It is D
Descending order means that the first polynomial factor must the largest. You can tell that by looking at its degree, or the exponent. In this, 11 is the largest degree. the smallest degree is a constant, which is 4. That is why it is D.
If the probability is 1/12, 75 people will receive a $25 gift card
Plug in 1
and −1
to get two values of r(x)
which is linear. From there you can get what a,b
are in ax+b.
Since
f(x)=g(x)(x+1)(x−1)+r(x)
we have
f(1)=g(1)(1+1)(1−1)+r(1)=r(1)=−10
f(−1)=g(1)(−1+1)(−1−1)+r(−1)=r(−1)=16
We know the remainder is of degree 1
, so
r(x)=ax+b
and now we know,
r(1)=ax+b=a+b=−10
r(−1)=ax+b=−a+b=16
so, solve
a+b=−10
−a+b=16
which yields, a=−13
b=3
, so
r(x)=−13x+3
Answer:
$120.25
Step-by-step explanation:
Divide 37 by 8. You get 4.625. Multiply 4.625 by 26. You get 120.25.
I hope this helps!
