The third one is greater than 7
The fourth one is greater than or equal to
Answer: The correct option is 1, i.e., 
.
Explanation:
The geometric sequence is in the form of,
Where, a is the first term of the sequence and r is the common ratio of the sequence.
It means the 
term of the sequence is defined as,
So the the 
term of the sequence is defined as,
It means the geometric sequence is in the form of,
Where, r be any constant.
From the options only is in the form of with common ratio 
.
Therefore, the function can be used to model the graphed geometric sequence is .
Slope is 9 or 9/1 and the y-intercept is -9 or (0,-9)
Distance = speed x time
Distance travelled by car A when car B started = 60 x 2 = 120 miles
Number of miles remaining at the time car B started = 400 - 120 = 280 miles.
At time of their meeting both cars has travelled a combined distance of 280 miles and has spent the same time.
Let t be the time they travelled together before they meet, then the sum of the distance travelled by car A and car B is 280miles.
60t + 80t = 280
140t = 280
t = 280/140 = 2 hours
After 2 hours car A has travelled a further 60 x 2 = 120 miles and car B has travelled 80 x 2 = 160 miles.
Total distance travelled be car A is 120 + 120 = 240 miles
Midpoint of the journey = 400/2 = 200 miles
Therefre, at the time they met, the were 40 miles from the midpoint and they are close to San Francisco.
Hello.
To find the answer you will have to add them then divide by 2.
So if you add 21.85+-4.7 you will get the answer of 17.15.
Then divide by two to get 8.575
The answer is: 8.575 Celsius
Have a nice day
