C. It should be equal to 48 because that is the total number of games. It should be +33 so you can subtract 33 from both sides to see how many games the football team lost.
Given:
The recursive formulae are:
(a) 
(b) 
To find:
The explicit equation.
Solution:
A recursive formula of an arithmetic sequence is
and f(1) is the first term.
Where, d is the common difference.
The explicit formula is
where, a is first term and d is common difference.
(a)
We have,
Here, first term is 8 and common difference is -2. So, the explicit formula is
Therefore, the explicit formula is .
(b)
We have,
Here, first term is 0 and common difference is 5. So, the explicit formula is
Therefore, the explicit formula is .
Answer:
Your answer is: No solution
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Step-by-step explanation:
Hope this helped : )
Subtract 0.2 by both sides and the your answer is f = -3.2
Answer:
- <em>The larger merry-go-round's platform is </em><u> 151m² </u><em> larger than the smaller merry-go-round's platform.</em>
Explanation:
The<em> area </em>of a round shape is equal to the area of a circle.
The formula for the area of a circle is:
Then, use that formula for each merry-go-round.
<em><u>1. First merry-go-round</u></em>
<em />
- radius = diameter / 2 = 13m / 2 = 6.5m
- area = π (6.5m)² = 3.14 × (6.5m)² = 132.665m²
<em><u>2. Second merry-go-round</u></em>
- area = π (9.5m)² = 3.14 × (9.5m)² = 283.385m²
<u />
<u>3. Difference of the areas</u>
<u />
- Larger area - smaller area = 283.385m² - 132.665m² = 150.72m²
- Round to the nearest whole number: 151m².
Hence, the larger merry-go-round's platform is 151m² larger than the smaller merry-go-round's platform.
