Answer:

Add I, add 9, repeat.

Step-by-step explanation:

It is because if you look at the Add 9 subtract 8, repeat. it won't work

If you look at add 10, subtract 9, repeat. it its just like the first one, it won't work.

If you look at add 1, add 10, repeat, it also won't work from when you are getting 6 to 15.

So if you look at Add I, add 9, repeat., it works for all.

Jed wants to earn 25% annual net income on his $50,000 cash investment in property his annual expense of owning the property are

Elena L [17]

Answer: $1,842

Step-by-step explanation:

John wants to earn 25% of his investment of $50,000 which is:

= 25% * 50,000

= $12,500

He has expenses of $9,600 yearly so the rent he should charge per year in order to make his 25% requirement as income is:

= Expenses + Return

= 9,600 + 12,500

= $22,100

Rent per month is:

= 22,100 / 12

= $1,842

The coefficient of x^ky^n-k in the expansion of (x+y)^n equals (nk). True or false.

AVprozaik [17]

Answer:

The correct option is;

False

Step-by-step explanation:

The coefficient of x^k·y^(n-k) is nk, False

The kth coefficient of the binomial expansion, (x + y)ⁿ is $\dbinom{n}{k} = \dfrac{n!}{k!\cdot (n-k)!} = C(n,k)$

Where;

k = r - 1

r = The term in the series

For an example the expansion of (x + y)⁵, we have;

(x + y)⁵ = x⁵ + 5·x⁴·y + 10·x³·y² + 10·x²·y³ + 5·x·y⁴ + y⁵

The third term, (k = 3) coefficient is 10 while n×k = 3×5 = 15

Therefore, the coefficient of x^k·y^(n-k) for the expansion (x + y)ⁿ = $C(n,k)$ not nk
