The mean is 77
The median is 90
-82 and 1/2 feet in 2 and 1/4 minutes.
DIVIDE!!
you would get -36.6666667
round it up because its s .6(6)
you get -36.67
hope this helped!
2cos²x + cosx − 1 = 0
(cosx+1)(2cosx-1)=0
so cosx+1=0
or 2cosx-1=0
1) cosx+1=0
cosx=-1
x=π+2πk, k∈Z
2) 2cosx-1=0
2cosx=1
cosx=0.5
x=+-
, k∈Z
find value for the interval [0, 2 pi )

Answer:
Answer:
(2, -16)
Step-by-step explanation: set both (x +2) and (x-6) = 0.
You get the two x-intercepts -2 and 6. Find the midpoint of the two intercepts by -2 + 6 / 2 which gives you x=2. Then plug 2 in for x and solve the original equation. ( 2 - 6)(2+2) = -16. Therefore the vertex is at (2,-16).
117/3 = 39
39 + 39 + 39 = 177
They must be consecutive.
The integers are 37, 39, and 41.
