First: work out the difference (increase) between the two numbers you are comparing. Increase = New number - Original Number
Then: divide the increase by the original number and multiply the answer by 100. % Increase = Increase ÷ Original Numberｘ100<span>
30 - 22 = 8
8</span> ÷ 22ｘ100 = 36.3636363636
The cross section of the satellite dish is an illustration of a quadratic function
The quadratic function that models the cross-section is y = 1/6(x^2 - 9)
<h3>How to determie the equation of the cross-section?</h3>
The given parameters are:
Width = 6 feet
Depth = 1.5 feet
Express the width the sum of two equal numbers
Width = 3 + 3
The above means that, the equation of the cross section passes through the x-axis at:
x = -3 and 3
So, we have:
y = a(x - 3) * (x + 3)
Express as the difference of two squares
y = a(x^2 - 9)
The depth is 1.5.
This is represented as: (x,y) =(0,-1.5)
So, we have:
-1.5 = a(0^2 - 9)
Evaluate the exponent
-1.5 = -9a
Divide both sides by -9
a = 1/6
Substitute 1/6 for a in y = a(x^2 - 9)
y = 1/6(x^2 - 9)
Hence, the quadratic function that models the cross-section is y = 1/6(x^2 - 9)

Answer:
It represents a non-proportional relationship
Step-by-step explanation:
because in order for it to be proportional it has to pass (0,0) but this equation's y-intercept is (0,3).
Answer:
Perpendicular to base
Step-by-step explanation:
The cut creates two rectangular prisms (each angle must be 90 degrees)
The cut is perpendicular to the base
1 yard = 0.9144 meters
1 yard * 10 = 0.9144 meters * 10
10 yards = 9.144 meters
9.144 meters
