Sketch the region bounded by the curves, and visually estimate the location of the centroid. (do this on paper. Your instructor may ask you to turn in this work. ) then find the exact coordinates of the centroid. Y = ex y = 0, x = 0, x = 5
The centroid of the region enclosed by y = ex, y = 0, x = 0 and x = 5 is at the point ( (5e^5 - 5) / (e^5 - 1) , (e^10 - 1) / 2(e^5 - 1) ).
To find the centroid of a region, we need to first find the area of the region and the coordinates of the center of mass of the region.
The region enclosed by y = e^x, y = 0, x = 0 and x = 5 can be represented by the definite integral of the function y = ex between the limits of x = 0 and x = 5. The area of this region is given by the definite integral:
∫[0,5] e^x dx
The definite integral of ex is e^x, so the area of the region is e^5 - e^0 = e^5 - 1.
To find the x-coordinate of the centroid, we need to find the integral of
x e^x from 0 to 5, divided by the area.
= ∫[0,5] xe^x dx / (e^5 - 1)
The integral of xe^x is
= (xe^x - ∫e^x dx)
= (xe^x - e^x)
So the x-coordinate of the centroid is
= ∫[0,5] xe^x dx / (e^5 - 1)
= (4e^5 + 1) / (e^5 - 1)
To find the y-coordinate of the centroid we need to find the integral of
ye^x from 0 to 5, divided by the area.
∫[0,5] (e^x * e^x) dx / (e^5 - 1)
∫[0,5] (e^(2x)) dx / (e^5 - 1)
The integral of e^(2x) is (1/2)e^(2x)
So the y-coordinate of the centroid is
∫[0,5] e^(2x) dx / (e^5 - 1) = (1/2) * (e^10 - e^0) / (e^5 - 1)
= (1/2) * (e^10 - 1) / (e^5 - 1)
= (e^10 - 1) / 2(e^5 - 1)
So the centroid of the region enclosed by y = ex, y = 0, x = 0 and x = 5 is at the point ( (5e^5 - 5) / (e^5 - 1) , (e^10 - 1) / 2(e^5 - 1) ).

567 is what percent of 448?
To find out what percent 567 is of 448, we can use the following formula:
What does math mean by percent?
In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).
percent = (part / whole) x 100
where "part" is the value we are trying to find the percentage of (in this case, 567), "whole" is the total value (in this case, 448), and "percent" is the final answer.
So, we can plug in the values and get:
percent = (567 / 448) x 100
To get the percentage we need to multiply the fraction by 100
percent = 126.58%
So 567 is 126.58% of 448.

What do balloon mortgage and ARM have in common?
OA. Both have variable rates.
B. The both automatically adjust after the initial period.
C. Both have fixed initial rate and payment amount.
D. Both have interest rates higher than fixed rate.
Correct option is C, Both have fixed initial rate and payment amount.
A balloon mortgage is similar to an adjustable rate mortgage (ARM) in other ways, with an initial rate period that is equal to the balloon duration. For instance, a 7-year balloon is frequently contrasted with a 7-year ARM. For 7 years, both have a set rate; after that, the rate will change.
A balloon mortgage starts off with set payments for a set amount of time and comes to a finish with a single, large payment. Because it is substantially greater than the initial instalments, the one-time payment is known as a balloon payment. According to the definition of a balloon loan, the final payment is at least twice as much as the average monthly payment on the mortgage. Balloon payments typically cost tens of thousands of dollars.
Variable-rate mortgages (VRMs), commonly referred to as adjustable-rate mortgages (ARMs), feature an interest rate that may fluctuate on a regular basis based on changes in the appropriate financial index linked to the loan. Generally speaking, if the index rate rises or falls, your monthly payment will too.

endpoint at (8, -5). What are the coordinates
of the other endpoint?
The coordinates for the other endpoint of the line segment will be (-4,-9).
What are coordinates of a line segment?
The location of a line segment on the coordinate plane is defined by two endpoints whose coordinates are known. The line links the two endpoints but does not extend beyond them. It is a segment (piece) of a line.
This is the same as the definition of a line segment in ordinary plane geometry, the only difference being that we know the coordinates of the points involved.
Coordinates - Coordinates are the components of an ordered pair. In an ordered pair, the first number is called the x-coordinate and the second number is called the y-coordinate.
Now
Given,
One endpoint (x2,y2) having coordinates= (8,-5)
Let other endpoint be = (x1,y1)
Midpoint (x, y) = (2,-7)
Therefore,
x=(x1+x2)/2 and y=(y1+y2)/2
x1=2x-x2 y1=2y-y2
x1=4-8 y1=-14+5
x1=-4 y1=-9

Answer: _____mi/mins
Answer: _____ mi/hrs
The average speed of the trip will be 1.60 miles/mins and 96.64 miles/hrs.
What is an average?
An average of a list of data is a mathematical expression for the center value of a set of data. It is defined mathematically as the ratio of the total of all the data to the number of units in the list. In statistics, the average of a particular collection of numerical data is also known as the mean.
e.g.
The average of 2, 3, and 4 equals (2+3+4)/3 = 9/3 = 3. As a result, the central value of 2,3, and 4 is 3. Thus, the definition of average is to determine the mean value of a set of data.
Average speed:-
The formula for average speed is found by calculating the ratio of the total distance traveled by the body to the time taken to cover that distance.
average speed = total distance / total time
Now,
As given
Total distance covered = 16+185+145
=346 miles
Total time taken=20 + 120 + 75
=215 minute (3.58 hours)
Average speed=346/215

suppose a midpoint riemann sum with 3 equal subintervals is used to approximate 4 1 (2x2 1) dx. what is the value of this approximation?
The value of this approximation will be 3.7678.
To approximate the integral of 4 1 (2x2 1) dx using a midpoint Riemann sum with 3 equal subintervals, the following calculations can be used:
Start by finding the width of each subinterval (w). Using the given bounds of integration, this can be calculated as: w = (b-a)/n, where n is the number of subintervals. In this case, w = (2-1)/3 = 0.3333.
Next, calculate the midpoint of each subinterval. This can be done by taking the average of the lower and upper bounds of each subinterval. In this case, the midpoints are 1.1667, 1.5, and 1.8333.
Finally, calculate the value of the midpoint Riemann sum by adding the product of the function evaluated at each midpoint and the width of each subinterval. This can be expressed as:
Sum = 0.3333 * [4(1.1667)2 -1] + 0.3333 * [4(1.5)2 -1] + 0.3333 * [4(1.8333)2 -1]

The parameters of the right triangle are;
∠A = 45°
[tex]\overline{AC}[/tex] = 14 km
∠C = 90°
The angle sum property can be used to find the measure of the angle ∠B as follows;
m∠A + m∠B + m∠C = 180° (Angle sum property of a triangle)
45° + m∠B + 90° = 180°
m∠B = 180° - (90° + 45°) = 45°
m∠B = 45°Two angles in the triangle ΔABC are congruent, therefore, the triangle is an isosceles right triangle and the legs, [tex]\overline{AC}[/tex] and [tex]\overline{BC}[/tex] are congruent.
[tex]\overline{AC}[/tex] = [tex]\overline{BC}[/tex] (definition of congruency)
[tex]\overline{BC}[/tex] = [tex]\overline{AC}[/tex] = 14 kilometers
[tex]\overline{BC}[/tex] = 14 kmThe hypotenuse side of the right triangle = [tex]\overline{AB}[/tex]
The legs of the right triangle are; [tex]\overline{AC}[/tex] and [tex]\overline{BC}[/tex]
Pythagorean Theorem, states that we get;
[tex]\overline{AB}[/tex]² = [tex]\overline{AC}[/tex]² + [tex]\overline{BC}[/tex]²Therefore;
[tex]\overline{AB}[/tex]² = 14² + 14² = 14² × (1 + 1) = 14² × 2
[tex]\overline{AB}[/tex] = √((14)²×2) = 14·√2
[tex]\overline{AB}[/tex] = 14·√2 kmThe correct option is option c.

Step-by-step explanation:
"Use the equation to make a prediction about the temperature if the ice is 2 ⅓ inches thick."
Equation: y= -3
The temperature of the ice when it is 2 ⅓ inches thick is - 7 degrees Fahrenheit
How to find the temperature ?The equation y = -3 x means that the temperature of the ice is directly related to the thickness of the ice.
Given the thickness of the ice, the temperature of the ice would be negative three times the temperature.
This means that when the thickness is 2 ⅓ inches thick, then the temperature is:
y = - 3 x
y = - 3 x 2 ⅓ inches
y = - 7 degrees Fahrenheit

Answer: [tex]\sqrt{41}[/tex]
Step-by-step explanation:
Using the distance formula: D = √(2 - 7)2 + (-6 - -2)2
= √(-5)2 + (-4)2
= √41
[tex]~~~~~~~~~~~~\textit{distance between 2 points} \\\\ M(\stackrel{x_1}{7}~,~\stackrel{y_1}{-2})\qquad A(\stackrel{x_2}{2}~,~\stackrel{y_2}{-6})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ MA=\sqrt{(~~2 - 7~~)^2 + (~~-6 - (-2)~~)^2} \implies MA=\sqrt{(2 -7)^2 + (-6 +2)^2} \\\\\\ MA=\sqrt{( -5 )^2 + ( -4 )^2} \implies MA=\sqrt{ 25 + 16 } \implies MA=\sqrt{ 41 }[/tex]
mind you that the distance equation comes directly from the pythagorean theorem.

The scale factor when AABC is a dilation of ADEF with center (0, 0) is 1/3.
What is scale factor?A scale factor is a number that scales, or multiplies, some quantity. In the context of geometry, a scale factor is a ratio that describes how the dimensions of one geometric figure are related to the dimensions of another similar figure. Similarly, if a two-dimensional shape is scaled up or down by a factor of k, then all of its linear dimensions (such as length, width, and height) are multiplied by k, and its area is multiplied by k².
