Answer:

n=0.956

Step-by-step explanation:

2.9+6=8.9 and 5.3n - 4n = -9.3n so, 8.9 - 9.3n = ? so -9.3n = -8.9 and 0.3n = 8.9 so n = 8.9/9.3 which is 0.956

If a tank holds 5000 gallons of water, which drains from the bottom of the tank in 40 minutes, then Torricelli's Law gives the v

pochemuha

Answer:

V'(t) = $-250(1 - \frac{1}{40}t)$

If we know the time, we can plug in the value for "t" in the above derivative and find how much water drained for the given point of t.

Step-by-step explanation:

Given:

V = $5000(1 - \frac{1}{40}t )^2$ , where 0≤t≤40.

Here we have to find the derivative with respect to "t"

We have to use the chain rule to find the derivative.

V'(t) = $2(5000)(1 - \frac{1}{40} t)d/dt (1 - \frac{1}{40}t )$

V'(t) = $2(5000)(1 - \frac{1}{40} t)(-\frac{1}{40} )$

When we simplify the above, we get

V'(t) = $-250(1 - \frac{1}{40}t)$

If we know the time, we can plug in the value for "t" and find how much water drained for the given point of t.

Evaluate the function fx = 4 * 7^t for x= -1 and x=2

Alex73 [517]

Well what i think you're asking here...I apologie if I'm wrong but what I did was

f(-1) = 4 * 7^t = 4/7

and

f(2) = 4 * 7^t = 196.

Is this what you wanted if not I can...try another way.
