What is the distance between (4, 7) and (-8, 3)? Round to the nearest tenth.

Answers

Answer 1

Answer:

The distance is approximately 12.6.

Step-by-step explanation:

Moving from (-8, 3) to (4, 7), we see x (the horizontal dimension) increasing by 12 and y (the vertical dimension) increasing by 4.  Think of 12 and 4 as the legs of a right triangle whose hypotenuse represents the distance between these two given points.

This distance, from the Pythagorean Theorem, is

d = √(12^2 + 4^2) = √(144 + 16) = √160 = √16√10.

The desired distance is approximately 12.6.

Answer:

AY = 4.8YD = 2.4

Step-by-step explanation:

Corresponding sides of the triangles are ...

  ΔFUN  . . .   ΔDAY

  UF = 10 . . .  AD = 6

  FN = 4 . . .  DY

  NU = 8 . . .  YA

Corresponding sides are proportional, so we have ...

  DY/4 = AD/UF = 6/10

  DY = 4(0.6) = 2.4

and

  YA/8 = 6/10

  YA = 8(0.6) = 4.8

The side lengths are ...

  AY = 4.8, YD = 2.4
