Answer:
π
Step-by-step explanation:
Solve for x on the interval [0, 2pi]
Given the equation
Sinx = cosx + 1
Square both sides of the equation
Sin²x = (cos x + 1)²
Sin²x = cos²x + 2cos x + 1
Since Sin²x = 1 - cos²x
1 - cos²x = cos²x + 2cos x + 1
Collect like terms
1-1-cos²x-cos²x-2cos x = 0
-2cos²x-2cos x = 0
-2cos²x = 2cos x
-cosx = 1
cos x = -1
x = arccos -1
x = 180 degrees
<em>Hence the value of x = π</em>
Answer:
87 2/10 km^2. hope it's helpful
Step-by-step explanation:
area = l X w
= 8 km X 10 9/10 km
= 8 X 109/ 10 km^2
= 872/10 km^2
Y is less than or equal to 0
Answer:
$18.03 to nearest cent
Step-by-step explanation:
There are 52 weeks in the year so the weekly income = $37,500 / 52
So for a 40 hours week hourly pay = 37,500 / (52 * 40)
= $18.03 to nearest cent
Answer:
x = 13
Step-by-step explanation:
180-52=10x-2
130=10x
13=x
