Answer:

the correct answer is d

Step-by-step explanation:

The leading coefficient is negative, so the graph rises on the left and falls on the right.

Therefore as x approaches infinity, y will be approaching negative infinity.

The correct answer is x = 5

Triangle DBC is similar to triangle DBA.

So, by Similarity Theorem,

The correct answer is x = 5

Answer:

-6-(-1)

Step-by-step explanation:

Since all the boxes are negative, and there are 6 boxes, the first part of the equation is -6.  Then since the last box is being taken away, we are subtracting it.  The last box is still negative though so the last part is -1.  Since -6 subtracted by -1 is -6-(-1), the answer is:

-6-(-1)

Answer:

The mean of the batting averages is 0.341125.

Mean is used to summarize a set of data, frequently to help determine the overall significance of the data set.

To find the mean of the batting averages, we need to sum up all the batting averages and divide by the total number of players.

Batting averages: .373, .360, .321, .321, .320, .312, .311, .311

Sum of batting averages = .373 + .360 + .321 + .321 + .320 + .312 + .311 + .311

Sum of batting averages = 2.729

Now, we divide the sum by the total number of players, which is 8:

Mean = Sum of batting averages / Total number of players

Mean = 2.729 / 8

Calculating the mean:

Mean ≈ 0.341125

The mean of the batting averages is approximately 0.341125.

Step-by-step explanation:

Its the answer

Answer:

b is y=2x-1 and i dont know for a. im also stuck on it

Step-by-step explanation:

First, starting from the equation:

We should change every x for a y and every y for an x, so:

In the text, the first step was:

So, the first mistake was not to change the linear term 12x for 12y.

Another mistake was made from the following steps:

The expression inside the square root must be greater or equal to 0, then:

So, the second mistake was not to identify the domain of x correctly.

A third mistake is that the square root of y^2 is not y, it is |y|. So:

The average increase in first 2 days is 1.5 pennies/day.

Given is a tabular data about Daisy's piggy bank.

Answer:

About 28.27 inches² per slice

Step-by-step explanation:

   First, we will find the area of the pizza. Since it is a pizza, we will assume it is a circle and will use the formula for area of a circle.

   24-inch diameter / 2 = 12-inch radius

   A=πr²

   A=π(12)²

   A ≈ 452.39 inches²

   Now, since the pizza is cut into 16 slices, we will divide the total area by 16.

452.39 inches² / 16 ≈ 28.27 inches² per slice

Answer:

Shakeva will pay $44,086 for the purchase including all the fee.

Step-by-step explanation:

Given that:

Cost of car = $ 41.9K = 41.9*1000 = $41900

Sales tax = 5%

Sales tax = 0.05 * 41900 = $2095

Registration = $27

New title certificate = $19

State safety and emissions inspection = $45

Total amount = 41900 + 2095 + 27 + 19 + 45 = $44086

Hence,

Shakeva will pay $44,086 for the purchase including all the fee.

The number of cars needed for both repairs and needed new brakes, but not a new exhaust system will be 13 and 10, respectively.

Sets are groups of clearly specified components. The number of items in a finite set is denoted by a curly bracket.

At Auto Shop, 50 vehicles were investigated. 23 of the vehicles required new brakes (A), 34 required new fumes frameworks (B), and 6 vehicles required neither fix.

The number of cars that needs new brakes and new exhaust systems will be calculated as,

AUB = 50 - 6

AUB = 44

The number of cars needed for both repairs will be given as,

A∩B = A + B - AUB

A∩B = 23 + 34 - 44

A∩B = 13

The number of cars that needed new brakes, but not a new exhaust system will be given as,

⇒ 23 - 13

⇒ 10

The number of vehicles required for the two fixes and required new brakes, however not another exhaust framework will be 13 and 10, individually.

The slope of the line tangent to the graph of \(y = x^2 - 2x + 1\) when \(x = 1\) is 2.



1. Take the derivative of the given function: \(y' = 2x - 2\).

2. Substitute \(x = 1\) into the derivative: \(y' = 2(1) - 2 = 2\).



To find the slope of the tangent line, we need to differentiate the given function with respect to \(x\). The derivative of \(x^2\) is \(2x\), and the derivative of \(-2x\) is \(-2\). Therefore, the derivative of \(y = x^2 - 2x + 1\) is \(y' = 2x - 2\).

Next, we substitute \(x = 1\) into the derivative to find the slope at that point. By plugging in \(x = 1\) into the derivative, we get \(y' = 2(1) - 2 = 2\). Thus, the slope of the tangent line at \(x = 1\) is 2.

The value of α for which the system has a center as its critical point is α = -3.

The given system of equations is:

x₁' = αx₁ + 2x₂

x₂' = -3x₁ + 2x₂

To find the critical points, we set the derivatives equal to zero:

αx₁ + 2x₂ = 0

-3x₁ + 2x₂ = 0

From the first equation, we can solve for x1 in terms of x₂:

x₁ = (-2x₂) / α

Substituting this expression into the second equation:

-3((-2x₂) / α) + 2x₂ = 0

(6x₂ / α) + 2x₂ = 0

Multiplying through by α:

6x₂ + 2αx₂ = 0

Factoring out x₂:

6 + 2α) x₂ = 0

For x₂ to be nonzero, the term (6 + 2α) must be zero:

6 + 2α = 0

Solving for α:

2α = -6

The value of expected time ex(b)=1 day approximately if b is the number of days a busy student delays Laundry.

The basic anticipated value formula is (P(x) * n): the probability of an occurrence multiplied by the number of times the event occurs.

The expected value (also known as the expectation, expectancy, mathematical expectation, mean, average, or first moment) is a generalization of the weighted average in probability theory. The anticipated value is the arithmetic mean of a large number of independently chosen random variable outcomes.

The modified Reynolds analogy, also known as the Chilton-Colburn analogy, is expressed mathematically as Nu = f * Re^m * Pr^n. It relates the convective heat transfer coefficient (h) to the skin friction coefficient (Cf) in fluid flow. This equation is widely used in heat transfer analysis and design applications involving forced convection.

The modified Reynolds analogy is a useful tool in heat transfer analysis, especially for situations involving forced convection. It provides a correlation between the heat transfer and fluid flow characteristics. The Nusselt number (Nu) represents the ratio of convective heat transfer to conductive heat transfer, while the Reynolds number (Re) characterizes the flow regime. The Prandtl number (Pr) relates the momentum diffusivity to the thermal diffusivity of the fluid.

The equation incorporates the friction factor (f) to account for the energy dissipation due to fluid flow. The values of the constants m and n depend on the flow conditions and geometry, and they are determined experimentally or by empirical correlations. The modified Reynolds analogy is widely used in engineering calculations and design of heat exchangers, cooling systems, and other applications involving heat transfer in fluid flow.

Answer:

The expressions are equal.

Step-by-step explanation:

Notice that \(a^{-b}=\frac{1}{a^b}\) for all (real) \(a,b\). So \(4^{-2}=\frac{1}{4^2} = \frac{1}{16}\) and \(2^{-4} = \frac{1}{2^4} = \frac{1}{16}\). Therefore, the expressions are equal.

However, I can explain the process of simplifying the given functions using the Karnaugh Map (K-Map) method and provide you with the minimized SOP and POS forms.

For the year in which they earned $176,500, the partners will receive $52,950, $35,300, and $88,250 respectively.

Here let the partners be A, B, and C.

According to the question, A: B: C = 3: 2: 5

This implies that if the profits are divided into

3 + 2 + 5 = 10 equal parts, 3 of those parts will go to A, 2 of those parts will go to B and 5 of those parts will go to C.

Here the profits for the year are $176,500.

Now dividing them into 10 equal parts will give us the value of each part to be

$176, 500/10 = $17,650

Hence A will receive $17,650 X 3 = $52,950

B will receive $17,650 X 2 = $35,300

C will receive $17,650 X 5 = $88,250

In Mathematics, the translation of a geometric figure to the right simply means adding a digit to the value on the x-axis of the pre-image of a function while a geometric figure that is translated downward simply means subtracting a digit from the value on the y-axis of the pre-image or parent function.

Mathematically, a horizontal translation to the right is modeled by this function g(x) = f(x + N) while a vertical translation to the negative y-direction (downward) is modeled by this function g(x) = f(x) + N.
