Answer:

(x - 5i)(x + 5i)

Step-by-step explanation:

Write this as x^2 + 25. Solving for x^2, we get x^2 = -25.

Recall that the square root of a negative number is an imaginary one. √(-25) equals ±5i (there are two roots, one positive and one negative).

Then x = ±5i.

In factored form, the given expression is (x - 5i)(x + 5i).

bazaltina [42]

Answer: 4 V

Step-by-step explanation:

The formula for electrical power $P$ is:

$P=\frac{V^{2}}{R}$

Where:

$P=0.5 W$ is the water heater electrical power

$V$ is he water heater voltage

$R=32 \Omega$ is the electrical resistance

Isolating $V$ :

$V=\sqrt{PR}$

$V=\sqrt{(0.5 W)(32 \Omega)}$

Hence:

$V=4 V$
