2 corners are both 45 degrees, meaning that they are both the same length.
For this we use the pythagorean theorem, but a bit modified:
a^2 + a^2 = c^2
2a^2 = 256
Solve for a:
a^2 = 128
a = 8 √2
One leg is equal to √128 or 8 √2.
Kinetic engery = -1/2mv^2
Work = Fd
Combine:
-1/2mv^2 - Fd = 0
-1/2mv^2 = (0.30*15000*9.81*cos(6))d = 0
Multiply both sides by 2:
v^2 = 2d(0.30*9.81*cos(6))
Solve for d:
d=v^2 / 2(0.30*9.81*cos96))
v = speed:
d = 35^2 / 2*0.30 * 9.81 * cos(6)
d = 1225 / 5.85376
d = 209.27 meters. Round answer as needed.
Answer:
3,989.2
Step-by-step explanation:
The word tenth goes after the decimal so the number is 2 and sense the number 3 is after and will be rounded down the answer is 3,989.2
Here's the Answer,
=》sin 45º = cos 45º - <em><u>True</u></em>
=》sin 30º = cos 30° - <em><u>false</u></em>
=》cos 10º = sin 80° - <em><u>true</u></em>
=》sin 15° = cos 75° - <em><u>true</u></em>
