For the answer to the question above,
<span>V(n) = a * b^n, where V(n) shows the value of boat after n years.
V(0) = 3500
V(2) = 2000
n = 0
V(0) = a * b^0 = 3500
a = 3500
V(2) = a * b^2
2000 = 3500 * b^2
b = sqrt (2000/3500)
b ≈ 0.76
V(n) = 3500 * 0.76^n
We can check it for n = 1 which is close to 2500 in the graph:
V(1) = 3500 * (0.76)^1
V(1) = 2660
And in the graph we have V(3) ≈ 1500,
V(n) = 3500 * (0.76)^3 ≈ 1536
Now n = 9.5
V(9.5) = 3500 * (0.76)^(9.5)
V(9.5) ≈ 258</span>
Present area = 120 * 80 = 9600 ft^2 so the new area will be 9600 + 4400 = 14000
So if increase in length = x we have
(x + 120)(x + 80) = 14,000
x^2 + 200x + 9600 - 14000 = 0
x^2 + 200x - 4400 = 0
x = 20 feet answer
2/3 of 1¾ is simply their product, let's firstly convert the mixed fraction to improper fraction.
Well lets lay it out
2323 6969
first get 2323 and try its multiples.
2323 x 2 = 4646
2323 x 3 = 6969
so what 2323 and 6969 have in common are the multiple 3
Answer: they are equivalent because they can be divided into each other. HOPE I HELPED!! :P <span />
Rational
Zeros in a quadratic equations are equal distances from the axis of symmetry. If one root is rational, the other must belong to the same number set. Therefore, the answer is rational.
