Why is y=cosx a polynomial function

1 answer:

5 0

The graph of the cosine function: A function f is said to be odd, provided that f(–x) = –f(x), for all x. Such functions have graphs that are symmetric about the origin: Also any function with a graph symmetric about the origin is an odd function. hope that helped.

Answer:

ST=26

Step-by-step explanation:

RS+ST=RT

17+x+16=4x+3

x+33=4x+3

33-3=4x=x

3x=30

x=30/3

x=10

ST=x+16

ST=10+16

ST=26

A survey handed out to individuals at a major shopping mall in a small Florida city in July asked the following: Gender Age Ethn

AysviL [449]

Answer and Explanation:

Gender data is categorical as it can be sorted into two categories - males and females - and does not involve any numerical values.

Age data is ratio as each person's age is a numerical value and it has a natural zero as point of origin. Moreover, the numerical values cannot be negative.

Ethnicity data is categorical as the various ethnicities to which those surveyed can belong are separate categories. There are no numerical values involved.

Length of residency data is ratio as the length duration is measured in number of years, thus having a numerical value. There is also a natural zero as point of origin and no possible negative values.

Overall satisfaction with city services data is ordinal as it is based on a ranking from poor to excellent.

Quality of schools data is also ordinal as it involves a ranking or definite ordering of data - from poor to excellent.

Use the T-table below to determine 3 solutions to this equation: y = 2x

Jet001 [13]

The table is attached as a figure

The given equation is ⇒⇒⇒⇒ y = 2x
To solve this equation, we need to pick numbers from the table then this number will be substituted into the equation to find y
we need 3 solutions . so, we need to pick 3 numbers of x
From the table, let us choose x = 0
y = 2x
y = 2 * (0)
y = 0

From the table, let choose second value of x such as x = 1
y = 2 * (1)
y = 2

From the table, let choose third value of x such as x = -1
y = 2 * (-1)
y = -2

So, the picked three solutions are
y = 0 at x = 0
y = -2 at x = -1
y = 2 at x = 1
