If A(t) is the amount of salt in the tank at time t, then A(0) = 50 g and
A'(t) = (1 g/L)*(3 L/min) - (A(t)/120 g/L)*(3 L/min)
Multiply both sides by 
, so that the left side can be condensed as the derivative of a product:
Integrate both sides and solve for A(t).
Given that A(0) = 50 g, we have
so that the amount of salt in the tank at time t is
I'm pretty sure the simplified answer of (4x^3y^-5)^4 would be 256x^12/y^20 (this is a fraction)
Hope this helps :)
Honestly I tried looking it up to get atleast something, but my best answer would have to be B.
Take this answer with a grain of salt, a lot of it
Answer:
1548 lb
Step-by-step explanation:
Let the truck's weight be w.
Then (1/3)w = 516 lb
Solve for the truck's weight by multiplying both sides of this equation by 3:
w = 1548 lb (Answer B)
Answer:
This is an exponential function
Step-by-step explanation:
f(x)=2(3)^x is one example of the exponential function. Since f(0) = 2(1) = 2, the y-intercept is (0, 2). The x-axis is the horizontal asymptote. The graph begins in Quadrant II, passes through (0, 2) and continues to increase, faster and faster, in Quadrant I. Next time, please be more specific about what you'd like to know.
