Given:

The graph passes through the given points (4,-2) and (2,0).

To find:

The quadratic function \(y=a(x-h)^2\).

Solution:

We have, quadratic function

\(y=a(x-h)^2\)            ...(i)

The graph passes through the given points (4,-2) and (2,0). It means the equation must be true for these points.

Putting x=4 and y=-2 in (i), we get

\(-2=a(4-h)^2\)         ...(ii)

Putting x=2 and y=0 in (i), we get

\(0=a(2-h)^2\)          ...(iii)

Divide (iii) by (ii).

\(\dfrac{0}{-2}=\dfrac{a(2-h)^2}{a(4-h)^2}\)

\(0=\dfrac{(2-h)^2}{(4-h)^2}\)

\(0=(2-h)^2\)

\(0=2-h\)

\(h=2\)

Putting h=2 in (ii), we get

\(-2=a(4-2)^2\)

\(-2=a(2)^2\)

\(-2=a(4)\)

Divide both sides by 4.

\(\dfrac{-2}{4}=a\)

\(\dfrac{-1}{2}=a\)

Putting \(a=-\dfrac{1}{2}\) and h=2 in (i), we get

\(y=-\dfrac{1}{2}(x-2)^2\)

Therefore, the required quadratic function is \(y=-\dfrac{1}{2}(x-2)^2\).

The appropriate regression model depends on the stationarity properties of both the dependent and independent variables, as well as the error term. The researcher can use a standard OLS regression model with first-order differencing of both Y and X.

In the first scenario, both Y and X are I(0), which means they are stationary time series. In this case, the researcher can perform a standard linear regression analysis, as the stationary series would lead to a stable long-run relationship. The answer from this model will be reliable and less likely to suffer from spurious regressions. In the second scenario, Y is I(2) and X is I(0). This implies that Y is integrated of order 2 and X is stationary. In this case, the researcher should first difference Y twice to make it stationary before performing a regression analysis. However, this approach might not be ideal as the integration orders differ, which can lead to biased results.

In the third scenario, Y and X are both I(1) and the error term is I(0). This indicates that both Y and X are non-stationary time series, but their combination might be stationary. The researcher should employ a co-integration analysis, such as the Engle-Granger method or Johansen test, to identify if there is a stable long-run relationship between Y and X. If co-integration is found, then an error correction model can be used for more accurate predictions.

Sally's z-score on a given measure is -2.5, where the mean is 5 and the standard deviation is 1.5:  Sally's raw score on the given measure is 1.25.

To find Sally's raw score, you can use the following formula:

Raw Score = (Z-score * Standard Deviation) + Mean

Given that Sally's Z-score is -2.5, the mean is 5, and the standard deviation is 1.5, you can plug these values into the formula:

Raw Score = (-2.5 * 1.5) + 5

Now, calculate the result:

Raw Score = (-3.75) + 5

Raw Score = 1.25

So, Sally's raw score on the given measure is 1.25.

It will take 15/2 hours for Mitch to run 1 mile. Cancelling out the common factors from numerator and denominator, the ratio reduces to 15/2.

Mitch ran 5/2 of a mile in 1/3 of an hour. To calculate how many hours it will take Mitch to run 1 mile, we need to use a ratio. The ratio is (5/2)/(1/3). To solve this, we need to multiply the numerator and denominator of the first fraction with the denominator of the second fraction, and then multiply the numerator and denominator of the second fraction with the denominator of the first fraction. So, the ratio becomes (5/2)*(3/1)/(1/3)*(2/1). Cancelling out the common factors from numerator and denominator, the ratio reduces to 15/2. This means that it will take 15/2 hours for Mitch to run 1 mile.

Answer:

20 % of n would be 12.8

Step-by-step explanation:

By first finding that 24.32 is 38% of 64. To find that you would have the fractions 38/100 = 24.32/n. From there you cross multiply the 100 times 24.32 then divide that answer by 38 to get the answer 64. you take that n=64 and find 20% of that which is 12.8.

The 20% of n is 12.8

38% of number n is given as:

\(38\% \times n = 24.32\)

Express the percentage (38%) as decimal

\(0.38 \times n = 24.32\)

Divide both sides of the equation by 0.38

\(n = 64\)

Multiply both sides of the equation by 20%

\(20\% \times n = 20\% \times 64\)

Express the percentage (20%) as decimal

\(20\% \times n = 0.20 \times 64\)

Evaluate the product

\(20\% \times n = 12.8\)

Hence, the 20% of n is 12.8

The given statement "A reaction that has K_eq = 2.0 × 10^(-8) will have high concentrations of products" is false because a low value of K_eq indicates a greater concentration of reactants compared to products.

The equilibrium constant, K_eq, represents the ratio of product concentrations to reactant concentrations at equilibrium. In this case, a K_eq value of 2.0 × 10^(-8) suggests that the concentration of products is significantly lower compared to the concentration of reactants.

This implies that the reaction favors the formation of reactants rather than products. Therefore, the statement is false as it states that the reaction will have high concentrations of products, which is contradictory to the low K_eq value provided.

The simplified radical expression by rationalizing the denominator is, \(\frac{-6}{\sqrt{5y}}\times\frac{\sqrt{5y}}{\sqrt{5y}}\) = \(\frac{-6\sqrt{5y}}{5y}$$\) = $\frac{-6\sqrt{5y}}{5y}$.

To simplify the radical expression by rationalizing the denominator, multiply both numerator and denominator by the conjugate of the denominator.

The given radical expression is \($\frac{-6}{\sqrt{5y}}$\).

Rationalizing the denominator

To rationalize the denominator, we multiply both the numerator and denominator by the conjugate of the denominator, \($\sqrt{5y}$\)

Note that multiplying the conjugate of the denominator is like squaring a binomial:

This simplifies to:

(-6√(5y))/(√(5y) * √(5y))

The denominator simplifies to:

√(5y) * √(5y) = √(5y)^2 = 5y

So, the expression becomes:

(-6√(5y))/(5y)

Therefore, the simplified expression, after rationalizing the denominator, is (-6√(5y))/(5y).

\($(a-b)(a+b)=a^2-b^2$\)

This is what we will do to rationalize the denominator in this problem.

We will multiply the numerator and denominator by the conjugate of the denominator, which is \($\sqrt{5y}$\).

Multiplying both the numerator and denominator by \($\sqrt{5y}$\), we get \(\frac{-6}{\sqrt{5y}}\times\frac{\sqrt{5y}}{\sqrt{5y}}\) = \(\frac{-6\sqrt{5y}}{5y}$$\)

The decision for this test at a .05 level of significance is not enough information to make a decision the correct answer is (d).

To make a decision for a hypothesis test, we compare the obtained test statistic (in this case, z = 1.80) with the critical value(s) based on the chosen level of significance (in this case, α = 0.05).

For a one-sample z test, if the obtained test statistic falls in the rejection region (i.e., beyond the critical value(s)), we reject the null hypothesis. Otherwise, if the obtained test statistic does not fall in the rejection region, we fail to reject the null hypothesis.

Without knowing the critical value(s) corresponding to a significance level of 0.05 and the directionality of the test (one-tailed or two-tailed), we cannot determine the decision for this test. Therefore, the correct answer is (d) There is not enough information to make a decision.

The intrinsic value of the PUT option is $0. It means the option has no inherent value based on the given information.

To determine the intrinsic value of a PUT option, we compare the strike price (X) with the current market price (S) of the underlying asset. If the strike price is higher than the market price, the intrinsic value is the difference between the strike price and the market price. However, if the market price is higher than the strike price, the intrinsic value is $0.

In the given information, we have the following data:

- Strike price (X): $90

- Market price (S): $47.78

Since the market price is lower than the strike price (47.78 < 90), the intrinsic value of the PUT option is $0. This means that exercising the option would not result in any profit because it is currently out of the money.

The coordinate matrix of x in the basis B' is [4, -1, 3, 2].

To find the coordinate matrix of x in the basis B', we need to express x as a linear combination of the basis vectors in B'.

Let's denote the coordinate matrix of x in the basis B' as Xb'. It will have the form:

Xb' = [a1]

     [a2]

     [a3]

     [a4]

To find the values of a1, a2, a3, and a4, we solve the equation:

x = a1 * (1, -1, 2, 1) + a2 * (1, 1, -4, 3) + a3 * (1, 2, 0, 3) + a4 * (1, 2, -2, 0)

Expanding the equation, we get:

(8, 9, -12, 2) = (a1 + a2 + a3 + a4, -a1 + a2 + 2a3 + 2a4, 2a1 - 4a2, a1 + 3a2 + 3a3)

Equating the corresponding components, we have the following system of equations:

a1 + a2 + a3 + a4 = 8 ...(1)

-a1 + a2 + 2a3 + 2a4 = 9 ...(2)

2a1 - 4a2 = -12 ...(3)

a1 + 3a2 + 3a3 = 2 ...(4)

To solve this system of equations, we can represent it in matrix form:

| 1 1 1 1 | | a1 | | 8 |

| -1 1 2 2 | * | a2 | = | 9 |

| 2 -4 0 0 | | a3 | | -12 |

| 1 3 3 0 | | a4 | | 2 |

We can solve this matrix equation to find the values of a1, a2, a3, and a4.

Solving the matrix equation, we find:

a1 = 4

a2 = -1

a3 = 3

a4 = 2

Therefore, the coordinate matrix of x in the basis B' is:

Xb' = [4]

[-1]

[3]

[2]

Hence, Xb' = [[4], [-1], [3], [2]].
