Answer:
5,035,041
Step-by-step explanation:
Exponential growth:

y = future amount
a = initial amount
r = growth rate
x = number of periods
Part A: growth at the rate of doubling each 15 minutes for 274 minutes
Each period is 15 minutes.
a = 37
x = 274/15 = number of periods
r = 100%

-------------------------------------------------------------------------------------
Exponential decay:

The growth takes place from 9 AM for 274 minutes, or 4 hours and 34 minutes, until 1:34 PM. The decay goes from 1:34 PM to 7 PM, or 5 hours and 26 minutes, or 326 minutes
Part B: decay at the rate of 6% each 24 minutes for 326 minutes


Answer: 5,035,041
45*6 = 270
280-270 = 10
45 can go into 280 , only 6 times, and their is a remainder of 10.
Answer: 48.
Step 1: multiple 90 puzzles x 0.4 to find how many she has already completed = 36.
Step 2: subtract the number completed (36) from the total (90). 90-36 = 54
Step 3: subtract the 6 more she will complete. 54-6 = 48
Answer: the slope of this line is 2/3
Step-by-step explanation:
If you use rise/run, you will find that rise=2 and run=3, so the slope 2/3.
