Answer: y= -1/3x+1 Explanation: we can take any points from graph that intersect with the line and find the slope. take (3,0) (0,1) to find the slope subtract y-es and x-es 1-0/0-3 -1/3 is the slope y=kx+b is the form of linear equation, where k is the slope, hence, y=-1/3x+b put any points from the line to this equation. for example - (3,0) 0=-1/3*3+b 1=b ( b is y intercept) so our equation is y=-1/3x+1 Hipe it helps! if you have questions, you can ask!:):)
Doubling the radius of this cylindrical barrel would quadruple the volume.
Step-by-step explanation:
The volume of a cylinder of radius and height is:
.
If radius stays the same, volume would be proportional to height . That is, . Doubling height would only double .
If height stays the same, volume would be proportional to , the square of the radius. That is, . Doubling radius would quadruple and thus quadruple as required.
