<PRE><B>Question 330627</B>
Convert to decimal notation. 8.83 * 10^7. I came up with this: 0.00000883 since the answer is 88300000. Is this correct?
10^7 = 10,000,000
8.83*10000000 = 88300000
{{{0.00000883 = 8.83*10^-6}}}
--------------------------
Question 2. How do I evaluate the polynomial for x= -2? The equation is 2x^2-5x+1. When x= -2, 2x^2-5x+1 equals ? 
2x^2-5x+1
sub -2 for x
= 2*(-2)^2 -5(-2) + 1
= 8 + 10 + 1
= 19
