Answer:
Amount of paper need = 140 cm²
Step-by-step explanation:
Given:
Length of rectangular prism = 5 cm
Width of rectangular prism = 5 cm
Height of rectangular prism = 4 cm
Base of triangular side = 5cm
Height of triangular side = 6 cm
Find:
Amount of paper need
Computation:
Amount of paper need = Curved surface area of rectangular prism + Curved surface area of square pyramid
Amount of paper need = 2h(l + b) + 4[Area of triangle]
Amount of paper need = 2h(l + b) + 4[(1/2)(b)(h)]
Amount of paper need = (2)(4)(5 + 5) + 2[(5)(6)]
Amount of paper need = (8)(10) + 2[30]
Amount of paper need = 80 + 60
Amount of paper need = 140 cm²
Answer:
Continuous
Step-by-step explanation:
We want to expand (2x + y²)⁵.
From Pascal's Triangle (shown below), the coefficients of the expansion are
1,5,10,10,5,1.
n=0: 1
n=1: 1 1
n=2: 1 2 1
n=3: 1 3 3 1
n=4: 1 4 6 4 1
n=5: 1 5 10 10 5 1
Therefore the third term in the expansion is
10*(2x)³*(y²)² = 10*(8x³)*(y⁴) = 80x³y⁴
Alternatively, the third term is
₅C₃ (2x)³(y²)² = 10*(8x³)*(y⁴) = 80x³y⁴
Answer: 80x³y⁴
Answer:
look at my explanation
Step-by-step explanation:
Find the area of two sides (Length*Height)*2 sides. Find the area of adjacent sides (Width*Height)*2 sides. Find the area of ends (Length*Width)*2 ends. Add the three areas together to find the surface area
