You can convert 1000 to hex and see how many digits that requires:
So every integer below 1000 needs up to 3 digits.
Alternatively, we know that
, and that
requires
digits in its hex representation (e.g.
). Taking the logarithm, we get
, and adding 1 gives the number of digits needed to represent
. Similarly,
Answer:
bottom box
Step-by-step explanation:
To best show this information, the scale for the <em>T</em>-axis of his graph should go from 0 to at <em>least </em>11, and the <em>h</em>-axis of his graph should go from 0 to at <em>least </em>40.
Apologies for any incorrect answer, hope this helped.
1 meter = 1000 mm
so then 5 meters is just 5 * 1000 = 5000 mm.
It crosses the x axis when y = 0.
so we need to solve x^2 - x - 2 = 0.
This is done as follows:
x^2-x-2=0
(x-2)(x+1) = 0
Therefore x = 2 or x = -1.
So the two coordinates are (2,0) and (-1,0) the answer is A
