Answer:
65 calories=15 minutes
Find how many minutes it will take Paul to born 1 calory. You divide 65 by 15
65÷15=4.333
Find how many calories lost in 1 hour= 60 minutes multiply by 4.3
60*4.333=260 calories
Therefore,
Paul burns 260 calories in 1 hour

Yes that a good answer...
Answer:
f(-6) = 3
Step-by-step explanation:
In order to find the value of f(-6), we need to find what y-value appears associated with x = -6 according to the graph resented.
Therefore, go to x = -6 on the horizontal axis (six units to the left of the origin of the coordinate system), and find at what value of the y-axis the vertical grid passing through x = -6 intercepts the graph of the function.
That is indicated by a red dot in the attached image.
We see therefore that for x = -6 the y-value that the graph of the function shows in the vertical scale is "3".
Then, f(-6) = 3
The equation of a circle is:
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the location of the center and r is the radius. So we need to find h, k, and r. The center is given as (5,-4) so h = 5 and k = -4:
(x-5)^2 + (y-(-4))^2 = r^2
(x-5)^2 + (y+4)^2 = r^2
So we need to find r. Use the distance formula to find the distance between (5,-4) and (-3,2):
r = [(5-(-3))^2+((-4)-2)^2]^1/2
r = [8^2 + (-6)^2]^1/2
r = [64 + 36]^1/2
r = 100^1/2
r= 10
The final equation is:
(x-5)^2 + (y+4)^2 = 10^2
