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.

If 180°<θ<270°, and sin⁡θ=−3/4, what is the value of sin(−θ)?

Oxana [17]

Answer:

$sin(-\theta)=\frac{3}{4}$

Step-by-step explanation:

Given:

180°<θ<270° and $sin(\theta)=-\frac{3}{4}$

We know for any angle $\theta$ ,

$sin(-\theta)=-sin(\theta)$

∴ $sin(-\theta)=-(-\frac{3}{4})=\frac{3}{4}$

In the freshman class, 62% of the students take math, 49% take science, and 38% take both science and math. what percentage take

antoniya [11.8K]

we are given

62% of the students take math

so,

$n(M)=62$

49% take science

$n(S)=49$

38% take both science and math

n(M∩S)=38

now, we can use union formula

n(M∪S)=n(M)+n(S) -n(M∩S)

now, we can plug values

and we get

n(M∪S)=62+49 -38

n(M∪S)=73

so,

the percentage takes at least one science or math course is 73%..........Answer

my hw write find an equation of the line passing through (-2,3) and (4,-5) I have to write the equation in slope-intercept form

Viefleur [7K]

Answer:

The line passing through the given points is:

$y=-\frac{4}{3}x+\frac{1}{3}$

in its slope-intercept form

Step-by-step explanation:

Start by finding the slope of the segment that joins the two given points using the slope formula:

$slope=\frac{y_2-y_1}{x_2-x_1}$

which for our case renders:

$slope=\frac{3-(-5)}{-2-4}=\frac{8}{-6} =-\frac{4}{3}$

Now we can find the y-intercept by using any one of the given points in the general slope-intercept form of a line with this slope:

$y=-\frac{4}{3} x+b\\3=-\frac{4}{3} (-2)+b\\3=\frac{8}{3}+b\\b=3-\frac{8}{3} \\b=\frac{9-8}{3} \\b=\frac{1}{3}$

Therefore, the equation of the line becomes:

$y=-\frac{4}{3}x+\frac{1}{3}$
