The perimeter is 11 inches.

One side is 2 inches shorter, so two sides would be 4 inches shorter total.

Subtract 4 from 11 to get 7 inches.

Divide 7 by 4 ( the number of sides):

7 / 4 = 1.75

The shorter side is 1.75 inches.

Now add 2 inches to that for the longer side:

1.75 + 2 = 3.75 inches.

Check: 3.75 + 3.75 + 1.75 + 1.75 = 11

The longer side is 3.75 inches.

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
