Answer:
When squaring a number it is essentially taking a number and multiplying it by itself. For example, 5^2 is 5×5 (=25).
Answer:
Option B.
Step-by-step explanation:
Integer: A non fractional complete number is known as integer. It can be either positive or negative or zero.
For examples : ...,-3,-2,-1,0,1,2,3,...
It is a clear that the difference between two consecutive integers is 1. It means we have to add 1 in the integer to get the next integer.
We need to express "next integer after the integer n" mathematically. So, we need to add 1 in n.
Required expression
Hence, the next integer after the integer n is n+1.
Therefore, the correct option is B.
Answer:
c
Step-by-step explanation:
By definition we have to:
Sin (x) = C.O / h
Where,
x = angle
C.O = opposite leg
h: hypotenuse.
Substituting values we have:
Sin (C) = AB / 82
We should look for AB. For this, we use the following relationship:
AB ^ 2 + 80 ^ 2 = 82 ^ 2
Clearing AB:
AB = root ((82 ^ 2) - (80 ^ 2))
AB = 18
Substituting we have:
Sin (C) = 18/82
Simplifying:
Sin (C) = 9/41
Answer:
the trigonometric ratio for sin C is:
Sin (C) = 9/41
