Answer:
c on edge
Step-by-step explanation:
just took the quiz
The equation representing the circle A is (x – 4)² + (y + 5)² = 36.
What is circle?A circle is a spherical shape without boundaries or edges. A circle is a closed, curved object with two dimensions in geometry.
The general equation of circle is given by equation
( x - h )² + ( y - k )² = r²
Where, ( h, k ) is the centre and 'r' is the radius.
As, the circle has a shift of 4 units on the +x axis.
The circle has a shift of the 5 units on the -y axis.
As, the circle has a radius of 6 units from the graph.
So, (h,k) = (4, -5).
Substitute the values of (h,k) in the general equation of the circle.
( x - 4 )² + ( y - (-5) )² = 6²
( x - 4 )² + ( y + 5 )² = 36
Therefore, the equation of circle becomes ( x - 4 )² + ( y + 5 )² = 36.

Answer:
x = 20°
Step-by-step explanation:
For questions like this, it is helpful to remember that an exterior angle is equal to the sum of the remote interior angles.
110° = 2x + 70°
40° = 2x
20° = x
_____
Similarly, ...
y = x + 70° = 20° +70°

Work out the value of the missing angle x
Answer:
The value of the missing angle, x° is 115°
Step-by-step explanation:
The sum of the interior angles in a polygon is given by the formula (n - 2)×180, where, 'n', is the number of sides in the polygon
The number of sides in the given polygon, n = 10 sides
Therefore;
The sum of the interior angles in the polygon is (10 - 2)×180 = 1440°
The given angles of the polygon are;
107°, 126°, 325°, 125°, 95°, x°, 90°, 280°, 47°, and 130°
Therefore, we have;
107° + 126° + 325° + 125° + 95° + x° + 90° + 280° + 47° + 130° = 1440°
x° = 1440° - (107° + 126° + 325° + 125° + 95° + 90° + 280° + 47° + 130°) = 115°
The value of the missing angle, x° = 115°.
3/5a-1/2a=9/2
please help solve
for a and show work !!
Answer:
a = 45
Step-by-step explanation:
Start by changing the fractions so they share a common denominator to combine like-terms:
6/10a - 5/10a = 9/2
1/10a = 9/2
Multiply both sides by 10 to isolate a.
a = 90/2
a = 45
Prove that if x is an positive real number such that x + x^-1 is an integer, then x^3 + x^-3 is an integer as well.
Answer:
By closure property of multiplication and addition of integers,
If [tex]x + \dfrac{1}{x}[/tex] is an integer
∴ [tex]\left ( x + \dfrac{1}{x} \right) ^3 = x^3 + \dfrac{1}{x^3} +3\cdot \left (x + \dfrac{1}{x} \right )[/tex] is an integer
From which we have;
[tex]x^3 + \dfrac{1}{x^3}[/tex] is an integer
Step-by-step explanation:
The given expression for the positive integer is x + x⁻¹
The given expression can be written as follows;
[tex]x + \dfrac{1}{x}[/tex]
By finding the given expression raised to the power 3, sing Wolfram Alpha online, we we have;
[tex]\left ( x + \dfrac{1}{x} \right) ^3 = x^3 + \dfrac{1}{x^3} +3\cdot x + \dfrac{3}{x}[/tex]
By simplification of the cube of the given integer expressions, we have;
[tex]\left ( x + \dfrac{1}{x} \right) ^3 = x^3 + \dfrac{1}{x^3} +3\cdot \left (x + \dfrac{1}{x} \right )[/tex]
Therefore, we have;
[tex]\left ( x + \dfrac{1}{x} \right) ^3 - 3\cdot \left (x + \dfrac{1}{x} \right )= x^3 + \dfrac{1}{x^3}[/tex]
By rearranging, we get;
[tex]x^3 + \dfrac{1}{x^3} = \left ( x + \dfrac{1}{x} \right) ^3 - 3\cdot \left (x + \dfrac{1}{x} \right )[/tex]
Given that [tex]x + \dfrac{1}{x}[/tex] is an integer, from the closure property, the product of two integers is always an integer, we have;
[tex]\left ( x + \dfrac{1}{x} \right) ^3[/tex] is an integer and [tex]3\cdot \left (x + \dfrac{1}{x} \right )[/tex] is also an integer
Similarly the sum of two integers is always an integer, we have;
[tex]\left ( x + \dfrac{1}{x} \right) ^3 + \left(- 3\cdot \left (x + \dfrac{1}{x} \right ) \right )[/tex] is an integer
[tex]\therefore x^3 + \dfrac{1}{x^3} = \left ( x + \dfrac{1}{x} \right) ^3 - 3\cdot \left (x + \dfrac{1}{x} \right )= \left ( x + \dfrac{1}{x} \right) ^3 + \left(- 3\cdot \left (x + \dfrac{1}{x} \right ) \right )[/tex] is an integer
From which we have;
[tex]x^3 + \dfrac{1}{x^3}[/tex] is an integer.

Suppose a line parallel to side BC of ABC intersects sides AB and AC at points X and Y, respectively. Find the length of AC if AX=3, XB=4, and AY=1.5.
AC=2
AC=4
AC=2.5
AC=3.5
Answer: AC=3.5
Solve proportionally:3 over 4 equals 1.5 over x.
3x= 6
6/3=2
X=2
2+1.5=3.5
Suppose a line parallel to side BC of ABC intersects sides AB and AC at points X and Y, respectively. Than the length of AC will be 3.5.So,The answer is AC=3.5 Given: AX = 3 ,XB = 4, AY = 1.5
To find: AC
Since line XY is parallel to BC, then AX/XB = AY/YC
Substitute the given values: 3/4 = 1.5/YC
Solve for YC: YC = 6/5
AC = YC + AY = 6/5 + 1.5 = 3.5
Therefore, the length of AC is 3.5.

Josh was able to type 496 words in 8 minutes. How many words can he type in 35 minutes?
Answer:
2170 words
Step-by-step explanation:
If we are assuming words and minutes are directly proportional to each other, we can say that w (words) = k (constant variable) x t (time in mins).
NOTE: directly proportional means that as one variable increases, the other variable increases too (or if one decreases, the other also decreases).K is the constant variable, which we must work out to find out any other time. If you rearrange the formula, it shows that k can be calculated by doing w/t. We have a set of values we can use to calculate k which are given in the question. So if we use this formula to calculate k, then:
k= w/t
k= 496/8
k= 62
Now we know the constant variable is 62. So, we go back to our equation but now we must find how many words. We now have our k value and our value for t. So, now we substitute:
w=kt
w= 62 x 35
w= 2170
