Answer:
<em>19</em>
Step-by-step explanation:
has a factor
and
when divided by
, remainder is 20.
To find:Remainder when divided by (x-1) ?
Solution:
is a factor
when we put this value of x to the function, it will become 0.
i.e.

Remainder is 20 when f(x) is divided by 
i.e.


Solving (1) and (2), Multiply equation (1) by 2 and adding to (2):

By equation (1):

So, the equation becomes:


So, when divided by (x-1), remainder will be <em>19</em>.

The formula for depreciation is:

Where x = Initial value,
y= Amount after depreciation.
r= Rate of depreciation,
t = time (in years)
According to given problem,
x = 1040, y= 944 and t = 12 months =1 year.
So, first step is to plug in these values in the above formula, So,

944 = 1040 (1 -r)
Divide each sides by 1040.
0.907692308 =1 - r
0.907692308 - 1 = -r Subtract 1 from each sides.
-0.092307692 = -r
So, r = 0.09 or 9%.
Now plug in 0.09 in the above equation to get the depreciation equation. So,

So, 
b) To find the value of the bike after 5 months,
plug in t = 5 months= 5/12 = 0.41667 years in the above equation of depreciation.
So, 
y = 1040 * 0.961465659
y = 999.9242852
y = 1000 (Rounded to nearest integer).
Hence, the value of the bike after 5 months is $1000.
Using the law of cosine for Triangle KJL, we can write:

Using the values of k,j and l, we can write:

Rounding to nearest integer, the measure of angle J will be 48 degrees.
So option B gives the correct answer
Their both the answer hope this helps
