Answer:
x=−16/3 or x=2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3x2+10x−8=24
Step 2: Subtract 24 from both sides.
3x2+10x−8−24=24−24
3x2+10x−32=0
Step 3: Factor left side of equation.
(3x+16)(x−2)=0
Step 4: Set factors equal to 0.
3x+16=0 or x−2=0
sin 3 x = sin ( 3 x + 2 π ) = sin [ 3 ( x + 2 π/ 3 ) ] = sin 3 x
This means "after the arc rotating three time of ( x + ( 2 π /3 ) ) , sin 3x comes back to its initial value"
So, the period of sin 3x is 2 π /3 .
Answer:
7π/6
Step-by-step explanation:
The way to convert radian to degree is to convert π to 180 degrees. We know that π radian is equal to 180 degrees and therefore.
A) 7(180)/6 = 7(30) = 210 degrees
B) 6(180)/7 = 1080/7 = approx 154.2 degrees
C) 7(180)/3 = 7(60) = 420 degrees
D) 3(180)/7 = 540/7 = approx 77.1 degrees
When we convert π rad to 180 degrees and evaluate, we will get the rad value in degree form.
Therefore, 7π/6 = 210 degrees. Hence, A is the answer.
