Paying $46.50 monthly, a financial calculator says it will take 30 months to pay off the loan.
Paying $71.00 monthly, it will take 19 months to pay off the loan.
Making the higher payment, Drew can pay off his loan 11 months sooner.
_____
If you solve the amortization formula for n, the number of payments, you get
... n = -log(1-(Pi/A))/log(1+i)
where P is the principal value of the loan (1250), i is the monthly interest rate (.007), A is the monthly payment (46.50 or 71.00).
Answer:
Step-by-step explanation:
This is a question that uses the Pythagorean Theorem.
a = 35 feet
b = x which is the height of the tree.
c = 3*x + 1 so we are trying to find x. Substitute into a b and c
a^2 + b^2 = c^2
35^2 + x^2 = (3x + 1)^2
35^2 + x^2 = 9x^2 + 6x + 1 Subtract x^2 from both sides.
35^2 = 8x^2 + 6x + 1 Subtract 35^2 from both sides.
0 = 8x^2 + 6x + 1 - 35^2
0 = 8x^2 + 6x - 1224
Does this factor?
(x + 12.75)(x - 12)
x - 12 = 0 is the only value that works.
x = 12
The tree is 12 feet high.
Note: I used the quadratic formula to solve this.
Answer:
<h2>24x^2-13x-2</h2>
Step-by-step explanation:
Area of rectangle = Length ×Breadth
What you are trying to solve is 4000 divided by 4 which is 1000
Y=mx+b
m=slope, b=y-intercept
m=(y2-y1)/(x2-x1), b=value of y when x=0
m=(3--1)/(-2-4)
m=4/-6
m=-2/3, now we have:
y=-2x/3+b, we can solve for b using any point, I'll use (4,-1)
-1=-2(4)/3+b
-1=-8/3+b
-3/3+8/3=b
5/3=b so
y=-2x/3+5/3
