Answer:
(x + 3)² + (y - 4)² = 32
Step-by-step explanation:
Since we are given the coordinates of the centre and a point on the circle, we can use distance formula to find the radius.
r = √((1 - (-3))² + (8 - 4)²)
r = √(16 + 16)
r = √32
Now, formula for equation of a circle with centre (h, k) is;
(x - h)² + (y - k)² = r²
Our centre is (-3, 4) with r = √32
Thus;
(x - (-3))² + (y - 4)² = (√32)²
(x + 3)² + (y - 4)² = 32
Answer:
B
Step-by-step explanation:
subtract 1/3 from both sides
m< -2 7/12
Answer:
180+45w=900. w= 16
Step-by-step explanation:
we start with 180 already saved. so 900-180 is 720. And 720÷45 is 16. Therefore it will take 16 weeks to save all 900 dollars.
1/20 a gallon I'm pretty sure. 4/5 gallon is equal to 0.8 minus 3/4 or .75 is equal to 0.05 which is 1/20.
17.83 times 1.1
=19.613
17.83+19.613
=37.443
=37.5 dollars
