The slope of ascent of the flight is 0.04
How to calculate the slope of ascent?From the question, we have the following parameters that can be used in our computation:
Typical cruising altitude = 38,000 feetInitial point of ascend = 4.3 miles at 4,200 feetAnother point of ascend = 167.5 miles at 36,700 feetThe above parameters can be represented as
(x, y) = (4.3, 4200) and (167.5, 36,700)
The slope is then calculated as
Slope = (y₂ - y₁)/(x₂ - x₁)
Where x and y are defined above
So, we have
Slope = (36700 - 4200)/(167.5 - 4.3)
Evaluate
Slope = 199.14 feet per mile
Recall that 5280 feet = 1 mile.
So, we have
Slope = 199.14 feet/5280 feet
Evaluate
Slope = 0.04
Hence, the required slope is 0.04

Does coordinates s or coordinate t represent a greater number in the following
parallelogram?
(-2,3)
(s, -1)
(0, -1)
(t, 3)
Thus, t has a greater value than s for the co-ordinates (s, -1) and (t, 3).
How to analyze points of an axis for a two dimensional entity?
We can use the fact that both points on the x-axis to compare the values of s and t for the provided parallelogram. As a result, each point that is closest to the x coordinate reflects a higher value than its equivalent counterparts.
Given, the co-ordinates of the parallelogram are: (-2, 3), (s, -1), (0, -1),
(t, 3).
Also, the co-ordinates of the parallelogram are also shown in the figure below.
To compare for the values of s and t for the given parallelogram,
we can analyze that both s and t represent points on the x-axis, therefore any point that stands rightmost with the x co-ordinate represents a higher value than the corresponding counterparts.
Therefore, t has a greater value than s for the co-ordinates (s, -1) and (t, 3), since t is on the right side from s.

Lexi opened her account with less money and accrues interest at a greater rate.
What is meant by interest?
In the fields of finance and economics, interest is the payment made at a set rate by a borrower or deposit-taking financial institution to a lender or depositor in excess of the principle amount (the amount borrowed). The charge that the borrower may be required to pay the lender or another entity is not the same as interest. Interest also differs from dividends, which are distributed by businesses to their shareholders from their profits or reserves, but not at a set rate but rather on a pro rata basis as a portion of the rewards received by risk-takers when revenue generated exceeds total expenditures. The amount of interest paid or received during a specific time period divided by the total amount borrowed or lent is the rate of interest.

Based on the calculations, the value of function g(f(x)) is equal to: g(f(x)) = x + 10.
What is a function?A function can be defined as a mathematical expression which is used to define and represent the relationship that exists between two or more variables. This ultimately implies that, a function is typically used for uniquely mapping an input variable (x-value) to an output variable (y-value).
In this exercise, you're required to determine the value of g(f(x)) and we are given the following functions:
f(x) = (x + 3)² ........function 1.
g(x) = √x + 7 ........function 2.
Next, we would substitute function 1 into function 2 as follows:
g(f(x)) = √((x + 3)²) + 7
g(f(x)) = (x + 3) + 7

What is odd and even numbers?Any integer that cannot be divided into twos is considered an odd number. Five computers, for instance, cannot be arranged in pairs only. 5 is therefore an odd number.
An even number is one that can be divided by two and leaves residue of zero. The even numbers include 2, 4, 6, 8, 10, and so on. Let's say, for instance, that you have ten chocolates. There are two groups of these chocolates that each include five chocolates. Ten is therefore an even number.
An even number is produced by adding two even numbers. In this case, 12 + 8 equals 20.
Odd numbers are created by adding odd numbers to even numbers. For example, 6 + 7 equals 13.
The outcome of adding two odd numbers is an even number. For an instance, 15 + 11 = 26.

Find the perimeter of a square with the sides of length 9x+11 and 13x-1
The perimeter of the square has a value of 260 units
How to determine the perimeter?From the question, the given parameters are
Shape = Square
Side lengths = 9x + 11 and 13x - 1
The side lengths of a square are congruent
This means that
9x + 11 = 13x - 1
Collect the like terms in the equation
So, we have
13x - 9x = 11 + 1
Evaluate the like terms
2x = 12
Divide both sides by 2
x = 6
The perimeter of the square is then calculated as
P = 4 * (9x + 11)
Where x = 6
So, we have
P = 4 * (9 x 6 + 11)
Evaluate
P = 260
Hence, the perimeter is 260 units

The value of a stock decreases by an average of 12 dollars each week. Which of the following represents the total average decrease in the stock after 4 weeks? |−12| − 4 = 8 dollars 4|−12| = 48 dollars |−12| − |4| = 8 dollars −4|12| = 48 dollars
The equation that represents the total average decrease in the stock after 4 weeks is 4|−12| = 48 dollars.
What is the total average decrease?When the value of a stock decreases, the number is a negative number. A negative number is a number that is less than zero. A negative number would have a negative sign in front of it. Thus, a $12 stock decrease would be written as -12.
The total stock decrease in 4 weeks can be determined by multiplying $-12 by 4 weeks. Multiplication is the operation that is used to determine the product of two or more numbers.
Total stock decrease = decrease per week x number of weeks

Hello I need help with a question if you are able to assist.
We are given an equation that represents the path of the longest shot put by the women's track team as:
[tex]h(x)=-0.017x^2\text{ + 1.08x + 5.8}[/tex]Where x represents the horizontal distance from the start and h(x) is the height of the shot put above the ground.
Solution:
(a) The vertex of the model:
Method 1: We can plot the model on a graph and identify the vertex from the graph. The vertex is the lowest/highest point on the curve.
The graph is shown below:
From the graph, we can see that the vertex of the model is : (31.765, 22.953)
Method 2: The vertex of the model can also be calculated using the formula:
First, we find the x-coordinate using the formula:
[tex]x\text{ = -}\frac{b}{2a}[/tex]Substituting, we have:
[tex]\begin{gathered} x\text{ = -}\frac{1.08}{2\text{ }\times\text{ -0.017}} \\ x\text{ = 31.765} \end{gathered}[/tex]The y-coordinate of the vertex can be obtained by substituting the x-coordinate into the model. So, we have the y-coordinate to be:
[tex]\begin{gathered} y\text{ = h(31.765)} \\ y=-0.017(31.765)^2\text{ + 1.08(31.765) + 5.8} \\ y\text{ = 22.953} \end{gathered}[/tex]Hence, the vertex is : (31.765, 22.953)
(b) The maximum height
The horizontal distance of the maximum height of the shot put from the starting point is :
From the plot, the starting point is -4.98
[tex]\begin{gathered} \text{Horizontal distance = 31.765 + 4.98} \\ =\text{ 36.745 f}eet \end{gathered}[/tex]The maximum height of the shot put is 22.953 feet, 36.745 feet away from the starting point.
(c) The vertical intercept
The vertical intercept is the point where the curve cuts the y-axis.
From the graph, the point is (0, 5.8).
At this point where the horizontal distance is 4.98 feet away from the starting point, the shot put is 5.8 feet above the ground.
(d) The distance from the starting point to when the shot-put stikes the ground is:
From the plot, the intercepts on the x-axis are (-4.98, 0) and (68.509, 0).
Hence, the distance is:
[tex]\begin{gathered} =\text{ 68.509 + 4.98} \\ =\text{ 73.489} \\ \cong\text{ 73.49 f}eet\text{ (2.d.p)} \end{gathered}[/tex]Evaluate (10 – 41) ÷ (5 + 1).
