This expression represents the Wronskian of the given set of functions {y1, y2}.Wronskian = e^2x * (cos(sqrt(x)) * sin(sqrt(x)) + (1/2)cos(sqrt(x)) * cos(sqrt(x)) - (1/2)sin(sqrt(x)) * sin(sqrt(x)))

To compute the Wronskian of a set of functions {y1, y2}, we need to evaluate the determinant of the matrix formed by the derivatives of these functions.

In this case, we have {y1, y2} = {e^x cos(sqrt(x)), e^x sin(sqrt(x))}.

To find the derivatives, we apply the chain rule. The derivatives of y1 and y2 with respect to x are:

y1' = (e^x cos(sqrt(x)))' = e^x cos(sqrt(x)) - (1/2)e^x sin(sqrt(x))

y2' = (e^x sin(sqrt(x)))' = e^x sin(sqrt(x)) + (1/2)e^x cos(sqrt(x))

Now, we form the matrix by arranging the derivatives:

| e^x cos(sqrt(x)) - (1/2)e^x sin(sqrt(x)) |

| e^x sin(sqrt(x)) + (1/2)e^x cos(sqrt(x)) |

Taking the determinant of this matrix, we have:

Wronskian = (e^x cos(sqrt(x)) - (1/2)e^x sin(sqrt(x))) * (e^x sin(sqrt(x)) + (1/2)e^x cos(sqrt(x)))

Expanding and simplifying the expression, we get:

Wronskian = e^2x * (cos(sqrt(x)) * sin(sqrt(x)) + (1/2)cos(sqrt(x)) * cos(sqrt(x)) - (1/2)sin(sqrt(x)) * sin(sqrt(x)))

Further simplification may not be possible without specific values of x, but this expression represents the Wronskian of the given set of functions {y1, y2}.

Answer:

x inches = 46 inches

2x inches = 92 inches

(7x - 4) inches = 318 inches

Step-by-step explanation:

The perimeter of the triangle is the sum of all three sides. Therefore,

x + 2x + (7x - 4) = 456 inches

10x - 4 = 456

10x = 460

x = 46 inches

Now, we find the other remaining sides.

2x inches = 2(46) inches = 92 inches

(7x - 4) inches = (7(46) - 4) inches = (322 - 4) inches = 318 inches

So, the final answer is

x inches = 46 inches

2x inches = 96 inches

(7x - 4) inches = 318 inches

Answer: The third one

Step-by-step explanation:

That system has the same equation, but a different solution, meaning the lines can never intersect.

We can also convert it into slope-intercept form.

y = -2x + 9

y = -2x + 5

Different slope and same y-intercept = NO SOLUTION

Answer:

2x + y = 9

2x + y = 5

Step-by-step explanation:

No solutions for 2 lines will only happen when the lines are parallel and never touch.  So there are no solutions.

Lines are parallel when slopes are the same.

The equations cannot be the same just the slopes are the same.  

Let's rearrange this set of equations into y=mx+b so we can see what the slope m is:

2x + y = 9           and               2x + y = 5

y= -2x +9                                 y= - 2x +5

You can see the lines are different but have the slopes so they are parallel and no solutions.

The function  g(f(3)) = g(-31) = -65

Given that g(n) = 2n - 3 and f(n) = -n³ - 4. We need to find g(f(3)).Step-by-step explanation:

First, we need to find f(3),

we substitute n = 3 in f(n) = -n³ - 4

to getf(3) = -3³ - 4 = -27 - 4 = -31

Now, we substitute this value of f(3) in g(n) = 2n - 3

to getg(f(3)) = g(-31)We substitute n = -31 in g(n) = 2n - 3 to getg(-31) = 2(-31) - 3 = -62 - 3 = -65.

The equation of the perpendicular bisector of the line segment with endpoints (-7, 2) and (-1, -6) is y = (3/4)x + 1.

To find the equation of the perpendicular bisector of a line segment, we need to determine the midpoint of the line segment and the slope of the line segment. The perpendicular bisector will have a negative reciprocal slope compared to the line segment and will pass through the midpoint.

Given the endpoints (-7, 2) and (-1, -6), we can find the midpoint using the midpoint formula:

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

Midpoint = ((-7 + (-1))/2, (2 + (-6))/2)

= (-8/2, -4/2)

= (-4, -2)

The midpoint of the line segment is (-4, -2).

Next, we need to find the slope of the line segment using the slope formula:

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

Slope = (-6 - 2)/(-1 - (-7))

= (-6 - 2)/(-1 + 7)

= (-8)/(6)

= -4/3

The slope of the line segment is -4/3.

Since the perpendicular bisector has a negative reciprocal slope, the slope of the perpendicular bisector will be 3/4.

Now, we can use the midpoint (-4, -2) and the slope 3/4 in the point-slope form of a line to find the equation of the perpendicular bisector:

y - y1 = m(x - x1)

y - (-2) = (3/4)(x - (-4))

y + 2 = (3/4)(x + 4)

y + 2 = (3/4)x + 3

Answer:

∠ O = 55° , ∠ A = 90°

Step-by-step explanation:

2

the figure has opposite sides parallel and is therefore a parallelogram.

• opposite angles in a parallelogram are congruent, then

∠ O = ∠ Q = 55°

3

the sum of the interior angles of a quadrilateral is 360°

sum the angles and equate to 360°

∠ A + 70° + 110° + 90° = 360°

∠ A + 270° = 360° ( subtract 270° from both sides )

∠ A = 90°

The length of time that it will take for each of the workout sessions would be: Plan A = 1.5 hours, and Plan B =  0.5 hours.

The length of the sessions can be obtained by first obtaining drawing a system of equations for the two cases. On Wednesday, we can represent the sessions as follows:

2A + 12B = 9 hours

On Thursday, we would have

5A + 3B = 9 hours

2A + 12B = 9  Eqn 1

5A + 3B = 9   Eqn 2

Multiply equation 2 by -4

2A + 12B = 9

-20A - 12B = -36

2A - 20A = 9 -36

-18A = -27

Divide both sides by -18

A = 1.5 hours

For B, substitute A in the first equation

2(1.5) + 12B = 9

Answer: 12, 30, 162

Step-by-step explanation:

b)  For a regular polygon the central angles will all add up to 360

n= number of sides = 360/30

n=12

d) For exterior angles, the sum of the exterior angles is also 360

n = number of sides = 360/12

n=30

f) for any polygon

interior ange = ((n-2)180) / n

interior angle = ((20-2)180 / 20

interior angle =  (18)(180) / 20

interior angle = 162

Answer:

b. 12

d. 30

f. 162°

Step-by-step explanation:

b. The number of sides of a regular polygon can be found by dividing 360° by the central angle.

In this case, the central angle is 30°, so the number of sides is 360° / 30° = 12.

The polygon is a dodecagon.

d. The number of sides of a regular polygon can be found by dividing 360° by the exterior angle.

In this case, the exterior angle is 12°, so the number of sides is 360° / 12° = 30.

The polygon is a triacontagon.

f. The interior angle of a regular polygon can be found by using the formula  [tex]\frac{180(n-2) }{n}[/tex]where n is the number of sides.

In this case, n=20, so the interior angle is 180(20-2) / 20 = 162°.

Step-by-step explanation:

The surface area of a triangular prism is made up of 2 congruent triangles and 3 rectangles.

The area of a triangle is half the product of its base and height.

The area of a rectangle is the product of its width and length.

Therefore, to calculate the surface area of the given triangular prism, we first need to find the length of the hypotenuse (H) of the triangular base. To do this, we can use Pythagoras Theorem:

[tex]\begin{aligned}H^2&=6^2+8^2\\H^2&=36+84\\H^2&=100\\H&=\sqrt{100}\\H&=10\; \sf yd\end{aligned}[/tex]

Therefore, the surface area of the given triangular prism is:

[tex]\begin{aligned}\textsf{Surface Area}&=2 \cdot \left(\dfrac{1}{2} \cdot 6 \cdot 8\right)+(6 \cdot 5)+(8 \cdot 5)+(10 \cdot 5)\\\\&=2 \cdot \left(24)+30+40+50\\\\&=48+30+40+50\\\\&=158\; \sf yd^2\end{aligned}[/tex]

[tex]\boxed{\begin{minipage}{4 cm}\underline{Surface area of a sphere}\\\\$SA=4 \pi r^2$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius.\\\end{minipage}}[/tex]

From the given diagram, the diameter of the sphere is 24 yd.

As the diameter is twice the radius, the radius of the sphere is r = 12.

Substitute the value of r into the formula to calculate the surface area of the sphere:

[tex]\begin{aligned}\textsf{Surface area}&=4 \pi (12)^2\\&=4 \pi (144)\\&=576\pi \; \sf yd^2\end{aligned}[/tex]

To determine the number of ways a president and vice president can be chosen from a class of 14 students using permutations, we can follow these steps:

1: Select the president:

Since we need to choose one student to be the president, we have 14 options available.

2: Select the vice president:

Once the president has been chosen, we need to select one student to be the vice president. Since the president has already been chosen, we are left with 13 remaining students to choose from.

3: Calculate the total number of ways:

To find the total number of ways, we multiply the number of choices at each step. Therefore, the total number of ways to choose a president and vice president is obtained by multiplying the number of choices in Step 1 (14) by the number of choices in Step 2 (13):

To find the number of revolutions made by a roller,

We need to calculate the distance traveled by the roller in one revolution and then divide the total distance traveled by the roller by this distance.

The distance traveled in one revolution can be calculated using the formula:

Distance = Circumference of the roller = π * Diameter

Let's calculate it:

Diameter = 1.02 m

Radius = Diameter / 2 = 1.02 / 2 = 0.51 m

Circumference = 2 * π * Radius = 2 * 3.14159 * 0.51 ≈ 3.20876 m

Now, we divide the total distance traveled by the roller (291.72 m²) by the distance traveled in one (3.20876 m) to get the number of revolutions:

Number of Revolutions = Total Distance / Distance per Revolution

Number of Revolutions = 291.72 m² / 3.20876 m ≈ 90.972 revolutions

const diameter = 1.02; // meters

const thickness = 1.3; // meters

const area = 291.72; // square meters

const radius = diameter / 2;

const circumference = 2 * Math.PI * radius;

const totalDistance = area / thickness;

const revolutions = totalDistance / circumference;

console.log("Number of revolutions:", revolutions);

Therefore, the roller will make approximately 90.972 revolutions while rolling over the surface of 291.72 m².

We find the number of revolutions a roller makes over a specific surface area by determining the area the roller covers in one revolution and dividing the total surface area by this figure. We treat the roller as a cylinder unrolling onto a plane and calculate the rectangle’s area that is formed.

To find the number of revolutions a roller makes when rolling over a specified surface area, we first need to find the area that the roller covers in one revolution. This can be obtained by imagining the roller as a cylinder 'unrolling' its outer curved surface onto the plane it's moving on. That unrolled surface forms a rectangle, whose area is equivalent to the circumference of the roller (which gives the length of the rectangle) multiplied by the thickness of the roller (which gives the width of the rectangle).

The circumference of the roller is given by the formula 2πr, where r is the radius, i.e., half of the diameter of 1.02m. That equates to 1.62m. The thickness of the roller, provided as 1.3m, serves as the width of the rectangle. So, the area covered in one revolution is 1.62m * 1.3m.

Dividing the total surface area covered, 291.72m², by the area covered in one revolution provides the number of revolutions the roller made.

Given sinz = -4/5 for pi < z < (3pi)/2, we need to find the value of cosz. We can use the trigonometric identity of Pythagorean theorem to find the value of cosz.

According to Pythagorean theorem, sin2θ + cos2θ = 1, where θ is the angle in the right-angled triangle and sin, cos are the trigonometric ratios.

The negative sign for the given sinz indicates that the angle z is in the third quadrant. So, we can take the help of the unit circle to find the value of cosz as shown below:

Here, we have used the Pythagorean identity of sin2z + cos2z = 1 on the unit circle to find the value of cosz. Since the value of sinz is already given, we can find the value of sin2z as: sin2z = sinz x sinz = (-4/5) x (-4/5) = 16/25

Then, we can substitute the value of sin2z in the Pythagorean identity as: cos2z = 1 - sin2z = 1 - (16/25) = 9/25We need to find the value of cosz.

So, we can take the square root of cos2z as: cosz = ±(√(9/25)) = ±(3/5)The sign of cosz can be determined by considering the quadrant of the angle z.

Since the angle z is in the third quadrant, the value of cosz is negative. Hence, cosz = -3/5.So, the value of cosz is -3/5.
