Answer:
Step-by-step explanation:
From the function, y = cos (3x)
Inputting values of x (horizontal axis), x = pi
y = cos (3 × pi)
= -1 ( remember you are dealing with values in radians not degree)
So now graph 1 and 3 have the same values. So inputting, x = pi/2 into the function, y = cos (3x)
= cos ((3 × pi)/2)
= 0

Answer:
10°C
Step-by-step explanation:
The temperature is 50°F
Let's assume that 50°F = x°C
The formula is;
(x°C ×
) + 32 = 50°F
x°C = 50 - 32 = 18
x°C = 18
x°C =
× 18 = 10°C
So 50°F is equal to 10°C.
Answer:
Step-by-step explanation:
9y-4 = 50
9y = 54
y= 6
9y-4+7x+xy = 180
9(6)-4+7x+6x= 180
54-4+13x = 180
13x+50 = 180
13x = 130
x = 10
