Q: Express 7/16 in decimal form and classify it.
A: Step 1: Divide 7 by 16 using long division. Step 2: 7 ÷ 16 = 0.4375 Step 3: Since decimal terminates, it's a terminating decimal. Answer: 0.4375 (terminating decimal, rational number) Why it terminate
Q: Convert the recurring decimal 0.36̄ to p/q form.
A: Step 1: Let x = 0.363636... Step 2: Multiply by 100: 100x = 36.363636... Step 3: Subtract: 100x - x = 36.363636... - 0.363636... Step 4: 99x = 36 Step 5: x = 36/99 = 4/11 (simplifying by dividing by 9
Q: Find three rational numbers between 2/3 and 3/4 using the mean method.
A: Step 1: First rational = (2/3 + 3/4)/2 = (8/12 + 9/12)/2 = 17/24 Step 2: Second rational = (2/3 + 17/24)/2 = (16/24 + 17/24)/2 = 33/48 = 11/16 Step 3: Third rational = (17/24 + 3/4)/2 = (17/24 + 18/24
Q: Find the degree of the polynomial: 3x⁴ - 5x² + 7x - 2
A: Step 1: Identify the highest power of x in the polynomial. Step 2: Look at each term: 3x⁴ (degree 4), -5x² (degree 2), 7x (degree 1), -2 (degree 0) Step 3: The highest degree is 4. Answer: Degree = 4
Q: If p(x) = 2x³ - 3x + 1, find p(2)
A: Step 1: Substitute x = 2 in the polynomial p(x) = 2x³ - 3x + 1 Step 2: p(2) = 2(2)³ - 3(2) + 1 Step 3: p(2) = 2(8) - 6 + 1 Step 4: p(2) = 16 - 6 + 1 = 11 Answer: p(2) = 11
Q: Find the zero of the polynomial: 3x - 15
A: Step 1: Set the polynomial equal to zero: 3x - 15 = 0 Step 2: Add 15 to both sides: 3x = 15 Step 3: Divide both sides by 3: x = 5 Step 4: Verify: 3(5) - 15 = 15 - 15 = 0 ✓ Answer: x = 5
Q: A line segment AB = 8 cm. If point C is the midpoint of AB, and point D is the midpoint of BC, find the length of AD.
A: Step 1: Since C is midpoint of AB, AC = CB = AB/2 = 8/2 = 4 cm. Step 2: Since D is midpoint of BC, BD = CD = BC/2 = 4/2 = 2 cm. Step 3: AD = AC + CD = 4 + 2 = 6 cm. Answer: AD = 6 cm. (Using Euclid's
Q: Using Euclid's postulates, how many lines can pass through two distinct points A and B?
A: Step 1: Apply Euclid's 1st postulate - 'A straight line can be drawn from any point to any point'. Step 2: This means exactly ONE unique line passes through two distinct points. Step 3: If we assume t
Q: Draw a circle with center O and radius 5 cm. Then draw another circle with center P (where OP = 3 cm) and radius 4 cm. Will these circles intersect?
A: Step 1: Circle 1 has center O, radius = 5 cm. Circle 2 has center P, radius = 4 cm, OP = 3 cm. Step 2: For intersection, check if |r₁ - r₂| < OP < r₁ + r₂. Step 3: |5 - 4| = 1, and 5 + 4 = 9. So 1 < 3
