Mathematics

Answer:

Rational

Step-by-step explanation:

<u>Rational numbers:</u>

Rational numbers are such numbers that can be expressed in the form p/q, where the value of q must not be equivalent to 0.

<u>Irrational numbers:</u>

These numbers cannot be expressed in the form p/q, where the value of q must not be equivalent to 0.                                                                                   <u>                                                         </u>

\implies 2.89 = \dfrac{289}{100} \ \ \text{[In} \  \frac{\text{p}}{\text{q}} \ \text{form (\text{q}} \neq 0)]}

Thus, 2.89 is a rational number.

Convert the cartesian equation x2 +y2=16 to a polar equation
VARVARA [1.3K]
X^2+y^2 = 16
can be written as
(x-0)^2+(y-0)^2 = 4^2

We see that the second equation is in the form
(x-h)^2 + (y-k)^2 = r^2

where
(h,k) = (0,0) is the center
r = 4 is the radius

The polar form of the equation is simply r = 4. Why is this? Because the radius is fixed to be 4 no matter what happens with theta. As theta goes from 0 to 360, the points generated all form a circle centered at (0,0) with radius 4. 

Answer: r = 4

We form a committee of 8 people, to be chosen from 15 women and 12 men. (a) How many possible committee can be formed
eimsori [14]

Using the combination formula, it is found that 2,220,075 committees can be formed.

The order in which the people are chosen is not important, hence, the <em>combination formula</em> is used to solve this question.

<h3>Combination formula: </h3>

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by:

C_{n,x} = \frac{n!}{x!(n-x)!}

In this problem, 8 people are chosen from a set of 12 + 15 = 27, hence:

C_{27,8} = \frac{27!}{8!19!} = 2220075

2,220,075 committees can be formed.

To learn more about the combination formula, you can take a look at brainly.com/question/25821700
