Answer:
16,500
Step-by-step explanation:
the 10% of 15,000 is 1,500. to make a profit of 10% you have to sell the bike for 15,000+1,500=16,500
Answer:
10.14 feet per year.
Step-by-step explanation:
Given:
Over the next 3 1/2 years, a tree grew to a final height of 35 1/2 feet.
Question asked:
During those 3 1/2 years, what was the average yearly growth rate of the height of the tree?
Solution:
We can find the average yearly growth rate by using average formula, taking
final height of the tree as sum of observation and time span taken to growth as number of observation:-
As we know:
Thus, during 
, the average yearly growth rate of the height of the tree was 10.14 feet per year
The value of f(15), to the nearest hundredth is 253.88
The standard exponential equation is given as:
If f(4.5) = 16, then;
16 = ab^4.5 ..............1
Similarly, if f(9.5) = 60, then:
60 = ab^9.5 ........................... 2
Dividing both equations will give:
60/16 = ab^9.5/ab^4.5
60/16 = b^9.5-4.5
60/16 = b^5
3.75 = b^5
b = 1.3
Get the value of a. Recall that;
60 = ab^9.5
60 = a(1.3)^9.5
60 = 12.09a
a = 60/12.09
a = 4.96
Get the value of f(15)
f()15 = 4.96(1.3)^15
f(15) = 4.96(51.18)
f(15) = 253.88
Hence the value of f(15), to the nearest hundredth is 253.88
