Answer:

-(-5) +/- the square root of -5^2 - 4(2)(18) / 2(2)

Step-by-step explanation:

Quadratic formula: -b +/- the square root of b^2 - 4ac / 2a

a = 2, b = -5 c = 18

25 POINTS, I DONT UNDERSTANDDDDDD :C WHAT IS SO MISLEADING ABOUT THIS GRAPH???

Kisachek [45]

Answer:

honestly, the graph look totally fine...

If one ere pressed to find something to complain about it, one could suggest that you do not know if this was the starting price of the stock or the ending price of the stock each day?... One could also argue that to be a bit more meaningful you might want to know the range of prices during each day...

look up what is called a candle stick graph.. each day looks like a candlestick... the top is the highest value each the bottom the lowest, and there is a line in the candle that shows the closing price

A cone has a radius of 1 foot and a height of 2 feet. How many comes of Liquid would it take to fill a cylinder with a diameter

maks197457 [2]

find the volume of the cone:

1/3 pi r squared × h

1/3 pi (1) squared × 2

= 2/3 Pi (feet cubed)

find the volume of the cylinder:

pi r squared × h

(the radius is 1 foot because its half the diameter which is 2 feet)

pi (1) squared × 2

= 2 Pi (feet cubed)

2 Pi is÷ 2/3 Pi

= 3

therefore it will take 3 cones of liquid to fill a cylinder with a diameter of 2 and height of 2
