NAME: Jen Harper____________________________ Student Answer form Unit 5; show all work for full credit; trial and error (guess and check) methods are not appropriate; use methods covered in class. 1. A . answer 147.56 when working with this equation and messing with both sides the new formula looks like 0.05t=ln*1600 which then could be t=1600/0.05=147.56 B answer is 5.02 ln(4x)=3 4x=e^3 (e^3)/4=5.02 C answer -4 Log2(8-6x)=5 8-6x=2^5=32 6x=8-32=-24 -24/6=-4 D I could not find a solution for this equation.. 2. A on the graph it looks like it moved to the left about 5 units

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
