It'd be easier to do #18 if y ou were to break it up:
14* (first term + 14th term)
Sum from n=1 to 14 of n = S = ---------------------------------
14 2
14(1+14)
= ---------------- = 7(15) = 105
2
The sum of twice that is 210. The sum of "1 from n=1 to n=14" is just 14.
The final sum is 210 + 14 = 224 (answer)
Answer: ok fine
Step-by-step explanation:
Answer:
Inequality to represent given data is y ≥ 5.
No, y = 4 is not a solution, since 4 is not a value that falls within the domain of the solutions for the inequality.
Step-by-step explanation:
Enter an inequality that represents the phrase the sum of 1 and y is greater than or equal to 6. The inequality is y = 4 a solution.
i) therefore y + 1 ≥ 6
ii) therefore y ≥ 5
iii) No, y = 4 is not a solution, since 4 is not a value that falls within the domain of the solutions for the inequality.
Answer:
$3714.18
Step-by-step explanation:
From the question;
Amount invested is $3300
Rate of interest 3% per year compound interest
Time is 4 years
We want to determine the amount that accrued after 4 years
In this case we are going to use the compound interest formula;
That is;
where A is the amount, P is the principal , r is the rate of interest and n is the time taken.
Therefore;

= $3714.18
Therefore, the amount accrued after 4 years is $3714.18
