⭐What is the circumcenter of a triangle?
the point of concurrency (intersection) of the perpendicular bisectors⭐What are the properties of a circumcenter?
the perpendicular bisectors bisect each side and form a right anglethe distance from each vertex to the circumcenter is congruent (the same)Let's use the properties of a circumcenter to solve for YX.
Because the circumcenter is the intersection of the perpendicular bisectors :
If Y is the circumcenter, then XU = SX.
If Y is the circumcenter, then ∠UXY = 90°.
If ∠UXY = 90°, then ∠SXY = 90°.
If SX = 13, then XU = 13 .
If YT = 14, then YU = 13.
If YU = 13, then YS = 13.
ΔUXY and ΔSXY. YX is the height of both triangles.
Therefore, we can use the Pythagorean Theorem ([tex]c^2 = a^2 + b^2[/tex]) to solve for YX.
Set up the equation. Let c = the hypotenuse and let a and b = the legs:
[tex]c^2 = a^2 + b^2[/tex]
[tex]14^2 = 13^2 + YX^2[/tex]
[tex]196 = 169 + XY^2[/tex]
[tex]27 = XY^2[/tex]
[tex]\sqrt{27} = \sqrt{XY^2}[/tex]
∴ 5.1/5.2 = XY

Find the inverse of f(x) = 2(x-2) ^2 +1
Find the inverse of y = ^3√x-3
Answers
Answer:
f^-1(x) = 2(x-2)^2 + 1
f^-1(x) = (x+3)^3
Step-by-step explanation:
The inverse of a function is found by switching the roles of the dependent and independent variables. In other words, we can find the inverse of a function by interchanging the x and y values in the equation. So, the inverse of the function f(x) = 2(x-2)^2 + 1 can be written as f^-1(x) = 2(x-2)^2 + 1.
1. To find the inverse function explicitly, we can use the following steps:
2. Replace f(x) with y in the original function to obtain y = 2(x-2)^2 + 1.
3. Solve for x in terms of y to obtain x = +/- sqrt((y-1)/2) + 2.
The inverse function f^-1(x) can then be written as f^-1(x) = +/- sqrt((x-1)/2) + 2.
Note that this inverse function is not a one-to-one function, because for some values of x (namely, x < 1), the function has two possible values of y (i.e. it has two solutions). Therefore, the inverse function is not a function in the strict mathematical sense, but it is still a useful concept in certain contexts.
To find the inverse of a function, we switch the roles of the dependent and independent variables, so the inverse function can be written as x = ^3√y-3.
1. To find the inverse function explicitly, we can use the following steps:
2. Replace y with x in the original function to obtain x = ^3√y-3.
3. Solve for y in terms of x to obtain y = (x+3)^3.
The inverse function can then be written as f^-1(x) = (x+3)^3.
Note that this inverse function is a one-to-one function, meaning that for every value of x, there is only one corresponding value of y. Therefore, the inverse function is a function in the strict mathematical sense.
a population of adult wildebeests in a certain region of africa have weights that are normally distributed with a standard deviation of 579 lbs. how large of a sample is needed to estimate the mean weight to within 135 lbs with a 99% confidence level?
Answers
Sample size 123 is needed to estimate the mean weight to within 135 lbs with a 99% confidence level
What is confidence interval?
In statistics, the probability that a population parameter will fall between a set of values for a predetermined percentage of the time is referred to as the confidence interval. Analysts frequently employ confidence ranges that include 95% or 99% of anticipated observations.
Z(α/2) at 99% confidence level = 2.576
λ = 579
margin of error = ( Z(α/2) * λ ) / √n = 135
(2.576 * 579) / √n = 135
On simplifying, n ≈ 123
So, sample size 123 is needed to estimate the mean weight to within 135 lbs with a 99% confidence level

What is an equation of the line that passes through the point (2,-5) and is parallel to the line x-2y=16
Answers
Answer: y=1/2(x)-6=0.5x-6
Step-by-step explanation: y=mx+c is the general equation of a straight line.
We are told that the line passes through the point (2, -5) this means at x=2 and y=-5
We need to substitute these into the general equation. This gives us the following:
y=mx+c
-5=m*2+c
To solve for c where the graph cuts the y -axis we need to -2m from both sides
-5-2m=2m-2m+c
-5-2m=c
Places this back into the general equation of a straight line gives us the following
y=mx-5-2m
this is the same as
y=m(x-2)-5........we take out a common factor of m
Now we want the above line to be parallel to x-2y=16
To see this we must put the above equation into the form y=mx+c
x-2y=16
We need to make y the subject that is solve for y or have y on its own
To get y term on its own we need to subtract x from both sides
x-x-2y=16-x
-2y=16-x
To finally get y on its own we need to divide both sides by -2
-2y/-2=16/-2 -x/-2
y=-8+x/2
y=x/2-8
this is the same as
y=1/2(x)-8
Therefore m=1/2
we now substitute this back into the previous original equation to get the following
y=1/2(x-2)-5
y=1/2(x)-1-5
y=1/2(x)-6

Who is correct? Try it out with a piece of paper and then use the calculations on the next page to compare.
Answers
The cylinder made with a paper size of 8.5 inches by 11 inches is having more volume and thus contains more chocolate, so, the statement by Oliver is wrong.
What is cylinder?
A cylinder is a three-dimensional solid that maintains two parallel bases spaced at a set distance from one another. These bases often have a circular form (like a circle).
Given:
The size of the first paper = 8.5 inches by 11 inches,
The size of the second paper = 11 inches by 8 inches,
The width of the paper when folded becomes the circumference of the cylinder circle, so,
Circumference of the cylinder for the first case = 2 × π × r
11 = 2 × π × r,
r = 1.75 inches,
The volume of the cylinder for the first case = π × r² × h
The volume of the cylinder for the first case = π × (1.75)² × 8.5
The volume of the cylinder for the first case = 81.78 inches³
Calculate the volume for the second case,
Circumference of the cylinder for the second case = 2 × π × r,
8.5 = 2 × π × r
r = 1.35 inches
The volume of the cylinder for the second case = π × (1.35)² × 11
The volume of the cylinder for the first case = 63.24 inches³
As we know, the cylinder with a higher volume contains more chocolate.

The total number of cans collected is calculated as
Cans collected = Mr. Juarez + Ms. Wade
Substitute the known values in the above equation, so, we have the following representation
Cans collected = 8n - 7 + 6n + 3
Evaluate the like terms
Cans collected = 14n - 4

Answers
In linear equation, The amount of butter used is an illustration of equivalent ratio.
The amount of butter used last month is 300kg.
What is a linear equation?
A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.
The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
Because the bakery used 25% more last month, the amount they used is then calculated using
Amount = ( 1 + 25%) * last month
Substitute 240kg for Last Month
Amount = ( 1 + 0.25) * 240

Amount = 1.25 * 240kg

Mikaela purchased a paddleboard originally priced at $699. If all merchandise was on sale for 40% off and the state tax rate is 7. 25%, what is the total amount that mikaela spent on the paddleboard?.
Answers
The total amount that Mikaela spent on the paddleboard will be $449.80.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths.
As per the given,
Original price = $699
The selling price = $699 - 40% of $699
⇒ $699 - 0.40 x $699 = $419.4
The state tax (assuming it applied to the selling price) will be as,
7.25% of $419.4 = (7.25/100) x 419.4 = $30.4065
Final amount = $419.4 + $30.4065 = $449.80
