Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. f ( x ) = 9 x 3 + 2 x 2
− 5 x + 4 fx=9x3+2x2-5x+4 and g ( x ) = 5 x 3 − 7 x + 4 . g(x)=5x3-7x+4. what is f ( x ) − g ( x ) ? f(x)-g(x)? Show all of your steps and write your final answer in factored form.
Ok so cos(x) = sin(90-x) so using that you can get sin(7x-15) = sin(90-(3x+5)) so 7x-15 = -3x+85. 10x = 100 and x = 10. Use that to find the 2 angles are 55 and 35
