F(x)= 3 (x^2 + 4x +4) - 6
= 3x^2 + 12x +12 -6
= 3x^2 + 12x + 6
Answer: 9 cups of food
Step-by-step explanation:
First find out the amount of food that one puppy eats per day.
Each puppy eats 0.5 cups of food three times a day which means that in total they eat:
= 0.5 * 3
= 1.5 cups of food.
There are 6 puppies in the litter so the total amount of food they eat is:
= 1.5 * 6 puppies
= 9 cups of food
Let r(cos O + i sin O) be a cube root of 125(cos 288 + i sin 288)
then
r^3(cos O + i sin O)^3 = 125(cos 288 + i sin 28)
so r^3 = 125 and cos 3O + i sin 3O = cos 288 + i sin 288
so r = 5 and 3O = 288 + 360p and O = 96 + 120p
so one cube root is 5 (cos 96 + i sin 96)
Im a little rusty at this stuff Its been a long time.
Im not sure of the other 2 roots
sorry cant help you any more
For this case you can solve the problem by applying a simple rule of three in which we have
520 ---> 100%
800 ---> x
Clearing x we have
x = (800/520) * 100 = 154%
the percentage increase in cost was
154-100 = 54%
answer
the percentage increase in cost was 54%
