The answer to your question is the square root 2 over 2
Answer:
60m/s
Step-by-step explanation:
velocity of the while moving is 30 m/s and it becomes 90 m/s after speeding up at constant rate. so the average velocity of the journey is
[90+30] /2
=60 m/s
Slope (m)= y\x= 9/2 = 4.5
your equation for the line is
y=4.5x+3.5
Answer: first choice 14.142 ft
Explanation:
1) Side length of the square: x
2) Use the Pythagorean theorem to relate the side lenght with the diagonal:
diagonal² = x² + x² = 2x²
3) Clear x:
x² = diagonal² / 2
⇒x = √(diagonal² / 2) = diagonal /√2 = diagonal √2 / 2
4) subsitute diagonal = 5 ft
⇒ x = 5 ft √2 / 2 ≈ 3.536 ft
5) The perimeter of the square is 4 times the side length:
Perimeter = 4 × 3.536 ft = 14.142 ft
