Use the Pythagorean theorem to obtain the function D(x) for the length of the diagonal of a double square of width x.

Yuri [45]

Answer:

$D(x)= x\sqrt{2}$

Step-by-step explanation:

Given

$Side = x$

Required

Represent the diagonal as a function

Using Pythagoras theorem, the diagonal is:

$D^2= Side^2 + Side^2$

Substitute x for Side

$D^2= x^2 + x^2$

$D^2= 2x^2$

Take the square root of both sides

$D= \sqrt{2x^2$

Split

$D= \sqrt{2} * \sqrt{x^2$

$D= \sqrt{2} * x$

$D= x\sqrt{2}$

Express as a function.

$D(x)= x\sqrt{2}$

You can plug 1350 or less watts without overloading the circuit.

Step-by-step explanation:

Given,

Circuit overloads at = 2400 watts

Electricity consumed by portable heater = 1050 watts

Let,

x be the additional number of watts you can plug in.

Portable heater + additional watts ≤ Overloading limit

1050 + x ≤ 2400

Subtracting 1050 from both sides

$1050-1050+x\leq 2400-1050\\x\leq 1350$

You can plug 1350 or less watts without overloading the circuit.
