What is the distance between points A and B shown in the graph below
Bas_tet [7]

Answer:

D = 7\sqrt 2

Step-by-step explanation:

Given

A = (-3,-4)

B = (4,3)

Required

The distance between them

This is calculated as:

D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

So, we have:

D = \sqrt{(3-(-4))^2+(4-(-3))^2}

D = \sqrt{7^2+7^2}

D = \sqrt{2(7^2)}

D = 7\sqrt 2

Given the formula for future value annuity:
FV of annuity=P[(1+r)^n-1]/r
where:
P=principle
r=rate
n=time
the time taken to repay the loan will be:
1500=90[(1+0.06)^n-1]/0.06
90=90[(1+0.06)^n-1]
1=(1+0.06)^n-1
1+1=(1+0.06)^n
2=1.06^n
introduce natural log
ln2=nln1.06
n=ln2/ln1.06
n=11.8957=12 years
the answer is 12 years.
