Answer:
The equation of the parabola is
, whose real vertex is
, not
.
Step-by-step explanation:
A parabola is a second order polynomial. By Fundamental Theorem of Algebra we know that a second order polynomial can be formed when three distinct points are known. From statement we have the following information:
,
, 
From definition of second order polynomial and the three points described above, we have the following system of linear equations:
(1)
(2)
(3)
The solution of this system is:
,
,
. Hence, the equation of the parabola is
. Lastly, we must check if
belongs to the function. If we know that
, then the value of
is:


does not belong to the function, the real point is
.
The answer is 40 EXPLANATION: 6% of 30 is 20%. 20% of 200 is 40
Answer:
4 muffins
Step-by-step explanation:
just divide 8 by 2 or see how many times 2 can go into 8.
7 because 7•3=21 and if he has as twice much as you 7•2=14 & 14+7=21 books together
If she has half a pound of sunflower seeds and wants to split it into eight equal packets, each packet would be 1/16 of a pound. 1/16 of a pound is 1 ounce.
Therefore, each packet of seeds would weigh 1 ounce (1 oz.)
