Answer:

D = 13 units

Step-by-step explanation:

<u><em>Using Distance Formula to find the length.</em></u>

Distance Formula = \sqrt{(x2-x1)^2+(y2-y1)^2}

D = \sqrt{(2+3)^2+(-5-7)^2}

D = \sqrt{(5)^2+(-12)^2}

D = \sqrt{25+144}

D = \sqrt{169}

D = 13 units

Describe the graph of the function f(x) = x3 − 11x2 + 36x − 36. Include the y-intercept, x-intercepts, and the shape of the grap
kap26 [50]
1) y-intercept => x = 0, => y = f(0) = 0 - 0 + 0 - 36 = -36

2) x-intercept => y = 0 => factor the function (start by dividing by x -2)

f(x) = (x-2)(x-3)(x-6) =0 => x =2, x = 3, x = 6 (these are the x-intercepts)

3) critical points:

between x = 2 and x = 3, there is a local maximum

between x =3 and x = 6 there is a local minimum

3) Shape.

The function comes growing from - infinity.

In the third quadrant the function is negative (it does not pass throuhg the second quadrant)

It enters to the fourth quadrant intercepting the y-axis at y = -36. It continues growing and intercepts the x-axis at x = 2.

 It continues increasing until a maximum local positive value, starts to decrease, intercepts the x-axis at x = 3, continues decreasing, becomes negative, gets a local minimum in the fourth quadrant, starts to increase, intercepts the x-axis at x = 6, becomes positive, and continues growing.

3. What is the slope of the line passing through (15,-5) and (3, -8)?
Andrej [43]
M= -8 - -5/ 3 - 15= -8+5/3-15= -3/-12 = 3/12 = 1/4 


The slope is 1/4. 
The slope formula is m=y2-y1/x2-x1. I plugged in -8=y2, -5=y1, 3=x2, and 15=x1. Then I solved it.

-8=-(x+4) i need help with this problem!!
kozerog [31]

X=4

You have to distribute the negative sign for everything in the parentheses. After that you add x to the other side then add 8 to the opposite side to move them. Then your answer is 4.
