The graph crosses the x axis where g(x) = 0 , so:-
x^2 - 5 = 0
x^2 = 5
x = sqrt5 or -sqrt5
so grapg corosses the x axis at (-sqrt5,0) and (sqrt5, 0)
Answer:
6
Step-by-step explanation:
2(y+1)
y=2
2+1= 3
2(3)
u multiply it
and u get 6
We are required to find the volume of the object which comprises of a cylinder and a cone
The volume of the object is 108 in³
Volume of a cylinder = πr²h
π = 3
r = diameter / 2 = 4 in / 2 = 2 in
h = 8 in
Volume of a cylinder = πr²h
= 3 × (2 in)² × 8 in
= 3 × 4 in² × 8 in
= 96 in³
Volume of a cone = πr²h/3
= (3 × (2 in)² × 3 in) / 3
= (3 × 4 in² × 3 in) / 3
= 36 in³ / 3
= 12 in³
The volume of the object can be found by adding the volume of the cylinder and the volume of the cone
Total volume = Volume of a cylinder + Volume of a cone
= 96 in³ + 12 in³
= 108 in³
