Complete factorization of 3X squared -10 X +8

 (3x-4)(x-2)

Step-by-step explanation: 3x² -10x + 8

.   ax² + bx +c  format   multiply a×c . 3×8=24 . refactor 24 as 2×12

 transitional factors: (3x - 2)(3x -12) . reduce (3x-12) ÷3 becomes (3x-4) (x-2)

use new factors to check (3x - 4)(x - 2) .FOIL (3x)(x)=3x² -6x-4x=-10  (-2)(-4)=+8

True: 3x² -10x + 8

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
