Standard form allows you to easily find the y-intercept and determine if the parabola is concave up or down. Also, if it is not factorable, then it is in the correct form to apply the quadratic formula to find the x-intercepts.
By adding all the numbers and dividing by 7 ( the amount of numbers) you know that the answer will be about 166.3
No; just because there is a correlation does not prove causation.
The correlation says that as the amount of rainfall increases, the amount of oranges produced increases as well. It does not state what causes it.
1) either you'll get a negative number
Or
2) You'll get a positive Number..
But I'm guess you'll get a positive number
The answer is letter c. x2-8x+24-[72/(x+3)]. If you do not know how to solve this using the long division method, you can always evaluate the options through the process of elimination first. Since the degree of the other factor is already 1 (x to the power of 1), you know that option d. is not the correct answer because you know that the other factor must be raised to the power of 2. That leaves us with a, b and c. Working backwards and multiplying the given factor (x+3) with the factor in b, gives us x3-5x2+72. So from there, you know that you have to eliminate 72, which can be removed when it is subtracted by itself. Letter c does just that. Try multiplying (x+3) and option c for yourself :).
