the height of the plant after 8 months, we can use the formula:
Height after n months = Initial height + (Rate of growth × Number of months)
Substituting the given values into the formula, we have:
Height after 8 months = 15 inches + (3 inches/month × 8 months)
Calculating the expression inside the parentheses:
Height after 8 months = 15 inches + (24 inches)
Adding the two values together:
Height after 8 months = 39 inches
Therefore, the height of the plant after 8 months would be 39 inches.
In summary, starting from an initial height of 15 inches, the plant grows 3 inches per month. After 8 months, the height of the plant would be 39 inches.
