Answer: x² + y² - 2x - 8y + 13 = 0
Step-by-step explanation:
the equation of the circle is in the form (x - a)² + (y - b)² = r²
where (a,b) is the center of the circle and r is the radius
hence the equation is
(x - 1)² + (y - 4)² = 2²
x²-2x+1+y²-8y+16= 4
x²+ y² -2x- 8y + 17 =4
x² + y² - 2x - 8y = -13
x² + y² - 2x - 8y + 13 = 0
Answer: 4 fishes
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a sphere = 4/3 x π x (diameter/2)^3
Replacing with the values given:
V = 4/3 x π x (18/2)^3
v = 4/3 x π x (9)^3 = 3,053.63 in3
Next, we have to divide the volume of the tank by 693 in3 (volume for each fish)
3,053.63/693 =4.40 = 4 fishes
Feel free to ask for more if needed or if you did not understand something.
Answer: x = 4 + y
x= -2 - y/2
Step-by-step explanation:add y to both sides of the equation
Angle Angle Side. The side is given to you and use the interior angle to find one angle, and the the reflexive property to find the other.
Just work this problem out backwards. First write out an equation.
(x+4)•3=30
Now solve :
(x+4)•3=30
3x+12=30
-12 -12
3x=18
/3 /3
x=6
Your answer is 6!
