Answer:

The principal quantum number, n, describes the energy of an electron and the most probable distance of the electron from the nucleus. In other words, it refers to the size of the orbital and the energy level an electron is placed in. The number of subshells, or l, describes the shape of the orbital.

10x-2y=18 8x=y solve by substitution

lana [24]

Answer:

x = -1 and y = 18

Step-by-step explanation:

Given the system of equations

y + 8x = 10... 1

2y - 4x = 40 ... 2

From 1; y = 10-8x

Substitute into 2;

2(10-8x) - 4x = 40

20 - 16x - 4x = 40

20 - 20x = 40

-20x = 40 - 20

-20x = 20

x = -1

Recall that y = 10-8x

y = 10 - 8(-1)

y = 10 + 8

y = 18

therefore your answer is x = -1 and y = 18

How many solutions does the equation sin(4x)= 3/4?

MAVERICK [17]

$sin(4x)= \dfrac{3}{4}$

$4x=sin^-^1( \dfrac{3}{4}), \pi -sin^-^1( \dfrac{3}{4})$

<span>Since sin is a periodic function, add the periodicity.
</span>
$4x=2\pi n+sin^-^1 ( \dfrac{3}{4} ) ,nEZ 

$

$4x=2\pi n-sin^-^1 ( \dfrac{3}{4} ) ,nEZ$

$x= \dfrac{2\pi n+sin^-^1 ( \dfrac{3}{4} ) }{4}, nEZ$

$x= \dfrac{2\pi n+ \pi -sin^-^1 ( \dfrac{3}{4} ) }{4}, nEZ$
