G(x) = k * x^2
108 = k * 6^2
108 = k * 36
Divide both sides by 36
3 = k
g(x) = 3x^2
Answer:
king, queen, jack, ace
Step-by-step explanation:
this depends on what game's rules and scoring you're using, but I'd say the face cards
Answer:
4 mph
Step-by-step explanation:
The speed downstream is (28 mi)/(2 h) = 14 mph.
The speed upstream is (18 mi)/(3 h) = 6 mph.
The speed of the current is half the difference of these:
(14 mph -6 mph)/2 = 4 mph
_____
The current adds to the downstream speed and subtracts from the upstream speed, so the difference of those speeds is twice the current's speed.
Try multiplying each side of the equation by 3, and then
watch out when the answer jumps off the paper at you.
