A dry cleaner charges $5.00 to clean one item. He offers to clean a second item for $4.50, and a third for $4.00. If he continues to subtract $0.50 for each additional item, how much will it cost to clean six items?
MARKING BRAINLEST IF HURRY
Answer:$2.50 to clean 6 items
Step-by-step explanation:
$5.00-0.5=$4.5= 2 items
$4.5-0.5=$4= 3 items
$4-0.5=$3.5= 4 items
$3.5-0.5=$3= 5 items

Given f(x)=2^x and g(x)=f(x-3)+4, write the new function rule (equation) for function g and describe (using words*) the two transformations that occur between function f and function g.
Answer:
The first thing we do is find out what f(x-3) is[tex]f(x)=2^x\\f(x-3)=2^{x-3}[/tex] this is can be simplified using the rules of exponents[tex]f(x-3)=2^{x-3}\\f(x-3)=2^x\div2^3\\f(x-3)=\frac{2^{x}}{8}[/tex] Then we put that into g(x) [tex]g(x)=f(x-3)+4\\g(x)=\frac{2^{x}}{8}+4[/tex] The first transformation is at f(x), where it is divided by 8, and then inserted into g(x) which increases the new transformed f(x) by 4Jose earns $3680 per month, of which 22% is taken out of his paycheck for federal and state income taxes and other required deductions. Last month he spent $755 for rent and $86.12 for clothing. What percent of his take-home pay did he spend on rent and clothing combined?
Answer:
29.30%
Step-by-step explanation:
Total Monthly earnings of Jose = $3680
22% is paid for federal and state income taxes and other deductions.
Take-home salary for Jose is total earnings minus the taxes and deductions.
Take-home salary = $3680 - 22% of $3680
Take-home salary = $3680 - $809.6 = $2870.4
Money spent on rent = $755
Money spent on clothing = $86.12
Money spent on rent and clothing combined = $841.12
Percentage of a quantity is given as the quantity divided by the total quantity multiplied with 100.
Therefore,
Percentage of take-home pay spent on rent and clothing:
[tex]\dfrac{841.12}{2870.4}\times 100 = \bold{29.30\%}[/tex]

A chain of retail computer stores opened 2 stores in its first year of operation. After 8 years of operation, the chain consisted of 206 stores. If the number of stores opening per year is increasing at an exponential rate, identify the continuous rate of growth. Round k to the nearest hundredth. *
Answer:
0.66
Step-by-step explanation:
The exponential growth equation is expressed as;
S(t) = S0e^kt
S(t) is the number of stores after t years
S0 is the initial number of stores
If a chain of retail computer stores opened 2 stores in its first year of operation then at t = 1, S(t) = 2. Substitute into the equation;
2 = S0e^k(1)
2 = S0e^k .... 1
Also if after 8 years of operation, the chain consisted of 206 stores, this means at t = 8, S(t) = 206. Substitute into the equation;
206 = S0e^k(1)
206 = S0e^8k .... 2
Next is to calculate the value of k
Divide equation 2 by 1;
[tex]\frac{206}{2} = \frac{S0e^{8k} }{S0e^k }\\103 = e^{7k}\\apply \ ln \ to \ both \ sides\\ln103 = lne^{7k}\\ln103 = 7k\\k = \frac{ln103}{7}\\k = \frac{4.6347}{7} \\k = 0.6621[/tex]
Hence the value of k to the nearest hundredth is 0.66
