Define the double factorial of n, denoted , as follows: ={1⋅3⋅5(n−2)⋅nif n is odd 2⋅4⋅6(n−2)⋅nif n is even and (−1)==1. find the radius of convergence for the given power series. ∑n=1[infinity]3n⋅n! ⋅(5n+8)! ⋅(2n)⋅[(n+9)! ]5⋅(4n−4)(−6x+4)n the radius of convergence, r

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
