<u>Answer:</u>
The correct answer option is B. 0.21.
<u>Step-by-step explanation:</u>
We are to find the value of 
using the law of cosines.
We know that the formula of the cosine rule is given by:
So substituting the given values in the above formula:
cos C = 0.21
Answer:
54.50
Step-by-step explanation:
10 * 5 + 9%
50 + 9% (4.50) = 54.50
All you have to do is put 36/125. This will get you .288. When rounded to the nearest percent, it is 28%.
Hack:
x% of 100=x
88% of 100=88
times both sides by 6
88% of 600=6 times 88
88% of 600=528
answer is 528
Answer:
y = 3x –5
Step-by-step explanation:
for slope-intercept form, y = mx + b
find the slope, m
(-8 -4)/(-1-3) = m
-12/-4 =m
3 = m
Substitute for m and use either coordinate for y and x to calculate b
4 = 3(3) + b
4 = 9 + b. Subtract 9 from both sides
4 –9 = b
–5 = b. Rewrite the equation with the calculated values for m and b
y = 3x –5
