Answer:
7
Step-by-step explanation:
There is a point of inflection at each point where the graph crosses the line y=2. There are 7 points of inflection shown.
__
A point of inflection is where the graph changes from being concave downward to concave upward, or vice versa. For a sine function, that is everywhere the function crosses its midline.
The answer is NO,because if you put 3 CDs or less in each shelf you only can put 15 (3*5=15), the same reason for both questions.
Multiply the speed of the train by how many hours it travels:
22.5 miles per hour x 2.5 hours = 56.25 mile.
The train is 60 miles from it's destination, so now you want to subtract the miles it will travel in 2.5 hours from the total distance:
60 miles - 56.25 miles = 3.75 miles away from its destination.
The property that is preserved under dilation is the similarity. The answer is letter A. Dilation of a figure starts from the very center of it and then continually increased or decreased depending on the desired size. It is similarity that is under dilation because no matter how big or small the size of the figure is, it has a similar feature from the original one.
