The maximum number of intersection points of a parabola and ellipse is 4.
Calculate Δ = b^2 -4ac => Δ = 169 => k1 = 3/2; k2 = -5 => 2k^2 + 7k - 15 = 2*(k -3/2)(k+5) = (2k - 3)(k+5);
Given from the question
first fraction = 5/6
second fraction = 1/3
We're asked what's the difference between the fraction
First, we need to equalize the denominator to the same number. The first denominator is 6, the second denominator is 3. I'd like to make them both 6. So the second denominator needs to be multiplied by 2, so does the numerator
second fraction = 1/3
second fraction = (1 × 2)/(3 × 2)
second fraction = 2/6
Second, we have new fractions which have the same denominator. Calculate the difference
d = first fraction - second fraction
d = 5/6 - 2/6
d = 3/6
The red tape is 3/6 yard more than the green tape.
From what I can pick up from your problem statement, you want to know "<span>a similar charm has a diameter of 4 cm what is the circumference." Please, would you use proper punctuation in your writing, for greater clarity:
"A</span><span> similar charm has a diameter of 4 cm. What is the circumference?"
The formula for the circumference of a circle, when the diameter is known, is
C=</span>

d or C=pi*d
In this case, with diamter 4 cm, the circumference, C, is 4pi cm.
I dare this to be a most liked comment!
