Answer:
it is B
Step-by-step explanation:
Answer:
This is an geometric sequence with a common ratio <em>r</em> of 1/2
Step-by-step explanation:
When you find out <em>r</em>, you realize the ratio between the numbers to be dividing by 2, or 1/2. Since it is <em>r</em> and not common difference <em>d</em>, it is an geometric sequence.
Answer: 5:1
Step-by-step explanation:
15 divided by 3 is 5, and 3 divided by 3 is 1
The temperature 6 hours after day break is 53 degrees
Step-by-step explanation:
The temperature was 65 degrees at daybreak. Then it dropped two degrees per hour until dusk. This decrease in temperature can be modeled by the equation,
y = -2x + 65
according to this equation
y= temperature after day break
x= no of hours ( in this case 6)
So equation becomes
y= -2 (6) +65
y= 65- 12
y= 53 degrees
So the temperature 6 hours after day break is 53 degrees
