Answer:

z= 168

Step-by-step explanation:

proportion zinc to copper = 4/17

What is the equation of a circle with the center(-9,-5) and radius equals 9
mezya [45]

Answer:

(x+9)^2+(y+5)^2=81

Step-by-step explanation:

(x-h)^2+(y-k)^2=r^2

(h,k)=center

r=radius

so if you just insert the center (-9,-5) and the r with 9

(x-(-9))^2+(y-(-5))^2=9^2

(x+9)^2+(y+5)^2=81

Hope that helps :)

Polygon ABCD is defined by the points A(-4,2) B(-2, 4), C(1, 3) & D(2,2). Match the coordinates of the points of the transfo
dalvyx [7]

Answer:

D'(-2, 2); C''(3, -1); A'''(4, -2); and B''(4, 2)

Step-by-step explanation:

See attachment for the figure.

<u>For D'</u>, rotating the point (2, 2) 90° counterclockwise. This maps each point (x, y)→(-y, x); it takes (2, 2)→(-2, 2).  

For C'', rotating the point (1, 3) 90° clockwise.  This maps each point (x, y)→(y, -x); it takes (1, 3)→(3, -1).

For A''', rotating the point (-4, 2) 180° clockwise.  This maps every point (x, y)→(-x, -y); it takes (-4, 2)→(4, -2).

For B'', rotating the point (-2, 4) 270° counterclockwise.  This is the similar as rotating the point 90° clockwise.  This maps every point (x, y)→(y, -x); it takes (-2, 4)→(4, 2).
