The length of the sides of triangle ABC are: 6, 8, and 12.
One of the conditions that two triangles are similar is their Three pairs of corresponding sides are proportional.
In the given problem, the ratio of the sides of triangle ABC is 3 : 4 : 6
Another triangle, let's say triangle DEF, is made with its vertices at midpoints of the sides of triangle ABC.
Hence, all three pairs of corresponding sides have the same proportion.
AB/DE = BC/EF = AC/DF = 1/2
Due to similarity, the ratio of the sides of triangle DEF is also 3 : 4 : 6.
ratio f sides : perimeter = 3 : 4 : 6 : 13
Since its perimeter is 13, it means that the length of sides of triangle DEF are: 3, 4, and 6
Length of the sides of triangle ABC = 2 x length of the sides of Δ DEF
Length of the sides of triangle ABC are: 6, 8, and 12.

For each figure below, determine if it has rotational symmetry.
If it does, give the smallest angle of rotation needed for the figure to appear unmoved.
A figure has rotational symmetry when it can be rotated by an angle measure which is greater than 0º and less than 360º and the rotated image is equals to the original figure, that is, the image is equals to the pre-image.
A square is divided into four congruent sides, hence it has rotational symmetry, while the unit circle, over which the figures are rotated, is of 360º, hence the angle is given as follows:
360/4 = 90º.
The second figure has three equal arrows, hence it also has rotational symmetry, with an angle given as follows:
360/3 = 120º.

Write the equation of the line in fully simplified slope-intercept form.
Answer:
y = 4/5x + 8
Step-by-step explanation:
y-intercept = b = 8
Use the points (-10,0) and (0,8) to find the slope (m)
m = (8 - 0)/(0 - (-10)) = 8/10 = 4/5
y = mx + b

2. The rate at which glaciers melt is increasing globally. The Saskatchewan Glacier near Banff has receded 1.5 km in the last 75 years. The Peyto Glacier shown below receded 1320 m from 1923 to 1993. Which glacier had the greater annual rate of melting?
Answer:
Saskatchewan Glacier
Step-by-step explanation:
You want to know the greater rate, 1.5 km in 75 years, or 1320 m between 1923 and 1993.
RatesThe rate of glacier recession is the ratio of distance to time:
Saskatchewan Glacier
(1500 m)/(75 yr) = 20 m/yr
Peyto Glacier
(1320 m)/(1993 -1923 yr) = 1320/70 m/yr ≈ 18.86 m/yr
The Saskatchewan Glacier had a greater annual rate of melting.

A parabola can be drawn given a focus of (-8,6) and a directrix of y=0. Write the equation of the parabola in any form
A parabola with focus of (-8, 6) and a directrix of y = 0. has the equation of the parabola as (x + 5)² = 8 (y - 3)
How to write the equation of parabola with directrix of y = 0 and focus of (-8, 5)Quadratic equation = parabolic equation, when the directrix is at y direction is of the form:
(x - h)² = 4P (y - k)
OR
standard vertex form, y = a(x - h)² + k where a = 1/4p
The focus
F (h, k + p) = (-8, 6)
h = -8
k + p = 6
P in this problem, is the midpoint between the focus and the directrix
P = (6 - 0) / 2 = 3
p = 3
the vertex
v(h, k)
h = -8
k + p = 6, k = 3
v(h, k) = v(-8, 3)
substitution of the values into the equation gives
(x - h)² = 4P (y - k)
(x - (-8))² = 4 * 3 (y - 3)
(x + 5)² = 8 (y - 3)

What is direct variation?When two variables are related in a way that one is a constant multiple of the other, this is referred to as direct variation.
The direct variation is given as follows y ∝ x.
The equation is thus of the form y = kx.
Using the given values in the table:
Consider x=-2 and y= -5

T(3,2) and H(1,-2)
Prove: MATH is a parallelogram
Answer:
If both of the opposite sides are parallel then the quadrilateral is a parallelogram. If the slopes are the same and the constants are different than the lines are parallel.
Step-by-step explanation:
If both of the opposite sides are parallel then the quadrilateral is a parallelogram. If the slopes are the same and the constants are different than the lines are parallel.
(-32) ( 3,2) and side (-5,-2) (1,-2)
(-3, 2) (3,2)
Slope [tex]\frac{2-2}{3- -3}[/tex] = [tex]\frac{0}{6}[/tex] = 0
y-intercept
2 = 0(3) + b
2 = b
Equation
y = 0x + 2
y = 2
(-5,-2) ( 1,-2)
slope [tex]\frac{-2 - -2}{1 - -5}[/tex] = [tex]\frac{0}{6}[/tex] = 0
y-intercept
-2 = 0(1) + b
-2 = b
Equation
y = 0x - 2
y = -2
These sides are parallel because the slope is the same and the y-intercepts are different.
Sides (-3,2) (-5,-2) and (3,2) (1,-2)
(-3,2) (-5,-2)
slope [tex]\frac{-2 -2}{-5 - -3}[/tex] = [tex]\frac{-4}{-2}[/tex] = 2
y-intercept
-2 = (2)(-5) + b
-2 = -10 + b
8 = b
Equation:
y = 2x + 8
(3,2) (1,-2)
slope [tex]\frac{-2-2}{1-3}[/tex] = [tex]\frac{-4}{-2}[/tex] = 2
y-intercept
2 = (2)(3) + b
2 = 6 + b
-4 = b
Equation
y = 2x -4
The sides are parallel because the slopes are the same, but the y-intercept are different.

Quadrilateral MATH with vertices M(-5,-2), A(-3,2), T(3,2) and H(1,-2)Recall properties of a parallelogram:
Opposite sides are parallel, and congruent;Diagonals bisect each-other.Prove that same applies to the given quadrilateral.
1) Opposite sides are: MH & AT and MA & TH.
MH and AT have same y-coordinates and therefore both are horizontal, hence parallel.
Their lengths:
MH = 1 - (-5) = 6 units,AT = 3 - (-3) = 6 units.Same can be proved for MA &TH.
2) Find the midpoint of diagonals MT and AH.
Midpoint of MT:
x = (-5 + 3)/2 = - 2/2 = - 1,y = (-2 + 2)/2 = 0/2 = 0.Midpoint of AH:
x = (-3 + 1)/2 = - 2/2 = - 1,y = (2 - 2)/2 = 0/2 = 0.Both diagonals have same midpoint (-1, 0). This proves that diagonals bisect each-other.
Therefore MATH is a parallelogram.

What is the scale factor of dec to abc decimal form only 
The scale factor from the given similar triangles is 3.5 units.
What are similar triangles?Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.
Given that, triangle ABC and triangle DEC are similar.
DE=6, AB=21, DC=4, EC=2x+3, and BC=13x-1.5.
Since, ΔABC similar to ΔDEC
So, AB/DE =AC/DC =BC/EC
21/6 =13x-1.5/2x+3
7/2 =13x-1.5/2x+3
7(2x+3)=2(13x-1.5)
14x+21=26x-3
26x-14x=21+3
12x=24
x=2
So, EC=2x+3 =7 and BC=13x-1.5 =24.5
Now, AB/DE =BC/EC
21/6=24.5/7=3.5
Therefore, the scale factor is 3.5 units.

The length of the skid marks is 336 feet
How to determine the length of the skid marks?
Since the formula s = √(21d) relates the speed (s) of the car and the length of skid (d).
If the car is traveling at 84 miles per hour, we can determine the length of the skid marks by substituting s = 84 into the formula and then solve for d. That is:
s = √(21d)
84 = √(21d)
84² = 21d
7056 = 21d
21d = 7056
d = 7056/21
d = 336 feet
Thus, length of the skid marks is 336 feet
