Answer:
10 cm
Step-by-step explanation:
multiply first 4×2 which is Base. then multiply by 1 1/4 which is 10
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.
Answer:
The best and most correct answer among the choices provided by your question is the third choice or letter C. The total number of hours is 17.
For h>7
C=210+20(h-7)
C=210+20h-140
C=20h+70, h>7
410=20h+70
20h=340
h=17 hours

Answer:
Step-by-step explanation:
So we have:
And we want to solve for π.
First, divide both sides by h:
Now, divide both sides again by r²:
And this is our answer :)
In order for the data set to represent a function, there can be no duplicates of the first value.
A. 1 is used as the first value more than once <em> it is NOT a function</em>
B. 3 is used as the first value more than once <em> it is NOT a function</em>
C. no first number is used more than once <em>it IS a function</em>
D. 3 is used as the first value more than once <em> it is NOT a function</em>
Answer: C
