You see the c next to the 27 plug in 2/3 for it so u would get 10(27(2/3)+8)
Answer:
x+y=12 x-y=2 x=7, y=5
Step-by-step explanation:
you just set the equations up so that the sum is 12 difference is 2. then solve using eliminations, add the 2 equations which gives 2x=14, x=7 then solve for y. Hope this helped!!
Isn’t it 1 / 1 ?or something like that is positive for sure
The practical dominion is from t = 0, when the ball starts motion until the time when the ball hits the ground.
To find the time when the ball hits the ground solve the equation:
h(t) = 0
=> -16t^2 + 68t = 0
Factor: t(-16t + 68) = 0 => t = 0 and -16t + 68 = 0
=> 16t = 68
=> t = 68/16
=> t = 4.25
So, the practical domain is 0 ≤ t ≤ 4.25 s.
Which also may be represented by t ∈ [0, 4.25s]
