The sum of torques (∑τ) about the elbow is Fbiceps × dbiceps - (Mforearm + Mball) × felbow, assuming only biceps force and weight act.
The force (τ) about the elbow can be communicated as the result of the power (F) applied and the opposite distance (d) from the turn highlight the line of activity of the power, i.e., τ = F × d. The amount of forces (∑τ) about the elbow is the amount of forces because of the relative multitude of powers following up on the lower arm.Accepting that the main powers following up on the lower arm are the biceps force (Fbiceps) and the heaviness of the lower arm and ball (Mforearm + Mball) acting at the focal point of mass of the lower arm and ball framework, we can communicate ∑τ about the elbow as:
∑τ = Fbiceps × dbiceps - (Mforearm + Mball) × felbow
where dbiceps is the opposite separation from the turn highlight the line of activity of the biceps force, felbow is the opposite separation from the turn highlight the focal point of mass of the lower arm and ball framework, and g is the speed increase because of gravity. Note that we accept the course of the biceps force is opposite to the lower arm and ball framework.In this way, the articulation for ∑τ about the elbow is ∑τ = Fbiceps × dbiceps - (Mforearm + Mball) × felbow.

Use logarithmic differentiation to find the derivative of the function. y=(ln(x+4)) x
the derivative of the function y = (ln(x + 4))x using logarithmic differentiation is given by y' = (ln(x + 4))x * [ln(ln(x + 4)) + (1/ln(x + 4)) * (1/(x + 4))].
To find the derivative of the function y = (ln(x + 4))x using logarithmic differentiation, we can follow these steps:
Step 1: Take the natural logarithm of both sides of the equation:
ln(y) = ln((ln(x + 4))x)
Step 2: Use the logarithmic property ln(a^b) = b ln(a) to simplify the right-hand side of the equation:
ln(y) = x ln(ln(x + 4))
Step 3: Differentiate both sides of the equation implicitly with respect to x:
(1/y) * y' = ln(ln(x + 4)) + x * (1/ln(x + 4)) * (1/(x + 4))
Step 4: Simplify the expression on the right-hand side:
y' = y * [ln(ln(x + 4)) + (1/ln(x + 4)) * (1/(x + 4))]
Step 5: Substitute the original expression of y = (ln(x + 4))x back into the equation:
y' = (ln(x + 4))x * [ln(ln(x + 4)) + (1/ln(x + 4)) * (1/(x + 4))]
Therefore, the derivative of the function y = (ln(x + 4))x using logarithmic differentiation is given by y' = (ln(x + 4))x * [ln(ln(x + 4)) + (1/ln(x + 4)) * (1/(x + 4))].

Which facts could be applied to simplify this expression? Select three options.
(Negative 5 x minus 3 y) minus (negative x minus 3 z)
To subtract like terms, subtract the coefficients, not the variables.
Like terms are terms that contain the same variable, raised to the same power.
The simplified expression is Negative 6 x minus 3 y + 3 z.
The simplified expression is Negative 4 x minus 3 y + 3 z.
Negative (negative x) is equivalent to Negative x, so Negative 5 x minus x = negative 6 x
Answer:
Negative 4 x minus 3 y + 3 z.
Step-by-step explanation:
We need to simplify the given expression : (-5x-3y)-(-x-3z)
Here, x,y and z are variables.
Combining like terms, we get :
(-5x-3y)-(-x-3z) = (-5x-3y)+x+3z
= (-5x+x)-3y+3z
= -4x-3y+3z
Hence, the equivalent expression is -4x-3y+3z. Hence, the correct option is (b) "The simplified expression is Negative 4 x minus 3 y + 3 z".

The area of a rectangle can be expressed by 2x2 – 7x – 4. If the rectangle has an
area of 45, find the positive value for x.
Answer:
7
Step-by-step explanation:
2x^2 - 7x - 4 = 45
2x^2 - 7x - 49 = 0 : subtract 45 from both sides
Quadratic formula:
x = (7 ± sqrt(7^2 - 4*2*-49) ) / 4
x = (7 ± sqrt(49 - -392)) / 4
x = (7 ± sqrt(441)) / 4
x = (7 ± 21) / 4
x = (7 + 21) / 4 OR x = (7 - 21) / 4
x = 28 / 4 OR x = -14 / 4
x = 7 as it is the only positive answer
.3y + 3 (1 - y - y = 6
Answer:
sorry it's too long
Step-by-step explanation:
Simplifying
3y + 3(1 + -1y) + -1y = 6
3y + (1 * 3 + -1y * 3) + -1y = 6
3y + (3 + -3y) + -1y = 6
Reorder the terms:
3 + 3y + -3y + -1y = 6
Combine like terms: 3y + -3y = 0
3 + 0 + -1y = 6
3 + -1y = 6
Solving
3 + -1y = 6
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + -1y = 6 + -3
Combine like terms: 3 + -3 = 0
0 + -1y = 6 + -3
-1y = 6 + -3
Combine like terms: 6 + -3 = 3
-1y = 3
Divide each side by '-1'.
y = -3
Simplifying
y = -3

2
hours to spend at the gym, how many times can she go through her workout cycle?
Write your answer as a whole number, fraction, or mixed number. Simplify any fractions.
Answer:
3 times.
Step-by-step explanation:
She has 1 1/2 hour to spend in the gym.
1 hr = 60 minutes.
1/2 of an hour= 1/2 * 60= 30 minutes.
In total, she spends 90 minutes in the gym.
If 1/3 of an hour is meant in running, it translates into: 1/3 * 60 = 20 minutes.
If 1/6 of an hour is spent in weight-lifting, it translates into: 1/6 * 60 = 10 minutes.
In total, she spends, 20 minutes + 10 minutes = 30 minutes for both activities.
To obtain the number of times she would perform both activities, we divide the total amount of time spent in the gym by the amount of time spent for both activities.
90 minutes/30 minutes= 3 times for each cycle.

Maria is bringing her sick dog Pedro in for a series of appointments at the veterinary clinic. Her total cost over the course of treatment will be $150 for tests and medicine plus $30 per appointment, a. The clinic offers her a 15% discount on total cost. What is her final cost if she visits the vet 3 times.
In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
tests and medicine = $150
appointment = $30
discount = 15% = 0.15
visits = 3
final cost = ?
Step 02:
final cost:
final cost = (150 + 30*3) - (150 + 30*3)*0.15
= 240 - 36
= $204
The answer is:
The final cost is $204

The value of x is equal to 15°
How to determine the value of x?In Mathematics and Geometry, the sum of the exterior angles of both a regular and irregular polygon is always equal to 360 degrees.
Note: The given geometric figure (regular polygon) represents a pentagon and it has 5 sides.
By substituting the given parameters, we have the following:
3x + 4x + 8 + 5x + 5 + 6x - 1 + 5x + 3 = 360°.
3x + 4x + 5x + 6x + 5x + 8 + 5 - 1 + 3 = 360°.
23x + 15 = 360°.
23x = 360 - 15
23x = 345
x = 345/23
x = 15°.

An equation of the best-fit line for the data is y = -0.27x + 10.28.
How to find an equation of the line of best fit for the data?In order to determine a linear equation for the line of best fit (trend line) that models the data points contained in the table, we would have to use a graphing calculator (scatter plot).
In this scenario, the drops of fertilizer would be plotted on the x-axis of the scatter plot while the height (in inches) would be plotted on the y-axis of the scatter plot.
From the scatter plot (see attachment) which models the relationship between the drops of fertilizer and height (in inches), a linear equation for the line of best fit and correlation coefficient are as follows:

3) Find the length of the final scarf
A full scarf has a length of 150cm
We must use the fragment that is 1/2 this size
150 ÷ 2 = 75
We must use the second fragment which is 3/4 150cm
Divide the scarf into 4 pieces
150 ÷ 4 = 37.5
We need 3 1/4 fragments to = 3/4
37.5 x 3 = 112.5
The final fragment is 1/3 the length of the full scarf
We must divide the scarf into 3 sections
150 ÷ 3 = 50
The three lengths we just found were 75cm, 112.5cm, and 50cm
Add all of the lengths up to find the final length of the last scarf
75 + 112.5 + 50 = 237.5cm
The Final scarf length is 237.5cm

do you have to rent to have the cost of the
rental be the same. Write and solve an
equation.
The equations are H = 4x + 60 and P = 8x + 20. We need to rent 10 tables to ensure that the cost of the rental will be the same.
What is system of equations?A system of equations in algebra consists of two or more equations and looks for common answers to the equations. "A set of equations satisfied by the same set of variables is called a system of linear equations."
Let us suppose tables as x.
Given that,
The happy party rents tables for $4 per table plus a delivery fee of 60. This is expressed as:
H = 4x + 60
Party Rental rents tables for $8 per table plus a $20 delivery fee.
P = 8x + 20
To get the same cost of the rent:
H = P
4x + 60 = 8x + 20
60 - 20 = 8x - 4x
40 = 4x
x = 10

Two surfaces are called orthogonal at a point of intersection P if their normals are perpendicular atthat point.Show that surfaces with equations F(x; y; z) = 0 and G(x; y; z) = 0 are orthogonal at a point Pwhere gradient of F = not equal to 0 and gradient of G is not equal to 0 if and only ifFxGx + FyGy + FzGz = 0 at P :use the above to show that z^2=x^2+y^2 and x^2+y^2+z^2=r^2 are orthogonal on every point of intersection.
by using the condition for orthogonality between surfaces and applying it to the given equation \(z^{2}\) = \(x^{2}\) + \(y^{2}\) and \(x^{2}\) + \(y^{2}\) + \(z^{2}\) = \(r^{2}\) are orthogonal at every point of intersection.
Let's consider the surfaces F(x, y, z) = 0 and G(x, y, z) = 0, where the gradients of F and G are non-zero at the point of intersection P. To prove that the surfaces are orthogonal at P, we need to show that their dot product, FxGx + FyGy + FzGz, is equal to zero at P.
The dot product of the gradients can be written as FxGx + FyGy + FzGz. If this expression evaluates to zero at P, it implies that the gradients are perpendicular, and therefore the surfaces are orthogonal at P.
Now, let's apply this result to the surfaces \(z^{2}\) = \(x^{2}\) + \(y^{2}\) and \(x^{2}\) + \(y^{2}\) + \(z^{2}\) = \(r^{2}\). Taking the gradients of these surfaces, we find that the dot product FxGx + FyGy + FzGz is equal to 2\(z^{2}\) + 2(\(x^{2}\) + \(y^{2}\) + \(z^{2}\)), which simplifies to 3\(z^{2}\) + 2(\(x^{2}\) + \(y^{2}\)).
Since this expression is equal to zero for all points (x, y, z) satisfying the equation of the second surface, \(x^{2}\) + \(y^{2}\) + \(z^{2}\) = \(r^{2}\), we can conclude that the surfaces \(z^{2}\) = \(x^{2}\) + \(y^{2}\) and \(x^{2}\) + \(y^{2}\)+ \(z^{2}\) = \(r^{2}\) are orthogonal at every point of intersection
