the roots of f(x)=-2x^2+8x+13 are __________and __________ the vertex of the parabola is at _________

Answer: the vertex of the parabola is at (2,21)

The roots are down below. I didn’t know how to type them out

Explanation:

Roots:

Move the terms aside.

x + 2x^2 - 8x - 13 = 0

Simplify it:

-7x + 2x^2 - 13 = 0

And just use the quadratic formula

“ x = -b + sqrt(b^2 - 4ac)/2a , x = -b— sqrt(b^2 - 4ac)/2a “

and it should end up looking like the picture down below.

Read the passage and answer the question.

[1]Nothing that comes from the desert expresses its extremes better than the unhappy growth of the
tree yuccas.Tormented, thin forests of it stalk drearily in the high mesas, particularly in that
triangular slip that fans out eastward from the meeting of the Sierras and coastwise hills. The
yucca bristles with bayonet-pointed leaves, dull green, growing shaggy with age like an old
[5] man's tangled gray beard, tipped with panicles of foul, greenish blooms. After its death, which is
slow, the ghostly hollow network of its woody skeleton, with hardly power to rot, makes even
the moonlight fearful. But it isn't always this way. Before the yucca has come to flower, while
yet its bloom is a luxurious, creamy, cone-shaped bud of the size of a small cabbage, full of
sugary sap, the Indians twist it deftly out of its fence of daggers and roast the prize for their
[10] own delectation.

Why does the author use the word "prize" to describe the bloom of the yucca tree (line 9)?

To communicate how rare it is to find the bloom
To emphasize the deliciousness of the bloom
To highlight the color and shape of the bloom
To show how to prepare the bloom for eating

Essay on bullying is a terrible problem that need to stop.

The labor practices of the fast food industry have their origins in the assembly line systems adopted by American manufacturers in the early twentieth century. Business historian Alfred D. Chandler has argued that a high rate of “throughput” was the most important aspect of these mass production systems. A factory’s throughput is the speed and volume of its flow — a much more crucial measurement, according to Chandler, than the number of workers it employs or the value of its machinery. With innovative technology and the proper organization, a small number of workers can produce an enormous amount of goods cheaply. Throughput is all about increasing the speed of assembly, about doing things faster in order to make more.


—Fast Food Nation, Eric Schlosser


Identify the claim made in this passage.

Technology increases “throughput.”

The fast-food industry is based on the mass production idea of “throughput.”
