Answer:
D
Step-by-step explanation:
Try to remember this formula.
Where a is the vertical multiplier, b is the horizontal multiplier, c is the x coordinate of the vertex, and d is the y coordinate of the vertex.
Since the vertex on the graph is (2,3), c and d have to be 2 and 3.
Also, there are no vertical/horizontal stretches so the a and b values stay at 1.
The final equation would come out to
Answer:
1/2 or 50% of the population has heard the rumor when it is spreading fastest.
Step-by-step explanation:
We need to take the derivative with respect to y from the r(y) = dy/dt = 2y(1-y) and equal to zero. At this condition we maximize the function and will get the maximum of the rumor spreading.
Therefore we just need to find y:
So 1/2 or 50% of the population has heard the rumor when it is spreading fastest.
I hope it helps you!
Answer:
2.5 gallons per 1 minute
Step-by-step explanation:
A unit rate is a comparison of a value per one. To find the unit rate, write the ratio as 5 gallons per 2 min then divide to find per 1.
2.5 gallons per 1 minute
