Answer:

Domain = x E R

Step-by-step explanation:

Answer:

-5h - 2

Step-by-step explanation:

3h - 2(1+4h)

Let's first get rid of the ( ) by performing the multiplication:

3h - 2*1 + -2*4h = 3h - 2 - 8h

Now we can subtract 8h from 3h, and that's as simple as it gets:

3h - 2 - 8h = -5h - 2

Answer:

It will take 58 seconds

Step-by-step explanation:

If you have 1 kg of water in the jar, half of it will be 0.5 kg.

To vaporize half of the water (0.500 kg) the energy supply needed is

$2297 kJ/kg*0.5kg=1148.5 kJ$

If the stove is supplying 20 kJ/s, the time its needed is

$\frac{1148.5 kJ}{20\frac{KJ}{s} }=57.425 s$

It will last at least 58 seconds to vaporize half of the water.
