is -3x+4y=8 parallel or perpendicular to -4x+3y=-6
Step-by-step explanation:
4y = 3x +8
y= 3/4x +2
3y = 4x -6
y = 4/3x -2
neither, perpendicular is negative reciprocal, and parallel m is the same. 3/4 =\ 4/3 and they are not negative reciprocals.

A swing base is 72 cm above the ground as shown in figure. When it travels through an angle of 60∘ from its mean position, swing base comes at 252 cm above the ground. What is the length of the arc travelled by the swing in meters?
Answer:
The length of the arc travelled by the swing is approximately 3.77 m
Step-by-step explanation:
The given parameters of the swing are;
The swing base height of the swing above the ground = 72 cm
The swing base height above the when the swing travels an angle of 60° = 252 cm
Therefore we have;
r × cos(60°) = r - 180
180 = r - r × cos(60°)
r = 180/(1 - cos(60°)) = 360
r = 360 cm
The length of the arc travelled by the swing in meters, [tex]l_{arc}[/tex] is given as follows;
[tex]l_{arc} = \dfrac{\theta}{360 ^{\circ}} \times \pi \times 2\times r[/tex]
Therefore;
[tex]l_{arc} = \dfrac{60^{\circ}}{360 ^{\circ}} \times \pi \times 2\times360 = \dfrac{1}{6} \times \pi \times 720 = 120 \cdot \pi[/tex]
The length of the arc travelled by the swing, [tex]l_{arc}[/tex] = 120·π cm
∴ The length of the arc travelled by the swing, [tex]l_{arc}[/tex] = 1.2·π m ≈ 3.77 m
can someone please help me?
Answer:
m<2 = 150
Step-by-step explanation:
m<2 = 150 because of alternate exterior angles

There are 40 students in the 5th grade. 22 of them play soccer. What percentage of the students in the class do NOT play soccer? Please show work i need help
Step-by-step explanation:
If there are 40 kids and 22 of them play soccer that leaves you to subtract 22 from 40 which gives you 18. After that, you put the rest of the 18 students over a total of 40 and divide to get the decimal .45 and if you convert that into a percent you are left with 45%.
1. 40-22=18
2.18/40=.45

Answer:
10x^2-x-24
Step-by-step explanation:
Step-by-step explanation:
First, you have to expand the expression.
[tex](2x + 3)(5x - 8) \\ = (2x)(5x) + (2x)( - 8) + (3)(5x) + (3)( - 8) \\ = 10 {x}^{2} + ( - 16x) + 15x + ( - 24) \\ = 10 {x}^{2} - 16x + 15x - 24 \\ = 10 {x}^{2} - x - 24[/tex]

Find the area of each regular polygon. Round your answer to the nearest tenth if necessary
Answer:
Step-by-step explanation:
13). Area of a square = (Side)²
= (BC)²
Since, diagonals of a square bisect each other at 90°,
ΔBOC is a right triangle.
By applying Pythagoras theorem in the given triangle,
BC² = OB² + OC²
BC² = 2(OB)²
BC² = 2(7√2)²
BC = [tex]\sqrt{196}[/tex]
Area of square ABCD = (BC)²
= (√196)²
= 196 units²
14). Measure of interior angles of the regular hexagon = 120°
Area of the regular hexagon = [tex]\frac{3\sqrt{3}}{2}(\text{side})^2[/tex]
From the given picture,
m∠BAC = m∠ABC = m∠ACB = 60°
Therefore, ΔABC is an isosceles triangle.
And all sides of this triangle will be equal in measure.
AB = AC = BC = 9 units
Area of the given regular hexagon = [tex]\frac{3\sqrt{3}}{2}(9)^2[/tex]
= 210.44 square units
≈ 210.4 square units

Find the probability that a randomly selected points within a square falls in the blue shaded area (circle)
Answer:
78.8 %
Step-by-step explanation:
From the question,
Area of the square = L²
A = L²
Where L = Length of the square.
From the diagram,
L = 4 in
Therefore,
A = 4²
A = 16 in².
Also,
Area of the circle (A') = πr²
Where r = radius of the circle.
Given: r = 2 in
Therefore,
A' = 22/7(2²)
A = 12.6 in²
Hence,
The probability that a randomly selected points within a square falls in the blue shaded area (Pr) = A'/A
Pr = 12.6/16
Pr = 0.7875
Pr(%) = 78.75
Pr(%) = 78.8 %
