Answer:
R (1 1/3 , 3) or (1.333 , 3)
Step-by-step explanation:
R (x,y)
x = 3 - (3 - (-2))/3 = 3 - (5/3) = 3 - 1 2/3 = 1 1/3
y = 2 + (5-2)/3 = 2 + 1 = 3
R (1 1/3 , 3) or (1.333 , 3)
Answer:
17) m = 35; n = 110
18) b = 90; c = 80; d = 100
Step-by-step explanation:
17)
2m = 70
m = 35
n + 70 + 70 + n = 360
2n + 140 = 360
2n = 220
n = 110
18)
b - 10 + b + 10 = 180
2b = 180
b = 90
b - 10 = c
90 - 10 = c
c = 80
b + 10 = d
90 + 10 = d
d = 100
Answer:
y = cos (2x + 2π) - 5/2
Step-by-step explanation:
y = a cos (bx + c) +d
a = Amplitude =1
period = 2π/b =π
b= 2
phase shift c/b = π
c/2 =π
c =2π
vertical translation = 5/2 units
d = -5/2 downwards
therefore substituting the values
y=1 cos (2x +2π) - 5/2
y = cos (2x + 2π) - 5/2 ;equation for the function
6 equals 6*10^0 which os 6*1=6
