<h3>
Answer: sqrt(20)</h3>
=========================================
Explanation:
Count out the spaces, or use subtraction, to find the horizontal side BC is 2 units long. Similarly, you'll find the vertical side AC is 4 units long.
Use the pythagorean theorem to find the length of segment AB.
a^2 + b^2 = c^2
2^2 + 4^2 = c^2
4 + 16 = c^2
20 = c^2
c^2 = 20
c = sqrt(20)
We stop here since it matches with choice B.
-----------------
Optionally, we can simplify like so
sqrt(20) = sqrt(4*5)
sqrt(20) = sqrt(4)*sqrt(5)
sqrt(20) = 2*sqrt(5)
The answer is to your question is 5u1/3
Answer:
x = 20
Step-by-step explanation:
The given angles are vertically opposite and congruent, hence
6x - 10 = 3x + 50 ( subtract 3x from both sides )
3x - 10 = 50 ( add 10 to both sides )
3x = 60 ( divide both sides by 3 )
x = 20
Answer:61 degrees
Step-by-step explanation:
Its congruent angles
For this case we have the following function:
By definition, the domain is given by all the values for which the function is defined.
The given function is no longer defined if the argument of the root is negative. So:
Thus, the domain of the function is given by all the values of x greater than or equal to -3.
Domain: [-3, ∞)
Substituting the values of the domain, we find the range.
The function evaluated in ∞ gives -∞. So the range is given by:
(-∞, 2]
Answer:
Domain: [-3, ∞)
Range: (-∞, 2]
