I worked really hard on this, if it's wrong, I'm throwing hands, haha

I explained some things too, so zoom in for my ugly handwriting

Rin spends $20 every week on drum lessons.

mihalych1998 [28]

Answer:

A, B, D and F.

Step-by-step explanation:

Rin spends $20 every week on drum lessons.

If:

d = total amount of dollars Rin spends

w = number of weeks

Then: d=20w

w is the independent variable while d is the dependent variable. A change in w will lead to a change in d. Therefore:

(A)The independent variable causes a change in the dependent variable.

(B)The equation is d = 20w.

From the equation: d=20w

When w=1, d=$20

When w=2, d=$40

When w=3, d=$60

When w=4, d=$80

This tallys with the values in Option F.

Therefore:

(D)As the number of weeks increases, the total dollars Rin spends increases.

The correct options are: A, B, D and F.

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)

Show 2 ways 4 people 6-segment chewy fruit worm in each case, how many segments does each person get?

finlep [7]

Question:

Show 2 ways that four people can share a 6-segment chewy fruit worm.

In each case how many segments does each person get ?

Answer:

a. $Each\ Person = 1.5\ segments$

b. $Each\ person = 3\ segments$

Step-by-step explanation:

Given

$Segments = 6$

$People = 4$

Method 1: Simply divide the number of segments by the number of people.

$Each\ Person = \frac{Segments}{People}$

$Each\ Person = \frac{6}{4}$

$Each\ Person = 1.5$

Method 2:

Start by taking LCM of 4 and 6

$4 = 2*2$

$6 = 2 * 3$

$LCM = 2 * 2 * 3$

$LCM = 12$

This means that you divide the chewy fruit into 12 segments. This is done by cutting each segment in half.

Each person gets:

$Each\ person = \frac{Segments}{People}$

$Each\ person = \frac{12}{4}$

$Each\ person = 3$

So, when the fruit is further divided to 12, each person gets 3 segments of the division.
