Graph of a Function

Given a real function f(x), we can construct its graph by taking random values for x, computing f(x) for each selected value, and plotting the pairs (x,f(x)) in a rectangular grid. By joining the points we get an approximate graph.

It's not always easy to find an appropriate set of values for x which makes the important part of the graph be clearly shown in the graph. We select the range for x between -30 and +70. The results are shown in the table below.

The graph is also shown in the second image provided.

Belinda finds a CD with 2.8% APR compounded annually. How much money will Belinda invest in this CD if she wants to have a yearl

Valentin [98]

Belinda will need to use the simple compounding formula to get the yearly income of $3500.
Present amount = Future amount /(1+interest)^payments
where
Future amount = $35000
interest = 2.8%
payments = 1
Subsitute all the given values, we will get the present amount
Present amount of CD = $34,046.7

On the first math test, Keiko answered 19 out of 25 questions correctly. On the

m_a_m_a [10]

Answer:

Keiko got a better answer on the test on her second test, and you could compare these two ratios as they are written.

Step-by-step explanation:

First: Convert each of the scores into percentages:

How do you convert ratios to percentages? Well, first we have to convert the ratio to a decimal or a fraction. Let's convert it to a fraction. So, 19 out of 25 will become $\frac{19}{25}$ , and 17 out of 20 will become $\frac{17}{20}$ . To convert a fraction to a percentage:

Divide the numerator by the denominator:

19 ÷ 25 = 0.76 AND 17 ÷ 20 = 0.85

Multiply your quotient by 100

0.76 x 100 = 76 AND 0.85 x 100 = 85

Add the percent sign

76% AND 85%

Now the two quantities are easier to compare. We can obviously see that 85% is bigger [and better] than 76%. So, the ratio that equals 85% - 17 out of 20 - is a better grade.

The second question was: Can you compare these two ratios as they are written? Explain why or why not.

Yes, you can compare these two ratios, just find the [positive] difference between the amount that she scored and the total number of scores that could be gained.

25 - 19 = 6

20 - 17 = 3

Since the equation with 20 and 17 in it has a smaller difference, it is most likely to have a greater value [because that means that Keiko got more right and less wrong, which means a greater mark which is also a greater quantity].

Thanks,
