Equation for the perpendicular bisector of the line segment is
2y = 3x +20.
A line segment that bisects another line segment at a 90° angle is known as a perpendicular bisector.
What is perpendicular bisector?A line segment that bisects another line segment at a 90° angle is known as a perpendicular bisector. In other terms, a perpendicular bisector separates a line segment into two equal halves by intersecting it at a 90° angle.
Given coordinates of the endpoints of a line segment (-9, 3) and (-3,-1).
In order to find the equation of perpendicular line, we need to find the slope between given coordinates.
Slope between (-9, 3) and (-3, -1). :
slope = [tex]\frac{-1-3}{-3+9} =\frac{-2}{3}[/tex]
Slope of the perpendicular line is reciprocal and opposite in sign.
Therefore, slope of the perpendicular line = 3/2
Now, we need to find the midpoint of the given coordinates.
[tex]Mid points : \\x= \frac{ -9-3}{2} =-6\\ y= \frac{3-1}{2} = 1\\ pint = (-6,1)[/tex]
Let us apply point-slope form of the linear equation:

y - 1 = 3/2 (x + 6)

1. Amy is practicing target shooting at a special facility. A target projectile is launched
into the air from a platform 10 feet above the ground at a rate of 96 feet per second.
Amy aims and shoots at her target. Her bullet follows a linear path with a slope of 17
feet per second and she fires from a height of 5 feet.
The equation used to determine height and time is y = 16x² + 96x + 10 and y = 17x + 5
What is Projectile Motion ?
A projectile is something that has only one force acting on it the entire time, which is gravity, with the exception of the beginning.There are numerous types of projectiles.A projectile is something that is launched from the position of rest.A projectile is also any object that is hurled vertically upward as long as air resistance has no effect. Additionally, a projectile is any object that is fired upward at an angle to a horizontal plane.
The height of projectile after t seconds is given,
h(t) = 1/2 gt² + v₀t + s₀
where,
v₀ ( initial velocity ) = 96 feet per second
s₀ ( initial height ) = 10 feet
g = 32 feet per second²
put the values,
h(t) = 1/2 (32)t² + 96 t + 10
h(t) = 16 t² + 96 t + 10
so, let h(t) = y and t = x
y = 16x² + 96x + 10
We know, Amy's bullet follows a linear path,
The linear equation is,
y = mx + b
where, slope (m) = 17 feet per second and,
y-intercept (b) = 5 feet
plug in the values in linear equation,
y = 17x + 5
Therefore, The equation used to determine height and time is y = 16x² + 96x + 10 and y = 17x + 5

What is simple interest?
The principal of a loan or the first deposit into a savings account serves as the basis for simple interest. Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay further interest on the interest that has already accrued.
P=$26,000 r=2.6%=0.026
A=2P=2(26,000)=$52,000
A=P+Prt

Simple interest is defined as the percentage of earnings on the lending for a period of time
Here,
Value of a single bond = $160,000
Issue price of bond = $165, 386
Rate of interest = 9%
the market rate of interest = 8%
Interest payment = Semi-annually
Semi-annual interest payment = Value of the single bond × rate of interest/2

the graph of f(x)=x^3+3x^2-4 is shown. what is the value of f^-1(-4)
Since the function is not one-to-one, the inverse function of f(x) = x³ + 3x² - 4 is not defined at x = -4.
How to obtain the numeric value of the inverse function?An original function is composed by a set of points in the following format:
(x,y).
On the graph of the function, we have that:
The x-coordinate represents the input of the function, being the horizontal axis of the graph.The y-coordinate represents the output of the function, being the vertical axis of the graph.On the inverse function, the input and the output are exchanged, hence the format of the point is:
(y,x).
To find the numeric value of the inverse function at x = -4, we need to identify the value of x on the original function where y = -4.
However, looking at the graph of the function given at the end of the answer, the function is not one-to-one at y = -4, since f(-3) = f(0) = 4, thus the inverse function is not defined at x = -4.

When the students get reduced to 15 then each student will get 3 pens.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Total students = 25
Each Student get 2 pens.
So, 25 students get = 25 x 2= 50 pens
Now, number of children reduced = 25 -10= 15

for a given geometric sequence the seventh term is equal to 19/81 and the 12th term is equal to "-57" find the value of the 15th term
For the given geometric sequence the seventh term is equal to 19/81 and the 12th term is equal to "-57" the value of the 15th term is 1539.
What is a geometric sequence?
One particular sort of sequence is a geometric sequence. It is a sequence in which each term, with the exception of the first, is multiplied by a fixed integer to obtain the following term. The common ratio must be multiplied by the current term in the geometric sequence to obtain the next term, and the common ratio must be divided by the current term to obtain the previous term.
Solution Explained:
We know, a7 = 19/81, a12 = -57
So, ar^7 = 19/81 and ar^12 = -57 (r= common ratio)
Since r< a15 < 0 [the sign alternate]
Ignoring the signs,
r^12 = r^7 X r^5
57 = 19/81 X r^5
(57 X 81)/19 = r^5
243 = r^5
r = the fifth ratio of 243 = 3
therefore, r = -3
So, a15 = a12 X r^3
= -57 X (-3)^3
= 1539
Hence, the value of the 15th term is 1539.

The percent of change each year is 15%.
How to calculate percentage?
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
It is given that The number of carbon atoms in a fossil is given by the function y = [tex]51000(0.85)^t[/tex], where t represents the number of years since being discovered.
Here , y = [tex]51000(0.85)^t[/tex]
t = number of years
y = number of carbon atoms in a fossil.
For t = 1 year
y = 51000[tex](0.85)^1= 51000(0.85) = 43350[/tex]
For t = 2 years
y = 51000[tex](0.85)^2= 36847.5[/tex]
For t = 3 years
y = 51000[tex](0.85)^3=31320.375[/tex]
Percentage change in one year = [tex]\frac{36847.5-43350}{43350}[/tex] × 100 = -15%
Percentage change in second year = [tex]\frac{31320.375-36847.5}{36847.5}[/tex] × 100 = -15%
here, negative sign shows decrement. In this way, every year carbon atom in fossil decreases by 15%.
