He would pay $8500 interest if he can afford payments of $425 per month and can borrow the money at an interest rate of 4% compounded monthly for 5 years.

The expense of borrowing money is interest. It equates to a fee or additional charge the borrower pays the lender for the loaned amount, and is sometimes stated as a percentage. When you make a payment on a loan with simple interest, the money first goes toward the interest for that month and the rest is applied to the principal. Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time. Contrary to compound interest, where we add the interest of one year's principal to the next year's principal to compute interest, the principal amount under simple interest remains constant.

Given,

Principal = $425

Rate = 4%

Time = 5 years

Interest = Principal × Rate × time

Interest:

= 425 × 4×5

= 8500

Domain of {(0, −2), (-3, 1), (-4, 3), (1, −4)} is (0, -3, -4, 1) and range of

{(0, −2), (-3, 1), (-4, 3), (1, −4)} is (-2, 1, 3, -4).

The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values. In order to identify the values of the independent variable x and acquire the domain, we simply solve the equation y = f(x). Simply put, x=g(y) will calculate the function's range after we identify g's domain (y).

Given,

{(0, −2), (-3, 1), (-4, 3), (1, −4)}

The set of all x coordinates makes up the domain, while the set of all y coordinates makes up the range.

Domain = (0, -3, -4, 1)

Range = (-2, 1, 3, -4)

Domain of {(0, −2), (-3, 1), (-4, 3), (1, −4)} is (0, -3, -4, 1) and range of

The equation of the line is y = -68.7x - 5.1 when the slope is 68.7 and the y - intercept is -5.1.

Equation of the line

Basically, the equation of the line refers the mathematical equation that gives the relation between the coordinate points lying on that straight line.

The general form of the equation of the line is

y = mx + c

where

m refers the slope

c refers the y intercept

Given,

Here we have the value of slope is -68.7 and the y intercept is -5.1.

Now, we have to write the equation of the line.

Here we have the value of

Slope = -68.7

y- intercept = - 5.1

So, the equation of the line is written as,

=> y =-68.7x - 5.1

Therefore, the equation of the line with the given slope and intercept is

y = -68.7x -5.1

i is expression is equivalent to i233.

Given i233

We know that i2 = -1 , if we square (i2) we get (-1)2 = 1

So, if i is multiplied to (i2), we get i3 = (-1).i = -i

Again if i is multiplied to i3 , we get i4 = (-i).i = -i2 = -(-1) = 1

Hence, all even powers of i after 2, will give answer as 1

The sequence will continue as a cycle as i, -1, -i, 1

So, i233 can be rewritten as i232 + 1= i232.i

i233 = (i2)116 .i = (-1)116 . i

Since the power 116 is even , the term becomes 1.i = i

The perimeter of a face of a cube is 60m that has volume 125 m³.

The total number of cubic units that a cube occupies in three dimensions is its volume. Six faces, twelve edges, and eight vertices make up the three-dimensional shape of a cube. Therefore, the area encircled by a cube's six faces is considered to equal its volume. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity. The volume of a cube can be calculated by three times multiplying the edge length.

Given,

Volume of cube = side³

Volume = 125 m³

side³ = 125m³

Side = ∛125

Side = 5

Perimeter of cube = 12 × Side

= 12 × 5

After 4.6 years the car's worth will be $10,600 or less.

According to the question,

We have the following information:

A car is purchased for $38,000. Each year it loses 20% of its value.

Now, we will first find 20% of 38,000:

(20*38000)/100

$7600

Now, each year the decrease in the price will be $7600.

So, we have the following arithmetic progression:

38000, 30400, ...

Now, following formula is used to find the nth term of an A.P:

an = a+(n-1)d where a is the first term and d is the common difference

10,600 = 38000+(n-1)-7600

10600-38000 = -7600n+7600

-27,400 = -7600n+7600

-7600n = -27400-7600

-7600n = -35000

n = 35000/7600

n = 4.6 years

Hence, after 4.6 years the car will be worth $10,600 or less.

For the functions in this problem, we have that:

Hence the functions are given as follows:

The time at which they have the same amount is x for which:

P(x) = J(x)

65 - 2.5x = 20 - x

1.5x = 45

x = 45/1.5

x = 30 seconds.

However, at this time, the amount would be of:

J(30) = 20 - 30 = -10.

Which is a negative amount of water, not possible, hence they would have the same amount when Jason finishes, hence:

65 - 2.5x = 0

2.5x = 65

x = 65/2.5

x = 26 seconds.

The decrease of the population from the question can be modeled by;

P = 92000e^-0.02t

We know that the population of a place can be modeled by the use of an exponential model. In the exponential model, there could be an increase or  decrease in the population of a place as the case may be. In this case, we are told that there is a decrease in the population of the place.

Let us note from the question that we have been told that every year after 2010, the population decreased by 2% due to heavy population. We were also made to understand in the question that the initial population of the city is about 92000.

Now, we can write the model as;

P = Poe^-rt

P = population of the area at time t

Po = population initially present

r = rate of population decrease

t = time taken since 2010.

Step-by-step explanation:

The given scenario can be modelled using the linear equation:

[tex]y=mx+b[/tex]

where:

Mindy initially owns 20 pairs of shoes. Therefore, the initial value is b = 20.

If Mindy purchases 2 pairs but destroys 1 pair each week, then she is gaining 1 pair of shoes each week.  Therefore, the rate of change is m = 1.

Therefore, the equation is:

[tex]y=x+20[/tex]

where:

To find how long it will take for Mindy's closet to have 50 pairs of shoes, substitute y = 50 into the equation and solve for x:

[tex]\implies 50=x+20[/tex]

[tex]\implies 50-20=x+20-20[/tex]

[tex]\implies 30=x[/tex]

[tex]\implies x=30[/tex]
