Answer:

x=y+1,y=y

Step-by-step explanation:

The main difference between the reciprocal and inverse of a function is their definition and properties. The reciprocal of a function f(x) is defined as 1/f(x), while the inverse of a function f(x) is a function f^(-1)(x) such that \(f(f^(-1)(x))=x and f^(-1)(f(x))=x\) for all x in their respective domains.

The domains of sine, cosine, and tangent functions need to be restricted to define their inverse functions because they are not one-to-one functions. In order to have an inverse, a function must be both one-to-one (each output has only one input) and onto (each output value is mapped by at least one input value).

For example:
- sine: restricted domain to [-π/2, π/2] to define its inverse, arcsin (sin^(-1))
- cosine: restricted domain to [0, π] to define its inverse, arccos (cos^(-1))
- tangent: restricted domain to (-π/2, π/2) to define its inverse, arctan (tan^(-1))

These restrictions ensure that the functions become one-to-one and onto, making it possible to define their inverses uniquely.

Sammy originally took out approximately $5357.14 to fund his education.

The rate of interest, also known as the interest rate, is the percentage amount charged by a lender or financial institution for the use of borrowed money or for the extension of credit. It is the cost of borrowing money, typically expressed as an annual percentage of the amount borrowed or owed.

Let X be the amount Sammy took out originally to fund his education.

After 5 years, the amount he has to pay back is X + (0.08X5) = X + 0.4X = 1.4X.

We know that 1.4X = $7500, so we can solve for X:

1.4X = $7500

X = $7500 / 1.4

X ≈ $5357.14

Therefore, Sammy originally took out approximately $5357.14 to fund his education.

Step-by-step explanation:

To find the equation of a line perpendicular to y = 3x and passing through the point (3,1), you can determine the slope (m) and y-intercept (b) of the new line.

The slope of the perpendicular line is the negative reciprocal of the slope of the original line, and the y-intercept remains the same.

The slope-intercept form of a line is y = mx + b, where m represents the slope and b represents the y-intercept. To find the slope (m) of the perpendicular line, we need to take the negative reciprocal of the slope of the original line.

In this case, the slope of y = 3x is 3. The negative reciprocal of 3 is -1/3. So, the slope of the perpendicular line is -1/3.

To find the y-intercept (b) of the perpendicular line, we can substitute the coordinates (3,1) into the equation y = mx + b and solve for b. Using the slope-intercept form and substituting the values, we have 1 = (-1/3) * 3 + b. Simplifying this equation gives us 1 = -1 + b.

Adding 1 to both sides, we find b = 2.

Therefore, the equation of the line perpendicular to y = 3x and passing through the point (3,1) is y = (-1/3)x + 2.

If the radius of the scoop of ice cream at Double Rainbow is decreasing at a rate of 2.5 millimeters (mm) per minute and the radius is 4 centimeters (cm), then we need to find out the rate at which the volume of the ice cream is changing. The volume of a sphere is given by the formula V = 4/3πr³.

Now, we can differentiate this equation with respect to time t to get dV/dt = 4πr²(dr/dt), where dV/dt represents the rate at which the volume is changing and dr/dt represents the rate at which the radius is changing. We have dr/dt = -2.5 mm/min because the radius is decreasing at the rate of 2.5 mm/min.

We also know that 10 mm = 1 cm. Hence, dr/dt = -0.25 cm/min (since 2.5 mm = 0.25 cm). Now, we can substitute r = 4 cm and dr/dt = -0.25 cm/min in the equation dV/dt = 4πr²(dr/dt) to get the rate at which the volume is changing. We have dV/dt = 4π(4)²(-0.25) = -8π cm³/min. Therefore, the volume of the ice cream is decreasing at a rate of 8π cm³/min when the radius is 4 cm.

According to the figure's surface area, 712 square centimeters,

A prism is indeed a solid form that is enclosed by flat faces on all of its sides. A prism has two different kinds of faces. Bases refer to the identical top and bottom faces. The word "prism" refers to the form of these bases. For instance, a prism is referred to be a triangular prism if its base is triangular.

We must sum up the places of all the faces of a two rectangular prisms in order to determine the contact area of the this L-shaped composite figure.

First, we'll find the area of the faces of the first prism.

It has a length of 20 cm, a width of 4 cm, and a height of 8 cm.

So, the area of the front face is 204 = 80 sq cm.

The area of the back face is also 80 sq cm.

The area of the top face is 48 = 32 sq cm.

The area of the bottom face is also 32 sq cm.

The area of the right face is 8*20 = 160 sq cm.

The area of the left face is also 160 sq cm.

Now, we'll find the area of the faces of the second prism.

It has a length of 20 cm, a width of 10 cm, and a height of 2 cm.

So, the area of the front face is 2010 = 200 sq cm.

The area of the back face is also 200 sq cm.

The area of the top face is 102 = 20 sq cm.

The area of the bottom face is also 20 sq cm.

The area of the right face is 2*20 = 40 sq cm.

The area of the left face is also 40 sq cm.

Now, we need to subtract the area of the shared face from both prisms. The shared face is 20*2 = 40 sq cm. So, we need to subtract 40 sq cm from both prisms.

So, the total surface area of the figure is (80+80+32+32+160+160) + (200+200+20+20+40+40) - (40+40) = 712 sq cm.

Therefore, the surface area of the figure is 712 square centimeters.

To calculate the quantity demanded when the price is $44, we first need to identify the price points on either side of $44. In this case, $31 and $57 are the two price points. We then look at the corresponding quantities at those two points, which are q* (30 units) and q1 (50 units).

From binomial probability, (nCx)px(1p) is where the application of binomial probability originates from (n-x)

1 - p = 0.96

a) P(x=1) is the probability that precisely 1 received a special accommodation.

= 15C1 x (0.04)^1 x (0.96) ^14 = 0.3388

b) P(x >=1) = 1 - P(x = 0) is the likelihood that at least 1 person received a special accommodation.

= 1 - [ 15C0 x (0.04)^0 x (0.96)^15 = 0.4579

c) the likelihood that two people at least obtained special accommodations

= [P(x = 0) + P(x = 1)] - [P(x>=2) = P(x>=2)

The equity of the entity, according to the basic accounting equation, is R6 000. The basic accounting equation is Assets = Liabilities + Equity. To find the equity of the entity, we need to subtract the total liabilities from the total assets.

Bank balance: R5 000

Machinery balance: R3 000

Trade payables: R2 000

Total assets = Bank + Machinery

            = R5 000 + R3 000

            = R8 000

Total liabilities = Trade payables

                 = R2 000

Equity = Total assets - Total liabilities

      = R8 000 - R2 000

To solve the problem we will put the values given to us in the formula of volume of a prism.

A prism is a 3d shape whose two sides are the base sides which are polygon, with the other faces as parallelograms.

The height of the prism is \(\dfrac{(x^3-3x^2+5x-3)}{(x^2-2)}\).

Given to us

As given  to us,

\(\rm{ Volume\ of\ prism = Area\ of\ base \times Height \)

\(\rm{ Height=\dfrac{Volume\ of\ prism}{Area\ of\ base}\)

Substituting the values we get,

\(\rm{ Height=\dfrac{(x^3-3x^2+5x-3)}{(x^2-2)}\)

To calculate the approximate volume of concrete that Angel will use, we need to determine the volume of the slab.

The slab is in the shape of a cylinder, and its volume can be calculated using the formula:

V = πr²h

where V is the volume, r is the radius, and h is the height of the cylinder.

From the given information, we know that the slab is 6 inches tall. However, we need to convert the dimensions to the same unit before proceeding with the calculations. Let's convert the dimensions to feet:

Height = 6 inches = 6/12 feet = 0.5 feet

Radius = 2 feet

Now we can substitute the values into the formula to find the volume:

V = π(2²)(0.5)

 = π(4)(0.5)

 = 2π cubic feet

Approximating π to 3.14, we can calculate the volume:

V ≈ 2(3.14)

 ≈ 6.28 cubic feet

Therefore, the approximate volume of concrete that Angel will use is 6.28 cubic feet.

Looking at the given answer choices, the closest value to 6.28 is 10 cubic feet. Therefore, the correct answer is:
