hope i helped
Let's check.
x = 5π/24
4x = 5π/6
cos 4x = cos(5π/6) = cos 150° = -√3/2
cos² 4x = (-√3/2)^2 = 3/4
4 cos² 4x -3 = 4 (3/4) - 3 = 0
Answer: TRUE
Answer:
x<5
Open circle at 5 going to the left
x >1
Open circle at 1 going to the right
Step-by-step explanation:
7x -19 < 16
Add 19 to each side
7x -19 +19< 16+19
7x< 35
Divide by 7
7x/7 < 35/7
x<5
Open circle at 5 going to the left
9+3x>12
Subtract 9 from each side
9-9 +3x >12-9
3x >3
3x/3 >3/3
x >1
Open circle at 1 going to the right
Answer:
Slope= 30
Speed = 30 miles per hour
Step-by-step explanation:
Given two points the slope will be change in y over change in x
OR (y-y1)/(x-x1)
(120-60)/(2-1) = 60/2 = 30miles/hr
Answer:
arc of WXY= 224°
Step-by-step explanation:
measure of angle C is half of the WXY arc
this means WXY×1/2=C
112°=1/2 WXY (cross production)
WXY=2×112°
WXY=224 °
