Nice work on getting part (a) correct.
To complete part (b), we plug x = 8 into the derivative calculated for part (a)
47 goes in the box

As for the multiple choice section, you have chosen the correct answer. It is choice C.
f ' (8) = 47 can be interpreted as "at exactly 8 words, the memorization time is increasing by exactly 47 seconds per word".
Phrased another way, it's taking 47 seconds longer to memorize another word at exactly the x = 8 word marker.

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
1.5 =
ln1.5 = k ln 1.02
k = ln 1.5 / ln 1.02
= .4054 / .0198
= 20.47 years .
Answer:
x=41
Step-by-step explanation:
x is your hypotenuse , and cuz its a right triangle you can use pythogorean theorem so +
=
, and c is the same as "x"
once u simplify that u end up with c=41 or in your case x=41 :)
