Zeke claims that the function to the left should have three shaded regions for its range because it is a three-piece piecewise function. Is Zeke correct? Yes or No
Answers
Answer:
No
Step-by-step explanation:
The input to a function which is the domain of the function is the x-variable or independent variable, while the output of a function which is the range of the function is the y-variable or dependent variable
In the given function, the outputs or the ranges of the function for the input of piece with x-values -3 ≤ x ≤ -8 completely overlaps the ranges for the piece with x-values 1 < x ≤ 3, therefore, both ranges can be represented by a single shaded region, giving a total of two shaded regions.
The function on the left of the graph should have two shaded regions for its range because the range of the two functions overlaps. Therefore, no the claim of Zeke is incorrect.
Given :
The graph shows the piece-wise function.
The following steps can be used to determine that the Zeke claims is correct or not:
Step 1 - The domain of the graph of the function present in the third and fourth quadrant is:
[tex]-8\leq x \leq -3[/tex]
Step 2 - The domain of the graph of the function present in the second quadrant is:
[tex]-2< x < -1[/tex]
Step 3 - The domain of the graph of the function present in the first quadrant is:
[tex]1< x\leq 3[/tex]
The function on the left of the graph should have two shaded regions for its range because the range of the two functions overlaps. Therefore, no the claim of Zeke is incorrect.

A student found the volume of a rectangular pyramid with a base area of 92 square meters and a height of 54 meters to be 4,968 cubic meters. Explain and correct the answer.
Answers
1 656 m³
Step-by-step explanation:The volume of a rectangular pyramid formulaV = B×h/3
= 92m²×54m/3
= 92m²×18m
= 1 656 m³Answer:
v = 1656 cubic meters
Step-by-step explanation:
what we have = base area = 92 square meters
= height = 54 meters
the volume formula of a rectangular pyramid = V=lwh /3
since base area = lw
lw = 92 meters
now we can write - 92* 54 /3
= 4968 /3
= 1656
So the corect answer is 1656 cubic meters and the student is wrong.

Brand X copier advertises that its copiers run 24% longer between service calls than its competitor. If Brand X copiers run 59,800 copies between services, how many copies would the competitor run?
Answers
Answer:
The competitor will run 48,225.81 copies.
Step-by-step explanation:
Brand x copier run 59,800 copies between services
Brand X copiers run 24% longer between service calls than its competitor.
Let x = copies run by the competitor between services
Number of copies the competitor will run is
24% of x + x = 59,800
0.24x + x = 59,800
1.24x = 59,800
x= 59,800 / 1.24
x = 48,225.81
Therefore, the competitor will run 48,225.81 copies.

how do you convert a percent to a fraction?
Answers
Answer:
Step 1: Write down the percent divided by 100 like this: [tex]\frac{percent}{100}[/tex]
Step 2: If the percent is not a whole number, then multiply both top and bottom by 10 for every number after the decimal point. (For example, if there is one number after the decimal, then use 10, if there are two then use 100, etc.)
Step 3: Simplify (or reduce) the fraction
Step-by-step explanation:
Example:
Step 1: Write down:
[tex]\frac{11}{100}[/tex]
Step 2: The percent is a whole number, go straight to step 3.
Step 3: The fraction cannot be simplified further.
Answer:
To convert the percent into a fraction, divide it by 100 and remove the % symbol. Then, multiply the fraction to its lowest term.
For example:
[tex] \sf{12 \: \% \: = \frac{12}{100} = \frac{3}{25} } \: [/tex]
[tex] \sf{65\% \: = \frac{65}{100} = \frac{13}{20} }[/tex]
[tex] \underline{ \sf{some \: facts \: about \: percentage}}[/tex]
[tex] \star[/tex] Percentage are fractions whose denominators are 100
[tex] \star[/tex] A fraction can be expressed as a percentage by converting it into an equivalent fraction with 100 as a denominator.
[tex] \star [/tex] We can convert a fraction to a percent by multiplying it by 100 and the % symbol.
[tex] \star[/tex] A fraction with denominator 100 can be written as a percentage by writing the numerator with the % symbol.
[tex] \star[/tex] To convert a percentage to a decimal , divide it with 100 i.e move the decimal the places to the left.
[tex] \star[/tex] To convert a percentage to a fraction , divide it by 100 and reduce it to the lowest term.

Miranda wants to join Kick Start Gym and they have two plans she can choose from. Plan A will cost $12 per month plus a $130 joining fee. Plan B does not have a joining fee, but will cost $25 per month. Write and solve an equation to find the number of months for which the cost of each plan is equal.
Answers
Answer: 10
Step-by-step explanation:
Cost of any plan = Joining fee + (Per month fee ) × (number of months )
Let x be the number of months for which the cost of each plan is equal.
Cost of plan A = 130 + 12 x
Cost of plan B = 0+ 25x = 25x
According to the question,
[tex]25x = 130+12x\\\\\Rightarrow 25x-12x=130\\\\\Rightarrow\ 13x=130\\\\\Rightarrow\ x=\dfrac{130}{13}\\\\\Rightarrow\ x=10[/tex]
Hence, the number of months for which the cost of each plan is equal is 10.
