Answer: First option is correct.
Step-by-step explanation:
Since we have given that
4.05, 1.35, 0.45, 0.15, ...
Since it is a geometric sequence.
So, here, a = 4.05
r =
So, we know the formula for nth term in geometric sequence.
Hence, First option is correct.
Answer:
Company will hire 3 Engineers of Level 1 and 10 Engineers of level 2.
Step-by-step explanation:
Let the number of engineers for level 1 be x.
Let the number of engineers for level 2 be y.
Given:
Total Number of engineers company can hire = 13
Now Total number of engineers are equal to sum of number of engineers for level 1 and number of engineers for level 2.
Hence Framing in the equation form we get;
Also Given:
Salary of level 1 engineers = $45,000
Salary of level 2 engineers = $65,000
Total Budget of Company = $785,000
But Total Budget of Company depends upon the sum of Salary of level 1 engineers multiplied with number of level 1 engineers and Salary of level 2 engineers multiplied with number of level 2 engineers.
Hence equation can be framed as;
Dividing by 5000 on both side we get;
Now Multiplying equation 1 by 9 we get;
Now Subtracting equation 3 from equation 2 we get;
Now Substituting the value of y in equation 1 we get
Hence Company will hire 3 Engineers of Level 1 and 10 Engineers of level 2.
