What is a gradient in mathematics
gradient, in mathematics, a differential operator applied to a three-dimensional vector-valued function to yield a vector whose three components are the partial derivatives of the function with respect to its three variables. The symbol for gradient is ∇.
Electrical potential acting on an ion and driving it in one direction or another is the definition of an electrical gradient..
The migration of particles (solutes) from a region of higher concentration to a region of lower concentration, separated by a membrane, is referred to as a concentration gradient.
An ion can travel across a membrane depending on the concentration of a solute thanks to an electrochemical gradient, which combines an electrical gradient with a concentration gradient.

A Scatter plot is used for examining data with more than two variables, and it includes a different vertical axis for each variable.
What is the Scatter plot?The variables in the scatter plot made from the data are described by the independent variable, time, which is graphed along the horizontal axis. The independent variable will be time, and the dependent variable will be the number of calories provided.
When analyzing data with more than two variables, a scatter plot is used, which has a separate vertical axis for each variable.
Therefore, a scatter plot is used for examining data with more than two variables, and it includes a different vertical axis for each variable.

What is the short definition of a linear equation?
An algebraic equation of the form y=mx+b is referred to as a linear equation. m is the slope, and b is the y-intercept, and all that is involved is a constant and a first-order (linear) term. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."a) From the meaning of title -
f(t) = 3000t + 34000 { from 2020 it will be increase by 300 people

How to determine the recursive and the explicit functions?Recursive function
Here, we have
She decides she is going to take out half of what's left in there at the end of each month.
This means that
Tn = 1/2T(n - 1)
Hence, the recursive function is Tn = 1/2T(n - 1) where T1 = 300
Explicit function
Here, we have
Initial, T1 = 300
Rate, r = 1/2
The explicit function is represented as
Tn = T1 * r^(n-1)
So, we have
Tn = 300 * (1/2)^(n-1)
Hence, the explicit function is Tn = 300 * (1/2)^(n-1)

If a person with an hourly pay of $9.50 per hour gets a 20$ raise, what is the new hourly pay?
Percent formula, show your work
======================================================
Work Shown:
20% of $9.50 = 0.20*9.50 = 1.90
You earn an extra $1.90 on top of the $9.50 already there. So the new wage is 9.50 + 1.90 = 11.40 dollars per hour
-----------
Shortcut:
1.20*9.50 = 11.40
Think of 1.20 as 100% + 20% = 1 + 0.20 = 1.20, and this represents an increase of 20%
flip a coin will be flipped three times, and the number of heads recorded. explain why this is a binomial experiment. check all four required conditions.
When a coin will be flipped three times, and the number of heads recorded. The reason that, this is a binomial experiment is "there are a set number of trials, n. The coin would be flipped three times, a fixed number of times."
What is binomial experiment?A binomial experiment is one that has a fixed number of independent trials only with two outcomes. For instance, the outcome could be a yes or no response. When you toss a coin, you might wonder, "Will I get heads?" The response is either yes or even no.
That is the basic idea, but in order to label an experiment a binomial experiment, the following rules must be followed.
There must be a set number of trials. It should go without simply stating; if you don't have a set number of trials, you could keep tossing that coin indefinitely.Each trial is a separate event. "Independent" means that each time you duplicate the trial (i.e. tossing this same coin), it's a brand new trial with no effect on the outcome.Each trial is a separate event.

What is a number line?
A number line is a visual depiction of numbers on such a straight line created either horizontally or vertically. It is simple for humans to compare numbers and carry out simple arithmetic operations on those when they are written down on a number line. A number line is thought to begin at zero (0).For easy plotting on the number lines and for comparison of points, we will be converting all the fractions into decimals.

The dimensions of a square are altered so that one dimension is increased by 7 feet, while the other is decreased by 2 feet. The area of the resulting rectangle is 90 ft2. Find the original area of the square.
Answer:
64 ft^2
Step-by-step explanation:
It is a square to start, so each side = x
then (x+7 ) * ( x -2) = 90
x^2 + 5x -14 = 90
x^2 + 5x - 104 = 0 factor or use Quadratic Formula to fin x = 8 ft
Original area is then 8 x 8 = 64 ft^2

The amount of fruit in the smoothie will be 3/2 .
It is given in the question that a smoothie calls for 4/6 of a peach, 1/2 of a banana, and 2/6 of a kiwi.
We have to find the amount of fruit in the smoothie.
We know that,
Amount of fruit in the smoothie = Amount of peach in the smoothie + Amount of banana in the smoothie + Amount of kiwi in the smoothie
Hence,
Amount of fruit in the smoothie = 4/6 + 1/2 + 2/6
