Answer:

\frac{1}{(m-3)(m-4)}

Step-by-step explanation:

(m+3/m^2-16)/(m^2-9/m+4)

Lets factor the numerator and denominator

use identity a^2 - b^2 = (a+b)(a-b)

m^2 - 16= m^2 - 4^2 = (m+4)(m-4)

m^2 - 9= m^2 - 3^2 = (m+3)(m-3)

we have divisiion sign in  between, change the division symbol in to multiplication symbol by flipping the fraction in the denominator

(m+3/m^2-16)*(m+4/m^2-9)

\frac{m+3}{(m+4)(m-4)} * \frac{m+4}{(m+3)(m-3)}

Cancel put m+3  and m+4  at the top and botom

\frac{1}{(m-3)(m-4)}

Describe in words the region of R3 reperesented by the equations or inequalities y2+z2=16
Anastasy [175]

Answer:

It represents an infinite cylinder of radius 4.

Step-by-step explanation:

The first thing to notice is that

y^2+z^2=4^2

<u>represents a circle of radius 4</u>, with its center in the origin of a plane yz, of cartesians coordinates.

Starting from here, we have to put the coordinate x, for all values of x, to complete the space R³. <em>This will enlarge this circle we had on the plane, to infinity</em> (positive and negative on the x-axis).

Finally, we have that this region is a cylinder of radius 4, with center in y=0 and z=0, and of infinite length in the x coordinates.

Hitman42 [59]

Answer:

Each hour he fly 107.76 miles

Step-by-step explanation:

we know that

Charles Lindbergh flew 3,610 miles in 33.5 hours

To find out the unit rate, divide the total distance by the total time

so

\frac{3,610}{33.5}= 107.76\frac{miles}{hour}

therefore

Each hour he fly 107.76 miles
