A(n)=ar^(n-1)  so

100=4r^9

25=r^9

ln25=9lnr

ln25/9=lnr

r=e^(ln25/9)

a(n)=4e^((n-1)(ln25/9)  if you wanted an approximation...

a(n)=4(1.43^(n-1))

3) What is an equation for the line that passes through the coordinates (-1.2) and (7,6) ?
OLEGan [10]

Answer:

y=\frac{1}{2} x+\frac{5}{2}

Step-by-step explanation:

First find the slope using the slope using the given points. Remember that the slope is the change in y over the change in x.  

\frac{6-2}{7- (-1)}=\frac{4}{8}=\frac{1}{2}

So now we have the equation y=\frac{1}{2} x+b, and we need to find out what b is. We can do this by pointing a point (either one, but I'll use -1,2) into the equation

2=\frac{1}{2}(-1)+b

Rearrange the equation so it equals b

\frac{5}{2}=b

Put it together and that's the final equation!

y=\frac{1}{2} x+\frac{5}{2}
