The proportion that could be used to find the width of Grace's model car is 1/2 = Model width / 12 inches.

To find the width of Grace's model car, a proportion can be set up using the lengths of the actual car and the desired model:

Proportion: Actual width / Actual length = Model width / Model length

Given values:

Actual length = 8 feet

Actual width = 4 feet

Model length = 12 inches

Converting the units:

12 inches = 1 foot (since 1 foot = 12 inches)

Substituting the values into the proportion:

4 feet / 8 feet = Model width / 12 inches

Simplifying the proportion:

1/2 = Model width / 12 inches

To find the model width, cross-multiply and solve for the unknown:

Model width = (1/2) * 12 inches = 6 inches

The possible value of positive constant b for an absolute maximum value of function g(x), [tex]g(x) = xe^{-x} + be^{-x} [/tex] at x = [tex] \frac{2}{3} [/tex] is equals to the [tex] \frac{1}{3} [/tex].

An absolute maximum point is a point where the function acquires its largest possible value. To drive the max or min absolute value, we have to substitute the derivative value of function equals to zero. We have a function, [tex]g(x) = xe^{-x} + be^{-x} [/tex], where b is positive constant. We have to determine the possible value of b for absolute maximum of g at x= 2/3.

Differentiating the function g(x) with respect to x

=> [tex]g'(x) = - x e^{-x} + e^{-x} - be^{-x} [/tex]

[tex]= (1 - x - b )e^{-x}[/tex]

[tex]= \frac{1 - x - b }{e^{x}}[/tex]

For obtaining absolute maximum value put, g'(x) = 0

=> [tex]\frac{1 - x - b }{e^{x}} = 0[/tex]

Substitute x = 2/3, in above expression,

[tex] \frac{1 - \frac{2}{3} - b }{e^{\frac{2}{3}}} = 0[/tex]

=> [tex]1 - \frac{2}{3} - b = 0[/tex]

We need to use some basic algebraic equations. Let's assume that the initial payment made by Frankie was x, and the total amount he has to pay for the computer is y. Also, let's assume that Frankie will make n monthly payments.

Now, we know that Frankie has already paid x, and he has to pay y-x more. Since he will pay this amount in n monthly installments, we can represent the monthly installment as (y-x)/n.

So, the equation that represents the relationship between n and y can be written as:

y = x + n*(y-x)/n

Simplifying this equation, we get:

y = x + y-x

y = y

This means that the equation is true for any value of n and y, as long as x is a valid initial payment amount. Therefore, the equation that represents the relationship between n and y is:

y = x + n*(y-x)/n

The equation we derived above is a simple but important concept in mathematics and finance. It shows us that we can calculate the total amount we need to pay for something by multiplying the monthly installment by the number of payments and adding the initial payment to it. This concept is used in many financial transactions, such as car loans, mortgages, and credit card payments.

Moreover, this equation also helps us to plan our finances and manage our budget effectively. We can use it to calculate how much we need to save every month to reach our financial goals, or to compare different payment options and choose the one that suits us best.

In conclusion, the equation that represents the relationship between the number of monthly payments and the total amount paid is an essential tool for anyone who wants to make wise financial decisions. By understanding this equation, we can save money, avoid debt, and achieve our financial goals more easily.

  q = 2

Step-by-step explanation:

You want to find q such that the difference between the two roots of 3x²-5x+q is 1/3.

In quadratic ax²+bx+c, the sum of the roots is (-b/a). For roots p and s, this tells us ...

  p + s = -(-5)/3 = 5/3

The problem statement tells us the difference is ...

  p - s = 1/3

Adding these two equations gives ...

  2p = (5+1)/3 = 2

  p = 1 . . . . . . . . . . . . . divide by 2

  s = p -1/3 = 2/3 . . . . find the smaller root

The product of the two roots is (c/a) = (q/3):

Step-by-step explanation:

To find f(x + h), we substitute x + h for x in the function f(x):

f(x + h) = (x + h)^2 + 2(x + h) + 1

Now we simplify by expanding the square:

f(x + h) = x^2 + 2hx + h^2 + 2x + 2h + 1

We can combine like terms to simplify this expression:

f(x + h) = x^2 + (2h + 2)x + (h^2 + 2h + 1)

Therefore, f(x + h) = x^2 + (2h + 2)x + (h^2 + 2h + 1).

Answer:

[tex]f(x+h) = x^2 + 2xh + h^2 + 2x+2h + 1[/tex]

Step-by-step explanation:

In this question, we have to plug (x + h) into the given function and simplify.

[tex]f(x) = x^2 + 2x + 1[/tex]

↓ replacing all instances of x with (x + h)

[tex]f(x+h) = (x+h)^2 + 2(x+h) + 1[/tex]

↓ expanding the quadratic term (x + h)²

[tex]f(x+h) = (x^2 + 2xh + h^2) + 2(x+h) + 1[/tex]

Exponential function, involves exponents. an exponential function has a constant as its base and a variable as its exponent but not the other way round (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function). An exponential function can be in one of the following forms.

In mathematics, an exponential function is a function of form f (x) = a^x, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0.

The research method that involves collecting data repeatedly on the same person as he or she ages is longitudinal.

Longitudinal research involves studying the same group of individuals over an extended period of time, typically years or even decades. This type of research allows researchers to collect data on changes in behavior, attitudes, or health outcomes over time, and can provide valuable information on the effects of age, development, or life events on these outcomes. Longitudinal research can be especially useful in studying developmental processes, as it allows researchers to track changes in individuals as they grow and develop.

However, longitudinal studies can also be expensive and time-consuming, as researchers must track and collect data from the same group of individuals over many years, and there is a risk of attrition or drop-out over time.

Answer:

x = 2, 6

Step-by-step explanation:

differentiate f(x) using the power rule

f'(a[tex]x^{n}[/tex] ) = na[tex]x^{n-1}[/tex] and f'( constant) = 0

given

f(x) = x³ - 12x² + 6x - 8

f'(x) = 3x² - 24x + 6

equate f'(x) to - 30

3x² - 24x + 6 = - 30 ( add 30 to both sides )

3x² - 24x + 36 = 0 ( divide through by 3 )

x² - 8x + 12 = 0 ← in standard form

(x - 2)(x - 6) = 0 ← in factored form

equate each factor to zero and solve for x

x - 2 = 0 ⇒ x = 2

x - 6 = 0 ⇒ x = 6

solution is x = 2, 6

The value of the standardized test statistic for this significance test is -1.3

For the standardized test statistic for this significance test, we need to compare the sample proportion to the hypothesized population proportion.

The null hypothesis (H₀)  

H₀: The proportion of patients missing a medical justification for opioid prescriptions at the hospital is equal to 30%.

The alternative hypothesis (H₁)

H₁: The proportion of patients missing a medical justification for opioid prescriptions at the hospital is different from 30%.

The sample size is 25 and 5 of those files are missing a medical,

The sample proportion (p) can be calculated as

(p) hat = (Number of files missing justification) / (Total number of files)

(p) hat = 5 / 25

(p) hat = 0.2

The standard error is given by

SE = √[((p) hat × (1 - (p) hat)) / n]

SE = √[(0.2 × (1 - 0.2)) / 25] = √(0.16 / 25) = 0.08

For the standardized test statistic, we use the formula:

z = ((p) hat - p₀) / SE

where p₀ is the hypothesized population proportion.

p₀ = 30% = 0.3

z = (0.2 - 0.3) / 0.08 = -0.1 / 0.08 = -1.25 = -1.3

an equation to represent the relation is,

We know that,

Proportion is extensively explained. Proportion is mostly discussed using ratios and fractions. A fraction is written as a/b, while a ratio is represented as a:b, and a proportion states that two ratios are equal. In this case, a and b can be any two integers. The ratio and proportion are important foundations for understanding numerous ideas in mathematics and science.

Since, The relation represents an inverse variation because as the values of x is increasing the values of y is decreasing.

Hence, We can formulate;

y = k/x

Plug y = 5, x = 2;

5 = k/2

Solve for k;
