x6 x by the power of 6 so x first i think.

rnfp!!!!!!! it so confusing.

I don't understand what this is for.

$V=\dfrac{\pi r^2 h}{3}\\ h=9.1m\\ r = \dfrac{30}{2}=15m$

you can plug and chug the numbers

and some math I understand but just what to make sure if I'm right.

to time my self to see if I can get it done in time be for anyone and see if I'm right to my one ?.

I look if it was right and said if it was. I  giving a? then tell if it right 

never mind

I did not know the Sequence was called. 

ok ok

yes it is a Fibonacci Sequence and it have 10 from 0-9 if you cont 0123456789=10. 1+1+2+3+5+8+13+21+34+55 = 143

Fibonacci Sequence !!!!.

Not sure what you mean by "transformation" but Figure 2 looks like a mirror image of Figure 1.

On any one day Bob will expect to roll once 5/6 of the time, twice 5/6² of the time, three times 5/6³ of the time, ...etc.

Expected number for one day = 1*5/6 + 2*5/6² + 3*5/6³ + ...  = 6/5

Expected number for a non-leap year = 365*6/5 = 438

A pyramid and a prism share the same base. The prism has 99 edges. How many edges (faces ??) does the pyramid have?

I do not know what the definition of a critical value is.

BUT

When x=0

f(0)= 0^(1/9) - 0^(-8/9)

$=0^{1/9}-\frac{1}{0^{8/9}}\\ =0- undefined\\ =undefined$

So there is probably an asymptote at x=0

f(x)= x^(1/9) - x^(-8/9)

$f(x)=x^{1/9}-x^{-8/9}\\ f'(x)=\frac{x^{-8/9}}{9}+\frac{8x^{-17/9}}{9}\\ f'(x)=\frac{1}{9x^{8/9}}+\frac{8}{9x^{17/9}}=0\\ $

By inspection I do not think this is ever the case.

So there are no stationary points.

Here is the graph.

Questions like this is why Jack St. Clair Kilby invented the calculator.  The answer = 6.7527772

.

I think x=0 might be one of the critical values but I'm not sure
