find the measure of GTR
Answer:
\(\displaystyle 68° = m\angle{GTR}\)
Step-by-step explanation:
\(\displaystyle [5f + 83]° = [4f + 80]° \hookrightarrow \frac{3}{-1} = \frac{-f}{-1} \\ \\ -3 = f \\ \\ \\ [4[-3] + 80]°; [-12 + 80]° \\ \\ 68° = m\angle{FTH}\)
As you can see, we plugged the m-value into the expression for angle \(\displaystyle FTH\)because if you recall, you can tell that angles \(\displaystyle FTH\:and\:GTR\)are vertical angles, and accourding to the Vertical Angles Theorem, these angles are considered congruent, therefore sixty-eight degrees is also the measure of angle \(\displaystyle GTR.\)

Find the solution to the system of equations given below using elimination.
3x + 2y = -3
9x + 4y = 3
To solve the system of equations using elimination, we'll eliminate one variable by manipulating the equations.
Let's follow the steps: Given equations: 3x + 2y = -3. 9x + 4y = 3. To eliminate the y variable, we can multiply equation (1) by 2 and equation (2) by -1, which will allow us to add the two equations together: 2(3x + 2y) = 2(-3). -1(9x + 4y) = -1(3). Simplifying the equations: 6x + 4y = -6. -9x - 4y = -3. Now, let's add the two equations together: (6x + 4y) + (-9x - 4y) = -6 + (-3). Simplifying the equation: -3x = -9. Dividing both sides by -3: x = 3. Now that we have the value of x, we can substitute it back into one of the original equations to solve for y. Let's use equation (1): 3(3) + 2y = -3. 9 + 2y = -3. Subtracting 9 from both sides: 2y = -12. Dividing both sides by 2: y = -6. Therefore, the solution to the system of equations is x = 3 and y = -6.
The solutions of system of equations can be represented as the ordered pair (x, y) = (3, -6).

Mom is getting food ready for my birthday party! Including me, there will be 22 people at the party. Mom is baking cupcakes for us! She can bake 12 cupcakes per batch. How many batches should I tell Mom to make so we can each have 3 cupcakes?
Answer:
She will need to make a total of 5 1/2 batches.

Let X and Y be discrete random variables with joint probability function f(x, y) = (1/54)(x + 1)(y + 2) for x = 0, 1, 2; y = 0, 1, 2. What is E[Y| X = 1]?
A. (y+2)/9
B. (y2+ 2y)/9
C. 11/27
D. 1E.11/9
X and Y be discrete random variables with joint probability function is answer is (D) 11/9.
To find E[Y| X = 1], we need to use the conditional expectation formula:
E[Y| X = 1] = Σy y P(Y = y| X = 1)
Using the joint probability function, we can find P(Y = y| X = 1):
P(Y = y| X = 1) = f(1, y) / Σy f(1, y)
P(Y = y| X = 1) = ((1/54)(1 + 1)(y + 2)) / ((1/54)(1 + 1)(0 + 2) + (1/54)(1 + 1)(1 + 2) + (1/54)(1 + 1)(2 + 2))
P(Y = y| X = 1) = (y + 2) / 9
Substituting this into the formula for \(E[Y| X = 1],\) we get:
E[Y| X = 1] = Σy y P(Y = y| X = 1)
E[Y| X = 1] = (0)(1/9) + (1)(3/9) + (2)(5/9)
E[Y| X = 1] = 11/9
Therefore, the answer is (D) 11/9.

B.$4.95 per pizza
C.$7.25 per pizza
D.$5.75 per pizza
Answer:
A
Step-by-step explanation:
97.5 / 15 = 6.5
The unit cost is $6.50 per pizza
What is the cost per unit in math?The "Unit Price" (or "unit cost") tells you the cost per liter, per kilogram, per pound, etc. of what you want to buy. How do I calculate cost per unit?To calculate the cost per unit, add all of your fixed costs and all of your variable costs together and then divide this by the total amount of units you produced during that time period.Based on the given conditions,
formulate: $97.50 ÷ 15
Convert decimal to fraction: 975÷10÷15
Divide a fraction by multiplying its reciprocal : \(\frac{975}{10}\) ×\(\frac{1}{15}\)
Cross out the common factor: \(\frac{65}{10}\)
Cross out the common factor: \(\frac{13}{2}\)

Find the equation of the tangent to the curve at the point where x = 1. f(x)=x√1+3x²
the equation of the tangent to the curve at the point where x = 1 is:
y = 8x - 6
To find the equation of the tangent to the curve at the point where x = 1, we need to determine the slope of the tangent at that point and then use the point-slope form of a line to find the equation.
First, let's find the slope of the tangent. We can do this by finding the derivative of the function f(x) = x√(1 + 3x²) and evaluating it at x = 1.
f(x) = x√(1 + 3x²)
Taking the derivative of f(x) with respect to x:
f'(x) = √(1 + 3x²) + x * (1/2√(1 + 3x²)) * (6x)
Now, we can evaluate f'(x) at x = 1:
f'(1) = √(1 + 3(1)²) + 1 * (1/2√(1 + 3(1)²)) * (6(1))
Simplifying this expression:
f'(1) = √(1 + 3) + (1/2√(1 + 3)) * 6
f'(1) = √4 + (1/2√(4))* 6
f'(1) = 2 + (1/2)(2) * 6
f'(1) = 2 + 1 * 6
f'(1) = 2 + 6
f'(1) = 8
So, the slope of the tangent at x = 1 is 8.
Now that we have the slope, we can use the point-slope form of a line, which is:
y - y₁ = m(x - x₁)
Where:
m is the slope
(x₁, y₁) is the point on the line (x = 1, f(1))
Using the point-slope form, we can write the equation of the tangent:
y - f(1) = 8(x - 1)
Now, substitute the value of f(1) into the equation:
y - f(1) = 8(x - 1)
y - f(1) = 8x - 8
Since we know that f(1) = 1√(1 + 3(1)²), we can substitute it into the equation:
y - √(1 + 3(1)²) = 8x - 8
y - 2 = 8x - 8
y = 8x - 6
Therefore, the equation of the tangent to the curve at the point where x = 1 is:
y = 8x - 6

Kendrick attends a private school where he must wear a uniform. Last year, the price of the uniform was $52. This year's uniform price was $65. What is the percent of increase in the cost of the uniform?
The percent increase in the cost of the uniform from last year to this year is 25%.
What is the percent of increase in the cost of the uniform?To find the percent increase in the cost of the uniform from last year to this year, we need to calculate the difference between the two prices, divide it by the original price, and then multiply by 100 to express the result as a percentage.
The difference between this year's price and last year's price is:
$65 - $52 = $13
The original price (last year's price) is $52.
So the percent increase in the cost of the uniform is:
percent increase = (difference / original price) x 100
percent increase = ($13 / $52) x 100
percent increase = 0.25 x 100
percent increase = 25%
Therefore, the percent increase in the cost of the uniform from last year to this year is 25%.

What are dilation rules?
Dilation rules refer to the mathematical rules and formulas used to calculate the image of a point, shape, or figure after it has undergone a dilation transformation.
Here are some of the most common dilation rules:
Scale Factor: The scale factor is the ratio of the length of a line segment in the image to the length of the corresponding line segment in the pre-image. For example, a dilation with a scale factor of 2 will double the length of the line segment.Center of Dilation: The center of dilation is a fixed point in the plane that remains the same distance from all points on the image and the pre-image. The center of dilation is used as a reference point to determine the new coordinates of the image. Distance Formula: To find the image of a point after dilation, the distance formula can be used. The distance formula calculates the distance between two points in the plane. Ratio: The ratio of the distance between two points on the pre-image to the distance between the corresponding points on the image is equal to the scale factor.Similarity: When dilation is done with a scale factor greater than 1, the image and pre-image figures are similar. Congruence: When dilation is done with a scale factor equal to 1, the image and pre-image figures are congruent.It's important to note that, the rules mentioned above are general rules of dilation and they might vary depending on the specific dilation transformation.

Question 5: Is 4n^3 + 5n^2 + 3n + 3 = O(n^2) ?
Question 6: Is n^2 + 10n + 5 = Ω(n2) ?
Question 7: Is 2n^3 + 5 = Ω(n3) ?
Question 8: Is 3n^2 + 2n + 5 = Ω(n3) ?
Question 5: No, 4n^3 + 5n^2 + 3n + 3 = O(n^2) is false. Question 6: Yes, n^2 + 10n + 5 = Ω(n^2) is true. Question 7: Yes, 2n^3 + 5 = Ω(n^3) is true. Question 8: No, 3n^2 + 2n + 5 = Ω(n^3) is false.
In Big O notation, the statement "f(n) = O(g(n))" implies that the function f(n) grows asymptotically no faster than g(n). In Question 5, the function 4n^3 + 5n^2 + 3n + 3 does not have an upper bound of n^2, as the highest degree term is n^3. Therefore, the statement "4n^3 + 5n^2 + 3n + 3 = O(n^2)" is false.
In Question 6, the function n^2 + 10n + 5 does have an upper bound of n^2, as the highest degree term is n^2. Thus, the statement "n^2 + 10n + 5 = Ω(n^2)" is true, indicating that the function grows at least as fast as n^2.
Similarly, in Question 7, the function 2n^3 + 5 has an upper bound of n^3 since the highest degree term is n^3. Therefore, the statement "2n^3 + 5 = Ω(n^3)" is true.
Finally, in Question 8, the function 3n^2 + 2n + 5 does not have an upper bound of n^3, as the highest degree term is n^2. Hence, the statement "3n^2 + 2n + 5 = Ω(n^3)" is false.

The ratio of Cheko's books to Miko's books is 5 : 12. Miko has 48 books. How many books must Miko give to Cheko so that both will have the same number of books?
Answer:
Step-by-step explanation:
Cheko's books (C) to Miko's books (M) is 5 : 12
C/M = 5/12
C = (5/12)M
We know M=48, so:
C = (5/12)(48)
C = 5*(48/12)
C = 5*4
C = 20 [Cheko has 20 books]
We want M=C, so Miko must give Cheko x number of books so that C/M is (1/1) or 1.
C/M is currently 20/48
We want C/M = (20+x)/(48-x) = 1
(20+x)/(48-x) = 1
(20+x) = (48-x)
2x = 28
x = 14
Once Miko gives Cheko 14 books, they each have the same number: (48-14)/(20+14) = 34/34. Everyone's happy. [We don't know WHICH books Miko chose to give to Cheko. Rumor is all 14 were math books]
