find equation tan line curved defined by x⁴+2xy+y4=21 points (1,2)

Answers

Answer 1

The equation of the tangent line to the curve defined by x⁴ + 2xy + y⁴ = 21 at the point (1, 2) is y = (-4/17)x + 38/17.

To find the equation of the tangent line to the curve defined by the equation x⁴ + 2xy + y⁴ = 21 at the point (1, 2), we need to calculate the derivative of the equation, evaluate it at the given point, and use the point-slope form of a line to determine the equation of the tangent line. The equation of the tangent line is y = 8x - 6.

To find the equation of the tangent line, we start by taking the derivative of the given equation with respect to x. Differentiating each term separately, we have:

4x³ + 2y + 2xy' + 4y³y' = 0.

Next, we substitute the x and y values from the given point (1, 2) into the derivative equation. We obtain:

4(1)³ + 2(2) + 2(1)(y') + 4(2)³(y') = 0,

4 + 4 + 2y' + 4(8)(y') = 0,

2y' + 32y' = -8,

34y' = -8,

y' = -8/34,

y' = -4/17.

The derivative y' represents the slope of the tangent line at the point (1, 2). Therefore, the slope is -4/17.

Using the point-slope form of a line, y - y₁ = m(x - x₁), we substitute the coordinates of the given point (1, 2) and the slope -4/17 into the equation. This gives us:

y - 2 = (-4/17)(x - 1),

y - 2 = (-4/17)x + 4/17,

y = (-4/17)x + 4/17 + 2,

y = (-4/17)x + 4/17 + 34/17,

y = (-4/17)x + 38/17.

Do not round until the final answer. Then round to the nearest tenth as needed.) (B) Use the least squares line to estimate the annual production of motor vehicles in the country in 2011. The annual production in 2011 is approximately vehicles.

Answers

To find the least squares line for the given data, we will perform linear regression using the method of least squares. We'll consider the years (x-values) as the independent variable and the motor vehicle production (y-values) as the dependent variable.

Let's first calculate the necessary sums:

n = number of data points = 8

Σx = sum of x-values = 1997 + 1998 + ... + 2004

Σy = sum of y-values = 1578 + 1628 + ... + 5092

Σxy = sum of x*y = (1997 * 1578) + (1998 * 1628) + ... + (2004 * 5092)

Σ[tex]x^2[/tex] = sum of x^2 = (1997^2) + (1998^2) + ... + (2004^2)

Once we have these sums, we can use the following formulas to calculate the coefficients of the least squares line:

slope, m = (n * Σxy - Σx * Σy) / (n * Σx^2 - (Σx)^2)

intercept, b = (Σy - m * Σx) / n

Let's calculate these values:

Σx = 1997 + 1998 + 1999 + 2000 + 2001 + 2002 + 2003 + 2004 = 16016

Σy = 1578 + 1628 + 1805 + 2009 + 2332 + 3251 + 4444 + 5092 = 22139

Σxy = (1997 * 1578) + (1998 * 1628) + ... + (2004 * 5092) = 24979962

Σ[tex]x^2[/tex] = ([tex]1997^2[/tex]) + (1998^2) + ... + (2004^2) = 32096048

Now we can substitute these values into the formulas:

slope, m = (8 * 24979962 - 16016 * 22139) / (8 * 32096048 - (16016)^2)

intercept, b = (22139 - m * 16016) / 8

Performing the calculations:

slope, m ≈ 0.8259

intercept, b ≈ -161423.375

Therefore, the equation of the least squares line is:

y ≈ 0.8259x - 161423.375

To estimate the annual production of motor vehicles in the country in 2011, we substitute x = 2011 into the equation:

y ≈ 0.8259 * 2011 - 161423.375

Calculating this expression:

y ≈ 1661.136 - 161423.375

y ≈ -159762.239

The estimated annual production of motor vehicles in the country in 2011 is approximately -159,762 vehicles.

Wse a graphing utity to groph the equation and graphically approximate the values of \( x \) that satisfy the specified inequalitieg. Then solve each inequality algebraically. \[ y=x^{3}-x^{2}-16 x+16

Answers

The given inequality is y ≤ 0.We will use a graphing utility to graph the equation and approximate the values of x that satisfy the inequality.

In order to graph the given inequality, we need to graph the equation y = x³ - x² - 16x + 16 first. We can use the graphing utility to graph this equation as shown below:

graph{y=x^3-x^2-16x+16 [-10, 10, -5, 5]}

From the graph, we can see that the values of x that satisfy the inequality y ≤ 0 are the values for which the graph of the equation y = x³ - x² - 16x + 16 is below the x-axis.

We can approximate these values by looking at the x-intercepts of the graph. We can see from the graph that the x-intercepts of the graph are at x = -2, x = 2, and x = 4.

Therefore, the values of x that satisfy the inequality y ≤ 0 are approximately x ≤ -2, -2 ≤ x ≤ 2, and 4 ≤ x.

To solve the inequality algebraically, we need to find the values of x that make y ≤ 0. We can do this by factoring the expression y = x³ - x² - 16x + 16:

y = x³ - x² - 16x + 16= x²(x - 1) - 16(x - 1)= (x - 1)(x² - 16)= (x - 1)(x - 4)(x + 4)

The inequality y ≤ 0 is satisfied when the value of y is less than or equal to zero. Therefore, we need to find the values of x that make the expression (x - 1)(x - 4)(x + 4) ≤ 0.

To find these values, we can use the method of sign analysis. We can make a sign table for the expression (x - 1)(x - 4)(x + 4) as shown below:x-441Therefore, the values of x that make the expression (x - 1)(x - 4)(x + 4) ≤ 0 are approximately x ≤ -4, 1 ≤ x ≤ 4.

Therefore, the solution to the inequality y ≤ 0 is approximately x ≤ -2, -2 ≤ x ≤ 2, and 4 ≤ x, or -4 ≤ x ≤ 1 and 4 ≤ x.

{x²+2x-2 if x < 0
Let F(x) = {2x² + 3x -2 if 0 ≤ x < 3
{-2x²-3x - 1 if x ≥ 3

Answers

At x = 0, the function f(x) is best described as having a "corner" or a "discontinuity" due to a change in the definition of the function at that point.

The function f(x) is defined differently for different ranges of x. For x < 0, f(x) = x^2 + 2x - 2. For 0 ≤ x < 3, f(x) = 2x^2 + 3x - 2. And for x ≥ 3, f(x) = -2x^2 - 3x - 1.

At x = 0, the function has a change in its definition. For x < 0, the expression x^2 + 2x - 2 is used to define f(x), while for x ≥ 0, the expression 2x^2 + 3x - 2 is used. Since 0 is the boundary between these two ranges, the function changes its definition at x = 0.

This change in definition results in a discontinuity or a "corner" in the graph of the function at x = 0. It means that the behavior of the function on the left side of 0 is different from its behavior on the right side of 0. Therefore, at x = 0, the function f(x) is best described as having a corner or a discontinuity.

Answers

Neither option (c) nor option (d) is perpendicular to \(\vec{A}\).

Given that the vector \( \vec{A}=2 \tilde{a}_{s}-5 \tilde{a}_{a} \) is perpendicular to the vectors given as options.

Now, to find which vector is perpendicular to \(\vec{A}\), we can find the dot product between \(\vec{A}\) and each option and check which one gives 0.

Dot Product: If \(\vec{u} = u_{x} \tilde{a}_{x}+u_{y} \tilde{a}_{y}+u_{z} \tilde{a}_{z}\) and \(\vec{v} = v_{x} \tilde{a}_{x}+v_{y} \tilde{a}_{y}+v_{z} \tilde{a}_{z}\) are two vectors, then the dot product of the two vectors is given by:\(\vec{u} \cdot \vec{v} = u_{x}v_{x} + u_{y}v_{y} + u_{z}v_{z}\)

For option (c), the vector is \( 2 \tilde{a}_{x}+2 \tilde{a}_{y}+5 \tilde{a}_{z} \)

Therefore,\(\vec{A} \cdot \vec{c} = 2(2) - 5(5) + 0 = -21\) As the dot product is not zero, option (c) is not perpendicular to \(\vec{A}\).

Hence, option (c) is incorrect. Now, we can check option (d) For option (d), the vector is \( 5 \tilde{a}_{x}+2 \dot{a}_{y} \) Therefore,\(\vec{A} \cdot \vec{d} = 2(5) - 5(0) + 0 = 10\). As the dot product is not zero, option (d) is not perpendicular to \(\vec{A}\). Hence, option (d) is incorrect.

Therefore, neither option (c) nor option (d) is perpendicular to \(\vec{A}\).

For the cost and price functions below, find a) the number, q, of units that produces maxim C(q)=70+14q;p=78−2q a) The number, q, of units that produces maximum profit is q= b) The price, p, per unit that produces maximum profit is p=$ c) The maximum profit is P=$___

Answers

a) The number, q, of units that produces maximum profit is q = 0

            b) The price, p, per unit that produces maximum profit is p = $78

             c) The maximum profit is P = $702.

Given that, cost function C(q) = 70 + 14q and price function P(q) = 78 - 2q.

We have to find the number q of units that produce maximum C(q) and the price p per unit that produces maximum profit, and the maximum profit is P(q).

The formula to calculate profit is Profit = Revenue - Cost.

Thus, we can say, Profit = P(q) * q - C(q).

Part (a)To find the number q of units that produces maximum C(q), we differentiate the cost function with respect to q and equate it to 0.

This is because at the maximum value of C(q), the slope of the curve is zero.

Therefore, dC/dq = 14 = 0

So, q = 0 is the value that maximizes the function C(q).

Part (b)To find the price per unit that produces maximum profit, we differentiate the profit function with respect to q and equate it to 0.

This is because at the maximum value of P(q), the slope of the curve is zero.

Therefore,dP/dq = -2 = 0So, q = 0 is the value that maximizes the function P(q).

We know that P(q) = 78 - 2q.Substituting q = 0, we get,P(0) = 78 - 2(0)P(0) = 78

Therefore, the price per unit that produces maximum profit is $78.

Part (c)To find the maximum profit, we use the value of q obtained from part (b) and substitute it in the Profit equation.

Profit = P(q) * q - C(q) = (78 - 2q)q - (70 + 14q) = 78q - 2q² - 70 - 14q = -2q² + 64q - 70

Now, we differentiate the profit function with respect to q and equate it to 0 to obtain the value of q that maximizes the function.

This is because at the maximum value of Profit, the slope of the curve is zero.

dProfit/dq = -4q + 64 = 0So, q = 16 is the value that maximizes the function Profit.

To obtain the maximum profit, we substitute q = 16 in the Profit equation.

Profit = -2q² + 64q - 70= -2(16)² + 64(16) - 70= $702

Therefore, the maximum profit is $702..

a) The number, q, of units that produces maximum profit is q = 0

            b) The price, p, per unit that produces maximum profit is p = $78

             c) The maximum profit is P = $702.

Answers

Given 2y + 14y = 5xIf y(0) = 0.5, we want to find y(3) using the midpoint method and step size of h = 15.

The midpoint method is given as follows:yi+1 = yi + hf(xi + h/2, yi + h/2f(xi, yi))where f(xi, yi) is the derivative of the given function at (xi, yi).To apply the midpoint method to the given differential equation, we need to rewrite it in the form y' = f(x, y). To do this, we first isolate y' on one side:2y + 1 = 5x - 4yy' = (5x - 4y)/2

Now we can substitute this expression for y' into the midpoint formula and simplify: y1 = 0.5,

h = 15

y2 = y1 + hf(x1 + h/2, y1 + h/2f(x1, y1))

= 0.5 + 15(5(0) - 4(0.5)/2)

= 0.5 - 15

= -14.5

y3 = y2 + hf(x2 + h/2, y2 + h/2f(x2, y2))

= -14.5 + 15(5(15/2) - 4(-14.5)/2)

= -14.5 + 137.25

Water is pumped out of a holding tank at a rate of r(t) = 5-6e^-0.25t liters per minute, where t is in minutes since the pump started.

1. How much water was pumped out of the tank, 30 minutes after the pump started?
________
2. If the holding tank contains 1000 liters of water
when the pump is started, then how much water is in the tank 1 hour (60 minutes) after the pump has started?
_______

Answers

The volume of water in the tank 1 hour (60 minutes) after the pump has started is approximately 530.6 liters.

1) The rate at which water is being pumped out of the tank is given by:

r(t) = 5-6e^(-0.25t) liters per minute. The integral of r(t) from 0 to 30 will give the volume of water pumped out in the first 30 minutes of operation. So, the volume of water pumped out in 30 minutes is given by:
= ∫r(t)dt

= [5t + 24e^(-0.25t)]_0^30

= [5(30) + 24e^(-0.25(30))] - [5(0) + 24e^(-0.25(0))]

≈ 117.6 liters
The volume of water pumped out of the tank 30 minutes after the pump started is approximately 117.6 liters.

2) We need to find the volume of water left in the tank after 60 minutes of pump operation. Let V(t) be the tank's water volume at time t.

Then, V(t) satisfies the differential equation:

dV/dt = -r(t) and the initial condition:

V(0) = 1000.

We can use the method of separation of variables to solve this differential equation:
dV/dt = -r(t)

⇒ dV = -r(t)dt
Integrating both sides from t = 0 to t = 60, we get:
∫dV = -∫r(t)dt
⇒ V(60) - V(0)

= ∫[5 - 6e^(-0.25t)]dt

= [5t + 24e^(-0.25t)]_0^60

= [5(60) + 24e^(-0.25(60))] - [5(0) + 24e^(-0.25(0))]

≈ 530.6 liters
The volume of water in the tank 1 hour (60 minutes) after the pump has started is approximately 530.6 liters.

Answers

The low partition after the partitioning algorithm is completed is `(63,41,38,29)` and the high partition after the partition is `(80)`.

Given numbers \(=(63,80,41,64,38,29)\),

pivot \(=64\)

The low partition after the partitioning algorithm is completed is  `(63,41,38,29)` and the high partition after the partition is `(80)`.

Explanation:

The given numbers are:

\(=(63,80,41,64,38,29)\)

Pivot = 64

The steps to partition the above numbers are:

Choose the last element of the given array as the pivot element. In this case, pivot=64.

Partition the given array into two groups: a low group and a high group. The low group will contain all elements strictly less than the pivot element.

The high group will contain all elements greater than or equal to the pivot element.

Now partition the array around the pivot value (64). The result of the partitioning is that all the elements less than the pivot value (64) are moved to the left of it, and all the elements greater than the pivot value (64) are moved to the right of it. After partitioning, the array will look like this: `(63,41,38,29,64,80)`.

So, the low partition after the partitioning algorithm is completed is `(63,41,38,29)` and the high partition after the partition is `(80)`.

To analyze the stability of the given characteristic equation using the Routh-Hurwitz criterion, we need to arrange the equation in the form:

s^5 + 2s^4 + 24s^3 + 48s^2 - 25s - 50 = 0

The Routh table will have five rows since the equation is of fifth order. The first two rows of the Routh table are formed by the coefficients of the even and odd powers of 's' respectively:

Row 1: 1   24   -25

Row 2: 2   48   -50

Now, we can proceed to fill in the remaining rows of the Routh table. The elements in the subsequent rows are calculated using the formulas:

Row 3: (2*(-25) - 24*48) / 2 = -1232

Row 4: (48*(-1232) - (-25)*2) / 48 = 60325

Row 5: (-1232*60325 - 2*48) / (-1232) = 2

The number of sign changes in the first column of the Routh table is equal to the number of roots in the right half plane (RHP). In this case, there are two sign changes. Thus, there are two poles in the RHP. The remaining three poles are in the left half plane (LHP) or on the imaginary axis (jo poles).

Answers

We take the first term of the power series expansion, which gives us the first-order linear approximation. Hence, option (D) is correct

The given function is f(x) = 2/(1 - x).

To find an approximation for the function f(x) = 2/(1-x) for values of x near zero, we will use the linear approximation (1 + x)^k = 1 + kx.

We will find the first-order linear approximation of the given function near x = 0.

Therefore, we have to choose k and compute f(x) = 2/(1-x) in the form kx + 1.

Using the formula, (1 + x)^k = 1 + kx to find the linear approximation of f(x), we have:(1 - x)^(–1)

= 1 + (–1)x^1 + k(–1 - 0).

Comparing this equation with the equation 1 + kx, we have: k = –1.

Therefore, the first-order linear approximation of f(x) isf(x) = 1 – x + 1 + x,

which simplifies to f(x) = 2.

Since the first-order linear approximation of f(x) near x = 0 is 2, we can conclude that the correct option is O f(x) = 2 + 2x

Hence, option (D) is correct.

Note: To get the first-order linear approximation, we first expand the given function into a power series by using the formula (1 + x)^k.

Then, we take the first term of the power series expansion, which gives us the first-order linear approximation.

fz(2, 0, 3) = 0.

To evaluate the first partial derivatives of the function at the given point (2,0,3),

let's first differentiate the function f(x, y, z) = x²yz² with respect to x, y, and z one by one.

After that, we can substitute the point (2,0,3) into the derivative functions to obtain the desired partial derivatives of f(x,y,z) at the point (2,0,3).

Differentiation of f(x, y, z) = x²yz² with respect to x:

When we differentiate f(x, y, z) with respect to x, we assume that y and z are constants, and only x is the variable.

We apply the power rule of differentiation which states that the derivative of x^n with respect to x is nx^(n-1).

Using this rule, we obtain:

fx(x, y, z) = d/dx(x²yz²)

= 2xyz²

When we substitute (2,0,3) into fx(x, y, z),

we get:

fx(2, 0, 3) = 2(0)(3²) = 0

Differentiation of f(x, y, z) = x²yz² with respect to y:

When we differentiate f(x, y, z) with respect to y, we assume that x and z are constants, and only y is the variable.

We apply the power rule of differentiation which states that the derivative of y^n with respect to y is ny^(n-1).

Using this rule, we obtain:

fy(x, y, z) = d/dy(x²yz²) = x²z²(2y)

When we substitute (2,0,3) into fy(x, y, z), we get:

fy(2, 0, 3) = (2²)(3²)(2)(0) = 0

Differentiation of f(x, y, z) = x²yz² with respect to z:

When we differentiate f(x, y, z) with respect to z, we assume that x and y are constants, and only z is the variable.

We apply the power rule of differentiation which states that the derivative of z^n with respect to z is nz^(n-1).

Using this rule, we obtain:

fz(x, y, z) = d/dz(x²yz²) = x²(2yz)

When we substitute (2,0,3) into fz(x, y, z), we get:

fz(2, 0, 3) = (2²)(2)(3)(0) = 0

Therefore, the first partial derivatives of the function f(x,y,z) = x²yz² at the point (2,0,3) are:

fx(2, 0, 3) = 0fy(2, 0, 3) = 0fz(2, 0, 3) = 0.

Evaluate each of the following integrals.
⁰∫ −π sec(t)⋅tan(t)⋅ √5+4sec(t)dt

Answers

The integral ∫[0 to -π] sec(t)⋅tan(t)⋅ √(5+4sec(t)) dt  on evaluation is found to be ∫[0 to -π] sec(t)⋅tan(t)⋅ √(5+4sec(t)) dt = -2√6.

To evaluate this integral, we can start by applying the trigonometric identity sec^2(t) - 1 = tan^2(t) to rewrite the integrand. Rearranging the equation gives us sec^2(t) = tan^2(t) + 1.

Now let's substitute sec(t) with √(tan^2(t) + 1) in the original integral. The integrand becomes √(tan^2(t) + 1)⋅tan(t)⋅√(5 + 4√(tan^2(t) + 1)).

Next, we can make a substitution by letting u = tan(t). Then du = sec^2(t) dt. The integral transforms into ∫[0 to -π] u⋅ √(5 + 4√(u^2 + 1)) du.

By simplifying the expression under the square root, we have √(5 + 4√(u^2 + 1)) = √(2√(u^2 + 1))^2 = 2√(u^2 + 1).

Now the integral becomes ∫[0 to -π] 2u^2√(u^2 + 1) du.

At this point, we can make a trigonometric substitution by letting u = √(2)sinh(v). Then du = √(2)cosh(v)dv.

After making the substitution and simplifying, the integral becomes ∫[0 to -π] 2(2sinh^2(v))⋅(√2sinh(v)⋅cosh(v))⋅(√(2)⋅cosh(v)) dv.

Simplifying further, we get ∫[0 to -π] 8sinh^3(v)cosh^2(v) dv.

Using the identity sinh^2(v) = (cosh(2v) - 1) / 2, we can rewrite the integral as ∫[0 to -π] 4sinh^3(v)(cosh(2v) - 1) dv.

By expanding and simplifying the integrand, the integral becomes ∫[0 to -π] 4(cosh^2(v)sinh(v) - sinh^3(v)) dv.

Now, we evaluate each term separately: ∫[0 to -π] cosh^2(v)sinh(v) dv and ∫[0 to -π] sinh^3(v) dv.

Evaluating these integrals gives us -2√6.

Hence, the final answer for the given integral is ∫[0 to -π] sec(t)⋅tan(t)⋅ √(5+4sec(t)) dt = -2√6.

3.) Give 3 example problems with solutions using the
slope formula.

Answers

Here are three example problems that involve using the slope formula, along with their solutions:

Problem 1:

Find the slope of the line passing through the points (2, 3) and (5, 7).

The slope (m) can be found using the formula:

m = (y2 - y1) / (x2 - x1)

Let's substitute the given coordinates into the formula:

m = (7 - 3) / (5 - 2)

m = 4 / 3

Therefore, the slope of the line passing through the points (2, 3) and (5, 7) is 4/3.

Problem 2:

Determine the slope of the line that is parallel to the line represented by the equation y = 2x + 5.

The equation of a line in slope-intercept form is given by y = mx + b, where m represents the slope.

Since we are looking for a line that is parallel to y = 2x + 5, the parallel line will have the same slope.

Therefore, the slope of the line parallel to y = 2x + 5 is 2.

Problem 3:

Given the equation of a line as 3x - 4y = 8, find the slope of the line.

To find the slope, we can rearrange the equation into slope-intercept form (y = mx + b).

Let's isolate y:

3x - 4y = 8

-4y = -3x + 8

y = (3/4)x - 2

Now we can observe that the coefficient of x represents the slope.

Therefore, the slope of the line represented by the equation 3x - 4y = 8 is 3/4.

Answers

The low partition index is:[tex]\[\text{low partition}=6\][/tex]

Therefore, the pivot element is 70, and the low partition index is 6.

Quicksort is an algorithm that is based on the divide-and-conquer approach. In this approach, the problem is divided into several subproblems that are solved independently. This algorithm is used to sort a given sequence of elements.

The quicksort algorithm chooses an element called the pivot element and divides the sequence into two parts, one that contains elements that are less than the pivot element and the other that contains elements that are greater than the pivot element.

The pivot element is then placed in its correct position. This process is repeated recursively for the two partitions obtained until the entire sequence is sorted.

The given sequence of elements is: [tex]\[\text{numbers}=(45,22,49,27,70,92,66,98,78)\][/tex]

Let us apply the Partition (numbers, 4, 8) method.

The method takes three arguments: the list of numbers, the start index, and the end index.

The start index is 4, and the end index is 8. Therefore, the sequence of elements from the 5th position to the 9th position will be partitioned. The pivot element will be the middle element of this sequence of elements. Thus, the pivot element is:\[\text{pivot}=70\]

The Partition method will divide the given sequence of elements into two parts. One part will contain the elements that are less than the pivot element, and the other part will contain the elements that are greater than the pivot element.

The index of the last element in the first partition is called the low partition. The index of the first element in the second partition is called the high partition.

The low partition index and the high partition index will be returned by the Partition method.

The low partition index is:[tex]\[\text{low partition}=6\][/tex]

Therefore, the pivot element is 70, and the low partition index is 6.

The quicksort algorithm can now be applied to the two partitions obtained until the entire sequence is sorted.

The valuated integral produces the result e^x.

To evaluate the limit as n approaches infinity of (1 + 1/n)^nx, where x is a constant, we can rewrite the expression using the concept of the natural exponential function.

We know that e^x is the limit as n approaches infinity of (1 + 1/n)^nx, so we can rewrite the given expression as:

lim(n→∞) (1 + 1/n)^nx = lim(n→∞) (e^(1/n))^nx.

lim(n→∞) e^((1/n) * nx).

Simplifying the exponent:

(1/n) * nx = x.

Therefore, the expression becomes:

lim(n→∞) e^x.

Since e^x does not depend on n, the limit as n approaches infinity will be the same as e^x:

Find the length of \( \overline{D F} \) if the following are true. (a) \( D E=16 \) and \( E F=12 \) \[ D F= \] (b) \( D E=7 \) and \( E F=5 \)

Answers

The, (overline{DF} ) has a length of ( sqrt{74} ) units in case (b).

To find the length of (overline {DF} ) in both cases, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

(a) Given ( DE = 16) and ( EF = 12 ), we can find ( DF ) using the Pythagorean theorem:

\[ DF^2 = DE^2 + EF^2 \]

\[ DF^2 = 16^2 + 12^2 \]

\[ DF^2 = 256 + 144 \]

\[ DF^2 = 400 \]

Taking the square root of both sides, we get:

[ DF = sqrt{400} = 20 ]

Therefore, (overline{DF} ) has a length of 20 units in case (a).

(b) Given ( DE = 7 ) and ( EF = 5 ), we can apply the Pythagorean theorem again to find ( DF ):

\[ DF^2 = DE^2 + EF^2 \]

\[ DF^2 = 7^2 + 5^2 \]

\[ DF^2 = 49 + 25 \]

\[ DF^2 = 74 \]

Taking the square root of both sides, we have:

[ DF =sqrt{74} ]

Therefore, (overline{DF} ) has a length of (sqrt{74} ) units in case (b).
