Step-by-step explanation:
a rectangle has two pairs of equally long sides and each of the 4 angles between the sides is 90 degrees.
given that ABCDEF is a regular hexagon, it means that all its sides are equally long, and therefore also all internal angles are the same size.
that means for ACDF that the sides DC and FA are equally long.
DEF and ABC are congruent triangles, as the sides DE = BC, EF = AB, and the angle E is congruent to angle B.
based on the SAS criteria this confirms that DF is congruent to AC.
the angles ACB, CAB, EDF and EFD have to be all the same, and therefore also the angles FDC, DCA, CAF and DFA.
so, all 4 angles of the parallelogram ACDF are the same, and the sum of all these angles has to be 360 degrees, we have
360 = 4×angle
angle = 90 degree.
so, all angles are 90 degrees and we have two pairs of equally long sides : this process that ACDF us a rectangle

Mrs. Helton is making gift bags as prizes for her math classes. She has 30 little bags of Hershey Kisses and 15 Blow Pops. What is the greatest number of gift bags she can make if all gift bags are the same, and she does not want any left over?
Answer:
15
Step-by-step explanation:
For this we must find the GCF, or greatest common factor, because we cannot have multiples.
Factors of 30:
1 , 2, 3, 5, 6, 10, 15, 30
Factors of 15:
1, 3, 5, 15
GCF = 15
Each bag will have 2 Hershey bags, and 1 Blow Pop

C. 2√3 over 3
D. 3
Answer:
A, 3 root 3
Step-by-step explanation:
The triangle is a 30-60-90 Triangle meaning that the shortest side can be multiplied by 2 to get the hypotenuse or the slanted/longest side.
The second longest side of this triangle will always be the shortest side times root 3. Use the chart as a reference.
Answer:
3√3
Step-by-step explanation:
Angle ratio = 30 : 60 : 90
Side ratio = a : a√3 = 2a
Side opposite to 90° = 2a
2a = 6
a = 6/2
a = 3
Side opposite to 60° = a√3
x = a√3 =3√3

1.Given the function f(x) = -2c + cx - x^2? and f^-1(5) = -1, find c
Here we have a quadratic function and we want to find the value of a constant with a given restriction.
We will find that c = 8.
So we have the function:
[tex]f(x) = -2c + cx - x^2[/tex]
We know that:
[tex]f(5)^{-1} = -1 = \frac{1}{-2c + c\cdot 5 - (5)^2}[/tex]
Notice that the above equation means that:
[tex]-2c + c\cdot5 - (5)^2 = -1[/tex]
Then we just need to solve the above equation for c:
[tex]-2c + 5c - (5)^2 = -1\\\\(-2 + 5)\cdot c - 25 = -1\\\\3\cdot c = -1 + 25\\\\3\cdot c = 24\\\\c = 24/3 = 8[/tex]
So we found that the value of c is 8.
This means that the function is:
[tex]f(x) = -16 + 8\cdot x - x^2[/tex]

Which plane geometry has countless symmetry axis ? (except for circle)
Sorry if there are some grammatical mistakes in my question because English isn't my first language. Thank you very much !
Countless symmetry axis of a parabola is vertical line which divides the parabola into two congruent halves.
The axis of symmetry always passes through vertex of parabola. These will cause the plane to divide into two parts.
The geometric shape may have countless symmetry axis. This actually divides the shape into two halves and creates a mirror like effect.
The x-coordinate of vertex is equation of axis symmetry of parabola. Lets say if we take an example of quadratic equation which is ,
y = ax^2 + bx + c , here in this equation the axis of symmetry is vertical line which is x = - b^2 a

Find the slope (-2,5),(2,9)
Answer:
1
Step-by-step explanation:
Let,
x1 = - 2
y1 = 5
x2 = 2
y2 = 9
Formula : -
Slope = ( y2 - y1 ) / ( x2 - x1 )
Slope
= ( 9 - 5 ) ) / ( 2 - ( - 2 )
= 4 / 4
= 1
Answer:
slope is 1
Step-by-step explanation:
from (-2, 5) to (2,9)
slope m= (y2-y1) / (x2-x1) = (9-5) / (2- -2) = 4 / 4 =1
*
you can think of how do you get from one point to the other
first point (-2, 5) go to second point (2,9)
-first on the y-axis (vertical) you start at 5 and go four up to get to 9
-second on the x-axis (horizontal) you start at -2 and go four right to get to 2
slope = change in y / change in x = four up /four right = 4/4 = 1
-moving down or to the left will make the numbers negative
