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

(A) The angular speed of the wheel in radians per minute is 3.78 radians per minute.

(B) The linear speed of a passenger in miles per hour is 4.09 miles per hour.

Angular speed is the rate at which an object rotates, measured in radians per unit of time. The unit of radians is commonly used in circular motion problems because it allows us to express angles and rotational motion in a consistent way. Linear speed, on the other hand, is the rate at which an object moves in a straight line, measured in units of distance per unit of time.

(A) To find the angular speed of the Ferris wheel in radians per minute, we first need to convert the given rate of revolutions per hour to revolutions per minute. We can do this by dividing the rate by 60 since there are 60 minutes in an hour. Therefore, the wheel completes

=> 100/60 = 5/3 revolutions per minute.

Next, we need to find the angle that the wheel turns in one minute, which we can do by dividing a full rotation (360 degrees) by the number of revolutions per minute. In this case, the angle turned in one minute is

=> (360 degrees)/(5/3 revolutions per minute) = 216 degrees per minute.

To convert this angle to radians, we multiply by (π/180) since there are π/180 radians in one degree. This gives us an angular speed of

=> (216 * π/180) = 3.78 radians per minute.

(B) Using these values, we can calculate the linear speed of the passenger as follows:

Linear speed = (distance traveled)/(time taken) = (π * 72 feet)/(1/5 minutes) = (π * 72 * 5 feet/minute) = (360 * π feet/minute)

To convert this speed to miles per hour, we divide by the number of feet per mile (5280) and multiply by the number of minutes per hour (60), giving us:

Linear speed = (360 * π feet/minute)/(5280 feet/mile) * (60 minutes/hour) = 4.09 miles per hour (rounded to two decimal places).

Therefore, the linear speed of the passenger on the Ferris wheel is approximately 4.09 miles per hour.

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

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

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).

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]

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.

Answer: DESMOS

Step-by-step explanation:

Your OHVA teacher reminded you in class to use DESMOS to see the graph and then sketch it on your test...

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

     0.6 = k

So the final answer is: P(x) = 0.6 · (x-2)^2 · (x-0) · (x+2)

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.
