Find the function with x-intercepts (-2, 0) and (4, 0), which also goes through the point (3, 10).

Option D:  is the function

Explanation: Let the general form of quadratic equation be  The function passes through the intercepts  and  and also passes though the point  Substituting the points ,  and  in the equation , we get,   (1)  (2)     (3) Subtracting (1) and (2), we get,   (4) Subtracting (2) and (3), we get,   (5) Multiplying equation (4) by 5 and equation (5) by 4, to cancel the term b when adding, we get, Thus, the value of a is  Substituting  in equation (4), we get, Thus, the value of b is  Now, substituting the value of a and b in equation (1), we have, Thus, the value of c is  Now, substituting the value of a,b and c in the general formula , we get, Taking out the common term as -2 we get, Factoring , we get, Thus, the function is  

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

answer: 5 17/33 % (to the tenth)

step-by-step explanation:

he guessed: 34.5 pounds

actual weight is 32.7

there for he is off:

34.5 -32.7 = 1.8

32.7 is the 100%

1.8 represents %? of 32.7

therefore:

32.7   - 100%

1.8     -     x%

x= 1.8*100%/32.7% = 18*100%/327%

x=1800%/327%   = (5 165/327)%

to the tenth:

5 17/33 %
