Equations are used to relate equal expressions.

The missing term is: \(\mathbf{ m -1}\)

The equation is given as:

\(\mathbf{\frac{m - n}{m^2 - n^2} + \frac{?}{(m -1)(m -n)} = \frac{2m}{m^2 - n^2}}\)

Express \(\mathbf{m^2 - n^2\ as\ (m - n)(m + n)}\)

So, we have:

\(\mathbf{\frac{m - n}{(m - n)(m + n)} + \frac{?}{(m -1)(m -n)} = \frac{2m}{(m - n)(m + n)}}\)

Multiply through by \(\mathbf{m - n}\)

\(\mathbf{\frac{m - n}{m + n} + \frac{?}{m -1} = \frac{2m}{m + n}}\)

Collect like terms

\(\mathbf{ \frac{?}{m -1} = \frac{2m}{m + n} - \frac{m - n}{m + n}}\)

Take LCM

\(\mathbf{ \frac{?}{m -1} = \frac{2m - m + n}{m + n} }\)

\(\mathbf{ \frac{?}{m -1} = \frac{m + n}{m + n} }\)

Divide \(\mathbf{ \frac{m + n}{m + n} }\)

\(\mathbf{ \frac{?}{m -1} = 1}\)

Cross multiply

\(\mathbf{ ? =(m -1)\times 1}\)

\(\mathbf{ ? =m -1}\)

Hence, the missing term is: \(\mathbf{ m -1}\)

The average velocities for the given time periods has been calculated and the instantaneous velocity when t = 2 is -24 ft/s.

To find the average velocity for the given time periods, we need to calculate the change in position divided by the change in time. The formula for average velocity is:

Average Velocity = (Δy) / (Δt)

For the time period of 0.5 seconds:

Substituting t = 2 and t = 2.5 into the equation \(y = 40t - 16t^{2}\), we have:

\(y1 = 40(2) - 16(2^{2}) = 80 - 64 = 16 ft\)

\(y2 = 40(2.5) - 16(2.5^2) = 100 - 100 = 0 ft\)

Δy = y2 - y1 = 0 - 16 = -16 ft

Δt = 0.5 seconds

Average Velocity = (Δy) / (Δt) = (-16 ft) / (0.5 s) = -32 ft/s

For the time period of 0.1 seconds:

Substituting t = 2 and t = 2.1, we have:

\(y1 = 40(2) - 16(2^{2}) = 80 - 64 = 16 ft\\ y2 = 40(2.1) - 16(2.1^{2}) = 84 - 72.24 = 11.76 ft\)

Δy = y2 - y1 = 11.76 - 16 = -4.24 ft

Δt = 0.1 seconds

Average Velocity = (Δy) / (Δt) = (-4.24 ft) / (0.1 s) = -42.4 ft/s

For the time period of 0.05 seconds:

Substituting t = 2 and t = 2.05, we have:

\(y1 = 40(2) - 16(2^{2}) = 80 - 64 = 16 ft\\ y2 = 40(2.05) - 16(2.05^{2}) = 81 - 68.56 = 12.44 ft\)

Δy = y2 - y1 = 12.44 - 16 = -3.56 ft

Δt = 0.05 seconds

Average Velocity = (Δy) / (Δt) = (-3.56 ft) / (0.05 s) = -71.2 ft/s

For the time period of 0.01 seconds:

Substituting t = 2 and t = 2.01, we have:

\(y1 = 40(2) - 16(2^2) = 80 - 64 = 16 ft\\ y2 = 40(2.01) - 16(2.01^2) = 80.4 - 64.3216 = 16.0784 ft\)

Δy = y2 - y1 = 16.0784 - 16 = 0.0784 ft

Δt = 0.01 seconds

Average Velocity = (Δy) / (Δt) = (0.0784 ft) / (0.01 s) = 7.84 ft/s

To find the instantaneous velocity when t = 2, we need to calculate the derivative of the position function y(t) with respect to t.

Taking the derivative of \(y = 40t - 16t^{2}\) gives us the velocity function v(t):

\($v(t) = \frac{{d}}{{dt}} (40t - 16t^2) = 40 - 32t$\)

Substituting t = 2 into v(t), we have:

v(2) = 40 - 32(2) = 40 - 64 = -24 ft/s

Therefore, the instantaneous velocity when t = 2 is -24 ft/s.

Answer: The measure of angle C in degrees and rounded to 1 decimal place is approximately 131.8.

Explanation: In triangle ABC, a = 6, b = 9 & c = 11. To find the measure of angle C in degrees and rounded to 1 decimal place, we can use the Law of Cosines. The Law of Cosines states that for any triangle ABC:

\($$c^2 = a^2 + b^2 - 2ab \cos(C)$$\\Rearranging the equation:$$\cos(C) = \frac{a^2 + b^2 - c^2}{2ab}$$\)

Substituting the given values :

\($$\cos(C) = \frac{6^2 + 9^2 - 11^2}{2(6)(9)}$$\\Solving for cos(C): $$\cos(C) = \frac{-2}{3}$$\)

Now, using the inverse cosine function, we can find the value of C in degrees:

\($$C = \cos^{-1}\left(\frac{-2}{3}\right)$$\\ Rounding to 1 decimal place:\\$$C \approx 131.8^\circ$$\)

Therefore, the measure of angle C in degrees and rounded to 1 decimal place is approximately 131.8.

Answer:

John has 18 pieces of paper.

Larry has 32 pieces of paper.

Step-by-step explanation:

Let \(l\) be how many pieces of paper Larry has and \(j\) be how many pieces of paper John has.

We get:

\(j+14=l\)

\(j+l=50\)

\(j+j+14=50\\\\2j+14=50\)

Subtract 14 from both sides

\(2j=36\)

Divide both sides by 2

\(j=18\)

John has 18 pieces of paper.

\(j+14=l\\\\18+14=l\\\\l=32\)

Larry has 32 pieces of paper.

The possible dimensions of the rectangle are 6 inches by 8 inches, and the answer is D).

What is the area of rectangle?

The area of a rectangle is calculated by multiplying the length of the rectangle by its width. That is:

Area of rectangle = length × width

A = l × w

where A represents the area of the rectangle, l represents its length, and w represents its width.

Let's assume the rectangle has length "L" and width "W". We know that the area of the rectangle is 48 sq. in., so:

L * W = 48

We also know that the perimeter of the rectangle is 28 in., so:

2L + 2W = 28

L + W = 14

Now we can use these two equations to solve for L and W. One approach is to use substitution:

L = 14 - W (from the second equation)

(14 - W) * W = 48 (substituting for L in the first equation)

14W - W² = 48

W² - 14W + 48 = 0

(W - 6)(W - 8) = 0

So the possible values for W are 6 and 8. If W is 6, then L must be 8:

6 * 8 = 48 (the area checks out)

2(6) + 2(8) = 28 (the perimeter checks out)

Therefore, the possible dimensions of the rectangle are 6 inches by 8 inches, and the answer is D).

To check to see if a point is a solution to a system of two linear equations, you can plug the points into each equation. If the solution point causes the equation toequal itself, it is correct.

Based on the given information, we cannot prove that △EFG and △KLM are similar using the SSS or SAS similarity theorems. The correct answer is option D) No, they cannot be proven similar by SSS or SAS.

To determine if the triangles △EFG and △KLM can be proven similar using the SSS (Side-Side-Side) or SAS (Side-Angle-Side) similarity theorems, we need to compare their corresponding sides and angles.

SSS Similarity Theorem states that if the lengths of the corresponding sides of two triangles are proportional, then the triangles are similar.

SAS Similarity Theorem states that if two corresponding sides of two triangles are proportional, and the included angles are congruent, then the triangles are similar.

Let's examine the given information:

Side lengths of △EFG: EF = 18, EG = 24, FG = 15.

Side lengths of △KLM: KL = 6, KM = 8, LM = 5.

By comparing the side lengths, we can see that they are not proportional. For example, the ratio of EF/KL is 18/6 = 3, while the ratio of EG/KM is 24/8 = 3. Therefore, the corresponding sides of △EFG and △KLM are not proportional, which means we cannot establish similarity using the SSS theorem.

Now, let's consider the SAS theorem. For this, we also need to compare the included angles.

Angles of △EFG: ∠EFG, ∠EFG, ∠EGF.

Angles of △KLM: ∠KLM, ∠KML, ∠KLM.

The given information states that ∠EFG and ∠KLM are congruent. However, we don't have any information about the other angles. Without knowing the congruency of the remaining angles, we cannot establish similarity using the SAS theorem

We can use the Pythagorean Theorem to find the height of the cylinder

We have

height  = √ [ 5^2 - 2^2 ]  = √[25 - 4]   =  √21  units

The scalar λ can be given a value of -15.

We apply the principle of dot product and cross product between vectors to arrive at the solution.

The Dot Product of two vectors A and B is defined as:

A.B = |A|*|B|*Cosθ

where |A| and |B| are the magnitudes of the respective vectors.

Similarly, the Cross Product is defined as:

A×B = |A|*|B|*Sinθ * n,

where n is a vector perpendicular to both A and B.

Thus, A.B is a scalar quantity, but A×B is a vector.

We will apply both principles to arrive at a solution.

A+B and A-λB are perpendicular to each other.

Thus,

(A+B).(A-λB) = 0, since Cos90 = 0

A.A - λ(A.B) + B.A - λ(B.B) = 0

The dot product of a vector with itself is just the product of their magnitudes, as the angle between them is 0.

|A|² - λ|B|² + (1-λ)A.B = 0

A.B = |A|*|B| Cos 120 = -|A||B|/2 = -3|B|²/2               (Since |A| = 3|B|)

=> The prior equation can be further simplified as:

9|B|² - λ|B|² +(1-λ)(-3|B|²/2 ) = 0

|B|² {9 - λ +(3λ - 3)/2} = 0

Since |B| cannot be zero for obvious reasons, the rest of the expression is zero.

9 - λ +(3λ - 3)/2 = 0

18 - 2 λ + 3 λ - 3 = 0

λ = -15

Thus the scalar λ is equal to 15 for the two vectors to be perpendicular.

The given curves are `y = x + 1, y = 0, x = 0 and x = 4` and we are supposed to find the volume `V` of the solid obtained by rotating the region bounded by the given curves about the x-axis.

The region is shown below:Region bounded by y = x + 1, y = 0, x = 0 and x = 4We can observe that the region is a right-angled triangle with perpendicular `4` and base `1`. Now, we need to rotate this right-angled triangle about the x-axis to form a solid of revolution. The solid of revolution obtained is shown below:Solid of revolution obtained by rotating the region about the x-axis Since the region is rotated about the x-axis, the axis of rotation is `x-axis`.

So, the formula for volume of the solid of revolution is given by:`V = pi * ∫[a, b] y^2 dx`Here, the limits of integration are `a = 0` and `b = 4`.We need to express `y` in terms of `x`.Since, `y = x + 1`, we get`x = y - 1`Substituting this value of `x` in `x = 4`, we get`y - 1 = 4``y = 5`So, the limits of integration for `y` are `0 to 5`.So, we have to evaluate the integral:`V = pi * ∫[0, 5] (y - 1)^2 dx`

Simplifying this, we get:`V = pi * ∫[0, 5] (y^2 - 2y + 1) dy``V = pi * (∫[0, 5] y^2 dy - 2∫[0, 5] y dy + ∫[0, 5] dy)``V = pi * [y^3/3 - y^2 + y] [0, 5]``V = pi * [(5^3/3 - 5^2 + 5) - (0)]``V = pi * [(125/3 - 25 + 5)]``V = pi * [100/3]`

Therefore, the volume `V` of the solid obtained by rotating the region bounded by the given curves about the x-axis is `V = (100/3) pi` (in cubic units).
