k^2 = 4k

k = 0, k = 4

k^2 - 5k = k + 7

k^2 - 6k = 7

k^2 - 6k + 9 = 16

k - 3 = 4 ⇒ k = 7

k - 3 = -4 ⇒ k = -1

k^3 - 5k^2 + 3k = -k

k^3 - 5k^2 + 4k = 0

k(k^2 - 5k + 4) = 0

k = 0, k = 1, k = 4

|k + 1| + 2 = 8

|k + 1| = 6

k = 5, k = -7

Answer:

Interquartile Range = 34

Range = 55

Step-by-step explanation:

Max - Min = Range

75 - 20 = 55

Quartile 3 - Quartile 1 = IQR

68 - 34 = 34

Solve for B - PLEASE HELP IMMA DIE

Marta_Voda [28]

First, you would have to add d to both sides to get rid of it
x+d=ab+c/b
Then you would multiply b by both sides to get rid of the b in the denominator
x+d(b)=ab+c
After that, you would subtract c from both sides
x+d(b)-c=ab
Then you would divide both sides by a
x+d(b)-c=b
------------

What are the intercepts of the line 2x + 4y = 12?

Darina [25.2K]

<span>if you're finding the x intercept, y is ALWAYS 0, so in this, you can just get rid of the -4y because you know that it's 0, so you're left with 2x=12 divide by 2 on both sides so you find x intercept is (6,0) on the graph
the y works the same way, if you're looking for the y, you know that the x is zero, so you're left with -4y=12, divide by -4y on both sides and you end up with the y intercept being (0,-3)

x int.= (6,0)
y int.= (0,-3)

by the way, when it's written like that, it's called standard form, so to find the intercepts on 2x=12+4y, you'd have to convert it into standard form (Ax=By=C) so you subtract 4y on both sides to make it 2x-4y=12, and then once you have it like that you can do the math to find the y and x intercepts.

a student walks 50m on a bearing 0.25 degrees and then 200m due east how far is she from her starting point.

Inessa05 [86]

Answer:

Step-by-step explanation:

I'm going to use Physics here for this concept of vectors. Here are some stipulations I have set for the problem (aka rules I set and then followed throughout the problem):

** I am counting the 50 m as 2 significant digits even though it is only 1, and I am counting 200 as 3 significant digits even though it is only 1. 1 sig dig doesn't really give us enough accuracy, in my opinion.

** A bearing of .25 degrees is measured from the North and goes clockwise; that means that measured from the x axis, the angle is 89.75 degrees. This is the angle that is used in place of the bearing of .25 degrees.

** Due east has an angle measure of 0 degrees

Now let's begin.

We need to find the x and y components of both of these vectors. I am going to call the first vector A and the second B, while the resultant vector will be C. Starting with the x components of A and B:

$A_x=50cos(89.75)$ so
