Answer:
{2, 3, √13}
Step-by-step explanation:
In a right triangle, the sum of the squares of the two shorter sides equals the square of the third side (Pythagoras).
Let's check each set of sides in turn.
A. {2, 3, √13}
2² + 3² = 4 + 9 = 13
(√13)² = 13
This is a right triangle.
B. {5, 5, 2, √10}
This is a quadrilateral (four sides).
C. {5, 12, 15}
5² + 12² = 25 +144 = 169
15² = 225
This is not a right triangle.
Answer:
smaller value is 1.2
larger value is 6
Step-by-step explanation:

when x=a=0, one has

now, when x=b=2, one has

Therefore, the absolute minumun is

and the absolute maximun is

The approximation to the integral is

hence

Answer:
x = 1
Step-by-step explanation:
Using the rules of exponents
= 
×
⇔ 
Note that 9 = 3² and 27 = 3³ , thus
× 
=
× 
=
× 
= 
=
, then
= 
Since the bases on both sides are equal, equate the exponents
5x - 4 = 1 ( add 4 to both sides )
5x = 5 ( divide both sides by 5 )
x = 1
The answer is 78.
54/9 = 6
6x4 = 24
54+24 =78
