Suppose the corn size is 10 inches now. SO, according to the problem it grows 3 inches per week. Hence corn will be
10+3=13 in the next week.
13+3=6 in the second week
16+3=19 in the third week and so on.
So, the changes in the plant size is always equal.
Hence, it's an example of linear function.
All you needed to do was plug in 5 into C
It would be $947.50 because you would multiply $189.50 by 0.05.
A) 24
All side lengths of a square are equal so you take the square root of 576 to get two 24. If you try it back: 24*24 (w*h) to get 576.
Answer:
Step-by-step explanation:
A 2nd order polynomial such as this one will have 2 roots; a 3rd order polynomial 3 roots, and so on.
The quadratic formula is one of the faster ways (in this situation, at least) in which to find the roots. From 2x^2 + 4x + 7 we get a = 2, b = 4 and c = 7.
Then the discriminant is b^2 - 4ac, or, here, 4^2 - 4(2)(7), or -40. Because the discriminant is negative, we know that the roots will be complex and unequal.
Using the quadratic formula:
-4 ±√[-40] -4 ± 2i√10
x = ------------------ = ------------------
4 4
-2 ± i√10
Thus, the roots are x = ------------------
