Answer: the answer is 1/2
Step-by-step explanation:
Answer:
4.18
Step-by-step explanation:
The formule to get the volume of a sphere is 4/3pi*r elevate to 3. So 4/3*3.14 is 4.18 and the radius is 1 so stay equal
0.5x+78.2=287
0.5x=287-78.2
0.5x=208.8
x=208.8÷0.5
=208.8×2
=417.6
Answer:
27607.3619632 meters per hour
Step-by-step explanation:
She was running 7.6 m/s 3600 seconds in a hour
3600x7.6=27607.36
Answer:
For the function
y = cos(1/2 x)
The x-intercept can be calculated by equating the function to zero and solving for x. So,
y = cos(1/2 x) = 0
1/2 x = arc cos 0
1/2 x = 90° +180°n
x =2 (90° +180°n)
x = 180° + 360°n
or converting to radians
x = (180° + 360° n)(π/180°)
x = π + 2π n
where n is any whole number
if n = 0
x = π
Therefore, the x-intercept is π or π+2π n
