Answer:

1. e has the greatest mass.

2. d has the smallest mass.

3. f has the largest volume.

4. a has the smallest volume.

5. b and c have the same volume

6. b and d almost have the same mass, but f and c might have the same. The picture isn't good enough for me to look at the dots close enough to count them.

Step-by-step explanation:

Volume – How much space an object or substance takes up.

Mass – Measurement of the amount of matter in an object or substance.

A circus acrobat is shot out of a cannon. The equation for the acrobat's pathway can be modeled by h= -16t^2+25. How long will i

Alex_Xolod [135]

For this we almost have the following equation:
$h = -16t ^ 2 + 25
$
We must match the equation to zero:
$-16t ^ 2 + 25 = 0
$
From here, we clear the value of t.
We have then:
$16t ^ 2 = 25

t ^ 2 = 25/16$
We discard the negative root because we are looking for time:
$t = \sqrt{ \frac{25}{16} } 

$
$t = \frac{5}{4}$
Answer:
it will take him to reach the ground about:
$t = \frac{5}{4}$ seconds
