Julieta has a job for $49000 which increases at the rate of 3% per year, so the money earned after 21 years is $79870.
What is Simple interest?A quick and simple way to figure out interest on that money is to use the simple interest approach, which adds interest at the same rate for each daily cycle, and it is to the initial principal amount.
A way to figure out how much interest will be charged on an amount of money at a specific rate and for a specific duration of time is by using simple interest.
As per the information received from the question,
Principle amount, P = $49000
Rate, R = 3%
Time, T = 21 years.
SI = ($49000 × 3 × 21)/100
SI = 30870
So, the total amount earned in 21 years is $30870, and the total money he is having after 21 years is $79870.

The sum of an arithmetic series where t1 = -2, t3 = 7, and n = 15 is
The sum of the arithmetic series with the parameters t1 = -2, t3 = 7, and n = 15 is 442.5
How to determine the sum of the series?The given parameters are:
t1 = -2
t3 = 7
n = 15
Start by calculating the common difference using:
Tn = t1 + (n- 1)d
So, we have:
7 = -2 + (3 - 1) * d
Evaluate
7 = -2 + 2d
Add 2 to both sides
2d = 9
Divide by 2
d = 4.5
The sum is then calculated using:
[tex]S_n = \frac n2 * (2a + (n - 1) * d)[/tex]
So, we have:
[tex]S_{15} = \frac {15}2 * (2*-2 + (15 - 1) * 4.5)[/tex]
Evaluate
[tex]S_{15} = 442.5[/tex]
Hence, the sum of the arithmetic series is 442.5

a =14.6 rounded to 1 DP
b= 3.25 rounded to 2 DP
Find the maximum of a - b
Answer:
11.405
Step-by-step explanation:
When rounding numbers, check the digit to the right of the one you're rounding to:
If it is 0, 1, 2, 3 or 4 round downIf it is 5, 6, 7, 8 or 9 round upIf a = 14.6 is rounded to 1 decimal place then:
minimum value of a = 14.55 (rounds up to 14.6)maximum value of a = 14.649999... (rounds down to 14.6)If b = 3.25 is rounded to 2 decimal places then:
minimum value of b = 3.245 (rounds up to 3.25)maximum value of b = 3.2549999... (rounds down to 3.25)Therefore, to find the maximum value of a - b, subtract the smallest value of b from the largest value of a:

The fourth term of an arithmetic sequence is 20, and the 13th term is 65. Find the sum of the first 13 terms
Answer:
S₁₃ = 455
Step-by-step explanation:
the sum to n terms of an arithmetic is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
We require to find both a₁ and d
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
given a₄ = 20 and a₁₃ = 65 , then
a₁ + 3d = 20 → (1)
a₁ + 12d = 65 → (2)
subtract (1) from (2) term by term to eliminate a₁
9d = 45 ( divide both sides by 9 )
d = 5
substitute d = 5 into (1) and solve for a₁
a₁ + 3(5) = 20
a₁ + 15 = 20 ( subtract 15 from both sides )
a₁ = 5
Then
S₁₃ = [tex]\frac{13}{2}[/tex] [ (2 × 5 ) + (12 × 5 ) }
= 6.5 (10 + 60)
= 6.5 × 70
= 455
