For 0 < or = n < or =10, find a formula for Pn, the payment in year n on a loan of 105000 dollars. Interest is 7 percent p
pshichka [43]

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))

If you have a right triangle one angle is twice the size of the other. What is the measure of the smallest angle?
Lapatulllka [165]
30 degrees.

Because a right triangle has a 90 degree angle; and a total of 180 degrees.
Therefore:

180-90-2x-x=0
Solve for X:

90-3x=0
3X=90
X=30.
