Answer:
v = 39.2 m/s
Step-by-step explanation:
They gave you the equation for velocity during freefall in picture2 as:
v = 9.8t m/s
they ask you what the value of v (velocity) is after t=4 sec.
Just plug in t=4 into the equation.
v = 9.8t
v = 9.8(4)
v = 39.2 m/s
Answer:
67.5
Step-by-step explanation:
- When you calculate the 10% of AED75, it is equal to AED7.5
- Then you subtract AED7.5 from AED75 which is AED67.5
The answers are
M1 = 112°
M2 = 26°
25 is the greatest common factor of 75 and 25. 3 x 25 = 75.
Note that
108° = 90° + 18°
so
sin(108°) = sin(90° + 18°) = sin(90°) cos(18°) + cos(90°) sin(18°) = cos(18°)
Then
sin²(108°) + sin²(18°) = cos²(18°) + sin²(18°) = 1
by the Pythagorean identity.
