2 answers:
Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
Number of letters they can use = 4
Number they can use = 3
Total number of letters we have = 26
Total number from 0 to 5 = 6
So, Number of different key codes is given by
Hence, there are 98,706,816 different key codes.
Thus, Option 'D' is correct.

Here we are given the x intercepts at x=3 and x=9
So let us try to make quadratic equation for this using given information.
We have factors in the form (x-a)(x-b)
where a and b are x intercepts given to us.
So rewriting in factored form:
Now let us simplify it:
Let us find the vertex now,
For a quadratic equation of the form:
For x coordinate , we have the formula,
So using this formula for our equation,
So x = 6
Answer: The x-coordinate of the parabola's vertex is 6.
