<h3>Answer:</h3>
15.56 inches
<h3>Explanation:</h3>
Let L represent the leg length. Then the Pythagorean theorem tells you ...
... 22² = L² + L² . . . . the square of the hypotenuse is the sum of the squares of the other two sides
... 484 = 2L² . . . . . . . simplify
... 242 = L² . . . . . . . . divide by 2; next, take the square root
... √242 = L ≈ 15.56 . . . . inches
_____
<em>Comment on this problem in general</em>
For a hypotenuse of length H, the above equation becomes ...
... H² = L² +L² = 2L²
... H²/2 = L² . . . . . divide by 2
... H/√2 = L . . . . . take the square root (<em>general solution for isosceles right triangles</em>)
For your problem, this is ...
... (22 in)/1.414214 = L = 15.556 in
Answer:
week 1 < week 2
The graph in the attached figure
Step-by-step explanation:
we know that
<em>Week 1</em>
The water level is 1.4 cm
<em>Week 2</em>
The water level is 1 1/2 cm
Convert to decimal number
Remember that
<em>Week 3</em>
The water level is -2.1 cm
Compare the values of week 1 and week 2
1.4 cm is less than 1.5 cm
so
The symbol is <
1.4 < 1.5
week 1 < week 2

Answer:
The sin of 20 degrees is 0.34202, the same as sin of 20 degrees in radians. To obtain 20 degrees in radian multiply 20° by / 180° = 1/9 . Sin 20degrees = sin (1/9 × .
