Answer:
3000
Step-by-step explanation:
1000 + 2000 = 3000
30 * 0.05 + 1 = X
1.5 + 1 = X
2.5 = X
The light remains yellow for 2.5 seconds on a street with a speed limit of 30.
For this case we must resolve the following inequality:
Applying distributive property on the left side of inequality we have:
Subtracting 5 from both sides of the inequality:
Subtracting 4x from both sides of the inequality:
Thus, the result is
Answer:
Answer: The maximum height the football reaches = 51.89 feet.
Step-by-step explanation:
Given: The equation gives the height h, in feet, of a football as a function of time t, in seconds, after it is kicked.
Differentiate the given equation, we get
(i)
Put
Differentiate (i) w.r.t. t, we get
< 0 i.e. h is maximum at t= 1.65625
The value of h at t= 1.65625 will be
Hence, the maximum height the football reaches = 51.89 feet.
