Answer:

<h2>4 cuts.</h2>

Step-by-step explanation:

When we have a circle, each cut (supposing the curst are in the exact middle) which give use two haves. So, if we cut one time, we'll have two equal parts, if we cut a second time, we'll have 4 equal parts, a third time, we'll get us 6 equal parts, and if we cut a fourth time, we'll have 8 equal parts.

So, whenever we have this kind of problem dividing circles, we just say that each cut in the exact middle equals two equal haves, so if we have 4 cuts, we just multiply them by 2, 4(2)=8. Therefore, we have 8 equal parts.

I would say the first choose that the vertical axis should use $0.50 intervals instead of $1.
Because this would make it much easier to read and understand and would it would also be more accurate.

What are the points of inflection of k(x)=sinx-(1/4)sin2x

zalisa [80]

Answer:

Option d is correct.

Step-by-step explanation:

The point of inflection of a function y = f(x) at a pointy c is given by f''(c) = 0.

Now, the given function is

$k(x) = \sin x - \frac{1}{4}\sin 2x$

Differentiating with respect to x on both sides we get,

$k'(x) = \cos x - \frac{1}{2} \cos 2x$

Again, differentiating with respect to x on both sides we get,

$k''(x) = - \sin x + \sin 2x = - \sin x + 2 \sin x \cos x$

So, the condition for point of inflection at point c is

k''(c) = 0 = - sin c + 2 sin c cos c

⇒ sin c(2cos c - 1) = 0

⇒ sin c = 0 or $\cos c = \frac{1}{2}$

⇒ c = 0 or $c = \pm \frac{\pi}{3}$

Therefore, option d is correct. (Answer)
