The club currently have 25 members

Yolanda's club requires that 80% of the members be present for any vote. If at least 20 members must be present to have a vote, it means that 80% of the members in Yolanda's club is 20 members.

In order to determine the number of members in the club, use this formula:  

Number of members in the club = least number of members that have to be present to vote / percentage of members that must be present to vote

least number of members that have to be present to vote = 20

percentage of people that must be present to vote = 80%

20 / 0.8 = 25 members

Answer:

The answer to your question is letter B.

Step-by-step explanation:

Data

Center = (-10, 6)

radius = 8

Process

1.- To find the answer to your question just substitute the values in the standard form of the circle.

Equation

                    (x - h)² + (y - k)² = r²

h = -10

k = 6

r = 8

Substitution

                   (x + 10)² + (y - 6)² = 8²

Simplification

                   (x + 10)² + (y - 6)² = 64

Find the argument of the complex number z=1+iv3
elena-14-01-66 [18.8K]

Given:

The complex number is:

z=1+i\sqrt{3}

To find:

The argument of the given complex number.

Solution:

If a complex number is z=x+iy, then the argument of the complex number is:

\theta=\tan^{-1}\dfrac{y}{x}

We have,

z=1+i\sqrt{3}

Here, x=1 and y=\sqrt{3}. So, the argument of the given complex number is:

\theta =\tan^{-1}\dfrac{\sqrt{3}}{1}

\theta =\tan^{-1}\sqrt{3}

\theta =\tan^{-1}\left(\tan \dfrac{\pi}{3}\right)

\theta =\dfrac{\pi}{3}

Therefore, the argument of the given complex number is \theta =\dfrac{\pi}{3}.

Radius = 1.25cm
81cm3 / 20 = 4.05 cm3 per cone
V cone = πr^2 (h/3)
So then 4.05 = π(1.25)^2 (h/3)
Then h/3 = .825 and then

h = 2.475 cm
