She spends 2.50 a week times 6 weeks is 15$
Answer: Pn= 10500(1+ 0.07(11-n))
Step-by-step explanation:
From the question it is given that
Pn= 10500 + 7% of Dn eqn 1
Where Pn is payment at year n
And Dn is outstanding debt at year n
n= 1,2,3...,10
D1= 105000
D2=105000-10500
Dn=105000-10500(n-1) eqn2
Therefore, substituting eqn2 into eqn1
Pn= 10500+7% of (105000-10500(n-1))
Pn= 10500+ 0.07(105000 - 10500(n-1))
Pn= 10500(1+ 0.07(10 - (n-1)))
Pn= 10500(1+ 0.07(11-n))
It could be anything, except the number whose square is integer...
example -√10, -√11, -√12, -√13, -√14, -√15, -√17
The answer is <span>length = 10 yd, width = 2 yd
proof
</span><span>The length of the playground is 5 times longer than its width, it means
l=5w, but 10= 2x5 so we can write l= 5w,
and Area = 20 =l x w = (5x2) x 2 =20</span>
