What was the area covered by the oil slick when Lindsay first saw it (at t = 0)? In the remaining questions, express the rate of growth of the oil slick in square meters per hour.

a. At what average rate did the oil slick grow during the first 2 hours after Lindsay’s initial observation?

b. At what average rate did the oil slick grow during the first half-hour after Lindsay’s initial observation?

c. At what average rate did the oil slick grow during the 15 minutes before Lindsay’s initial observation?

At what rate was the oil slick growing at the instant when Lindsay first saw it?

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
