Answer/Step-by-step explanation:
Factor this. GCF=2
2(2cos2x+cos x-1)=0
2(2cos x -1)(cos x+1)=0 Set each factor equal to zero and solve
2cos x -1=0 Add 1 to both sides
2cos x =1 Divide by 2
cos x =1/2
x=π/3
x=5π/3
cos x+1=0 Subtract 1 from both sides
cos x=-1
<u><em>x = π</em></u>

r = radius
Arc length = 2(3.14)r
7.9 cm = r
Plug our values in
Arc length = 2(3.14)(7.9 cm)
Arc length = 49.6 cm

Answer:
1/3 + 3/4 + 4/6 +1/2 =
Step-by-step explanation:
1/6 + 4/6 = 5/6
3/4 + 1/4 = 4/4
5/6 + 4/4 = 9/12
Hello!
First you have to find the volume of the cube
To do this we use the equation a^3
a is a side length
24^3 = 13824
The maximum pyramid can have a maximum side length of 24 and a maximum height of 24 since that is what the cube measurements are
The equation for the volume of a square pyramid is

a is side length
h is height
put in 24 for the values

Square the 24

Divide
576 * 8 = 4608
The answer is B) 4608 cubic centimeters
Hope this helps!
