End behavior of a function f defines the behavior of the function's graph at the "ends" of the x-axis. In other words, the end behavior of a function explains the graph's trend when we look to the right end of the x-axis (as x approaches +∞ ) and to the left end of the x-axis (as x approaches −∞ ).

A function is an equation with just one solution for y for every x. A function produces exactly one output for each input of a certain type. Instead of y, it is usual to call a function f(x) or g(x). f(2) indicates that we should discover our function's value when x equals 2. Example. A function is a type of rule that produces one output for one input. Alex Federspiel provided the image. y=x2 is an example of this. If you enter anything for x, you will only get one output for y. Because x represents the input value, we may say that y is a function of x.

Here,

Answer:

\(\dfrac{1}{729}\)

Step-by-step explanation:

\(\left(\dfrac{}{}(-3)^2\dfrac{}{}\right)^{-3}\)

First, we should evaluate inside the large parentheses:

\((-3)^2 = (-3)\cdot (-3) = 9\)

We know that a number to a positive exponent is equal to the base number multiplied by itself as many times as the exponent. For example,

\(4^3 = 4 \, \cdot\, 4\, \cdot \,4\)

       ↑1 ↑2 ↑3 times because the exponent is 3

Next, we can put the value 9 into where \((-3)^2\) was originally:

\((9)^{-3}\)

We know that a number to a negative power is equal to 1 divided by that number to the absolute value of that negative power. For example,

\(3^{-2} = \dfrac{1}{3^2} = \dfrac{1}{3\cdot 3} = \dfrac{1}{9}\)

Finally, we can apply this principle to the \(9^{-3}\):

\(9^{-3} = \dfrac{1}{9^3} = \boxed{\dfrac{1}{729}}\)

The function \(f(x) = 4x^3 - 4\) is a polynomial function. It takes an input value x and returns an output value f(x) based on the expression \(4x^3 - 4.\)So the value of f(-1/2) is -4.5.

When we evaluate f(-1/2), we substitute -1/2 for x in the expression for f(x). This gives us:

\(f(-1/2) = 4(-1/2)^3 - 4\)

The expression inside the parentheses, \((-1/2)^3,\\\) is the cube of -1/2. To simplify this expression, we need to first raise -1/2 to the power of 3:

\((-1/2)^3 = (-1/2) * (-1/2) * (-1/2) = -1/8\)

Next, we substitute this value back into the expression for f(-1/2):

f(-1/2) = 4(-1/8) - 4

Now we can simplify the expression by multiplying 4 and -1/8:

f(-1/2) = -1/2 - 4

Finally, we subtract 4 from -1/2 to get the final answer:

f(-1/2) = -4.5

So the value of f(-1/2) is -4.5.

The equation of tangent line to the curve y = ln(x^2 - 4x + 1) is y = 4x -16.

According to the given question.

We have a curve y = ln(x^2 - 4x + 1)

Let the equation of tangent line to the curve y = ln(x^2 - 4x + 1) be

y = mx + b

Where, m is the slope of the curve.

So, the slope of the curve m, y = ln(x^2 - 4x + 1) at x = 4 is given by

m = dy/dx

⇒ m = d(ln(x^2 - 4x + 1))/dx

\(\implies m = \frac{1}{(x^{2} -4x+1)}\frac{d}{dx}(x^{2} -4x+1)\)

\(\implies m = \frac{1}{(x^{2} -4x+1)} (2x -4)\)

\(\implies m = \frac{1}{(16-16+1)} (8-4)\)       (at x = 4)

⇒ m = 1(4)

⇒ m = 4

Substitute the value of m in y = mx + b

⇒ y = 4x + b

Since, the above tangent line is passing through (4, 0). So, the point (4, 0) must satisfy y = 4x + b.

⇒ 0 = 4(4) + b

⇒ b = -16

Therefore, the equation of tangent line to the curve y = ln(x^2 - 4x + 1) is given by

y = mx + b

⇒ y = 4x -16        (by substituting the vale of m and b in y = mx+b)

Hence, the equation of tangent line to the curve y = ln(x^2 - 4x + 1) is y = 4x -16.

So, Pythagoras theorem can be used,

Hypotenuse ² = base ² + altitude ²

AB²=AC²+BC²

11²=AC²+4²

11²-4²=AC²

121-16=AC²

Root 105=AC

AC=10.2 cm

The length of AC is 10.25 cm

If ΔABC is a right angle triangle, then

AB² = BC²+AC²

where AB = Hypotenuse, BC & AC are adjacent sides of the right angle

Given, hypotenuse = AB = 11 cm

One of adjacent sides = BC = 4 cm

We have to find the length of AC.

Using pythagorean theorem,

AB² = BC²+AC²

⇒ AC² = AB² - BC²

⇒ AC² = 11²-4²

⇒ AC² = 121-16

⇒ AC = √105

⇒ AC = 10.25

Answer:

\(\displaystyle{y-1=5(x+6)}\)

Step-by-step explanation:

A point-slope form is written in the equation of  \(\displaystyle{y-y_1=m(x-x_1)}\). Where \(\displaystyle{(x_1,y_1)}\) is a coordinate point and \(\displaystyle{m}\) is slope.

The definition of parallel is to both lines have same slope. The given line equation has slope of 5. Therefore, we can write the equation in point-slope form as:

\(\displaystyle{y-y_1=5(x-x_1)}\)

Next, we are also given the point p(-6,1). Substitute \(\displaystyle{x_1}\) = -6 and \(\displaystyle{y_1}\) = 1 in:

\(\displaystyle{y-1=5[x-(-6)]}\\\\\displaystyle{y-1=5(x+6)}\)

Hence, the line equation that’s parallel to y = 5x - 4 and passes through a point (-6,1) is y - 1 = 5(x + 6)

Answer:

y - 1 = 5 ( x + 6 )

Step-by-step explanation:

       Here,

          m ⇒ slope

    y = 5x - 4 ← equation of the old line

         Now it is clear to us that,

         m ⇒ slope of the line ⇒ 5

         c  ⇒ y-intercept ⇒ -4

                 That is, m = 5

                   y - y₁ = m ( x - x₁ ).

        m = slope

           ( -6 , 1 ) ⇔ ( x₁ , y₁ )

        Let us solve this now

         y - y₁ = m ( x - x₁ )

         y - 1 = 5 ( x - ( -6) )

         y - 1 = 5 ( x + 6 )

                y - 1 = 5 ( x + 6 )

While we can estimate the chance that the sum of the draws will be positive using the binomial distribution, the specific probability would depend on the distribution of the positive and negative numbers on the tickets.

Based on the information given, we can estimate the chance that the sum of the draws will be positive.

Since the draws are made with replacement, each draw is independent of the others. This means that the probability of drawing a positive number on any given draw is 4/10 (since there are four positive tickets out of ten).

The sum of the draws will be positive if the number of positive draws is greater than the number of negative draws. To estimate the chance of this happening, we can use the binomial distribution.

Let X be the number of positive draws in 1000 draws. X follows a binomial distribution with parameters n = 1000 (number of draws) and p = 4/10 (probability of success on a single draw).

We want to find P(X > 500), which represents the probability of having more than 500 positive draws out of 1000 draws.

Using statistical software or tables, we can calculate this probability. However, without specific information about the distribution of the positive and negative numbers on the tickets (e.g., if they are uniformly distributed), we cannot provide an exact estimate.

The recommended estimated regression equation is Y = βo + β1X1 + β2X2, with any coefficients for the independent variables that were removed set to 0.

The recommended estimated regression equation can be determined by removing all independent variables that are not significant at the 0.01 level of significance. The formula for the estimated regression equation is Y = βo + β1X1 + β2X2 + β3X3 + β4X4, where Y is the dependent variable, X1, X2, X3 and X4 are the independent variables, and β1, β2, β3 and β4 are the regression coefficients.

Using the coefficients from the original regression equation, we can determine which independent variables need to be removed by looking for any that have a p-value greater than the 0.01 level of significance. In this case, we will set the coefficients for the independent variables that need to be removed to 0. The recommended estimated regression equation is Y = βo + β1X1 + β2X2 + 0X3 + 0X4.

Therefore, the recommended estimated regression equation is Y = βo + β1X1 + β2X2, with any coefficients for the independent variables that were removed set to 0.
