If m(x)= x+5/x-1 and n(x)=x-3, which function has the same domain as (m*n)(x)?

Answers

Answer 1
Answer:

Using the domain concept, it is found that f(x) = (1)/(x - 3) has the same domain as (m * n)(x) = (x^2 + 4x - 5)/(x - 3)

------------------------

  • The domain of a function is given by all possible values of the input.
  • The functions are:

m(x) = (x + 5)/(x - 1)

n(x) = x - 3

  • Their multiplication is given by:

(m * n)(x) = (x + 5)/(x - 1) * x - 3 = ((x + 5)(x - 1))/(x - 3) = (x^2 + 4x - 5)/(x - 3)

  • In a fraction, the denominator cannot be 0, thus, the domain is all real numbers except 3. A function with the same domain is one in which the numerator is changed while the denominator is the same, for example, f(x) = (1)/(x - 3)

A road crew must repave a road that is 3/5 miles long. They can repave 1/15 miles each hour. How long will it take the crew to repave the road?

Answers

The Total number of hours required to repave the whole road is 36.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

The Total length of the road that needs to be repaved =  3/5 miles

The Total length of the road which is repaved by the road crew per hour = 3/5  miles

The Total number of hours required to repave the whole road

= (Length of the road  to be repaved)/(Length of the road repaved by the crew per hour)

= 3/4 divided by 1/48

= 3/4*48/1= 144/4

= 36

Hence, The Total number of hours required to repave the whole road is 36.

Mom buys a rectangular rug with an area of 7 1/6 square meters. The length of the rug is 3 1/3 meters. What is the width of the rug?

Answers

Answer:

  • 2 3/20 m

Step-by-step explanation:

The area is the product of the length and width

  • The area = 7 1/6 m² = 43/6 m²
  • The length = 3 1/3 m = 10/3 m

Width = ?

  • A = lw
  • w = A/l
  • w = 43/6 ÷ 10/3 = 43/6 × 3/10 = 43/20 = 2 3/20 m

The width is 2 3/20 m
