In an arithmetic sequence, a3 = 7 and a8 = 32. Determine a formula for an the nth term of this sequence.

Evaluate 4 a for a = 5 2/3 . express your answer in simplest form.

Which of these angles are supplementary? a. 100o and 90o b. 78o and 102o c. 54o and 146o d. 12o and 78o

To find the inverse of a number a, one can use the equation f(c) = a-1/c=0 where c is the inverse of a use the secant method of finding roots of equations to find the inverse of a = 2.5 ,er = 0.001%
