2 sin 70.cos 20 = sin 90+ sin 50
plz

Jehhnd. rhehbf ehnd new e hw ended nehru shh snow rheh 6 cents!

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0 

Ithink it may be 10^3,that mean 10 'exponent ^3 would the population scientific in terms to evaluate by such and
