Answer:
Study 1 Answers:
1) 0.76 represents the multiplier of the bacteria, in this case it is decreasing by 24% because the formula for exponential decay is 1 - r.
2) 1290 represents the initial value, or before the study began.
Study 2 Answers:
1) 1180 is the initial value, or before the study began.
2) Study 1 started with more bacteria
3) Study 1 is experiencing exponential decay, while study 2 is experiencing exponential growth
Step-by-step explanation:
Exponential functions are in the form 
, where a is the initial value, b is the multiplier, and x represents inputs, such as hours after a bacteria study.
Any multiplier above 1.00 is experiencing exponential growth, meaning it grows gradually over time, and any multiplier below 1.00 is experiencing exponential decay, meaning it decreases in population over time.
Answer:
200.96 ft²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius ) , then
A = 3.14 × 8² = 3.14 × 64 = 200.96 ft²
Answer:
Option C
Step-by-step explanation:
As per the contract:
"Any rental not received by midnight on the day it is due is subject to a late charge of $1.50 for each day it is late."
this makes option a: "Pay a $1.50 late fee per movie per day past the due date" responsibility of customer
"All rentals are due back by midnight of the due date as printed on the transaction receipt."
this makes option b: "Get his or her rentals back by midnight the day they are due." responsibility of customer
"Any rental not returned by the fifth day after the due date will be transferred to a sale. The Customer will then be required to pay the purchase price of the item in addition to five (5) days of late fees. "
this makes option d: "Pay the purchase price and five days of late fees for any item kept more than five days past the due date." responsibility of customer
Hence option C is correct: Return a rental item kept out thirteen days past the due date!
