Here we're applying a basic physics rule for vertical motion where the only pull on the object is gravity.
This rule has the form
h(t) = h + v t + (1/2)a*t^2
o o
To adapt this rule to this particular question replace h with 0, as the
o
upward path of the object begins at 0 ft. Replace v with +15 ft/sec.
o
Replace "a" with (-32.2 ft/(sec^2); this is the acceleration due to gravity.
Then we have the following, with the label F(t):
F(t) = 0 + (15 ft/sec)t + (1/2)(-32.2 ft)/(sec^2), or
F(t) = 15t - 16.1t^2. Thus, Choice D is correct.
Please note: To avoid confusion, please use " ^ " to denote exponentiation:
F(t) = -16t^2 + 15t
Call Dawn's wage x, we will have Vesna's wage = x + 17 and Chris' wage = 4x(x + 17). So we have the equation:
Therefore, Chris's wage:
Answer:
x=5
Step-by-step explanation:
Pull out like factors :
3x - 15 = 3 • (x - 5)
Equation at the end of step 1 :
Step 2 :
Equations which are never true :
2.1 Solve : 3 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
2.2 Solve : x-5 = 0
Add 5 to both sides of the equation :
x = 5
One solution was found :
x = 5
1200 shirts every 6 hours is the same as 200 shirts every hour.
then you multiply 200 by 9(total number of hours in work day) to get 1800 (total number of shirt made in work day)
You're trying to achievce 12,600 shirts so just divide by 1800
12600/1800 = 7
it would take 7 days to make all those shirts
