Answer:

$\sin x = 0$ , $x = \pm \pi\cdot i$ , $\forall i \in \mathbb{N}_{O}$

Step-by-step explanation:

The following trigonometric equation is simplified by using identities:

$\sin x + \sin^{2}x + \cos^{2}x = 1$

$\sin x + 1 = 1$

$\sin x = 0$

Whose solutions are:

$x = \pm \pi\cdot i$ , $\forall i \in \mathbb{N}_{O}$

Answer:

a. 78.6 square feet

b. $7.86

Step-by-step explanation:

a. This simply asks us to calculate the area of the 10 feet diameter pool

Formula for area of circle is ;

pi * r^2 = pi * d^2/4

so Area = 22/7 * 10^2/4 = 78.60 square feet

b. This will be the area of the blanket multiplied by the price per square foot of the blanket

Mathematically, we have that as;

78.60 * 0.1 = $7.86

Step-by-step explanation:

This isnt a cartisean coordinate plane so A is wrong. One of our points is at

$- 3 + i$

Because it coincide with real number 3, and negative imaginary number i.

Conjugates are terms with opposite inverse of terms.

So our conjugates is

$- 3 - i$
