\large{ \tt{❃ \: EXPLANATION}} :

  • Firstly , You'll have to know the formula of a³ - b³ i.e a³ - b³ = ( a - b ) ( a² + ab + b² )

  • What's the cube root of 1000 ? - It's 10 ! How ?
  1. \sqrt[3]{1000}   =   \sqrt[3]{ \underline{10} \times \underline{ 1 0}  \times \underline{ 10} } =  \boxed{10}

\large{ \tt{❁ \: LET'S\: START}} :

\large{ \bf{ ❀ \: \ {x}^{3 }  - 1000}}

- Write the number into the exponential form with the exponent 3 :

\large{ \bf{↦ {x}^{3}  -  {10}^{3} }}

- Here , Suppose ' x ' as ' a ' & ' 10 ' as ' b '. Use the formula of a³ - b³ :

↦{ \large{ \bf{(x - 10)( {x}^{2}  + x \times 10 +  {10}^{2} }}})

↦  \boxed{\large{ \bf{(x - 10)( {x}^{2} + 10x + 100) }}}

  • Hence , Second option is the correct choice !

Answer:

Answer: (7,-2)

Step-by-step explanation:

Look at the formula

1) (x – h)^2 + (y – k)^2 = r2

the center is described by (h,k)

now look at

(x – 7)^2 + (y +2)^2 = 25

here h=7

but k= -2 because is (y+2) =(y-(-2))

ANSWER

Given,

Diameter of the base of the cylindrical container d=56 cm

Hence, radius of the base of the cylindrical container r=

56

=28 cm

Dimensions of rectangular solid is (32 cm×22 cm×14 cm)

We know that when a body is completely submerged in a container containing water,

the rise in the volume of water in the container is equal to the volume of the body.

Let, the water rises to a height h.

Hence,

Volume of water rises in cylindrical container =Volume of the rectangular solid

Step-by-step explanation:

the y-intercept is 1 because it's on the y(axis). the line from 1 goes down 1 over three so the slope is 1/3.

your equation would be y=1/3x+1
