Answer:
The approximate speed of the object when it hits the ground is 63.568 meters per second.
Explanation:
The height of the object launched vertically upward is represented by the function [tex]h(t) = 200+11\cdot t -4.9\cdot t^{2}[/tex]. The approximate speed of the object when it hits the ground occurs when [tex]h(t) = 0[/tex]. Then, we solve the resulting second-order polynomial by the Quadratic Formula:
[tex]-4.9\cdot t^{2}+11\cdot t +200 = 0[/tex] (1)
The roots associated to this polynomial are, respectively:
[tex]t_{1}\approx 7.609\,s[/tex] and [tex]t_{2} \approx -5.364\,s[/tex]
Given that time is a positive variable, the only solution that is physically reasonable is:
[tex]t\approx 7.609\,s[/tex]
The function velocity is the first derivative of the function defined at the commencement of the explanation, that is:
[tex]v(t) = 11-9.8\cdot t[/tex] (2)
If we know that [tex]t\approx 7.609\,s[/tex], then the approximate velocity of the object when it hits the ground is:
[tex]v(7.609) = 11-9.8\cdot (7.609)[/tex]
[tex]v(7.609) = -63.568\,\frac{m}{s}[/tex]
The speed is the magnitude of this velocity. Therefore, the approximate speed of the object when it hits the ground is 63.568 meters per second.

In which of the following should the random variable X not be modeled with a geometric distribution?
Answer:
D)
In a bag of 30 different colored candies, about 20% are red. One candy will be selected one at a time without replacement, and its color will be recorded. Let X represent the number of candies selected before red is selected.
Explanation:
The selections are not independent because they do sampling without replacement which makes it so there is not an equal chance of being selected each round.
The question can be solved by evaluating the assumptions for a geometric distribution. Hence, since the probability for success is not the same for each trial, then the option D cannot be modeled using a geometric distribution.
One of the assumptions to consider before the use of a geometric distribution can be valid is that, the probability of success must be the same for each outcome. In the option D, selection is done without replacement, meaning that, the number total possible outcome will decrease as we make each selection and will also depend on how the colors are being chosen.Hence, the probability success will differ for each outcome, thus the option D is correct.

The correct answer to this open question is the following.
“If we remembered everything, we should on most occasions be as ill off as if we remembered nothing.” William James.
What Willia James tried to share with this quote was that people have to forget and live. That it is not a good thing to carry the burdens of life, generating resentments all your life. Whatever happened one year ago or ten years ago, it's in the past. To be happy you have to free of those burdens that come from time to time and produce bad feelings, just by reminding you what happened or who made what to who.
So for me is a good quote to remind ourselves to forgive and forget, and keep on living a happy life without resentments.

II and III only
I and II only
Answer:
one death of crops and two rise of local water table
The side effects of waterlogging crops are the death of crops and the rise in the local water table. The correct option is c, II, and III only.
What is water clogging crops?Waterlogging reduces the amount of oxygen in the root zone, which slows plant growth. Waterlogging alters the chemical equilibria of many elements, which then enter the soil-water solution in their ionic forms, increasing the reduction potential of the soil.
Some grains can withstand waterlogging better than others: Canola and the majority of grain legumes are more prone to waterlogging than cereals and faba beans.
The grain legumes fava bean, yellow lupin, grass pea, narrow-leafed lupin, chickpea, lentil, and field pea are listed in decreasing order of tolerance.
Therefore, the correct option is c, II, and III only.

TIMED HURRY PLEASE( 40 points and a brainlist) Read the excerpt from William Seward’s The Building of the Erie Canal.
The public debt for canals in 1825 amounted to seven and a half million dollars—all of which, it must be recorded to the honor of the State and the country, had been borrowed of American capitalists—and the annual interest thereon, to three hundred seventy-six thousand dollars. The Governor estimated that the tolls for the year would exceed three hundred ten thousand dollars; that the duties on salt would amount to one hundred thousand dollars, and that these, with the other income of the canal fund, would produce a revenue exceeding, by three hundred thousand dollars, the interest on the canal debt. He stated also that ten thousand boats had passed the junction of the canals near tide-water during the previous season. Remarking that the creative power of internal improvement was manifested in the flourishing villages which had sprung up or been extended; in the increase of towns; and, above all, in the prosperity of the city of New York. And noticing the fact that three thousand buildings had been erected in that city during the preceding year, Clinton predicted that in fifteen years its population would be doubled, and that in thirty years that metropolis would be the third city in the civilized world, and the second, if not the first, in commerce.
Why might the bulding of the Erie Canal be considered controversial?
It had a negative environmental impact.
It was not long enough.
It was publicly financed.
It was an economic failure.
so we get the points just by reading it and writing something
Answer:
C) It was publicly financed
Explanation:
The Erie Canal was one of the largest and most controversial construction projects undertaken in the United States during the nineteenth century. ... Western farmers were able to ship their produce directly to American markets without having to go through Canadian waters
