Answer:
less than
Step-by-step explanation:
time is minutes and volume is already gallons and the 2 for gallons is at 4 minutes marking it 1 gallon per 2 minutes or half a gallon per minute
Discriminant = b^2 - 4ac, where a, b and c come from the form of the quadratic equation as ax^2 + bx + c
Discriminant = (4)^2 - 4(1)(5)
= 16 - 20
= -4
-4 < 0, therefor there are no roots
(If the discriminant = 0, then there is one root
If the discriminant > 0, there are two roots, and if it is a perfect square (eg. 4, 9, 16, etc.) then there are two rational roots
If the discriminant < 0, there are no roots)
The rate of change in z at (4,9) as we change x but hold y fixed is =
3/[2sqrt(3x+2y)] put x = 4 , y = 9 = 3/[2sqrt(12+18) = 3/[2sqrt(30)] The
rate of change in z at (4,9) as we change y but hold x fixed is =
1/sqrt(3x+2y) put x = 4, y =9 = 1/sqrt(30)
Answer:
84
Step-by-step explanation:
is x 140
---- SO ... ------- = --------
of 60 100
(hit like pls)
60*140=100x
8400=100x
/100 /100
-------------------
84 = x
Answer: 0.71428 or 5:7 or 5/7
Step-by-step explanation: just divide on a calculator
