Explanation

Let the two consecutive odd numbers be x and x + 2.

Given x² + (x + 2)² = 394:

x² + x² + 4x + 4 = 394

2x² + 4x - 390 = 0

x² + 2x - 195 = 0

(x + 15)(x - 13) = 0

x = -15 or x = 13

For x = 13, the numbers are 13 and 15.

13² + 15² = 169 + 225 = 394

The sum of the numbers is 13 + 15 = 28.

Explanation

The set {0, ±1, ±2, ±3, ±4, ...} includes all positive, negative integers, and zero.

This set is called the set of integers.

Explanation

Insulin consists of 51 amino acids, divided into two chains: A chain (21 amino acids) and B chain (30 amino acids).

This specific sequence is critical for its function in regulating blood sugar.

Explanation

Multiply the constants: 3 × 4 = 12.

Add the exponents of x: x² × x³ = x⁵, so the product is 12x⁵.

Explanation

Solve the equation: 2x + 3 = 9 → 2x = 6 → x = 3.

The value of x = 3 satisfies the equation.

Explanation

HBV is Highly Contagious:

Transmitted through blood, semen, and other body fluids.

10 times more infectious than HCV and 50–100 times more infectious than HIV.

Can survive outside the body for up to 7 days, increasing transmission risk.

Explanation

Given kinetic energy (K.E) = 1 J and mass (m) = 1 kg:

K.E = ½mv²

1 = ½ * 1 * v²

v² = 2

v = √2 ≈ 1.414

The correct answer is 1.4 m s⁻¹.
