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
Answer: A Rhombus has 4 congruent sides .
Sean’s power due to the discount will cost $186.10
Answer:
the first one im pretty sure
Step-by-step explanation:
32 divde by 2 = 16 (50%)
32 divde by 10 = 3.2 (10%)
16 - 3.2 = 12.8 (40%)
3.2 times 4 = 12.4 (40%)
You would round the number to the nearest whole because you can't make a . of a shot. Therefore the answer would be that she made 12 shots.
Hope this helps!
