Hello :
<span>note :
an equation of the
circle Center at the w(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : </span><span>x²+y²-16x+6y+53=0
(</span>x²-16x) +( y²+6y ) +53 = 0
(x² -2(8)x +8² - 8²) +(y² +2(3)x -3²+3² ) +53=0
(x² -2(8)x +8²) - 8² +(y² +2(3)x +3²)-3² +53=0
(x-8)² +( y+3)² = 20
the center is : w(8,-3) and ridus : r = <span>√20</span>
Answer:
128 square inches
Step-by-step explanation:
diagonal of the shaded region = length of the outer square = 16 in
Area of the shaded region =1/2*d²
Answer:
1.02 as a decimal
1 and 1/50 as a fraction
Step-by-step explanation:
I can't really make a number line here but
between -20 and -4, just make a number line and count and you should reach -12. Because they are |8| away from -12.
If point A is -8, them between -8 and 0 is -4.
