Implicit differentiation
chain rule is important here

I'll show the steps partially
e^y+xe^yy'-4y'=2
xe^yy'-4y'=2-e^y
y'(xe^y-4)=2-e^y
y'=\dfrac{2-e^y}{xe^y-4}
now evaluate for (-2,2)
x=-2 and y=2
y'=\dfrac{2-e^2}{-2e^2-4}
y'=\dfrac{2-e^2}{-2e^2-4}
y'=\dfrac{e^2-2}{2e^2+4}
that's it, simplest form

Alchen [17]
Rate x time = distance
25   x  35/60 = distance  (35/60 is 35 minutes out of an hour- 60 minutes)
25/1 x 7/12  = distance (I put the 25 over 1 and reduced 35/60)
175/12 ≈ 14.58 miles

Notice that the time had to be in a fraction of an hour in order to do this.

Present value sura wiggle would like to make a single investment have 2.2 million at the time of her retirement in 28 years she
levacccp [35]

Answer:

if the annual interest rate is 7%, then you need to invest:

present value = future value / (1 + i)ⁿ

  • future value = $2,200,000
  • i = 7%
  • n = 28 years

present value = $2,200,000 / (1 + 7%)²⁸ = $330,884.87

if the interest rate is 15%, the you need to deposit a smaller amount:

present value = future value / (1 + i)ⁿ

  • future value = $2,200,000
  • i = 15%
  • n = 28 years

present value = $2,200,000 / (1 + 15%)²⁸ = $43,942.34
