The fuel tank of a certain airplane can hold up to 300 gallons of fuel. Let W be the total weight of the airplane (in pounds). L

et F be the total amount of fuel in its tank (in gallons). Suppose that W=6F+4000 gives W as a function of F . Identify the correct description of the values in both the domain and range of the function. Then, for each, choose the most appropriate set of values.

The point P(5, −4) lies on the curve y = 4/(4 − x).
dalvyx [7]

Answer:

4

Step-by-step explanation:

Slope refers to the steepness of the line.

Slope is equal to change in value of y divided by change in value of x.

The slope of the secant line is given by \frac{f(x)-f(a)}{x-a}.

Given points are P\left ( 5,-4 \right )\,,\,Q\left ( x,\frac{4}{4-x} \right )

So, slope of the secant line is \frac{\frac{4}{4-x}+4}{x-5}=\frac{4+4(4-x)}{(x-5)(4-x)}=\frac{20-4x}{(x-5)(4-x)}=\frac{-4(x-5)}{(x-5)(4-x)}=\frac{-4}{4-x}=\frac{4}{x-4}

(i) At x = 4.9,

\frac{4}{4.9-4}=\frac{4}{0.9}=4.444444

(ii) At x = 4.99,

\frac{4}{4.99-4}=\frac{4}{0.99}=4.040404

(iii) At x = 4.999,

\frac{4}{4.999-4}=\frac{4}{0.999}=4.004004

(iv) At x = 4.9999,

\frac{4}{4.9999-4}=\frac{4}{0.9999}=4.0004

(v) At x =5.1,

\frac{4}{5.1-4}=\frac{4}{1.1}=3.636364

(vi)

At x = 5.01,

\frac{4}{5.01-4}=\frac{4}{1.01}=3.960396

(vii) At x = 5.001,

\frac{4}{5.001-4}=\frac{4}{1.001}=3.996004

(viii) At x = 5.0001,

\frac{4}{5.0001-4}=\frac{4}{1.0001}=3.9996

(b)

Slope of the tangent line is 4.

How would I do this?
Lelu [443]
I'm not sure about part B, but part A will have the answer "if Ron eats lunch today, then he will drink a glass of milk" (without quotes of course)

The idea is that we have these arguments in symbolic form
P = Ron eats lunch today
Q = Ron eats a sandwich
R = Ron will drink a glass of milk

The format is 
"If P then Q" ----> "if Q then R"  so therefore "If P then R"

We see that P leads to Q, then Q leads to R. So overall P leads to R. We connect them as a chain of sorts. We can skip over Q since we know the first point will lead to the last. Think of it as a shortcut of sorts.
