Answer:
the answer is smallest to biggest
Step-by-step explanation:
2x+3y=60 solve for x...
x=(60-3y)/2
p=xy^3, using x from above:
p=y^3(60-3y)/2
p=(60y^3-3y^4)/2
dp/dy=(180y^2-12y^3)/2
dp/dy=90y^2-6y^2
dp/dy=0 when:
90y^2-6y^3=0
6y^2(15-y)=0, we know y>0 so
y=15, since x=(60-3y)/2
x=7.5
(We solved it this way because otherwise you get quartic equations and cubic derivatives, yuck :P)
Answer:
A
Step-by-step explanation:
Since F(x) is opening downwards the x component must be multiplied by a - number. The number in the parentheses represents horizontal movement, but it must be remember that if negative it moves right and if positive it moves left. The number outside the parentheses represents represents vertical movement and is more intuitive, where positive is up and negative is down. Keeping this in mind it should be A
Her friends drink 5/24 gallons of lemonade. (I hope I'm right)
For this case we must take into account the following conversions of units:
1lb = 16 oz
1 lb = 0.454 kg
Applying the conversion of units we have:
(0.800) * (1 / 0.454) * (16/1) = 28.1938326
Rounding off we have:
28.2 oz
Answer:
it needs 28.2 oz of flour
