1. What is the growth/ decay rate for this exponential function?
Firdavs [7]

Answer:

1. The growth rate is 2

2. The sample is losing half its mass, so the decay factor is 1/2 or 0.5

Step-by-step explanation:

The growth and decay factor in an exponential function is the number that is being multiplied to the power of x

  • It is a growth rate when that number is greater than 1
  • It is a decay rate when the number is less than 1
  • If it's 1 then it's not growing or decaying
  • If it's 0 you will have an answer of 0

Answer:

5 folders and 5 pens = yes

6 pens and 6 erasers = yes

1 pen and 4 notebooks = no

3 folders and 7 erasers = no

4 folders and 2 notebooks = yes

Step-by-step explanation:

Max total = $10

(5 folders x 1.29) + (5 pens x 0.70)

6.45 + 3.50 = 9.95

(6 pens x 0.70) + (6 erasers x 0.89)

4.20 + 5.34 = 9.54

(1 pen × 0.70) + (4 notebooks × 2.35)

0.70 + 9.40 = 10.10

(3 folders × 1.29) + (7 erasers × 0.89)

3.98 + 6.23 = 10.21

(4 folders × 1.29) + (2 notebooks × 2.35)

5.16 + 4.70 = 9.86
