We find<span> the first derivative of the curve, and evaluate it at </span>x<span>=1 (which we will use to obtain the </span>slope<span> of the </span>line tangent<span> to the curve at (1,−1)). So we have a </span>point<span> on the </span>tangent line: (x0,y0<span>)=(1,−1) and the </span>slope<span> of the </span>line tangent<span> at that </span>point<span>: m=−13.</span>
The answer is D. The polynomial is irreducible because 12 can’t be squared.
A=42
C=90
B=48
We can reason that C will be equal to 90 since it is the right angle. So to find B we have to subtract 90 from 180 to get 90 then subtract 42 to get 48
B=48 degrees
