You would use the cosine rule for this as you have 2 lines and are given the angle between them
The angle can be figured out easily as the clock has 12 equal components, meaning each component is 360/12 which is 30
As there are 5 components between A and B the angle is 30*5 =150
You can plug all of this into the cosine rule
a^2= b^2+c^2-2bcCos(A)
So a = sqrt( 10^2 +7^2 -(2*10*7) cos150)
a=16.4 to 3 sf
Answer:
If a student with 2 absences got a score of 12, we can affirm that the student got 6 points for every absence she or he had.
Therefore, if a student had 3 absences and the results varied inversely with the number of absences they had, it means that her or his score would be: 3 * 6 = 18 points.
<u>The correct answer is 18 points.</u>

Answer:
r = 13, 3
Step-by-step explanation:
| r - 8| = 5
All solutions for r by breaking the absolute value into the positive and negative components
r = 13, 3
Answer:
H. x = 1 , slope is undefined
Step-by-step explanation:
The slope of a vertical line is always undefined.
If you think about it, no matter what y value you use, the x will always be 1 (In this equation). Such as:
(1, 5)
(1, 8)
(1, -12914)
(1, 272)
With x always being one, it forms a vertical line parallel to the y-axis
