Describe the rotation as a (a) counterclockwise rotation and (b) clockwise rotatio
a. 90 degrees counterclockwise rotation about the origin
b. 270 degrees clockwise rotation about the origin
Write a rule for the rotation.
After the 90° counter clockwise rotation and the 270° clockwise rotation, the rule of the rotation is (-y, x)
Rotation:
Rotation refers the circular movement of an object around a center. And it is possible to rotate different shapes by an angle around the center point.
Given,
Here we need to find the rotation rule,
a. 90 degrees counterclockwise rotation about the origin
b. 270 degrees clockwise rotation about the origin.
Here the mapping rule is for rotation of 270 degrees clockwise is as follows.
We know that there are 360 degrees in one revolution.
So, the general rule for rotation of an object 90 degrees is (x, y) ---> (-y, x).
And the 270 degrees clockwise rotation is the same as 90 degrees anticlockwise rotation (x, y) ---> (-y, x)
Therefore, the initial figure is always called the pre-image (90 degrees), while the rotated figure will be called the image (270 degrees).
Therefore, the rule is (-y, x).

How do you solve 3(x−5)=12?
Answer:
9
Step-by-step explanation:
3(x-5)=12
Use distributive property on with the 3 and parenthesis (3 times x and 3 times -5)
3x-15=12
Add fifteen to both sides (15 on the left side cancels out)
3x=27
Divide both sides by 3 (3 on the left side cancels out)

beth and her friends are watching an ice hockey game, so beth decides to buy 4 cups of hot chocolate to share. she figures she'll spend at least $14 on the hot chocolate in all. let x represent how much beth expects each cup of hot chocolate to cost. which inequality describes the problem?
The inequality that describes the problem is: x*4 >= $14.
This inequality can be read as: "the cost of 4 cups of hot chocolate (x) multiplied by 4 is greater than or equal to $14."
We know that Beth expects to spend at least $14 on the hot chocolate in total, and she's buying 4 cups, so we can set up the inequality with the number of cups and the minimum amount she wants to spend.
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

A recipe needs cup of butter for every 2 cups of flour. if you plan to use 3 cups of flour, how much butter will you need?
You will need amount of 1.5 cups of butter if you plan to use 3 cups of flour in your recipe.
To calculate how much butter is needed for 3 cups of flour in a recipe, start by identifying that the recipe requires a ratio of 1 cup of butter for every 2 cups of flour. To get the amount of butter needed for 3 cups of flour, multiply 1 cup of butter by 1.5. This will give you 1.5 cups of butter, which is the amount needed for 3 cups of flour. Therefore, you will need 1.5 cups of butter if you plan to use 3 cups of flour in your recipe. To ensure accuracy, it is recommended to measure the ingredients carefully and double check your calculations before proceeding.

Answer:
point form : (9,2) equation form : x=9 y=2
Step-by-step explanation:
Given the function: f(x) = 2x² – 3x, calculate f(a+h) - ƒ (a). h a. 4a - 3 + h b. 4a - 3 - h c. 4a 3 3h d. 4a - 3 - 2h e. 4a3+ 2h
The option that represents the result correctly is:
c. 4ah + 2h² - 3h
To calculate f(a+h) - f(a), we substitute the expressions for f(a+h) and f(a) into the equation and simplify:
f(a+h) - f(a) = (2(a+h)² - 3(a+h)) - (2a² - 3a)
= 2(a² + 2ah + h²) - 3(a+h) - 2a² + 3a
= 2a² + 4ah + 2h² - 3a - 3h - 2a² + 3a
= 4ah + 2h² - 3h
So, the correct answer is:
f(a+h) - f(a) = 4ah + 2h² - 3h
Therefore, the option that represents the result correctly is:
c. 4ah + 2h² - 3h

sketch the vector −−→ p q in the plane from initial point p ( 2 , − 2 ) to terminal point q ( 3 , − 5 ) , then
the vector pq is drawn from origin to point (1,-3)
To sketch the vector p q in the plane, we start at the initial point p (2, -2) and end at the terminal point q (3, -5).
First, draw a coordinate system with x and y axes. Then plot the point p at (2, -2) and the point q at (3, -5).
Next, draw an arrow from point p to point q. The length of the arrow represents the magnitude of the vector, and the direction of the arrow represents the direction of the vector.
The vector p q can be represented as the difference between the coordinates of q and p:
p q = (3, -5) - (2, -2) = (1, -3)
So the vector pq is drawn from origin to point (1,-3)

Which recurrence relation describes a function that has the same asymptotic growth as , defined by the recurrence relation: Group of answer choices
The recurrence relation that describes a function with the same asymptotic growth as f(n), defined by the recurrence relation, is f(n) = f(n-1) + g(n), where g(n) is any function that grows slower than or at the same rate as f(n).
In this recurrence relation, f(n) represents the function being described, f(n-1) represents the previous term in the sequence, and g(n) represents the additional term being added at each step.
By choosing a g(n) that grows slower than or at the same rate as f(n), we ensure that the additional term does not significantly affect the overall growth of the function.
This results in both f(n) and the given recurrence relation having the same asymptotic growth.
It is important to note that the exact form of g(n) is not specified in the question, so there are multiple possible answers that would satisfy the condition of having the same asymptotic growth.

determine the solution of the following simultaneous equations by cramer’s rule. 1 5 2 5 x x x x 2 4 20 4 2 10
The solution to the given simultaneous equations using Cramer's Rule is:
x = 4/17
y = 0
z = 20/17
To solve the simultaneous equations using Cramer's Rule, we need to set up the matrix equation and calculate determinants. Let's denote the variables as x, y, and z.
The given system of equations can be represented in matrix form as:
| 1 5 2 | | x | | x |
| | * | | = | |
| 2 4 20 | | y | | x |
| | | | = | |
| 4 2 10 | | z | | x |
To solve for the variables x, y, and z, we will use Cramer's Rule, which states that the solution is obtained by dividing the determinant of the coefficient matrix with the determinant of the main matrix.
Step 1: Calculate the determinant of the coefficient matrix (D):
D = | 1 5 2 |
| 2 4 20 |
| 4 2 10 |
D = (1*(410 - 220)) - (5*(210 - 44)) + (2*(22 - 44))
D = (-16) - (40) + (-12)
D = -68
Step 2: Calculate the determinant of the matrix replacing the x-column with the constant terms (Dx):
Dx = | x 5 2 |
| x 4 20 |
| x 2 10 |
Dx = (x*(410 - 220)) - (5*(x10 - 220)) + (2*(x2 - 410))
Dx = (-28x) + (100x) - (76x)
Dx = -4x
Step 3: Calculate the determinant of the matrix replacing the y-column with the constant terms (Dy):
Dy = | 1 x 2 |
| 2 x 20 |
| 4 x 10 |
Dy = (1*(x10 - 220)) - (x*(210 - 44)) + (4*(2x - 410))
Dy = (-40x) + (56x) - (16x)
Dy = 0
Step 4: Calculate the determinant of the matrix replacing the z-column with the constant terms (Dz):
Dz = | 1 5 x |
| 2 4 x |
| 4 2 x |
Dz = (1*(4x - 2x)) - (5*(2x - 4x)) + (x*(22 - 44))
Dz = (2x) - (10x) - (12x)
Dz = -20x
Step 5: Solve for the variables:
x = Dx / D = (-4x) / (-68) = 4/17
y = Dy / D = 0 / (-68) = 0
z = Dz / D = (-20x) / (-68) = 20/17
Therefore, the solution to the given simultaneous equations using Cramer's Rule is:
x = 4/17
y = 0
z = 20/17

6. Combine the following logarithms into a single logarithm. Be sure to show all your work and explain which log properties you used for each step. Do not overly simplify.1 over 6 log subscript 4 z plus log subscript 4 open parentheses z squared minus 36 close parentheses minus 7 over 6 log subscript 4 open parentheses z minus 6 close parentheses
Given:
\(\frac{1}{6}\log _4z+\log _4(z^2-36)-\frac{7}{6}\log _4(z-6)\)To combine these logarithms into a single logarithm, the first thing we need to do is to re-write the expression as a single logarithm with coeffient.
\(\frac{1}{6}\log _4z+\log _4(z^2-36)-\frac{7}{6}\log _4(z-6)=\frac{\log _4\sqrt[6]{z}+\log _4(z^2-36)}{\log _4\sqrt[6]{(z-6)^7}}\)Next, we will use the Product Rule to simplify the numerator.
Product Rule states that:
\(\log _b(MN)=\log _bM+\log _bN\)Applying it to the numerator:
\(\log _4\sqrt[6]{z}+\log _4(z^2-36)=\log _4(\sqrt[6]{z}(z^2-36))\)We will now have a new expression:
\(\frac{\log_4(\sqrt[6]{z}(z^2-36))}{\log_4\sqrt[6]{(z-6)^7}}\)Next, we will factor out the logarithm.
\(\frac{\log_4(\sqrt[6]{z}(z^2-36))}{\log_4\sqrt[6]{(z-6)^7}}=\log _4(\frac{\sqrt[6]{z}(z^2-36)}{\sqrt[6]{(z-6)^7}})\)Therefore, the final answer would be:
\(\log _4(\frac{\sqrt[6]{z}(z^2-36)}{\sqrt[6]{(z-6)^7}})\)Which statement is true?
