Answer:

D' = (2, -3)

E' = (2, -1)

A' = (5, -3)

Step-by-step explanation:

Coordinates are :

D = (-4, -4)
E = (-4, -2)
A = (-1, -4)

The transformation rule is :

(x , y) ⇒ (x + 6, y + 1)

Point D'

D' = (-4 + 6, -4 + 1)
D' = (2, -3)

Point E'

E' = (-4 + 6, -2 + 1)
E' = (2, -1)

Point A'

A' = (-1 + 6, -4 + 1)
A' = (5, -3)

A salesperson's weekly paycheck is 40% more than a second salesperson's paycheck. The two paychecks total $1075. Find the amount

BlackZzzverrR [31]

X is gonna be the normal paycheck

0.45x+x=1075

= 0.40x+x=1075

= 1.4x=1075

x= 1075/1.4

x=767.85 the normal paycheck price

1075.00-767.85= 307.15

so a saleperson weekly paycheck is 307.15 dollars more

hope this helps

Q1. Find y, if √12 - √147 + y√3 = 0

o-na [289]

Answer:

Q1. y = 5 Q2. (√2 - √3)/2

Step-by-step explanation:

√12 - √147 + y√3 = 0

Taking -√147 and √12 to the right hand side, we have

y√3 = √147 - √12

y√3 = √(3 × 49) - √(3 × 4)

y√3 = √3 × √49 - √3 × √4

y√3 = √3 × 7 - √3 × 2

y√3 = 7√3 - 2√3

y√3 = 5√3

Dividing both sides by √3, we have

y√3/√3 = 5√3/√3

y = 5

Sin45° - Cos30°

Since Sin45° = √2/2 and Cos 30° = √3/2

Substituting these values into the equation, we have

Sin45° - Cos30° = √2/2 - √3/2

Taking L.C.M of both factors, we have

Sin45° - Cos30° = (√2 - √3)/2

Assoli18 [71]

Answer:

Explanation:

1) Principal quantum number, n = 2

n is the principal quantum number and indicates the main energy level.

2) Second quantum number, ℓ

The second quantum number, ℓ, is named, Azimuthal quantum number.

The possible values of ℓ are from 0 to n - 1.

Hence, since n = 2, there are two possible values for ℓ: 0, and 1.

This gives you two shapes for the orbitals: 0 corresponds to "s" orbitals, and 1 corresponds to "p" orbitals.

3) Third quantum number, mℓ

The third quantum number, mℓ, is named magnetic quantum number.

The possible values for mℓ are from - ℓ to + ℓ.

Hence, the poosible values for mℓ when n = 2 are:

for ℓ = 0: mℓ = 0

for ℓ = 1, mℓ = -1, 0, or +1.

4) Fourth quantum number, ms.

This is the spin number and it can be either +1/2 or -1/2.

Therfore the full set of possible states (different quantum number for a given atom) for n = 2 is:

(2, 0, 0 +1/2)
(2, 0, 0, -1/2)
(2, 1, - 1, + 1/2)
(2, 1, -1, -1/2)
(2, 1, 0, +1/2)
(2, 1, 0, -1/2)
(2, 1, 1, +1/2)
(2, 1, 1, -1/2)

That is a total of 8 different possible states, which is the answer for the question.
