Let Q represent a mass of carbon 14 (14C) (in grams), whose half-life is 5715 years. The quantity of carbon 14 present after t years is given by the following. Q = 13

1
2
t/5715

(a) Determine the initial quantity (when t = 0).
g

(b) Determine the quantity present after 2000 years. (Round your answer to two decimal places.)
g

(c) Sketch the graph of the function over the interval t = 0 to t = 10,000.

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

6 on both sides and twelve on the top and the bottom

step-by-step explanation:

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1
