we are given

f(x)=5|x-8|+20

where

x is number of hours

f(x) is dollars he charges

The charges will be lowest when absolute value will become 0

so, we can set value inside absolute function equals to 0

and then we can solve for x

x-8=0

x=8 hours............Answer

Answer:

The function which is used to find number of Dollars charged by charles

f(x)=5|x-8|+20

Minimum Hourly rate can be calculated, when

|x-8| is minimum.

→|x-8|=0,as Modulus of function is always ≥0.

→x-8=0 ∧ → -(x-8)=0

→x=8 ∧ x=8

Lowest hourly rate that Charles charges is , f(8)

=5×|8-8|+20

=5×0+20

=$20 per Hour

Svetradugi [14.3K]
Events A and B are independent if the following holds true:

P(A ∩ B) = P(A) * P(B)

where P(A ∩ B) is the probability of A and B, P(A) is the probability of A, and P(B) is the probability of B.

Setting A = "snow" and B = "cold weather", and plugging in the above numbers will give you the answer.

What do the differences between the points (as shown on the graph) represent?
Mekhanik [1.2K]

Answer:

They represent the rise and run of the graph.

Step-by-step explanation:

<em>The difference between the x-axis of the points represents the "run" of the graph (or how much you should run along x-axis to get to the next point.)</em>

<em>The difference between the y-axis of of the points represents the "rise" of the graph (or how much you should rise up the y-xis to get to the next point).</em>

The ratio of rise to run is the slope of the graph, which tells us  how many steps should we take on the y-axis for every step we move forward on the x-axis.

Mama L [17]
We can tell from the data that there is a midpoint between the lowest and highest point of the clock, which is at a height of 9.5 feet.
Moreover, the lowest point occurs at 6 o clock, and the highest occurs at 12 o clock.
The amplitude of variation from the mid-point is 0.5 feet given by (10 - 9) / 2.
Finally, the time period for the equation is 12 hours. Thus, the answer is:
h = 0.5cos(πt/6) + 9.5, option B
