Area of the figure shaded in yellow = 2 x 3 + 2 x 6 = 18 cm²
Total Surface Area = 18 + 18 + (4 + 3 + 2 + 3 + 2 + 6) x 3 = 96 cm²
Answer: 96 cm²
Answer:
18.7
Step-by-step explanation:
Answer:
Step-by-step explanation:
(f - g)(x) = x - 3
Line up these functions vertically:
f(x) = 3x - 2
-g(x) = -(2x + 1)
--------------------
(f - g)(x) = x - 3 (answer)
Answer:
The amount of metal recovered at the eight pass is approximately 4.27 kg
Step-by-step explanation:
The mass of metal recovered formed the following geometric sequence;
32 kg, 24 kg, 18 kg, 13.5 kg
∴ The first term, a = 32 kg
The common ratio in the geometric sequence is found as follows;
r = a·r/a = 24 kg/(32 kg) = 0.75
r = a·r²/a·r = 18 kg/(24 kg) = 0.75
r = a·r³/a·r² = 13.5 kg/(18 kg) = 0.75
The mass of the metal recovered in the eight pass will be the 8th term of the geometric series given as follows;
nth term = a·rⁿ⁻¹
a = 32, r = 0.75, n = 8
∴ 8th term = 32·(0.75)⁸⁻¹ = 32·0.75⁷ = 2187/512 ≈ 4.27
The amount of metal recovered at the eight pass ≈ 4.27 kg.
Answer:
The complete area of the given figure is 
Step-by-step explanation:
Total number of rows = 2
Squares in each row = b
So, the total number of squares in 2 rows = 2 x ( Squares in 1 row ) = 2 x b
Also, side length of 1 square = b cm
As we know, AREA OF SQUARE = SIDE x SIDE
So here, area of 1 square = Side x side = b cm x b cm = 
⇒ The area of total (2b) squares = 2 b x ( Area of 1 square)
Hence, the complete area of the given figure is
