f(2,-1)=2^2-(-1)^2=3

so we're considering the level curve

x^2-y^2=3

The tangent line to this curve at (2, -1) will be the value of \dfrac{\mathrm dy}{\mathrm dx} at this point. Differentiating yields

2x-2y\dfrac{\mathrm dy}{\mathrm dx}=0\implies\dfrac{\mathrm dy}{\mathrm dx}=\dfrac xy

and so the slope of the tangent would be \dfrac2{-1}=-2.

The tangent line then has equation

y-(-1)=-2(x-2)\implies y=-2x+3

The net would be 51 feet long to stretch from one side of the court to the other

<h3>What are scaled drawings?</h3>

Scale drawings are drawings that shows a diagram with another proportional dimensions

The scale ratio of the diagram is given as:

Scale = 1 inch = 12 feet

The length of the net is given as:

Length = 4.25 inches

So, the actual length of the net is:

Length = 4.25 \times 12

Evaluate the product

Length = 51

Hence, the net would be 51 feet long, if stretched across the court

Answer:

74.5%

Step-by-step explanation:

The total number of people sampled is 1000 people.

There are 745 people who where corrective lenses.

Percent is (part)/(whole); in this case, the part is 745 and the whole is 1000, so:

745/1000 = 74.5%

Thus, the answer is 74.5%.

Hope this helps!
