Please read the following picture below and use 3.142 instead of <img src="https://tex.z-dn.net/?f=%5Cpi" id="TexFormula1" title

Check the picture below.

now, let's notice the larger "yellow" semicircle, it has a gap, the gap on the right is of a semicircle with a diameter of 10, BUT it also has a descender on the left, a part that's hanging out, that part is also a semicircle.

so if we use the descending semicircle to fill up the gap on the right, we'll end up with a filled up larger semicircle, whose diameter is 20, and whose radius is 10 cm.

$\bf \textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=10 \end{cases}\implies A=\pi 10^2\implies A=100\pi \\\\\\ \stackrel{\textit{half of that for a semicircle}}{A=\cfrac{100\pi }{2}}\implies A=50\pi \implies \stackrel{\pi =3.142}{A=157.1}$

For the coordinates of P and M (the midpoint) are given. Find the coordinates for Q.

zhenek [66]

Given an endpoint of a segment and a midpoint, the other endpoint can be obtained by manipulation of the midpoint formula. The said formula is shown below:

Let: (a,b) = coordinates of point 1 ; (c,d) = coordinates of point 2; (e,f) = coordinates of the midpoint

Midpoint = ( (a+c)/2 , (b + d)/2 )

From the formula: (a+c)/2 = e ; (b + d)/2 = f

Since we are already given an endpoint and the midpoint, we can solve for the other endpoint using the obtained equations. This is shown below:

(a+c<span>)/2 = e
</span>(3 + c)/2 = 0
c = -3

(b + d<span>)/2 = f
</span>(11 + d)/2 = 0
d = -11

Therefore, the coordinates of the other point is Q(-3,-11)

ladessa [460]

Answer:

(7-5i)( 2+3i)

=7(2)+ 7(3i)-5i(2) -(5i)(3i)

= 14 +21i -10i +15

= 29 +11i
