Which of the following represents the graph of f(x) = one−half to the power of x?
puteri [66]

f(x) = \frac{1}{2}^x

In this exponential function , the base is \frac{1}{2}

if base is less than 1 then it a decreasing function

We can verify it using a table

We plug in some x and values and find out f(x) to get point for the graph

x -----> f(x)

-1 -----> 2

0 ------> 1

1 -------> 0.5

The table is same as the points in first graph.

So first graph represents the graph of f(x) = \frac{1}{2}^x

That depends on the total distance of the race, which you
have not bothered to mention.

If the team has exactly enough runners to run the entire race,
one at a time, then the number of runners needed is ...

Jaime has 5 over 11 spaceof a project completed while Tim has finished 7 over 13 spaceof the same project.
lina2011 [118]

Tim has completed greater amount of work and overall they have completed 142/143 of the project work

Step-by-step explanation:

Given

Work completed by Jaime = j = 5/11

Work completed by Tim = t = 7/13

<u>a. Who has completed the greater amount of work?</u>

In order to see that we have to convert the fractions in decimal

So,

j = 5/11 = 0.45

t = 7/13 = 0.53

As we can see that the decimal for Tim's work space is large, Tim has completed greater amount of work

b. How much of the project have they completed together? Show your work.

We have to find the total work done by them

Total\ work = j + t\\= \frac{5}{11} + \frac{7}{13}\\=\frac{65+77}{143}\\=\frac{142}{143}

Hence,

Tim has completed greater amount of work and overall they have completed 142/143 of the project work
