For the given scenario:

Using transformations, the functions that could represent the one graphed are given as follows:

A transformation is when a function undergoes a change in it's definition. Depending on the type of the transformation, the function can keep the same orientation, same side lengths, and so on.

In the context of this problem, the function kept the same orientation, it just changed it's position, hence the type of transformation that the function underwent was a translation.

The possible translations are given as follows:

The domain of the graphed function is given by:

x ≥ 0.

Which is the same domain as the parent square root function, given as follows:

y = sqrt(x).

From the graph, the function was translated down a units, changing it's range, hence the function has the following format:

y = sqrt(x) - a.

Hence the first two options can be correct, either with a = 1 or with a = 3. The last two options change the range but not the domain, hence they are incorrect.

The image at the end of the answer gives the complete problem.

The factorised form of the algebraic expression 16cd − 56c²d as given in the task content is; 8cd (2 - 7c).

It follows from the task content that the factorised form of the expression; 16cd − 56c²d as given is to be determined.

Since the given expression is;

16cd − 56c²d

First, each of the terms can be factored as follows;

16cd = 2 × 2 × 2 × 2 × c × d

56c²d = 2 × 2 × 2 × 2 × 7 × c × c × d

Therefore, since the factors which are common to both terms as follows; 2 × 2 × 2 × c × d = 8cd.

Therefore the factorised form of the expression is;

The domain of f⁻¹(x) is (9,∞).

The function we have is

f(x) = 4x² + 9 for x ≤ 0

Now, let us find the inverse of the function f(x),

To find the inverse of f(x),

Replacing f(x) with f(y)

f(y) = 4y² + 9

Now the equation is,

x = 4y² + 9

y² = (x-9)/4

y = √(x-9)/2

The inverse of f(x) is,

f⁻¹(x) = √(x-9)/2

The domain of √(x-9)/2 can be found as,

Answer:

i think it is 7 but not sure

Step-by-step explanation:

GCF of 28 and 35 is the largest possible number that divides 28 and 35 exactly without any remainder. The factors of 28 and 35 are 1, 2, 4, 7, 14, 28 and 1, 5, 7, 35 respectively. There are 3 commonly used methods to find the GCF of 28 and 35 - prime factorization, Euclidean algorithm, and long division.

Answer:

The rate at which the surface area is changing with respect to time when r = 40 cm is 22400π cm²/min

Not sure if you want it in absolute values since the question says use symbolic notation but if so, multiplying by π gives 70371.675 cm²/min

Step-by-step explanation:

[tex]\text {Volume of a sphere of radius r is given by }\\\\ \text {$V = \dfrac{3}{4}\pi r^3$}[/tex]

The surface area of a sphere of radius r is given by:

[tex]\\S = 4\pi r^2\\[/tex]

The rate of change of surface area is given by
[tex]\dfrac{dS}{dt} = \dfrac{d}{dt}\left(4\pi r^2\right)}\\\\\dfrac{dS}{dt} = 4 \pi \dfrac{d}{dt}\left( r^2\right)}\\\\\\\dfrac{d}{dt}(r^2) = 2r\dfrac{dr}{dt}\\\\\\[/tex]

[tex]\dfrac{dS}{dt} = 8\pi r \dfrac{dr}{dt}[/tex]

We are given that [tex]\text{$\dfrac{dr}{dt}$}[/tex] = 70 cm/min and asked to find rate of change of S when r = 40 cm

Substituting these values into the equation for [tex]\dfrac{dS}{dt}[/tex]
[tex]\dfrac{dS}{dt} = 8 \pi \cdot 40 \cdot 70\\\\\\\\\dfrac{dS}{dt} = 22400 \pi \;cm^2/min[/tex]

The most appropriate choice for perimeter of rectangle will be given by-

Mr Smith must buy 61 m of fencing.

What is perimeter of rectangle?

It is equal to the total distance of the boundary of the rectangle.

If length of rectangle is l m and breadth of rectangle is b m, perimeter of rectangle is 2 x (l + b) [tex]m^2[/tex]

Here,

Length of yard = 61 ft

Breadth of yard = 39 ft

Perimeter of yard = 2 x (61 + 39)

                             = 2 x 100

                             = 200 ft

1 ft = 0.305 m

200 ft = 0.305 x 200 m

          = 61 m

Mr Smith must buy 61 m of fencing.

The distance expression of the number of units between points A and B is √[(-2 - 3)^2 + (5 - 5)^2]

From the question, we have the following parameters:

This means that

A = (-2, 5)

B = (3, 5)

The distance between the points is calculated as

Distance = √[(x2 - x1)^2 + (y2 - y1)^2]

Where

A = (x1, y1) = (-2, 5)

B = (x2, y2) = (3, 5)

Substitute the known values in the above equation

So, we have

Distance = √[(-2 - 3)^2 + (5 - 5)^2]

The question does not imply that the we simplify the above expression

So, we leave the expression unsimplified

Hence, the expression of the distance between A and B is √[(-2 - 3)^2 + (5 - 5)^2]

The width of the rectangle DOGS is 119cm

To solve this, since is a ratio problem, we know that the two ratios must add to the total. This is, for a ratio of 5:7, 5 + 7 = 12 is the total "divisions" for the ratio.

This means that if 12 of 12 parts add to the perimeter (408cm):

12/12 represents the perimeter 408cm.

The, we can divide the perimeter by 12 and get:

Since the width is 7/12 of the perimeter:

But, we are taking the perimeter of a rectangle, which is twice the width plus twice the length, thus we need to divide this number by 2:

And we get the final answer of 119cm

Answer:

Step-by-step explanation:

Volume of solid of revolution formed by rotating about the x axis the region between the graph of f(x)= x /2 and the x axis between x=2 and x=5 is 117π /12unit³.

As given,

Volume of solid of revolution formed by rotating about the x-axis region between the graph of f(x)= x /2:

Volume = π∫[f(x)]²dx  

⇒Volume =π∫(x/2)²dx

⇒Volume =(π/4)∫x²dx

⇒Volume =(π/4) (x³/3)

                 =(π/12)(x³)

x axis between x=2 and x=5

Volume =(π/12)(125-8)

             =117π/12 unit³
