what is interest ?In mathematics, interest is the amount of money earned or payable on an original investment or loan. You can use either simple or compound interest. Simple interest is calculated as a percentage of the initial amount, whereas compound interest is calculated on the principal amount plus any previously earned interest. If you invest $100 at a 5% annual simple interest rate, you will get $5 in interest every year for three years, for a total of $15.
Mika's account balance after 6 months would be $1413.33 ($1400 + $14.67 interest generated). His account balance after two years would be $1456 ($1400 + $56 interest earned).

A scientist is studying the growth of a particular species of plant. He writes the following equation to show the height of the plant f(n), in cm, after n days:
f(n) = 12(1.03)n
Part A: When the scientist concluded his study, the height of the plant was approximately 16.13 cm. What is a reasonable domain to plot the growth function? (4 points)
Part B: What does the y-intercept of the graph of the function f(n) represent? (2 points)
Part C: What is the average rate of change of the function f(n) from n = 3 to n = 10, and what does it represent? (4 points)
(10 points)
The required answers are Part A: Domain: {n | n is a positive integer}, Part B: 12, Part C: 0.98 cm/day.
How to deal exponential function?Part A:
To plot the growth function f(n), we need to consider a reasonable domain that includes all relevant values of n. Since we are dealing with the growth of a plant, the domain should only include positive integers, as it does not make sense to talk about fractional or negative days. Therefore, a reasonable domain to plot the growth function would be:
Domain: {n | n is a positive integer}
Part B:
The y-intercept of the graph of the function f(n) is the value of f(0), which can be found by substituting n = 0 into the equation:
[tex]$f(0) = 12(1.03)^0 = 12(1) = 12[/tex]
Therefore, the y-intercept of the graph represents the initial height of the plant, which is 12 cm.
Part C:
The average rate of change of the function f(n) from n = 3 to n = 10 can be found using the formula:
Average rate of change = (f(10) - f(3))/(10 - 3)
We can evaluate f(10) and f(3) using the given equation:
f(10) = 12(1.03)^10 ≈ 18.27
f(3) = 12(1.03)^3 ≈ 13.41
Substituting these values into the formula, we get:
[tex]$Average rate change=\frac{(f(10) - f(3))}{10-3} \approx0.98[/tex]
Therefore, the average rate of change of the function f(n) from n = 3 to n = 10 is approximately 0.98 cm/day. This represents the average daily growth rate of the plant during this period.

Therefore , the solution of the given problem of angles comes out to be lim x→2 g(x) = lim x→2 [(x² - 4)/(x - 2)] = 4.
What does an angle mean?Both the largest and the tiniest walls of a skew are determined by an intersection of the lines that connect that make up its ends. A junction could possibly bring two routes together. Another result of two objects interacting is an angle. They most closely resemble dihedral shapes. Two line beams can be arranged in a variety of ways between their extremities to form a two-dimensional curve.
Here,
The abbreviated formula for f(x) = (4x³ - 3x² - 10x - 3)/(x³ - x² - 6x) is as follows:
f(x) = (4x³ - 3x² - 10x - 3)/(x³ - x² - 6x)
f(x) = [(4x³ - 12x) + (9x² - 3)] / (x(x² - x - 6))
f(x) = [4x(x² - 3) + 3(3x² - 1)] / [x(x - 3)(x + 2)]
f(x) = [4x/(x-3)] + [3/(x+2)] - [3x/(x²-x-6)]
Consequently, the abbreviated form is:
f(x) = [4x/(x-3)] + [3/(x+2)] - [3x/(x²-x-6)]
Direct substitution can be used to find the limit of the equation g(x) = (x2 - 4)/(x - 2) as x approaches 2, which results in the undetermined form 0/0. In order to take the derivative of the numerator and denominator with regard to x, we can apply L'Hopital's rule as follows:
g(x) = (x² - 4)/(x - 2)
g'(x) = [(2x) * (x - 2) - (x² - 4) * 1] / (x - 2)²
g'(2) = 4
As x gets closer to 2, the maximum of g(x) is as follows:
lim x→2 g(x) = lim x→2 [(x² - 4)/(x - 2)] = 4

Step-by-step explanation:
First write down the whole inequality:
1 - 3x ≤ -2 ﹤ 3x + 5
Then it can be seen that there are two separate inequalities here, so we have a system of inequalities:

Leslie’s brother weighs 16.7 kg. Leslie weighs 12.4 kg. Leslie’s dad
weighs 67.6 kg. How much heavier is Leslie’s dad than the two
children together?
Leslie's dad is 38.5 kg heavier than the combined weight of Leslie and her brother.
To solve the problem, we first need to find the total weight of the two children together, and then subtract that from the weight of Leslie's dad:
Total weight of the two children = Leslie's weight + her brother's weight
Total weight of the two children = 12.4 kg + 16.7 kg
Total weight of the two children = 29.1 kg
Weight difference between Leslie's dad and the two children = Leslie's dad's weight - Total weight of the two children
Weight difference between Leslie's dad and the two children = 67.6 kg - 29.1 kg
Weight difference between Leslie's dad and the two children = 38.5 kg
Therefore, Leslie's dad is 38.5 kg heavier than the two children combined.

5/18 + 2/12
A) 1/2
B) 4/9
C) 8/18
D)7/30
Answer:
B. 4/9
Step-by-step explanation:
We can simplify the given expression by finding a common denominator for 18 and 12. The least common multiple of 18 and 12 is 36.
Multiplying the first fraction 5/18 by 2/2 (which equals 1) to get a denominator of 36:
5/18 = 5/18 x 2/2 = 10/36
Multiplying the second fraction 2/12 by 3/3 (which equals 1) to get a denominator of 36:
2/12 = 2/12 x 3/3 = 6/36
Now we can add the two fractions with the same denominator:
10/36 + 6/36 = 16/36
We can simplify this fraction by dividing the numerator and denominator by their greatest common factor, which is 4:
16/36 = 4/9
Therefore, the solution is B) 4/9.
Answer:
the answer for the question is b) 4/9
the waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed between 0 and 6 minutes. find the probability that a randomly selected passenger has a waiting time greater than 4.25 minutes.
The probability of a person being randomly choosing having waiting time greater than 4.25 is 0.2917 or 29.17%.
To answer this question we need to know about-
Probability is the measure of the likelihood of an event to happen. The probability value ranges between 0 and 1.
When the probability value is 0, it means that the event is impossible to happen.
When the probability value is 1, it means that the event is certain to happen.
Uniform distribution is when the values of a probability distribution are spread uniformly across the interval, it is called a Uniform distribution
The waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed between 0 and 6 minutes.
The probability that a randomly selected passenger has a waiting time greater than 4.25 minutes is found as follows:
Let X = Waiting time of a randomly selected passenger P(X > 4.25) = ?
Now we have to use the uniform distribution formula to find the probability:
P(C< X >D)=C-D/B-A
where C = lower value of the selected interval
D= upper value of the selected interval
B= highest value of the selected interval
A= lowest value of the selected interval
putting above values in the formula -
P(X > 4.25) = 6 - 4.25/6-0= 0.2917
Hence the probability that a randomly selected passenger has a waiting time greater than 4.25 minutes is 0.2917.

A manufacturer of graphing calculators has determined that 11,000 calculators per week will be sold at a price of $98. At a price of $93, it is estimated that 13,150 calculators would be sold.
(a) Determine a linear function that will predict the number of calculators y that would be sold at a given price x.
(b) Use this model to predict the number of calculators that would be sold each week at a price of $73.
a: ______ b:______
Answer:
(a) To determine the linear function that predicts the number of calculators sold at a given price, we need to find the equation of the line that passes through the points (98, 11,000) and (93, 13,150).First, we can find the slope of the line using the formula:slope = (change in y) / (change in x)slope = (13,150 - 11,000) / (93 - 98)slope = -430 per 1 dollar decrease in price(Note that we can interpret the negative slope as an inverse relationship between price and quantity demanded. As price decreases, the quantity demanded increases.)Next, we can use the point-slope form of a line to find the equation of the line:y - y1 = m(x - x1)where y1 = 11,000, x1 = 98, and m = -430.y - 11,000 = -430(x - 98)Simplifying and solving for y, we get:y = -430x + 51,340Therefore, the linear function that predicts the number of calculators sold at a given price is:y = -430x + 51,340(b) To predict the number of calculators that would be sold each week at a price of $73, we can substitute x = 73 into the linear function we found in part (a):y = -430(73) + 51,340y = 18,140Therefore, we predict that 18,140 calculators would be sold each week at a price of $73.

What is a quadratic equation?Any equation of the form [tex]\rm ax\²+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
To find the zeros, we need to solve the equation f(x) = 0. We can use the quadratic formula for this, which is given by:
x = (-b ± √(b² - 4ac)) / 2a
where a, b, and c are the coefficients of the quadratic equation ax² + bx + c.
[tex]x = (-(-21) \pm \sqrt{((-21)^2 - 4(3)(18))) / 2(3)}\\\\x = (21 \pm\sqrt{(441 - 216)) / 6}\\\\x = (21 \pm\sqrt{(225)) / 6}\\\\x_1 = 1 \ \rm and \ x_2 = 6[/tex]
Therefore, the zeros of the function f(x) are x₁ = 1 and x₂ = 6.
To find the x-intercepts, we need to plot the graph of the function and look for the points where the graph intersects the x-axis. We can start by plotting a few points to get a rough idea of the shape of the graph:
When x = 0, f(x) = 1
When x = 1, f(x) = 0
When x = 2, f(x) = 0

Anastasia has a part-time job and earns the same amount of money each week. She decided to deposit all her
weekly earnings in a savings account, which originally had $225. After making deposits for 11 weeks, she
had $665 in her account. How much money will be in her account after 24 weeks? Show how you arrived at
your answer.
We can start by finding how much money Anastasia saves each week.
The difference between her starting balance and ending balance after 11 weeks is:
$665 - $225 = $440
So, over 11 weeks, Anastasia has saved a total of $440.
To find how much money she saves each week, we can divide the total savings by the number of weeks:
$440 ÷ 11 weeks = $40 per week
This means that Anastasia saves $40 each week.
To find out how much money she will have in her account after 24 weeks, we can multiply the amount she saves each week by the number of weeks:
$40 per week × 24 weeks = $960
Therefore, after 24 weeks, Anastasia will have $960 in her savings account.

Find an equation following defining the following function and state the domain of the function.
The value of the addition of the two composite function is (x - 6) + √(x + 7).
What are functions?A function in mathematics is a relationship between a set of possible outputs (the range) and a set of inputs (the domain), with the assets that each input is connected to exactly one output. By carrying out operations like addition, subtraction, multiplication, division, and composition with other functions, functions can be changed. By summing the results of the two functions f(x) and g(x), we may add them. In a similar manner, we may combine two functions, f(x) and g(x), by inserting the output of g(x) into f(x).
Given that f(x) = x - 6 and g(x) = √(x + 7).
The composite function (f + g)(x) is given as:
(f + g)(x) = f(x) + g(x)
= (x - 6) + √(x + 7)

Mackenzie just started training for a marathon. According to her plan, she must run 19 miles the first week and 25 miles the second week. What is the percent increase?
the percent increase from running 19 miles in the first week to 25 miles in the second week is 31.58%. This means that Mackenzie increased her mileage by 31.58% from the first week to the second week.
To calculate the percent increase from running 19 miles in the first week to 25 miles in the second week, we first need to find the difference between the two numbers.
The difference is calculated as follows:
25 - 19 = 6
So, the difference between the two weeks is 6 miles.
To find the percent increase, we need to divide the difference by the original value and then multiply by 100.
The formula for percent increase is:
(percent increase) = [(new value - old value) / old value] x 100%
Using this formula, we can find the percent increase in Mackenzie's training as follows:
(percent increase) = [(25 - 19) / 19] x 100%
(percent increase) = (6 / 19) x 100%
(percent increase) = 0.3158 x 100%
