Answer:
The first graph is of the sequence defined by the given function.
Step-by-step explanation:
Given the graph of sequence defined by the function
when the first term is in the sequence is 375 i.e f(1)=375
Hence, in coordinate points becomes
(1,375), (2,225), (3,135), (4,81)
∴ The first graph is of the sequence defined by the given function.
Answer: the average speed coming home is 63.3 mph
Step-by-step explanation:
Let x represent your average speed while you were going home.
Distance = speed × time
It took me 3 hours to visit my friend in Maine, averaging a speed of 58 miles per hour. This means that the distance travelled on your way to your friend's house is
3 × 58 = 174 miles
If it took me 15 minutes less to get back home, it means that the time you spent in going back home is 3 - 0.25 = 2.75hours
Distance covered while going back home is
2.75 × x = 2.75x
Assuming the distance is the same, it means that
2.75x = 174
x = 174/2.75
x = 63.3 mph
Answer:
C
Step-by-step explanation:
Answer: the watermelon costs $1 and the honeydew melon costs $3.
x = honeydew costs y = watermelon cost
3x+7y = 16
3(3)+7(1) = 16
9+7 = 16
7x+4y = 25
7(3)+4(1) = 25
21+4 = 25
