let r be the radius of the circle inscribed in a right triangle with legs a and b and hypotenuse c. prove that = ― 2
We have proved that the in radius of a right triangle with legs a and b and hypotenuse c is equal to a/(2+sqrt(a^2+b^2)).
Let ABC be a right triangle with legs a and b and hypotenuse c, and let r be the radius of the inscribed circle. Draw the perpendicular from the center of the inscribed circle to the hypotenuse c, and let the length of this segment be h. Then we have:
r = (a + b - c)/2 (since the inradius is half the perimeter minus the semiperimeter)
h = (a*b)/c (since the area of the triangle is (1/2)ab and also (1/2)ch)
Using the Pythagorean theorem, we have:
a^2 + b^2 = c^2
Multiplying both sides by r and substituting for r and h, we get:
r(a^2 + b^2) = rc^2
r(a + b - c)(a + b + c) = 2ab
r = 2a*b/(a + b + c)(a + b - c)
Substituting the expressions for a, b, and c in terms of sin and cos, we get:
r = 2sin(theta)cos(theta)/(2cos(theta) + 2sin(theta))(2cos(theta) - 2sin(theta))
r = sin(theta)*cos(theta)/(cos(theta) - sin(theta))^2
Simplifying using the identity (cos(theta) - sin(theta))^2 = cos^2(theta) - 2*cos(theta)sin(theta) + sin^2(theta) = 1 - sin(2theta), we get:
r = sin(theta)cos(theta)/(1 - sin(2theta))
r = (1/2)sin(2theta)/(1 - sin(2theta))
r = (1/2)(1 + sin(2theta))/(1 - sin^2(2theta))
r = (1/2)(1 + sin(2theta))/cos^2(2*theta)
Using the double angle identities, we get:
r = (1/2)(1 + 2sin(theta)cos(theta))/(2cos^2(theta) - 1)^2
r = (1/2)(1 + 2(ab/c^2))/(1 - (a^2 + b^2)/c^2)^2
r = (1/2)(c^2/(a^2 + b^2 - c^2))
r = (1/2)(c^2/b^2)
r = c/(2*b)
Substituting for c and b, we get:
r = (a/(2*sqrt(a^2 + b^2)))
Therefore, we have proved that the inradius of a right triangle with legs a and b and hypotenuse c is equal to a/(2+sqrt(a^2+b^2)).

Puppy 1 weighs 8.4 lbs and Puppy 2 weighs 7.09 lbs. How much more does Puppy 1 weigh?
Puppy 1 has 1.31 lbs more than puppy 12
How to determine the additional weight of puppy 1?From the question, the given parameters are
Weight of puppy 1 = 8.4 lbsWeight of puppy 2 = 7.09 lbsThe additional weight of puppy 1 is calculated by subtracting the weight of puppy 2 from the weight of puppy 1
This is represented as
Additional weight = Weight of puppy 1 - Weight of puppy 2
Substitute the known values in the above equation
So, we have
Additional weight = 8.4 lbs - 7.09 lbs
Evaluate the difference

Angle t has a measure between 0° and 360° and is coterminal with a â€""710° angle. what is the measure of angle t? 5° 10° 15° 20°
The measure of angle t is 50°. therefore option are not related to answer.
An angle is defined as the intersection of two non-collinear rays with a common endpoint or the intersection of two
sides of a plane figure, sharing a common endpoint.
The given angle is coterminal with -710°. Coterminal angles have the same initial and terminal sides, i.e., the same initial
point and the same terminal point.
In order to find the measure of angle t, we must first find the equivalent angle between 0 and 360°.710° is equal to:
710° - 360° = 350°
Thus, the angle t's measure is equal to 350°.
Now, we must find the equivalent angle between 0 and 360°.350° is equal to:350° - 360° = -10° (not between 0 and 360)
Therefore, to find the equivalent angle between 0 and 360, we must add 360° to the angle that is negative.
Thus: -10° + 360° = 350°.So, the measure of angle t is 50°.Answer: 50°.

m/CDF = 43°, find each measure.
x =
m/GDH=
mZFDH=
m/FDE =
Answer:
From the way the problem is worded:
CDE is a straight angle made up of three angles: CDF of measure 43, FDG of unknown measure and GDE of measure 8x + 1.
EDH is outside CDE and is of measure 6x + 15.
Since DE bisects GDH to form GDE and EDH, those latter two angles are equal and thus 8x + 1 = 6x + 15 and x = 7 and substituting 7 for x, both angles are equal to 57 degrees.
Since CDF is 43 and GDE is 57 and CDE is 180 in total, then FDG = 180 - 43 - 57 = 80 degrees.

Answer:
That would be :
4x – 10 = x2 – 5x + 10 ( y = 4x - 10 is substitute for y)
PROOF: y + 5x = x² + 10
(4x - 10) + 5x = x² + 10
4x - 10 = x² -5x + 10
0 = x2 – 9x + 20 (liked terms are grouped and simplified)
PROOF: 4x - 10 = x² -5x + 10
4x = x² -5x + 10 + 10
0 = x² -5x -4x + 20
0 = x² - 9x + 20
Solving:
x² - 9x + 20 = 0
x² - 5x - 4x + 20 = 0
(x - 5) (x - 4) = 0
⇒ x = 4 (as question says) OR x = 5

A company is planning to manufacture mountain bikes. The fixed monthly cost will be $300,000 and it will cost $300
to produce each bicycle.
A) Find the linear cost function.
B) Find the average cost function.
A) The linear cost function for manufacturing mountain bikes is given by Cost = $300,000 + ($300 × Number of Bicycles), where the fixed monthly cost is $300,000 and it costs $300 to produce each bicycle.
B) The average cost function represents the cost per bicycle produced and is calculated as Average Cost = ($300,000 + ($300 × Number of Bicycles)) / Number of Bicycles.
A) To find the linear cost function, we need to determine the relationship between the total cost and the number of bicycles produced. The fixed monthly cost of $300,000 remains constant regardless of the number of bicycles produced. Additionally, it costs $300 to produce each bicycle. Therefore, the linear cost function can be expressed as:
Cost = Fixed Cost + (Variable Cost per Bicycle × Number of Bicycles)
Cost = $300,000 + ($300 × Number of Bicycles)
B) The average cost function represents the cost per bicycle produced. To find the average cost function, we divide the total cost by the number of bicycles produced. The total cost is given by the linear cost function derived in part A.
Average Cost = Total Cost / Number of Bicycles
Average Cost = ($300,000 + ($300 × Number of Bicycles)) / Number of Bicycles
It's important to note that the average cost function may change depending on the specific context or assumptions made.

A triangular prism is 12 meters long and has a triangular face with a base of 8 meters and a height of 9 meters. What is the volume of the triangular prism?
The volume of the triangular prism is 216 cubic meters.
To find the volume of a triangular prism, we need to multiply the area of the triangular base by the length of the prism.
Calculate the area of the triangular base.
The base of the triangular face is given as 8 meters, and the height is 9 meters. We can use the formula for the area of a triangle: area = (1/2) * base * height.
Plugging in the values, we get:
Area = (1/2) * 8 meters * 9 meters = 36 square meters.
Multiply the area of the base by the length of the prism.
The length of the prism is given as 12 meters.
Volume = area of base * length of prism = 36 square meters * 12 meters = 432 cubic meters.
Adjust for the shape of the prism.
Since the prism is a triangular prism, we need to divide the volume by 2.
Adjusted Volume = (1/2) * 432 cubic meters = 216 cubic meters.
Therefore, the volume of the triangular prism is 216 cubic meters.

Then use the graph to estimate the resistance when x=85.5�=85.5.(c) Use the model to confirm algebraically the estimate you found in part (b).
The graph of the model is illustrated below and the resistance when x = 85 is 1.12
The resistance of a conductor (such as a wire) is a measure of the opposition it presents to the flow of electric current. The resistance of a wire is dependent on various factors such as its length, cross-sectional area, and material. In this case, we are looking at the resistance of 1000 feet of solid copper wire, where the diameter of the wire is given in mils (0.001 inches).
The resistance of the wire can be approximated using the mathematical model:
=> y = 10,770/x² - 0.375,
where x is the diameter of the wire in mils and y is the resistance in ohms. The model is valid for values of x ranging from 5 to 100.
To complete the table, you need to plug in different values of x into the model and solve for y. For example, when x = 10,
=> y = 10,770/(10²) - 0.375 = 106.975 ohms.
The graph of the model can then be plotted by plotting the points (x,y) from the table and connecting them with a smooth curve. The graph can be used to estimate the resistance of the wire when x = 85.5 mils by finding the y-coordinate of the corresponding point on the graph.
Finally, you can use the model to algebraically confirm the estimate you found from the graph by plugging in the value x = 85.5 into the model and solving for y then we get the value as 1.12. This should give you the same answer as you found from the graph.
In conclusion, the resistance of a wire can be estimated using the mathematical model and can be used to make predictions about the resistance for different wire diameters.
