Answer 1

Answer:

17

Step-by-step explanation:

2 (4) + 6^2 / 4 = 8 + 36 / 4 = 8 + 9 = 17.

When solving these types of problems, make sure to use BEDMAS. For example, in this question, do x^2 / 4 before 2y + (x^2 / 4).

Step-by-step explanation:

Noah is driving to a concert and needs to pay for parking. There is an automatic fee of $8 just to enter the parking lot, and when he leaves the lot, he will have to pay an additional $2 for every hour he had his car in the lot. How much total money would Noah have to pay for parking if he left his car in the lot for 3 hours? How much would Noah have to pay if he left his car in the lot for tt hours?

Answers

he would have to pay $14

The total charge for 3 hours of parking is $14 and for t hours it is given as 8 + 2t.

How to solve a linear equation?

A linear equation can be solved by equating the LHS and RHS of the equation following some basic rules such as by adding or subtracting the same numbers on both sides and similarly, doing division and multiplication with the same numbers.

The automatic fee of parking is given as $8.

And, the charge for per hour parking is $2.

Suppose the number of hours the car is parked be x.

Then, the equation for the cost of parking for 3 hours is given as,

Automatic charge  + 2 × per hour charge

⇒ 8 + 2 × 3 = $14

And, for t hou5rs the parking charge will be 8 + 2t.

Hence, the required charges for the parking are given as $14 and 8 + 2t respectively.

please please help me i can’t figure this out .. ernest's friend rolls a six-sided number cube and lands on square 8. She asks Ernest to guess what number she rolled. He guesses that she rolled a 3. She says he's wrong.

ernest wonders if she could have rolled a number other than 3. Use a mapping diagram to help guess what number she rolled.

If she would have rolled


Create a Mapping Diagram

When playing this game, the square you land on during the first turn depends on the number you roll. You can write this as a function: SQUARE(number), or S(n). For example, if you roll a 2, you end up on square 2 (when you land on 3 you move back a space). So S(2) = 2.




1. Describe the possible inputs of S(n) using words. (2 points: 1 point for the description, 1 point for the list of numbers)








2. Describe the possible outputs of S(n) using words. (1 point)






3. Draw a mapping diagram for S(n) that maps all the possible inputs and outputs for a player's first turn. Note that the player should begin on square 1. (6 points: 3 points for the inputs and outputs, and 3 points for the mapping)
















4. In the mapping diagram you created, what numbers are in the domain of S(n)? Explain what this means. (2 points: 1 point for the domain, 1 point for the explanation)








5. What numbers are in the range of S(n)? Explain what this means. (2 points: 1 point for the range, 1 point for the explanation)









Evaluate the Conjecture

6. Based on the mapping diagram, is it possible that the player rolled a number other than 3 to land on square 8? If so, which number or numbers? Explain your answer. (2 points: 1 point for the answer, and 1 point for the explanation)









Defining Functions
7. Does the mapping diagram you created for S(n) for the first turn of the game represent a function? Why or why not? (2 points: 1 point for the answer, and 1 point for the explanation)

Answers

Answer:

1. The values of the dice. It can be 1,2,3,4,5,6.

2. Values in which you don’t move on the map. 2,5,6,11,14,15

3. inputs: 1,2,3,4,5,6

outputs: 2,2,8,5,6,8

4. Domain numbers are 1,2,3,4,5,6.

5. Range numbers are 2,2,8,5,6,8.

6.) The player could have rolled a 3 or a 6. Based on the chart, if they rolled a three they could land on a 8 and if they rolled a 6 they would have to move up a space.

7. The mapping diagram does represent a function because it tells how the numbers depend on each other.

Write two polynomial functions whose quotient will be the same degree as the divisor?

Answers

Answer:

[tex]f(x) = 15x^2 -14x - 8[/tex]

[tex]g(x) = 5x + 2[/tex]

Step-by-step explanation:

Represent the two polynomials with f(x) and g(x)

The question requires that we assume values for f(x) and g(x) as long as the condition in the question is met;

Let

[tex]f(x) = 15x^2 -14x - 8[/tex]

[tex]g(x) = 5x + 2[/tex]

To determine if the condition is met, we need to divide f(x) by g(x)

[tex]\frac{f(x)}{g(x)} = \frac{15x^2 -14x - 8}{5x + 2}[/tex]

Factorize the numerator

[tex]\frac{f(x)}{g(x)} = \frac{15x^2 - 20x + 6x - 8}{5x + 2}[/tex]

[tex]\frac{f(x)}{g(x)} = \frac{(5x + 2)(3x - 4)}{5x + 2}[/tex]

Cross out 5x + 2

[tex]\frac{f(x)}{g(x)} = 3x - 4[/tex]

The result is referred to as quotient, Q

[tex]Q = 3x - 4[/tex]

Note that Q and g(x) have the same degree of 1

The LCD is (y - p)^y

NOTE : (y - p)^y /  (y - p)^y-2 = (y - p)^(y - (y - 2)) = (y - p)^2

Δ UWV and Δ UWX are similar triangles , thus corresponding angles are congruent , that is

∠ UWV = ∠ UWX , substitute values

9z - 24 = z ( subtract z from both sides )

8z - 24 = 0 ( add 24 to both sides )

8z = 24 ( divide both sides by 8 )

The diagram is a straightedge and compass construction. A is the center of one circle, and B is the center of the other.

Explain why segments AC, CB, BD, and AD are all the same length.

Answers

You could use Pythagoras Theorem to solve this.

All the points are equidistant from the centre of line AB, therefore it is just the same triangle but rotated. I hope this help but I can show you on paper if you don’t understand that answer :)

All the segments AC, CB, BD, and AD are same in length because all are radiuses of the circles which have same dimensions.

What is a radius?

Radius is the distance between circle center point and the point at its circumference.

In the given problem,

AC and AD are clearly the radiuses of the circle whose center is at point A (say first circle). Therefore these must be equal in length.

AC = AD

Similarly, BC and BD are the radiuses of the circle whose center is at point B (say second circle) . Therefore these are also equal in length.

BC = BD

Now you can observe that the first circle has a radius AB also which is equal to the radius of second circle i.e., BA.

∴ Both the circles has same radius length.

and

∴AC = AD = CB = BD

Hence all the segments which are nothing but the radiuses of both the circles must be equal.

Student's Work
Student's Answer
A. t = 0.55m + 12; $21.90
B. t = 12m +0.55; $21.90
C. t = 0.55 + m + 12 $30.55
D. t = 0.55(12) + m; $24.60

Answers

Answer: The answer would be A : t=0.55m+12;$21.90

The equation that models the situation, using m to represent the number of miles traveled and t to represent the total cost for the trip is A. t = 0.55m + 12; and the total cost of an 18 mile trip is $21.90.

⇒ The correct answer is A. t = 0.55m + 12; $21.90

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

Cost of pick up = $12

Additional fee = $0.55 per mile

Now if,m represent the number of miles traveled and t to represent the total cost for the trip

Thus, Total additional fee = 0.55m

Total cost for the trip =  Total additional fee + Cost of pick up

⇒ t = 12 + 0.55m

This is the equation that models the situation.

Now  the total cost of an 18 mile trip, put m = 18 in the equation we get,

⇒ t = 12 + 0.55*18

⇒ t = 12 + 9.9

⇒ t = 21.9

Thus,the total cost of an 18 mile trip is $21.90.

The equation that models the situation, using m to represent the number of miles traveled and t to represent the total cost for the trip is A. t = 0.55m + 12; and the total cost of an 18 mile trip is $21.90.

Thus  the correct answer is A. t = 0.55m + 12; $21.90

m<B=2x+50

8x+14=2x+50

So you want to get x alone so subtract 2x from each side.

6x+14=50

Since the variable is not alone you will also need to subtract 14 from both sides.

6x=36

You will need to divide both sides by 6
