(x+2)² +(y+10)² =4
(x-h)² +(y-k)² =r²
(x-(-2))² +(y-(-10))² =2²
h=-2,
k=-10
Center is (-2, -10).
Radius r=2.
Answer C. Center is (-2, -10), r=2.
Answer: 75.108
Step-by-step explanation:
1 gallon is 8.3454 lb so multiply by 9 to get the answer
8.345*9= 75.105 lbs
So there are 75 lbs in 9 gallons
To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
