What is partial derivatives?Partial derivatives are a type of derivative in calculus that are used to measure the rate of change of a function with respect to a single independent variable, while holding the other variables constant. They are denoted with a symbol called a partial derivative operator, which is a curved d with a line over it. Partial derivatives are used to calculate derivatives in multivariable functions and to find the maximum or minimum points of a function. Partial derivatives can also be used to analyze the behavior of functions near a point, or to solve equations involving multiple variables.

A group of tourists are on a 3-day long trip. They hike 1/8 of the trail on the first day. On the second day, they hike 4/7 of the remaining distance. On the third day, they hike 1/3 of the remaining distance, plus the final 8 km. How many kilometers long is the trail?
Answer: 32 km (I believe)
Explanation: So, on the first day the tourists walked x/8 km.
Then the remaining distance after the first day is (x- x/8) = 7x/8 km.
On the second day, the tourists walked 4/7 of the REMAINING path, so now we multiply 4/7 by 7x/8 to get x/2 km.
So, the remaining path to travel after 2nd day is (7x/8-x/2) = 3x/8
Remember, on the third day they walked 1/3 of the remaining trail and the last 8 km.
So now, we do (3x/8 - 3x/8 x 1/3) = 8
Now, x/4 =8 ; to find x, we do 8 x 4 to get 32
So, our answer is 32

A system of two linear equations in two variables x and y is rewritten as the following augmented matrix:
[ 6 6 | -18 ]
[ -4 -2 | 2 ]
Use the Gauss-Jordan Elimination Method to solve for x and y.
x = _________
y = _________
Answer:
x = -10
y = 1
Step-by-step explanation:
To use the Gauss-Jordan Elimination Method to solve for x and y, we need to put the augmented matrix in row-echelon form. The first step is to eliminate the x-coefficient in the second row by adding 4 times the first row to the second row. This gives us the following matrix:
[ 6 6 | -18 ]
[ 0 -10 | -10 ]
Next, we need to eliminate the y-coefficient in the second row. We can do this by adding 5 times the second row to the first row, which gives us the following matrix:
[ 1 -10 | -10 ]
[ 0 -10 | -10 ]
Now, the matrix is already in row-echelon form, so we can read the solution directly from the matrix. The solution is x = -10 and y = 1. Therefore, the solutions to the system of linear equations are:
x = -10
y = 1
Note that there may be other solutions to the system of equations, depending on the specific equations that the matrix represents. The Gauss-Jordan Elimination Method will always give us one possible solution, but there may be other solutions as well.

As given in the question,
In the given triangle MPQ we have,
Sum of all the interior angles in the triangle is 180 degrees.
m ∠P + m ∠M + m∠1 =180°
⇒58° + 66° + m∠1=180°
⇒m∠1= 180° - ( 58° + 66°)
⇒m∠1=56°
From the figure , ∠1 and ∠2 are vertically opposite angles:
⇒m∠1= m∠2
⇒m∠2=56°.
In triangle QNO we have,
m ∠O + m∠2 + m∠3 =180°

What is function?A function is defined as a relation between a set of inputs having one output each.
Given that, A marine biologist is studying the growth of a particular species of fish when the marine biologist concluded her study, the length of the fish was approximately 9.19 cm
A) For m = 0
f(0) = 5(1.07)⁰ = 5 cm
The length of the fish was approximately 9.19 cm.

B) y-intercept of the graph of the function f(m) represent initial length of fish = 5 cm
C) average rate of change of the function f(m) from m = 1 to m = 9
For m = 1
f(1) = 5(1.07) = 5.35 cm
For m = 9

Given that, a ship is sailing due north. At a certain point the bearing of a lighthouse is N39.8˚E and the distance is 11.5.
P is the ship, R is the light house and Q is the bearing.
PR is the distance between the ship and the light house, PR = 11.5

The median of a discrete random variable is the smallest value for which the cumulative probability equals or exceeds 0.5.
The median can be calculated by ordering the possible values of the random variable from smallest to largest and then finding the value for which the cumulative probability equals or exceeds 0.5.
Firstly, list out all the possible values of the random variable.Secondly, order the values from smallest to largest. Thirdly, calculate the cumulative probability for each value. Fourthly, find the value for which the cumulative probability equals or exceeds 0.5 Finally, this value is the median of the discrete random variable.The median of a discrete random variable can be found by arranging the possible values of the random variable from smallest to largest, and then calculating the cumulative probability for each value. Once the cumulative probability reaches or exceeds 0.5, the corresponding value of the random variable is the median.
Let the random variable X have values {1, 2, 3, 4, 5}.
Ordered from smallest to largest, X has the values {1, 2, 3, 4, 5}.
The cumulative probability for each value of X is calculated as follows:
P(X ≤ 1) = 0
P(X ≤ 2) = 0.2
P(X ≤ 3) = 0.6
P(X ≤ 4) = 0.9
P(X ≤ 5) = 1
The median of X is 3, since it is the smallest value for which the cumulative probability equals or exceeds 0.5.

If a linear regression equation predicts more than 25% of the variance in the Y scores, then the correlation between X and Y must be greater than (c) r = 0.35.
Correlation (r) quantifies the strength and direction of the linear relationship between two variables. A correlation of 0.35 indicates a moderate positive linear association, suggesting that as X increases, Y tends to increase as well, and vice versa.
When the correlation surpasses this threshold, it implies that a substantial portion of the variability in Y can be explained by changes in X. However, it's important to interpret the correlation value within the context of the specific data and the field of study.
Other factors like sample size and potential outliers can also influence the significance of the correlation. In summary, a correlation greater than (c) 0.35 signifies a meaningful connection between X and Y, contributing to the prediction of Y scores using the linear regression equation.

A spherical balloon is inflated so that its volume is increasing at the rate of 3 cubic feet per minute. How fast is the radius of the balloon increasing when the radius is 2 feet?
The rate at which the spherical balloon's radius is increasing is
3/16π ft/min when the volume is increasing at the rate of 3 ft³/min.
Given, a spherical balloon is inflated so that its volume is increasing at the rate of 3 cubic feet per minute.
we have to find that how fast is the radius of the balloon increasing when the radius is 2 feet.
as, we know the volume of the balloon be,
V = 4/3πr³
now we have to find the rate of change of radius,
On differentiating both the sides with respect to time, we get
V' = 4/3π(3r²)dr/dt
V' = 4πr²dr/dt
as, the rate of change of volume of the balloon be, 3 ft³/min
V' = 3
3 = 4πr²dr/dt
dr/dt = 3/4πr²
Now, on putting r = 2, we get
dr/dt = 3/4π(2)²
dr/dt = 3/16π
so, the radius of the balloon increase at the rate of 3/16π.
Hence, the radius of the balloon increase at the rate of 3/16π.

What would be the net annual cost of the following checking accounts? a. Monthly fee, $2.50: processing fee, 20 cents per check; checks written, an average of 18 a month.
On solving the provided question, we can say that net annual cost of the given account is 18
What is an equation?equation: a statement stating the equality of two expressions having variable- and/or number-filled expressions. Since equations are essentially questions, finding a way to answer them has spurred the development of mathematics.
Net annual cost is that monthly fee X 12 + fee per check X number of checks per month X 12
[tex]= ($3.75 X 12) + ($0.25 X22 X 12)\\ = $111[/tex]
Net annual cost is service charges - Interest earnings
[tex]= ($15 X 3) - (0.06 X $600 X 9 / 12)= $18[/tex]
