g 78 degress
Step-by-step explanation:
Answer: c= 14 * t
Explanation:
The first day:
280/20= 14
Second day:
490/35= 14
That is how it does not change from day to day, the average is 14 calories per minute,therefore, the equation would be:
c= 14 * t
Answer:
or 1.9099
Step-by-step explanation:
Look for y values at each of those given values of "x" and apply the slope formula. When x = pi. y = -1 so the coordinate is 
. When x = 3pi/2, y = 2 so the coordinate is 
Plug those values into the slope formula:
You need a common denominator of pi:
Do the math on that to get a slope of 
Answer: yes, it is
Step-by-step explanation:
A number is divisible by 6 if it is divisible by 2 and 3 simultaniously.
n = k(k+1)(k-1)
If k-1 is a multiple of 3, n is divisible by 3, so one of the requirements is ok.
Now, if k-1 is a multiple of 3, it can be even or odd.
if k-1 is even, then it is divisible by 2 and as it is divisible by 3 as well, n is divisible by 6
if k-1 is odd, then k and k+1 is even, hence, divisible by 2.
As n = k(k+1)(k-1), n is also divisible by 6.
