Given:
f(x) is an exponential function where f(3) = 18 and f(7.5) = 60.
To find:
The value of f(12), to the nearest hundredth.
Solution:
Let the exponential function be
...(i)
It is given that . Substitute in (i).
...(ii)
It is given that . Substitute in (i).
...(iii)
Divide (iii) by (ii).
Putting in (ii), we get
Putting and in (i), we get
Putting x=12, we get
Therefore, the value of f(12) is about 200.00.
The car is travelling at 90 kilometers per hour (90 kmph)
What is the car's speed in kilometers per minute?)
We know 1 hour = 60 minutes,
90 km / 60 minutes = 1.5 kilometers per minute
<em>The speed of the car is 1.5 kilometers per minute
</em>
How many kilometers will the car travel in 15 minutes?)
We know that the car travels 1.5 kilometers in 1 minute. So in 15 minutes:
1.5 kilometers * 15 minutes = 22.5 kilometers
The car will travel 22.5 kilometers in 15 minutes.
Answer:
They are all greater than 1.
Step-by-step explanation:
12+23=35
13+18=31
14+25=39
15+110=125
The median is 73 and the mean is 60.6 (rounded to the nearest tenth). Mean better describes the typical number of points scored.
Answer:
9 3/4 in a percent is 975%.
If you change 9 3/4 into a decimal, it will be 9.75, and 9.75 converted into a percent is 975%
