Lucas bought a refrigerator.his total cost of 1,331 included sales tax at a rate of 8% additional,untaxed delivery charge of 35. how much sales tax did he pay? a.72 b.106$ c.120 d.96 urgent

The correct answer is option D.

Step-by-step explanation:

Total cost paid by Lucas = $1,331

Cost of the refrigerator = c

Sales tax on the refrigerator = 8% of  c

Charges to deliver refrigerator = $35

c = $1200

Amount Sales tax on the refrigerator = 8% of  c

Lucas had paid 96 dollars as a sales tax.

answer-

solution-

the given function,

the parent cosine function is,

1. for

as there is a negative sign in the cos x, so all the points with coordinate (x, cos x) becomes (x, -cos x)

∴ it is reflected over x-axis.

2. for

as a scale factor of 0.1 (i.e < 1) is multiplied, so it is compressed by a factor of 0.1

3. for

as 4 is subtracted from the f(x), so all point with coordinate (x, f(x)) becomes (x, f(x)-4)

∴ it is translated 4 units down.

therefore, a series of processes

yield the given function from its parent function.
