Mathematics
1 answer:
Ira Lisetskai [31]3 years ago
5 0

Answer:

  see below

Step-by-step explanation:

No simplification is possible as there aren't any factors that can be combined or cancelled. The exponents can be made positive by moving the variable to the other side of the fraction bar.

The applicable rule of exponents is ...

  a^-b = 1/a^b

Solve for m 1/C+1/m=1/z
9966 [12]
Answer:  " m = zC / (C − z) " .
___________________________________
Explanation:
_________________________
Given:  1/C + 1/m = 1/z ;  Solve for "m".

Subtract  "1/C" from each side of the equation:
____________________________________
1/C + 1/m − 1/C = 1/z − 1/C  ;

to get:  1/m = 1/z − 1/C ;
____________________________________
Now, multiply the ENTIRE EQUATION (both sides); by "(mzC"); to get ride of the fractions:
_________________

mzC {1/m = 1/z − 1/C} ;

to get:  zC = mC − mz ;

Factor out an "m" on the "right-hand side" of the equation:

zC = m(C − z) ;  Divide EACH side of the equation by "(C − z)" ; to isolate "m" on one side of the equation;

zC / (C − z) = m(C − z) / m ;  to get:   24/8 = 3  24

zC/ (C − z) = m ;   ↔   m = zC/ (C − z) .

Exercise is mixed —some require integration by parts, while others can be integrated by using techniques discussed in the chapte
wlad13 [49]

Answer:

\frac{2x^{\frac{7}{2}}}{7}+4x+c

Step-by-step explanation:

We are asked to find the value of the indefinite integral \int \:x^2\sqrt{x}+4\:dx.

Let us solve our given problem applying sum rule as:

\int \:x^2\sqrt{x}\:dx+\int \:4\:dx

\int \:x^2*x^{\frac{1}{2}}\:dx+\int \:4\:dx

\int \:x^{\frac{4}{2}}*x^{\frac{1}{2}}\:dx+\int \:4\:dx

\int \:x^{\frac{5}{2}}\:dx+\int \:4\:dx

Now, we will use power rule.

=\frac{x^{\frac{5}{2}+1}}{\frac{5}{2}+1}}+4x+c

=\frac{x^{\frac{7}{2}}}{\frac{7}{2}}+4x+c

=\frac{2x^{\frac{7}{2}}}{7}+4x+c

Therefore, our required integral would be \frac{2x^{\frac{7}{2}}}{7}+4x+c.

:( CAN SOMEONE PLEASE HELP ME
Alla [95]

Answer:

I think that Nick is correct because you are going to have to make your answer positive and when you do the two fractions -4/9 + -6/9 are going to be   6/9 + 4/9 and there is already a addition sign in the last problem we are just going to keep it there. And when we add we get 10/9 or 1 1/9

If i get it wrong please don't hate im just in 7 grade ok :(
