Which value of c is in the domain of f(x)

Answer:

Kirsten makes $12.50 per hour

Step-by-step explanation:

The total is $432.50

$5 is taken out of her paycheck, so that will be negative.

35 hours is the time she spent working.

The unknown variable we are looking for is the amount she makes in one hour.

Setting up the equation, we get:

$432.50 = $35x - $5

where x is the amount she makes every hour

Solve for x:

$437.50=$35x

$437.50 / $35 = x

Therefore, x = $12.50

The equation of the linear relationship in slope-intercept form is y = 2x - 8. Option A is the correct answer.

To determine the equation of the linear relationship in slope-intercept form based on the table, we need to find the slope and y-intercept.

By observing the table, we can calculate the slope by selecting any two points. Let's choose the points (0, -8) and (4, 0).

Slope (m) = (change in y) / (change in x)

= (0 - (-8)) / (4 - 0)

= 8 / 4

= 2

Now that we have the slope, we can find the y-intercept by substituting the values of one point and the slope into the equation y = mx + b and solving for b.

Using the point (0, -8):

-8 = 2(0) + b

b = -8

Therefore, the equation of the linear relationship in slope-intercept form is: y = 2x - 8. Option A is the correct answer.

Therefore, for a double batch of 2,000 lbs of flour in mixer 1, you would need 8,000 lbs of water.

To determine the amount of water needed for a double batch of 2,000 pounds (lbs) of flour in mixer 1, we need to consider the ratio of water to flour.

Typically, when making a batch, there is a specific ratio of water to flour. Let's assume the ratio is 1:2, meaning for every 1 pound of flour, we need 2 pounds of water.

For a double batch, we need to multiply the amount of flour by 2:

2,000 lbs of flour × 2 = 4,000 lbs of flour.

Using the ratio, we multiply the amount of flour by the ratio:

4,000 lbs of flour × 2 lbs of water per 1 lb of flour = 8,000 lbs of water.

Therefore, an appropriate confidence interval for μ30−μ60μ30​−μ60​ (the difference in mean body temperature) would be −0.796−0.796 to −0.404−0.404 (rounded to the appropriate decimal places).

To estimate the difference in the mean body temperature after exercising for 30 minutes versus 60 minutes, we can construct a confidence interval. Since the conditions for inference have been assumed to be met, we can proceed with the following steps:

   Calculate the difference in sample means: xˉ30−xˉ60=38.3−38.9=−0.6xˉ30​−xˉ60​=38.3−38.9=−0.6.

   Determine the standard error of the difference, which is given by the formula:

   SE=(s302n30)+(s602n60)SE=(n30​s302​​)+(n60​s602​​)

Substituting the values, we have:

SE=(0.27218)+(0.29224)≈0.100SE=(180.272​)+(240.292​)  ​≈0.100.

   Choose an appropriate confidence level. Let's say we want a 95% confidence interval.

   Using the standard error, calculate the margin of error, which is given by multiplying the critical value (corresponding to the chosen confidence level) by the standard error. For a 95% confidence level, the critical value is approximately 1.96.

   Margin of Error = 1.96 * 0.100 ≈ 0.196.

   Construct the confidence interval by subtracting and adding the margin of error to the difference in sample means:

   −0.6−0.196−0.6−0.196 to −0.6+0.196−0.6+0.196.

The value of dy/dt  at x= 1 if y = [tex]3x^2[/tex] - 3 and dx/dt = 3 is 18.

To find dy/dt at x = 1, we need to differentiate the given equation y = [tex]3x^2[/tex] - 3 with respect to t and then substitute x = 1 and dx/dt = 3.

Let's begin by differentiating y = [tex]3x^2[/tex]- 3 with respect to t using the chain rule. Since y is a function of x and x is a function of t, we have:

dy/dt = (dy/dx) * (dx/dt)

Given dx/dt = 3, we can rewrite the equation as:

dy/dt = [tex](dy/dx) * 3[/tex]

Now, let's find the derivative of y = [tex]3x^2 - 3[/tex] with respect to x:

dy/dx = d/dx[tex](3x^2 - 3)[/tex]

= 6x

Substituting this back into the equation for dy/dt, we get:

dy/dt = [tex](6x) * 3[/tex]

= 18x

Finally, we can evaluate dy/dt at x = 1:

dy/dt at x = 1 = 18(1)

= 18

Therefore, the value of dy/dt at x = 1 is 18.

It's important to note that the value of dx/dt = 3 was given, and we used it to find dy/dt using the chain rule and the derivative of the equation with respect to x.

b. The vertical shift of the graph of G(x) compared to the graph of F(x) is an upward shift of 1 unit, while there is no horizontal shift between the two graphs.

In the functions G(x) = 2^(-x) and F(x) = 2^x:

Vertical Shift:

The vertical shift refers to the movement of a graph up or down along the y-axis. In this case, comparing G(x) = 2^(-x) to F(x) = 2^x, there is a vertical shift present.

The graph of F(x) = 2^x has its vertex (the lowest point of the graph) at the point (0, 1) on the coordinate plane.

The graph of G(x) = 2^(-x) is obtained by reflecting the graph of F(x) about the x-axis. This reflection results in a vertical shift of the graph. The graph of G(x) will have its vertex (the highest point of the graph) at the point (0, 1).

Therefore, the vertical shift of the graph of G(x) compared to the graph of F(x) is an upward shift of 1 unit.

Horizontal Shift:

The horizontal shift refers to the movement of a graph left or right along the x-axis. In this case, comparing G(x) = 2^(-x) to F(x) = 2^x, there is no horizontal shift present.

Both G(x) = 2^(-x) and F(x) = 2^x have their graphs centered at the y-axis, passing through the point (0, 1). Therefore, there is no horizontal shift between the two functions.

The domain of the function y = 3 tan(2/3x) is all real numbers except for x = (3n + ³/₂)π., where n is an integer.

The function is given as: y = 3 tan(2/3x)

The function above is defined for all values of x except where the tangent function is undefined. The tangent function is undefined at angles where the cosine is zero. In this case, the cosine is zero when 2/3x is equal to an odd multiple of π/2.

So we set (2/3)x equal to (2n + 1)π/2, where n is an integer:

(2/3)x = (2n + 1)π/2.

To solve for x, we multiply both sides by 3/2:

x = (3/2)(2n + 1)π/2.

x = (3n + ³/₂)π.

Therefore, the function is undefined when x is equal to (3n + 3/2)π, where n is an integer.

(x-2)^2 + (y+3)^2 = 5.1^2

Step-by-step explanation:

The equation of a circle is (x-h)^2 + (y-k)^2 = r^2, where h and k are the x and y values of the center of the circle respectively and r stands for the radius.

The center is given to us, at (2, -3) so we can plug that in:

(x-(2))^2 + (y- (-3))^2 = r^2

Simplify:

(x-2)^2 + (y+3)^2 = r^2

We can also solve for the radius by getting another point given to us: (3,2).

Using the pythagorean theorem, we can find how far the two points are away from each other:

a^2 + b^2 = c^2

1^2 + 5^2 = c^2
1 + 25 = c^2

26 = c^2

Answer:

To determine the first term of the geometric progression, let's assume it is 'a'. From the given information, we know that:

Second Term = a + 50

(n + 1)th Term = a + 56

We also have the formula for the nth term of a geometric sequence:

nth term = a * r^(n-1)

where 'r' is the common ratio between consecutive terms. Since the difference between consecutive terms remains constant, i.e., 50 for the second term and 56 for the (n + 1)th term, we can set up the equation:

a + 50 = a * r^1

a + 56 = a * r^2

Solve the equations simultaneously:

a + 50 = a * r^1 => a - 50/r = 0

a + 56 = a * r^2 => a - 56/r = 0

Adding the two equations, we get:

2a - (50/r + 56/r) = 0

2a - (50 + 56)/r = 0

Simplifying the equation further, we obtain:

2a - (106/r) = 0

Now, solve for 'a':

2a - (106/r) = 0

2a = (106/r)

=> 2a = 106/r

The value of 'a' depends on the value of 'r', so we cannot determine its exact value without knowing 'r'. However, once we know 'r', we can calculate the value of 'a'.

The solution to the system of linear equations is (x, y, z) = (64/11, 37/11, 9/11). The system has exactly one solution.

Let's solve the system of linear equations correctly.

The given system of linear equations is:

x = y + 3z = 6

x - 2y = 5

2x - 2y + 5z = 9

To determine the number of solutions, we can analyze the system using the method of elimination or substitution. Let's use the method of elimination:

From equation 1, we have:

x = y + 3z

Substituting this value of x in equation 2:

(y + 3z) - 2y = 5

y + 3z - 2y = 5

-z + 3z = 5 - y

2z = 5 - y

Now, let's substitute the value of x in equation 3:

2(y + 3z) - 2y + 5z = 9

2y + 6z - 2y + 5z = 9

11z = 9

Simplifying the equation, we find:

z = 9/11

Now, substituting this value of z back into the equation 2z = 5 - y, we get:

2(9/11) = 5 - y

18/11 = 5 - y

18/11 - 5 = -y

18/11 - 55/11 = -y

-37/11 = -y

y = 37/11

Finally, we can substitute the values of y and z into equation 1 to find the value of x:

x = y + 3z

x = 37/11 + 3(9/11)

x = 37/11 + 27/11

x = 64/11

Therefore, the solution to the system of linear equations is (x, y, z) = (64/11, 37/11, 9/11).

The system has exactly one solution.

Option D. The deg (f ^ 3) = 3m​

For polynomial functions f(x) and g(x), if deg(f) = m * deg(g) = n, then we have the following:

Option A: deg(f + g) = max(m, n)

This is true because we know that the degree of the sum of two polynomials is the maximum of their individual degrees.

This is true because we know that the degree of the product of two polynomials is at most the sum of their individual degrees.

Option C: If g is a factor of f, then deg(f) <= m

This is true because If g is a factor of f, it means that f can be divided by g without leaving a remainder. In this case, the degree of f is less than or equal to the degree of g.

To solve the expression -1/4 + 3/5, we need to find a common denominator for the fractions and then perform the addition.

The common denominator for 4 and 5 is 20. We can rewrite the fractions with this denominator:

-1/4 = -5/20

3/5 = 12/20

Now that the fractions have the same denominator, we can add them:

-5/20 + 12/20 = (-5 + 12)/20 = 7/20

Therefore, -1/4 + 3/5 is equal to 7/20.

To further simplify the fraction, we can check if there is a common factor between the numerator and denominator. In this case, 7 and 20 have no common factors other than 1, so the fraction is already in its simplest form.

Thus, the final answer is 7/20.
