Answer: Circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle and π is a constant.

We know that the diameter is twice the radius (d = 2r).

So when we increase the circumference of the circle from 12π cm to 18π cm, we are increasing the radius from r to r'.

To find the increase in diameter, we can use the formula for the diameter, and subtract the original diameter from the new diameter.

d' = 2r' and d = 2r

d' - d = 2r' - 2r

We know that the relationship between circumference and radius is C = 2πr.

So we can write:

12π = 2πr and 18π = 2πr'

r = 6/π and r' = 9/π

then

d' - d = 2r' - 2r = 2(9/π) - 2(6/π) = 18/π - 12/π = 6/π

Therefore, the diameter must increase by 6/π cm in order to increase the circumference of the circle from 12π cm to 18π cm.

Answer:

To verify that [n+3]! / n! = (n+1), we can use the definition of factorial:

[n+3]! = (n+3) * (n+2) * (n+1) * n!

And we can cancel out n! from both sides of the equation:

(n+3) * (n+2) * (n+1) = n+1

Which is true, and thus [n+3]! / n! = (n+1) holds true.

Another way to verify this is by simplifying the RHS and LHS

(n+1) = (n+1)

And the LHS,

(n+3)! = (n+3)(n+2)(n+1)n! = (n+1)(n+2)(n+3)n! = (n+1)(n+2)(n+3)!/n!

which is also equal to (n+1)

So, [n+3]! / n! = (n+1) is true.

Answer:

To find out how many groups of riders there will be, we need to divide the total number of people waiting in line (157) by the maximum number of people allowed on the ride at one time (17).

157 people / 17 people/group = 9.235 groups (approx)

But since the groups must be in whole numbers, we have to round up the value 9.235 groups to the next whole number, which is 10 groups.

So, the number of groups of riders will be 10.

Answer: 9 groups of riders.

Step-by-step explanation:

To find out how many groups of riders there will be, you need to divide the total number of people waiting in line by the maximum number of people allowed on the ride at one time.

157 (total people in line) ÷ 17 (people allowed per ride) = 9.235 (groups of riders)

Because you can't have a fraction of a group, you need to round down to get the whole number of groups.

So the answer is 9 groups of riders.

Step-by-step explanation:

Step-by-step explanation:

A function assigns the value of each element of one set to the other specific element of another set. The value of the function when the value of x is -4 is 92.

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.

Given that F(x)=3x²-10x+4, therefore, the value of the function can be calculated by substituting the value of x as -4.

Therefore, the value of the function when the value of x is -4  can be calculated as shown below,

F(x) = 3x² - 10x + 4

F(-4) = 3(-4)² - 10(-4) + 4

= 3(16)  + 40 + 4

= 48 + 40 + 4

= 92

Hence, the value of the function when the value of x is -4 is 92.

Answer: a. The sum of two numbers is always greater than zero.

Step-by-step explanation:

A counterexample to this conjecture would be when the two numbers are both negative. For example, the sum of -5 and -3 is -8, which is less than zero.

b. The sum of a positive number and a negative number is always positive.

A counterexample to this conjecture would be when the negative number is greater than the positive number. For example, the sum of 5 and -6 is -1, which is less than zero.

c. If a figure has four sides, then it is a rectangle.

A counterexample to this conjecture would be a square. A square has four sides, but it is not a rectangle because all of its angles are 90 degrees while a rectangle has four right angles.

It's good to keep in mind that a conjecture is a statement that is made based on observations and that it hasn't been proven yet, therefore a counterexample can be used to show that the conjecture is false.

Answer:

a)  -5 + 1 = -4

b)  2 + (-10) = -8

c)  A scalene trapezium.

Step-by-step explanation:

A counterexample is proof that a conjecture is false.

Given conjecture:

If one of the numbers is negative, and its absolute value is equal to or greater than the value of the positive number, the result will always be equal to or less than zero.

Counterexample:

As -4 is less than zero, this proves that the conjecture is false.

Given conjecture:

If the absolute value of the negative number is greater than the value of the positive number, the result will always be negative.

Counterexample:

As -8 is negative, this proves that the conjecture is false.

Given conjecture:

Counterexample:

The interior angles of a rectangle are congruent (90°).

A scalene trapezium has four sides, but as its interior angles are all different, it is not a rectangle.  This proves that the conjecture is false.

The coordinates of the remaining vertices exists (2√(13),1) and (-2, 4√(13)).

A group of values that exhibit precise positioning The first number on a graph represents the distance along, while the second number represents the distance up or down.

To find the coordinates of the remaining vertices of square ABCD, we can use the information given about diagonal AC and the properties of a square. Since a square has equal side lengths and right angles, we know that the distance between opposite vertices on a diagonal must be equal to the side length of the square.

Given the coordinates of vertex A and C, we can use the distance formula to find the length of AC :

Let the equation be Distance [tex]$d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$[/tex] substitute the values in the above equation, we get

[tex]$\mathrm{AC}=\sqrt{\left((2-(-2))^2+(4-1)^2\right)}$$[/tex]

simplifying the equation, we get

[tex]$A C=\sqrt{ }(4+9)=\sqrt{ }(13)$$[/tex]

We can utilize the knowledge of the square's side length to determine the locations of the remaining vertices. Vertex B is known to have the same y-coordinate as vertex A, while vertex C is two units to the left in terms of the x-coordinate. Therefore, the coordinates of vertex B exists (-2 + 2√(13), 1).

Similar to vertex A, vertex D is known to have an identical x-coordinate, but its y-coordinate is four units below vertex C. Therefore, the coordinates of vertex D exists (-2, 4√(13))

Therefore, the coordinates of the remaining vertices exists (2√(13),1) and (-2, 4√(13)) respectively.

Answer:

Step-by-step explanation:

The car must travel a distance of 130.7 meters. This can be determined by using the equation for distance travelled with a constant acceleration:

Distance = Initial Velocity x Time + (1/2) x Acceleration x Time^2

In this case, the initial velocity is 18.1m/s, the acceleration is 3.7m/s^2, and the final velocity is 29.7m/s. We can set the final velocity equal to the initial velocity and solve for time:

29.7m/s = 18.1m/s + 3.7m/s^2 x Time

Time = 5.4 seconds

We can then plug this value for time into the equation for distance:

Distance = 18.1m/s x 5.4s + (1/2) x 3.7m/s^2 x 5.4s^2

Distance = 130.7 meters

Answer: To find the coordinates of the remaining vertices of square ABCD, we can use the information we have been given about the diagonal AC and its vertices. The diagonal AC has been given as having the vertices A(-4, -1) and C(2, 5). Since a square has right angles, we know that the other two vertices of the square must form a right angle with the diagonal AC.

To find the coordinates of vertex B, we know that it must have the same y-coordinate as vertex A, but a different x-coordinate. Since the x-coordinate of vertex A is -4, we can deduce that the x-coordinate of vertex B must be the same as the x-coordinate of vertex C, which is 2. Therefore, the coordinates of vertex B are (2, -1).

To find the coordinates of vertex D, we know that it must have the same x-coordinate as vertex A, but a different y-coordinate. Since the y-coordinate of vertex A is -1, we can deduce that the y-coordinate of vertex D must be the same as the y-coordinate of vertex C, which is 5. Therefore, the coordinates of vertex D are (-4, 5).

In summary, the coordinates of the remaining vertices of square ABCD are B(2, -1) and D(-4, 5)

Answer:

The lace is 36 cm long and 1 cm = 10 mm. So, 36 cm = 360 mm.

He can cut the lace into 18 mm pieces, so he can cut 360 mm / 18 mm = 20 pieces of 18 mm lace from the 36 cm lace.

well, there are 28 + 28 + 24 = 80 pieces total, or namely that's the 100%, and we know that 24 of those are chocolates

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 80 & 100\\ 24& x \end{array} \implies \cfrac{80}{24}~~=~~\cfrac{100}{x} \\\\\\ \cfrac{ 10 }{ 3 } ~~=~~ \cfrac{ 100 }{ x }\implies 10x=300\implies x=\cfrac{300}{10}\implies x=30[/tex]

To figure out what percentage of the trail mix is chocolate, we add up all the pieces, divide the number of chocolate pieces by the total and multiply by 100. In this case, we find that 35% of the trail mix is chocolate.

In order to figure out the percent of chocolate pieces in Caitlyn's trail mix, we first need to determine the total number of pieces. Caitlyn counts 28 raisins, 28 chocolate pieces, and 24 peanuts, which gives us a total of 80 pieces in the mix. Then, since there are 28 chocolate pieces, we divide 28 (chocolate pieces) by 80 (total pieces). This will give us the decimal representation of the portion of the mix that is chocolate. To convert this into a percentage, we multiply by 100. Hence, the calculation will be (28/80)*100 = 35%. So, 35% of the trail mix is chocolate.
