Answer:
-75
Step-by-step explanation:
If he played 6 games at a cost of 25 tokens per game he spent 25*6 tokens.
25*6=150
So, he lost 150 tokens.
Now we need to get how many tokens he won. For this, we just need to sum all the tokens the statement says Manuel won:
0+10+50+0+5+10=75 tokens
So, if we won 75 tokens but lost 150 tokens, the net tokens are:
75 - 150 = -75
So the change is -75, i.e., he lost 75 tokens.

The radius is 33 feet. The height is really a radius. The diameter consists of 2*r
r = diameter / 2
diameter = 66 feet
r = 66 /2 = 33
So you have 2 ways of finding the radius.
Solution
Area of a full circle = pi r^2
Area of a full circle = pi * 33^2
Area of a full circle = 1089 pi
Area of a semicircle = area of a full circle / 2
Area of a semicircle = 1089 * pi /2
Area of a semicircle = 544.5 * pi
Answer
Exact answer in terms of pi is 544.5 * pi
Approximate answer using 3.14 for pi = 3.14*544.5 = 1709.73
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:
Thus the answer is : B (122)
Step-by-step explanation:
The time series was estimated using a time series with 20 time periods.
And the forecasted value for time period t after 20 time periods is 120 + 2t
For time period 21, the value of t is 1.
Hence, the forecasted value for time period 21 is 120 + 2*1 = 122
Thus the answer is : B (122)
