Answer:
In mathematics, a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a symbol, called the imaginary unit, that satisfies the equation i² = −1. Because no real number satisfies this equation, i was called an imaginary number by René Descartes.
Step-by-step explanation:
Complex Integer
(or Gaussian integer), a number of the form a + bi, where a and b are integers. An example is 4 – 7i. Geometrically, complex integers are represented by the points of the complex plane that have integral coordinates.
Complex integers were introduced by K. Gauss in 1831 in his investigation of the theory of biquadratic residues. The advances made in such areas of number theory as the theory of higher-degree residues and Fermat’s theorem through the use of complex integers helped clarify the role of complex numbers in mathematics. The further development of the theory of complex integers led to the creation of the theory of algebraic integers.
The arithmetic of complex integers is similar to that of integers. The sum, difference, and product of complex integers are complex integers; in other words, the complex integers form a ring.
Guessing it is a rectangle the perimeter is 2*0.625+2.45*2= 6.15
and the area is 0.625*2.45= <span>1.53125..... i think</span>
Answer:
Option (d).
Step-by-step explanation:
Given that,
The area of a Football field is 57,600 sqft
The dimensions of Basketball court is 84ft x 50ft
We need to find what fraction of the football crowd would fit on the court. Taking ratio of the area of basket ball court to the football court as follows :
It is less than a tenth. Hence, the correct option is (d).
Answer:
The answer is 800
Step-by-step explanation:
just divide 600 divided by 75%
easy
and if that doesn't work idk what will... sorry
Odd = 433, 291
