On May 19, Bette Santoro borrowed $3,000 from Resse Bank at a rate of 12 1/2%. The loan is to be repaid on October 8. Assuming the loan is based on exact interest, what's the total interest cost to Bette?
The total interest cost to Bette is $145.89
What is exact interest basis?
Exact interest means that the interest is computed on 365-day per year basis rather than a 360-day per year basis, which is the case with financial institutions.
The first task in this case is to determine the number of days from May 19, when the amount was borrowed till October 8, when loan repayment was effected.
There are 142 days between the two dates, hence, we can compute exact interest on the loan as shown by the below formula:
exact interest=loan principal*number of days the borrowing last/365days *interest rate
loan principal=$3000
number of days the borrowing last=142
interest rate=12.5%(1/2%=0.5%)
Exact interest=$3000*142/365*12.5%
Exact interest=$145.89
The amount would have been different if ordinary interest where the number of days in a year is deemed to be 360, was used instead

In order to finance furniture for an office in a new retail store, Tools for Schools signs a 80-day simple discount note with a maturity value of $7700. Find the proceeds if the discount rate is 6%.
Based on the number of periods for the simple discount note to reach maturity and the discount rate, the proceeds are $7,598.74.
What are the proceeds?You can solve for the discounted price as:
= Maturity value x discount rate x number of periods
Solving gives:
= 7,700 x (6% / 365) x 80
= $101.26
The proceeds can then be found by subtracting the discounted price from the maturity price.
Solving for the proceeds gives:
= 7,700 - 101.26
= $7,598.74
Based on the simple discount note period, the maturity value, and the discount rate, the proceeds can be found to be $7,598.74.

Find two positive numbers whose difference is 9 and whose product is 2950.
The two positive numbers whose difference is 9 and whose product is 2950 are 50 and 59
How to determine the positive numbers?As a general rule, it should be noted that positive numbers are numbers that have their value greater than 0
So, we start by representing the two positive numbers with x and y.
So, we have the following equations
x - y = 9
xy = 2950
Make x the subject in the first equation x - y = 9
x = y + 9
Substitute y + 9 for x in the second equation
(y + 9) * y = 2950
Expand the equation
y^2 + 9y - 2950 = 0
Using a graphing tool, we have the solution of the above equation to be
y = 50
Recall that:
x = 9 + y
So, we have:
x = 9 + 50
Evaluate
x = 59
Hence, the two positive numbers whose difference is 9 and whose product is 2950 are 50 and 59

Answer:
Domain: All Real Numbers
Range: All Real Numbers
Step-by-step explanation:
So the domain of a function can be defined as an interval of x-values, which you can input into the function and get real numbers as an output. Since we have a cube root here, or more specifically an odd nth root, the domain is all real numbers, since cbrt(negative number) will just be a negative number since (negative number * negative number * negative number) = negative number, so there does exist a solution, unlike even nth roots like square root, which is restricted to only positive values inside the radical, otherwise you get non-real solutions.
Now let's look at the range of the function, which can be defined as an interval of y-values which can possibly be outputted by the function.
Since as mentioned before, the cube root isn't limited to a certain interval, and rather all real numbers, the range is also similar, since whenever you have a negative number in the radical, the output will be a negative number, so the range is all real numbers
The answer is A.
As any number can be inputted in place of x and the result, y, will be directly proportional to the inputting value, the domain and range of the function is All Real Numbers.
A television is identified by the diagonal measurement of the screen. A television has a length of 57-inches and a height of 33 inches. What is the length of the diagonal of the television screen?
Answer: 65.86 inches
Step-by-step explanation:
Length of the hypotenuse (length of diagonal) : a^2 + b^2 = c^2
The length (a)= 57
The height (b) =33
57^2= 3,249
33^3= 1,089
3,249 + 1,089 = c^2
4,338 = c^2
We next square root both sides to find c by itself (length of the diagonal)
[tex]\sqrt{4,338} = c[/tex]
c= 65.8634952...
You can then round to however many decimals are required.
To the hundreds place: 65.86 inches

Research suggests that students could benefit from later school starting times. A school administrative team is considering a proposal to move the starting time of the local schools one hour later than the current start time. To measure interest in the proposal, members of the team randomly select subjects attending a large high school soccer tournament played on the high school grounds on a Saturday morning. The team finds that 58% of those surveyed support a later high school start time. Which type of bias is most likely to be present in the survey results?
This is undercoverage bias because adults with older children are more likely to be included in the sample.
This is question wording bias because the phrasing of the later start times question may be confusing to some subjects.
This is nonresponse bias because some of those selected may choose to not provide their opinion on later start times.
This is voluntary response bias because vocal supporters of later start times will be more likely to offer their opinion.
The type of bias which is most likely to be present in the survey results is undercoverage bias because adults with older children are more likely to be included in the sample.

how many liters of 70% alcohol solution and 20% alcohol solution must be mixed to obtain 20 liters of 60% alcohol solution?
Answer:
16 liters of 70% alcohol
4 liters of 20% alcohol
Step-by-step explanation:
Let x = volume of 70% alcohol and y = volume of 20% alcohol. Since we need total of 20 liters, the first equation is x + y = 20. Next, calculate the amount of alcohol in the 20 liters of 60% alcohol. 60% is equivalent to 0.6, so there is 20*0.6 = 12 liters of alcohol in the 20 liter solution. Therefore the second equation is 0.7x + 0.2y = 12.
x + y = 20
0.7x + 0.2y = 12
2x + 2y = 40
7x + 2y = 120
-5x = -80
x = 16
16 + y = 20
y = 4

So, For this purpose,
We know that the Slope or gradient of a line is a number that describes both the direction and the steepness of the line.
And here
The slopes of two lines will only same when these lines are parallel.
In other words, Only parallel lines have a same slope.
So, if slope of one line is decreased by 20 degree then we have to kept these line parallel. Then we have to decrease the slope of other line by 30 degree also.
So, The slope of another line is changed to 20 degree to keep the segments parallel.

A population grows according to an exponential growth model. The initial population is Po = 19 and the growth rate is r = 0.4.
Then find an explicit formula for Pn
Then use the formula to find P11
P11 equals 769.417 and general formula is 19*(1.4)^(n)
Exponential growth is a process that increases quantity over time. It occurs when the instantaneous rate of change of a quantity with respect to time is proportional to the quantity itself
The growth rate is .4 per time period.
the exponential growth model is f = p * (1 + .4) ^ n
f is the future value.
p is the present value.
r is the growth rate per time period.
n is the number of time periods.
in p0, n = 0
in p11, n = 11
you are given that p0 = 19
in the formula, that becomes f = 19 * (1 + .4) ^ 0 = 19 * (1.4) ^ 0 = 19.
the formula for p1 becomes f = 19 * (1 + .4) ^ 1 = 19 * (1.4) ^ 1 = 26.6
the formula for p11 becomes f = 19 * (1 + .4) ^ 11 = 19 * (1.4) ^ 11 = 769.417
the formula for pn becomes = 19*(1.4)^(n)

What is a function?A function exists as a relation between a dependent variable (f(x)) and an expression of an independent variable (x), utilized to define the value of a dependent variable from a provided value of an independent variable.
We have been given a function,
[tex]$f(x)=\left \{ {{(1/2)^{x},x\leq 0 } \atop {2^x > 0}} \right.[/tex]
We have to estimate the value of f(x) when x = {-2, -1, 0, 1, 2}
If the values of x ≤ 0, take f(x) = (1/2)ˣ then
f(-2) = (1/2)⁻² = 2² = 4
f(-1) = (1/2)⁻¹ = 2¹ = 2
f(0) = (1/2)⁰ = 1
If the values of x > 0, take f(x) = 2ˣ then
f(1) = 2¹ = 2
f(2) = 2² = 4
The table exists as follows
x -2 -1 0 1 2

Every week, Suzie saves £5 and gets £3 from her Mum. Altogether, Suzie gets £8 every week. All we need to do is divide 56 by 8, which gives us 7. Suzie will take 7 weeks to collect enough money. To find out how much she has saved and been given by her mum individually, we need only times these values by 7. 5x7=35, and 3x7=21.
