Answer:
7m^2 - 11m - 2
Step-by-step explanation:
Subtract (-3m^2 + 10m + 4) from 4m^2 - m + 2:
4m^2 - m + 2
- (-3m^2 + 10m + 4) Now distribute the negative sign:
4m^2 - m + 2
+ 3m^2 - 10m - 4
--------------------------
7m^2 - 11m - 2 is the final answer.
The term "exponential growth" refers to a very rapid increase in number while the term "exponential decay" refers to a very rapid decrease in number.
<h3>Exponential growth</h3>
The "exponential" typically connotes something that happens very rapidly. Hence, it is safe to say that a suitable synonym for the word "exponential" is the word "rapid".
Hence, "exponential growth" refers to a very rapid increase in number while the term "exponential decay" refers to a very rapid decrease in number.

Answer:
0.606531 = 60.6531% probability that it will take between 2 and 132 minutes for the student to arrive at the library parking lot.
Step-by-step explanation:
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following equation:
In which 
is the decay parameter.
The probability that x is lower or equal to a is given by:
Which has the following solution:
The probability of finding a value higher than x is:
Mean of 4 minutes
This means that 
Find the probability that it will take between 2 and 132 minutes for the student to arrive at the library parking lot:
This is:
In which
0.606531 = 60.6531% probability that it will take between 2 and 132 minutes for the student to arrive at the library parking lot.
30 × 5 = 150
150 - 110 = 40
40 ÷ 2 = 20
