4x you had  0.5x are the y -intercept.

How can you tell whether an exponential function is growing or deteriorating?

You can obviously plot it but if you can also conside that in your function you have 4x

; this tells you that as

x increases (gets bigger) certainly

4x will increase as well (you can consider

4²= 16 and 4³ = 64

). It is true that you have to multiply by

0.5

but nevertheless the entire function will grow anyway!

Graphically:

graph{0.5*(4^x) [-14.24, 14.24, -7.12, 7.12]}

If you want, try to think at the case where instead of having

4x you had  0.5x .

Applying the distance formula, the perimeter of triangle EFG to the nearest tenth is: 25.7 units

The perimeter of triangle EFG with the following points is the sum of all its three sides = EF + FG + EG.

Find the length of each sides of triangle EFG using the distance formula, d = [tex]\sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}[/tex]:

Given:

E(-8,1)

F(1,1)

G(-3,8)

Using the distance formula:

EF = √[(1−(−8))² + (1−1)²]

EF = √81

EF = 9 units

FG = √[(−3−1)² + (8−1)²]

FG = √65

FG ≈ 8.1 units

EG = √[(−3−(−8))² + (8−1)²]

EG = √74

EG ≈ 8.6 units

The account balance invested at 6. 5% annual interest compounded annually will take 19.1 years to reach $50,000.

Compound interest refers to the amount of interest added on the principal amount plus interest. The formula for compound interest is:

B = P(1 + r/n)^t

where B is the ending balance, P is the principal amount or original balance, r is the interest rate in decimal form, n = number of times interest is compounded annually, and t is the time in number of year

Using this formula, find t, the time it will take the account to reach $50,000 when

B = $15,000

r = 6.5% = 0.065

n = 1

B = P(1 + r/n)^t

$50,000 = $15,000(1 + 0.065/1)^t

(1 + 0.065)^t = $50,000/$15,000

In order for the parallelogram to be a rhombus, Then the value of x is equal to 3°.

Rhombus : A rhombus is a diamond-shaped quadrilateral that has all four sides equal. We can see rhombus-shaped figures in our day-to-day lives. Some of the real-life examples of a rhombus are shown in the below-given figure: a diamond, a kite, an earring, etc.

Since Diagonals bisect at 90°

(9x +31)°​ = 180° - 90° - 32°

To solve the product or quotient,

9x = 180° - 90° - 32° - 31°

We can add or subtract the values,

9x = 58° - 31°

We can divide the products,

x = (58° - 31°)/9

x = 27°/9

x = 3°

Therefore,

The value of x must be 3° in order for the parallelogram to be a rhombus.

Therefore √17 will lie between 4 and 4.5 on the number line .

In basic mathematics, real numbers are shown as a graphic of a graduated straight line called a number line. Every point on a number line is considered to correspond to a real number, and every real number is assumed to correspond to a point.

According to one standard, positive numbers always fall on the right side of zero, whereas negative numbers always fall on the left. The line also contains arrowheads at both ends, signifying that it continues in both the positive and negative directions indefinitely.

Let us find the decimal values of the given numbers.

13 lies between 9 and 16 , therefore √13 lies between 3 and 4 on the number line .

17 lies between 16 and 25 , therefore √17 lies between 4 and 5 on the number line .

A finite collection of symbols that is well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression.

Rationalizing the denominator is the process of shifting a root, such as a cube root or a square root, from the fraction's denominator to its numerator (numerator).

Any number of equal parts is represented by a fraction, which also represents a portion of a whole.

The numerator is the part of a fraction that comes before the vinculum.

The denominator of a fraction is the phrase that comes before the vinculum.

Consider the expression,

[tex]\frac{\sqrt{3} x^{5}}{8x^{2}}[/tex]

Now, let [tex]y=\frac{\sqrt{3} x^{5}}{8x^{2}}[/tex]

The amount in a continuously compounded account is $448.30.

Given that the given conditions are the annual interest rate is $400, time is 7.6% and time is 1.5 years.

Continuous compounding means that the account balance is continuously profitable and transfers that interest back to the balance so that it is also profitable.

To find the amount in a continuously compounded account we will use the formula [tex]A=Pe^{rt}[/tex].

[tex]A=400\times e^{(0.076)(1.5)}[/tex]

Now, we will simplify the above expression, we get

[tex]A=400\times e^{0.114}[/tex]

Now, we will evaluate the value of e that is [tex]e^{0.114}[/tex] is 1.120752, we get

A=400×1.120752

A=448.30

Answer:Isolate the g

w = 7 - √g

Do the opposite of PEMDAS, first subtract 7 from both sides

w (-7) = -√g + 7 (-7)

w - 7 = -√g

multiply -1 (as -√g is the same as -1√g) to both sides

-1(w - 7) = √g

-1w + 7 = √g

to get rid of the square root, you must square both sides

Note: -1w is the same as -w

Note: you are squaring all the terms on the other side, not just one.

(-w + 7)² = (√g)²

g = (-w + 7)²

g = (-w + 7)(-w + 7) (note, this can be the answer your teacher wants, or                                            g = (-w + 7)²    )

Use the FOIL method (First, Outside, Inside, Last)

(-w)(-w) = w²

(-w)(7) = -7w

(7)(-w) = -7w

(7)(7) = 49

g = w² - 7w - 7w + 49

simplify (combine all like terms)

g =w² - 7w - 7w + 49

g = w² - 14w + 49

g = w² - 14w + 49 is your answer

This is a translation of one unit up of f(x), and we will get:

Here we need to learn to rewrite functions:

Here we know that:

f(x) = 3x + 2

And

g(x) = x^2 - x

(we will not use g(x) in this problem)

So, f(x) +1 can be rewritten by just replacing f(x) by the equation above, so we can redefine:

h(x) = f(x) + 1

Now we replace the function f of x to get:

h(x) = 3x + 2 + 1 = 3x + 3

The option B , that is , an antique vase valued at $125,000 can be categorized as collateral asset.

What is a collateral asset ?

An asset that a borrower pledges to a lender as a guarantee that the loan will be repaid is known as collateral asset.

We know that the assets that a lender accepts as security for a loan are referred to as collateral. That meant lenders are protected by the collateral in this way. To put it another way, if the borrower stops making loan payments, the lender may be able to sell the collateral to collect some or all of its losses.

So , let's check which of the given option falls under category of collateral.

A.

This is not collateral asset because for a credit card there is no security money given to bank. We only need to pay a maintenance charge and nothing else.

B.

This is a collateral asset.

For an antique vase whose value is $125000 , if the person has purchased this by taking a loan then he would have paid some security money as deposits. If any case he is not able to pay the loan by time the property or the asset becomes collateral which meant the lender may sell the asset to some or all of his losses.

C.

This is not collateral asset because if the loan is repaid in full there will be no extra charges liable on the asset and it can't be categorized as collateral.

Therefore , the option B , that is , an antique vase valued at $125,000 can be categorized as collateral asset.

Step-by-step explanation:

In mathematics, an inverse function is one that "reverses" another function. The inverse function of F(x) = x² - 1 is ±√(x + 1).

The inverse function of a function f in mathematics exists a function that reverses the operation of f. If the inverse of f exists, it is shown by the f⁻¹. The inverse of f exists if and only if f is bijective.

An inverse in mathematics is a function that "undoes" another function. In other words, if f(x) produces y, then y entered into the inverse of f produces x. An invertible function is one that has an inverse, and the inverse is represented by the symbol f ⁻¹.

Let the function be f(x) = x² - 1

y = x² − 1

x = y² − 1

simplifying the above equation, we get

y² = x + 1

y = ± √(x + 1)

Because there are two possible values of y for each value of x, there is no inverse function.

The inverse function of F(x) = x² - 1 is ±√(x + 1).
