Answer:

The puppy weighed 6 pounds at birth

Step-by-step explanation:

You go from 4 to 0...seeing as the weight is changing by 2.5..you subtract 2.5 by 16, 4 times in order to get the birth weight.

16 - 2.5= 13.5 - 2.5 = 11 - 2.5= 8.5 - 2.5 =6

A rumor spreads among a group of 400 people. The number of people, N(t), who have heard the rumor by the time t in hours since t

Sindrei [870]

Answer:

about 15 hours

Step-by-step explanation:

You want to find t such that N(t)=200. Fill in the equation with that information and solve for t.

200 = 400/(1 +399e^(-0.4t))

1 +399e^(-0.4t) = 400/200 = 2 . . . . . multiply by (1+399e^(-0.4t))/200

399e^(-0.4t) = 1 . . . . . . . . . . . . . . . . . . subtract 1

e^(-0.4t) = 1/399 . . . . . . . . . . . . . . . . . .divide by 399

-0.4t = ln(1/399) . . . . . . . take the natural log

t = ln(399)/0.4 ≈ 14.972 . . . . . . . divide by -0.4, simplify

Rounded to tenths, it will take 15.0 hours for half the people to have heard the rumor.
