On the set of axes below, draw the graph of y=x²-4x-1
State the equation of the axis of symmetry.
Answers
Answer:
See below
Step-by-step explanation:
Best way to do this is to convert the equation to vertex form and that will tell you several points you can graph:
\(y=x^2-4x-1\\y+5=x^2-4x-1+5\\y+5=x^2-4x+4\\y+5=(x-2)^2\\y=(x-2)^2-5\)
Here, we can see that the vertex of the parabola is (2,-5) and that the axis of symmetry is x=2. You can also quickly get the y-intercept since plugging in x=0 gets you (0,-1). Finding a few more points should be pretty simple from here on out since your equation is more condensed.

The equation of the exponential function is\(4 * 3^{x}\).
What is exponential function?
An exponential function is of the form:
\(f(x) = a^{x}\)
here "a" is a constant called the base, and "x" is the variable. The base "a" is typically a positive real number, but it can also be a negative number or a complex number. The function is called exponential because the variable "x" appears in the exponent.
We can see that as "x" increases by 1, "y" is multiplied by a constant factor of 3. This suggests that the exponential function has a base of 3. To find the equation, we can use the general form of an exponential function:
\(y = a * b^{x}\)
where "a" is the initial value or y-intercept, and "b" is the base.
We can use the given values of (x,y) to form a system of equations:
\(a * 3^{0} = 4\)
\(a * 3^{1} = 12\)
\(a * 3^{2} = 36\)
\(a * 3^{3} = 108\)
Simplifying each equation, we get:
a = 4
3a = 12
9a = 36
27a = 108
Solving for "a", we get:
a = 4
Substituting this value of "a" into the equation, we get:
\(y = 4 * 3^{x}\)
So the equation of the exponential function represented by the table is y \(= 4 * 3^{x}.\)

divide y by x
I'm considering the line with the equation y equals x + 9 I need to find a line parallel to it which passes through -2 negative 4 and perpendicular which also passes through negative two negative 4
Answers
a) y = x - 2
b) y = -x -6
Explanation:\(\begin{gathered} \text{The equation:} \\ \text{y = x + 9} \\ \text{This equation is a staright line and has a slope} \end{gathered}\)a) parallel line that passes through (-2, -4)
For a line to be parallel to another line, the slope of both lines must be equal
y = x + 9
comparing with equation of line:
y = mx + b
mx = x
m = 1
Slope of first line = 1
slope of the 2nd line = 1
For the 2nd line, it passes through (-2, -4)
x = -2, y = -4
y = mx + b
-4 = 1(-2) + b
-4 = b - 2
-4 + 2 = b - 2 + 2
-2 = b + 0
b = -2
The equation parallel to y = x + 9 becomes:
y = x + (-2)
y = x - 2
b) For a line to be perpendicular to another line, the slope of one line will be thenegative reciprocal of the other line.
slope of 1st line = 1
reciprocal of the line = 1/1 = 1
negative reciprocal = -1
point (-2, -4)
y = mx + b
-4 = -1(-2) + b
-4 = 2 + b
-4 -2 = b
b = -6
The equation perpendicular to the line y = x + 9:
y = -1(x) + (-6)
y = -x -6

(Round to two decimal places.)
Answers
The investment's expected return is 5.95%.
Is the investment's expected return favorable for Gautney?The expected return of an investment is calculated by multiplying the probabilities of each possible return by their respective returns and summing them up. In this case, Gautney Enterprises has provided the probabilities and returns for the investment. By applying the formula, we find that the expected return is 5.95%.
To calculate the standard deviation, we need to determine the variance first. The variance is computed by taking the difference between each possible return and the expected return, squaring those differences, multiplying them by their respective probabilities, and summing them up. Once we have the variance, the standard deviation is simply the square root of the variance. The standard deviation measures the degree of risk associated with an investment.
In this scenario, the expected return of the investment is 5.95%, but we need to consider the standard deviation as well to assess the risk. If the standard deviation is high, it indicates a greater level of uncertainty and potential volatility in returns. A low standard deviation implies a more stable investment.
Without the specific values for each return and their respective probabilities, we cannot calculate the exact standard deviation. However, Gautney Enterprises should compare the calculated expected return and the associated standard deviation to their risk tolerance and investment objectives. If the expected return meets their desired level of return and the standard deviation aligns with their risk appetite, they may consider investing in this security.

Use guess and check to find an anti-derivative
F(x)
for
f(x)=sin(x)cos(x)
. Explain why you chose particular guesses, and how you checked them.
Answers
When finding an antiderivative using the method of guess and check, it is important to use a guess that is based on the original function and the rules of differentiation.
One approach to finding an antiderivative of a function is the method of guess and check. This involves making an educated guess for the antiderivative and then verifying it by taking the derivative of the guess and comparing it to the original function.
To find the antiderivative of f(x) = sin(x)cos(x), we can start with a guess based on the product rule for differentiation: d/dx (uv) = u * dv/dx + v * du/dx
Since f(x) = sin(x)cos(x), we can write: d/dx (sin(x)cos(x)) = cos^2(x) + sin^2(x) = 1
This suggests that the antiderivative of f(x) = sin(x)cos(x) might be: F(x) = sin(x)sin(x) + C, where C is an arbitrary constant of integration.
To check our guess, we need to take the derivative of F(x) and compare it to the original function f(x): d/dx (sin(x)sin(x) + C) = cos(x)sin(x)
If our guess is correct, the derivative of F(x) should equal f(x). However, in this case, our guess does not match the original function f(x), so we need to make another guess. A second guess could be:
F(x) = -cos(x)cos(x) + C
Taking the derivative: d/dx (-cos(x)cos(x) + C) = -sin(x)cos(x)
This time, the derivative of F(x) does match the original function f(x), so our guess is correct and the antiderivative of f(x) = sin(x)cos(x) is:
F(x) = -cos(x)cos(x) + C.
Thus, In conclusion, when finding an antiderivative using the method of guess and check, it is important to use a guess that is based on the original function and the rules of differentiation. By checking the derivative of the guess and comparing it to the original function, we can determine whether or not our guess is correct.

a rectangular plot of farmland will be bounded on one side by a river and on the other three sides by a​ single-strand electric fence. with m of wire at your​ disposal, what is the largest area you can​ enclose, and what are its​ dimensions?
Answers
To find the largest area you can enclose with a single-strand electric fence and m units of wire at your disposal, you need to optimize the dimensions of the rectangular plot.
Let's denote the length of the rectangular plot as L and the width as W. The perimeter of the plot can be calculated as P = L + 2W.
Since one side of the plot is already bounded by the river, we have L + W = m. Rearranging this equation, we get L = m - W.
To find the largest area, we need to maximize the function A = L * W. Substituting the value of L, we have A = (m - W) * W.
Expanding the equation, we have A = mW - W^2.
To find the maximum value of A, we take the derivative of A with respect to W and set it equal to zero: dA/dW = 0.
Differentiating, we get m - 2W = 0. Solving for W, we have W = m/2.
Substituting this value back into the equation for L, we have L = m/2.
Therefore, the dimensions of the largest area are L = m/2 and W = m/2.
To find the area, we substitute these values into the equation for A: A = (m/2) * (m/2) = m^2/4.
In conclusion, the largest area that can be enclosed is m^2/4, with dimensions L = m/2 and W = m/2.

Answers
The mass of salt in the tank at time t.
dS/dt = 10 - S/400
S(0) = 100 grams
The solution is S(t) = 4000 - 3900\(e^{\frac{-t}{400}}\)
A tank holds water V(0) = 4000 liters in which salt S(0) = 100 grams.
So dS/dt = S(in) - S(out)
S(in) = 1 × 10 = 10 gram/liters
S(out) = S/V × 10 = 10S/V gram/liters
V = V(0) + q(in) - q(out)
V = 4000 + 10t - 10t
V = 4000 liters
dS/dt = 10 - 10S/V
dS/dt = 10 - 10S/4000
dS/dt = 10 - S/400
Now given; S(0) = 100.
Here, p(t) = 1/400, q(t) = 10
\(\int p(t)dt = \int\frac{1}{400}dt\)\(\int p(t)dt = \frac{1}{400}t\)
\(\mu=e^{\int p(t)dt}\)
\(\mu=e^{\frac{t}{400}}\)
So, S(t) = \(\frac{\int\mu q(t)dt+C}{\mu}\)
S(t) = \(\frac{\int e^{\frac{t}{400}} \cdot10dt+C}{e^{\frac{t}{400}}}\)
S(t) = \(e^{\frac{-t}{400}} \left({\int e^{\frac{t}{400}} \cdot10dt+C}\right)\)
S(t) = \(e^{\frac{-t}{400}} \left({10\times\frac{e^{\frac{t}{400}}}{1/400} +C}\right)\)
S(t) = \(e^{\frac{-t}{400}} \left({4000\times{e^{\frac{t}{400}} +C}\right)\)
Now solving the bracket
S(t) = 4000 + \(e^{\frac{-t}{400}}\)C.....(1)
At S(0) = 100
100 = 4000 + \(e^{\frac{-0}{400}}\) C
100 = 4000 + \(e^{0}\) C
100 = 4000 + C
Subtract 4000 on both side, we get
C = -3900

Jen used 1/2 cup of cereal and 2/3 cup of nuts to make trail mix. Her mother asked if she used more cereal or more nuts in the mix. Which statement correctly compares the fractions?
Answers
1/2<2/3. 1/2= half of a whole and half of a whole is 1/2. 2/3 is over a half so it means that 2/3 is better then 1/2 since 1.5 is actually the half of 3. Jen should say that she used more nuts to make trail mix then using cup of cereal to make trail mix because 2/3 is greater then 1/2.

–6w + (–8.3) + 1.5+ (–7w)
Answers
The simplified form of the expression -6w + (–8.3) + 1.5+ (–7w) is -13w - 6.8.
What is the simplified form of the expression?Given the expression in the question;
-6w + (–8.3) + 1.5+ (–7w)
To simplify, first remove the parenthesis
Note that;
- × + = -- × - = ++ × + = +-6w + × - 8.3 + 1.5 + × - 7w
-6w - 8.3 + 1.5 - 7w
Next collect and add like terms
-6w - 7w - 8.3 + 1.5
Add -6w and -7w
-13w - 8.3 + 1.5
Add -8.3 and 1.5
-13w - 6.8
Therefore, -13w - 6.8 is the simplified form.

Which is most likely the correlation coefficient for the set of data shown?
–0.872
–0.191
0.191
0.872
Answers
The most likely correlation coefficient for the set of data shown is -0.872.
To determine the most likely correlation coefficient for the set of data, we need to examine the values provided: –0.872, –0.191, 0.191, and 0.872.
The correlation coefficient is a value between -1 and 1 that indicates the strength and direction of the linear relationship between two variables.
Since all the given values are positive (0.191 and 0.872) or negative (-0.191 and -0.872), we can conclude that the correlation coefficient is negative.
Out of the two negative values, -0.872 is closer to -1 than -0.191, so it is more likely the correlation coefficient for the given data set.
Therefore, the most likely correlation coefficient for the set of data shown is -0.872.
