The solution to the system of equations is (1/2, 5).

The elimination method involves manipulating these equations to eliminate one of the variables. This is done by multiplying one or both of the equations by a constant so that the coefficients of one of the variables are equal in both equations, but with opposite signs. The equations are then added or subtracted, depending on the signs, to eliminate one of the variables.

To solve the system of equations by elimination, we can follow these steps:

Multiply the first equation by 2 to get rid of the y-term:

16x + 14y = 78

Add the second equation to the new equation to eliminate the y-terms:

16x + 14y + 4x - 14y = 78 - 68

20x = 10

Solve for x:

x = 1/2

Substitute x = 1/2 into the first equation to solve for y:

8(1/2) + 7y = 39

4 + 7y = 39

7y = 35

y = 5

Check the solution by substituting both x = 1/2 and y = 5 into both original equations:

8(1/2) + 7(5) = 39 (true)

4(1/2) - 14(5) = -68 (true)

Therefore, the solution to the system of equations is (1/2, 5).

The smallest possible value of x+y+z such that 3^x+5^y+7^z is divisible by 105 is 11.

Natural numbers are a set of positive integers that are used for counting and ordering. In other words, natural numbers are the set of numbers that are used to represent the quantity of objects, such as 1, 2, 3, 4, 5, 6, and so on. Some definitions include zero as a natural number, while others define natural numbers to start from 1. In mathematics, natural numbers are denoted by the symbol "N" or "N+", and are sometimes referred to as counting numbers.

Whole numbers are a set of non-negative integers that include all natural numbers (positive integers) and zero. Whole numbers are used to represent quantities that cannot be divided into smaller parts, such as the number of people in a room, the number of apples in a basket, or the number of books on a shelf.

In the given question,

We know that 105 is a multiple of 3, 5, and 7. Therefore, if 3^x+5^y+7^z is divisible by 105, it must also be divisible by 3, 5, and 7.

If 3^x+5^y+7^z is divisible by 3, then 3^x ≡ 0 (mod 3), which means x ≥ 1.

If 3^x+5^y+7^z is divisible by 5, then 5^y ≡ 0 (mod 5), which means y ≥ 1.

If 3^x+5^y+7^z is divisible by 7, then 7^z ≡ 0 (mod 7), which means z ≥ 1.

Therefore, we have x+y+z ≥ 3.

We also know that 105 is the smallest multiple of 3, 5, and 7. Therefore, we want to find the smallest values of x, y, and z that will make 3^x+5^y+7^z divisible by 105.

If we want 3^x+5^y+7^z to be divisible by 105, we need x, y, and z to be multiples of 4, 4, and 3, respectively.

The smallest such values are x=4, y=4, and z=3. Therefore, the smallest possible value of x+y+z is 4+4+3=11.

So, the smallest possible value of x+y+z such that 3^x+5^y+7^z is divisible by 105 is 11.

The probability that the next person will purchase no costume is 80%.

What is the difference between a probability and an odds?

The possibility of an event occurring can be expressed using odds and probability, but they are computed and understood in different ways.

Probability, which is stated as a number between 0 and 1 (or between 0% and 100%), is the possibility that an event will occur. By dividing the number of positive possibilities by the total number of potential outcomes, the probability of an event happening is determined.

The possibility of an event happening is expressed differently by odds, which are expressed as a ratio of the number of favourable events to the number of negative outcomes. It is possible to state odds as "odds for" or "odds against."

Now,

The total number of visitors who purchased costumes is:

71 (exactly one) + 12 (more than one) = 83

The total number of visitors who did not purchase a costume is: 349

The probability that the next person will purchase no costume is:

349 / (349 + 83) = 349 / 432 ≈ 0.8079

Hence, the probability that the next person will purchase no costume is 80%.

Answer:

We can solve this integral using the u-substitution method.

Let u = 3x, then du/dx = 3 and dx = du/3.

Substituting these values, we get:

∫2x * 2/3x dx = ∫4/3 du

Integrating, we get:

= (4/3)u + C

Substituting back u = 3x, we get:

= (4/3)(3x) + C

= 4x + C

Therefore, the solution to the integral ∫2x * 2/3x dx is 4x + C.

Remember, a negative times a negative equals a positive

Step-by-step explanation:

Since u and w are orthogonal, their dot product is 0. Thus,

u · w = 0

Using the Pythagorean Theorem,

||u - w||^2 = ||u||^2 + ||w||^2 - 2(u · w)

Since u and w are unital (i.e., their lengths are 1), we have

||u||^2 = ||w||^2 = 1

Substituting these values and u · w = 0, we get

||u - w||^2 = 1 + 1 - 0 = 2

Taking the square root of both sides, we get

||u - w|| = √2

Therefore, we have shown that if u and w are unital orthogonal vectors, then ||u - w|| = √2.

1.

  (a)Decay

  (b) [tex]y=a(1-r)^{x}[/tex]

       r = rate of decay, a is the initial value

       1-r=0.57 = r=1-0.57 = r = 0.43

  (c) a = 35

  (d) [tex]y=35(0.57)^{3}\\\\y=35(0.185193)\\y=6.481755[/tex]

2.

   (a) Growth

   (b)[tex]y=a(1+r)^{x} \\[/tex]

        r = rate of growth, a is the initial value

         1+r=1.23 = r=1+1.23 = r = 2.23

   (c) a = 225

   (d) [tex]y=225(1.23)^{2} \\y=225(1.5129)\\y=340.4025[/tex]

Problem 1

Set the base of the exponent equal to 1+r and solve for r.

1+r = 0.57

r = 0.57-1

r = -0.43

The result is negative, which tells us we have exponential decay. Notice that b = 0.57 fits the interval 0 < b < 1.

The rate of decay is 43%

The initial value is a = 35 since this is the first value mentioned in the equation. Plugging x = 0 into the equation will lead to y = 35.

Let's now plug in x = 3

y = 35*(0.57)^x

y = 35*(0.57)^3

y = 35*0.185193

y = 6.481755

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

======================================================

Problem 2

We'll follow similar steps as problem 1.

1+r = 1.23

r = 1.23-1

r = 0.23

The r value is positive, so we have growth this time. Notice that b = 1.23 fits the interval b > 1.

The growth rate is 23% since r = 0.23 converts to this.

The initial value is a = 225. Compare y = a(1+r)^x to y = 225(1.23)^x to see how the terms match up. If you want you can think of it like y = 225(1+0.23)^x. Plugging x = 0 into the equation will lead to y = 225.

Let's plug in x = 2.

y = 225*(1.23)^x

y = 225*(1.23)^2

y = 225*1.5129

y = 340.4025

Amount of money do you need to save to purchase the home is  $15,000. The total amount the bank will be loaning you is $235,000.  You can expect to pay around $1,332.29 per month.

A down payment is a payment made upfront when purchasing a large ticket item, such as a home or a car. It is a percentage of the total purchase price that the buyer pays out of their own pocket, with the remainder of the price financed through a loan.

To calculate the down payment, we need to multiply the purchase price by the percentage:

Down payment = 0.03 x $250,000 = $7,500

To calculate the closing costs, we also need to multiply the purchase price by the percentage:

Closing costs = 0.03 x $250,000 = $7,500

So the total amount of money needed to purchase the home is the sum of the down payment and the closing costs:

Total cost = $7,500 + $7,500 = $15,000

The amount the bank will be loaning you is the purchase price minus the down payment and the closing costs:

Loan amount = $250,000 - $15,000 = $235,000

To calculate the monthly payments, we need to use the formula for a fixed-rate mortgage:

M = P [ i(1 + i)ⁿ ] / [ (1 + i)ⁿ⁻¹]

where:

M = monthly payment

P = loan amount

i = monthly interest rate (5.5% / 12 = 0.0045833)

n = total number of payments (30 years x 12 months = 360)

Plugging in the numbers, we get:

M = $235,000 [ 0.0045833(1 + 0.0045833)³⁶⁰ ] / [ (1 + 0.0045833)³⁶⁰ – 1]

M ≈ $1,332.29

So you can expect to pay around $1,332.29 per month for 30 years to pay off the mortgage.

It would cost N125.00 to furnish a square room of 5m at N5.00 per square meter.

A square meter is a unit of measurement that denotes the surface area of a two-dimensional object or surface that is one metre long and one meter broad. It is frequently used to determine the dimensions of rooms, structures, and other areas as well as the surface area of land or other objects. The imperial method of measurement converts one square metre into 10.764 square feet. Science, engineering, and other fields frequently utilise the square metre, a core unit of the International System of Units (SI).

The area of the room is:

Area = 5m x 5m = 25 square meters

Then, we multiply the area by the cost per square meter:

Cost = 25 square meters x N5.00 per square meter = N125.00

we can estimate that about 7632 people in the city have visited the city's community garden.

Step-by-step explanation:

You can use a proportion to estimate the number of people in the city who have visited the city's community garden. The proportion is:

(Number of people in the city who have visited the community garden) / (Total number of people in the city) = (Number of people in the sample who have visited the community garden) / (Total number of people in the sample)

We can plug in the values given in the problem to get:

(x) / (14200) = (43) / (80)

To solve for x, we can cross-multiply and simplify:

80x = 14200 * 43

x = (14200 * 43) / 80

x ≈ 7632

Therefore, we can estimate that about 7632 people in the city have visited the city's community garden.

The role of GCF, its placement and verification has been explained below. The solution has been obtained by using the concept of Greatest Common Factor.

The greatest common factor, or largest number, is the product of two or more numbers (GCF). The greatest number (factor) that separates them yields a natural number.

1. The GCF is a factor that all terms in a polynomial share.

For instance, if the polynomial has the form R * S + R * T, the GCF is R because both terms share the factor R.

2. The GCF is positioned in front of the remaining polynomials, outside of the parenthesis, once we have factored out the GCF.

R * S + R * T, given the prior example, is R (S + T).
