Answer:
-6n+20
Step-by-step explanation:
The given term of sequece is 14, 8, 2, -4, …,
Here the first term is 14 and then the terms are decreasing by 6 each time because 
As we know that the nth term of the sequence is given by the formula

If n is a term of the given sequence sequence, then its value is -6n+20
Y=36
it basically says y=(9-3)^2
which is y=6^2
which is then y=36
Answer:
x≤9/2
Step-by-step explanation:
8x+15≤51
Subtract 15
8x+15-15≤51-15
8x+≤36
Divide by 8
8x/8≤36/8
x≤9/2
Answer:
2094.4 cm³
Step-by-step explanation:
The volume of a cone =πr²h/3
Where
r = radius = Diameter/2
Diameter = 20cm, radius = 20cm/2 = 10cm
Height = 20cm
Volume of a cone = π × 10² × 20/3
Volume of a cone = 2094.3951 cm³
Approximately to the nearest tenth = 2094.4 cm³
Therefore , the volume of a cone = 2094.4 cm³
