Question

1. Find a if the distance between (a, 2) and (3, 4) is 8.​

Answer 1

Answer:

Given:

2 points on the coordinate axis

i) (a,2)

ii) (3,4)

Distance between the given points = 8 units

To find:

Value of (a)

Formulas used:

let distance be denoted as "d"

d = √{(x2 - x1)² + (y2 - y1)²}

Calculation:

d = √{(x2 - x1)² + (y2 - y1)²}

=> 8 = √{(3 - a)² + (4 - 2)²}

=> 8 = √{(3 - a)² + 2²}

Squaring on both sides:

=> 64 = (3 - a)² + 4

=> 60 = (3 - a)²

Square root on both sides:

=> 3 - a = √60 = 7.745

=> a = 3 - 7.745 = - 4.745.

So the answer is (a = - 4.745)
