Step-by-step explanation:
It's $3.90 for every 30 meters. Or $0.13 for every meter.
Answer:
50 times greater
Step-by-step explanation:
If there are two numbers A and B, where A is greater than B,
If we want to find how many times greater A is to B, we simply divide, so that would be
A/B
Now, we have

and

We simply need to divide to find how much greater is the first number than the second number. Remember dividing numbers in scientific notation:

Thus, we have:

So the first number is 50 times greater than the second
A = -599 if I read the question correctly
Answer:
Some number less than 5
Step-by-step explanation:
If it was more we wouldn't need to subtract to find n.
Answer:
a. 144 ft
b. 5 s
Step-by-step explanation:
h = -16t² + 64t + 80
a. This is a parabola, so the maximum height is at the vertex.
t = -64 / (2 × -16)
t = 2
h = -16(2)² + 64(2) + 80
h = 144
The apple reaches a maximum height of 144 ft.
b. 0 = -16t² + 64t + 80
0 = t² − 4t − 5
0 = (t + 1) (t − 5)
t = -1 or 5
t must be positive, so it takes 5 seconds to reach the ground.
