Answer:

Step-by-step explanation:
We know that:

And we want to find:

Remember that there is a trigonometric identity that relates the
function with the
function

Then if
this means that:

Finally:

The answer is -11/2, 9/2
Explanation
You have to rewrite the absolute value equation as two separate equations.
2x+1=10
2x+1=-10
Then you solve for X in each equation.
2x+1=10 would give you 9/2
2x+1=-10 would give you -11/2
So your final solutions would be x1= -11/2 x2= 9/2
Answer:
$511
Step-by-step explanation:
If each liter costs $73$, then 7 liters is 7 times 73, which is $511.
m_6 + m_8 = 180º because they form a straight line.
So, (2x-5) + (x+5) = 180
3x = 180
x = 60
So, m_115º (2•60 - 5 = 115)
Also, because the two lines are parallel m_6 = m_3 by alternate interior angles.
So, m_3 = 115º
Answer: There are 177100 possible groups.
Step-by-step explanation:
Given: Total employees = 25
Number of employees wants to choose = 6
The combination of n things taken r at a time is given by:-

Put n = 25 and r= 6, we get

Hence, there are 177100 possible groups.
