Answer:
8(5) + 8(25) + 8(125) + 8(625) +8(3125)= 10(3125 - 1)=31240
Hence proved Conjecture is correct
L.H.S=R.H.S
Step-by-step explanation:
Consider the pattern:
8(5)=10(5-1)=40
8(5) + 8(25) = 10(25 - 1) =240
8(5) + 8(25) + 8(125) = 10(125 - 1) =1240
8(5) + 8(25) + 8(125) + 8(625) = 10(625 - 1)=6240
According to inductive reasoning next term of pattern will become:
8(5) + 8(25) + 8(125) + 8(625) +8(3125)= 10(3125 - 1)=31240
Checking whether conjecture is correct or not:
Consider L.H.S:
8(5) + 8(25) + 8(125) + 8(625) +8(3125)
40+200+1000+5000+25000
31240
R.H.S:
31240
Hence proved Conjecture is correct
L.H.S=R.H.S
Answer: 31.5
Concept:
When encounter questions that ask for operation on algebraic expressions, using BODMAS or PEMDAS method would be easier. Since this question asked for using BODMAS, then it is:
- Bracket
- Order
- Division
- Multiplication
- Addition
- Subtraction
Solve:
<u>Given</u>
2 × 3 + 45 ÷ 2 - 6 + 9
<u>Simplify by division</u>
=2 × 3 + 22.5 - 6 + 9
<u>Simplify by multiplication</u>
=6 + 22.5 - 6 + 9
<u>Simplify by addition</u>
=28.5 + 9 - 6
=37.5 - 6
<u>Simplify by subtraction</u>
=31.5
Hope this helps!! :)

Answer:
B) 4/5
Step-by-step explanation:
The cosine of one of the angles is the same as the sine of the other angle.
In this case, the cos(M) = 4/5, and the sin(K) is also 4/5.
