Answer:

Step-by-step explanation:

It takes 15 years to get 2.5 times the sum at 10% p.a.

Let the principal be 'P'.

Let the amount be '2.5P'

Rate = 10%

Amount = Principal - Interest

2.5 P = P - Interest

Interest = 1.5 P

So, we get that

$1.5P =\frac{P*R*T}{100} \\1.5 * 100 = 10 * T\\T = 15 years$

hope it helps :)

Answer:

see explanation

Step-by-step explanation:

Calculate the slopes between pairs of the 3 points using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 9, 3) and (x₂, y₂ ) = (- 3, 9)

m = $\frac{9-3}{-3-(-9)}$ = $\frac{6}{-3+9}$ = $\frac{6}{6}$ = 1

Repeat with (x₁, y₁ ) = (5, 1) and (x₂, y₂ ) = (- 3, 9)

m = $\frac{9-1}{-3-5}$ = $\frac{8}{-8}$ = - 1

If lines are perpendicular then the product of their slopes = - 1 , then

1 × - 1 = -1

Thus there is a right angle between the 2 lines

Then triangle is right- angled
