Use a graphing calculator to approximate the vertex of the graph of the parabola defined by the following
vivado [14]

Answer:  (-0.4, 6.8)

The graph is attached

Step-by-step explanation:

We can find the axis of symmetry using the formula x = -b/2a

x = - -4/2(-5)

x = 4/-10

x = 0.04

Substitute for x and calculate y

y = \left(0.4^{2}\right)\left(-5\right)-4\left(-0.4\right)\ +6

y = 6.8

Which steps could be used to solve this story problem? The librarian was organizing some books on some shelves. She had 200 fict
VashaNatasha [74]
Hi there! The answer is A. Add together 200 and 100. Then divide the sum by 6.

In this problem we want to know how many books there are on 1 shelf. Therefore we must first now the total amount of books and so we add up 200 and 100 (which makes a total of 300 books)

Finally we divide this total amount of books by the amount of shelfs (300 / 6), and then we've found the answer to our question. Hence, the answer is A.
