Answer:

ayden earns $6 an hour for raking leaves in the yard, so the equation representing the amount of money he can earn is:

Earnings = 6 * (Number of hours worked)Brooklynn earns $9 for making everyone's beds and an additional $1.50 an hour for helping with the laundry, so the equation representing the amount of money she can earn is:

Earnings = 9 + (1.5 * (Number of hours worked))To find how many hours each need to work in order to earn the same amount of money, we can set the two equations equal to each other and solve for the number of hours worked.

6(Number of hours worked) = 9 + (1.5 * (Number of hours worked))Solving this equation gives us: Number of hours worked = 9/4 = 2.25 hoursSo after 2.25 hours, they each need to work in order to have earned the same amount of money.

Step-by-step explanation:

Jayden's equation: 6x

Brooklynn's equation: 9x + 1.5y

Equation to find how many hours each need to work: 6x = 9x + 1.5y

After 12 hours, they each need to work in order to have earned the same amount of money.

Step-by-step explanation:

To answer this problem, we may use the information provided about the quadrilateral's side ratio and the difference between the smallest and longest sides.

To begin, we may utilize the difference in length between the shortest and longest sides (7.5 cm) to establish a baseline for one of the sides. We may infer that the shortest side is 7.5 cm and the longest side is (7.5 cm + 7.5 cm) = 15 cm since the difference between the shortest and longest sides is 7.5 cm.

We can calculate the length of the other three sides using the side ratio:

We sum together all the sides to find the quadrilateral's perimeter:

Perimeter = 67.5 cm = 7.5 cm + 11.25 cm + 18.75 cm + 30 cm

As a result, the quadrilateral's perimeter is 67.5 cm.

The formula that can be used to represent this function is N*L^2 = k

The number of animal species, N, is inversely proportional to the square of the body length, L. Therefore, the formula representing the function would be:

N = k/L^2

Where k is the proportionality constant. It represents the relationship between N and L^2, and it is a constant value.

The above formula can also be written as

N*L^2 = k

It means that the product of N and L^2 is constant.

It can be derived by assuming that there is some proportionality constant k such that N=k/L^2 and then testing this relationship against data on animal species and body lengths.

A graph that does not show a straight line shows a non-proportional relationship between x and y.

A graph that does not show a straight line, but instead shows a curve, would represent a non-proportional relationship between x and y. A non-linear or curved graph indicates that the relationship between the two variables is not a constant ratio or proportionate relationship. The slope of a line that represents a non-proportional relationship will change depending on the x-value.

A non-proportional relationship exists between two variables when the ratio of their values does not stay constant. In other words, the relationship is not directly proportional. In mathematical terms, this means that the slope of a graph of the relationship is not constant, and the graph will not be a straight line. Instead, it will be a curved line. A non-proportional relationship is also known as a non-linear relationship.

For example, the relationship between the time it takes to run a certain distance and the distance run is non-proportional. If it takes you 10 minutes to run 1 mile, it will not necessarily take you 20 minutes to run 2 miles. The time it takes to run a certain distance increases at a faster rate than the distance run.

In a non-proportional relationship, there is no constant of proportionality. For example, y = 2x doesn't have a constant of proportionality because the ratio of y to x changes as x increases, and the slope of the line is not constant.

Therefore, A graph that does not show a straight line shows a non-proportional relationship between x and y.

Properties of Special right angled triangle,

a) If the leg of a 45°-45°-90° right triangle is x units, then the length of hypotenuse is x√2 units.

b) If a 30°-60°-90° right triangle the hypotenuse is twice the shorter leg, then longer leg is √3 times the shorter leg.

We have to discuss properties of special Right Triangles :

a) Properties of 45°-45°-90° Triangles : The sides of a 45°-45°-90° right triangle have a special relationship.

Example 1: If the leg of a 45°-45°-90° right triangle is x units, show that the hypotenuse is x√2 units.

Using the Pythagorean Theorem with

a = b = x, then c² = a² + b²

=> c² = x² + x²

=> c² = 2x²

=> c = √2x²

=> c = x√2

Thus, hypotenuse is x√2 units.

b) The sides of a 30°-60°-90° right triangle also have a special relationship.

Example 1: In a 30°-60°-90° right triangle the hypotenuse is twice the shorter leg. Show that the longer leg is √3 times the shorter leg.

∆MNQ is a 30°-60°-90° right triangle, and the length of the hypotenuse MN is two times the length of the shorter side NQ. Use the Pythagorean Theorem, c² = a²+ b²

let length of shorter side of ∆MNQ, NQ= x units, so, length of hypotenuse,MN = 2x

=> MN² = NQ² + MQ²

=> MQ² = MN² - NQ²

=> MQ² = (2x)² - x²

=> MQ² = 4x² - x² = 3x²

=> MQ = √3x²

=> MQ = √3 x = √3 NQ

So, longer side of right angled triangle is √3 times the short side.

There are 2 pounds of apples Hannah buy for the cost for her purchase to be the same from both stores.

Given that;

At Giant Eagle, a box of cereal costs $2.89 and apples cost $1.29 per pound.

And, At Shop & Save, the apples are $1.05 per pound and a box of

cereal is $3.37.

Now,

Let number of pounds of apples can Hannah buy for the cost for her purchase to be the same from both stores = x

So, We can formulate;

For, At Giant Eagle, a box of cereal costs $2.89 and apples cost $1.29 per pound.

The total cost is,

⇒ $2.89 + $1.29x

And, For Shop & Save, the apples are $1.05 per pound and a box of

cereal is $3.37.

Total cost is,

⇒ $3.37 + $1.05x

Now, We can equate both the equation to find the number of pounds of apple to buy.

⇒ $3.37 + $1.05x = $2.89 + $1.29x

⇒ 3.37 + 1.05x = 2.89 + 1.29x

⇒ 3.37 - 2.89 = 1.29x - 1.05x

⇒ 0.48 = 0.24x

⇒ x = 0.48 / 0.24

⇒ x = 2

The derivative of x² log x is 2x log x + x/ ln(10).

The derivative of a function f(x) is usually represented by d/dx (f(x)) (or) df/dx (or) Df(x) (or) f'(x). Let us see what a derivative technically means. Consider a curve of function f(x) and let two points on it be (x, f(x)) and ((x + h), f(x + h)). Then the slope of the secant line through these points is given by [f(x + h) - f(x)]/(x + h - x) = [f(x + h) - f(x) / h. See the figure below and observe that when the distance between two points is closely equal to 0 (i.e., as h approaches 0), the second point overlaps the original point and the secant line becomes the tangent line. In calculus, the slope of the tangent line is referred to as the derivative of the function.

The derivative of a function at a point is the slope of the tangent drawn to that curve at that point.

It also represents the instantaneous rate of change at a point on the function.

The velocity of a particle is found by finding the derivative of the displacement function.

The derivatives are used to optimize (maximize/minimize) a function.

They are also used to find the intervals where the function is increasing/decreasing as well as the intervals where the function is concave up/down.

Given equation: y = x² log x

Differentiating this equation with respect to x, we get

dy/dx = 2x log x + x/ ln(10)

Thus, the derivative of x² log x is 2x log x + x/ ln(10).
