The temperature in Buffalo when it is 23 degrees Fahrenheit is equivalent to -5 degrees Celsius.
What is Fahrenheit and Celsius?Fahrenheit is a temperature scale that was created by Gabriel Fahrenheit in 1724. Fahrenheit is used primarily in the United States and a few other countries. The boiling point of water on this scale is 212 degrees Fahrenheit, while the freezing point is 32 degrees Fahrenheit.
The Celsius scale, on the other hand, is a temperature scale that is used throughout the world. It was created in 1742 by Swedish astronomer Anders Celsius. On this scale, the boiling point of water is 100 degrees Celsius, and the freezing point is 0 degrees Celsius.
How do I convert degrees Fahrenheit to degrees Celsius?The formula for converting degrees Fahrenheit to degrees Celsius is: C=5/9(F-32). C is the equivalent Celsius temperature, while F is the equivalent Fahrenheit temperature.
Let's put the formula into practice to answer the question, "If the temperature in Buffalo is 23 degrees Fahrenheit,

triangle ABD is right angled at B. On AD, there is a point C for which AC=CD and AB=BC. find angle DAB
The measure of the angle DAB for the right angled triangle ABD is found as 45°.
Explain about the angle sum property of the right angled triangle?A right-angled triangle has two acute angles that add up to 90°. The smallest angle is the one that is opposite the smallest side, and the greatest angle is the one that is against the largest side.
In a triangle, the two angles that face the two equivalent sides are also equal. There can only be one right angle and one obtuse angle in a triangle.
For the question-
Triangle ABC is right angled at B.
D point makes: AC = CD
And , AB = BC
Since ∠ABD = 90, given C is mid point.
Then, It is altitude on AD and it bisects the angle ABD into 2 equal halves as: ∠ABC = ∠CBD = 45.
Now, For triangle ABC
∠ABC = 45
∠BCA = 90
Then,
∠BAC + ∠ABC + ∠BCA = 180
∠BAC + 45 + 90 = 180
∠BAC = 180 - 135
∠BAC = 45°
Thus, the measure of the angle DAB for the right angled triangle ABD is found as 45°.

complete the square to re-write the quadratic function in vertex form.
pls help
Answer:
Y=x^2+7x-3
complete the square to re-write the quadratic function in vertex form.
pls help
Step-by-step explanation:
To complete the square, we need to add and subtract a constant term inside the parentheses, which when combined with the quadratic term will give us a perfect square trinomial.
y = x^2 + 7x - 3
y = (x^2 + 7x + ?) - ? - 3 (adding and subtracting the same constant)
y = (x^2 + 7x + (7/2)^2) - (7/2)^2 - 3 (the constant we need to add is half of the coefficient of the x-term squared)
y = (x + 7/2)^2 - 49/4 - 3
y = (x + 7/2)^2 - 61/4
So the quadratic function in vertex form is y = (x + 7/2)^2 - 61/4, which has a vertex at (-7/2, -61/4).
Which expressions are equivalent to (x−2)2
?
Select the correct choice
The expressions that are equivalent to (x-2)² is x² - 4x + 4. (option B)
Now, let's look at the expression (x-2)². This is a binomial expression that can be simplified by applying the rules of exponents. Specifically, we can expand this expression as follows:
(x-2)² = (x-2) * (x-2)
= x * x - 2 * x - 2 * x + 2 * 2
= x² - 4x + 4
So, the expression (x-2)² is equivalent to x² - 4x + 4.
However, the problem asks us to identify other expressions that are equivalent to (x-2)². To do this, we can use the process of factoring. We know that (x-2)² can be factored as (x-2) * (x-2). Using this factorization, we can rewrite (x-2)² as:
(x-2)² = (x-2) * (x-2)
= (x-2)²
So, (x-2)² is equivalent to itself.
Hence the correct option is (B).

She has 4 times as many $20 bills as $10 bills. She has 3 times as many $1 bills as $20 bills. She has a total of $204.
Please I need help answering it in 20 minutes
Ann has 60 $1 bills, 5 $10 bills, and 20 $20 bills.
Let's assume Ann has $1x, $10y, and $20z bills.
From the given information, we can write two equations based on the relationships between the numbers of bills:
z = 4y (Ann has four times as many $20 bills as $10 bills)
x = 3z (Ann has three times as many $1 bills as $20 bills)
We know that the total amount of money Ann has is $204, so we can write a third equation:
x + 10y + 20z = 204
Now we can use substitution method here, substitute equation 2 into equation 1 to get:
z = 4y
x = 3z
x = 3(4y) = 12y
Substituting these equations into equation 3, we get:
12y + 10y + 20(4y) = 204
42y = 204
y = 4.86
Since y must be a whole number (representing the number of $10 bills), we can round up to y = 5.
Using equation 1, we can find that z = 4y = 20 (representing the number of $20 bills).
Using equation 2, we can find that x = 3z = 60 (representing the number of $1 bills).

The value of X is 42.5 and Y is 90.98.
How to solve equations?
To solve an equation, you need to perform the same operation on both sides of the equation until you isolate the variable on one side and have a numerical value on the other side. The process of solving an equation generally involves the following steps:
Simplify both sides of the equation by combining like terms and following the order of operations.
Add or subtract the same value from both sides of the equation to isolate the variable term.
Multiply or divide both sides of the equation by the same non-zero value to isolate the variable term.
Check your solution by plugging it back into the original equation and verifying that it satisfies the equation.
Solving the given equations :
To solve for X, we can use inverse operations to isolate the variable. Since 10 is multiplied by X, we can use the inverse operation of division by 10 to isolate X. So, dividing both sides of the equation by 10 gives:
[tex]10x/10 = 425/10[/tex]
Simplifying the left side of the equation gives:
[tex]x = 42.5[/tex]
Therefore, X is 42.5.
To solve for Y, we can use similar steps. Since 81729 is divided by Y, we can use the inverse operation of multiplication by Y to isolate Y. So, multiplying both sides of the equation by Y gives:
[tex]81729 = 898.12 \times Y[/tex]
Simplifying the right side of the equation gives:
[tex]Y = 81729 / 898.12[/tex]
[tex]Y = 90.98[/tex]

A cylindrical tank is one-fifth full of oil. The cylinder has a base radius of 80 cm. The height of the cylinder is 200 cm. 1 litre 1000 cm3 How many litres of oil are in the tank? Round your answer to the nearest litre
The number of litres (Volume) of oil that is present in the tank of given dimension is calculated to be 806 litres (approximately).
The volume of any cylinder can be calculated using the formula,
V = πr²h
(Here V is the volume, r is the radius of the base, and h is the height of the cylinder)
As, the cylinder is one-fifth full of oil, which means that it is four-fifths empty. Therefore, the volume of oil in the tank is:
Volume of oil = (1/5) x Total Volume
Substituting the given values, we have:
Total Volume = π(80cm)²(200cm) = 4,031,240 cm³
Volume of oil = (1/5) x 4,031,240 cm³ = 806,248 cm³
Converting cm³ to litres, we have:
1 litre = 1000 cm³
Volume of oil = 806,248 cm³ ÷ 1000 = 806.248 litres
Therefore, after rounding of the final volume (806.248 litres) to the nearest litre, the final answer is found to be 806 litres of oil.

A skater has a mean score of 7. 25 points. An equation to determine the skaters total scores received from eight judges is equals to the x₁ + x₂ + x₃ + x₄ + x₅ + x₆ + x₇ + x₈ = 58.
Mean is called the average of the values and is calculated by dividing the addition of values by the total number of values. It is denoted by [tex]\bar X[/tex]. That is bar above X represents mean of x number of values. Mathematically, Mean = (Sum of all the values/Total number of values).We have in a skating compotion where each skater receives score from eight judges. Now, Mean or average of score points obtained by a skater = 7.25 points. Let the skater's received score from eight judges be equals to x₁,x₂,x₃,x₄,x₅,x₆,x₇, x₈. Total score received by skater = x₁ + x₂ + x₃ + x₄ + x₅ + x₆ + x₇ + x₈ and we have to write the equation to determine the skaters total scores. Now, in this case mean of scores means the sum of scores received by skaters from eight judges divided by eight (judges).
=> 7.25 = (x₁ + x₂ + x₃ + x₄ + x₅ + x₆ + x₇ + x₈)/8
=> x₁ + x₂ + x₃ + x₄ + x₅ + x₆ + x₇ + x₈
= 8× 7.25

In isosceles △ABC, points D and F are on leg CB while point E is on leg AB so that AC = AD = DE = EF = BF. Find the measures of the angles of △ABC. I WILL MARK BRAINLIEST PLEASE HELP FAST!!!!
The angles of △ABC can be determined by dividing 360 degrees by the number of congruent triangles. Therefore, each angle of △ABC measures 90 degrees as all the sides are congruent.
Since triangle ABC is isosceles, we know that angle BAC is equal to angle BCA. By drawing the perpendicular bisector of AC from point D, we can see that it intersects AC at its midpoint M. Therefore, we have AD = MC, and angle AMD is equal to angle CMD. Similarly, by drawing the perpendicular bisector of AC from point F, we have FC = CE, and angle CFE is equal to angle ECF. Since AD = DE and BF = EF, we have angle ADE = angle DEF and angle BEF = angle BFE. Therefore, we have four congruent triangles: △AMD, △BME, △ECF, and △FBC. Each of these triangles has angles that add up to 180 degrees, so we can find the measures of the angles of △ABC by dividing 360 degrees by the number of congruent triangles. Thus, each angle of △ABC measures 90 degrees.

Select the correct answer from each drop-down menu. The scatter plot shows the amount of water in a tank as measured every few minutes. The initial amount of water in tank was 0, 20, 100, or 120 gallons. The line of best fit shows that about 4/3, 3/4, 2/3, or 1/2 gallon(s) of water were lost per minute. The tank will be empty in about 0, 60, 80, or 90 minutes.
Given that the graph is falling downward, it can be seen that the graph is negative.
Before the tank's water level starts to drop, there are 120 gallons there.
Finding the slope of the graph will give us the amount of water that was lost every minute.
Slope is equal to a climb or a run.
increase = water in gallons
run equals time in minutes.
Slope equals y2 - y1 / x2 - x1
Two points will be chosen from the graph.
( 30, 80) and (60, 40) (60, 40)
Let x1=30, y1=80, x2=60, and y2=40.
Slope = 40 - 80 / 60 - 30
Slope = -40 / 30
Slope = -4/3
The result in the negative represents a loss in gallons of water per minute.
According to the line of best fit, a gallon of water was lost every minute or so.
The graph indicates that the tank will be empty in around 60 minutes.

In this problem you will use variation of parameters to solve the nonhomogeneous equation y" – 4y' + 4y = -6e2t A. Write the characteristic equation for the associated homogeneous equation.

Compute the following integrals. ✓ W dt = 929 dt = и D. Write the general solution. (Use c1 and c2 for cy and c2). y= (Note: Your general solution will only be correct if it is a general solution to the differential equation.)
A. The characteristic equation for the associated homogeneous equation is:
r² - 4r + 4 = 0
B. The characteristic equation has a repeated root of 2, so the fundamental solutions for the associated homogeneous equation are:
[tex]y1(t) = e^(2t)[/tex]
[tex]y2(t) = te^(2t)[/tex]
The Wronskian of these solutions is:
[tex]W(y1, y2) = det([y1 y2; y1' y2']) = det([e^(2t) te^(2t); 2e^(2t) (2t+1)e^(2t)]) = 4e^(4t)[/tex]
So,[tex]W(y1, y2) = 4e^(4t)[/tex]
C. We need to compute the following integrals:
[tex]W(t)dt = ∫(2e^(2t))(te^(2t))dt = ∫(2t)e^(4t)dt = (1/4)te^(4t) - (1/8)e^(4t) + C1[/tex]
[tex]W(dt) = ∫(4e^(4t))dt = (1/4)e^(4t) + C2[/tex]
D. The general solution is:
[tex]y(t) = c1 y1(t) + c2 y2(t) + yp(t)[/tex]
To find a particular solution, we assume yp(t) takes the form:
[tex]yp(t) = A e^(2t)[/tex]
where A is a constant to be determined. We substitute this into the nonhomogeneous equation and solve for A:
[tex]y'' - 4y' + 4y = -6e^(2t)[/tex]
[tex](4A - 4A) e^(2t) = -6e^(2t)[/tex]
[tex]0 = -6e^(2t)[/tex]
This equation has no solution, so we need to modify our assumption for yp(t) by multiplying by t:
[tex]yp(t) = A t e^(2t)[/tex]
We substitute this into the nonhomogeneous equation and solve for A:
[tex]y'' - 4y' + 4y = -6e^(2t)[/tex]
[tex](8A - 8A + 4A) te^(2t) = -6e^(2t)[/tex]
[tex]4A = -6[/tex]
[tex]A = \frac{-3}{2}[/tex]
So, a particular solution is:
[tex]yp(t) = (-3/2) t e^(2t)[/tex]
Therefore, the general solution to the nonhomogeneous equation is:
[tex]y(t) = c1 e^(2t) + c2 t e^(2t) - (3/2) t e^(2t)[/tex]
or
[tex]y(t) = (c1 - (3/2) t) e^(2t) + c2 t e^(2t)[/tex]
where c1 and c2 are constants determined by initial conditions.
A non-homogeneous equation is a type of mathematical equation that involves both homogeneous and nonhomogeneous terms. In general, a homogeneous equation is one in which all the terms have the same degree, whereas a nonhomogeneous equation contains terms of different degrees.
In the context of linear algebra, a nonhomogeneous equation is typical of the form Ax = b, where A is a matrix, x is a vector, and b is a non-zero vector. The term "nonhomogeneous" refers to the fact that b is not the zero vector. In differential equations, a nonhomogeneous equation is one that includes a forcing function or input that is not equal to zero. The solution to such an equation can be found by adding the particular solution to the general solution of the corresponding homogeneous equation.

Answer:
The midpoint of the diameter is (4, 1)
This is the center of the circle
=====================================================
Explanation:
Add up the x coordinates and divide in half
(-1+9)/2 = 8/2 = 4
The x coordinate of the midpoint is x = 4
Repeat for the y coordinates
(4 + (-2))/2 = (4-2)/2 = 2/2 = 1
The y coordinate of the midpoint is y = 1
The midpoint is located at (x,y) = (4,1)
The midpoint of any diameter is the center of the circle. This is because all diameters go through the center.
The distance from the center to either endpoint represents the radius of the circle (aka half the diameter).
The cylinder below has a curved surface area of 408πm² and a length of 17 m.
Work out the total surface area of the cylinder.
Answer: The total surface area of the cylinder is 850π m².
Step-by-step explanation:
The cylinder has a curved surface area of 408π m², which is the area of the lateral surface of the cylinder. The lateral surface of a cylinder is the curved surface that connects the top and bottom bases of the cylinder.
The formula for the lateral surface area of a cylinder is given by: Lateral Surface Area = 2πrh, where r is the radius of the cylinder and h is the height (or length) of the cylinder.
We are given that the length of the cylinder is 17 m. Since the length of a cylinder is the same as its height, we can substitute h = 17 m into the formula for the lateral surface area to get:
408π m² = 2πr(17 m)
Simplifying this equation, we get:
r = 12 m
Now that we know the radius of the cylinder, we can find the total surface area of the cylinder. The formula for the total surface area of a cylinder is given by:
Total Surface Area = 2πr(r + h)
Substituting r = 12 m and h = 17 m into this formula, we get:
Total Surface Area = 2π(12 m)(12 m + 17 m) = 850π m²
Therefore, the total surface area of the cylinder is 850π m².
It’s not 1507 please help me
Answer:
Below
Step-by-step explanation:
Mass of bouncies + box = 17342 subtract mass of box from both sides
mass of bouncies = 17342 - 429 = 16913 g
Unit mass per bouncy = 505 g / 45 bouncy
Number of Bouncies = 16913 gm / ( 505 g / 45 bouncy ) = 1507.1 bouncies
With the given info, I am afraid it IS 1507 bouncies in the box
maybe since the question asks for APPROXIMATE number, the answer is 1510 bouncies ( rounded answer) ....or 1500
