This question is under the Analytic Geometry topic in Math.
In order to find the distance between two points, we may use the concept of the Pythagorean Theorem but to simplify things out, we may use the distance formula between two points:
d= \sqrt{( x_{2}-x_1)^2 + (y_2-y_1)^2 }
Now, let us just substitute values:
<span>d= \sqrt{( 12-8)^2 + (11-8)^2 }
</span>d= \sqrt{16+9}
d=5

So the distance between the points (8,8) and (12,11) is, they are 5 units apart.

John and rachel share £2400 prize money at a ratio of 2:4. How much do they each get?
Stels [109]

Answer: John:£800

Rachel:£1600


Step-by-step explanation:

Since John and Rachel shared £2400 in the ratio 2:4, it means that £2400 was equal to(2+4) units, which is 6 units.

Thus, each unit is £2400/6= £400

Hence, John got £400x2=£800, and Rachel got £400x4=1600.

Hope u understand my solution. :)

Answer:

C. (x-2)^2=7

Step-by-step explanation:

What you have to do first is to get rid of the 3 in the x^2 so you will divide 3 by the whole thing to get x^2-4x=3.

You will then divide -4 by 2 and then square the answer to get 4.

You will then add the 4 into the end of the equation and to the 3 to get x^2-4x+4=7.

You will then make into a perfect square (x-2)^2=7 and that is your answer.
