Use the Quadratic formula,
x= -b +/- sqrt(b^2-4ac)
-------------------------
2a
x= 4 +/- sqrt(16+12)
----------------------
-6
x = 4+/- sqrt(28)
---------------
-6
x = 4 +/- 2*sqrt(7)
------------------
-6
x= 2(2+/- sqrt(7))
------------------
2(-3)
x= 2+/- sqrt(7)

Answer:
4.969696 hours
Step-by-step explanation:
The distance traveled is shown through the following equations
Distance = velocity * time
This means that
4100=velocity*4
This means that ariplane 1 travles at 1025 km/hr
We can then subtract 200 from this to find that airplane two travels at a speed of 825 km/hr
Now we need to find how long it takes for that plane to travel 4100
So using the same equation
4100=825*time
Divison will tell us that the answer is around 4.9696 hours which is pretty much 5
2x-10=x+15
X-10=15
X=25
Bc the of angle 5 is congruent to angle 7
Answer:
The series 64, 16, 4, 1 is convergent.
Step-by-step explanation:
Let be 
the set of values of the series. A series is convergent if and only if:
(1)
If we know that 
, 
, 
and 
, then the convergence ratio of each pair of consecutive values are, respectively:
, 
, 
Hence, the series 64, 16, 4, 1 is convergent.
My final answer is 7,376 degrees, increase.
