The length of the missing side is 3√17 ft. Option B is the correct option.

What is the hypotenuse?

The longest side of a right-angled triangle, or the side opposite the right angle, is known as the hypotenuse in geometry. The Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides, can be used to determine the length of the hypotenuse.

The △ABC is a right-angled triangle.

Thus the sum of squares of the legs of the triangle is equal to the square of the hypotenuse.

The hypotenue is 13 ft.

Assume that the missing leg is equal to x.

The legs of the triangle are x and 4ft.

Apply Pythagorean theorem:

13² = 4² + x²

x² = 169 -16

x² = 157

x = √(3×3×17)

x = 3 √17

A right pyramid with an equilateral triangular base has a lateral face with a surface area of 75 square meters. The side of the base of a slant with a height of 30 meters is 5 meters long.

Let’s call the side length of the equilateral triangular base “s”. We know that the area of one lateral face is 75 square meters, and that face is a triangle with base s and height 30 meters (the slant height). We can use the formula for the area of a triangle to solve for s:

Area = (1/2) * base * height

75 = (1/2) * s * 30

Simplifying the equation, we get:

75 = 15s

s = 75/15

s = 5

Therefore, the length of the side of the equilateral triangular base is 5 meters.

Anderson traveled 15 mph to go to the restaurant and 12 mph to get home. Anderson went at 15 mph for 3 hours and at 12 mph for 6 hours. if the entire trip took 9 hours.

    The given speed Anderson, the total time taken, and asked to find the time traveled at each speed:

         Speed, [tex]S_1[/tex] = 15 mph

         Speed, [tex]S_2[/tex] = 12 mph

         Total time, [tex]t[/tex] = 9 hours

         Time traveled with speed 1,

         [tex]t_1[/tex] Time traveled with speed 2, [tex]t_2[/tex]

To solve the given problem, let's use the following formula:

         Total   [tex]t[/tex] (time) = [tex]t_1[/tex] ( time 1) + [tex]t_2[/tex] (time 2)

   Now, time 1 can be represented as

          [tex]t_1[/tex] (time 1) = [tex]d[/tex] (distance) /  [tex]S_1[/tex] (speed 1)

Similarly, time 2 can be represented as:

           [tex]t_2[/tex] (time 2) = [tex]d[/tex] (distance) /  [tex]S_2[/tex] (speed 2)

 Here, we need to find the time traveled at each speed. Let's use these equations to solve the given problem.

      Time traveled with speed 1, [tex]t_1[/tex]  = [tex]d[/tex] /  [tex]S_1[/tex]

      Time traveled with speed 2,  [tex]t_2[/tex] = [tex]d[/tex] /  [tex]S_2[/tex]

As we know the total time, we can find the value of d in terms of [tex]t[/tex].

        So, [tex]d[/tex] =  [tex]S_1[/tex] * [tex]t_1[/tex]  =  [tex]S_2[/tex]  *  [tex]t_2[/tex]

     From the above equation, we can write: [tex]t_1[/tex]  /  [tex]t_2[/tex] =  [tex]S_2[/tex]  /  [tex]S_1[/tex] [tex]t_2[/tex]

                                                                                    =  [tex]t[/tex]  - [tex]t_1[/tex]

     Substitute the value of  [tex]t_2[/tex]  in equation(1):

           [tex]t_1[/tex]  / ([tex]t[/tex] - [tex]t_1[/tex] ) =  [tex]S_2[/tex]  / [tex]S_1[/tex][tex]t_1[/tex]  [tex]S_1[/tex]

Step-by-step explanation:

The experimental probability that Roberto will get a hit during his next time at bat is 0.25 or 25%.

The experimental probability of an event is calculated by dividing the number of times the event occurred by the total number of trials.

In this case, the event is "getting a hit" and the number of times it occurred is 11. The total number of trials is 44, which represents the number of times Roberto was at bat.

Experimental probability of getting a hit = Number of times Roberto got a hit / Total number of times at bat

Experimental probability of getting a hit = 11 / 44

Experimental probability of getting a hit = 0.25 or 25%

Therefore, the experimental probability that Roberto will get a hit during his next time at bat is 0.25 or 25%.

The missing numbers to complete the linear equation that gives the rule for this table are y = 11x-10

A linear equation is an equation that describes a line in a two-dimensional coordinate system. It can be written in the form:

y = mx + b

where y and x are variables representing coordinates on the vertical and horizontal axes, respectively, m is the slope of the line, and b is the y-intercept (the point where the line crosses the y-axis).

The slope of the line represents the rate of change between y and x, or the steepness of the line. A positive slope indicates that the line is increasing from left to right, while a negative slope indicates that the line is decreasing from left to right. A slope of zero indicates a horizontal line, while a slope that is undefined (such as when x is constant) indicates a vertical line.

To find the equation that gives the rule for this table, we need to determine the slope and y-intercept of the line that passes through these points.

We can start by using the two given points (4, 34) and (5, 45) to find the slope:

slope = (change in y) / (change in x)

slope = (45 - 34) / (5 - 4)

slope = 11

Now we can use the point-slope form of a linear equation to write the equation for this line, using the point (4, 34):

y - 34 = 11(x - 4)

Simplifying this equation gives:

y = 11x - 10

To find the value of the ratio b/a for the 3.0 kg ball and the 1.0 kg ball placed at opposite ends of a massless beam in equilibrium, we can use the principle of moments.

Solution:

Step 1: Identify the forces and distances involved. The 3.0 kg ball has a force of 3.0g (g represents gravity) acting at distance a from the pivot point. The 1.0 kg ball has a force of 1.0g acting at distance b from the pivot point.

Step 2: Apply the principle of moments. For the system to be in equilibrium, the clockwise moment and anticlockwise moment must be equal. This means that the product of the force and distance for each ball must be equal:

3.0g × a = 1.0g × b

Step 3: Solve for the ratio b/a. First, divide both sides of the equation by g:

3.0a = 1.0b

Now, divide both sides of the equation by 3.0a:

b/a = 1/3

There is no solution if the boundary conditions are inconsistent, i.e., if y(0) ≠ y(L) = 1.

We are given the boundary-value problem:

y" + 16y = 0, y(0) = 1, y(L) = 1

The characteristic equation is r^2 + 16 = 0, which has roots r = ±4i.

The general solution to the differential equation is then y(x) = c1cos(4x) + c2sin(4x).

Using the boundary conditions, we get:

y(0) = c1 = 1

y(L) = c1cos(4L) + c2sin(4L) = 1

Substituting c1 = 1 into the second equation, we get:

cos(4L) + c2*sin(4L) = 1

Solving for c2, we get:

c2 = (1 - cos(4L))/sin(4L)

Thus, the general solution to the differential equation that satisfies the given boundary conditions is:

y(x) = cos(4x) + (1 - cos(4L))/sin(4L)*sin(4x)

Now, we can answer the questions:

(a) To have precisely one nontrivial solution, we need the coefficients c1 and c2 to be uniquely determined. From the above expression for c2, we see that this is only possible if sin(4L) is nonzero. Thus, if sin(4L) ≠ 0, there exists precisely one nontrivial solution.

(b) If sin(4L) = 0, then c2 is undefined and we have a family of solutions that differ by a constant multiple of sin(4x). Hence, there are infinitely many solutions.

(c) There is no solution if the boundary conditions are inconsistent, i.e., if y(0) ≠ y(L) = 1.

The probability of the repair person taking 3 or more hours to fix the machine is 0.3, or 30%.

As an AI language model, I do not have the specific information needed to answer this question. However, we can use probability theory to solve this problem.

Let's assume that the probability of repairing the machine in 2 hours or less is p, and the probability of taking more than 2 hours is q (which is the same as saying the probability of taking 3 or more hours).

We know that p + q = 1, meaning that the sum of the probabilities of repairing in 2 hours or less and taking more than 2 hours is equal to 1, which represents the total probability.

Now, if we know the value of p, we can easily calculate q by subtracting it from 1:

q = 1 - p

For example, if we assume that the probability of repairing in 2 hours or less is 0.7, then the probability of taking more than 2 hours is:

q = 1 - 0.7 = 0.3

So, in this case, the probability of the repair person taking 3 or more hours to fix the machine is 0.3, or 30%.

However, without knowing the specific probabilities of the repair person finishing within 2 hours or the probabilities of taking longer, we cannot provide an accurate answer to this question.

Using the stars and bars technique, Candice can distribute her 24 pieces of candy among her four siblings in 2,925 different ways. If she must give each sibling at least one of each type of candy, there are 67,200 ways to distribute the candy among the four siblings.

(A) To solve this problem, we can use the technique of stars and bars. We have a total of 24 pieces of candy to share among four children. We can represent this using 24 stars, with 3 bars to separate the stars into four groups, one for each child. For example, the following arrangement represents giving 6 pieces of candy to the first child, 10 pieces to the second child, 3 pieces to the third child, and 5 pieces to the fourth child:

*****|**********|***|****

The number of ways to arrange the stars and bars is equal to the number of ways to choose 3 positions out of the 27 possible positions for the stars and bars. Therefore, the number of different ways that Candice can share her candy with her three younger brothers is:

C(27, 3) = 27! / (3! * 24!) = 2925

(B) Now, we need to ensure that each child receives at least one Tootsie roll and one Twizzler. We can give each child one of each candy to start, and then distribute the remaining 13 Tootsie rolls and 7 Twizzlers using the stars and bars technique. We have 13 Tootsie rolls and 7 Twizzlers to distribute among four children, which can be represented using 13 stars and 3 bars for the Tootsie rolls, and 7 stars and 3 bars for the Twizzlers. The number of ways to arrange the stars and bars for each type of candy is:

C(16, 3) = 560 for the Tootsie rolls

C(10, 3) = 120 for the Twizzlers

To find the total number of ways to distribute the candy, we can multiply the number of ways for each type of candy:

560 * 120 = 67200

Therefore, there are 67,200 different ways for Candice to share her candy with her three younger brothers after her mother asks her to give at least one of each type of candies to each of her brothers.

[tex]A * (x1, x2, x3) = (3x3, x3, -x2 - 3x1)[/tex]
The matrix A can be found by comparing the components of the vectors:
A = | 0  -3   0 |
     | 0   0   1 |
     |-3  -1   3 |
So, the matrix A of the linear transformation from R3 to R3 given by T(x) = v × x is:
A = | 0  -3   0 |
     | 0   0   1 |
     |-3  -1   3 |
