a
Step-by-step explanation:
Answer:
x² + y² = 4²
Step-by-step explanation:
The standard equation of a circle centered at the origin and with radius r is
x² + y² = r²
Note that the point (4, 0) is 4 units horizontally and to the right of the center (0, 0). Thus, we know immediately that the radius is 4.
Thus the equation of this circle is x² + y² = 4²
Answer:
False
Step-by-step explanation:
They don't look alike
5 people - pay 135 each
15 people - pay x each
----------------------------------
5 : 15 = x : 135
15 x = 5 * 135
15 x = 675
x = 675 : 15
x = 45
Answer:
B ) 45.00
