The total cost to rent the Kayak will be $50.50
Step-by-step explanation:
Let h be the number of hours
Given
Charges per hour = $8.50
Renting Charges = $25.00
The renting charges are constant and will be used only once while the per hour charges will be calculated as number of hours change.
The function will be written as:
[tex]f(h) = 8.50h +25.00[/tex]
Here h is the number of hours.
From 11:30 AM to 02:30 PM makes three hours. So, to find the cost for 3 hours we have to put h = 3
[tex]f(h) = 8.5(3) + 25.00\\= 25.5+25.00\\= 50.5[/tex]
Hence,
The total cost to rent the Kayak will be $50.50

1) There are at least 3 ways to show that 2 functions are inverses. However, only ONE method is a valid proof. Although Methods A and B might convince you that the functions are inverses, they are NOT acceptable methods to verify that functions are inverses. Complete the work for each method below:
Method A: Given () = 3 − 4 and () = +4/3
Show that these are inverse functions by finding ^−1 () and showing that it is the same as ().
Method B: Given () = 3 − 4 and () = +4/3
Show that these are inverse functions by showing that when the output of one function is used for the input of the other function, the final output is equal to the original input value. (you may choose any initial input)
Method C: Given () = 3 − 4 and () = +4/3
Verify that these are inverse functions by showing that (()) = AND (()) =
The notation that we use really depends upon the problem. In most cases either is acceptable.
For the two functions that we started off this section with we could write either of the following two sets of notation.
f(x)=3x−2f−1(x)=x3+23g(x)=x3+23g−1(x)=3x−2f(x)=3x−2f−1(x)=x3+23g(x)=x3+23g−1(x)=3x−2
Now, be careful with the notation for inverses. The “-1” is NOT an exponent despite the fact that is sure does look like one! When dealing with inverse functions we’ve got to remember that
f−1(x)≠1f(x)f−1(x)≠1f(x)
This is one of the more common mistakes that students make when first studying inverse functions.
The process for finding the inverse of a function is a fairly simple one although there is a couple of steps that can on occasion be somewhat messy. Here is the process
That’s the process. Most of the steps are not all that bad but as mentioned in the process there are a couple of steps that we really need to be careful with.
In the verification step we technically really do need to check that both (f∘f−1)(x)=x(f∘f−1)(x)=x and (f−1∘f)(x)=x(f−1∘f)(x)=x are true. For all the functions that we are going to be looking at in this section if one is true then the other will also be true. However, there are functions (they are far beyond the scope of this course however) for which it is possible for only of these to be true. This is brought up because in all the problems here we will be just checking one of them. We just need to always remember that technically we should check both.
There is one final topic that we need to address quickly before we leave this section. There is an interesting relationship between the graph of a function and its inverse.
Here is the graph of the function and inverse from the first two examples. We’ll not deal with the final example since that is a function that we haven’t really talked about graphing yet.
In both cases we can see that the graph of the inverse is a reflection of the actual function about the line y=xy=x. This will always be the case with the graphs of a function and its inverse.

Amy cut 32 ft of chain into pieces that were each 1/4 ft long. How many of these did Amy have after cutting the chain?
128 pieces can be made after cutting the chain
Solution:
Given that, Amy cut 32 ft of chain into pieces that were each 1/4 ft long
To find: Number of pieces after cutting the chain
From given,
[tex]\text{Total length of chain } = 32 \text{ feet }\\\\\text{Length of 1 piece } = \frac{1}{4} \text{ feet }[/tex]
Thus the number of pieces after cutting the chain can be found by dividing the total length of chain by length of 1 piece
[tex]\text{Number of pieces} = \frac{\text{Total length of chain}}{\text{Length of 1 piece }}[/tex]
Substituting the values, we get
[tex]\text{Number of pieces} = \frac{32}{\frac{1}{4}}\\\\\text{Number of pieces} = 32 \times 4 = 128[/tex]
Thus 128 pieces can be made after cutting the chain
Answer:

A train leaves a station and travels north at a speed of 45 mph. Two hours later, a second train leaves on a parallel track and travels north at 75 mph. How far from the station will they meet?
Both trains will meet in 3 hours.
Step-by-step explanation:
Given,
Speed of train A = 45 mph
Distance covered in two hours = 2*45 = 90 miles
Let,
x be the number of hours for both trains.
A(x) = 45x+90
Speed of train B = 75 mph
B(x) = 75x
For same distance;
A(x) = B(x)
[tex]45x+90=75x\\90=75x-45x\\90=30x\\30x=90[/tex]
Dividing both sides by 30
[tex]\frac{30x}{30}=\frac{90}{30}\\x=3[/tex]
Both trains will meet in 3 hours.

Mrs. Lin is sewing costumes for her grandchildren. She is making 3 lion costumes, 1 zebra costume, and 2 bear costumes. Fabric costs $7.49 per yard. How much fabric does Mrs. Lin need?
Answer:
rtetrt343444
Step-by-step explanation:
rewrew
Mrs. Lin needs a total of [tex]6 \frac{13}{24} \text{ yards}[/tex] yards of fabric for all the costumes.
To find out how much fabric Mrs. Lin needs for all the costumes, we need to calculate the total yardage required for each type of costume and then sum them up.
Given:
- Bear costume requires 2 1/4 yards.
- Lion costume requires 1 2/3 yards.
- Zebra costume requires 2 5/8 yards.
Let's calculate the total yardage required for each type of costume:
1. Bear costume:
[tex]\[ \text{Yardage for bear} = 2 \frac{1}{4} \text{ yards} \][/tex]
2. Lion costume:
[tex]\[ \text{Yardage for lion} = 1 \frac{2}{3} \text{ yards} \][/tex]
3. Zebra costume:
[tex]\[ \text{Yardage for zebra} = 2 \frac{5}{8} \text{ yards} \][/tex]
Now, let's convert all these mixed numbers into improper fractions:
1. Bear costume:
[tex]\[ \text{Yardage for bear} = 2 + \frac{1}{4} = \frac{8}{4} + \frac{1}{4} = \frac{9}{4} \text{ yards} \][/tex]
2. Lion costume:
[tex]\[ \text{Yardage for lion} = 1 + \frac{2}{3} = \frac{3}{3} + \frac{2}{3} = \frac{5}{3} \text{ yards} \][/tex]
3. Zebra costume:
[tex]\[ \text{Yardage for zebra} = 2 + \frac{5}{8} = \frac{16}{8} + \frac{5}{8} = \frac{21}{8} \text{ yards} \][/tex]
Now, let's sum up the yardages for all the costumes:
[tex]\[ \text{Total yardage} = \text{Yardage for bear} + \text{Yardage for lion} + \text{Yardage for zebra} \][/tex]
[tex]\[ \text{Total yardage} = \frac{9}{4} + \frac{5}{3} + \frac{21}{8} \text{ yards} \][/tex]
To add these fractions, we need to find a common denominator, which is 24:
[tex]\[ \text{Total yardage} = \frac{9 \times 6}{4 \times 6} + \frac{5 \times 8}{3 \times 8} + \frac{21 \times 3}{8 \times 3} \][/tex]
[tex]\[ \text{Total yardage} = \frac{54}{24} + \frac{40}{24} + \frac{63}{24} \][/tex]
Now, let's add the fractions:
[tex]\[ \text{Total yardage} = \frac{54 + 40 + 63}{24} \][/tex]
[tex]\[ \text{Total yardage} = \frac{157}{24} \][/tex]
Now, let's convert the improper fraction to a mixed number:
[tex]\[ \text{Total yardage} = 6 \frac{13}{24} \text{ yards} \][/tex]
So, Mrs. Lin needs a total of [tex]6 \frac{13}{24} \text{ yards}[/tex] yards of fabric for all the costumes.
complete question given below:
Mrs. Lin is sewing costumes for her grandchildren. She is making three lion costumes, one zebra costume, and two bear costumes. Fabric costs $7.49 per yard. How much fabric does Mrs. Lin need?
Bear= 2 1/4 yards
Lion= 1 2/3 yards
Zebra= 2 5/8 yards

if (x +5) -2(4x-1)=0 what is the value of x
Answer: x=1
Step-by-step explanation:
(X+5)-2(4x-1)=0
(-2•4x) (-2•-1)
X+5-8x+2=0
X-8x+5+2=0
(5+2)=7
X-8x=-7
-7x= -7
X=1
Simplifying the given expression (x +5) -2(4x-1)=0 we get the solution of this expression is x = 1.
A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.
The given expression,
(x +5) -2(4x-1)=0
Distributing the number inside the bracket we get,
x + 5 - 8x + 2 =0
Simplifying the like terms,
-7x + 7 = 0
Subtract 7 on both sides,
-7x = -7
Divide by -7 on both sides we get,
x = 1
Hence,
The solution of the expression is x = 1.

Find the perimeter and the area of the polygon with the given vertices. W (11,2), X (11,8), Y (14,8), Z (14,2)
Answer:
The perimeter of the polygon = 18 units
The area of the polygon will be [tex]A=18[/tex] square units
Step-by-step explanation:
Computing the Perimeter of the Polygon:
Considering the polygon with vertices
W (11,2)X (11,8)Y (14,8)Z (14,2)As the polygon is drawn in coordinate plane as shown in figure a.
From the attached figure a, we can observe that
The length of the side [tex]WZ = 3[/tex] unitsThe length of the side [tex]ZY = 6[/tex] unitsThe length of the side [tex]WX = 6[/tex] unitsThe length of the side [tex]XY = 3[/tex] unitsSo, the perimeter of the polygon can be calculated by taking the sum of the lengths of all sides i.e.
The perimeter of the polygon = [tex]WZ + ZY + WX + XY[/tex]
= 3 + 6 + 6 + 3
= 18 units
Computing the Area of the Polygon:
Area can be calculated by multiplying the length and width of the polygon.
[tex]A=lw[/tex]
So, the area will be:
[tex]A=lw[/tex]
[tex]A=(3)(6)[/tex]
[tex]A=18[/tex]
Therefore, the area of the polygon will be [tex]A=18[/tex] square units

Answer:
The solved given equation
[tex](\frac{x+2}{5})+(\frac{x+1}{3})=(\frac{x-3}{10})-2[/tex] is x=-7
Step-by-step explanation:
Given equation is [tex](\frac{x+2}{5})+(\frac{x+1}{3})=(\frac{x-3}{10})-2[/tex]
To solve the given equation as below :
[tex](\frac{x+2}{5})+(\frac{x+1}{3})=(\frac{x-3}{10})-2[/tex] ( by using the distributive property )
[tex]\frac{3x+6+5x+5}{15}=\frac{x-3-20}{10}[/tex] ( adding the like terms )
[tex]\frac{8x+11}{15}=\frac{x-23}{10}[/tex]
Multiply into (10(15) on both sides we get
[tex]\frac{8x+11}{15}\times (10)(15)=\frac{x-23}{10}\times (10)(15)[/tex]
[tex](8x+11)\times (10)=(x-23)\times (15)[/tex] ( by using the distributive property )
[tex]80x+110-15x+345=0[/tex] ( adding the like terms )
[tex]65x+455=0[/tex]
[tex]65x=-455[/tex]
[tex]x=-\frac{455}{65}[/tex]
Therefore x=-7
Therefore the solved given equation is x=-7

A typical traffic signal is programmed on a timer so that it is red 50% of the time, green 42% of the time, and yellow 8% of the time. The bulbs for each color are LED and are designed to last 100,000 hours. How many years does each color light last? Give your answer in years and months (rounded to the nearest month). What is the problem asking? What do we know? How did you solve the problem? Explain your steps.
Please answer this question for me
The problem is asking to identify how many years would each color light last. We know that a red light turns on 50% of the time, a green light is 42% of the time, and yellow is 8% of the time. Each light lasts 100,000 hours.
Although this question gives a lot of information, we really don't need the percentages of the lights. They simply are there to throw you off. Each light lasts 100,000 hours. We will use the following conversions:
1 day = 24 hours
1 year = 365 days
100,000 hours divided by 24 hours = 4166.67 days
4166.67 days divided by 365 days = 11.4 years (the 4 is 4 months).

They both have the same slope.
They have different y- intercepts.
They have no solution.
Please let me know, if I am right or wrong. I try my best to give correct answers
Answer:
A
Step-by-step explanation:
The standard equation is
y = mx + c
Where m is the slope and c is the y intercept
The 1st equation y = -2x + 1/4
Comparing with standard equation
the slope m = -2 and c = 1/4
The 2nd equation y = -2x - 1/4
Comparing with standard equation
the slope m = -2 and c = -1/4
To check if it as a solution
y = -2x + 1/4.......(1)
y = -2x - 1/4........(2)
Substracting (2) from (1)
y - y = -2x + 2x + 1/4 + 1/4
No solution since both x and y were eliminated
