Consider the sets below.
A {x|x is a polygon}
B {x|x is a triangle}
Which is true?
A ⊂ B
B ⊂ A
Ac = B
Bc = A
Answer:
B ⊂ A
Step-by-step explanation:
We know that:
A {x|x is a polygon}
So set A is the set of all polygons.
B {x|x is a triangle}
Set B is the set of all triangles.
First, a polygon is a plane geometrical figure made of a finite sequence of straight segments.
For example, a triangle is a polygon, a rectangle is a polygon, etc.
Then, all triangles are polygons, but not all polygons are triangles.
So we can conclude that the whole set B is included in the set A.
Then the correct notation would be:
B ⊂ A
Answer:
B ⊂ A

Solve the quadratic equation below: 4x^2 -100=0
Answer:
solution given:
4x^2 -100=0
4x²=10²
(2x)²=10²so
2x=±10
x=±10/2
so
x=5
or x=-5
Answer:
The answer is x=-5

The equation of the line that goes through the points ( − 3 , − 9 ) and ( − 6 , − 3 ) can be written in the form y = m x + b
Answer:
[tex]y=-2x-15[/tex]
Step-by-step explanation:
[tex]y=mx+b[/tex].
m is the slope of the line. To find it we can do [tex]\frac{dy}{dx}[/tex] which is the difference between the y-coordinates divided by the difference between the x-coordinates.
So: [tex]\frac{dy}{dx} =\frac{-9-(-3)}{-3-(-6)} =\frac{-6}{3} =-2[/tex]. Now we have the slope, let's input a set of coordinates into the equation so that we can find the constant [tex]b[/tex].
[tex]-9=-2(-3)+b[/tex]
[tex]b=-15[/tex] - Re-arranging to get b
Now re-write the equation as we have the constants.
[tex]y=-2x-15[/tex]
Find x
Secant tangent angles
Answer:
148 = x
Step-by-step explanation:
Using the Secant and Tangent Intersection theorem we can say;
38 = 1/2 (x - 72)
38 = 1/2x - 36
74 = 1/2x
(74)/(1/2) = x
148 = x

The freezing point of neon is about -249c . The freezing point of chorine is about 148c higher. What is the approximate freezing point of chlorine?
Answer:
-101 c.
Step-by-step explanation:
-249 + 148
= -(249 - 148)
= -101 C.
The approximate freezing point of chlorine is -101°C.
We have,
The freezing point of neon is about -249c .
The freezing point of chorine is about 148c higher.
To find the approximate freezing point of chlorine, we add 148°C to the freezing point of neon:
= -249°C + 148°C
= -101°C
Therefore, the approximate freezing point of chlorine is -101°C.
