Find the domain and range of each relation. Then determine if the relation is a function. D={-2, -1, 3, 5}, R={-7 ,0 ,4} Functio
poizon [28]

Answer:

D = \{-2,-1,3,5\} -- Domain

R = \{-7,0,4\} -- Range

It is a function

Step-by-step explanation:

Given

D = \{-2,-1,3,5\}

R = \{-7,0,4\}

Required

State the domain and range

Determine if the relation is a function

From the question, we have the domain and range as:

D = \{-2,-1,3,5\} -- Domain

R = \{-7,0,4\} -- Range

Next, is to determine if the relation is a function or not.

Yes, it is a function.

The number of elements in the domain is 4

The number of elements in the range is 3

<em>When the domain has more elements than the range, this is called a many-to-one function, and it is a valid type of function.</em>

Ipatiy [6.2K]

Answer:

  see below

Step-by-step explanation:

Any line between two points on the circle is a chord.

Any angle with sides that are chords and with a vertex on the circle is an inscribed angle.

Any angle with sides that are radii and a vertex at the center of the circle is a central angle. Each central angle listed here should be considered a listing of two angles: the angle measured counterclockwise from the first radius and the angle measured clockwise from the first radius.

<h3>1.</h3>

chords: DE, EF

inscribed angles: DEF

central angles: DCF . . . . . note that C is always the vertex of a central angle

<h3>2.</h3>

chords: RS, RT, ST, SU

inscribed angles: SRT, RSU, RST, RTS, TSU

central angles: RCS, RCT, RCU, SCT, SCU, TCU

<h3>3.</h3>

chords: DF, DG, EF, EG

inscribed angles: FDG, FEG, DFE, DGE

central angles: none

<h3>4.</h3>

chords: AE

inscribed angles: none

central angles: ACB, ACD, ACE, BCD, BCE, DCE

Determine the mean of the numbers 6, 17, 22, 28, and 37.
Kipish [7]
To find the mean or the avg you add up all the numbers you have and then divide by how many numbers you added together in this case 5

6+ 17+22+28+37=110

\frac{110}{5} =22

so the mean is 22, hope this helped you!
