A scientist is investigating the effects of salinity on fish development in the Atlantic Ocean. He places fertilized fish eggs i

n an aquarium that contains lower salinity than typical Atlantic Ocean water. He observes that the fertilized eggs fail to develop. He concludes that fish eggs do not develop in conditions with low salinity. Why is this an invalid conclusion? The experiment lacks an experimental group. The experiment does not measure any dependent variables. The experiment does not have a group tested in normal salinity. The experiment changes more than one variable at once. i need help ASAP PLEASE

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.

The sum of two numbers is 32. Five times the smaller number minus twice the larger number is 195.What are the numbers ?
Harlamova29_29 [7]

Answer:

  • 37 and -5

Step-by-step explanation:

Le the numbers be x and y

<u>Then we have equations:</u>

  • x + y = 32
  • 5x - 2y = 195

<u>As per the first equation:</u>

  • y = 32- x

<u>Substitute in the second equation</u>

  • 5x - 2(32 - x) = 195
  • 5x + 2x - 64 = 195
  • 7x = 195 + 64
  • 7x = 259
  • x = 259/7
  • x = 37

<u>Then finding the value of y</u>

  • y = 23 - 37 = -5
