Because the base is 1/4, which is smaller than 1, we conclude that this is an exponential decay.

A general exponential function is of the form:

y = A*(b)^x

Where A is the initial value, b is the base, and x is the variable.

If 0 < b < 1, then we have an exponential decay.

if b > 1, then we have an exponential growth.

In this case, the function is:

y = 0.5*(1/4)^x

So b =1/4 <  1.

Then we have an exponential decay.

The Bank discount and proceeds of the given information is:

$2365.27 and $47634.73 respectively.

Given the face value is $50,000

Discount rate = 13%

No.of term days = April 5 to August 14

= 131 days.

Bank discount = ?

Proceeds = ?

First calculate the bank discount using the formula:

Bank discount = face value × discount rate × time

Bank discount = $50,000 × 0.13 × 131/360

= 50,000×0.13×0.36388

= $2365.27

now calculate the proceeds using the formula :

Proceeds = face value - bank discount

= 50,000 - 2365.27

= $47634.73

Hence the bank discount and proceeds are $2365.27 and $47634.73 respectively.

real number can be a complex number but a complex number can not be a real number, verified.

the lengths of the complex number and its conjugate are equal but the converse is not necessarily true., verified.

Not all complex numbers are real numbers, despite the fact that every complex number is a real number.

In fact, determining whether the complex number z = a + bi is real is one of the complex conjugate's most useful applications. If and only if z = a + 0i, a complex number is real. In other words, a complex number is real if it contains an imaginary part.

Mathematical proof:

Let z = a+bi, where a and b = real numbers.

Let z* =complex conjugate of z.

Then the magnitude (absolute value) of z is:

|z| = √(a²+b²).

And the value of z* is:

|z*| = √[a²+(-b)²] = √(a²+b²).

So |z| = |z*|.

This Completes the Proof.

Answer: $30 for 75 copies.

Step-by-step explanation:

    We will set up a proportion to help us solve. Let x be equal to the amount for 75 copies.

         [tex]\displaystyle \frac{10 \ copies}{\$4} = \frac{75 \ copies}{\$x}[/tex]

   Cross-multiply:

    Divide:

x = $30

The equation that could model the given situation is y = -x + 30.25. The correct option is B. y = -x + 30.25

From the question, we are to determine the equation that could model the given situation

The perimeter, P, of a rectangle is given by the formula,

P = 2(l + w)

Where P is the perimeter

l is the length

and w is the width

From the given information,

The perimeter of a rectangular room is 60.5 feet.

∴ P = 60.5 feet

Also,

x is the width of the room and y is the length of the room

That is,

l = y

and

w = x

Thus,

The equation becomes

60.5 = 2(y + x)

2(y + x) = 60.5

Divide through by 2

y + x = 30.25

y = -x + 30.25

Hence,

y = -x + 30.25 is the equation that might be used to model the circumstance.

It takes 53 years until we run out of gas.

Given,

Reserves of natural gas = 6500 TCF

Consumption per year = 123 TCF

Therefore,

years left ( x )= Reserves of natural gas / Consumption per year  

                     = 6500/123

Coplanar lines are referred to as parallel lines because they may be extended indefinitely without ever intersecting. || is the sign meaning "parallel to." If two lines are drawn, they don't have to be parallel, and a third line runs across them as seen in the diagram below. We may obtain eight distinct angles by drawing two parallel lines, and then drawing a transverse line through them.

Four pairs of matching angles will be created from all eight angles. One of the pairings is represented by angles F and B in the preceding diagram. If the two lines are parallel, corresponding angles are congruent.

Answer:

  5 and -3

Step-by-step explanation:

You want two integers that have a sum of 2 and a product of -15.

Solving a problem like this can often be done fairly quickly by listing the factor pairs that make up the product. Only the pairs need be listed that have a sum with the same sign as the sum you're looking for.

Divisors of 15 are 1, 3, 5, and 15. You want a negative product with the largest factor being positive:

  -15 = 15(-1) = 5(-3)

The sums of these factor pairs are 14 and 2. The latter pair is the one of interest.

The two integers are 5 and -3.

__

Additional comment

The desired relations can be expressed as a quadratic equation. It generally works well to solve it by completing the square.

If one of the numbers is x, the other is 2-x. Their product is -15:

  x(2 -x) = -15

  2x -x^2 = -15 . . . . . eliminate parentheses

  x^2 -2x = 15 . . . . . . make the leading coefficient positive

Complete the square by adding the square of half the x-coefficient

  x^2 -2x +1 = 15 +1

  (x -1)^2 = 16

  x -1 = √16 = 4 . . . . . . take the square root

  x = 5 . . . . . . . . . . . add 1

Using the properties of permutation and combination we can calculate that there are possible 3 ,4 ,5 ,6 or 8 people in the group.

A permutation of a set is, broadly speaking, a rearranging of its elements if the set is already ordered, or arranging its members into a sequence or linear order.

There are 2 to 10 people in the group.

Lets us consider there are 3 people. Ticket price = 240 / 3= $80

Lets us consider there are 4 people. Ticket price = 240 / 4= $60

Lets us consider there are 5 people. Ticket price = 240 / 5= $48

Lets us consider there are 6 people. Ticket price = 240 / 6= $40

Lets us consider there are 8 people. Ticket price = 240 / 3= $30

Hence from the properties of permutation and combination we can see that there could be 3 ,4,5,6 or 8 people.

m = 1/3 is the given slope

We'll use the slope formula to solve for h.

[tex](x_1,y_1) = (6,-2) \text{ and } (x_2,y_2) = (h,-3)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\\frac{1}{3} = \frac{-3 - (-2)}{h - 6}\\\\\frac{1}{3} = \frac{-3 + 2}{h - 6}\\\\\frac{1}{3} = \frac{-1}{h-6}\\\\1(h-6) = 3(-1)\\\\h-6 = -3\\\\h = -3+6\\\\h = 3[/tex]

-----------------------------

Let's check the answer.

The point (h,-3) updates to (3,-3)

The claim is that the points (6,-2) and (3,-3) fall on a line with slope 1/3.

Use the slope formula to get the following:

[tex](x_1,y_1) = (6,-2) \text{ and } (x_2,y_2) = (3,-3)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{-3 - (-2)}{3 - 6}\\\\m = \frac{-3 + 2}{3 - 6}\\\\m = \frac{-1}{-3}\\\\m = \frac{1}{3}\\\\[/tex]

We get a slope of 1/3 as expected.

The answer is confirmed.

A slope of 1/3 means that each time you move up 1 unit (rise), move to the right 3 units (run).

The number of  items you would need to sell at your chosen price to break even is; 120 items

We are given the expression that represents the cost of producing x items as;

Cost of producing x units: C = 120 + 4x.

Now, we are told to decide on a selling price for each item. If we decide that the selling price for each item is $5, then it means that;

Revenue generated by selling x units at the rate of $5 per unit is;

R = 5x

For the chosen price to break even, it means that revenue must be equal to cost. Thus;

R = C

Thus;

5x = 120 + 4x

x = 120
