Maria started the year with $235 in the bank and is saving $15 a week. Sergio started with $685 and is spending $35 a week. When
inessss [21]

Answer:

9 weeks

Step-by-step explanation:

let the time when they will both have the same amount be x

since Maria is saving then her money is bound to increase

therefore amount she will have after x weeks=235+15x

Sergio is spending so his money is reducing

therefore amount he will have after x weeks=

685-35x

so

235+15x=685-35x

685-235=15x+35x

450=50x

x= 450/50

Use the Quotient Rule to find the UNSIMPLIFIED version of the derivative. R(w)=3w+w^4/ 2w^2+1.
PolarNik [594]

From your previous questions, you know

(3<em>w</em> + <em>w</em>⁴)' = 3 + 4<em>w</em>³

(2<em>w</em>² + 1)' = 4<em>w</em>

So by the quotient rule,

<em>R'(w)</em> = [ (2<em>w</em>² + 1)•(3<em>w</em> + <em>w</em>⁴)' - (3<em>w</em> + <em>w</em>⁴)•(2<em>w</em>² + 1)' ] / (2<em>w</em>² + 1)²

That is, the quotient rule gives

<em>R'(w)</em> = [ (denominator)•(derivative of numerator) - (numerator)•(derivative of denominator) ] / (denominator)²

I'm not entirely sure what is meant by "unsimplified". Technically, you could stop here. But since you already know the component derivatives, might as well put them to use:

<em>R'(w)</em> = [ (2<em>w</em>² + 1)•(3 + 4<em>w</em>³) - (3<em>w</em> + <em>w</em>⁴)•(4<em>w</em>) ] / (2<em>w</em>² + 1)²
