Answer: Maximum height reached is 804.88 m
Step-by-step explanation:
At maximum height velocity is zero
We have equation of motion v² = u² + 2as
Initial velocity, u = 320 ft/s = 97.536 m/s
Final velocity, v = 0 m/s
Acceleration, a = -9.81 m/s²
Substituting
v² = u² + 2as
0² = 97.536² + 2 x -9.81 x s
s = 484.88 m
So the arrow further a height of 484.88 m
Total height = 320 + 484.88 = 804.88 m
Write an equation of a line that passes through the point (7, 3) and is parallel to the line y = negative 2 over 3 x + 3.
We are asked to determine the equation of a line that is parallel to:
[tex]y=-\frac{2}{3}x+3[/tex]Two lines are parallel if their slopes are in the following relationship:
[tex]m_2=-\frac{1}{m_1}[/tex]Therefore, if m1 is the slope of the given line and m2 is the slope of the parallel line we may determine the value of the slope of the parallel line by replacing it in the relationship. Let's remember that when a line is written in the form:
[tex]y=mx+b[/tex]Where "m" is the slope. Therefore, m1 is -2/3. Replacing in the relationship we get:
[tex]m_2=-\frac{1}{-\frac{2}{3}}=\frac{3}{2}[/tex]Now, we go back to the general form of a line equation and replace the value of the new slope:
[tex]y=\frac{3}{2}x+b[/tex]The value "b" is the y-intercept and can be found using the point through which the line passes:
[tex]3=\frac{3}{2}(7)+b[/tex]Now we solve the operations:
[tex]3=\frac{21}{2}+b[/tex]Subtracting 21/2 from both sides:
[tex]3-\frac{21}{2}=b[/tex]Solving the operations:
[tex]-\frac{15}{2}=b[/tex]Now we replace in the line equation:
[tex]y=\frac{3}{2}x-\frac{15}{2}[/tex]And thus we get the equation of the parallel line.

The centre of mass of 40g, (1,3); 30g, (2,-1); 70g, (0,0) and 50g (0,-2) is located at (10/19,-1/19).
The formula to find the coordinates (X,Y) of centre of mass of a discrete particles system is,
X = (m₁x₁+m₂x₂+m₃x₃+m₄x₄)/(m₁+m₂+m₃+m₄)
Y = (m₁y₁+m₂y₂+m₃y₃+m₄y₄)/(m₁+m₂+m₃+m₄)
As we know,
m = 40
m = 30
m = 70
m = 50
Putting all the values in the formula,
for X coordinate,
X = [(40×1)+(30×2)+(70×0)+(50×0)]/(40+30+70+50)
X =(40+60+0+0)/(190)
X = 100/190
X = 10/19
For Y coordinate,
Y = [(40×3)+(30×-1)+(70×0)+(50×-2)]/(40+30+70+50)
Y= (120-30+0-100)/(190)
Y = -10/190
Y = -1/19

1) Write an equation perpendicular to 2x + 3y = 18 that passes through the point (1, 5).
2) Write an equation parallel to y = 2x + 6 that passes through the point (0, 7).
The required equation for the line is y = x + 4 that perpendicular to y = -x + 4 and passes through the point (1, 5).
The required equation is y = 2x + 7 that parallel to y = -3x+7 passes through the point (0, 7).
What is the slope of the line?The slope of a line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
The equation of the line which is given as
2x + 3y = 18
3y = -2x + 18
y = -2x/3 + 6
Here the slope of the line, m = -1/3
Let the required line would be as
⇒ y₀ - y₁ = m₀ (x₀ - x₁ )
The required line passes through the point (1, 5)
Here x₁ = 1 and y₁ = 5 and m₀ = 1/3 (Since required line perpendicular)
The equation of the line is obtained by substituting these values into the above equation;
⇒ y - 5 = 1 (x - 1)
⇒ y = x - 1 + 5
⇒ y = x + 4
Therefore, the required equation for the line is y = x + 4 that perpendicular to y = -x + 4 and passes through the point (1, 5).
The equation of the line which is given as
y = 2x + 6
Here the slope of the line, m = 2
The given coordinates of the line;
points on the line (0, 7)
Let the required line would be as
⇒ y - y₁ = m (x - x₁ )
Here x₁ = 0 and y₁ = 7 and m = 2
The equation of the line is obtained by substituting these values into the above equation;
⇒ y - 7 = 2 (x - 0)
⇒ y - 7 = 2x
⇒ y = 2x + 7
Therefore, the required equation is y = 2x + 7 that parallel to y = -3x+7 passes through the point (0, 7).

The value of the set (A∪C)'∩B is {9 , 12} .
A subfield of mathematical logic called set theory examines sets, which are essentially collections of objects.
Set theory is a discipline of mathematics that largely addresses problems that are pertinent to mathematics as a whole, despite the fact that any kind of object can be constructed into a set.Set theory is founded on a simple binary relationship between an object o and a set A.It is written as o A if o is a part (or member) of A. Members of a set are enumerated with commas to denote separation when describing them, or a property of those parts is enclosed in braces.Sets can be associated by the membership relation since they are objects.The given sets are:
U ={1,2,3,4,5,6,7,8,9,10,11,12,13}
A = {3,7,11,13}
B = {3,6,9,12,13}
C = {2,3,5,6,7,8}
Now B' = {1,2,4,5,7,8,10,11}
b) B'∩C = {2,5,7,8,}
c) A∪C = {2,3,5,6,7,8,11,13}
(A∪C)' = {1,4,9,10,12}

Andrew has $9,000 in a savings account that earns 5% interest per year. How much will he have including interest in 1 year?
Andrew will have $9,450 in his savings account that earns 5% interest per year.
According to the question,
We have the following information:
Principal amount in Andrew's savings account = $9,000
Interest rate = 5% per year
Time = 1 year
We know that we use the following formula to find the simple interest on any amount:
Simple interest = (principal*rate*time)/100
Simple interest = (9000*1*5)/100
Simple interest = $450
Now, the total amount in his savings account will be the sum of the amount earned from the interest and the principal amount submitted by him.
Total amount = interest+principal
Total amount = 450+9000
Total amount = $9,450
Hence, he will have $9,450 in his savings account.

What is the down payment?The down payment is an upfront payment required to reduce the mortgage loan and assure the financier that the mortgagee is financially ready to engage in the mortgage transaction.
The price of a dream house = $239,000
Down payment = 20% = $47,800 ($239,000 x 20%)

We know that
• The earnings are $7,592.
,• The time is 16 years.
,• The annual interest rate is 9.04%.
This problem is about simple interest, its formula is

The commutative property of addition for three numbers is given by -
a + (b + c) = (a + b) + c
Given is the following expression -
1/4 + 1/3 + 3/4
We have the following expression -
1/4 + 1/3 + 3/4
Now, lets solve the expression by adding first two terms first and than add the third term to result of the addition of first two terms. Mathematically -
(1/4 + 1/3) + 3/4
Let (1/4 + 3/4) = K

The statement which best describes Mike's error is that: D) While the graph does pass through the origin, it is not a straight line.
What is a graph?A graph can be defined as a type of chart that's commonly used for the graphical representation of data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.
In Mathematics, the graph of any proportional relationship is characterized by a straight line with the points passing through the origin (0, 0) because as the values on the x-coordinate (x-axis) decreases or increases, the values on the y-coordinate (y-axis) decreases or increases simultaneously.
In this context, we can reasonably infer and logically deduce that even though Mike's graph passes through the origin, his error is that it is not a straight line.
