A line segment in geometry is the part of a line which is bounded by two distinct end points.

<h3>What is line segment?</h3>

Your information is incomplete. Therefore, an overview will be given. A line segment simply means a part of a line that has two endpoints.

A line segment contains end points and the points if the line that's between them. A segment is typically named by two endpoints like AB.

Answer:

Step-by-step explanation:

h = -6t^{2} +20t + 4

I will use calculus,  maybe that's not how you're supposed to do this

-12t +20 =0

12t = 20

t = 20 /12

t = 1 \frac{8}{12}

t = 1 \frac{2}{3}

there will be a max at  1.6666666666  seconds

-6*1.6666666666666^{2}  + 20 * 1.6666666666  +4

= 16.666666666666 + 33.333333333333 + 4

= - 16\frac{2}{3} + 33 \frac{1}{3} + 4

= 20\frac{2}{3}  feet max height ( not too high,  for a rocket)

time of flight:

0 = -6t^{2} +20t + 4

use quadratic formula to find t

-20 +- sqrt [ 20^{2} - 4*(-6)*4 ] / 2*(-6)

-20 +- sqrt [400 + 96 ] / -12

-20 +- sqrt [496 ] / -12

-20 +- 22.27105 / -12

try the negative option 1st

-42.27105 / -12

3.522 seconds.     time of flight

when will the rocket be at 12' ? :

12 = -6t^{2} +20t + 4

0 = -6t^{2} +20t -8

use quadratic formula again to find t

-20 +- sqrt [ 20^{2} - 4*(-6)*(-8) ] / 2*(-6)

-20 +- sqrt [ 400 - 192 ] / -12

-20 +- sqrt [208 ] / -12

-20 - 14.4222 / -12

-34.4222 / -12

2.8685 seconds ( on the way down)

and

-20 + 14.4222 / -12

-5.578 / - 12

0.4648  seconds ( on the way up )

x²+x+2x+2=0

x(x+1)+2(x+1)=0

(x+1)(x+2)=0

x=-1,x=-2

so B

a machine can fill 650 bottles in 25 minutes. What is the unit rate at which the machine fills the bottles?
4vir4ik [10]
unit\ rate=\frac{amount\ of\ bottle}{time}\\\\&#10;unit\ rate=\frac{650}{25}=26\frac{bottle}{min}\\\\Unit\ rate\ is\ 26\ bottle\ per\ minute.
