Answer:
14
Step-by-step explanation:
Use the formula with n=3.
h(3) = h(3-2) +h(3-1)
h(3) = h(1) +h(2)
h(3) = -6 +20 . . . . . substitute the given values
h(3) = 14
3x^-2 can be written
3/x^2 because x^-2 is = 1/x^2
So a square is a special kind of rectangle, it is one where all the sides have the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles. However not every rectangle is a square, to be a square its sides must have the same length.
Are you finding the x-intercept
Answer:
80/111
Step-by-step explanation:
For starters, since it is 3 digits inclusive of 0, from 0 - 9, then there are 1000 possible total plate combination from 000 - 999.
If no number is expected to be repeated in the combination, then there exists 10 numbers(say 0-9) for the first digit, 9 numbers(say 1-9) for the second digit and 8 numbers(1-8) for the third digit.
This means that there will be 10 * 9 * 8 total possible outcomes. Considering that the possible combinations is 999, then the probability is
10 * 9 * 8 = 720/999
And that is simplified to 80/111
