45 divided by 3 will give you 15 mins per mile
K=2 is the correct answer
The equation for a circle is x^2+y^2=r^2 so the radius is the square root of 16 which is 4. Then you take y-2 and set it equal to 0. This gives you y=2 as the y coordinate of the center. You then set x+4 equal to 0 which gives you x=-4 which is the x coordinate of the center. So the radius is 4 and the center is at (-4,2)
Answer: n^2+5n+4r+7
Step-by-step explanation:
Hello from MrBillDoesMath!
Answer:
t = 135 is on example
Discussion:
Consider t = 135 (degrees)
sin(t) = + Sqrt (2)/2
cos(t) = - Sqrt(2)/2
tan(t) = -1
Visualization: 135 is in second quadrant where sin ("y component') is positive and cos ("x component") is negative. This implies that ratio ( or tan(t) ) is also negative.
Thank you,
MrB
