We need more information than that - You cou;d be referring to many different things.
Now that would depend. What do you want to do?
A(t)=Ie^rt
What are your values for t, l, and r ?
I assume l is 75 what about t and r
Chris, they could all be 16.5000000000000000000000000000000000000000000001 cm each
They are only 17 to the nearest cm
3a=6c so a=2c
5b=6c so b=6c/5
$$\\\frac{a+b}{b-c}=(a+b)\div(b-c)\\\\ =\left(2c+\frac{6c}{5}\right)\div\left(\frac{6c}{5}-c}\right)\\\\ =\left(\frac{10c+6c}{5}\right)\div\left(\frac{6c-5c}{5}}\right)\\\\ =\frac{16c}{5}\div\frac{c}{5}}\\\\ =\frac{16c}{5}\times\frac{5}{c}}\\\\\ =16$$
Well I guess they could all be 16.5cm
16.5*20=330cm
Sorry anon but you have found the mean (average) NOT the median (middle)
-7,-1,0,8,4,2,-7, 2
line them up in oder
-7,-7,-1,0,2,2,4,8
The median is the middle score. Here there are 2 middle scores so the median will be the averagae of them.
median=(0+2)/2=2/2=1
The median is 1
(4^2)^8=4^16
Inverse sine is the same as arc sin
So just enter asin(0.2308) on the calculator (on the home page)
An = 2(-3^n)+5^n
$$\\A_n = 2(-3^n)+5^n\\\\ A_0 = 2(-3^0)+5^0=2*1+1=3\\\\ A_1 = 2(-3^1)+5^1=2*-3+5=-1\\\\ A_2 = 2(-3^2)+5^2=2*-6+25=13\\\\ etc$$
