Find a5, when a1 =4, r=5

Mathematics
1 answer:
sasho [114]3 years ago
3 0

Answer:

Answer: a5 = 2500

Step-by-step explanation:

For a geometric sequence:  

First term = a0  

Second term = a1 = a0*r  

Third term = a2 = a0*r^2  

Fourth term = a3 = a0*r^3  

....  

nth term = a(n-1) = a0*r^(n-1)  

Given: a1 = 4 = a0*r  

Also: r = 5  

So, a0*5 = 4 => a0 = (4/5)  

a5 = a(6-1) = Sixth term = a0*r^5 = (4/5)*5^5 = 2500  


Hope this helps

Pension = 12% of salary
nadya68 [22]

Answer:

Salary = $43,313.40

Step-by-step explanation:

Let his salary be x.

Now we're told that;

Pension = 12% of his salary = 0.12x

Health Insurance = 0.3% of salary = 0.003x

Disability Insurance = 0.4% of salary = 0.004x

Since his total contract with benefits is worth $48,814.20

This means that;

x + 0.12x + 0.003x + 0.004x = 48814.2

1.127x = 48814.2

x = 48814.2/1.127

x = $43,313.40

4-20. When Susan's brother went to college, she and her two sisters evenly
Zigmanuir [339]

Each sibling got 1 poster, 8 CDS and 72 books.

<h3>How the belongings were divided </h3>

Since the belongings were divided equally, each sibling would get the same amount of belongings. In order to determine the belongings each person got, we would divide each possession by 3.

  • Number of poster each person got = 3/3 = 1
  • Number of books each person got = 216
  • Number of CDs each person got = 24 / 3 = 8

First, he needs to run to the store. To get to the store from his apartment, he can walk 1.2 miles North and 0.5 miles East alon
Pachacha [2.7K]

Answer:

If Henry walks along the sidewalks, he will walk 1.7 miles in total. It will take him 17 minutes to reach the store and another 17 minutes to come back.

If Henry cuts through the city, he will walk √(1.2² + 0.5²) = 1.3 miles in total. It will take him 22.3 minutes to reach the store and another 22.3 minutes to come back.

Even though Henry will need to walk a longer distance if he walks along the sidewalks, he will be able to reach the store and back back in a shorter time than if he cuts through the city.
