we know that

A mapping diagram shows how the elements are paired. Its like a flow chart for a function, showing the input and output values.

The input values are the elements of the domain and the output values are the elements of the range.

In this problem

Input Values (Domain) are

[-2, 0, 1,5]

Output Values (Range) are

[-6, 3,-5,0]

therefore

the answer is

The correct answer is the second diagram

see the attached figure

The correct answer is the second diagram.

In a mapping diagram, the x values are on the left and the y values are on the right. The arrows should point from the x value to its corresponding y value.

Hope this helps!

Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form. 125, 25
Igoryamba

Answer:

Given sequence is an arithmetic sequence.

Step-by-step explanation:

Given sequence is:

125, 25, 5, .. ..​

Here

a_1 = 125\\a_2 = 25\\a_3 = 5

  • A sequence is geometric sequence when the common ratio of consecutive terms is same. It is denoted by r.
  • A sequence is an arithmetic sequence when the common difference of consecutive terms is same. It is denoted by d.

Finding the common ratio

r = \frac{a_2}{a_1} = \frac{125}{25} = 5\\r = \frac{a_3}{a_2} = \frac{25}{5} = 5

As we can see that the common ratio is same, the given sequence is a geometric sequence.

LAST ONE GUYSSS \small \angle L and \small \angle M are supplementary, \small m\angle L=12x+45 and \small m\angle M=18x-30. Dete
svp [43]

Answer:

m\angle L = 111\degree \\m\angle M = 69\degree

Step-by-step explanation:

Since, angle L and angle M are supplementary.

\therefore m\angle L + m\angle M= 180\degree  \\ \therefore \: 12x + 45 + 18x - 30 = 180 \degree \\ \therefore \: 30x + 15= 180 \degree\\ \therefore \: 30x= 180 \degree - 15 \degree\\ \therefore \: 30x= 165 \degree  \\ x =  \frac{165 \degree}{30}  \\ x = 5.5 \degree \\  \\ m\angle L  = 12x + 45  \\ m\angle L = 12 \times 5.5 + 45 \\ m\angle L  = 66 + 45 \\ \huge \red{ \boxed{ m\angle L  = 111 \degree}} \\  \\ m\angle M=18x - 30 \\ m\angle M=18 \times 5.5 - 30 \\ m\angle M=99 - 30 \\ \huge \purple{ \boxed{ m\angle M=69 \degree}} \\

What is the resistance of a 3.1 m length of copper wire 1.7 mm in diameter?
Bumek [7]
R = ?
L = 3.1 m;
r = 1.7 mm/ 2 = 0.85 mm = 0.85 * 10^(-3) m
Resistivity of copper ( rho ) = 1.68 * 10 ^(-8) [Ohm m ]
A = 3.15 * ( 0.85 * 10^(-3))^2 = 2.26865 * 10 ^(-6)
R = ( Rho ) * L / A = 1.68 * 10^(-8) * 3.1 m / 2.26865 * 10^(-6) =
= (1.7 * 3 .1 / 2.26865 )* 10^(-2) = 0.02323 Ohms ( the resistance )
