A line passes through point (-4, 8) and has a slope of 5 over 4

The area of the enclosed region is 83.4 square units.

To calculate the integral, first determine the limits, which will be the points where both curves meet.

The area will be integrated with respect to y.

In respect to y:

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

[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:

A = [tex]\int\limits^[/tex] 12 - [tex]\frac{y^{2} }{2}[/tex] - y dy

A = 12y - [tex]\frac{y^{3} }{6}[/tex] - [tex]\frac{y^{2} }{2}[/tex]

A = 12*4 - [tex]\frac{4^{3} }{6}[/tex] - [tex]\frac{4^{2} }{2}[/tex] - [12(-6) - [tex]\frac{-6^{3} }{6}[/tex] - [tex]\frac{-6^{2} }{2}[/tex] ]

A = 48 - 10.6 - 8 - [ -72 + 36 - 18 ]

A = 48 - 10.6 - 8 + 72 - 36 + 18

A = 83.4

Therefore,

The area of the enclosed region is 83.4 square units.

The tangent to the graph f,  f(x) = [tex]5x^4[/tex]/4 + 15/4.

When infinitesimal data are combined, notions such as displacement, area, and volume can be created. An integral assigns numbers to functions in a way that describes these concepts. Integration is the action of locating integrals.

Given:

f '(x) = 5x³

and, line: 5x + y= 0

We integrate to get f(x) = ∫5x³ dx = [tex]5x^4[/tex]/4 + C.

As, tangent line is y = - 5x,

then f'(x) = 5x³ = - 5, x³ = -1 and x = -1 is x-coordinate of tangent point.

So, the y-coordinate of tangent point is

f(-1) = 5[tex](-1)^4[/tex]/4  + C

      = 5/4 + C.

and, the equation of tangent line is

y - 5/4 - C = - 5(x + 1)

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;

Answer: the answer is £12.

Step-by-step explanation:

To solve this problem, we can set up an equation to represent the information given in the problem. Let's call the amount of money Hasim had at the beginning of the day x.

We know that Hasim gave his brother 1/3 of his money, so we can represent that with the equation:

x / 3 = y

Where y is the amount of money Hasim gave to his brother.

We also know that Hasim spent £12 on a present for his sister, so we can subtract that amount from x to find the amount of money he had left:

x - 12 = z

Where z is the amount of money Hasim had left after buying the present.

Finally, we are told that the amount of money Hasim had left is half of what he had at the beginning of the day, so we can represent that with the equation:

x / 2 = z

Now we have three equations that all involve the variable x. We can solve for x by substituting the first equation into the second and third equations:

x / 3 = x - 12

x / 2 = x / 3

Solving these equations, we find that x = 36.

This means that Hasim had £36 at the beginning of the day, and gave his brother £36 / 3 = £<<36/3=12>>12.

Answer:

x = -4

y = -3

Step-by-step explanation:

-4x + 4y = 4          Eq.  1

y = 3x + 9             Eq. 2

Replacing Eq. 2 in Eq. 1:

-4x + 4(3x+9) = 4

-4x + (4*3x + 4*9) = 4

-4x + (12x+ 36) = 4

8x + 36 = 4

8x = 4 - 36

8x = -32

x = -32/8

x = -4

From Eq. 2

y = 3*-4 + 9

y = -12 + 9

y = -3

Check:

From Eq. 1

-4x + 4y = 4

-4*-4 + 4*-3 = 4

16 - 12 = 4

g(2) is -1/4 for function g(x)= 1-x/x².

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.

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.

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 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

This is not an exponential decay function, but a growth function,  because the factor is greater than 1, that is 3

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.

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.
