if \( \frac{a^2 + b^2 + c^2 - 1024}{ab - bc - ca} = -2 \text{ and } a + b = 5c \)where c>0 then value of c is,
The pie chart given below shows the production of 6 different factories. The total production of all these 6 factories are 22000. The production of a particular factory is shown as a percent of total production of all these 6 factories.
P1 = The value of average production of A, C, D and F.
P2 = The difference between the production of B and E. What is the value of (P1 + P2)?
If p + q = 6 and pq = 4, then what is the value of p3 + q3?
If cos A = \( \frac{9}{41} \), find cot A.
\( \frac{9}{40} \)
\( \frac{41}{40} \)
\( \frac{40}{9} \)
\( \frac{9}{41} \)
