The pollutant PCB (polychlorinated biphenyl) can affect the thickness of pelican eggshells. Thinking of the thickness, T, of the
gayaneshka [121]

Answer:

The expression f(200) depicts the value of the concentration of the pollutant, which when substituted in the expression T = f(P) will give the value of the thickness of the pelican eggs.

Step-by-step explanation:

Since we are given that T = f(P)

Where T = thickness of the eggs

P = concentration in ppm ((parts per million))

Considering f(200) comparing to f(P)

The expression f(200) depicts the value of the concentration of the pollutant, which when substiuted in the expression T = f(P) will give the value of the thickness of the pelican eggs.

i.e substituted the value of the concentration in ppm to get the thickness of the pelican eggs in mm. since the expression shows thickness of pelican eggs as a function of the concentration. for every 200ppm of concentration, the numerical value of the thickness of pelican eggs can be gotten.

Mary Stahley invested $2500 in a 36-month certifi- cate of deposit (CD) that earned 8.5% annual simple interest. When the CD mat
nata0808 [166]

9514 1404 393

Answer:

  $13,916.24

Step-by-step explanation:

First, we need to find the value of the CD at maturity.

  A = P(1 +rt) . . . . simple interest rate r for t years

  A = $2500(1 +0.085·3) = $2500×1.255 = $3137.50

__

Now, we can find the value of the account with compound interest.

  A = P(1 +r)^t . . . . . rate r compounded annually for t years

  A = $3137.50 × 1.18^9 = $13,916.24

The mutual fund was worth $13,916.24 after 9 years.
