Answer:

Step-by-step explanation:

a ) The worth of Jean-Claude's gnome after 1 year

= 80000 x 1.02

=  £81600

b ) common ratio of geometric progression

= 81600 / 80000

= 1.02

c )  worth after 10 years

= 80000 x 1.02¹⁰

= 80000 x 1.21899

= £97519.55

d )

120000 = 80000 x 1.02^k

1.5 = 1.02^k

ln1.5 = k ln 1.02

k = ln 1.5 / ln 1.02

= .4054 / .0198

= 20.47 years .

What is the equation x^2+12x-3=16 written in the form (x-p)^2=q using the method of completing the square ?
Alexus [3.1K]

Step-by-step explanation:

{x}^{2}  + 12x -  3 = 16

{x}^{2}  + 12x = 19

{x}^{2}  + 12x + 36 = 19 + 36

(x + 6) {}^{2}  = 55

Natali [406]
There are quite a few websites that have factor lists. Also, if you can find the biggest number that goes into it, then all of the factors of that number go into it as well.
