Answer:
The volleyball travel high enough to clear the top of the net.
Step-by-step explanation:
The height of a volleyball, h, in feet, is given by h = −16t² + 11t + 5.5, where t is the number of seconds after it has been hit by a player.
Now, for h = 7.3 feet, we can write
7.3 = - 16t² + 11t + 5.5
⇒ 16t² - 11y + 1.8 = 0
Using the quadratic formula we get,
⇒
⇒ t = 0.27 or t = 0.42
Therefore, for the two real positive values of t the volleyball travel high enough to clear the top of the net. (Answer)

Answer:
correct
Step-by-step explanation:
he is correct because the transformation is a translation and under the translation the image and preimage are congruent.
the measure of the sides are preserved, and the peasure of the angles are preserved so if all the corsponding sides and angles are congruent the hexagons are congruent too
Perimeter is the distance around the shape.
Formula for rectangle P = 2l + 2w
They are two triangles faces that are (6x2)/2 = 6 and the other one is 6 to
so that's 12
the top side is 4 x 2 = 8
back side is 3 x 2 = 6
the bottom side is 2 x 6 = 12
so its 12 + 8 + 6 + 12 = 36 inches squared surface area
