Angles α and β are the two acute angles in a right triangle. use the relationship between sine and cosine to find the value of β if β < α. sin( x 2 + 2x) = cos(2x + 3x 2 ) a) 15° b) 37.5° c) 52.5° d) 75°

If i had 1234 apples and 1 banana what is the total amount

Asinusoidal function whose frequency is 1/6pi

The random variable x has probability density function f (x) = k(−x²+5x−4) 1 ≤ x ≤ 4 or =0 1 show that k = 2/9 find 2 e(x), 3 the mode of x, 4 the cumulative distribution function f(x) for all x. 5 evaluate p(x ≤ 2.5). 6 deduce the value of the median and comment on the shape of the distribution.
