The awnser is 60 because
It is a cube so it has the smae amout of sides
Answer:
- r(0) = <0, 100> . . . . . . . .meters
- r'(0) = <7.071, 7.071> . . . . meters per second
Step-by-step explanation:
<u>Initial Position</u>
The problem statement tells us we're measuring position from the ground at the base of the building where the projectile was launched. The initial horizontal position is presumed to be zero. The initial vertical position is said to be 100 meters from the ground, so (in meters) ...
r(0) = <0, 100>
<u>Initial Velocity</u>
The velocity vector resolves into components in the horizontal direction and the vertical direction. For angle α from the horizontal, the horizontal component of velocity is v₁·cos(α), and the vertical component is v₁·sin(α). For v₁ = 10 m/s and α = π/4, the initial velocity vector (in m/s) is ...
r'(0) = <10·cos(π/4), 10·sin(π/4)>
r'(0) ≈ <7.071, 7.071>
1/13w - 4 is how this can be expressed algebraically.
For this case we observe that we have:
- <em>Dependent variable: Distance
</em>
- <em>Independent variable: time
</em>
We observed that:
- As the time increases, the distance decreases. Therefore, the relationship between the variables is negative.
- The relationship between the variables is non-linear because the behavior does not look like a straight line.
Answer:
B. negative association
C. nonlinear association
