Monthly Payment for a Home: If you borrow $120,000 at an APR of 6% in order to buy a home, and if the lending institution compounds interest continuously, then your monthly payment
a. Make a graph of M versus Y. in choosing a graphing window, you should note that a home mortgage rarely extends beyond 30 years.
b. Express in functional notation your monthly payment if you pay off the loan in 20 years, and then use the graph to find that value.
c. Use the graph to find your monthly payment if you pay off the loan in 30 years.
d. From part b to part c of this exercise, you increased the debt period by 50%. Did this decrease your monthly payment by 50%?
e. Is the graph concave up or concave down?
Explain your answer in practical terms.
f. Calculate the average decreases per year in your monthly payment from a loan period of 25 to a loan period of 30 years.

Solving A C = B for C provides youwith the coefficients of a natural cubic spline curve that interpolates these points.Additionally, you have been given A and B, but some elements are missing. Moreover, the last two rowsof A are entirely absent. Your task is to determine and fill in the missing elements. For the last two rows,enforce a zero tangent at the beginning (in p1) and a not-a-knot boundary condition in p2. The matricesA and B are given as follows:Explain how to find the entries of A and B . How would you adapt these matrices if the data pointswere 3D? What if your spline should go through five data points? How many “extra rows” would there thenbe (with “extra” meaning “in addition to securing C2-continuity”)?arrow_forwardWhich graph represents f(x) = √x-2+3?arrow_forwardPractice Assignment 5.6 Rational Functions M Practice Assig Practice Assignment 5.6 Rational Functions Score: 120/150 Answered: 12/15 Question 10 A Write an equation for the function graphed below 5 + 4 1 2 H + + -7 -6 -5 -4 -3 -2 -1 2 34567 | -2 ర y = Question Help: Video Message instructor Post to forum Submit Questionarrow_forwardit's not algebra 4th gradearrow_forwardCan you tell me if I answered and showed my work correctlyarrow_forwardarrow_back_iosSEE MORE QUESTIONSarrow_forward_ios
