1) two forces f1, and f2 are given by the vectors f, = (pi+5)) n and f, - (31+q)) n. the
r = fi + f2 acts in a direction which is parallel to the vector 21 - 5j.
a find the angle, to 2 decimal places, between r and the vector 21. (2 marks)
b show that 5p + 2q = -25. (4 marks)
c given that p -3, find, to 2 decimal places, the magnitude of r. (4 marks)

21

step-by-step explanation:

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

no oblique asymptote

step-by-step explanation:

to find the oblique asymptote of f(x)

here numerator has degree 1 and denomintor degree 2

degree of numerator < degree of denominator

hence there is no oblique asymptote

when the degree of the denominator > that of the numerator, we saw that the value in the denominator got so much bigger, so quickly,   giving us a horizontal asymptote of the x-axis. or we can write

f(x) = a polynomial of x + a proper fraction.

in this case only we have oblique asymptotes but not when numerator has less degree.
