Answer:
36
Step-by-step explanation:
To do this you have to round the 3. It is the same things as asking to round to the ones place.
To the right of the 3, is a 1. Since this digit is not bigger than a 5, the 3 stays the same.
Your answer is 3
The x-intercept of f(x) = (x + 6)(x - 3)
f(x) = 0 → (x + 6)(x - 3) = 0 → x + 6 =0 or x - 3 =0
x = -6 or x = 3
Therefore the x-intercepts are: (-6; 0) and (3; 0)
Your answer is (-6; 0)
Answer:
heat the air
Step-by-step explanation:
Lightning is just a high-intensity amount of electricity. Picture zapping something with electricity: it doesn't get cold, it gets hot.
That's because when a current is passed through something, it has more energy, so the molecules start to vibrate faster and move around much faster than they were before, which causes friction and a buildup of heat.
