Chapter 12.3, Problem 37E
Grading Methods A mean average of 60 on seven exams is needed to pass a course. On her first six exams, Sheryl received grades of 52, 72, 80, 65, 57 and 69.
- a. What grade must she receive on her last exam to pass the course?
- b. An average of 70 is needed to get a C in the course. Is it possible for Sheryl to get a C? If so, what grade must she receive on the seventh exam?
- c. If her lowest grade of the exams already taken is to be dropped, what grade must she receive on her last exam to pass the course?
- d. If her lowest grade of the exams already taken is to be dropped, what grade must she receive on her last exam to get a C in the course?

Make up two polynomial functions, f(x) and g(x).
• f(x) should be of degree 3 or higher. g(x) should be of degree 4 or higher.
• Find f(3) in each of the three ways: substitution, remainder theorem
(synthetic division), and long division. You should get the same answer
three times for f(3).
Find g(-2) once using your choice of the three methods.
ere are many real-world situations that exhibit exponential and logarithmic
nctions.
• Describe two real world scenarios, one exponential and one logarithmic. Do
not identify yet whether your scenarios are logarithmic or exponential.

If the problem seems to require calculus, use a graphical or numerical approach to estimate the solution. STEP 1: Consider the figure in part (a). Since this region is simply a triangle, you may use precalculus methods to solve this part of the problem. First determine the height of the triangle and the length of the triangle's base. height 4 units units base 5 STEP 2: Compute the area of the triangle by employing a formula from precalculus, thus finding the area of the shaded region in part (a). 10 square units STEP 3: Consider the figure in part (b). Since this region is defined by a complicated curve, the problem seems to require calculus. Find an approximation of the shaded region by using a graphical approach.

M (ELES),- m2,1. We know also that all the six unknowns mr,c are non-negative with the exception of Your first task is to find the values of all the six unknowns. Think first, which of the mr,c you should find first. Next, consider a vector v = (-6, 0, 0, 8) T. What's the length of v, i.e., |v|? Using M as transformation matrix, map v onto w by w = Mv provide w with its numeric values. What's the length of w, especially when comparing it to the length of v? Finally, consider another vector p = ( 0, 0, 8, 6) T. What's the angle between v (from above) and p? Using M as transformation matrix, map p onto q by q = Mp - provide q with its numeric values. What's the angle between w and q, especially when comparing it to the angle between v and p?arrow_forward
