Hence, in answering the stated question, we may say that We know, equation however, that r must be positive, therefore we take the positive square root: \(r(A) = -4 + square root(64 + 2A) /\)

A math equation is a method that links two claims and represents equivalence using the equals sign (=). An equation is a mathematical statement that establishes the equivalence of two mathematical expressions in algebra. In the equation 3x + 5 = 14, for example, the equal sign separates the numbers 3x + 5 and 14. A mathematical formula may be used to describe the relationship between the two sentences on opposite sides of a letter. In usually, the logo and the programme are the same. For instance, 2x - 4 equals 2.

Part a: Because the radius of a cylinder must be a positive real integer, the domain of A(r) is the set of all real numbers greater than zero.

As a result, the domain of A(r) is:

{r ∈ ℝ | r > 0}

Part b: To determine the inverse function r(A), solve the equation A = 2r2 + 16r for r expressed in terms of A.

To begin, we may simplify the equation by removing 2r:

A = 2πr(r + 8)

Hence, using the quadratic formula, we can find r:

\(r = (-16 \sqrt((16)2 - 4(2 )(-A)) / 2(2 )\\r = (-16 \sqrt(2562) + 8A) / 4 r = -4 \sqrt(64 + 2A) /\)

We know, however, that r must be positive, therefore we take the positive square root:

\(r(A) = -4 + square root(64 + 2A) /\)

A math equatiοn is a methοd that links twο claims and represents equivalence using the equals sign (=). An equatiοn is a mathematical statement that establishes the equivalence οf twο mathematical expressiοns in algebra.

Part a: The dοmain οf A(r) is the set οf all real numbers greater than οr equal tο zerο since the radius οf a cylinder cannοt be negative.

Dοmain οf A(r): r ≥ 0

Part b: Tο find the inverse functiοn r(A), we start with the equatiοn fοr A(r), set it equal tο A, and sοlve fοr r using the quadratic fοrmula:

\(2 \pi r^2 + 16 \pi r - A = 0\)

\(r = [-16 \pi \± \sqrt{((16 \pi)^2 - 4(2 \pi)(-A))}] / 2(2 \pi)\)

\(r = [-16\pi \± \sqrt{(256\pi^2 + 8 \pi A)}] / 4\pi\)

Simplifying this expressiοn, we get:

\(r = (-4 \± \sqrt{(64 + 2A)}) / 2\)

\(r(A) = -2 \± \sqrt{(32 + 0.5A)\)

Since the radius οf a cylinder cannοt be negative, we take the pοsitive square rοοt:

\(r(A) = -2 + \sqrt{(32 + 0.5A)\)

Part c: Tο find the radius when the surface area is 300 square inches, we plug in A = 300 intο the expressiοn fοr r(A) and simplify:

\(r(300) = -2 + \sqrt{(32 + 0.5(300))\)

r(300) = -2 + sqrt(182)

r(300) ≈ 11.51

Therefοre, the radius is apprοximately 11.51 inches when the surface area is 300 square inches.

Answer:

9 years old

Step-by-step explanation:

Let maggie's age be m,

and let maggie's brother's age be b

b = 2m - 5,

m + b = 22

Substitute "2m - 5" for b in the second equation (substitution)

m + (2m - 5) = 22 -> Remove parenthesis

m + 2m - 5 = 22 -> Combine like terms

3m = 22 + 5 = 27 -> Divide either side by 3

m = 27/3 = 9

Solution: Maggie is 9 years old

The Required sequence of the arithmetic progression will be,

= 21, 18, 15, 12, 9, 6

According to the question,

The term that is given is the third term of the sequence = 15

Let the fourth term of the sequence be = x

Let the sixth term of the sequence be = \(\frac{x}{2}\)

So let's make a structure of the sequence=

_, _, 15, x, _, \(\frac{x}{2}\)

Let us consider d as the difference between two terms,

d = x - 15

x = 15 + d -------- equation 1

According to the arithmetic progression if we add the difference of x and 15 into x it will give us the fifth term

let the fifth term be y

x + d = y ------- equation 2

And similarly adding the difference d to y will give the sixth term that is \(\frac{x}{2}\)

y + d = \(\frac{x}{2}\) ------- equation 3

substituting the value of y from equation 2 to equation 3

x + d + d = \(\frac{x}{2}\)

x + 2d = \(\frac{x}{2}\)

2d = - x + \(\frac{x}{2}\)

d = - \(\frac{x}{4}\)

Now substituting the  value of d into equation 1,

x + 15 + (- \(\frac{x}{4}\) )

x + \(\frac{x}{4}\) = 15

\(\frac{5x}{4}\) = 15

x = \(\frac{15 *4}{5}\)

x= \(\frac{60}{5}\)

x = 12

Now we know that the third term of the series x = 12

Similarly the sixth term = \(\frac{x}{2}\)

= \(\frac{12}{2}\)

= 6

So as we can see that the total difference between each term is = 3

Therefore, the required sequence = 21, 18, 15, 12, 9, 6

The smallest positive debt that can be paid off using sticker trading is $7$ dollars.

To find the smallest positive debt that can be paid off using sticker trading, we need to consider the values of the stickers (in dollars) and find the smallest positive amount that can be reached through a combination of these values.

Given that a Harry Potter sticker is worth $49 and a Twilight sticker is worth $35, we can approach this problem using the concept of the greatest common divisor (GCD) of these two values.

The GCD of $49$ and $35$ is $7$. This means that any multiple of the GCD can be represented using these sticker values.

In other words, any positive multiple of $7$ dollars can be paid off using sticker trading.

Therefore, the smallest positive debt that can be paid off using sticker trading is $7$ dollars.

Step-by-step explanation:

To determine whether the given set of ordered pairs {(49,13),(61,36),(10,27),(76,52),(23,52)} represents a function, check if each x-value is associated with a unique y-value.

Check the x-values in the set: 49, 61, 10, 76, and 23. There are no repeated x-values.  Still need to check if each x-value has a unique corresponding y-value.

Check the y-values: 13, 36, 27, 52, and 52. There is one repeated y-value, 52, for the pairs (76, 52) and (23, 52).

Conclusion: the y-value 52 is associated with 2 different x-values, therefore the given set of ordered pairs does not represent a function.

Using percentages we know that 62% or 62 students out of 100 students prefer biology.

For finding k we'll have to plug in the x-value of the coordinate (3,k) into the equation, and solve for the y:

5(3) - 2y = 7

15 - 2y = 7

2y = 8

y = 4 => k =4

2) I assume the gradient is the slope of the line. If so, just isolate the y in the original equation and see what's the coefficient of the x:

-2y = -5x + 7

y = (5/2)x + 7/2 => the gradient is 5/2

3) the condition of perpendicularity is expressed by the following relation:

a * a' = -1

Where a is the slope of the first line and a' of the second line. We need to find a' that will be:

-1/a = -1/(5/2) = -2/5

The perpendicular line will be:

y = (-2/5)x + b

We need to find  b, and we know that this line passes through A (1,-1):

-1 = (-2/5)*1 + b

b = -1+(2/5) = -3/5

The equation will be:

y = (-2/5)x - 3/5.

The intercepts of the parabola are A ( 6 , 0 ) and B ( -2 , 0 ) and the y intercept of the parabola is ( 0 , -12 )

A Parabola, open curve, a conic section produced by the intersection of a right circular cone and a plane parallel to an element of the cone. A parabola is a plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line

The equation of the parabola is given by

( x - h )² = 4p ( y - k )

y = a ( x - h )² + k

where ( h , k ) is the vertex and ( h , k + p ) is the focus

y is the directrix and y = k – p

The equation of the parabola is also given by the equation

y = ax² + bx + c

where a , b , and c are the three coefficients and the parabola is uniquely identified

Given data ,

Let the equation of the parabola be represented as A

Now , the value of A is

y = x² - 4x - 12   be equation (1)

On simplifying , we get

x² - 6x + 2x - 12 = 0

( x + 2 ) ( x - 6 ) = 0

So , the two values of x are

when ( x + 2 ) = 0

x = -2

And , when ( x - 6 ) = 0

x = 6

So , the x intercepts of the parabola are A ( 6 , 0 ) and B ( -2 , 0 )

The y intercept is when x = 0

So , y = 0 - 0 - 12

(y-(-5))/(x-2) = 4

(y+5)/(x-2) = 4

y+5 = 4x - 8

y = 4x - 13

Step-by-step explanation:

Log(x²+8)=log 10+ log x

Log(x²+8)=log(10×x)

x²+8=10x

x² - 10x + 8=0

x is approximately to - 1 and - 8✅

The solutions to the given equation are x = -1 and x = 8.

Option A is the correct answer.

Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.

We also find the solution in a system of equations using the substitution or elimination method.

Example:

2x + 4 = 8

The solution is x = 2.

We have,

Using logarithmic properties, we can simplify the given equation:

logs(x² + 8) = 1 + log g(x)

logs(x² + 8) - log g(x) = 1

log[(x² + 8)/g(x)] = 1

(x² + 8)/g(x) = 10

x² + 8 = 10g(x)

Now we can solve for x by substituting the given answer options and solving for g(x):

For x = -2 and x = -4:

x = -2:

(-2)² + 8 = 12, which is not equal to 10 g(x) for any value of g(x).

So x = -2 is not a solution.

x = -4:

(-4)² + 8 = 24, which is also not equal to 10g(x) for any value of g(x).

So x = -4 is not a solution.

For x = -1 and x = 8:

x = -1:

(-1)² + 8 = 9, which is equal to 10g(x) when g(x) = 0.9.

So x = -1 is a solution.

x = 8:

(8)² + 8 = 72, which is equal to 10g(x) when g(x) = 7.2.

So x = 8 is a solution.

For x = 1 and x = -8:

x = 1:

(1)² + 8 = 9, which is equal to 10g(x) when g(x) = 0.9.

So x = 1 is a solution.

x = -8:

(-8)² + 8 = 56, which is not equal to 10g(x) for any value of g(x).

So x = -8 is not a solution.

Therefore,

The solutions to the given equation are x = -1 and x = 8.

The time taken for the money to grow to $8670 at compound interest is approximately 9.24 years.

Given the amount of money that is the principal = $6000

Rate = 4% compounded quarterly.

Time = t

Amount = $8670

Now we know that the amount is calculated by the formula:

A = P(1+r/4)ⁿ

8670 = 6000(1+0.01)ⁿ

Hence

log 1.445 = n log 1.01

or, n = 36.99

Number of years = 36.99 / 4 = 9.24 years.
