sergeinik [125]3 years ago
7 0

Answer:

49.18$

Step-by-step explanation:

Price of meal = 38.95$

sales tax = 7%

Price after sales tax = 38.95 + 7% of 38.95

=> 38.95 + 7/100 * 38.95

=> 38.95 + 2.73

=> 41.68$

Tip on meal plus sales tax = 18%

Therefore, the money ray family pay is =  41.68 + 18/100 *41.68

=> 41.68 + 7.50

=> 49.18$

Use the factor Theorem to determine whether h(x)=x-1 is a factor of f(x)=14x^99-65x^56+51.
Nuetrik [128]

Factor theorem: if x-k is a factor of p(x), then p(k) = 0. The same can be said in reverse: if p(k) = 0, then x-k is a factor of p(x).

In this case, x-1 = x-k so k = 1. We'll plug this into f(x) below

f(x) = 14x^99 - 65x^56 + 51

f(1) = 14(1)^99 - 65(1)^56 + 51 ... replace every x with 1

f(1) = 14(1) - 65(1) + 51

f(1) = 14 - 65 + 51

f(1) = -51 + 51

f(1) = 0

The result is 0, so h(x) = (x-1) is a factor of f(x) = 14x^99-65x^56+51

Answer: Choice A) yes
