Explanation

We use "the" before "dollar" because we are referring to the official, specific currency of the United States (a unique entity).

"The dollar" functions like a proper noun in this context (similar to "the euro" or "the yen").

Explanation

2a³ - a³ = (2-1)a³ = 1a³ = a³

This is because when you subtract a³ from 2a³, you are essentially subtracting 1a³ from 2a³, leaving you with 1a³, which simplifies to a³.

Explanation

Nucleic acids (DNA/RNA) are present in:

Nucleus:

• Contains genomic DNA (eukaryotic cells).

Mitochondria:

• Have their own mtDNA (vital for energy production).

Chloroplasts (in plants/algae):

• Contain cpDNA for photosynthesis-related functions.

Explanation

Step 1: Apply the formula (a - b)² = a² - 2ab + b²

(7 - 9)² = (7)² - 2(7)(9) + (9)²

Step 2: Compare with the given options

The correct expansion is (7)² - 2(7)(9) + (9)².

Explanation

Explanation

π (pi) is approximately 3.14159.

The value of Pi (π) is the ratio of the circumference of a circle to its diameter.

Explanation

The formula for the difference of squares is 𝑎² − 𝑏² = (𝑎 − 𝑏)(𝑎 + 𝑏).

Explanation

Given the sequences:

CAT = 1, 2, 3

INK = 4, 5, 6

DOG = 7, 8, 9
