Explain why statement 3^(-2)=-6 is false

Mathematics
1 answer:
malfutka [58]2 years ago

Answer: -9

Step-by-step explanation: You are not doing 3(-2) to get -6. That's incorrect. What you are supposed to do is multiply the base which is 3 and then multiply it with -2 so that would 3(3) twice and don't forget the negative in front of the two so that would be -9 as the correct answer. :)

Write a function t(I) that determines the number of
forsale [732]

Using the table, we will see that the function is:

t(l) = 3*l

<h3>How to write the function?</h3>

Here we only have a table to work with, so we need to use that.

In the table, we can see the pairs:

  • t(1) = 3
  • t(2) = 6
  • t(3) = 9
  • t(4) = 12

So, in each new level, we just add 3 more toothpicks. Even more, we can see that the number of toothpicks is 3 times the value of l (the level) for all the cases in the table. So this is a linear function.

From that we can conclude that the function will be:

t(l) = 3*l

For each trip, a taxi company charges a fixed fee of $2.00 plus $0.75 for each 1/2 mile or fraction of 1/2 miles. If, for every
nydimaria [60]

Answer:

E: 2.00 + 0.75 [ 2r]

Step-by-step explanation:

r represents the number of miles. For each 1/2 mile the taxi will charge and extra free of $0.75. Then, for each mile, the taxi will charge $0.75*2. For example:

For a trip of 1 mile the taxi will charge:

$2.00+$0.75*2

For a trip of 2 miles, the taxi will charge:

$2.00+0.75*4

For a trip of 10 miles, the taxi will charge:

$2.00+$0.75*20

Notice that the variable fee (the one that depends on the number of miles) is $0.75 times the double of miles. In each case the number of miles is multiplied by two. Then the correct answer is E: 2.00 + 0.75 [ 2r]
