First we have the following equation:
a - b = 0
We clear one of the variables depending on the other:
a = b
Therefore we have to for the following expression:
a + b
We can substitute one of the variables, obtaining:
a + a = 2a
Equivalently:
b + b = 2b
Answer:
a + b = 2a
or
a + b = 2b
Answer:
1 : 2
Step-by-step explanation:
5 cm : 10 cm ← divide each part by 5 cm
= 1 : 2
Answer:
The equation for height is given as
S= -16t2 +V 0 t
Also given
V0 = 128 ft/s
Substituting 192 = -16t2 +128t
Which is simplified as
t2 -8t +12 =0
Which gives t = -2 sec and t= 6 sec ( -2 can be ignored)
Using S = -16 *6*6 +128 *6 = 192 ft
