Answer:
C. Yes Devon should have evaluated f(3).
Step-by-step explanation:
She substituted the wrong value. For x - 3 to be a factor f(3) must equal 0.
f(3) = 3^3 + 3^2 - 10(3) + 8 = 27 + 9 - 30 + 8
= 14, so x- 3 is not a factor anyway but she did substitute the wrong value.
Answer:
m∠5= 130°
Explanation:
If lines A and B are parallel we can assume that the angles in the same locations are equal
<h3>
Answer: Bottom left corner (southwest corner)</h3>

The left endpoint is x = 4, but we don't include this endpoint because of the open hole. We use a parenthesis to indicate "don't include the endpoint"
The right endpoint is positive infinity. We always use a parenthesis with either infinity since we cannot reach infinity
The interval from 4 to infinity is written as
which is like saying

Answer:
x ≈ 35.6
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos16° =
=
( multiply both sides by 37 )
37 × cos16° = x , then
x ≈ 35.6 ( to the nearest tenth )
