Find the solution of the initial value problem ˙~x = F~ (~x) with ~x(0) = ~x0 for F~ (~x) = −µx1 −x2 + x 2 1 , ~x = x1 x2 , ~x0

= a b for arbitrarily chosen (a, b, µ) ∈ R 3 . Is the solution ~u(t; a, b, µ) a continuous function of all variables (t, a, b, µ) ∈ R 4 ? Give an interval t ∈ [−a, a] and an open neighbourhood (a, b, µ) ∈ U ⊂ R 3 such that ~u ∈ C([−a, a] × U, R 3 ).

Answer:

(a) n(t) = P(0)*e^(0.010939940t)

(b) 12,674,681 (nearest unit)

(c) 14 years (nearest year)

Step-by-step explanation:

rate = 1.1% / year = 1.011

(a)

P(0) = 12,000,000  = population in 2010

In compound interest format, after t years

P(t) = P(0)* (1.011)^t

Given format = P(0)* e^(rt)

therefore

e^(rt) = 1.011^t       use law of exponents

(e^r)^t = 1.011^t

e^r = 1.011

r = log_e(1.011) = 0.010939940   (to 9 decimal places)

required formula is

n(t) = P(0)*e^(0.010939940t)

(b)

in 2015,

P(0)=12000000, n = 5 (years after 2010)

n(5) = 12000000*e^( 0.010939940 * 5 ) = 12,674,680.6 = 12,674,681 (nearest unit)

(c)

to reach 14 million, we equate

n(t) = 14,000,000

12,000,000 *e^(0.010939940*t) = 14,000,000

e^(0.010939940*t) = 14000000/12000000 = 7/6

take log on both sides

0.010939940*t = log(7/6)

t = log(7/6) / 0.010939940 = 14.091 years = 14 years to the nearest year.

See graph attached.  Y-axis is in millions, x-axis is in years.

Combine like terms:
<span>3y + 5z + 8y - 3z = (3y + 8y) + (5z - 3z) = 11y + 2z

So you would choose A confidently
