What is the value of the geometric sequence for which a1=10 and r=0.5?

Mathematics

The formula for an infinite geometric sequence is the following:

S_{∞}= \frac{a_{1}}{1-r}

Just substitute the values of a_{1} and r into the formula.

S_{∞}=\frac{10}{1-0.5}
S_{∞}=\frac{10}{0.5}
S_{∞}= 20

Therefore, the answer is 20.

Analysis and observations in these two graphs
professor190 [17]

By critically observing the graph, we can infer and logically deduce the following points:

  • The linear function is given by y = 0.0169x + 32.485.
  • The initial temperature for both data is greater than 32°C.
  • The final temperature for both data is less than 33.5°C.
  • Between 1980 and 2020, the temperature for graph 2 (thick-continuous line)  was constant.
  • Graph 1 (thin-dashed line) is essentially a linear graph.

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

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.

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

A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.

This ultimately implies that, the data of a linear graph are directly proportional and as such, as the value on the x-axis increases or decreases, the values on the y-axis also increases or decreases.

By critically observing the graph which models the changes in temperature over a specific period of time (in years), we can infer and logically deduce the following points:

  • The linear function is given by y = 0.0169x + 32.485.
  • The initial temperature for both data is greater than 32°C.
  • The final temperature for both data is less than 33.5°C.
  • Between 1980 and 2020, the temperature for graph 2 (thick-continuous line)  was constant.
  • Graph 1 (thin-dashed line) is essentially a linear graph.

In conclusion, there are four (4) points of intersection on this graph.

zysi [14]

Answer:

Number of student bring their lunch = 60

Step-by-step explanation:

Given:

Total number of student = 600

Student bring their lunch = 10%

Find:

Number of student bring their lunch

Computation:

Number of student bring their lunch = Total number of student x Student bring their lunch

Number of student bring their lunch = 600 x 10%

Number of student bring their lunch = 60
