Two ways in which a camera is better at “seeing” than a human eye.

Mathematics

aev [14]3 years ago

Answer:

<h3>⭐Cameras respond to red, blue and green light using filters placed on top of their photoreceptors. The photoreceptors in a camera are evenly distributed across the lens. In the human eye, however, the cones are concentrated at the centre of the retina. There are no rods at all at the centre of the retina.</h3>

1) With the use you camera, you can apply filters to your photos to make them look better.

2) The camera has better seeing functions than a human eye.

Using linear pairs,

115+5x=180\\\\5x=65\\\\x=\boxed{13}

By the exterior angle theorem,

2y=45+5(13)\\\\2y=45+65\\\\2y=110\\\\y=\boxed{55}

The perimeter of a rectangle is 38 in. The width
Alex_Xolod [135]

Good evening ,

______

Answer:

w=6.5in

___________________

Step-by-step explanation:

L : length

w : width

p : perimeter

38=2L+2w

38 =2(w+6)+2w

38 = 4w+12

38-12=4w

26=4w

26/4=w

w=6.5 in.

What polynomial expressions equal 8x^3+64?
Natali5045456 [20]

Answer:

\displaystyle \boxed{8[x + 2][x^2 - 2x + 4]}

Step-by-step explanation:

Use the Difference of Cubes [(a³ - b³)(a² + 2ab + b²)] to figure this out:

\displaystyle 8x^3 + 64 \\ 8[x^3 + 8] \\ \\ x + 2 = \sqrt[3]{x^3 + 8}

Then, since the divisor\factor is in the form of <em>x - c</em>, use what is called Synthetic Division. Remember, in this formula, −c gives you the OPPOSITE terms of what they really are, so do not forget it. Anyway, here is how it is done:

−2| 1 0 0 8

↓ −2 4 −8

___________

1 −2 4 0 → {x}^{2} - 2x + 4

You start by placing the <em>c</em> in the top left corner, then list all the coefficients of your dividend [x³ + 8]. You bring down the original term closest to <em>c</em> then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder. Finally, your quotient is one degree less than your dividend, so that 1 in your quotient can be an x², the −2x follows right behind it, then 4, giving you the other factor of x^2 - 2x + 4, attaching this to the first two factors you started out your work on:

\displaystyle \boxed{8[x + 2][x^2 - 2x + 4]}
