Answer:
2am
Step-by-step explanation:
We know that the temperature variation is depicted by trignometric function. The total cycle of any trignometric function can be divded into four parts. In first quarter of the cycle, the value rises from mean to max. In 2nd quater, it falls to mean again. In third quarter it lowers to minimum and in last quarter rises to mean again.
Dividing the daily temperature variation cycle into four quaters of 6 hours each. The difference in time for any trignometric function to reach from its maximum value to minimum value is one-half of the cycle. In this case, it will be 12 hours.
Therefore daily temperature will fall to its minimum value 12 hours after reaching maximum that is at 2 am
Answer:
vertex = (- 1, - 4.5 )
Step-by-step explanation:
Given
f(x) = 
(x - 2)(x + 4)
The vertex lies on the axis of symmetry which is positioned at the midpoint of the zeros.
To find the zeros let f(x) = 0, that is
(x - 2)(x + 4) = 0
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
x + 4 = 0 ⇒ x = - 4
The x- coordinate of the vertex is therefore
x = 
= 
= - 1
Substitute x = - 1 into f(x) for corresponding y- coordinate
f(- 1) = (- 1 - 2)(- 1 + 4) = × - 3 × 3 = 0.5 × - 9 = - 4.5
Coordinates of vertex = (- 1, - 4.5 )
