The length of the diagonal is 41
The width, the length and th diagonal of a rectangle form a triangle rectangle and we can apply the theorem of pythagoras as:
Where c is the length of the diagonal, a is the length of the rectangle and b is the width of the rectangle. Replacing values and solve for c, we get:
So, The length of the diagonal is 41.
The answer in interval notation is
Consider the provided inequality.
Subtract 2 from both sides.
The value of function is positive for
The value function is zero at
The value function is negative for
The value function is positive for
Since we want the value of function less than 0, so the required interval which satisfy the condition < 0 is:
The required number line is shown below:
