For this case we have an equation of the form:
y = A * (b) ^ t
Where,
A: initial amount
b: decrease factor
t: time
Substituting values:
y = 30 * (b) ^ t
To calculate t we use a point in the table.
We have:
(t, y) = (1, 28.5)
Substituting:
28.5 = 30 * (b) ^ 1
b = 28.5 / 30
b = 0.95
Answer:
a. Decay factor is 0.95
B) {19,16,50,18,29,23,37}
Answer:
-49 275/1000
Step-by-step explanation:
The length would be 90 cm. For every 1 cm of actual size it will be increased by 9. So.....10 x 9 = 90 cm.
1/2 was broccoli and 1/2 was mushroom...
he ate 2/3 of the broccoli part......2/3 of 1/2 = 2/3 * 1/2 = 2/6 = 1/3
he ate 1/4 of the mushroom part....1/4 of 1/2 = 1/4 * 1/2 = 1/8
so he ate 1/3 + 1/8 = 8/24 + 3/24 = 11/24 <==
