The optimum diameter d (in millimeters) of the pinhole in a pinhole camera can be modeled by d=1.9[(5.5×10−4)L]1/2, where is the

The optimum pinhole diameter for a camera box with a length of 10 centimeters is 0.446 mm

<h3><u>Solution:</u></h3>

Given that,

<h3><u>The optimum diameter d (in millimeters) of the pinhole in a pinhole camera can be modeled by:</u></h3>

$d = 1.9[(5.5 \times 10^{-4})l]^{\frac{1}{2}}$

where l is the length (in millimeters) of the camera box

<h3><u>Find the optimum pinhole diameter for a camera box with a length of 10 centimeters</u></h3>

l = 10 cm

We know that,

10 cm = 100 mm

<em><u>Therefore, plug in l = 100 in given formula</u></em>

$d = 1.9[(5.5 \times 10^{-4}) \times 100]^{\frac{1}{2}}\\\\d = 1.9[5.5 \times 10^{-4} \times 10^2]^{\frac{1}{2}}\\\\d = 1.9[5.5 \times 10^{-2}]^{\frac{1}{2}}\\\\d = 1.9 \times 5.5^{\frac{1}{2} \times 10^{-1}}\\\\d = 0.19 \times 2.345207\\\\d = 0.4455 \approx 0.446$

Thus the optimum pinhole diameter for a camera box with a length of 10 centimeters is 0.446 mm

Answer:

Step-by-step explanation:

A(-6,2) =>A'(-5, -1)

B(-5,4) =>B'( -4,1)

C(-2,4)=> C'(-1,1)

D( 1,2) => D'(2,-1)

we move all these points to (x+1, y-3)
