Answer:
M(6,5) and G(2,9)
Step-by-step explanation:
B(3,6)
C(9,4)
m = [(3+9)/2 , (6+4)/2]
= (6,5)
M(5,9)
H(8,9)
G(x,y)
[(x+8)/2 , (y+9)/2]=(5,9)
(x+8)/2 = 5
x+8 = 10
x = 2
(y+9)/2 = 9
y+9 = 18
y = 9
G(2,9)

The graph of y2+3x=0 is symmetric with respect to which axis?
2 answers:
<h2>Answer:</h2>
<u>The correct answer is option </u><u>A) The x axis</u>
<h2>Step-by-step explanation:</h2>If a function is symmetric with respect to the x-axis, then f (x) = - f (x). The following graph is symmetric with respect to the y-axis (x = 0). Note that if (x, y) is a point on the graph, then (- x, y) is also a point on the graph. As we can see from the attached graph it shows the same phenomenon
Answer:
The graph of y2+3x=0 is symmetric with respect to the x-axis
Step-by-step explanation:
To establish symmetry with respect to the x-axis we simply substitute -y in place of y in the original equation. If the resulting equation is identical to the original one then the function is said to be symmetric with respect to the x-axis.
In this case we have;
Which is identical to the original equation

Time = 
The distance the bag will travel is 5 meters, and the speed it is traveling at is 1 m/s. Plug these into the formula for time.
= 5 s
5/1 = 5 and the m (meters) cancel out, so you are left with s, seconds.
It will take the bag 5 seconds to travel across the floor.

The depth of the swimming pool that is filled to the top is; 4 m
<h3>Snell's Law</h3>
I have attached a schematic diagram showing this question.
The correct width of the pool is 4 meters. Thus; w = 4 m
Incident Angle; θ₁ = 20°
A right angle is 90° and so the angle θ₂ is calculated from;
θ₂ = 90° - θ₁
θ₂ = 90° - 20°
θ₂ = 70°
We can use snell's law formula to find θ₃.
Thus;
n₁sinθ₂ = n₂sinθ₃
where;
n₁ is refractive index of air = 1
n₂ is refractive index of water = 1.33
Thus;
1*sin 70 = 1.33*sin θ₃
sin θ₃ = (sin 70)/1.33
Solving this gives;
θ₃ = 44.95°
By usage of trigonometric ratios we can find the depth of the pool using;
w/d = tan θ₃
Thus;
d = w/(tan θ₃)
d = 4/(tan 44.95)
d ≈ 4 m
