The answer is the first one, 1,215
Answer:
Recursive Formula: f(1) = 10, f(n) = f(n − 1) + 7 for n ≥ 2.
Explicit Formula: f(n)= 10+7(n-)
Step-by-step explanation:
Recursive Formula: f(1) = first term, f(n) = f(n − 1) + d for n ≥ 2.
Explicit Formula: f(n)= f(1)+d(n-1)
Answer: x² + 5x = 3
Step-by-step explanation:Step-by-step explanation:
The rectangle has been divided into a square and three rectangles.
The area of
a square = (x)(x) = x²
a rectangle #1 = (2)(x) = 2x
a rectangle #2 = (3)(x) = 3x
a rectangle #3 = (2)(3) = 6
The area of a large rectangle is the sum of the square area and three rectangles, and is 9 cm². Therefore we have the equation:
x² + 2x + 3x + 6 = 9 subtract 6 from both sides
x² + 5x + 6 - 6 = 9 - 6
x² + 5x = 3
365 days in a year
21 900 hours in a year * 60
1 314 000 minutes a year * 60
3 600 000 / 1 314 000 = 2.73972602739726
