Answer:
46 minutes.
Step-by-step explanation:
Running 2 km in 13 minutes translates to 6 minutes and 30 seconds per km.
minutes: 6 x 7 = 42
seconds: 30 x 7 = 210
second part: 210/60 = 3 minutes 30 seconds
adding everything together: 42 minutes + 3 minutes 30 seconds + 45 minutes 30 seconds, rounded equals 46 minutes
The formula for slope is
m = (y2 - y1)/(x2 - x1)
A. m = (5 - 0)/(-2 + 2)
m = (5)/(0)
m = error
B. m = (-2 - 0)/(0 + 2)
m = (-2)/(2)
m = -1
C. m = (2 - 0)/(2 - 0)
m = (2)/(2)
m = 1
D. m = (0 - 0)/(2 - 3)
m = (0)/(-1)
m = 0
the slope that is deemed undefined is the one resulting in an error, which is A
A vacuous proof has been employed. The proposition p(n) states: "if n is a positive integer greater than 1, then n² > n." To prove p(0), it translates to "if 0 is a positive integer greater than 1, then 0² > 0." Since the premise stating that "0 is a positive integer greater than 1" is false, the overall implication holds true. This exemplifies that in vacuous proof, if a statement's premise is false, the implication remains trivially true.
