    Area Triangle
AI Thread Summary
The area of a triangle with a base of 2 and 3/4 and a height of 4/9 is calculated using the formula 1/2 * (b*h). The correct calculation yields an area of 11/18. Confirmation of the solution indicates that the approach taken is valid. It is important to ensure that the height is perpendicular to the base for accurate results. The discussion emphasizes the need for clarity in defining the height in relation to the base.

What you've done is correct given how you've described the problem. Are you just unsure about your answer? Because it's right.
 
Yeah, I just want to make sure I was solving these problems correctly, and I had to have a confirm :) ,thankyou!

Just make sure the height is perpendicular (right angled) to the base. If you're taking the height as being slanted to the base, such as having an equilateral triangle with the length of a side given, you can't just say the height is the same length as the base.
 

Thread 'Finding the number of ways to arrange identical balls in a circle (3 different colors)'

I tried to combine those 2 formulas but it didn't work. I tried using another case where there are 2 red balls and 2 blue balls only so when combining the formula I got ##\frac{(4-1)!}{2!2!}=\frac{3}{2}## which does not make sense. Is there any formula to calculate cyclic permutation of identical objects or I have to do it by listing all the possibilities? Thanks

Thread 'Greatest possible value of a constant in polynomial'

Since ##px^9+q## is the factor, then ##x^9=\frac{-q}{p}## will be one of the roots. Let ##f(x)=27x^{18}+bx^9+70##, then: $$27\left(\frac{-q}{p}\right)^2+b\left(\frac{-q}{p}\right)+70=0$$ $$b=27 \frac{q}{p}+70 \frac{p}{q}$$ $$b=\frac{27q^2+70p^2}{pq}$$ From this expression, it looks like there is no greatest value of ##b## because increasing the value of ##p## and ##q## will also increase the value of ##b##. How to find the greatest value of ##b##? Thanks
