P=Poe (rt)? I know that P is the population (I am assuming that (rt) could be annual growth rate)....can someone please fill in the rest for me? Or if I have written it down incorrectly, please correct it =)

We know that 6.6 x 10 (to the ninth power) is our current population...
We know that .455% is a conservative rate of annual growth...

Please help me with the rest...Thanks

Find the Laplace transform of f(t)=[e^(-2t)]cosh(3t)

Find the Laplace inverse transform of F(s)=(s+2)^2/(s+3)^5

And last one is Use the Laplace transform to solve the equation
y^(2)-2y^(1)+y=f(t), y(0)=y^(1)=0 where f(t) ={t^2, 0<(or equal)t<1 and 2t-1, t>(or equal) 1


I think I am just missing a step in each of these that is causing me to get a very strange answer for them. Help on any of these would be appreciated.

1) Find the Limit as x ->infinity of (1 + (10/x))^4x

I've gotten tot he point where it is a 1 ^ Infinity form and have used the Natural Log properties to get it to Ln y = 4x Ln(1 + (10/x))

I do not know where to go from there

2) Find the Limit as x--> Infinity of (x e^(1/x) - x)

I believe this is an Infinity - Infinity problem but don't know how to get it into a 0/0 or Infinity/Infinity form.

3) Find the Limit as x ---> positive Infinity of Sqrt(2+ (x^2)) / x

(Just incase, Sqrt = Square Root)


Any help or suggestions would be great

Thanks

I know you multiply cm by 0.01 to convert to meters but if I was finding the area of something with sides 11 cm and 11 cm and I had to have the area in meters, would I convert the cm to meter first and then multiply or would I multiply and then convert. I'm confused because it gives 2 different answers.

11 cm x 11 cm = 121 cm^2
121 cm^2 x 0.01 = 1.21 m^2

or

11 cm x .01 = .11 m
.11 m x .11 m = 0.0121 m^2

Thank you!

2007-11-08 14:43:48 · 9 answers · asked by Hilary_m 1

I'm doing homework/studying for a test right now and I think the reason I am not getting right answers is the limits I choose for triple (and some double) integration problems.

For example...one problem is: evaluate the triple integral - f(x,y,z)= x+y; T is the region between the surfaces z=2-x^2 and z=x^2 for 0<=y<=3 . The limits I put on it were: y: 3 to 0; x: sqrt(2) to 0 (my reasoning for this is from using the z=2-x^2 equation and evaluating it for z=0...is this valid?); and z: 2-x^2 to x^2 ...If these are right, then I'm making computational errors, but I get it. If these are not right, then I do not get it.

Any light you could shed on either the problem or determining the limits would be very much appreciated. By the way, the right answer to that problem is 12. Thanks.

is C*xC* isomorphic to C* if yes prove it

ok so i started with
say just using & as a variable say phi or alpha
so &: C*xC*----->C8
then &: (a+bi,c+di)------->((a+c)+(b+d)i)
and i know i have to prove that it is one-one and onto and preserves operation

to prove one-one have to prove
that if &( a+bi,c+di)= &(e+fi,g+hi)
then (a+bi,c+di)=(e+fi,g+hi)

am i on the right track or totally wrong?

I have a chapter test tomorrow and I cannot understand how to find the maxinum profit using linear programming. Here's a similar question to the one on the test. It's not homework. Please help. Thanks.

A lunch stand makes $.75 profit on each chef's salad and a $1.20 on each Caesar salad. On a typical weekday, it sells betwween 40 to 60 chef's salads and between 35 and 50 Caeser salads. The total number has never exceeded 100 salads. How many of each type should be prepared in order to maximize profit?
