For number three they are all equal
Answer:
the center: (-3; 2)
the radius: √65
the equation of the circle: (x + 3)² + (y - 2)² = 65
Answer:
<em>Both lights will blink at the same time 12 times in 3 minutes</em>
Step-by-step explanation:
<u>Greatest Common Factor (GCF)
</u>
The greatest common factor of a set of numbers is the largest positive integer that divides exactly into all numbers. For example, 24 is the GCF of 6 and 8 because there is no smaller number who divides both numbers with zero-remainder.
We know two neon lights blink every 6 seconds and 8 seconds respectively. It means they coincide every 24 seconds. Thus it's only a matter of know how many times we can count 24 seconds in 300 seconds. We can easily find it by dividing 300/24=12.5
So both lights will blink at the same time 12 times in 3 minutes
First differences are ...
41 -39 = 2
43 -41 = 2
45 -43 = 2
These are all the same, so 2 is the common difference of the arithmetic sequence beginning with 39.
The Nth term is
The problem statement seems to ask for the 10th term and for a15. Here they are.
