What is the relationship between the measure of angle and the reflex measure of the angle
Answers
Angles are measured in degrees and their reflex measures can be obtained by adding 180 degrees to their measures.
In mathematics, an angle is a measure of the amount of turn between two lines or rays that share a common endpoint. The measure of an angle is given in degrees, and it represents the amount of rotation needed to move from one ray to the other.
The reflex measure of an angle is the sum of the angle's measure and 180 degrees. It represents the amount of rotation needed to move from one ray to the other while going in the opposite direction. For example, if an angle has a measure of 30 degrees, its reflex measure would be 30 degrees + 180 degrees = 210 degrees.
So, the relationship between the measure of an angle and its reflex measure is that the reflex measure is obtained by adding 180 degrees to the measure of the angle.

find the equation of the circle where (-9,4),(-2,5),(-8,-3),(-1,-2) are the vertices of an inscribed square.
Answers
so... hmm the diagonals for the square are the diameter of the circle, and keep in mind that the radius of a circle is half the diameter, so let's find the diameter.
[tex]\bf \textit{distance between 2 points}\\ \quad \\ \begin{array}{lllll} &x_1&y_1&x_2&y_2\\ % (a,b) &({{ -2}}\quad ,&{{ 5}})\quad % (c,d) &({{ -8}}\quad ,&{{ -3}}) \end{array}\qquad % distance value d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2} \\\\\\ \stackrel{diameter}{d}=\sqrt{[-8-(-2)]^2+[-3-5]^2} \\\\\\ d=\sqrt{(-8+2)^2+(-3-5)^2}\implies d=\sqrt{(-6)^2+(-8)^2} \\\\\\ d=\sqrt{36+64}\implies d=\sqrt{100}\implies d=10[/tex]
that means the radius r = 5.
now, what's the center? well, the Midpoint of the diagonals, is really the center of the circle, let's check,
[tex]\bf \textit{middle point of 2 points}\\ \quad \\ \begin{array}{lllll} &x_1&y_1&x_2&y_2\\ % (a,b) &({{ -2}}\quad ,&{{ 5}})\quad % (c,d) &({{ -8}}\quad ,&{{ -3}}) \end{array}\qquad \left(\cfrac{{{ x_2}} + {{ x_1}}}{2}\quad ,\quad \cfrac{{{ y_2}} + {{ y_1}}}{2} \right) \\\\\\ \left( \cfrac{-8-2}{2}~,~\cfrac{-3+5}{2} \right)\implies (-5~,~1)[/tex]
so, now we know the center coordinates and the radius, let's plug them in,
[tex]\bf \textit{equation of a circle}\\\\ (x-{{ h}})^2+(y-{{ k}})^2={{ r}}^2 \qquad \begin{array}{lllll} center\ (&{{ h}},&{{ k}})\qquad radius=&{{ r}}\\ &-5&1&5 \end{array} \\\\\\\ [x-(-5)]^2-[y-1]^2=5^2\implies (x+5)^2-(y-1)^2=25[/tex]
The equation of the circle where the vertices of an inscribed square are (-9,4),(-2,5),(-8,-3),(-1,-2) is (x+5)² + (y-1)² = 25. This is found by getting the average x and y coordinates to find the center of the circle, calculating the radius, and applying it to the standard equation of a circle.
Explanation:To find the equation of the circle where the vertices of an inscribed square are located at (-9,4),(-2,5),(-8,-3),(-1,-2), first, you need to find the center of the circle. In the case of a square inscribed in a circle, the center of the square is the same as the center of the circle. This can be found by averaging the x and y coordinates of the vertices of the square.
The average x-coordinate = [(-9) + (-2) + (-8) + (-1)] / 4 = -5
The average y-coordinate = [4 + 5 - 3 - 2] / 4 = 1
So, the center of the circle is at (-5, 1).
Next, you need to calculate the radius of the circle. The radius in an inscribed square is the half of the square's diagonal. Calculate the distance between two opposite vertices of the square - for example (-9,4) and (-1,-2). Apply the distance formula: √[(-1 - (-9))^2 + (-2 - 4)^2 ]. That's √[64 + 36], giving a distance of √100 = 10. As this is the diagonal of the square, the radius would be half of this, giving us a radius of 5.
Finally, the equation of the circle in its standard form (x-h)² + (y-k)² = r² can be written as (x+5)² + (y-1)² = 5².
Thus, the equation of the circle is (x+5)² + (y-1)² = 25.

A man has 24 coins in his pocket, all of which are dimes and quarters. If the total value of his change is 345 cents, how many dimes and how many quarters does he have?
Answers
The man has 17 dimes and 7 quarters.
A system of equations was set up, using the total number of coins and their total value, to determine the quantity of each coin type.
Let's denote the number of dimes as d and the number of quarters as q. We are given two facts: (1) the man has a total of 24 coins, and (2) the total value of the coins is 345 cents. Thus we have two equations:
d + q = 24 (since the total number of coins is 24)10d + 25q = 345 (since the value of each dime is 10 cents and each quarter is 25 cents, and their total value is 345 cents)We can solve this system of equations to find the values of d and q.
Subtracting the first equation from the second (multiplied by 10) to eliminate the variable d:
10d + 25q = 345
-(10d + 10q = 240)
-------------------------
15q = 105
Dividing by 15 to solve for q, we get q = 7. This means the man has 7 quarters. Substituting q = 7 into the first equation:
d + 7 = 24
d = 24 - 7
d = 17
So, the man has 17 dimes.
Therefore, the man has 17 dimes and 7 quarters.

Done!
The solution to the equation 4−(2x+4)=5 is x = -2.5. None of the provided suggestions x = 32, x = -52, x = -10, x = 6 are correct.
Explanation:To solve for x in the equation 4−(2x+4)=5, you first simplify the expression in the parentheses, which creates the equation 4 - 2x - 4 = 5. This simplifies to -2x = 5. You then divide each side by -2 which results in x = -5/2 or x = -2.5. So the solution to this equation is not any of the provided x = 32, x = -52, x = -10, x = 6 but rather x = -2.5.

[tex]\frac{6253}{50} million[/tex]
125,060,000
125 million 60 thousand
Step-by-step explanation:
It does not matter how many zeroes we add to the right end after the decimal, it does not change the value of the number.
Thus, 125.06, 125.060, 125.0600,.... all have the same values.
Similarly 125.06 can be change into the rational form
Thus, [tex]125.06=\frac{6253}{50} =\frac{12506}{100} \text{all have same values}[/tex]

Thus, 125.06 million = 125,060,000 = 125 million 60 thousand
f(t)=10t2+5t+1 . Find the value of t for which the tangent line to the graph of f(t) has slope 1.
Answers
The value of t for which the tangent line to the graph of f(t) has slope 1 is -1/5.
The given function is f(t)=10t²+5t+1.
We need to find the value of t for which the tangent line to the graph of f(t) has slope 1.
What is the tangent line to the graph?In geometry, the tangent line (or simply tangent) to a plane curve at a given point is the straight line that "just touches" the curve at that point. Leibniz defined it as the line through a pair of infinitely close points on the curve.
Now, f'(t) = slope of the tangent line to the curve at the point (t, f(t)).
Given, f'(t) = 1
f(t)=10t²+5t+1
⇒f'(t)=20t+5
⇒1=20t+5
⇒20t=-4
⇒t=-4/20
⇒t=-1/5
Therefore, the value of t for which the tangent line to the graph of f(t) has slope 1 is -1/5.

Jordan and Manuel are on the track and field team at school.running around the track one day, Jordan ran 444m and Manuel ran 777 m. They both ran an even number of times around the track. How far is the track
Answers
Answer:
The track is 111 m
Step-by-step explanation:
The easiest way to calculate the meters in the track is to find the Greatest Common Divisor (GCD). This method is used to find the largest number to exactly divide both numbers 444 and 777, which are the meters both guys ran. The resulting number will give us the longest distance the track could have.
There are various techniques used to find the GCD. One of the is to find all divisors of both numbers and then look for the biggest one they have in common.
D 444 = { 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444 }
D 777 = { 1, 3, 7, 21, 37, 111, 259, 777 }
As we can see, the only divisors they have in common are 1, 3 ,37 and 111. The greatest of them is 111 ----> GCD(444,777) = 111.
This means the track has 111 m.
(Actually, the track could have been as long as any of the other common divisors, but it wouldn't have been realistic for the track to be 1, 3 or 37 meters).
