In each of Problems 1 through 14: (a) Seek power series solutions of the given differential equation about the given point x0; find the recurrence relation. (b) Find the first four terms in each of two solutions y1 and y2 (unless the series terminates sooner). (c) By evaluating the Wronskian W(y1, y2)(x0), show that y1 and y2 form a fundamental set of solutions. (d) If possible, find the general term in each solution.

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

7/2

(decimal: 3.5)

welcome ; )

step-by-step explanation:

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
