Answer:
1.2
Step-by-step explanation:
Output of f, which also means f(x), when x = -6 is 1.2.
Using the graph given, this implies that, when x = -6, the corresponding value of f(x) will give us 1.2.
Thus:
f(-6) = 1.2 =>> (-6, 1.2).
Answer:
Average speed
= 5 5/6 mph , or
= 5.83 mph (to 2 decimals)
Step-by-step explanation:
Average speed is total distance divided by the total time it takes to cover the given distance.
Since uphill = 5 mph, and downhill = 7 mph, we know the average speed is between 5 and 7 mph.
Let
x = distance uphill, and also distance downhill.
Total distance = 2x miles
Total time = x/5 + x/7 hours = 12x/35 hours
Average speed
= total distance/total time
= 2x / (12x/35) mph
= 70x / 12x
= 5 5/6 mph
= 5.83 mph (to 2 decimals)
No of coins Sparrow had in the beginning 92 coins
Step-by-step explanation:
Total coins = 210
Current ratio = 4:5:6
It implies 210 needs to be split into 15 parts (4+5+6)
So, each part = 210/15 = 14 coins
Again which implies 14*4 : 14*5 : 14*6 = 56 : 70 : 84
So before the game began,
No of coins Ahab had = (56 - 5) = 51
No of coins Davy had = (84 - 7) = 67
Hence, No of coins Sparrow had = (210 - 51 - 67) = 92 coins
Answer:
18
Step-by-step explanation:
50 - 32 = 18
