Step-by-step explanation:

The point B and C are opposite to each other.

A number line is a mathematical visual representation of numbers on a straight line. The digits on a number line are positioned sequentially at regular intervals throughout its length. It frequently appears horizontally and might go on forever in any direction.

As seen from the number line, point A is one unit left of -1 which is -2. Since each mark is a difference of 1 and to the left is a negative value, point B is midway between -1 and 0 is half of -1 which is -0.5, point C is midway between 0 and 1 is basically half of 1 which is 0.5 and point D is halfway between 1 and 2 is exactly that 1.5

As per the numerical values of the given points, the two that are opposites to each other are points B and C. They both have a value of 0.5 on each end of the number line, one being negative while the other is positive, thus they are opposites of each other.

Therefore, points B and C are opposite to each other.

Answer:

y = x + 20

30 weeks

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]

Therefore, it will take Mindy 30 weeks to have 50 pairs of shoes in her closet.

The time at which the two bottles will have the same amount of water, using linear functions, is of:

26 seconds.

The slope-intercept representation of a linear function is given by the rule shown as follows:

y = mx + b

The coefficients of the function and their meaning are described as follows:

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 problem is:

Jason's water bottle has 20 ounces of water, and he is drinking ata rate of 1 ouncer per second. Pedro's water bottle contains 65 bunces of water, and he is drinking at a rate of 2.5 ouncers per second. At how many seconds, s, will the two bottles have the same amount of water if Jason and Pedro start drinking from each of their bottles at the same time?

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.

We can now write;

P = 92000e^-0.02t

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

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.

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

Therefore, i233 = 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

The car's cost 3 years ago was $22,045.45.

According to the question,

We have the following information:

A new car costs $24,250, which is approximately 110% of what a comparable car cost 3 years ago.

Now, let's take the cost of car 3 years to be $x.

So, we have the following expression:

110% of x = 24250

110x/100 = 24250

Using the cross multiplication method:

110x = 24250*100

Dividing both sides by 110 will give us the value of x which is the required cost of car:

x = 2425000/110

x = $22045.45

Hence, the car's cost 3 years ago was $22,045.45.

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.
