(a) coordinates of P.
(b) equation of the straight line that passes through N(3, -5) and P.
2. (a) Find the sum of the series 32 + 8 + 2 + …,
(b) Simplify: 1−25−3−1+25+3
3. Without using mathematical tables or calculator, find, in surd form (radicals), the value of tan22.5∘.
3. The ages, (in years), of a group of 18 adults have the following statistics, ∑x²=745 and ∑x²=33951.
