Answer:

Yes, I agree

Step-by-step explanation:

For the cubic function

A cubic function is represented as:

[tex]f(x)=ax^3+bx^2+cx+d[/tex]

A cubic function may have 1, 2 or 3 x intercepts. This is shown below

For 3 x intercepts

[tex]y = x^3 - x[/tex]

Equate y to 0

[tex]x^3 - x = 0[/tex]

Expand

[tex]x(x^2 - 1) = 0[/tex]

Express [tex]x^2 - 1[/tex] as difference of two squares

[tex]x(x - 1)(x +1 ) = 0[/tex]

x = 0 or 1 or -1

For 2 x intercepts

[tex]y = x^3 - x[/tex]

[tex]y =(x-5)^2)(x+7)[/tex]

Equate y to 0

[tex](x-5)^2(x+7) = 0[/tex]

Expand

[tex](x-5)(x-5)(x+7) = 0[/tex]

x= 5 or x = -7

For 1 x intercept

[tex]y = x^3[/tex]

Equate y to 0

[tex]x^3 = 0[/tex]

Take cube roots of both sides

[tex]x = 0[/tex]

It has been shown above that a cubic function may have 1, 2 or 3.

So, I agree to the statement

For the quadratic function

A quadratic function will not have any x intercept when the function can not be factorized;

E.g.

[tex]y = x^2 + x + 17[/tex]

The above function has no x intercept.

A quadratic function will have at least 1 x intercept when the function can be factorized;

E.g.

[tex]y = x^2- 6x + 9[/tex]

Equate y to 0

[tex]x^2- 6x + 9 = 0[/tex]

Expand

[tex]x^2 - 3x - 3x + 9 = 0[/tex]

[tex](x - 3)(x-3) = 0[/tex]

[tex]x = 3[/tex]

We've shown that a quadratic may have no x intercept, and it may also have x intercept(s)

Hence, I agree to both statement

Answer:

C : JK is longer than JL.

Step-by-step explanation:

We can use the pythagorean theorem to solve this question, if we think of lines JK and JL as hypotenuse lengths. Triangle JK has side lengths of 5 and 5. Triangle JL has side lengths of 1 and 5. JK is longer than JL.

Answer:

C

Step-by-step explanation:

use the distance formula d= [tex]\sqrt (x2-x1)2+(y2-y1)2[/tex]

The distance of J to K is 6.403124

The distance of J to L is 5.09902

The size of the angle x is 13°

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

From the figure,

Let the triangle having ∠x have the following angles:

∠A and ∠B.

Now,

∠A is opposite to 85°.

So,

∠A = 85°

98° and one angle are corresponding angles.

So,

One angle = 98°

Now,

One angle and ∠B is a straight angle.

So,

∠B + 98 = 180

∠B = 180 - 98

∠B = 82°

Now,

The sum of the triangle is 180.

This means,

x + 82 + 85 = 180

x = 180 - 167

x = 13

Thus,

The value of x is 13.

Answer:

Step-by-step explanation:

The amount of water in the mix is 2/(5+2) = 2/7 of the volume of the mix. That amount is ...

  (2/7)(21 liters) = 6 liters

Then the other 21-6 = 15 liters are antifreeze.

A) To make the mix 1 : 1, 15-6 = 9 liters of water need to be added.

Step-by-step explanation:

The family’s leaders have pulled off three of the great marketing triumphs of the modern era: The first is selling OxyContin; the second is promoting the Sackler name; and the third is ensuring that, as far as the public is aware, the first and the second have nothing to do with one another.

To the extent that the Sacklers have cultivated a reputation, it’s for being earnest healers, judicious stewards of scientific progress, and connoisseurs of old and beautiful things. Few are aware that during the crucial period of OxyContin’s development and promotion, Sackler family members actively led Purdue’s day-to-day affairs, filling the majority of its board slots and supplying top executives. By any assessment, the family’s leaders have pulled off three of the great marketing triumphs of the modern era: The first is selling OxyContin; the second is promoting the Sackler name; and the third is ensuring that, as far as the public is aware, the first and the second have nothing to do with one another.

If you head north on I-95 through Stamford, Connecticut, you will spot, on the left, a giant misshapen glass cube. Along the building’s top edge, white lettering spells out ONE STAMFORD FORUM. No markings visible from the highway indicate the presence of the building’s owner and chief occupant, Purdue Pharma.

Originally known as Purdue Frederick, the first iteration of the company was founded in 1892 on New York’s Lower East Side as a peddler of patent medicines. For decades, it sustained itself with sales of Gray’s Glycerine Tonic, a sherry-based liquid of “broad application” marketed as a remedy for everything from anemia to tuberculosis. The company was purchased in 1952 by Arthur Sackler, thirty-nine, and was run by his brothers, Mortimer, thirty- six, and Raymond, thirty-two. The Sackler brothers came from a family of Jewish immigrants in Flatbush, Brooklyn. Arthur was a headstrong and ambitious provider, setting the tone—and often choosing the path—for his younger brothers. After attending medical school on Arthur’s dime, Mortimer and Raymond followed him to jobs at the Creedmoor psychiatric hospital in Queens. There, they coauthored more than one hundred studies on the biochemical roots of mental illness. The brothers’ research was promising—they were among the first to identify a link between psychosis and the hormone cortisone—but their findings were mostly ignored by their professional peers, who, in keeping with the era, favored a Freudian model of mental illness.

Concurrent with his psychiatric work, Arthur Sackler made his name in pharmaceutical advertising, which at the time consisted al

Answer:

204.4 miles

Step-by-step explanation:

Given data

we are told that on the map the distance is 14.6cm

scale

1cm=14miles

hence if

        1cm represents 14miles

then  14.6 cm will be x

cross multiply

x= 14.6*14

x=204.4 miles

Hence the distance is 204.4 miles
