Javier works in a photo lab and needs to make a reduced copy of a photograph that is 8 inches long. The customer wants the copy

Scrat [10]

Answer:

Javier should not press the button five time.

Step-by-step explanation:

The given scenario says that Javier claimed that pressing the button 5 times would be enough to fulfill the customer's request. So, lets check that.

We will start at 8 inches.

Press once, $8-0.12*8=7.04$ inches.

Pressing again, we get $7.04-.12*7.04=6.1952$ inches.

Again pressing we get $6.1952-.12*6.1952 = 5.451776$ inches.

Again we get $5.451776-.12*5.451776 =4.79756288$ inches.

Again we get $4.79756288-.12*4.79756288= 4.221855334$ inches.

We can clearly see here that pressing 4 or 5 times does not get 4.5 inches exactly as claimed by Javier.

Therefore, Javier claim is not right and his boss is right.

How do I simplify this (sinx)/(secx+1)

pochemuha

Answer:

Step-by-step explanation:

$\frac{sin~x}{sec~x+1} =\frac{sin~x}{\frac{1}{cos~x}+1 } =\frac{sin~x~cos~x}{1+cos~x} \\=\frac{sin~x~cos~x}{1+cos~x} \times \frac{1-cos~x}{1-cos~x} \\=\frac{sin~x~cos~x(1-cos~x)}{1-cos^2 x} \\=\frac{sin~x~cos~x(1-cos~x)}{sin^2x} \\=\frac{cos~x(1-cos~x)}{sin~x} \\=cos ~x(csc~x-cot~x)\\or\\=cot~x(1-cos~x)$

What can be concluded about the polygon?

cupoosta [38]

You can conclude that the sides are parallel because the slope of the opposites are the same. (Second option).

You can conclude that the polygon is a rectangle since it has 4 90º angles, and 4 sides, each one parallel to the other and of the same lenght as it's parallel. (Last option).

Answer:

$\boxed{\bf~The~second~and~last~options~are~correct.}$

Hope it helped,
