Given function : 
We need to identify a " initial amount", b "growth factor", r " rate of growth".
We know, exponential growth formula
, where a is initial amount, b is growth factor. On comparing with given function let us find values of a and b.
⇔ .
We can see a= 1.05 and b = 1.46.
Now, b=1+r.
Therefore, 1+r =1.46.
Subtracting 1 from both sides, we get
1+r-1 =1.46-1
r = 0.46.
On converting 0.46 into percentage, we get
0.46 × 100 = 46.
Therefore, intial amount a = a= 1.05 , growth factor b = 1.46, and the rate of growth r= 46%.
Area is length x width, so if length is 6 and area is 18 width is 3, because 6x3 is 18
Answer:
2.4 cups
Step-by-step explanation:
Divide 2 by 5
= 0.4
We have 2 cups of sugar
2 + 0.4 = 2.4 cups.
Answer:
The mean increased
Step-by-step explanation:
The mean is the average, add all numbers and divide by total amount.
Old mean: 6
New mean:8
Time = distance / speed
time = (7/8) / (3/8)
= 7/8 * 8/3
= 7/3 or 2 1/3 minutes or 2 minutes and 20 seconds
