Answer:

25.12 m (or 25.13 m)

Step-by-step explanation:

Recall the formula for the circumference of a circle:

\(2\pi r\)

where r is the radius.

We are given that the radius is 4 m, so let's plug that into our formula:

\(2\pi r=\\2\pi *4=\\8\pi\)

\(\pi\) is approximately 3.14, so let's multiply 8 m by 3.14. We get:

25.12

So, the circumference is about 25.12 m.

(if you multiply by pi itself using a calculator, the answer is about 25.13 m)

Hence, the value of s must be 35 units so that the quadrilateral becomes a parallelogram.

Answer:

Answer:

1 speaker is $91.48

3 speakers = $91.48 × 3

= $274.44

1 tire is 9$2.55

5 tires = $92.55 × 5

= $462.75

8, 100 bills = $800

The cost for the 3 speakers and 5 tires = $274.44 + $462.75

= $737.19

Therefore, the change that Jason got was = $800 - $737.19

The volume of the pyramid  equals the one-third of the volume of the rectangular prism which is: 13 units³.

The volume of a rectangular prism is calculated as: V = (length)(width)(height).

The volume of a pyramid is calculated as one-third of the product of its height, width, and length. Thus, the formula is given as: volume = 1/3(length)(width)(height)..

If the height, width, and length of a pyramid are the same as the height, width, and length of a rectangular prism, then:

Volume of Pyramid = 1/3(volume of rectangular prism)

Volume of Pyramid = 1/3(length)(width)(height).

Given the following:

Dimensions of the pyramid and the rectangular prism are the same.

Volume of the rectangular prism = 39 units³.

Therefore, since the volume of pyramid = 1/3(volume of rectangular prism), we would have the following:

The volume of the pyramid = 1/3(39)

The volume of the pyramid = 13 units³

Therefore, the volume of the pyramid  equals the one-third of the volume of the rectangular prism which is: 13 units³.

Answer:

The circle's circumference is approximately 106.81 centimeters.

Explanation:

The formula for the circumference of a circle is C = 2πr, where C is the circumference, π is pi (approximately 3.14), and r is the radius of the circle.

So, for a circle with a radius of 17 centimeters, its circumference can be found by:

C = 2πr

C = 2 x 3.14 x 17

C ≈ 106.81 cm

Therefore, the circumference of the circle is approximately 106.81 centimeters.

a. The system of inequalities for this situation can be represented as:

x (number of snacks) ≥ 0

y (number of bottles of water) ≥ 0

2x + 2.25y ≤ 70 (total amount of money remaining)

y ≤ 4 (maximum number of bottles of water that can be carried on a tray)

7x + 7y ≤ 70 (total cost of tickets and snacks/drinks cannot exceed the amount given)

b. To graph the system, we can start by plotting the inequality 2x + 2.25y ≤ 70. This represents all the points that satisfy the inequality and forms a boundary line for the feasible region. The line will be a boundary line because it is less than or equal to 70.

We can plot the inequality y ≤ 4 as a horizontal line at y = 4. This represents the maximum number of bottles of water that can be carried.

Finally, we can plot the inequality 7x + 7y ≤ 70 as a boundary line. This represents the total cost of tickets and snacks/drinks that cannot exceed the amount given.

The feasible region will be the area between these lines, above the x-axis and y-axis, and below the line y=4.

The vertices of this feasible region will be the intersection points of the three lines, which are (10,0), (0,10) and (8,4)

c. The combinations of snacks and drinks that are possible are the ones that fall within the feasible region. Any point within the feasible region represents a valid solution in this context, because it satisfies all the constraints and is within the budget.

d. Every point within the feasible region represents a valid solution in this context, because it satisfies all the constraints and is within the budget.

e. One possible combination is (8,4) which is 8 snacks and 4 bottles of water, this combination is possible because it's within the feasible region and satisfies all the constraints. One combination that is not possible is (12,3), it's not possible because it's not within the feasible region and doesn't satisfy the constraint y ≤ 4.

f. To prove that the combination (8,4) is possible, we substitute these values into the system of inequalities:

2(8) + 2.25(4) = 35 ≤ 70 (total amount of money remaining)

4 ≤ 4 (maximum number of bottles of water that can be carried)

7(8) + 7(4) = 56 ≤ 70 (total cost of tickets and snacks/drinks cannot exceed the amount given)

To prove that the combination (12,3) is not possible, we substitute these values into the system of inequalities:

2(12) + 2.25(3) = 30.5 > 70 (total amount of money remaining)

3 > 4 (maximum number of bottles of water that can be carried)

7(12) + 7(3) = 63 > 70 (total cost of tickets and snacks/drinks cannot exceed the amount given)

As all the inequalities are not satisfied, the combination (12,3) is not possible.

A system of inequalities is a set of two or more inequalities that must be satisfied simultaneously. It is a way to represent a set of constraints using mathematical equations. These constraints can be related to a problem in a specific area, such as finance, engineering, or operations research. The solution set of a system of inequalities is the common set of solutions that satisfy all the inequalities in the system. The solutions can be represented graphically as a region in a coordinate plane called the feasible region, which is the set of all possible solutions.

The value of a in the equation is 4

The quadratic equation is given as

g(x) = ax² - 12x + 9

Start by differentiating the equation

So, we have the following representation

g'(x) = 2ax - 12

Next, we set the differentiated equation to 0

So, we have

2ax - 12 = 0

Divide through by 2

ax = 6

Make a, the subject

a = 6/x

The graph intersect the x-axis at the vertex

The graph that correctly shows the boundary line for y ≤ 2x − 4, is B. Graph B.

The inequality y ≤ 2x − 4, shows that the y - intercept is - 4. What this means is that the boundary line must pass through ( 0, - 4 ). As Graphs C and D do not cross ( 0, - 4 ), neither of them can be the boundary line.

Also, when representing an inequality on a graph, the signs of ≤ and ≥ are presented with a solid line. > and < are the ones presented with a broken line. This means that Graph A cannot the boundary line for the inequality.

\(Additional = \$30\) (weekly)

Required

Determine the initial value

The initial value is the amount he has in its bank account before making his weekly savings.

From the question, we have that his initial balance is $78.

Hence, the initial value is $78

However, his weekly balance can be expressed as:

\(Balance = Base\ Amount + Additional * number\ of weeks\)

Represent number of weeks with x; So, we have:

\(Balance = 78 + 30 * x\)

\(Balance = 78 + 30 x\)

5th term of the sequence is -4

To find the 5th term in the sequence, we need to substitute n =  5 into the expression given

 \(a_5\) =  26- 6( 5)  

\(a_5\) =  26- 30

\(a_5\) = -4  

The formula given, an =  26- 6n, represents an  computation sequence with a common difference of-6.

This means that each term in the sequence is  attained by obtain 6 from the  former term.  

It's important to note that the formula is written in general form, meaning that it can be used to find any term in the sequence by simply plugging in the  matching value of  n.

The graphs of f(x) = -10x-1 and g(x) = \(2^{x}\). A new function h(x) by reflecting f(x) over the x-axis thus the graphs of h(x) and g(x) intersect twice.

To reflect f(x) over the x-axis,  simply change the sign of the function

h(x) = -f(x) = -(-10x-1) = 10x+1

Now we have the functions g(x) = \(2^{x}\) and h(x) = 10x+1. To find where these functions intersect, we can set them equal to each other and solve for x

10x + 1 = \(2^{x}\)

We can't solve this equation algebraically, so we'll need to use numerical methods. One way to do this is to graph the two functions and look for their intersection points.

Here is a table of values for g(x) and h(x) at several x-values

x g(x) h(x)

-2 1/4 -19

-1 1/2 -9

0 1 1

1 2 11

2 4 21

From the table, we can see that the graphs intersect twice, once between x = -2 and x = -1, and again between x = 1 and x = 2.

Therefore, the graphs of h(x) and g(x) intersect twice.
