Answer:
y = 200 + 50x
Step-by-step explanation:
y = cost
x = number of months
The cost is equal to the cost to open the plan plus the monthly fee times the number of months
y = 200 + 50x
The answer is 39.2 m/s
We need the velocity of the rock as it reaches the ground, and it is its final velocity. Since it is the free fall, we also must take into consideration gravitational acceleration (a). Therefore, the formula for the final velocity (v2) is:
v2 = v1 + at
v2 - the final velocity
v1 - the initial velocity
a - gravitational acceleration
t - time
As you can see, the distance in this case is not relevant.
It is known:
v1 = 0 m/s (since it was dropped)
a = 9.8 m/s²
t = 4 s
Therefore, the velocity of the rock as it reaches the ground (v2) is:
v2 = 0 + 9.8 · 4 = 39.2 m/s
Answer:
½ × 1 = ½
1 - ½ = ½
Step-by-step explanation:
½ × 1 (1)
1 - ½ (2)
½ × 1 = ½
1 - ½ = ½
