Answer:
If a system has infinitely many solutions, then the lines overlap at every point. In other words, they're the same exact line! This means that any point on the line is a solution to the system. Thus, the system of equations above has infinitely many solutions.
Step-by-step explanation:
Answer: g is a geometric sequence.
Step-by-step explanation:
Each year since then, her account accumulated interest amounting to
15% of the balance in the previous year.
15% = 15/100 = 0.15
Since the balance is increasing each year, then the constant factor by which it is increasing is 1 + 0.15 = 1.15.
This factor of 1.15 is a common ratio. This means that the sequence is a geometric sequence since it is increasing by a common ratio.
Answer:
A = 12.56 m²
General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
<u>Geometry</u>
- Area of a Circle: A = πr²
- d = 2r
Step-by-step explanation:
<u>Step 1: Define</u>
d = 4 m
<u>Step 2: Find </u><em><u>r</u></em>
- Substitute: 4 = 2r
- Isolate <em>r</em>: 2 = r
- Rewrite: r = 2 m
<u>Step 3: Find Area</u>
- Substitute: A = π(2)²
- Substitute: A = (3.14)(2)²
- Evaluate: A = (3.14)(4)
- Multiply: A = 12.56 m²
Answer:
A
