Write 12 and 23 as fractions with denominators of 6. Thenadd the renamed fractions. Write the answer as a mixed number.

L5 - 6 There is a base that occurs frequently in applications and is especially useful in calculus. It is the irrational number e. NOTE: e ≈ The importance of e: Consider the slope of the tangent line to the graph of x f(x)= b at the point (0,1). If b =2 f b =3 If b =2 , m tan ≈ 0.69 and if b =3 , m tan ≈ 1.1. We will see the slope of the tangent lin ye= toe at x =0 is exactly 1.
