First note that $\frac{2^n+1}{2^{n+1}} = \frac{2^n}{2^{n+1}} + \frac{1}{2^{n+1}} = \frac{1}{2} + \frac{1}{2^{n+1}}$

If you take limit, then you have $\lim_{n \to \infty}( \frac{1}{2} + \frac{1}{2^{n+1}})= \lim_{n \to \infty}( \frac{1}{2}) +\lim_{n \to \infty}(\frac{1}{2^{n+1}})=\frac{1}{2} +0= \frac{1}{2}$

there is a line that includes the point (6,-4) and has the slope of -2. What is the equation in slope intercept form

Helga [31]

Answer:

y= -2x+8

Step-by-step explanation:

y-y₁=m(x-x₁)

This is the point slope form equation that can be used to solve this.

Plug in the slope for m and (6,-4) for (x₁,y₁)

y-(-4)=-2(x-6)

Simplify.

y+4= -2x+12

y= -2x+8

25 minutes

Step-by-step explanation:

When there are to people washing one elephant they will take half the time.

Mary takes longer then Nigel so once Nigel is finished Mary will still wash her side for 5 minutes extra.
