An equation is formed of two equal expressions. The equation of the perpendicular bisector is y=(1/3)x.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The equation of the line that passes through (2, 4), (3, 1), and (4,-2), are,
m = (4-1)/(2-3) = 3/-1 = -3
Since the product of the slope of two perpendicular lines is -1. The slope of the perpendicular line is,
m₁m₂ = -1
(-3) m₂ = -1
m₂ = 1/3
Since the line is the perpendicular bisector it will pass through midpoint,
1 = (1/3)(3) + C
1 = 1 + C
C = 0
Hence, the equation of the perpendicular bisector is y=(1/3)x.

Using the information in the diagram, what is the height of the tree to the nearest foot?
45 ft
54 ft
60 ft
135 ft
The relationship between the corresponding sides of similar triangles indicates that the height of the tree is 60 feet. The correct option is therefore;
60 ftWhat are similar triangles?Similar triangles are triangles in which the ratio of the corresponding sides of the triangles are equivalent for the three sides of the triangle.
The location of the tree divides the hypotenuse side and the base of the triangle formed by the building into two parts of the same length, therefore;
The length of the hypotenuse side to the building = 2 × 108 ft = 216 ft
The length of the base to the building = 2 × 90 ft = 180 ft
The ratio of corresponding sides of similar triangles and the trigonometric ratio of sines, indicates that we get;
Height of the tree/108 = 120/216
Height of the tree = 108 × (120/216) = 60 feet

find the volume of the pyramid. round to the nearest hundredth
Answer:
A. 17.35 mm³
Step-by-step explanation:
Volume of a Pyramid
[tex]V = \frac{1}{3}Bh[/tex]
V ... volume
B ... area of base
h ... height
The base of this pyramid is a square. Area of a square is side times side.
[tex]B = 3.5 \times 3.5[/tex]
Let's substitute in the formula.
[tex]V = \frac{1}{3}Bh\\\\V = \frac{1}{3}(3.5\times 3.5)(4.25)\\\\V = \frac{1}{3}(12.25)(4.25)\\\\V \approx 17.35417 \text{ mm}^3[/tex]
Now let's round to the nearest hundredth.
V = 17.35 mm³

Decide whether quadrilateral ABCD with vertices 4(3,1), B(-1,-1) C(1,3), and D(5,5) is a rectangle, rhombus,
square, or parallelogram.
Answer: rectangle
Step-by-step explanation:
From the options, it is implied that it is a parallelogram.
From inspection, we can tell that not all the sides are congruent, so it is not a rhombus or a square.
To determine if it is a rectangle, we can use the slope formula to see if there is a pair of perpendicular sides (if this is the case, then this will be a parallelogram with a right angle, making it a rectangle)
[tex]m_{\overline{AB}}=\frac{1-0}{-4-(-3)}=-1\\m_{\overline{BC}}=\frac{4-1}{-1-(-4)}=1\\\therefore \overline{AB} \perp \overline{BC} \text{ because} \left(m_\overline{AB} \right) \left(m_{\overline{BC} \right)=1[/tex]
So, the most specific classification is a rectangle.

Solve |5x + 30| = 10x Identify the solution and an extraneous solution
Answer:
B
Step-by-step explanation:
the absolute value function always gives a positive result
However, the value inside can be positive or negative, that is
5x + 30 = 10x or - (5x + 30) = 10x
solving both
5x + 30 = 10x (subtract 5x from both sides )
30 = 5x ( divide both sides by 5 )
6 = x
or
- (5x + 30) = 10x
- 5x - 30 = 10x ( add 5x to both sides )
- 30 = 15x ( divide both sides by 15 )
- 2 = x
As a check
substitute these values into the equation and if both sides are equal then it is a solution.
x = 6
left side = | 5(6) + 30 | = | 30 + 30 | = | 60| = 60
right side = 10(6) = 60
Then x = 6 is a solution
x = - 2
left side = | 5(- 2) + 30 | = | - 10 + 30 | = | 20 | = 20
right side = 10(- 2) = - 20 ≠ 20
Thus x = - 2 is an extraneous solution
