Perimeter is a continuous line forming the boundary of a closed geometrical figure. perimeter of a pentagon = AB+BC+CD+DE+EA (that is 5 sided figure)
so my plan is easy but effective, calculate all those distances using those coordinates with the aid of distance formular. then you add those distances algebraically .
Answer:
√14 and √42. hope this helps.
Answer:
t = 1.143 s
Step-by-step explanation:
The equation he uses to model the height of the rocket in cm, as function of time is
h(t) = -490 t^2 + 1120t
We can plot this equation using a graphing tool
Please, see attached picture
The rocket reaches his maximum height (640 cm) at
t = 1.143 s
(1/3x+3)=5-x
multiply both sides by three
1x+9=15-3x
add 3x to both sides
4x+9=15
subtract 9 from both sides
4x=3
divide both sides by 4 to isolate x
x=3/4
