How to determine instantaneous rate of change with pi

Dafna1 [17]

The instantaneous rate of change of the function is 5/π

<h3>How to determine the instantaneous rate of change?</h3>

The function is given as

$f(x) =\cos(x - \pi) + 4$

Where

$x = \pi$

Calculate f(π) as follows

$f(\pi) =\cos(\pi - \pi) + 4$

This gives

$f(\pi) =\cos(0) + 4$

Evaluate the expression

$f(\pi) =5$

The instantaneous rate of change is then calculated as;

$f'(x) = \frac{f(\pi)}{\pi}$

This gives

$f'(x) = \frac{5}{\pi}$

Hence, the instantaneous rate of change of the function is 5/π

The spinner is divided into eight equal sections marked with eight different colors what situation could be represented by the s

meriva

I believe the answer you looking for is Probability.

This means that if someone spinned that wheel, they have a probability of getting the color they need.

For instance,
Let's say this wheel had the colors red, orange, yellow, green, blue, indigo, purple, and pink.
If I wanted the color red on the spinner, I have a 1/8 chance to spin the color red. I have a 7/8 chance of NOT spinning red. However, let's say the wheel had 4 colors that were pink and 4 colors that were blue. If I wanted to spin the color pink, I would have a 4/8 chance OF spinning it and a 4/8 chance of NOT spinning it. 4/8 is also equivilant to 1/2.

I hope this helps you understand!!
Please mark brainliest!!
Thanks!!

Find [5(cos 330 degrees + I sin 330 degrees)]^3

earnstyle [38]

Given a complex number in the form:
$z= \rho [\cos \theta + i \sin \theta]$
The nth-power of this number, $z^n$ , can be calculated as follows:

- the modulus of $z^n$ is equal to the nth-power of the modulus of z, while the angle of $z^n$ is equal to n multiplied the angle of z, so:
$z^n = \rho^n [\cos n\theta + i \sin n\theta ]$
In our case, n=3, so $z^3$ is equal to
$z^3 = \rho^3 [\cos 3 \theta + i \sin 3 \theta ] = (5^3) [\cos (3 \cdot 330^{\circ}) + i \sin (3 \cdot 330^{\circ}) ]$ (1)
And since
$3 \cdot 330^{\circ} = 990^{\circ} = 2\pi +270^{\circ}$
and both sine and cosine are periodic in $2 \pi$ , (1) becomes
$z^3 = 125 [\cos 270^{\circ} + i \sin 270^{\circ} ]$
