First, graph each point on the coordinate plane.
Now think of a vertical line moving from left to right. The line is always vertical. It starts at the left of the graph and moves to the right. If at any time, the line intersects more than one point, then the relation is not a function. If all the x-coordinates are different, the vertical line cannot touch more than one point at a time.
Answer:
x= all real numbers
y= all real numbers
Step-by-step explanation:
Answer:
3 in wide by 4.5 in long.
Step-by-step explanation:
3/4=0.75
I divided the given dimensions by two, so I could multiply .75 by the sets of twos instead of dividing 3/4 by two and multiplying that by 12 and 8.
.74 x 4 = 3
.75 x 6 = 4.5
Answer:
Volume of the cone is increasing at the rate .
Step-by-step explanation:
Given: The radius of a right circular cone is increasing at a rate of in/s while its height is decreasing at a rate of in/s.
To find: The rate at which volume of the cone changing when the radius is in. and the height is in.
Solution:
We have,
, , ,
Now, let be the volume of the cone.
So,
Differentiate with respect to .
Now, on substituting the values, we get
Hence, the volume of the cone is increasing at the rate .
