Equation of ellipse is of form where are the x-intercepts and are the y-intercepts . If then it is a horizontal ellipse and if then it is a vertical ellipse .
For horizontal axis ,
Here, are known as the vertices of ellipse and are the co-vertices of ellipse .
Horizontal axis is known as the major axis and vertical axis is known as the minor axis .
Here, x-intercepts are , take a = 5
y-intercepts are , take b = 3
As , it is a horizontal ellipse .
On putting a = 5 and b = 3 , we get equation as
, where l - is a side
(Original Price)(Tax Percent) = Amount
Remember to turn the percent into decimal form first!
(26.50)(0.05) = 1.325
Do not round the results until you are done solving the problem!
(Original Price) + (Amount Tax) = $$$
(26.50) + (1.325) = 27.825
Round the results now!
the minimum width can be 5 because 9 times 5 is 45 the area using the formula length times width but the question is asking greater than 45 and 9 times any number greater than 5 is greater than 45
slope formula: (y2-y1)/(x2-x1)
w =12 cm
l = 24 cm
P = 2w + 2l
We know the perimeter is 72 and the length is twice the width (l = 2w)
Substituting P = 72 and l = 2w
72 = 2w + 2(2w)
72 = 2w+ 4w
Combine like terms
72 = 6w
Divide each side by 6
12 = w
Now we need to find l
l = 2w
l = 24
We can just try and find what works! since we can subtract 12 from -2 and get -14, we might try subtracting 12 every time. After we test it out, we see that is is correct!
Either or , depending on whether is larger than .
The two roots (might necessarily be distinct or real) of the quadratic equation
, where , , and are constants and are
The difference between the two will be either:
