Answer:
Select the one which meets the following characteristics.
Step-by-step explanation:
y = cos(2x)
Characteristics:
Mean line at y = 0
Amplitude = 1
Period = 360/2 = 180° or pi radians
i.e one complete cos cycle is 0 to 180, next is 180 to 360 and so on
Range : from -1 to 1
We need to solve the equation: w² + 36 = 12w
⇒ w² - 12w + 36 = 0
⇒ w² - 6w - 6w + 36 = 0 (Breaking 6w such that their product is 9w²)
⇒ w × (w - 6) - 6 × (w - 6) = 0 (Extracting common factors)
⇒ (w - 6) × (w - 6) = 0
⇒ (w - 6)² = 0
⇒ w = 6
Hence, the correct answer is 6 which is the fourth option from the replacement set
Answer:
The equation would be y = 5x - 11
Step-by-step explanation:
To find this line, start with the slope. Since it is parallel to the first line and parallel lines have the same slope, we know the slope to be 5. Given this we can use point-slope form and solve for y to get the equation.
y - y1 = m(x - x1)
y + 1 = 5(x - 2)
y + 1 = 5x - 10
y = 5x - 11
