b. It is a segment that touches the circle in exactly one point and makes a right angle with the radius.
Nothing really to be explained, it just the definition of the tangent.
It would be the first one because it’s the only one with the same numbers. if all the numbers and xy match then that mean there’s an infinite numbering solutions
Find the difference in gallons and the difference in the weights
46 - 12 = 34 gallons
2399 - 2176 = 223 pounds
so 34 gallons of gas weighs 223 pounds
find weight per pound: 223 pounds / 34 gallons = 6.5588 pounds per gallon
round to 6.6 pounds per gallon
54 gallons - 46 gallons = 8 gallons
8 gallons x 6.6 pounds per gallon = 52.8 pounds, round to 53 pounds
2399 + 53 = 2452 weight of plane with 54 gallons
I would have to say -0.5 then positive 0.25 because the rule seems to be divide by -2.
