Answer:

Additive inverse property is satisfied in the given question

Explanation:

We have been given with two complex numbers  x=1+2i and  y= -1 -2i

we can clearly see that y is additive inverse of x

Since, additive inverse of the complex number is -(a+ib)

Where a and b are real numbers

Here in given numbers a=1 and b=2i

sum of number and its additive inverse is zero.

Answer:  5 cos x

<u>Step-by-step explanation:</u>

y = sin x     is       y = cos x        shifted to the right π/2 units.

y = 5 sin (x + π/2)     is a shift to the left π/2 units (which results in cos x) and    .                                 an amplitude of 5.

--> y = 5 cos x

Calculate the area of the regular pentagon below:
djverab [1.8K]
Assuming the vertex of the triangle shown is the center of the pentagon, and the line segment shown is an altitude of the triangle:

If we join the center of (the circumscribed circle and of) the pentagon to the 5 vertices, 5 isosceles triangles are formed, all congruent to the one shown in the figure. It is clear that these triangles are congruent, so to find the area of the pentagon, we find the area of one of these triangles and multiply by 5.

The base of the triangle is 22.3 in, and the height is 15.4 ins, thus the area of the pentagon is:

5(Area triangle)=5*[(22.3*15.4)/2]=<span>858.55 (square inches).


Answer: </span>858.55 (square inches).
