Answer:
C. The charge of each minute of a call is $0.40
Step-by-step explanation:
We look at the point (1, 0.4)
We know that our x = 1 is 1 minute of the call.
We know that y = 0.4 is the cost when 1 minute of the call has elapsed.
Therefore, our answer is C.
Answer:
The green box is -3
Step-by-step explanation:
You are reading from a graph, so it is more important perhaps, to pick clear points rather than easy to handle points.
The easiest two points you could use would be
(0,4)
(1, 1)
Slope
m = (y2 - y1)/(x2 - x1)
y2 = 4
y1 = 1
x2 = 0
x1 = 1
m = (4-1)/(0 -1)
m = 3/-1 = - 3
Y intercept
b = 4 from the point 0,4
Line
y = - 3x + 4
Answer:
Only options A and B are correct, i.e. y = sin∅ and y = cos∅.
Step-by-step explanation:
The graphs that oscillate, should be periodic in nature and continuous functions.
We know all trigonometric functions are periodic in nature. But not all trigonometric functions are continuous.
The function is continuous if its values are defined at all angles and it should not be undefined for any particular angle.
We know the following facts:-
tan(90°) = ∞
sec(90°) = ∞
csc(0°) = ∞
cot(0°) = ∞
<u>Only sin and cos don't have values ∞ at any angle.</u> It means only sin and cos are continuous functions.
Hence, only options A and B are correct, i.e. y = sin∅ and y = cos∅.
The normally had small extended families.
They were a hunter-gatherer community
Sioux and Cheyenne tribes hunted buffalo
They were nomadic and almost completely dependent on buffalo
Look at the vertical line on the graph and find five
Place a dot there
Look at the horizontal line and look to the left to find -7
Place a dot there
Now, just get a ruler and draw a line connecting the two dots
