We can see that the exponential model is better

The main difference between a linear and an exponential function is the way they change as their input variable (usually denoted as x) increases.

In summary, linear functions have a constant rate of change, while exponential functions have an increasing rate of change.

For the linear function;

f(x) = 946(6) + 3349

= 9025

For the exponential function;

g(x) = 3866e^0.138(6)

g(x) = 8848

The investments are $ 4000 and $ 3000 in the respective accounts

The mathematical field of algebra assists in the depiction of problems or conditions as mathematical statements. It involves variables like x, y, z, and mathematical operations like addition, subtraction, multiplication, and division to form a meaningful mathematical expression.

In the given question,

x = amount invested at 10 %

( 7000 - x ) = amount invested at 11 %

The total interest was $730 :

.10 (x) + .11 (7000-x) = 730

0.1 x + 770 - 0.11 x = 730

0.01 x = 40

x = 4000

Therefore, the amount invested in an account that pays 10 % per year is $ 4000.

Hence ,  the amount invested in an account that pays 11 % per year is

= ( 7000 - x ) = 7000 - 4000 = $ 3000.

7/8 of sixteen times a half of 30 is 210.

What is a PEMDAS rule?

PEMDAS is an acronym that stands for the order of operations in mathematics: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

To calculate this, we can follow the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction):

Start with the expression inside the parentheses: half of 30 is 15.

Multiply 16 by 15: 16 times 15 is 240.

Find 7/8 of 240:

7/8 of 240 = (7/8) x 240

                  = 210

Hence, 7/8 of sixteen times a half of 30 is 210.

If a value of "y" is greater than 10, then it is a solution to the inequality 10 < y. If it is less than or equal to 10, then it is not a solution.

What is inequality?

In mathematics, an inequality is a statement that describes a relationship between two values, expressing that one value is greater than, less than, or equal to the other value. Inequalities are denoted by symbols such as "<" (less than), ">" (greater than), "≤" (less than or equal to), "≥" (greater than or equal to), or "≠" (not equal to).

The inequality 10 < y means that "y" is greater than 10. To determine whether a given value of "y" is a solution to this inequality, we simply need to check whether that value is indeed greater than 10.

For example:

If y = 11, then 10 < y is true, because 11 is greater than 10.

If y = 10, then 10 < y is false, because 10 is not greater than 10 (they are equal).

If y = 9, then 10 < y is false, because 9 is not greater than 10.

Hence, if a value of "y" is greater than 10, then it is a solution to the inequality 10 < y. If it is less than or equal to 10, then it is not a solution.

Using the formula of simple interest, the time it will take to accumulate to $3200 at a rate of 4.5% is 71.35 years

Simple interest is a method of calculating the interest charge on a loan or deposit. It is based on the principle of earning interest only on the initial amount (principal) that was borrowed or deposited.

The formula for simple interest is:

I = P * r * t

where:

I is the interest amount

P is the principal amount

r is the interest rate (expressed as a decimal)

t is the time period (in years)

Substituting the values into the formula;

A = P(1 + rt)

3200 = 760(1 + 0.045(t))

3200 = 760 + 34.2t

34.2t = 3200 - 760

34.2t = 2440

t = 2440 / 34.2

t = 72.35 years

Answer:

Step-by-step explanation:

To find the value of x such that f(x) = g(x), we need to set the two functions equal to each other and solve for x.

First, let's define the variables:

f(x) = 2x² - x - 6 is a quadratic function with x as the variable.

g(x) = x² - 4 is also a quadratic function with x as the variable.

Now, to find the value of x such that f(x) = g(x), we set the two functions equal to each other:

2x² - x - 6 = x² - 4

Next, we simplify this equation by subtracting x² from both sides:

x² + x - 10 = 0

This is a quadratic equation, which we can solve for x using either the quadratic formula or by factoring.

Let's try factoring:

x² + x - 10 = (x + 5)(x - 2) = 0

So either x + 5 = 0 or x - 2 = 0. Solving for x, we find that:

x = -5 or x = 2

These are the two values of x such that f(x) = g(x).

-1/10 should be subtracted from 1/2 to get 4/10.

(x) = 4/10 - 1/2

(x) = 4/10 - 5/10

(x) = -1/10

Answer:

285.76 kilograms       1.1 cubic yard

Step-by-step explanation:

Answer:

1.11121 cubic yards.

Step-by-step explanation:

First, let's convert the weight of 1 bag of garden soil from pounds to kilograms:

1 lb = 0.45359237 kg

42 lbs = 42 * 0.45359237 kg = 19.05 kg

So, the weight of 1 bag of garden soil is 19.05 kilograms.

Next, let's find the weight of 15 bags of garden soil:

15 bags * 19.05 kg/bag = 285.75 kg

So, 15 bags of garden soil weigh 285.75 kilograms.

Next, let's find the volume of 15 bags of garden soil in cubic yards:

1 cubic foot = 0.037037 cubic yards

2 cubic feet * 15 bags = 30 cubic feet

30 cubic feet = 30 * 0.037037 cubic yards = 1.11121 cubic yards

So, 15 bags of garden soil have a volume of 1.11121 cubic yards.

The distance between 0 and -7 is 7 units, since 0 is 7 units to the right of -7.

The absolute value of -7 is 7, since the absolute value of a number is its distance from 0 on the number line.

The magnitude of -7 is also 7, which is the same as its absolute value. The magnitude of a number refers to its size or absolute value, regardless of its sign. In this case, the magnitude of -7 is 7.

a) The required margin of error and lower and upper limits are:-

E =0.124

Lower limit =3.026

Upper limit =  3.274

b) sample size is n = 27.

An estimated range for an unknown parameter is known as a confidence interval. The 95% confidence level is the most popular, however other levels, such as 90% or 99%, are occasionally used when computing confidence intervals.

The margin of error will be calculated as:-

a) Margin of error (E) :

[tex]E = Z_c\times \dfrac{\sigma}{\sqrt{n}}[/tex]

E =0.124

Margin of error = E =0.124

The lower and upper limits are calculated as:-

Lower limit = x-E

L= 3.15 - 0.124

L= 3.026

Lower limit =3.026

Upper limit = x + E

U= 3.15 + 0.124

U= 3.274

Upper limit =  3.274

b) The following equation may be used to calculate the right number of samples, n when is already known:

Margin of error = 0.13

Sample size (n):

[tex]n = (\dfrac{Z_c\sigma}{E})^2[/tex]

If "a" is a root of a polynomial, then (x-a) is a factor of the polynomial.

If the multiplicity of a root a is "p", then (x-a)^p is a factor of the polynomial.

Based on the roots and multiplicity, we have:

    P(x) = k · (x-2)^2 · (x-0) · (x - (-2))

    P(x) = k · (x-2)^2 · (x-0) · (x+2)

We need that "k" up front to account for any vertical stretch or compression to hit the exact point (5,189).

To find "k", we plug in that point and solve for "k":

     189 = k · (5-2)^2 · (5-0) · (5+2)

     189 = k · (3)^2 · (5) · (7)

     189 = k · 315

Answer:

he weight of 15 bags of garden soil in kilograms is 285.75 kilograms, and the volume of 15 bags in cubic yards is 1.111 cubic yards.

Step-by-step explanation:

To find the weight of 15 bags in kilograms, we can first convert the weight of one bag from pounds to kilograms and then multiply by the number of bags:

1 pound = 0.453592 kilograms

So the weight of one bag in kilograms is:

42 pounds * 0.453592 kilograms/pound = 19.05 kilograms

The weight of 15 bags in kilograms is:

15 bags * 19.05 kilograms/bag = 285.75 kilograms

To find the volume of 15 bags in cubic yards, we can first convert the volume of one bag from cubic feet to cubic yards and then multiply by the number of bags:

1 cubic yard = 27 cubic feet

So the volume of one bag in cubic yards is:

2 cubic feet / 27 cubic feet/cubic yard = 2 / 27 = 0.07407 cubic yards

The volume of 15 bags in cubic yards is:

15 bags * 0.07407 cubic yards/bag = 1.111 cubic yards

Therefore, the weight of 15 bags of garden soil in kilograms is 285.75 kilograms, and the volume of 15 bags in cubic yards is 1.111 cubic yards.

Reginald used 2 square tiles to make the mosaic

An equation is an expression that shows how numbers and variables are linked together using mathematical operations such as addition, subtraction, multiplication and division.

The area is the product of the length and width. Hence:

Area = length * width

Reginald created a mosaic from 6" square tiles. Therefore:

Area of tiles = 6 in * 6 in = 36 in²

If the completed mosaic was 2 feet by 3 feet, Hence:

Area of mosaic = 2 feet * 3 feet = 6 feet

1 feet = 12 in

6 feet = 6 feet * 12 in per feet = 72 in²

Number of tiles = Area of mosaic / area of tiles = 72 in² / 36 in² = 2
