Answer:
(x +3)² +(y -2)² = 185
(x -10)² +(y +2)² = 185
Step-by-step explanation:
One possible equation comes from using one of the points as center. The other possible equation comes from using the other point as center.
The radius can be found from the distance formula:
r² = (x2-x1)² +(y2-y1)² = (10-(-3))² +(2-(-2))² = 169 +16 = 185
The circle formula is ...
(x -h)² +(y -k)² = r² . . . . . . for center (h, k) and radius r
The above equations and the ones shown in the attachment are possibilities.
Answer:
Step-by-step explanation:
Choose the equation that represents the solutions of 0 = 0.25x4 - 8x.
0.25+ (0.25)2 – (4)(1)(-8)
2(1)
X=
-0.25 + (0.25)2 – (4)(1)(-8)
x=
2(1)
8+ (-8)2 – (4)(0.25)(0)
X =
2(0.25)
-8+ (-8)2 – (4)(0.2530
X =
2(0.25)
Answer:
58.9871 rounded to the second decimal place is 58.98.
Step-by-step explanation:
Answer:
x = 1
Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y = 
← k is the constant of variation
To find k use the condition y = 5 when x = 3
k = yx = 5 × 3 = 15, thus
y = 
← equation of variation
When y = 15 then
15 = ( multiply both sides by x )
15x = 15 ( divide both sides by 15 )
x = 1
