Hello!
your three answers are:
the maximum height of the rock occurs at x=0 because the y intercept always is at x=0, and the starting point is the y intercept
the rock is in the air for 3 seconds because x goes to a max of 3
the maximum height of the rock is 45 feet because y, or height, starts at 45, and ends at 0
I hope this helps, and have a nice day!
Answer:
solution given:
volume of lower one[V1]=l×b×h=1.5×0.5×0.5=0.378m³
volume of upper one [V2]=l×b×h=1×0.5×(0.75-0.5)=
0.125m³
total volume=V1+V2=0.378m³+0.125m³=0.503m³
0.503m³ is your answer
In order to determine the volume of a cylinder, the radius and height must be known. The radius is present in the question but the height isn't. To find the volume of a cylinder you would need to use the formula V = πr²h.
