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 hi

t by a player. The top of the net is 7.3 feet above the floor. Does the volleyball travel high enough to clear the top of the net?

Answer:

It will travel high enough

Step-by-step explanation:

Find the vertex of the parabola:

x=-b/2a

x=-11/2(-16)

x=-11/-32

x=11/32

Plug x=11/32 into quadratic to get the y-coordinate:

h=-16(11/32)^2+11(11/32)+5.5

h=7.391

Since 7.391>7.3, the volleyball will travel high enough (aka. yes)

Lateral area of triangular prism = (a+b+c)h where a, b and c are the sides of the triangular base, h is the height.

LA= (a+b+c)h=
a=4
b=6
c=?
c=9
h=8

c=√6²+4²=√80 or approximately 9

you should get An Area= (4+6+√80)8

LA= 80+8√80
