Confidential a pilot flies his aircraft, whose speed in still air is 350 kmh) from a point x to a point y, a distance of 430 km and y is located due north-east of xi a wind of 50 kmhy is blowing from the west. find the bearing on which the plane must be steered 13) [3] (ii) the time taken to fly from x to y.

Give all possible names for the line shown.calculation tip: lines can be written with either point first.

Use addition and subtraction to simplify the following polynomials. a. add polynomials: (3 – 4x + 8x^2) + (–6 + 2x – 5x^2) step 1: rewrite the polynomials without the parentheses. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial. b. subtract polynomials: (3x – 5 – 7x^2) – (–2 + 6x^2 – 5x) step 1: rewrite the polynomials without the parentheses. remember to multiply each term in the second parentheses by –1. show your work. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial.
