Graphing and equations are two ways of representing functions
Answer:
Step-by-step explanation:
<em>Circumference Formula:</em>
<em>C=2πr</em>
The radius is half of the diameter...
Pi is 
...
Sin Ф=opposite/ hypotenuse
In this case:
sin 25º=9 in /c
c=9 in/ sin 25º
c≈21.3 in.
Answer: sin (25º), in this case can be used to find the lenght of the hypotenuse, and the length of this hypotenuse would be 21.3 in.
Answer:
<em>Correct answer is C. -41</em>
Step-by-step explanation:
Theory:
Number + Additive inverse = 0
Therefore, Addictive inverse of 41 is
Additive inverse + 41 = 0
Additive inverse = -41
Correct answer is C. -41
When we say "closed under addition" in the context of rational numbers, we mean to say that when we add up rational numbers then, the sum is also a rational number.
From the given choices above, the one that should the characteristic of being "closed under addition" is only fourth equation. Both 1/2 and 0.5 are rational numbers. On the other hand, 1 is also a rational number.
