Is 7/8 or 11/10 closer to 1? How did you decide anybody help please?
erik [133]

Let

A-----> \frac{7}{8}

B-----> \frac{11}{10}

C-----> 1

we know that

Point A-------> Multiply numerator and denominator by 10

\frac{7*10}{8*10} =\frac{70}{80}

Point B-------> Multiply numerator and denominator by 8

\frac{11*8}{10*8} =\frac{88}{80}

Point C-------> Multiply numerator and denominator by 80

\frac{1*80}{1*80} =\frac{80}{80}

Find the distance Point A to Point C

\frac{80}{80} -\frac{70}{80} =\frac{10}{80}

Find the distance Point B to Point C

\frac{88}{80} -\frac{80}{80} =\frac{8}{80}

therefore

\frac{8}{80} < \frac{10}{80}

Point B is closer to Point C

\frac{11}{10} is closer to 1

the answer is

\frac{11}{10} is closer to 1

For what real value of $v$ is $\frac{-21-\sqrt{301}}{10}$ a root of $5x^2+21x+v$?
Degger [83]

Answer:

v = 7

is the value for which

x = (-21 - √301)/10

is a solution to the quadratic equation

5x² + 21x + v = 0

Step-by-step explanation:

Given that

x = (-21 - √301)/10 .....................(1)

is a root of the quadratic equation

5x² + 21x + v = 0 ........................(2)

We want to find the value of v foe which the equation is true.

Consider the quadratic formula

x = [-b ± √(b² - 4av)]/2a ..................(3)

Comparing (3) with (2), notice that

b = 21

2a = 10

=> a = 10/2 = 5

and

b² - 4av = 301

=> 21² - 4(5)v = 301

-20v = 301 - 441

-20v = -140

v = -140/(-20)

v = 7

That is a = 5, b = 21, and v = 7

The equation is then

5x² + 21x + 7 = 0

What group of americans were helped by andrew jackson
Ugo [173]
Jackson achieved national distinction for his performance in the War of 1812. In the Battle of Horseshoe Bend, he oversaw the destruction of 15 percent of the Creek population; the treaty that ended hostilities forced the Creek to cede over 20 million acres of their ancestral lands. Jackson is most remembered for his performance in the Battle of New Orleans, during which he led his troops to a decisive victory over the British after the Treaty of Ghent had been signed and hostilities had officially ended.

In December 1817, President James Monroe authorized Jackson to lead an offensive against the Seminole and Creek Indians in Georgia and Florida, sparking the First Seminole War. Jackson ordered his troops to destroy Seminole settlements, capture a Spanish fort, and execute two British citizens whom Jackson blamed for supporting the Seminoles against white people. In 1819, the Spanish ceded all of Florida to the United States in the Adams-Onís—or Transcontinental—Treaty.
