A. 15
B.25
C.5
D.20
Answer: C
Step-by-step explanation: First, you have to make this word problem into a equation into standard form so 20 is our (y) because that is the additional charge, but our slope is 3, that is what they charge per hour.

23) Four vertices of a rectangle on a coordinate system are (2,5), (2, 2), (6,5), and (6,2). What is its perimeter?
The perimeter of the rectangle with the given vertices is 14 units.
To find the perimeter of a rectangle, we need to calculate the sum of all four sides.
Given the coordinates of the four vertices: (2,5), (2,2), (6,5), and (6,2), we can determine the lengths of the sides.
The length of the rectangle can be found by subtracting the x-coordinate of one vertex from the x-coordinate of another vertex. Similarly, the height of the rectangle can be found by subtracting the y-coordinate of one vertex from the y-coordinate of another vertex.
Let's calculate the lengths of the sides:
Length: (6 - 2) = 4 units
Height: (5 - 2) = 3 units
Since a rectangle has two pairs of equal sides, the length and height will be repeated.
Now, we can calculate the perimeter by adding up the lengths of all four sides:
Perimeter = 2 * (Length + Height)
Perimeter = 2 * (4 + 3)
Perimeter = 2 * 7
Perimeter = 14 units
Therefore, the perimeter of the rectangle with the given vertices is 14 units.

The temperature outside can be measured by listening to crickets chirp. If you count the
number of chirps per minute, the temperature can be found using the formula T = 1/4C+40
Define the domain and range of this function and describe reasonable values for each.
Answer:
Step-by-step explanation:
The outside can be measured by listening to a crickets chirp because the frequency of chirping varies according to temperature. To get a rough estimate of the temperature in degrees fahrenheit, count the number of chirps in 15 seconds and then add 37. The number you get will be an approximation of the outside temperature.

I had the question and got it right,
Let a function y represent the water level in a harbor measured in meters, and let x represent the number of hours
since high tide. At time x = 0, the water level is 19.5 meters (a maximum). At time x = 6.26 hours, the water level is
10.5 meters (a minimum). The period of the function is 12.5 hours.
After how many hours is the water expected to reach a depth of 17 meters for the first time? Round to the nearest
tenth of an hour
2.2hours
6.3hours
12.1hours
12.5hours
Answer:
2.2 hours
Step-by-step explanation:
The equation to graph is
4.5cos(4pi/25 x)+15
Find amplitude by subtracting min from max and dividing it by two. a=4.5
Find vertical shift k by finding the midline. Either add 4.5 to 10.5 or subtract 4.5 from 19.5. k = 15
The period is given to be 12.5. Use formula 2pi/b = period to find b. b = 4pi/25
Put the equation into graphing calculator and find what x equals when the graph is 17 (for the first time)
Given:
Maximum level = 19.5 mMinimum level = 10.5 mPeriod of function = 12.5 hoursRequired depth = 17 mNow,
The amplitude will be:
= [tex]\frac{Maximum - Minimum}{2}[/tex]
By substituting the values,
= [tex]\frac{19.5-10.5}{2}[/tex]
= [tex]4.5[/tex]
Equation of graph will be:
= [tex]4.5 Cos (\frac{4 \pi}{25} x)+15[/tex]
Now,
The vertical shift = [tex]10.5+4.5 = 19.5-4.5[/tex]
[tex]k = 15[/tex]
∴ [tex]\frac{2 \pi}{b} = period[/tex]
or,
[tex]b = \frac{2 \pi}{period}[/tex]
[tex]= \frac{4 \pi}{25}[/tex]
With the help of graphing calculator, the graph is 17 for "x = 2.2".
Thus the answer above i.e., "option 1" is correct.
