Answer: x ≈ 1.59688927, −1.60312387, −4.67045686, 4.69039614, 7.872914, −7.91513776, −10.89002194

Step-by-step explanation:

Solve for x by simplifying both sides of the equation, then isolating the variable.

Simplify 2*cosx*(2x+30°) + √3=0

Simplify each term.

Apply the distributive property.

2 cos ( x ) ( 2 x ) + 2 cos ( x ) * 30 ° + √ 3 = 0
Multiply 2 by 2
4 cos ( x ) x + 2 cos ( x ) *30 ° + √ 3 = 0
Multiply 30 °by 2
4 cos ( x ) x + 60 cos ( x ) + √ 3 = 0
Reorder factors in 4 cos ( x ) x + 60 cos ( x ) + √3
4xcos(x)+60cos(x)+√3=0
Graph each side of the equation. The solution is the x-value of the point of intersection. x ≈ 1.59688927 , − 1.60312387 , − 4.67045686 , 4.69039614 , 7.872914 , − 7.91513776 , − 10.89002194

Change 225° to radian measure in terms of pi

a_sh-v [17]

Answer:

$\frac{5\pi }{4}$

Step-by-step explanation:

To convert from degree to radian measure

radian measure = degree measure × $\frac{\pi }{180}$

Hence

radian measure = 225 × $\frac{\pi }{180}$ = $\frac{225\pi }{180}$ = $\frac{5\pi }{4}$

A plumber and his assistant work together to replace the pipes in an old house. The plumber charges $30 an hour for his own labo

Korvikt [17]

Answer:

The plumber worked 50 hours, and his assistant worked 25 hours.

Step-by-step explanation:

Since a plumber and his assistant work together to replace the pipes in an old house, and the plumber charges $ 30 an hour for his own labor and $ 20 an hour for his assistant's labor, and the plumber works twice as long as his assistant on this job, and the labor charge on the final bill is $ 2000, to determine how long did the plumber and his assistant work on this job the following calculation must be performed:

40 x 30 + 20 x 20 = 1200 + 400 = 1600

50 x 30 + 25 x 20 = 1500 + 500 = 2000

Therefore, the plumber worked 50 hours, and his assistant worked 25 hours.
