Answer:

He is not correct because the answer is 20.5%.

Step-by-step explanation:

Multiply 5400lb by 2 and you get 10,800 and thats how much he filled up. Then half of 60,000lb is 30,000lb and half of 100% is 50%. So 30,000 is equal to 50%. Then half of 30,000lb is 15,000lb and half of 50% is 25%. So 15,000 is equal to 25%. So next subtract 4,200lb from 15,000lb and you get 10,800lb. So then subtract 4.5% from 25% and you get 20.5%. So therefore, 10,800lb is equal to 20.5%.

The point P(1,1/2) lies on the curve y=x/(1+x). (a) If Q is the point (x,x/(1+x)), find the slope of the secant line PQ correct

lukranit [14]

Answer:

See explanation

Step-by-step explanation:

You are given the equation of the curve

$y=\dfrac{x}{1+x}$

Point $P\left(1,\dfrac{1}{2}\right)$ lies on the curve.

Point $Q\left(x,\dfrac{x}{1+x}\right)$ is an arbitrary point on the curve.

The slope of the secant line PQ is

$\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{\frac{x}{1+x}-\frac{1}{2}}{x-1}=\dfrac{\frac{2x-(1+x)}{2(x+1)}}{x-1}=\dfrac{\frac{2x-1-x}{2(x+1)}}{x-1}=\\ \\=\dfrac{\frac{x-1}{2(x+1)}}{x-1}=\dfrac{x-1}{2(x+1)}\cdot \dfrac{1}{x-1}=\dfrac{1}{2(x+1)}\ [\text{When}\ x\neq 1]$
