A triangle has vertices on a coordinate grid at N (7,3), 0(-8, -3), and
Leokris [45]

Answer:

d\approx 16.16\ units

Step-by-step explanation:

<u>Distance Between two Points in the Plane</u>

Given two points A(x,y) and B(w,z), the distance between them is:

d=\sqrt{(z-y)^2+(w-x)^2}

The triangle formed by the points N (7,3), 0(-8, -3), and  P(-8,-8) is shown in the image provided.

We are required to find the distance between N and O:

d=\sqrt{(-3-3)^2+(-8-7)^2}

d=\sqrt{(-6)^2+(-15)^2}

d=\sqrt{36+225}

d=\sqrt{261}

Since 261=9*29:

d=3\sqrt{29}

\mathbf{d\approx 16.16\ units}

You are the administrator of an annual essay contest scholarship fund. This year a $84,000 college scholarship is being divided
shutvik [7]

The winner got $70,000 and the runner up got $14,000

Let the winner be represented by x and runner up by y

Data given;

  • Amount to be shared = $84000
  • x = 5y

This is a simple case of ratio i.e 1 : 5

<h3>Equation</h3>

x = 5y\\84000 = 5y + y\\84000 = 6y\\y = 14000\\

The runner up received $14000. let's use this data to find how much the winner got.

x = 5y \\x = 5 * 14000\\x = 70000

From the calculations above, the winner got $70,000 and the runner up got $14,000.

3.920 * (1.018)^x = 5.500<br><br>X=?​
Andrei [34K]

Answer:

19

Step-by-step explanation:

3.920(1.018)ˣ = 5.500

  • First we can divide both sides by 3.920 to get: (1.108)ˣ = 1.403
  • Then we can take the natural log of both sides to get: ln[(1.108)ˣ] = ln(1.403)
  • We can then use logarithmic rules to move the x exponent to the front: xln(1.108) = ln(1.403)
  • Then we can divide both sides by ln(1.108) to get: x=\frac{ln(1.403)}{ln(1.018)}
  • Then using a calculator we get x = 18.98 ≈19
