A snail can crawl at a rate of 6 cm in 0.75 minutes. Which representation shows the distance a snail can travel at this rate?
Bogdan [553]

Answer: 0.00133m/s

Step-by-step explanation:

Given

distance crawled by the snail = 6cm = 0.06m

Time taken = 0.75minutes = 0.75*60

Time taken = 45secs

Required

constant rate of change of the snail's crawl (speed)

Speed of the snail = distance/time;

Speed of the snail = 0.06/45

Speed of the snail = 0.00133m/s

Hence the constant rate of change of the snail's crawl in m/s is 0.00133m/s

What is the slope of a this perpendicular line 0=-15-7x+3y? Explain?
Triss [41]
Put it into slope intercept form y=mx+b where m is slope

0=-15-7x+3y
subtract 3y from both sides
-3y=-7x-15
multiply both sides by -1
3y=7x+15
divide both sdies by 3
y=7/3x+5
slope is 7/3

to find a line perpendicular to it, the slope of the other line, when multiplied by this line, must equal -1, exg
1/2 and -2/1 are perpenicular
-1 and 1 are perpendicular

therefor the line perpendicular to it has a slope of -3/7, exg y=-3/7+3
