Social Studies
1 answer:
topjm [15]2 years ago

As this shows, once a self-contradiction is shown, the convention for writing an Indirect Proof is to then quit the indented sequence and write just the conclusion, followed by the justification “IP.” This means that the Indirect Proof has been accomplished: by showing that the assumption led to a self-contradiction

10. Problems and Applications Q10 Consider public policy aimed at smoking. Studies indicate that the price elasticity of demand
andrew-mc [135]

From the statements given the ones that are consistent with this result are:

1-Teenagers do not have as much income as adults, so they are more price sensitive.

The study talks about increasing the price to reduce consumption and clarifies that adolescents are more likely to adapt to changes in price. Which is different from that established in the declaration. But the other two options on adults are even less consistent with the statement about the study.

A rectangular page is designed to contain 81 square inches of print. The margins at the top and bottom of the page are each 1 in
Nookie1986 [14]

Answer:

x = 11.02 inch by  y = 7.35 inch

Explanation:

Let the width of the print be = x

Then the width of the page is x + (1.5+1.5) = x + 3

Let the height of the print be = y

Then the height of the page is y + (1+1) = y + 2

Given the area of the print is 81 square inches

That means, xy = 81

Therefore, y = \frac{81}{x}

Therefore, the area of the page is

A = (x + 3)(y + 2)

   = (x + 3)(\frac{81}{x} + 2)

Now for least amount of paper to be used,

\frac{dA}{dx}=(x+3)(\frac{81}{x}+2)

\frac{dA}{dx}= \left (\frac{81}{x}+2  \right )+\left ( x+3 \right )\left ( -\frac{81}{x^{2}} \right )=0

\frac{81+2x}{x}=\frac{(x+3)(81)}{x^{2}}

81x+2x^{2}=81x+81\times 3

2x^{2}=243

x = 11.02 inch

Now y = \frac{81}{x}

          = \frac{81}{11.02}

          = 7.35 inch

Therefore the dimensions of thr page for the least amount of paper is x = 11.02 inch by  y = 7.35 inch

enot [183]

Answer:

He is experiencing puberty.

Explanation:

In simple words, puberty refers to the phase in which boys and girls become sexually mature. It usually starts around age 12 to 14 (although it can occur a few years sooner) and also implies physical changes.

Among other things, boys develop a higher production of testosterone, the principal male sex hormone. That would explain why James is experiencing these changes while reading the story.

During the course of fish evolution two of the gill slits slowly evolved into ____________.
xeze [42]

in the course of fish evolution, two of the gill slits slowly advanced into the jaws.

The evolution of fish started about 530 million years in the past at some point during the Cambrian explosion. It become during this time that the early chordates advanced the cranium and the vertebral column, main to the first craniates and vertebrates. the first fish lineages belong to the Agnatha or jawless fish.

The earliest fish, corresponding to living hagfish, developed about 550 million years in the past. Diversifications that in the end advanced in fish include an entire vertebral column, jaws, and an endoskeleton manufactured from bones in preference to cartilage. Fish live in the course of the sea and in freshwater lakes and streams.

New studies have uncovered the genetic foundation of gill covers in fish, which came about over 430 million years ago. It sheds light on one of the most essential evolutionary traits for fish, in addition to over vertebrates.

In jawless fishes, a sequence of gills opened behind the mouth, and those gills became supported by way of cartilaginous elements. the primary set of these elements surrounded the mouth to shape the jaw.
