Answer:

You have 8 choices for the third digit (digits 0 - 9 excluding the numbers you chose for the first and second digit). So by the multiplication principle (MP), there are 9*9*8 ways to do this. So there are 648 numbers that are 3 digit numbers and have no repeated digits.

Create the quadratic function that contains the points (0,2), (1,0), and (3,10). Show all of your work for full credit.
Marina86 [1]

Answer:

y=7/3x²-13/3x+2

Step-by-step explanation:

<u>Determine the value of c:</u>

y=ax²+bx+c

2=a(0)²+b(0)+c

2=c

<u>Substitute (1,0) into the quadratic and create an equation with a and b:</u>

y=ax²+bx+2

0=a(1)²+b(1)+2

0=a+b+2

-2=a+b

<u>Do the same with (3,10) to get a second equation:</u>

y=ax²+bx+2

10=a(3)²+b(3)+2

10=9a+3b+2

8=9a+3b

<u>Set the two equations equal to each other and solve for a and b:</u>

-2=a+b

8=9a+3b

<u>Multiply first equation by 3 and eliminate b to find a:</u>

 -6=3a+3b

- (8=9a+3b)

_______

-14=-6a

14/6=a

7/3=a

<u>Substitute 7/3=a into the first equation:</u>

-2=7/3+b

-2-(7/3)=b

-13/3=b

<u>Final equation:</u>

y=7/3x²-13/3x+2
