The equation of this parabola will have the form f(x) = a(x+5)(x-4), which works out to f(x) = a(x^2 + x - 20). Since the parabola passes thru (3,40),
40 = a(3^2 + 3 - 20), or 40 = a(-8), so a = -5.
Thus, the equation of this parabola is y = -5(x^2 + x - 20).

Answer:
A
Step-by-step explanation:
The numbers are ordered, such that the first number (the largest one) is:
(5 + 1/2)
And the last number (the smaller one) is (5 + 1/3). Only by knowing this, we will see that the correct options are A and C.
We want to see which of the following numbers is not on the list:
A) √25
B) 5.45
C) 5 12
D) 5.34
One of these numbers can only be in the list if it is larger than (5 + 1/3) and smaller than (5 + 1/2).
To see this easier, let´s rewrite both of these:
5 + 1/2 = 5 + 0.5 = 5.5
5 + 1/3 = 5 + 0.33 = 5.33
Then if a number is smaller than 5.33, the number can't be in the list.
Here we can see two numbers that are smaller than 5.33
These are:
Option A) √25 = 5 < 5.33
Option C) 5.12 < 5.33
And there is no number larger than 5.5
Concluding, the numbers that are not in Demichael's list are:
√25 and 5.12

Answer:
The coordinates of the midpoint are (5/2 , 2) ....
Step-by-step explanation:
The midpoint is the average values of the endpoint coordinates
We have to find the midpoint of (x1,y1) (x2,y2) = (3, -5) , (2, 9)
We have:
(3, -5) , (2, 9)
To find the coordinates of the mid point we will apply:
M(x1+x2/2 , y1+y2/2)
Now substitute the values:
M(3+2/2, -5+9/2)
M(5/2 , 4/2)
M(5/2 , 2)
Thus the coordinates of the midpoint are (5/2 , 2) ....
