Answer:
(x - 6)(x + 4)(x - 2)
Step-by-step explanation:
since x = 6 is a root then (x - 6) is a factor
x³ - 4x² - 20x + 48 ÷ (x - 6)
= (x - 6)(x² + 2x - 8)
= (x - 6)(x + 4)(x - 2) ← factors of f(x)
At T=4, y = 54. Hope I was able to help
The answer is d
when you plot all the points on a graph, it makes a straight diagonal line, making it a positive liner function. none of the inputs or outputs are repeated either.
By simplifying the ratio. Usually you have to make the bottom 1.
Answer:
60mph
Step-by-step explanation:
Speed is the rate of change in distance. Mathematically,
Speed = Distance/Time
Difference in distance between A and B = 285-105miles = 180miles
Total time taken between 2pm and 5pm is 3hours
Speed = 180miles/3hours
Speed = 60miles/hour
Therefore the train speed between the checkpoints is 60miles/hour
