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
amid [387]

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

Which statement is true about the end behavior of the function represented by the graph?
Zepler [3.9K]

End behavior always involves x approaching positive and negative infinity. So we'll cross off the choice that says "x approaches 1".

The graphs shows both endpoints going down forever. So both endpoints are going to negative infinity regardless if x goes to either infinity.

<h3>Answer: Choice B</h3><h3>As x approaches −∞, f(x) approaches −∞, and as x approaches ∞, f(x) approaches −∞.</h3>

Another way to phrase this would be to say "f(x) approaches negative infinity when x goes to either positive or negative infinity"

52,300,000 in scientific rotation
tatiyna

Answer:

-5.230,0000

Step-by-step explanation:

Your number in decimal form is -52,300,000 . The negative sign remains unchanged. To get to "standard" scientific notation, we move the decimal point so there is only one non-zero digit in front of the decimal point. So, -52,300,000 becomes -5.230,0000
