The function f : S--> T is not a one to one function
Given :
f : S --> T
S and T are finite sets with |S| > |T|
To proof : f is not one-one function
Let us assume for the sake of contradiction that f is one to one function
Let n and m be positive integers such that |S| = n and |T| = m.
Note that these integers need to exist as S and T are finite sets
n > m
Let S = {s1 , . . . , sn} and T = { t1 , . . . , tm}
Without loss of generality , we can assume that f(si) = ti , for i = 1, 2, 3 ....
as each element needs to have a unique image ( since , f is one to one ) and we can rename the element t1 , . . . , tm if the order of the elements didnt match up the images.
Since , n > m we have a term sm+1 while we do not have a term t m+1 .
This implies that sm+1 needs to have a same image as some sk
f(sm+1) = f(sk) = tk
However , f(sm+1) = f(sk) = tk is then in contradiction with the fact that f is one-to-one.
Since , we derive a contradiction our assumption that f is one-to-one is incorrect and thus f is not one-to-one

Use the formula A=P(1+r/n)ⁿt to solve the compound interest problem
Find how long it takes a $ 1700 investment to earn $ 500 interest if it is invested at 2 % interest compounded quarterly.
$ 500 interest will be earned in approximately years. (Round to the nearest tenth.)
The compound interest is 61.342 years.
What is compound interest?
Compound interest is the interest calculated on the principal and the interest accumulated over the previous period. It is different from simple interest, where interest is not added to the principal while calculating the interest during the next period.
To find the time period the interest must be compounded quarterly.
Calculated twelve times a year is interest that is compounded monthly. Interest is calculated on a quarterly compound basis, four times a year.
Given that;
A = 1700 P = 500
r = 2% n = 4
= 2/100
r = 0.02 /year
Using the formula A=P(1+r/n)ⁿt find the time period (t)
t = ln(A/P) / n[ln(1 + r/n)]
t = ln(1,700.00/500.00) / ( 4 × [ln(1 + 0.02/4)] )
t = ln(1,700.00/500.00) / ( 4 × [ln(1 + 0.005)] )

In 2010, a total of 2187 of the employees at Zoe's company owned a petrol car.
In 2013, there were 1029 employees with petrol cars.
The number of cars decreases exponentially,
As we know the formula for Exponential Decay, A = P (1 - r)^t
From the given data, a = 2187 and t = 3
The number of cars decreased = 2187 (1 - r)³
=> 2187 (1 - r)³ = 1029
=> (1 - r)³ = 1029/2187
=> (1 - r)³ = 343/729
=> (1 - r)³ = 7³/ 9³
=> 1 - r = 7/9
=> r = 1 - 7/9
=> r = 2/9
=> r = 0.2222
The Number of cars in 2017 i.e after 4 years from 2013

John paid $280 for a new mountain bicycle to sell in his shop. He wants to price it so that he can offer a 30% discount but still make 10% of the price he paid for it. At what price should the bike be marked?
By using the concept of discount, it can be calculated that
The bike should be marked at $440
What is discount?
Sometimes during sale, the items are sold at a reduced price from the original price of the item. The difference between the reduced price and the original price of the item is called discount.
Price paid by John for a new mountain bike = $280
Markup price = [tex]\frac{10}{100} \times 280[/tex] = $28
Price after markup = $(280 + 28) - $308
Let the marked price be $x
Rate of discount = 30%
Discount = [tex]\frac{30}{100}\times x[/tex]
Price after discount = [tex]x - \frac{30}{100}\times x[/tex]
= [tex]\frac{100x - 30x}{100}[/tex]

Suppose your gross monthly income is $6,500 and your current monthly payments are $525. If the
bank will allow you to pay up to 38% of your gross monthly income (less current monthly payments)
for a monthly house payment, what is the maximum loan you can obtain if the rate for a 25-year
mortgage is 8.65%?
The maximum loan you can obtain if the rate for a 25-year mortgage is 8.65% is $298,853.76
How to find monthly payment?A monthly payment can be calculated as;
Monthly payment = (Monthly income - payment)(percentage payment)
38% of your gross monthly income is
0.38 × $6,500 = $2470
If you're already spending $525 on monthly payments, the amount the bank says you can afford for a mortgage loan;
Then
$2470-525= $1945
The amortization formula can be used to find the corresponding loan value.
A = P(r/25)/(1 -(1 +r/25)^(-25t))
where A is the monthly payment on a loan of P at interest rate of r for time t years.
Filling in the known values, we have ;
1945= P(.0525/25)/(1 -(1 +.0525/25)^(-12·30))
≈ 0.00515636808·P

Principal Amount, P = $325Interest Rate, R = 4.75%Time, t = 9 yearsCompound interests are different from simple interest, and they are calculated using the following compound interest formula
CI = P(1 + R)^t - P
To calculate the amount, we have:
A = P + CI
So, the equation becomes

What is the hypotheses in research?A hypothesis states your predictions about what your research will find. It is a tentative answer to your research question that has not yet been tested. For some research projects, you might have to write several hypotheses that address different aspects of your research question.Hypotheses are used to support scientific research and create breakthroughs in knowledge. These brief statements are what form the basis of entire research experiments. Thus, a flaw in the formulation of a hypothesis may cause a flaw in the design of an entire experiment.a. two-tailed test
b. reject H0 if Z>1.96 or Z<-1.96
c. Z = 1.73
d. we have failed to reject the null hypothesis
e. P-value = 0.0418
We will use a Z test to resolve this, an it will be a two-tailed test because the hypothesis statements are not indicating a specific direction for the significant difference (H0 : μ1 = μ2 ; H1 : μ1 ≠ μ2), this also means that the significanclevel will be divided between the both tails (2.5% en each tail for the rejection regions). See attached drawing for reference.We need to find our critical value:
Zα/2 = Z(0.05/2) = 0.025
If we look for 0.025 in a Z table we will find that the critical value is 1.96 to the right, and by symmetry -1.96 to the left. So our decision rule will be to reject H0 if Z>1.96 or Z<-1.96The Z test will be done using the next equation:
Z = (x⁻1 - x⁻2) - (μ1 - μ2) / √( σ²1/n1 + σ²2/n2
Because we are testing the null hypothesis we know that μ1 - μ2 must be zero if they are supposed to be equal (H0 : μ1 = μ2), so we calculate as follows:Z = (100.5 - 98.8) - (0) / √( (3.4)²/38 + (5.8)²/51 = 1.7/0.9817 = 1.73
Z<1.96, therefore we have failed to reject the null hypothesis
The P-value for this test would be represented by the probability of Z being greater than 1.73, so we can look for it in any Z table, finding that its value is 0.0418, and because P-value>0.025 we again confirm that we don't have evidence statistically significant to reject the null hypothesis

Find the absolute extrema if they exist, as well as all values of x where they occur, for the function f(x)=(x²-64)^{1/11} on the domain [-8,9]
Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice.
A. The absolute maximum is , which occurs at x= (Round the absolute maximum to two decimal places as needed. Type an exact answer for the value of x where the maximum occurs. Use a comma to separate answers as needed.)
B. There is no absolute maximum.
The absolute maximum is 1.29, which occurs at x= 9
What is absolute extrema?
An absolute extremum of a perform in an exceedingly given interval is that the purpose at that a most or minimum worth of the perform is obtained. Frequently, the interval given is that the function's domain, and therefore the absolute extremum is that the purpose admire the most or minimum worth of the complete perform.
Main body:
Given =
f(x) = [tex](x^{2} -64)^{1/11[/tex]
f' (x) = derivative of function f(x)
f'(x) = 1/11[tex](x^{2} -64)^{-10/11[/tex] . 2x
= [tex]2 \frac{x}{11}[/tex][tex](x^{2} -64)^{-10/11[/tex]
putting f'(x) = 0
2x/11 [tex](x^{2} -64)^{-10/11[/tex] = 0
[tex](x^{2} -64)^{-10/11[/tex] = 0
[tex]x^{2} -64[/tex] = 0
x² = 64
x = ±8
We are given interval [-8,9].
Hence, calculating f(x) at -8, 8, 9.
f(-8) = 0
f(8) = 0
f(9) = [tex]17^{1/11}[/tex]
= 1.29
Hence, absolute maximum value is 1.29 at x=9.
