Scientific notation means -- one digit before the decimal point, all the others after it; -- count jow many places you have to move the decimal point to make the number look like that; -- left is positive, right is negative; -- after the digits, write " x 10 to the power of" that number from moving the point. / / / / You're starting with 0.006468 . You want it to be 6.468 . You have yo move the decimal point 3 places to the right ... that makes the power -3 . Finally, in scientific notation, it's 6.468 x 10 to the -3 power.

Describe how to identify a trend and a relationship between sets of graphed data

Masteriza [31]

Trends are simply the patterns on a graph.

The types of trend are:

Linear trend
Nonlinear trend
Random trend

The linear trend

This is identified in any of the following ways

An increment in a variable causes an increment in the other variable
An increment in a variable causes a decrement in the other variable

Any of the two stated above represents a linear trend

Nonlinear trend

This type of trend are in form of curves

When you observe that the pattern on the graph follows a curve, then the trend is nonlinear

Random trend

This simply means no trend or scattered trend.

When there are no visible relationship between the variables of the graph, then the graph has a random trend.

See attachment for illustration of trends

Using only the values given in the table for the function f(x) = –x3 + 4x + 3, what is the largest interval of x-values where th

Bas_tet [7]

Answer:

the largest interval of x values where f(x) is increasing is (-1,1).

Step-by-step explanation:

$f(x)=-x^3+4x+3$

the domain of f(x) is all real numbers.

As we can conclude from the table that the function f(x) is decreasing from (-3, -1) and the function is increasing from (-1, 1) .

Graphically we can also show this that for the x-values in (1,-1) function is increasing.

Problem 27)

Refer to the diagram that says "problem 27".

This is the graph of y = 5x where x is the time in years, and y is the amount of simple interest in the account.

This equation comes from the simple interest formula below

i = P*r*t

i = 100*0.05*x

i = 5x

y = 5x

Note: The graph is a straight line through (0,0) and (1,5)

=====================================================

Problem 28)

The abscissa is the x coordinate. For a point like (-3, -7), the abscissa is -3.

The ordinate is the y coordinate. For that point mentioned earlier, the ordinate is -7.

The graph of points is shown below in the figure labeled "problem 28".

When graphing any point, we always start at the origin (0,0) where the x and y axis meet up. Then for a point like (-3,-7) we move 3 units to the left on the x axis and 7 units down on the y axis to arrive at point A. The other points are plotted in a similar fashion. The labels A,B,C,D are optional. They were added to help keep track of the points.
