Answer:
The value of k is -21
Step-by-step explanation:
ax² + bx + c = 0
Sum of the roots = -b/a
3x² + kx + 1 = 0
= sum of the roots = -k/3
-k/3 = 7
Now, Multiply both side by (-3) we get,
(-3)-k/3 = 7(-3)
k = -21
Thus, The value of k is -21

Given:
Annual salary: 56,010
Social Security tax rate: 6.2%
Medicare tax rate: 1.45%
Both these taxes are computed based on the annual salary.
Social Security tax:
56,010 x 6.2% = 3,472.62
Medicare Tax:
56,010 x 1.45% = 812.145 or 812.15
Total taxes paid:
3,472.62 + 812.15 = 4,284.77
Answer:
42
Step-by-step explanation:
Hey There!
Angle 3 and Angle 4 are a pair of supplementary angles meaning that added together they will equal 180
So if angle 4 is given to find angle 3 all we have to do is subtract the angle that is given from 180
180-138=42
Therefore angle 3 = 42
