Yeah, you'd have to use the inverse function to produce this result.

Let's get the inverse function first:

y={ x }^( 3 )-2\n \n { x }^( 3 )=y+2\n \n x=\sqrt [ 3 ]{ y+2 }

\n \n \therefore \quad { f }^( -1 )\left( x \right) =\sqrt [ 3 ]{ x+2 }

Now, we can solve the problem using:

\int _( -1 )^( 25 ){ \sqrt [ 3 ]{ x+2 }  } dx

But to solve the problem more easily we make u=x+2, therefore du/dx=1, therefore du=dx.

When x=25, u=27.

When x=-1, u=1.

Now:

\int _( 1 )^( 27 ){ { u }^{ \frac { 1 }{ 3 }  } } du\n \n ={ \left[ \frac { 3 }{ 4 } { u }^{ \frac { 4 }{ 3 }  } \right]  }_( 1 )^( 27 )

\n \n =\frac { 3 }{ 4 } \cdot { 27 }^{ \frac { 4 }{ 3 }  }-\frac { 3 }{ 4 } \cdot { 1 }^{ \frac { 4 }{ 3 }  }\n \n =\frac { 3 }{ 4 } { \left( { 3 }^( 3 ) \right)  }^{ \frac { 4 }{ 3 }  }-\frac { 3 }{ 4 }

\n \n =\frac { 3 }{ 4 } \cdot { 3 }^( 4 )-\frac { 3 }{ 4 } \n \n =\frac { 3 }{ 4 } \left( { 3 }^( 4 )-1 \right)

\n \n =\frac { 3 }{ 4 } \cdot 80\n \n =60

Simplify: 8x - 6(5x + 6)

Answers

Answer:

-22x-36

Step-by-step explanation:

-6 x 5x = -30x

-6 x 6 =-36

8x - 30x - 36

8x - 30x = - 22x

So, it's -22x - 36.

Answer:

-22 x- 36

Step-by-step explanation:

8x - 6(5x + 6)

-6× 5x= -30x

-6 × 6= -36

8x -30x - 36

-22x - 36

The sum of the roots of the equation (1/2)x^2-(5/4)x-3=0

a.5/2
b.2
c.1/2

Answers

(1/2)x² - (5/4)x - 3 = 0

0.5x² - 1.25x - 3 = 0

Comparing to the quadratic function, ax² + bx + c = 0,    
a = 0.5,  b = -1.2,  c = -3.

Sum of roots = -b/a   =    -(-1.25)/0.5 =    1.25/0.5 = 2.5

2.5 = 5/2  Option (a)
A)5/2 is the answer.
