Answer: C (4,5)
Explanation:
From point N to point P the slope is 2/2 where u move up by 2 and to right by 2
Thus point (4,5) will be crossed by the line
Answer:
4) Increase from 0 to 1
Step-by-step explanation:
We have to analyze the value of cos(Ф) from -π/2 to 0. This can be done if we simplify evaluate the value of cos(Ф) at these two extreme.
This shows that value of cos(Ф) is 0 at -π/2 or -90 degrees and increased to 0 at 0 degrees.
This answer can be validated if you visualize the graph of cos function. Cos function has a peak at 0 degrees, i.e. a value equal to 1. On right and left side of 0 degrees, the curve starts falling down and eventually touches the horizontal axis at 90 degrees and -90 degrees. This is shown in the graph attached below:
Maximizing the Area of a Rectangle with Fixed Perimeter. Drag the locators to vary the width of the rectangle and see the effect on its area. For a rectangle with a perimeterof 40, the height is always 20 minus the width. This allows you to reduce the formula for the area, , to .
