Step-by-step explanation:
3^-n=0.2
1/3^n=0.2
1=0.2(3^n)
3^n=1/0.2
3^n=5
(3^n)²=5²
(3^n)²=25
Volume of cone is 10
if the radius is r and height is h
while volume of cylinder is pi r 2nd power h,
volume of cone is 1/3 pi r 2nd power h.
hence with same r and h the volume of cone is one-third of that of cylinder and hence
volume of cone is 10.
Answer:
A
Step-by-step explanation:
Answer:
I believe it is the first picture because the equation goes with the line.
Step-by-step explanation: The yellow/orange line shows that it is negative (because of the -x slope). In the second picture the yellow/orange line shows a positive line that does not match the equation "y=-x+2"
Answer:
A direct variation is when x and y (or f(x) and x) are directly proportional to each other... For example, if you have a chart that says x and y, and in the x column is 1, 2 and 3, and the y column says 2, 4 and 6... then you know it's proportional because for each x, y increases by 2
