61
Step-by-step explanation:
4 × (8 + 5) + 9
Parentheses first
4 × (13) + 9
Then multiply
52 +9
Then add

Answer:
y = 4 sin( 0.5t -
) - 2
y = a sin ( 2t -
) + 2
Step-by-step explanation:
In the first question,
amplitude = 4
Period = 
phase shift = 
Vertical shift = -2
Angular velocity , w = 
Here, w =
= 0.5
The general equation of a wave is
y = a sin( wt + ∅ )
Putting above values in the equation,
y = 4 sin( 0.5t -
) - 2
In the second question,
Amplitude is not given so we will take it as a.
time period = 
w = 2
Phase shift = 
Vertical shift = 2
The equation is
y = a sin ( 2t -
) + 2
.75 75% 3/4 is the correct answer
Answer:
15
Step-by-step explanation:
The value of x is 67°
What are corresponding angles?
Two angles are said to be corresponding if they occupy the same position at the point of intersection of a parallel line and a transversal that crosses it.
Analysis:
∠H = ∠I = 67° ( corresponding angles)
∠H + ∠I + ∠A = 180
67 + x + 46 = 180°
113 + x = 180
x = 180 - 113 = 67°
In conclusion, x = 67°
