First find Divisor

  • Two zeros are -3,-2

\\ \sf\longmapsto x^2-(-3-2)+(-3)(-2)

\\ \sf\longmapsto x^2+5x+6

Dividend given by

\\ \sf\longmapsto x^4-x^3-16x^2+4x+48

We know

\boxed{\sf Dividend=Divisor\times Quotient +Remainder}

  • Remainder is 0

\\ \sf\longmapsto Dividend=Divisor\times Quotient

\\ \sf\longmapsto Quotient=\dfrac{Dividend}{Divisor}

\\ \sf\longmapsto \dfrac{x^4-x^3-16x^2+4x+48}{x^2+5x+6}

\\ \sf\longmapsto x^2-6x+8

Now factor

\\ \sf\longmapsto x^2-6x+8=0

\\ \sf\longmapsto x^2-4x-2x+8=0

\\ \sf\longmapsto x(x-4)-2(x-4)=0

\\ \sf\longmapsto (x-4)(x-2)=0

\\ \sf\longmapsto x-4=0\:or\:x-2=0

\\ \sf\longmapsto x=4\:or\:x=2

Hence all zeros are

  • 2,-2,-3,4

Cube and cube roots 27000<br>​
boyakko [2]

Answer:

lcm for cuberoot

2*2*2*5*5*5*3*3*3

for cuberoot we will make pairs of common three numbers and write them one time

2*5*3

30

check 30*30*30=27000

cube

multiply 27000 three times with itself

19683000000000.0 is the answer

Tell whether the ordered pair is a solution of the linear system. (-4,-6); -3x+y=6, -2x+y=-8
harkovskaia [24]
Plug them in... -4=x -5=y

-3x-4+-6=6 (check)
-3x-4=12-6=6 (ordered pair works with this equation)

-2x-4+-6=-8 (check)
-2x-4=8-6=2 (ordered pair does not work with this equation)

Therefore the ordered pair IS NOT the solution.

Hope this helps :)

Amy jogs 1/3 of a mile in 1/15 of an hour, while john takes 1/30 of an hour to jog 1/5 of a mile. If they continue at this rate,
jolli1 [7]

Step-by-step explanation:

Given that,

Amy jogs 1/3 of a mile in 1/15 of an hour and john takes 1/30 of an hour to jog 1/5 of a mile.

Speed of Amy,

v_1=\dfrac{\dfrac{1}{3}\ miles }{\dfrac{1}{15}\ h}=5\ mph

Speed of John,

v_2=\dfrac{\dfrac{1}{5}\ miles }{\dfrac{1}{30}\ h}=6\ mph

John will jog farther in one hour as he is moving with faster speed. The speed of John is 1 mph more than Amy.

What is a artafart and a Earth quack?
bekas [8.4K]
Aftershocks occur after the most major part of an earth quake happens. Earthquakes occur at fault lines near the tectonic border. They occur because of the sudden movement for staying rigid while they were edging closer and closer. So the sudden movement releases a large amount of tension buried deep below the earth creating or resulting in an earthquake.
