Answer:
(1) {-1/4, 0, 3}
Step-by-step explanation:
Step 1: Factor left side of equation.
2x(4x+1)(x−3)=0
Step 2: Set factors equal to 0.
2x=0 or 4x+1=0 or x−3=0
x=0 or x= −1/4 or x=3
86. Is a negative slope because it slants down from left to right.
87. Is positive slope because it slants up from left to right.
88. Is an undefined slope because it is vertical.
89. Is has a slope of zero because it is horizontal.
Answer:
A), B) & D).
Step-by-step explanation:
Answer:

Step-by-step explanation:
Given:
From the given figure.
Cone height = 7 mm
Cylinder height = 5 mm
Base radius of the cylinder = base radius of the cone = 3 mm
The volume of the given figure is
Volume = volume of cylinder + volume of cone-----------(1)
The volume cylinder is.
----------(2)
Where: r = radius of the cylinder, h = height of the cylinder.
Put the value of height and radius of the cylinder in equation 2.



The volume of the cylnder is
The volume cone is.
--------------(3)
Where: r = base radius of the cone, h = height of the cone.
Put the value of height and base radius of the cone in equation 3.




The volume of the cone is
.
Put the value of the volume of cone and cylinder in equation 1.


Therefore, the volume of the given figure is
