Answer:

x = -6 x= -3

Step-by-step explanation:

f(x) = x^2+9x+18

Set equal to 0 to find the zeros

0 = x^2+9x+18

Factor, what numbers multiply to 18 and add to 9

6*3 =18

6+3=9

0= (x+6) (x+3)

Using the zero product property

x+6 =0 x+3 =0

x = -6 x= -3

How do you solve x^2-4X-12=0

Pepsi [2]

x² - 4x - 12 = 0

Factor the left side: (x + 2) · (x - 6) = 0

The equation is true if either factor is zero.

If (x + 2) = 0 then x = -2 .

If (x - 6) = 0 then x = 6 .

Safety regulations require that the time between airplane takeoffs (on the same runway) will be at least 3 minutes. When taking

Alenkinab [10]

Answer:

1.96 planes

Step-by-step explanation:

The computation of the number of planes is shown below:

As we know that

System Inventory is

= Flow rate in the system × Throughput time

where,

Flow rate is

= Frequency of taken off

= 16 planes ÷ hour

= 16 ÷ 60 Planes per minute

Throughput time is

= runway waiting time + runway Run time

= 33 seconds + 6 minutes × 60 seconds + 48 seconds

= 441 seconds

= 441 per 60 seconds

Therefore the number of planes is

$= \frac{441}{60} \times \frac{16}{60}$

= 1.96 planes
