Answer:

Step-by-step explanation:

Circumference of a circle is also referred to as the perimeter bordering the circle.

Thus, it is given as:

C = 2πr

C is circumference

r = half of the diameter of the circle = r

This formula used in finding the circumference of a circle is C = 2πr

Answer:

5901

Step-by-step explanation:

The margin of error is the critical value times the standard error.

ME = CV × SE

For α = 0.05, the critical value is z = 1.96.

The standard error of a proportion is √(pq/n). Given p = 0.04, then q = 1−p = 0.96.

The margin of error is 0.5% or 0.005.

Plugging in:

0.005 = 1.96 √(0.04 × 0.96 / n)

n ≈ 5901

Three more than the product of two and a number x

$2x+3$

You are taking two times a number, which is defined as x. That is equivalent to 2x. Then, you are adding three more to that product.

Determine the zeros of r=2sin5theta

vazorg [7]

Answer:

$\theta=\frac{n\pi}{5}$

Step-by-step explanation:

You have the following function:

$r=2sin5\theta$ (1)

In order to find the zeros of the function you equal to zero the equation (1), and then you solve for θ:

$2sin5\theta=0\\\\sin5\theta=0\\\\5\theta=sin^{-1}(0)=n\pi;\ \ \ \ n=0,1,2,3,..\\\\\theta=\frac{n\pi}{5}$

Then, there are infinite zeros for the function of the equation (1), because n has infinite positive integers values.
