Answer:
k = -13
Step-by-step explanation:
-143/11 = -13
That means that it has 2 complex roots, and it has no x intercepts, means that it doesn't touch the x axis at all
Answer:
A
Step-by-step explanation:
11 3/4 - 8 1/2 = 3 1/4
Answer:
Option D: 
is the correct answer.
Step-by-step explanation:
Given that:
3/4 inches on map are equal to 
miles
We will find the unit rate in term of inches.
Total distance covered by Bonnie according to map;
Total distance = 
Total distance = 
Actual distance = 
Actual distance = 
Hence,
Option D: is the correct answer.
Answer:
The measure of angle θ is 7π/6. The measure of its reference angle is <u>210°</u>
and sin θ is <u>-1/2</u>.
Step-by-step explanation:
The correct question is:
<em>The measure of angle θ is 7π/6. The measure of its reference angle is ___</em>
<em>and sin θ is ___</em>
180° is equivalent to π radians. To transform 7π/6 radians to degrees, we have to use the following proportion:
180° / π radians = x° / (7π/6 radians)
x = (180/π) * (7π/6 radians)
x = 210°
And sin(210°) = -1/2
