Explanation

tan 45° = 1 in trigonometry.

Explanation

Explanation

To evaluate the expression, follow the order of operations (PEMDAS):

1. Evaluate the innermost parentheses:

1.4 - 0.5 = 0.9

So, the expression becomes:

1.5 + (0.7 + 0.9)

2. Evaluate the next set of parentheses:

0.7 + 0.9 = 1.6

Now, the expression becomes:

1.5 + 1.6

3. Finally, add the numbers:

1.5 + 1.6 = 3.1

Explanation

To divide the expression, follow the quotient rule:

9y⁴ ÷ 3y² = (9/3) × (y⁴/y²)

Simplify:

3 × y²

So, the correct answer is:

3y²

Explanation

When a quadratic polynomial (degree 2) is divided by a linear factor (degree 1), the quotient will have a degree one less than the original polynomial.

That means the result will be a linear polynomial (degree 1).

10 × 4 = 40

40 × 4 = 160

160 × 4 = 640

640 × 4 = 2560
