Answer: B. -3 and 7
Step-by-step explanation:
To find the zeros, just move the constants to the other side,
x - 7 ⇒ x = 7
x + 3 ⇒ x = -3
If the number is moved to the other side its sign becomes opposite
Hope it helps!
Answer:
7
Step-by-step explanation:
2(3) + 6²/6
Multiply 2x3 and 6² is just multiplying 6x6
6+36/6
Add 6+36
42/6
Divide 42 by 6
7
Answer:
(4,7) and (0,1)
Step-by-step explanation:
(7-4)/(4-2) = 3/ 2, and (4-1)/(2-0) = 3/2.
Let S(t) denote the amount of sugar in the tank at time t. Sugar flows in at a rate of
(0.04 kg/L) * (2 L/min) = 0.08 kg/min = 8/100 kg/min
and flows out at a rate of
(S(t)/1600 kg/L) * (2 L/min) = S(t)/800 kg/min
Then the net flow rate is governed by the differential equation
Solve for S(t):
The left side is the derivative of a product:
Integrate both sides:
There's no sugar in the water at the start, so (a) S(0) = 0, which gives
and so (b) the amount of sugar in the tank at time t is
As , the exponential term vanishes and (c) the tank will eventually contain 64 kg of sugar.
4x345=1380
3000-1380=1621
Answer= Denise would have 1,621 water bottles left
