The area of a rectangle is 735 in squared. The ratio of the length to the width is 5 : 3. Find the length and the width.

Answers

Answer: Length = 35

Width = 21

Step-by-step explanation:

From the question, we are informed that the area of a rectangle is 735 in squared and that the ratio of the length to the width is 5 : 3.

To find the length and the width of the rectangle goes thus. We should note that the area of a rectangle is the length multiplied by the width.

Therefore, 5x × 3x = 735

15x² = 735

x² = 735/15

x² = 49

x = ✓49

x = 7

Recall that length = 5x = 5 × 7 = 35

Width = 3x = 3 × 7 = 21

The vertex of the absolute function g(x) = |x|- 8 lies at (0,-8).

What is an absolute function?

The absolute value or modulus of a real number x, denoted by |x|, is its non-negative value regardless of its sign.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the absolute function is g(x) = |x| - 8. The vertex will be calculated by plotting the function on the graph.

From the graph, the vertex of the absolute function lies at the point ( 0,-8). The graph is attached with the answer below.
