The beakers shown below have different precisions. label the amount of water in each of the three beakers to the correct number of significant figures. is it possible for each of the three beakers to the correct number of significant figures

The diagram is attached below

Beaker 1: The measurement line is between 32  and 33. There are 5 lines between 32  and 33. Making line is between third line and fourth line(between 6 and 8). So 32.7

Beaker 2: The measurement line is between 30  and 40. We can clearly see the measurement line at 32. So its 32

Beaker 3: The measurement line is between 32.7  and 32.8. We have 10 small lines inbetween them. Measurement line at 4. So its 32.74

(b) the amount of water in each of 3 beakers are not same because we can measure the difference. But they are close to each other.

i not know

step-by-step explanation:

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
