Answer:
A = 10m^2
Step-by-step explanation:
Divide the figure into 3 smaller figures (a triangle, a rectangle, and a square). Then, solve for the area of each composite figure.
A of triangle = (2 x 2)/2 = 2
A of rectangle = 4 x 1 = 4
A of square = 2 x 2 = 4
A of figure = 2 + 4 + 4 = 10m^2
Another way to solve this is to find the area of the entire figure plus the area of a triangle. This would look like A = 3 x 4 = 12. But, since the extra triangle area is included, we must subtract this from the total area.
A of triangle = (2 x 2)/2 = 2
A of figure = 12 - 2 = 10m^2
Answer:
Minimum -1, maximum 1.
At points (3π/4. -1) and (π/4 , 1)
Step-by-step explanation:
The maximum value for the sine of an angle is 1 and the minimum is -1.
The angle will have values of π/2 and 3π/2 at these points.
As the angle is 2x the angle values will be π/4 and 3π/4.
