Answer:

Step-by-step explanation:
Simple interest (I) = $160
Principal amount (P) = $2000
Time period (t) = 8 months
Let R denotes rate of interest.
Relation between simple interest, principal amount, time and rate of interest is given by 

This question is essentially just determining whether you understand the definition of integers and square roots. The square root of a quantity is a number that when multiplied with itself gives that quantity. The square root of 68 is expressed as:
√68 = 8.25
The square root of 68 is roughly 8.25. Now, an integer is simply a whole number, which is a number that is not a fraction. Therefore, the smallest integer that is greater than 8.25 is simply the next whole number, which is 9.
The smallest integer greater than the square root of 68 is 9.
Answer:
1,700
Step-by-step explanation:
The computation of the initial value of the computer is shown below:
Let us assume the value of a certain computer in the first year is X
In the second year, it is 
In the third year, it is 
In the fourth year, it is 
Now it is given that after 3 years, the value of the computer is = 425 i.e equal to

So, X = 1,700
Hence, the initial value of the computer is 1,700
The slope is 4/5 assuming time is along the bottom of the graph.
