Yes, histograms main purpose to show ranges from a graph. so like lets say you have a problem where you have ranges of different ages like people from 20-29, 30-45, 46-65, 66-85, you would put that on the y axis and the amount of people on the x axis

Rewrite in the form . Then find q(x) and r(x).
gizmo_the_mogwai [7]

Answer:

q(x)= 2x+5

r(x)=6

b(x)=x+4

Step-by-step explanation:

I have found what is missing in your question: Rewrite 2x^2+13x+26/x+4 in the form q(x)+r(x)/b(x).

First, we have to divide the polynomial  by x+4 and remember that is x times 2x.

By multiplying this we are going to get 2x^{2} + 8x and now we are doing separation of it and getting 2x^{2}  + 13x + 26 and getting 2x^{2}  + 13x + 26/ x + 4 = 2x^{2} +8x/x+4=5x+26/x+4=2x + 5x+26/x+4

Because 5 is showing x times 5 we are going to multiply (x + 4) with 5 and that is 5x + 20.

5x+26/x+4 = 5x + 20/x+4 = 6/ x+4=5 + 6/x+4

Now when we can get more simplified we are having:

2x^{2} +13+26/x+4=2x + 5= 6/x+4

If sin theta = 4/5 and theta is in quadrant 2, the value of cot theta is
trasher [3.6K]

Answer:

Cot(theta) = - 0.75 or -3/4

Step-by-step explanation:

The hypotenuse is 5

The y value is 4

We need to find the corresponding x value.

x^2 + y^2 = z^2

X = ?

y = 4

z = 5

x^2 + 4^2 = 5^2

x^2 + 16 = 25

x^2 = 9

Now in this case, you are in quadrant 2, so the x value is - 3

sqrt(x^2) = sqrt(9)

x = - 3

The cot value is the adjacent (x value) / the opposite ( y ) value

Cot(theta) = -3/4

cot(theta) = -0.75
