Answer:

C. Side = 17cm, 12 cm, 7 cm

Step-by-step explanation:

This question is based on the Triangle Inequality Theorem. This states that the sum of the 2 smaller sides will always be greater than the third. One important thing to note is that the sum cannot be equal to the third side, it must be greater than. We can tell that the third answer, as listed above, is correct because 12+7=19. Since 19 is greater than 17, these sides lengths will create a triangle.

As mentioned early, the 2nd answer cannot be correct because 9+7=16. Since 16=16, these lengths cannot create a triangle.

Step-by-step explanation:

The radius of the smaller cone created when a horizontal plane passes through the cone at exactly 4 feet from the base is 6.6 feet.

To determine the radius of the smaller cone created when a horizontal plane passes through the cone at exactly 4 feet from the base, we can use similar triangles.

The given cone has a height of 10 feet and a diameter of 22 feet. The radius of the given cone is half of the diameter, so it is 22/2 = 11 feet.

When a horizontal plane passes through the cone at exactly 4 feet from the base, it divides the cone into two parts: the smaller cone and the frustum (the remaining part of the cone).

The height of the smaller cone is the distance from the 4-feet mark to the top of the cone, which is 10 - 4 = 6 feet.

Since the two cones are similar, their corresponding dimensions are proportional. The ratio of the corresponding heights is the same as the ratio of the corresponding radii.

So, we can set up the following proportion:

(r_small / r_given) = (h_small / h_given)

Substituting the values we have:

(r_small / 11) = (6 / 10)

Cross-multiplying:

10 * r_small = 11 * 6

r_small = (11 * 6) / 10

r_small = 66 / 10

r_small = 6.6 feet

Therefore, the radius of the smaller cone created when a horizontal plane passes through the cone at exactly 4 feet from the base is 6.6 feet.

The answer of the given question based on the greatest value is One such number is 3,043,728.

A number system is a system of representing and expressing numbers in a clear, concise, and organized way. The most commonly used number system is the decimal system, which is based on the numbers 0 through 9. However, there are many other number systems, including binary, octal, hexadecimal, and more.

Each number system has a set of rules and conventions for representing numbers. For example, in the decimal system, each digit can represent a value from 0 to 9, and the position of each digit determines its value.

The digit 3 in 143,728 has a value of 3 x 1000 = 3000. To find a number in which the digit 3 has a value that is 10 times as great as this, we need to find a number in which the digit 3 has a value of 10 x 3000 = 30,000.

One such number is 3,043,728. In this number, the digit 3 appears in the hundred thousands place, which means its value is 3 x 100,000 = 300,000. This is indeed 10 times as great as the value of the digit 3 in 143,728.

A number's face value is the digit itself, while its place value is determined by its placement.

In order to answer the question, we must determine which of the following integers has a value for the digit 3 that is 10 times greater:

If we pay close attention, we can see that the number 137 has a third digit in its tens place while the number 143 has a third digit in its unit place. Additionally, there are 398,389,392, which has a digit 3 and is ten times bigger than the number 137.

These numbers will be written as follows if we now express their location and value in words:

143 = 1 × 100 + 4 × 10 + 3 × 1.

137 = 1 × 100 + 3 × 10 + 7 × 1.

The value of 'a' that makes the given system a dependent system is 4.

To make the given system a dependent system, we need to find the value of 'a' that makes both equations equivalent or proportional.

Let's begin by rearranging the first equation so that it is in the standard form y = (2/3)x.

Now, let's substitute this expression for y in the second equation and simplify:

6y - a - 4x = 0

6(2/3)x - a - 4x = 0

4x - a = 0

We can see that if we choose 'a' to be equal to 4, then both equations will be equivalent. In other words, the system will become a dependent system with infinitely many solutions.

To see why, let's substitute 'a' as 4:

6y - 4 - 4x = 0

6y - 4x = 4

Now, if we compare this equation to the first one we wrote, y = (2/3)x, we can see that they are equivalent. Thus, any solution that satisfies the first equation will also satisfy the second equation, and vice versa. This means that we have infinitely many solutions to the system.

In conclusion, the value of 'a' that makes the given system a dependent system is 4.

Answer:

6 is not a solution to the given equation.

Step-by-step explanation:

We are given the equation \(x^2-4=5x\)

We need to know whether or not x=6 is a solution. This means that we should substitute in 6 for each instance of x. Then, if both sides of the equation are equal, then 6 is a solution to the equation.

\(x^2-4=5x\\\\(6)^2-4=5(6)\\\\36-4=30\\\\32=30\)

As 32 ≠ 30, 6 is not a solution to the given equation.

Answer:

Step-by-step explanation:

You want to know the values of x, y, and z, which are three angles in a figure showing two triangles that share a side and a base.

The angle sum theorem tells you the sum of angles in a triangle is 180°. This means ...

  x° +32° +46° = 180°

  x = 180 -78 . . . . . . divide by °, subtract 78 from both sides

  x  = 102

Adjacent angles that form a straight line are called a "linear pair." Their sum is 180°

  y° +x° = 180°

  y = 180 -x = 180 -102

  y = 78

You may have noticed that the value of y is equal to the sum of the two given angles in the triangle containing x. That is, the exterior angle is equal to the sum of the remote interior angles. This is also true for the left-side triangle:

  x° = z° +36°

  z = x -36 . . . . . divide by °, subtract 36

  z = 102 -36

  z = 66

__

Additional comment

The theorems cited here can be used in a number of different combinations to find the measures of these angles. We could start by finding y = 32+46 = 78, then z = 180 -36 -78 = 66, and x = 36 +66 = 102.

The solution is:

A. (–8, 2), is the solution to the system of equations y=1/2x+6 and

y=3/4x-4

Here, we have,

(1)       y =  ½x + 6  

(2)       y = -¾x –  4     Set (1) = (2)  

½x +   6 = -¾x –  4     Multiply each side by 4

2x  + 24 = -3x – 16     Add 16 to each side

2x  + 40 = -3x              Subtract 2x from each side  

       40 = -5x              Divide each side by -5

(3)       x = -8                 Substitute (2) into (1)

         y = ½(-8)  +6

            = -4 + 6

            =  2

The solution to the system of equations is (-8 ,2).

You can see the graphs of the two functions in the figure below. The two lines intersect at (-8, 2).

Check:

2 = ½(-8) + 6     2 = -¾(-8) - 4

2 = -4 +6           2 = 6 - 4

2 = 2                 2 = 2

The distance traveled by the race car along the circular track is given as follows:

4.33 feet.

Before obtaining the distance traveled by the car, we need to obtain the circumference of the circle.

The circumference of a circle of radius r is given by the multiplication of 2π and r, as follows:

C = 2πr.

The radius for the circle in this problem is of:

r = 2.7 feet.

Then the circumference of the circle is of:

C = 2π x 2.7 = 17 feet.

(replacing r by it's numeric value).

The entire circumference is equivalent to 2π radians. The car traveled 1.6 radians, hence the distance traveled is given as follows:

Distance = 1.6/2π x 17 = 4.33 feet.

The solution to system (a) = [-4 5y/3] and the solution to system (b) = [6 2y -8].

Therefore, Solution to system (a) = Solution to system (b): [-4 5y/3] = [6 2y -8]

Given the following two systems,(a) 1-2 - Ay (2x + 7y 3 -3(b) 1-2-4y = 2 122 + 7 = 14 Here, we need to find the inverse of the common coefficient matrix of the two systems and then solve the two systems using the inverse by evaluating AB where A represents the coefficient matrix of (a) and (b) represents the coefficient matrix of (b).

Common coefficient matrix of the two systems, A = 1 -2-7y2 3

Here, we need to find the inverse of A.

The inverse of A is given by,A-1 = 1/3 [3 -2 -7y-2 1 2y]The right-hand sides of the system (a) and (b) are given by, For system (a), B1 = -3For system (b), B2 = [12 2].

Therefore, the solutions to the two systems by using the inverse are given by, For system (a), X1 = A-1B1 = 1/3 [3 -2 -7y-2 1 2y] [-3]= [-4 5y/3]

For system (b), X2 = A-1B2 = 1/3 [3 -2 -7y-2 1 2y] [12 2]T= [ 6 2y -8].

Thus, the solution to system (a) = [-4 5y/3] and the solution to system (b) = [6 2y -8].

Therefore, Solution to system (a) = Solution to system (b): [-4 5y/3] = [6 2y -8]
