Answer:
Yes
Step-by-step explanation:
f(x) = x³ − 9x² + 11x + 21
f(3) = (3)³ − 9(3)² + 11(3) + 21
f(3) = 27 − 81 + 33 + 21
f(3) = 0
Answer
In many ways, math is closely related to science. Mathematics is a scholarly domain, and so the mathematical community works as the scientific community does — mathematicians build on each other's work and behave in ways that push the discipline forward. This progress contributes to scientific breakthroughs.
Step-by-step explanation:
First you have your two numbers: 1.5 and 4.
The question explains that they travel 1.5 miles 4 times each, meaning you multiply the two.
1.5×4=6
So, your answer is 6 miles.
Hope this helps!
First, we determine the speed of the ferry by dividing the distance by the time it took to cover that certain distance.
speed = (1/6) / (3/7)
speed = 7/18
Then, the distance it will travel for an hour is calculated through the procedure below.
distance = (7/18hour) x (1 hour)
distance = 7/18
Therefore, after an hour, the ferry will be able to travel 7/18 of the distance between two ports.
