Answer:
0
Step-by-step explanation:
slope m = (y₂ - y₁) / (x₂ - x₁)
= (5 - 5) / (4 - 9)
= 0 / -5
= 0

Step-by-step explanation:
If his best time is x, and the best time is smaller, then (1+1/3)*x=his second best time. If x+4=his second best time (since his second best time is 4 seconds slower), then (1+1/3)*x=x+4. Multiplying it out, we get (3/3+1/3)*x=x+4
=4x/3=x+4. Subtracting x from both sides, we get 4x/3-3x/3=x/3=4. Multiplying both sides by 3, we get x=12=his best time
Answer:
A
Step-by-step explanation:
Answer:
V = 4/3 (3.14) r^3
V = 4/3 (3.14) (5^3 - (4)^3)
V = 4/3 (3.14) (125 - 64)
V = 255.4 cm cubed
