What is the symbol of an inverse function

Nataly_w [17]

Answer:

f(-1

Step-by-step explanation:

The inverse of the function f is denoted by f -1 (if your browser doesn't support superscripts, that is looks like f with an exponent of -1) and is pronounced "f inverse".

The following graph represents the cost of a phone plan after a certain number of text messages used in a month. Analyze the gra

inysia [295]

Here we want to analyze the given graph.

The answers are:

a) for 500 messages the cost is $30 and for 1800 messages the cost is $80.

b) It means that for 1400 messages the cost is $60.

c) Because there is a fixed cost for the first 800 messages.

Let's expand more on each solution.

First, remember that the horizontal axis represents the number of text messages end in hundreds, while the vertical axis represents the cost in dollars.

a) We want to find the cost for 500 texts and 1800 texts.

To find the cost for 500 texts, you need to count 5 squares on the horizontal axis, and then see where the graph intersects the vertical axis for that value.

We can see that:

f(500) = $30

We do the same for 1800 (this time you count 18 squares), then we get:

f(1800) = $80

b) f(1400) = 60

This would mean that the cost of 1400 text messages is 60 dollars.

c) Assume that for the first 800 text messages you have a fixed cost, and after that the company starts to charge an extra for each message you send, this is why we would have a linear increase after the message number 800.

An object in a simulation accelerates

notsponge [240]

Observe the graph below. This graph represents the scenario.

The question is ill formated, the complete question is

In a simulation, a moving object accelerates from rest to 4 meters per second in 2 seconds. For the following three seconds, it increases linearly until it reaches a speed of 10 meters per second. Following three seconds at that speed (acceleration = 0), the item progressively decelerates until it comes to rest two seconds later. Draw the graph of this scenario for 10 seconds?

I'll describe how the graph may show.

It will move diagonally upward from time 0 to 2 seconds until it reaches the y axis at a speed of 4 m/s.

Then, from 2 to 5, the position will move up diagonally until it reaches the y axis at a speed of 10 m/s.

The next 5 to 8 seconds will be horizontal.

After that, it will descend diagonally.

Observe the graph below. This graph represents the scenario.

What is 4.24 x 10^2 in standard form ( scientific notation)

TiliK225 [7]

Answer:

424

Step-by-step explanation:

10 to the second power is 10x10. that gives you 100

multiply 4.24 by 100

you get 424

4.24 (10x10)

4.24x100=424
