1. F=ma
F = (2500)(4.8)
F = 12,000 N
2. a = F/m
a = 250/40
a = 6.25m/s^2
3. m = F/a
m = 50/1.2
m ≈ 41.67 kg
4. Speed = Distance covered/time
= 2300/4.25*
≈ 541.18 mph
*15 minutes is 0.25 hours (15 times 4 = 60)

5. same formula above
250/45 ≈ 5.56 km/min

remember these formula triangles for the future :)

How does the graph of f (x) = |x| compare with the graph of g (x) = -1/2 |x|?
777dan777 [17]

Answer:

The graph of f(x) = |x| is a v-shape and doesn't cross over the x-axis.

The graph of g(x) = -1/2|x| is still a v-shape, but it's upside-down and a bit wider. This is because of the coefficient in front of the |x|.  The negative sign flips the graph of |x| and the 1/2 makes the slope smaller, therefore the graph is less steep.

I've attached a picture of the two lines below!

The volume of a large tank is 210 ft3. It is 5 3/5
IRISSAK [1]

Answer:

20 5/6 ft

Step-by-step explanation:

5 3/5 = 28/5

1 4/5 = 9/5

V = l * w * h

210 = l * 28/5 * 9/5

210 = l * 252/25

multiply both sides by 25/252

5250/25 = l

Reduce

20 5/6 = l

20 5/6 ft
