URGENT DUE IN 10 MINS Suppose that the function f(x) = 5.32 + 0.80x represents the cost of mailing an object that weighs x pounds. How much would it cost mail an object that weighs 36 pounds?

solution of the linear equation is x = (2a - 16)/ 3 and y = - (a+16)/ 9

An algebraic expression that shows a relationship between two variables   that have only first order term. One of the main criteria for linear equation is that we get a straight line when plot this equation in a coordinate system.

.

we are given, two linear equations x - a -3y = 0

and a - 2x -3y - 16 =0

from the first equation, x = a + 3y

we put the value of x in the second equation, a - 2(a +3y) - 3y -16= 0

                                                                     a - 2a - 6y - 3y -16 = 0

                                                          - a - 9y -16 =0

                                                   - (a + 16) = 9y

                                              y = - (a+16) / 9

now we put the value of y in the equation, x = a + 3y

                                    get, x = a+ 3 [ - (a+16)] / 9

                                      x = a + [ - (a+16)] / 3

                                          x = (3a - a -16) / 3

                              x = (2a - 16)/ 3

The sampling technique that was used when an insurance company divides the population of drivers into three groups (under 25 years of age, 26-64 years of age and over 65 years of age) and randomly selects a sample of 150 drivers under 25 years of age, a sample of 300 drivers aged 26-64 and a sample of 200 drivers over 65 years of age is stratified sampling.

Stratified sampling is a method used in statistics in which the population is divided into smaller groups known as strata. Samples are then chosen from each stratum in the same proportion as the stratum appears in the overall population to make up the final sample size.This technique is used to ensure that the sample selected is a representative of the population. Stratified sampling technique is also useful in situations where the population is heterogeneous in nature and contains groups that differ widely from each other, as in this case with the drivers being divided into age groups.

The relative maxima and the relative minima occur at x=-2 and x= 2 respectively

The function is y = (x^3) -12x+3 We need to find the relative maxima and minima. To find the relative maxima and minima, we need to follow the following steps:

The function y = (x^3) -12x+3dy/dx = 3x^2 -12

The first derivative of the function is 3x^2 -12

Equating first derivative to zero3x^2 -12 = 0x^2 -4 = 0x^2 = 4x = ± 2

Now, we will find the value of y at x = 2 and x = -2 using the second derivative test to know whether it is maxima or minima.

Second derivative of the functiond^2y/dx^2 = 6x

The second derivative of the function is 6x.

At x = -2, d^2y/dx^2 = 6(-2) = -12. Since the second derivative is negative, it is a relative maximum.At x = 2, d^2y/dx^2 = 6(2) = 12. Since the second derivative is positive, it is a relative minimum.

∴ The relative maxima occur at x= -2, and the relative minima occur at x= 2.

Thus, the correct answer is option A: The relative maxima occur at x=-2. The relative minima occur at x=2.

The expectation of getting correct option out of total choice of 5 question.

Probability is the ratio of number of favorable outcomes to the total number of outcomes.It can not be more than 1.

we have five question each of them has four choice, two out of them are correct.

Number of correct choice in one question = 2

Total number of choice in a question = 4

probability to get correct option of one question = 2/4 = 0.5.

Then the probability of 5 question = 5(0.5) = 2.5

Thus, the expectation of correct choice is 2.5.

Fred Meyer's unit Rate: $2.17 per pound.

Costco's unit Rate: $2.10 per pound.

Better Price:​  Costco has the better price for cheddar cheese.

To determine who has the better price for cheddar cheese, let's calculate the unit rate for both Fred Meyer and Costco.

Fred Meyer:

Cheddar cheese is priced at $6.50 for 3 pounds. To find the unit rate, we divide the price by the quantity: $6.50 ÷ 3 pounds = $2.17 per pound.

Costco:

Costco offers 10 pounds of cheddar cheese for $21. To find the unit rate, we divide the price by the quantity: $21 ÷ 10 pounds = $2.10 per pound.

Comparing the unit rates, we can see that Fred Meyer's cheddar cheese is priced at $2.17 per pound, while Costco's cheddar cheese is priced at $2.10 per pound.

Therefore, based on the unit rates, Costco has the better price for cheddar cheese. They offer it at a slightly lower price per pound compared to Fred Meyer. Customers can save $0.07 per pound by purchasing cheddar cheese from Costco instead of Fred Meyer.

However, it's important to note that price isn't the only factor to consider when deciding where to purchase cheddar cheese. Other factors such as location, quality, convenience, and personal preferences should also be taken into account.

Additionally, it's always a good idea to compare prices and consider any ongoing promotions or discounts that might affect the final decision.

Answer:

\(\boxed{\tt a=9}\)

Step-by-step explanation:

We are given the equation:

\(-5a+7= -38\)

We want to solve for a, so we must isolate a on one side of the equation.

7 is being added to -5a. The inverse of addition is subtraction. Subtract 7 from both sides of the equation.

\(-5a+7-7=-38-7\)

\(-5a=-38-7\)

\(-5a=-45\)

a is being multiplied by -5. The inverse of multiplication is division. Divide both sides of the equation by -5.

\(\frac{-5a}{-5} =\frac{-45}{-5}\)

\(a=\frac{-45}{-5}\)

\(a=9\)

Let's check our solution. Plug 9 in for a.

\(-5a+7=-38\)

\(-5(9)+7=-38\)

\(-45+7=-38\)

\(-38=-38\)

This checks out, so we know our solution a=9 is correct.

-5a +7 =-38

-5a +7 (-7) = -38 (-7)

-5a= -45

-5a (÷-5)= -45 (÷-5)

a= 9

The amount of mold after n days is 3 × (1.5)ⁿ⁻¹.

Geometric progression is a sequence of numbers such that the ratio of two consecutive numbers is the same for whole sequence.

This ratio is common ratio.

At first, mold was 3 cm², then 4.5 cm², and it was increasing each day by 50%.

a₁ = 3

a₂ = 4.5

a₃ = 4.5 + (4.5 × 50%) = 6.75

.............

Here the common ratio, r = a₂/a₁ = a₃/a₂ = ..... = 1.5

n th term of a GP = a rⁿ⁻¹, where a is the first term and r is the common ratio.

Area of mold after n days = 3 × (1.5)ⁿ⁻¹

Hence the mold at any time can be calculated by the formula 3 × (1.5)ⁿ⁻¹.
