Answer:
t = 2.5 s
Step-by-step explanation:
Suppose you have a water-balloon launcher. The balloon is 3 ft high when it leaves the launcher. Its equation is :
The above equation is a quadratic equation. The general equation is :
Here, a = 16, b = 38.8 and c = 3
The solution of quadratic equation is given by :
So, at t = 2.5 s the balloon is in air.
8 hours. 234 divided by 18 = 13, she makes $13 an hour. So $104 divided by $13 an hour would be 8.
Answer:
total cost is $2444
Step-by-step explanation:
A company’s marginal cost function is where x is the number of units
Marginal cost function is the derivative of cost function
to find the total cost of producing units , take integral of marginal cost function
with intervals 144 to 625
now plug in the values
total cost is $2444
Answer:
x=75
Step-by-step explanation:
∆FSJ~∆DYJ
so the sides are proportional
SJ/YJ=FJ/DJ
(63+42)/42=(x+50)/50
105/42 ×50=x+50
125-50=x
x=75
