Answer:

The 4th term of the sequence is 9.

The domain of the sequence is all natural numbers.

(4, 9) lies on the graph of the sequenced

Step-by-step explanation:

sequence –3, 5, –7, 9, –11......

First term is -3, second term is 5, third term is -7 , fourth term is 9 and fifth term is -11

So we are given with 5 terms in the sequence but the sequence continues . It does not stop with 5 terms.

fourth term is 9.The 4th term of the sequence is 9.

Natural numbers are the positive integers . Domain is the input of the sequence. Input is the number of terms. So domain is all natural numbers.

Fourth term of the sequence is 9 . So (4,9) lies on the graph.

I need answers and explanation with ratios to help my daughter with homework
Leviafan [203]

Using proportions, it is found that:

2. Bree types at a faster rate, as her ratio of 1.13 words per second is greater than Alan's rate of 0.83 words per second.

3. Bree also makes mistakes at a raster rate, as her rate of 0.375 mistakes per second is greater than Alan's rate of 0.33 mistakes per second.

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

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

For each of Alan and Bree, we have to find the proportions of words typed per second and mistakes per second.

Then, for Alan:

  • Words typed per second: 5/6 = 0.83.
  • Mistakes per second: 2/6 = 0.33.

For Bree:

  • Words typed per second: 9/8 = 1.13.
  • Mistakes per second: 3/8 = 0.375.


Then:

2. Bree types at a faster rate, as her ratio of 1.13 words per second is greater than Alan's rate of 0.83 words per second.

3. Bree also makes mistakes at a raster rate, as her rate of 0.375 mistakes per second is greater than Alan's rate of 0.33 mistakes per second.
