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.

Let f (x)=x-2 and g(x)=x to the second power -7x-9.find f (g(-1))

Degger [83]

f(g(-1)) = - 3

Evaluate g(-1) and substitute into f(x)

g(-1) = (-1)² -7(-1) - 9 = 1 + 7 - 9 = - 1

f(g(-1)) = (-1) - 2 = - 3

I need algebra help.....

Lubov Fominskaja [6]

Answer:

$y=4(3)^x$

Step-by-step explanation:

From the table given in the question,

x y Difference Ratio

1 12 - -

2 36 36-12 = 24 $\frac{36}{12}=3$

3 108 108-36 = 72 $\frac{108}{36}=3$

4 324 324-108 = 216 $\frac{324}{108}=3$

5 972 972-324 = 648 $\frac{648}{216}=3$

There is a common ratio of 3 in each successive term.

Therefore, data given in the table will represent an exponential function.

$y=a(b)^x$

For a point $(1, 12),$

$12=a(b)^1$

$ab=12$ ------(1)

For another point of the table $(2,36)$ ,

$36=a(b)^2$

$ab^2=36$ --------(2)

Equation (2) divided by equation (1)

$\frac{ab^2}{ab}=\frac{36}{12}$

$b=3$

From equation (1),

$3a=12$

$a=4$

Therefore, exponential function will be,

$y=4(3)^x$

"If three angles and two sides of two triangles are congruent, are the triangles congruent? Why or why not?"

Anettt [7]

Answer:

yes

Step-by-step explanation:

because the corresponding angles are congruent, the triangles are congruent through CPCTC. If two sides are congruent and an included angle, then the triangles are congruent through the SAS postulate. And if two sides and a non-included angle are congruent then the triangles are congruent through the AAS postulate. Any way of looking at this proves congruency through various postulates, therefore the trianlges are congruent.
