Using Pythagoras theorem, the hypothenuse is equal 4 units

Pythagoras theorem states that in a right triangle, the square of the length of the longest side (the hypotenuse) is equal to the sum of the squares of the lengths of the other two sides. Mathematically, it can be expressed as a²+ b² = c², where a and b are the lengths of the two shorter sides, and c is the length of the hypotenuse.

The length of the third side is the hypothenuse and we can use Pythagoras theorem to find that.

a²+ b² = c²

3² + (√7)² = c²

9 + 7 = c²

c² = 16

Taking the square root of both sides;

c = √16

c = 4

Households with negative or zero net worth may have high credit card debt due to financial distress, using credit to cover everyday expenses, or difficulty managing finances.

Financial distress: Households with negative net worth may be in financial distress and may be relying on credit cards to cover their basic expenses. This can lead to high levels of credit card debt as they continue to use their credit cards to pay for necessities such as food, housing, and utilities.

Financing everyday expenses: Households with zero net worth may also have high levels of credit card debt if they are using their credit cards to finance their everyday expenses. This can happen if they do not have sufficient income to cover their expenses, or if they have high levels of fixed expenses such as mortgage or rent payments.

Difficulty managing finances: Households with negative or zero net worth may also have a harder time managing their finances and may be more prone to making financial mistakes such as missing credit card payments or making late payments. This can lead to higher levels of credit card debt as they incur late fees and interest charges.

Households with net worth in the negative or zero have the highest average credit card debt due to the lack of other financing options available to them.

The reason why households with net worth in the negative or zero have the highest average credit card debt is likely due to the fact that they have less access to other financing options and thus rely more heavily on credit cards. When a household has no net worth, they are unable to turn to other sources of borrowing such as home equity loans or personal loans, as they have no equity to borrow against. Therefore, they are more likely to use credit cards to cover unexpected expenses or emergency needs. In addition, households with zero or negative net worth may have lower income and less access to savings, causing them to rely heavily on credit cards for daily expenses.

To illustrate this concept, let’s assume that there are two households with different levels of net worth. Household A has a net worth of $10,000 and Household B has a net worth of -$2,000. Both households have monthly expenses of $1,000 and an income of $2,000. Household A has more financial flexibility because they can turn to other sources of borrowing to cover their expenses, such as home equity loans or personal loans. Household B, however, is unable to borrow against their negative net worth and must rely solely on credit cards to cover their monthly expenses. This makes them more likely to accumulate higher levels of credit card debt due to their limited access to other financing options.

Therefore, it is evident that households with net worth in the negative or zero have the highest average credit card debt due to the lack of other financing options available to them.

Point (80, 185) represents the location of the beetle 5 seconds after starting.

An equation of this type is known as a parametric equation; it uses an independent variable known as a parameter (commonly represented by t) and dependent variables that are defined as continuous functions of the parameter and independent of other variables. When necessary, more than one parameter can be used. For instance, the equation y = x2 can be expressed as a pair of equations in parametric form, x = t and y = t2, rather than the Cartesian form of y = x2. Parameterization, which transforms a function into a parametric form, greatly improves the efficiency of differentiating and integrating curves.

Step-by-step explanation: 15 • 3 + 15 + 6 = 66

Statement: 5(x+6)=x+38 is x=2

We are given the equation 5(x+6)=x+38. We can solve this equation by isolating x on one side of the equation. To do this, we will first subtract x from both sides of the equation. This will leave us with 5x+30=38. We can then subtract 30 from both sides of the equation to isolate the x terms. This leaves us with 5x=8. We can then divide both sides of the equation by 5 to isolate x. This gives us x=2.

Therefore, if 5(x+6)=x+38, then x=2.

The Given Statement is  true reason is the value in the left-hand side is equal to the value in the right-hand side. it shows proof that 5(x+6) = x+38 for x =2.

Here we have to understand what is an equation because in question we have given an equation.

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("="). For illustration, 2x - 5 = 13.

2x - 5 and 13 are expressions in this case.

These two expressions are joined together by the sign "=".

Two expressions are combined in an equation using an equal symbol ("="). The "left-hand side" and "right-hand side" of the equation are the two expressions on either side of the equals sign. Typically, we consider an equation's right side to be zero. Since we can balance this by deducting the right-side expression from both sides' expressions, this won't reduce the generality.

Here we have given an equation

5(x+6) = x+38  we have to proof for x = 2.

LHS 5(x+6) = 5(2+6) = 5*8 = 40

RHS x+38 = 2+38 = 40

Using the diameter given, the volume of the sphere is 14137.17cm³

The volume of a sphere is a measurement of how much space it takes up. It is calculated using the following formula and represents the volume of the sphere:

v = 4/3 * π * r³

Where: r is the radius of the sphere, which is the distance from the sphere's center to its surface, and π is a mathematical constant roughly equal to 3.14.

The formula is based on the observation that a sphere's volume is two thirds that of a cylinder with the same radius and height.

The volume of a sphere is directly proportional to the cube of the radius, which is a crucial point to remember.

In the problem, the diameter given is 30cm, we can calculate the radius from this.

radius = diameter / 2

radius = 30 / 2

radius = 15cm

We can plug in the values to calculate the volume of this sphere;

v = 4/3πr³

When working on complicated problems, it's best to break things down as much as possible.

Toby knows how to work with 2 terms, so let's start with that.

Ignore the 8^2 for now.

Focus on the first 2 exponential terms 8^7 and 8^3.

Multiply them to get: 8^7*8^3 = 8^(7+3) = 8^10

Which Toby should know how to do. The general rule is

a^b*a^c = a^(b+c)

Add the exponents but only when the bases are the same.

-----------------------------

This means

8^7* 8^3*8^2

is the same as

8^10*8^2

Then apply that rule again to get

8^10*8^2 = 8^(10+2) = 8^12

-----------------------------

So overall, 8^7*8^3*8^2 = 8^12

In other words, we add the exponents to get 7+3+2 = 12 as the final exponent. The base stays at 8 the entire time.

The reasons for each statement about the given triangle are as follows:

Congruent triangles are two triangles that are the same size and shape. Two congruent triangles remain congruent even if we flip, turn, or rotate one of them. Two triangles must have the same angles and, as a result, must be congruent if their sides are the same.

Given, A triangle PWZ in that base ∠1 and ∠2 are same and the distance between W and Z from X and Y are the same where XY is the base of another triangle inside the ΔPWZ.

For ΔPWZ

We know PWZ is an isosceles triangle since its two angles are the same.

thus another ΔPXY is on the same base of ΔPWZ and also at the same distance from its point Hence, these triangles are congruent triangles.

Looking at that perspective, we can say that ∠1 and ∠2 are pairs of alternate angles and are congruent.

∠1 ≅ ∠2

The same with ∠3 and ∠4.

∠3 ≅ ∠4

The general form of an exponential decay function is f(a) = P . (1 - r)ᵃ, hence a function is an exponential decay if the factor (1 - r) is less than 1.

The general exponential decay function can be written as:

f(a) = P . (1 - r)ᵃ

Where:

P = initial quantity

f(a) = remaining quantity at time a

a = time period

r  = decay rate

(1 - r) = decay factor

On the other hand, the general exponential growth function can be written as:

f(a) = P . (1 + r)ᵃ

Hence, the difference between decay function and growth function is: the factor in decay faction is less than 1, while in growth function, the factor is greater than 1.

Example:

f(a) = 6 . (0.25)ᵃ

This is an exponential decay function because the factor is less than 1, that is 0.25

f(a) = 10 . (3)ᵃ

[tex]2x[/tex] = 24 - [tex]y^{2}[/tex]

[tex]x[/tex] = 12 - [tex]\frac{y^{2} }{2}[/tex]

Finding limits:

y = 12 - [tex]\frac{y^{2} }{2}[/tex]

12 - [tex]\frac{y^{2} }{2}[/tex] - y = 0

Multiply by 2 to facilitate calculations:

24 - [tex]y^{2}[/tex] - 2y = 0

Resolving quadratic equation:

- [tex]y^{2}[/tex] -2y + 24 = 0

- ([tex]y^{2}[/tex] + 2y - 24 ) = 0

Divide both sides the same factor,

[tex]y^{2}[/tex] + 2y - 24  = 0

Use Quadratic formula,

y = (-b ± [tex]\sqrt (b^{2} -4ac)[/tex] ) / 2a

y = (-2 ± [tex]\sqrt{2^{2}-4*1*(-24) }[/tex] ) / 2*1

y = (-2 ± [tex]\sqrt{4+96}[/tex] ) / 2

y = (-2 ± [tex]\sqrt{100}[/tex] ) / 2

y = (-2 ± 10 ) / 2

y = (-2 + 10 ) /2  ,     y = (-2 - 10 ) /2  

y = 8/2  ,                  y = -12/2

y = 4   ,                     y = -6

y = 4 and y = -6

Then, integral to calculate area will be with limits -6<y<4:
