Over the last 100 years, humans have made great strides in developing technologies that can forecast severe weather before it happens. however, despite the best scientific data and tools available, we are still sometimes surprised by weather. in 2015, an unexpected spring storm produced severe tornadoes in iowa. sometimes—even with computer models and satellite imaging—tornadoes, hurricanes, and other severe storms cause unspeakable damage to communities. do you think humans will ever be able to forecast severe weather with 100% accuracy? what challenges do we face in developing technology that can do so? besides forecasting tools, what other technology is needed to prevent severe storms from causing disasters? do you think all countries have the financial capability to support the development and operation of these technologies? if not, do you think there is an ethical obligation for countries with more financial resources to help poorer countries access these technologies?

Answers

The modern civilization is already able to predict climate conditions with nearly 100% precision.

What is precision in meteorology?

Precision in meteorology makes reference to the ability to predict climate conditions in the median-long periods of time.

The development of technologies to accurately predict climate conditions will largely depend on computer models capable of integrating huge volumes of data.

The main challenge for the development of this type of technology is associated with the impossibility to manage complex climate factors in controlled (experimental) conditions.

In general, developing countries don't have the financial support to develop and sustain this type of technology.

Given p(x) = negative4(x minus 15)2 + 2, what is the value of p(7)?

Answers

the value of P(7), given P(x) = negative4(x minus 15)2 + 2 is 1721.

The problem above can be solved using the ideal of polynomial.

What is a Polynomial?

Polynomials are mathematical expressions whereby the highest degree of their unknown is 2 and above.

Given:

P(x) = negative4(x minus 15)2 + 2P(x) = -4(x-15)²+2

Expand the expression

P(x) = -4(x²-30x+225)+2P(x) = -4x²+120x+900+2P(x) = -4x²+120x+902

To find P(7), we subtitute 7 as the value of x in the expression above

P(7) = -4(7²)+120(7)+909P(7) = -28+840+909P(7) = 1721

Hence, the value of P(7), given P(x) = negative4(x minus 15)2 + 2 is 1721.

draw the structural formula for the product formed by the reaction of the compound shown below with propylmagnesium bromide followed by aqueous hcl.

Answers

To draw the structural formula of the product first identify both the reactants and possible products, and then draw a structure to represent the product.

How to know what is the product of a reaction?

The product of a reaction derives from the reactants or initial substances. Due to this, the best way to identify the product is to identify the reactants and determine how they interact. For example:

Are the reactans joining to form one product?Is a certain atom trasnferring from one strucutre to another?Among others.

How to draw a structural formula?Identify the number of carbons in the product as this is usually the base for a structural formula and represent them, for this you can use C to represent each carbon atom.Place other atoms in the structure by making sure to relate the atoms to the correct carbon atom.Remember to represent the type of bonds between atoms. For example two lines connecting two atoms means there is a double bond.

Note: This question is incomplete because ther is not information about the compound; due to this, the answer is based on general knowledge.

The passage from "Two Kinds.”

"You want me to be something that I’m not!” I sobbed. "I’ll never be the kind of daughter you want me to be!” "Only two kinds of daughters,” she shouted in Chinese. "Those who are obedient and those who follow their own mind! Only one kind of daughter can live in this house. Obedient daughter!”

"Then I wish I weren’t your daughter. I wish you weren’t my mother,” I shouted. As I said these things I got scared. It felt like worms and toads and slimy things crawling out of my chest, but it also felt good, as if this awful side of me had surfaced, at last. "Too late change this,” said my mother shrilly. And I could sense her anger rising to its breaking point. I wanted see it spill over. And that’s when I remembered the babies she had lost in China, the ones we never talked about. "Then I wish I’d never been born!” I shouted. "I wish I were dead! Like them.

In order to figure out the distance, what do I do?

Answers

Answer:

d = square root of {(x2 - x1)^2 + (y2-y1)^2}

Explanation:

If you're referring to math-

the distance is equal to (the second x value minus the first x value)^2 plus (the second y value minus the first y value)^2

For example: this is my imaginary ordered pair, I want to find the distance between the points- (2,4) and (3,6)

So d= (3-2)^2 - (6-4)^2  all under a square root

3-2 is = to 1, and 1 squared is just 1.

6-4 is = to 2, and 2 squared is 4.

4+1 is = 5.

So your answer would be the square root of 5.

If your answer ended up as, for example, the square root of 16, you would go a step further and your answer, or distance would be 4, since 4^2 is 16
