Find a unit vector parallel to the vector `-3hati+4hatj`.

Explanation

To find a unit vector parallel to the vector \(-3\hat{i} + 4\hat{j}\), we can follow these steps:

### Step 1: Define the vector
Let \(\mathbf{a} = -3\hat{i} + 4\hat{j}\).

### Step 2: Calculate the magnitude of the vector
The magnitude (or length) of vector \(\mathbf{a}\) is given by the formula:
\[
