Answer: S1:E7 ; S2:E1 ; S3:E5
Step-by-step explanation:
What we know:
- 3 answers apply
- We need to find which answers go with each question
**A lot of info is problem-specific.
How to solve:
Since we only need to write the equations, we simply need to find the x and y variables, and the total.
Process:
Problem 1:
- Find the x 5.50
- Find the y 3
- Find the total 145
- Write equation 5.50 + 3 = 145
Problem 2:
- Find the x 2.50
- Find the y 0.75
- Find the total 25
- Write equation 2.50 + 0.75 = 25
Problem 3:
- Find the x 2
- Find the y 5
- Find the total 50
- Write equation 2 + 5 = 50
Solution: S1:E7 ; S2:E1 ; S3:E5
Answer:
- <u>The sum of the series = 198.</u>
<u></u>
Step-by-step explanation:
In the given arithmetic series,
- The first term (a) = 6
- Common difference (d) = (aₙ – aₙ₋₁) = 10 - 6 = 4
- Last term (aₙ) = 38
To find the sum of the series, we need to find the number of terms (n) at first. So,
Now, let's find the sum of the arithmetic series (Sₙ).
- The sum of the series = <u>198</u>.

Answer:
Step-by-step explanation:
$760(1.023) = $777.48
The graph is a circle, centered at the origin, with radius=4.
We know that we can write the equation of a circle with radius r and center (a,b) as :
.
Thus, substituting (a, b) with (0, 0) and r with 4, we have:
.
The solutions of this equation are all the points forming the circle shown in the picture. The solutions of this equation are still the same even if we multiply both sides of the equation by 2, because rewriting the equation as:
,
we would still have the same roots.
Thus, the equation of the circle can be written as :
.
