Dy/dx, ie., the difference in y divided by the difference in x. If you have two points A and B, sort them in ascending order of x.

dx = 5 - -3 = 8 (x coordinates of B minus x coordinate of A)
dy = -3 - 5 = -8 (y coordinate of B minus y coordinate of A)

dy/dx = -1

So the slope is -1. The equation of the line is y=2-x.

A half-filled cylindrical water tank has a water level of 20 feet high. The tank can hold 6000 cubic feet of water. Find the dia
Anettt [7]

Answer:

d = 13.8 feet

Step-by-step explanation:

Because we are talking about cubic feet of water, we need the formula for the VOLUME of a cylinder.  That formula is

V=\pi r^2h

We will use 3.141592654 for pi; if the tank HALF filled with water is at 20 feet, then the height of the tank is 40 feet, so h = 40; and the volume it can hold in total is 6000 cubic feet.  Filling in then gives us:

6000=(3.141592654)(r^2)(40)

Simplify on the right to get

6000=125.6637061r^2

Divide both sides by 125.6637061 to get that

r^2=47.74648294

Taking the square root of both sides gives you

r = 6.90988299

But the diameter is twice the radius, so multiply that r value by 2 to get that the diameter to the nearest tenth of a foot is 13.8

  • Distance Formula: \displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Step-by-step explanation:

<u>Step 1: Define</u>

Point (-1, -13)

Point (-1, 21)

<u>Step 2: Find distance </u><em><u>d</u></em>

  1. Substitute in points [DF]:                    \displaystyle d = \sqrt{(-1+1)^2+(21+13)^2}
  2. (Parenthesis) Add:                              \displaystyle d = \sqrt{(0)^2+(34)^2}
  3. [√Radical] Simplify:                             \displaystyle d = \sqrt{(34)^2}
  4. [√Radical] Evaluate:                           \displaystyle d = 34
