A natural number is a positive integer, example, 1,2,5,299 etc.
A rational number is a number that can be expressed as a fraction of integers, such as 245/127, 1/2, 5/1,8/1,...
Since a natural number can be expressed as a fraction of integers, so
a natural number IS a rational number.

Using the factor theorem, the equation for q is:

The <em>Factor Theorem</em> states that a polynomial function with roots
is given by:
In which a is the leading coefficient.
In this problem:
- Passes through the origin, so x = 0 is a zero, that is
. - x = i is a zero, and thus, it's conjugate also is, that is, x = -i, hence

- x = 7 - i is a zero, and thus, it's conjugate also is, that is, x = 7 + i, hence

Then, the equation is:


Considering that 



q(-1) = -520 means that when
, and this is used to find a.





Hence, the equation is:

Answer:
-3
Step-by-step explanation:
the answer would be -3 because it just makes sense I guess
In triangle ABC, two angles angle A and C are already given
Angle A =33.7
Angle C = 26.4
We know that the sum of angles in a triangle is 180 degree
Angle A + B + C = 180
33.7 + angle B + 26.4 = 180
60.1 + angle B = 180
Angle B = 119.9 degrees
Now we use sin angle formula to find b. Given a=24



b = 37.4979
Round answer to two decimal places
b = 37.50
