Answer:

domain is set of all real number except 4/5

Step-by-step explanation:

f(x)= (x-3)/(x)

g(x)=5x-4

Now we find (fºg)(x)

(fºg)(x)=f(g(x))

We plug in g(x) inside in f(x)

f(g(x))=f(5x-4)= ((5x-4)-3)/(5x-4)

Now simplify the numerator

f(g(x))=((5x-4)-3)/(5x-4)=(5x-7)/(5x-4)

To find out domain we set the denominator =0 and solve for x

5x-4=0

Add 4 on both sides

5x=4

Divide both sides by 5

x=(4)/(5)

So domain is set of all real number except 4/5

Determine the measure of an interior angle of the named regular polygon. If a side of the polygon is extended, determine the supplemntsry angle of an interior angle. A) the measure of each interior angle of a regular hexagon is

B) the measure of the supplementary angle of an interior angle is

Answers

Answer:

A) Each interior angle of the Regular Hexagon = 120°

B)The measure of the supplementary angle of an interior angle is  60°

Step-by-step explanation:

Regular Hexagon : A 6 sided polygon which has all 6 interior angles as  EQUAL is called a regular hexagon.

So, here are 6 interior angles of the hexagon are equal.

Also, Sum of all interior angles of an hexagon = 720°

Let us assume the each angle of the hexagon = m

⇒ m + m + m + m + m  + m = 720°

or, 6 m = 720°

or, m = 720° / 6 = 120°

⇒ Each interior angle of the Regular Hexagon = 120°

Now, a side is extended to form an exterior angle.

Let us assume the measure of that exterior angle  = k

⇒ k + m = 180 °   ( as k and m are SUPPLEMENTARY ANGLES)

or,  k = 180 - 120   = 60 °

or, k = 60 °

Hence,  the measure of the supplementary angle of an interior angle is  60°

On Saturday Jesse plays basketball for 2/3 hour Then he plays some more he plays 2 1/3 hours in all how much longer did Jesse play basketball

Answers

2 and 1/3 hours converted to a fraction is 7/3 hours. 7/3 - 2/3 = 5/3. Jesse played for 5/3 more hours, or 1 and 2/3 hours. (that would be 1 hour and 40 minutes)
Saturday =2/3
More=2 1/3
2 1/3=7/3 improper
7/3 - 2/3=5/3 or 1 2/3 hrs or 1 hr and 40 min
