Answer:
5 seconds
Step-by-step explanation:
When the rocket is on the ground, then h = 0 , that is
- 6t² + 30t = 0 ← factor out - 6t from each term
- 6t(t - 5) = 0
Equate each factor to zero and solve for t
- 6t = 0 ⇒ t = 0 ← when rocket is launched
t - 5 = 0 ⇒ t = 5 ← time when rocket returns to ground
Answer:
P(n) = 2n -200
Step-by-step explanation:
Shara's profit is the difference between her revenue and her cost.
P(n) = R(n) -C(n)
P(n) = 6n -(4n+200)
P(n) = 2n -200
Answer:
y = 5x + 3
Step-by-step explanation:
Slope = (13 - 8)/(2-1) = 5
Equation:
y - 8 = 5(x - 1)
y - 8 = 5x - 5
y = 5x - 5 + 8
y = 5x + 3 <-----------the slope-intercept form
