Answer:

42

Step-by-step explanation:

180- half of 42

138= x+ measure of 9

so means

10+6=16means other side is also 16

7=y+x

an arc is half the inner measure

so really 84-42

42

hope this helps

HELP PLS Match each graph with the logarithmic function it represents
SIZIF [17.4K]

Each graph has been matched with the logarithmic function it represents as follows:

  • f(x) = 3 - 4In (x-2) = graph 3.
  • f(x) = 3 - Inx = graph 1.
  • f(x) = In(x + 1) = graph 4.
  • f(x) = 2In(x + 3) = graph 2.

<h3>What is a function?</h3>

A function can be defined as a mathematical expression which is used to define and represent the relationship that exists between two or more variables.

<h3>The types of function.</h3>

In Mathematics, there are different types of functions and these include the following;

  • Periodic function
  • Inverse function
  • Modulus function
  • Signum function
  • Piece-wise defined function.
  • Logarithm function

<h3>What is a logarithm function?</h3>

A logarithm function can be defined as a type of function that represents the inverse of an exponential function. Mathematically, a logarithm function is written as follows:

y = logₐₓ

In this exercise, you're required to match each graph with the logarithmic function it represents as shown in the image attached below:

  • f(x) = 3 - 4In (x-2) = graph 3.
  • f(x) = 3 - Inx = graph 1.
  • f(x) = In(x + 1) = graph 4.
  • f(x) = 2In(x + 3) = graph 2.

Simora [160]

The question is incomplete. Here is the complete question

It was estimated that because of people switching to Metro trains about 33000 of CNG 3300 tons of diesel and 21000 tons of petrol was saved by the end of year 2007 (I) find a fraction of the quantity of diesel saved to the quantity of petrol saved (ii) find the quantity of cng to the quantity of diesel saved

Answer:

(I) 11/70

(II) 1/10

Step-by-step explanation:

Metro trains contain 330,000 tons of CNG

3300 tons of diesel was saved

21000 tons of petrol was saved at the end of 2007

(I) The fraction of the quantity of diesel saved to the quantity of petrol saved can be calculated as follows

= 3300/21000

= 11/70

(II) The fraction of the quantity of CNG saved to the quantity of diesel can be calculated as follows

= 3300/33000

= 1/10
