Answer:
225 feet farther.
Step-by-step explanation:
This question can be solved using rules of three.
Up the river in 5 minutes:
You kayak up a river at a rate of 192 feet every 2 minutes. That is, a rate of 192/2 = 96 feet per minute.
So in 5 minutes, you will kayak 96*5 = 480 feet up the river.
Down the river in 5 minutes:
You kayak down a river at a rate of 423 feet every 3 minutes. That is, a rate of 423/3 = 141 feet per minute.
So, in 5 minutes, you will kayak 141*5 = 705 feet down the river.
How much farther do you kayak in 5 minutes on the way down the river than in 5 minutes on the way up the river.
706 - 480 = 225 feet farther.
Answer:
y=3x^2,y=5^2,y=7x^2
Step-by-step explanation:
y=3x^2 is the widest, y=7x^2 is the narrowest, which leaves y=5x^2 in the middle
D = square root [<span>(<span>x2</span>−<span>x1</span><span>)^2</span>+(<span>y2</span>−<span>y1</span><span>)^2]
</span></span>D = square root [(5−1)^2+(6−1)^2]
D = square root [4^2+5^2]
D = square root [16+25]
D = square root [41]
D = 6.4
answer is <span>C. 6.4 units</span>
