The correct answer is the graph shifts 2units up to formed the given function.

When we say that the graph of f(x) is shifted 2 units up, it means that every point on the graph is moved vertically upwards by a distance of 2 units.

If the original graph of f(x) had a point (x, y), after shifting it 2 units up, the new point on the translated graph would be (x, y + 2).

This upward shift of 2 units can also be represented algebraically by adding 2 to the function f(x). So, if the original function was f(x), the shifted function would be f(x) + 2.

In summary, when we shift the graph of f(x) 2 units up, we move every point on the graph vertically upwards by 2 units or add 2 to the function.

Answer:

If the highest exponent of a polynomial function is even then the range of the function is never all real numbers.

Step-by-step explanation:

The value of x can be found by solving the system of equations x + y = 4 and y = 3. Evaluating z = x + y² with x = 1 and y = 2 yields a result of 7.

To find the value of x from the equations x + y = 4 and y = 3, we can substitute the value of y into the first equation. Substituting y = 3 into x + y = 4 gives x + 3 = 4. By subtracting 3 from both sides of the equation, we obtain x = 1. Therefore, the value of x is 1.

Next, we evaluate z = x + y² using the given values x = 1 and y = 2. Substituting these values into the expression, we have z = 1 + 2². Evaluating the squared term first, we get z = 1 + 4, which simplifies to z = 5. Hence, the value of z is 5 when x = 1 and y = 2.

Finally, the value of x is 1, and the value of z is 5 when x = 1 and y = 2.

If 1(1/4) pound of turkey is sold for $9, then the unit-price of the turkey is $7.20 per pound.

The "Unit-Price" is defined as the price of a single unit or item of a product, typically expressed in terms of a standard unit of measurement, such as price per pound, price per liter, or price per piece.

To find the unit price of turkey in the package, we need to divide the total cost of the package by the weight of the turkey in the package.

First, we need to convert 1(1/4) pounds to a decimal, which is 1.25 pounds.

Then, we can find the unit price by dividing the total-cost of $9 by the weight of the turkey in the package:

⇒ Unit price = (Total cost)/(Weight of turkey in package),

⇒ Unit price = $9/1.25 pounds,

⇒ Unit price = $7.20 per pound,

Therefore, the unit price of turkey in the package is $7.20 per pound.

Answer:

x = 47°

Step-by-step explanation:

In a kite the main diagonal AC bisects the opposite angles, then

∠ BAE = ∠ DAE = 43° , then ∠ A = 86°

Since AB and AD are congruent then Δ ABD is isosceles and the base angles are congruent, thus

x = \(\frac{180-86}{2}\) = \(\frac{94}{2}\) = 47°

Substituting u = x^(2/3x^6) in the integral ∫ (2x^3)(x^2/3x^6)^5 dx and arriving at the solution  3∫(x^3)(u^5) du.

To evaluate the integral ∫ (2x^3)(x^2/3x^6)^5 dx, we can simplify the expression by making the substitution u = x^(2/3x^6). This substitution allows us to transform the integral into a simpler form, making it easier to evaluate.

Let's make the substitution u = x^(2/3x^6). Taking the derivative of both sides with respect to x gives us du = (2/3x^6)(x^(-1/3)) dx. Simplifying this equation, we have du = (2/3)dx.

Now, we can rewrite the original integral in terms of u as follows:

∫ (2x^3)(x^(2/3x^6))^5 dx = ∫ (2x^3)(u^5) dx.

Using our substitution, we can also rewrite x^3dx as (3/2)du. Substituting these into the integral, we have:

∫ (2x^3)(x^(2/3x^6))^5 dx = ∫ (2x^3)(u^5) dx = 2∫(x^3)(u^5)dx = 2∫(x^3)(u^5)(3/2)du.

Simplifying further, we have:

∫ (2x^3)(x^(2/3x^6))^5 dx = 2(3/2) ∫ (x^3)(u^5) du = 3∫(x^3)(u^5) du.

Now, we can evaluate this integral with respect to u, which gives us a simpler expression to work with. Once we find the antiderivative of (x^3)(u^5) with respect to u, we can substitute u back in terms of x to obtain the final result.

Answer:

the median

Step-by-step explanation:

The median always means the middle or center

The choice function c satisfies finite nonemptiness and choice coherence, but there does not exist a utility function U , which does not contradict the Fundamental Theorem of Mindless Economics.

A. To show that the choice function c satisfies finite nonemptiness, we need to demonstrate that for each choice set Bn, c(Bn) is non-empty.

To show that the choice function c satisfies choice coherence, we need to demonstrate that for any two choice sets Bn and Bm, if Bn ⊆ Bm, then c(Bn) ⊆ c(Bm).

From the given information, we have B1 = {x, y}, B2 = {y, z}, and B3 = {x, z}. Let's consider the possible pairs of choice sets:

B1 and B2: B1 ⊆ B2 since {x, y} is a subset of {y, z}. In this case, c(B1) = {x} and c(B2) = {y}. We can observe that {x} ⊆ {y}, which satisfies the condition of choice coherence.

B1 and B3: B1 ⊆ B3 since {x, y} is a subset of {x, z}. In this case, c(B1) = {x} and c(B3) = {z}. We can observe that {x} ⊆ {z}, which satisfies the condition of choice coherence.

B2 and B3: B2 ⊈ B3 since {y, z} is not a subset of {x, z}. Therefore, the condition of choice coherence does not apply in this case.

Overall, the choice function c satisfies finite nonemptiness and choice coherence, except for the pair of choice sets B2 and B3.

B. To show that there does not exist a utility function U: {x, y, z} → R that can produce these choices via the usual formula c(Bn) = {x ∈ Bn : U(x) ≥ U(y) for all y ∈ Bn}, we need to demonstrate that such a utility function does not exist.

Let's consider the pairs of choice sets B1 and B2:

For B1 = {x, y}, we have c(B1) = {x}. To satisfy the usual formula, we would need a utility function U(x) ≥ U(y). However, since there is no order or preference provided for x, y, and z, we cannot assign numerical values to them in a way that U(x) ≥ U(y) holds.

Similarly, for B2 = {y, z}, we have c(B2) = {y}. Again, we cannot assign numerical values to y and z that satisfy U(y) ≥ U(z) since there is no preference or order specified.

Therefore, there does not exist a utility function U: {x, y, z} → R that can produce these choices via the usual formula.

C. The answers to parts (a) and (b) do not contradict the Fundamental Theorem of Mindless Economics because the choices made by the individual in this scenario do not adhere to the assumptions of utility maximization based on preferences.

The value of the function f(x) = 3x - 5 when x = 2 is f(2) = 1

A function is a mathematical equation that shows the relationship between two variables.

Given the function f(x) = 3x - 5, we desire to find f(2).

To find f(2), we substitute x = 2 into the equation. So, we have that

f(x) = 3x - 5. So substituting x = 2 into the equation, w ehave

f(2) = 3(2) - 5

f(2) = 6 - 5

Value of account after t years is
\(A = \boxed{190( 1.0178)^{4t}}\)

Percentage of growth per year

CAGR = \(\boxed{7.31\%}\)

Step-by-step explanation:

The generalized equation for the accrued value of an amount P(the principal) deposited at i% annual interest compounded n times a year for t years is

\(A = P\left(1 + \dfrac{r}{n}\right)^{nt}\)

where r = i/100, the interest rate expressed as a decimal

Given P = $190
i = 7.1% ==> r = 7.1/100 = 0.071

Since the interest is compounded quarterly and there are 4 quarters in a year, the interest is compounded 4 times a year so n = 4

\(A = 190 \left(1 + \dfrac{0.071}{4}\right)^{4t}\)

\(A = 190\left(1 + 0.01775\right)^{4t}}\\\\A = 190( 1.01775)^{4t}\)\

Rounding the annual growth rate to 4 decimal places gives

\(A = P(1.0178)^{4t}\)

In one year, the investment of $190 will grow to
\(A = 190(1.0178)^{4}\)

\(A = $203.89\)

Compound Annual Growth = = 203.89 - 190 = $13.89

Compound Annual Growth Rage(CAGR) = $13.89/$190 = 0.073105

As a percentage, CAGR Percent = 0.073105 x 100 = 7.3105% or rounded to nearest hundredth it would be 7.31%
