The posters wording makes sense I just cant think of the right equation

Thank you! :)

i said you get 1 dollar

the riddle is you get a dollar for every dollar you are given 

think!

Differentiation (aka, derivatives).

Your question is worded kind of poorly..

"If you get a doller for every doller you get"

kind of sounds like you'll only get one doller.. if you're trying to say 

"you're given an extra doller for every doller you get"

then that's an entirely different thing.. 

I think u have two dollars in all.

Some bacteria are known to double their numbers every hour. So that n number of bacteria will quadruple their numbers in 2 hours. Or their numbers will increase 400% in two hours.

W*f is that. Ive done some complex math but that is something else

I solved it. The solution is y=-3x 

(as b=0)

Thanks all for the help.

no, it isnt a trick question, i said you were given a dollar w*f

Trick question you have zero dollars.

I'm not sure that this answer is right (at least in the terms that OP was reffering to). The product rule for derrivatives is 

derivative of fg = fg' + f'g

I *think* the two functions given in the equation would be:

p(t) = 961400+9200t

a(x) = 30593+1400t

p'(t) = 9200

a'(t) = 1400

so the derivative of pa is = pa' + p'a

110/60 =1 5/6 Km the train travels in 1 minute. Therefore,

37 / 1 5/6 =37 X 6/11=20 minutes and about 11 seconds in the Eurotunnel.

think harder, you get a dollar for every dollar given

The answer is 1 dollar. Because you said you were given a dollar

it is y = 2bx+ 2- 6 x 5mx b2

Solve for x:
x^2-5 x+3 = 0

Subtract 3 from both sides:
x^2-5 x = -3

Add 25/4 to both sides:
x^2-5 x+25/4 = 13/4

Write the left hand side as a square:
(x-5/2)^2 = 13/4

Take the square root of both sides:
x-5/2 = sqrt(13)/2 or x-5/2 = -sqrt(13)/2

Add 5/2 to both sides:
x = 5/2+sqrt(13)/2 or x-5/2 = -sqrt(13)/2

Add 5/2 to both sides:
Answer: |  x = 5/2+sqrt(13)/2          or           x = 5/2-sqrt(13)/2

Okay, but what would the equation of the line be in y=mx+b form?

nope your getting there, want me to tell you?

This has me totally puzzled is the answer 2.

answer is 2

Estimate the rate at which the total personal income is rising. The population is 961,400 and it increases by 9,200 people per year. The average annual income is 30,593 dollars per capita, and this increases by 1,400 dollars per year.

Using the product rule, estimate the rate at which the total personal income rises. Please help. I don't even know where to begin.

$30,593 X 961,400 =$29,412,110,200 Total annual income for entire population.

$1,400 X 961,400 =$1,345,960,000 Expected annual income increase for entire population

$29,412,110,200 + $1,345,960,000 =$30,758,070,200 Annual income after expected increase.

961,400 + 9,200 =970,600 Total population after expected increase. Therefore,

$30,758,070,200 / 970,600 =$31,689.75 Expected average annual income after increase.

$31,689.75/$30,593.00=1.0358 - 1 =.0358 X 100 =3.58% Estimate of the rate at which income will rise for the entire population.

No it doesnt have you even read it properly, remember you get a dolllar for every dollar and your given a dollar

A dollar.         The way your question is worded makes the answer :  A dollar.

Moles of O2 = 120/32 =  3.75 moles

you need TWICE as many Moles of H2   3.75 x 2 = 7.5 moles of H2    7.5 x 2.016 = 15.12 gms oh h2

120gms of O2  + 15.12 gms H2 = 135.12 gms H20
