Answer: $2.21
Step-by-step explanation:
To calculate the cost per pound of mushrooms, we need to use the yield factor given in the question. The yield factor tells us the percentage of the total weight of the mushrooms that can be used for cooking or sale. Here, the yield factor is 90%, which means that 90% of the weight of the mushrooms can be used. Let's begin with the calculation:
First, we need to find out how much of the weight of the mushrooms is usable: 90% of 15 pounds = 0.9 x 15 = 13.5 pounds
Now, we can find out the cost per pound of the mushrooms:
Cost per pound = Total cost / Total usable weight
Total cost = $29.85
Total usable weight = 13.5 pounds
Therefore, the cost per pound of mushrooms = $29.85 / 13.5 pounds ≈ $2.21 per pound
Therefore, the cost per pound of mushrooms is $2.21 per pound.

Find the domain of the function y = 3 tan(2/3x
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.
What is the domain of the trigonometric function?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.
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.

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=(n30s302)+(n60s602)
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.

Determine the equation of the circle graphed below
Answer:
(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
c ~ 5.1
Plug the radius we solved for in for r:
(x-2)^2 + (y+3)^2 = 5.1^2

The algebric expression -1/4 + 3/5 is equal to 7/20 when simplified.
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.

Option D. The deg (f ^ 3) = 3m
How to Interpret the degree of Polynomial functions?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.
Option B: deg(f * g) <= m + n
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.
D. The deg(f ^ 3) = 3m

*If you were to run a double batch through mixer 1 (using 2,000 LBS of flour) how many LBS of water would you need?
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.

To simplify the expression 14√27 - √3, we can simplify the radicals and then perform the subtraction:
First, let's simplify the radicals:
√27 = √(9 × 3) = √9 × √3 = 3√3
Now we can rewrite the expression:
14√27 - √3 = 14(3√3) - √3
Next, distribute the 14:
14(3√3) - √3 = 42√3 - √3

Kirsten got paid $432.50 for her work this month. She worked for 35 hours but broke a coffee mug so had to take $5 out of her pay. Write an equation, define your variable and solve. How much does she make an hour?
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

Answer:
Yes, the triangle are similar.
Step-by-step explanation:
To prove that 2 triangle are similar you only need to prove that 2 corresponding angles are equal.
The sum of the interior angles add to 180.
< m on the left measures 30 degrees.
80 - 90 - 60 = 30
> t on the right measures 60 degrees.
180 - 90 - 30 = 60
If two corresponding angles of two triangles are equal that forces the third pair to be congruent, since the total of the angles must add up to 180.
Although we are not given the corresponding sides, there are proportional because the angles are equal.

Based on the table, what is the equation of the linear relationship in slope-intercept form?
y = 2x − 8
y = 2x + 8
y = −2x + 4
y = −2x − 4
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.

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 2nd term of an GP is 50more than the pth term and (n+1)term is 56 find the first term
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'.

100 Points! Geometry question. Photo attached. Only looking for an answer to B. Please show as much work as possible. Thank you!
Answer: Read the solution
Step-by-step explanation:
A. For diagram A, triangles ANC and BDE are similar. Thus, we can use similarity ratios to find the length of AC. (x+1)/12 = (x+5)/15. 15x+15=12x+60. Thus 3x=45, and x=15. Since we need to find AC, AC = 15+1 = 16.
B. For diagram B, triangles SRT and VUT are similar. Again, using similarity ratios, (4x-1)/14=(x+2)/6 or 14x+28=24x-6. 10x=34, x=3.4.

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.

P=x-2 ÷ x+1 for what value of x is P undefined
Answer:
x = - 1
Step-by-step explanation:
P = [tex]\frac{x-2}{x+1}[/tex]
the denominator of the rational function cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that x cannot be.
x + 1 = 0 ( subtract 1 from both sides )
x = - 1
P is undefined when x = - 1

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.

Help with math problem please
The interval to the solution is (a) the interval from -7 to 6
How to determine the interval to the solutionFrom the question, we have the following parameters that can be used in our computation:
log(x + 9) + log(x - 9) = 0.47712
Apply the rule of logarithm
So, we have
log(x² - 9) = 0.47712
Take the exponent of both sides
x² - 9 = [tex]10^{0.47712[/tex]
So, we have
x² = 9 + [tex]10^{0.47712[/tex]
Evaluate
x² ≈ 12
Take the square root of both sides
x ≈ ±3.46
This value is between the interval -7 to 6
