Consider the function, ? (?) = 20?² + 28? - 17
Determine both real roots of the quadratic equation as follows:
i. Graphically and determine the intervals for both roots to be used in iii & iv.
ii. Using the quadratic formula
iii. Using the bisection method until ?? is less than ?? = 0.5%
iv. Using the false-position method until ?? is less than ?? = 0.5%

Consider the the differential equation
2xy''+ 5y'+xy= 0
1) determine the indicial equation and its roots
2) For each root of the indicial equation, determine the
recurrence relation
3) Do the indicial roots differ by an integer? If yes, find the
general solution on (0,∞). If not, find the series solution
corresponding to the larger root on (0,∞)

A store sold 12 stereos on Monday, 17 on Tuesday, 28 on
Wednesday, 17 on Thursday and 26 on Friday. AT the .01 level, test
if there is a difference in the number of stereos sold on each
weekday. State the hypotheses and identify the claim, find the
critical value(s), compute the test value, make the decision and
summarize the results. Show all work and formulas - sample question
that I don't get.
