Answer:
b=130
Step-by-step explanation:
b+(-43)=87
b+(-43+43)=87+43
b=130

The composite figure comprises of a cone balanced on top of cylinder
Step-by-step explanation:
The composite figure is formed from a cone and a cylinder with the same base radius, Let the base radius be r
Then the volume of the cone will be 
Then the volume of the cylinder will be 
The total volume of the composite figure will be V, where
let the height of cone and cylinder be same
The volume of the composite figure will be 
Hence 
Thecomposite figure comprises of a cone balanced on top of cylinder
Answer:
(9 - 3) × (8 ÷ 2) = 6 × 4 = 24
Step-by-step explanation:
One of the solution
Answer: The sequence is geometric
Step-by-step explanation:
In an arithmetic sequence, the consecutive terms differ by a common difference and this difference is linear.
Common difference = given term - the term before it
In geometric progression, the consecutive terms differ by a common ratio this difference is exponential.
Common ratio = given term/the term before it
Looking at the given sequence,
1) d = 6 - - 2 is not equal to - 18 - 6
Therefore, it is not an arithmetic sequence
2) r = 6/- 2 = - 18/6 = - 3
Therefore, it is a geometric sequence.
Answer:
x = 0, 4, -2
Step-by-step explanation:
f (x) = 3x (x – 4) (x + 2)
0= 3x (x – 4) (x + 2)
3x = 0, x-4 =0 , x+2 = 0
x = 0, 4, -2
