At the beginning of a population study, city had 210,000 people. Each year since, the population has grown by 5.5%. Let t be the number of years since the start of the study. Let y be the cities population. Write an exponential function showing the relationship between y and t.

Y=

Answers

Answer:

y = 210,000(1.055)^t

Step-by-step explanation:

Initial population: p = 210,000

Annual growth rate: 5.5% = 0.055

Number of years: t

Population in year t: y

y = p(1 + r)^t

y = 210,000(1 + 0.055)^t

y = 210,000(1.055)^t

THANK YOU.

The greatest common factor of 14x and 18xy is 2x if the numbers are 14x and 18xy.

What is LCM?

It is defined as the common number of two integers, which is the lowest number that is a multiple of two or more numbers. The full name of LCM is the least common multiple.

It is given that:

The GCF of 14x and 18xy

As we know, GCF is the greatest common factor.

The greatest common factor of 14 and 18 or

GCF(14, 18) = 2

And the greatest common factor of GCF of x and xy

= x

the greatest common factor of 14x and 18xy is:

= 2x

Thus, the greatest common factor of 14x and 18xy is 2x if the numbers are 14x and 18xy.

HELP

Answers

Answer:

Y = 1

X= -1

Step-by-step explanation:

Y is 3 so x is 2 and if y = x then x - 1 would be one and then that would make y = 1

X is 2 - y which is 3 will equal -1

Answer:

Step-by-step explanation:

2x – 3y = -5.........(i)

у = х – 1................(ii)

Multiply equation (ii) by 3,

3у = 3х – 3.......(iii)

Add (i) and (iii)

2x – 3y = -5

-3x + 3y = – 3

-x = -8

x = 8

put the value of x in eq (ii)

у = х – 1

у = 8 – 1

y = 7

The graph of y = f(x) is shown below. What are all of the real solutions of f(x) = 0?

Answers

Answer:

x = -4, 4

Step-by-step explanation:

Given graph in the attachment represents the function y = f(x)

Real solutions of the function means all the points where the curve of the graph either touches or crosses the x-axis.

Since, graph of the function touches and crosses at x = -4 and x = 4

Therefore, all real solutions of the function are x = -4 and x = 4

Jack and beth are selling wrapping paper for a school fundraiser. Customers can buy rolls of plain wrapping paper and rolls of shiny wrapping paper. Jack sold 5 rolls of plain and 8 rolls of shiny for a total of $190. Beth sold of 5 rolls plain and 3 shiny for a total of $90. Find the cost of each roll of wrapping paper

Answers

Answer:

Cost of a roll of plain wrapping paper = $6

Cost of a roll of shiny wrapping paper = $20

Step-by-step explanation:

Let [tex]x[/tex] denotes cost of a roll of plain wrapping paper and [tex]y[/tex] denotes cost of roll of shiny wrapping paper.

Jack sold 5 rolls of plain and 8 rolls of shiny for a total of $190.

[tex]5x+8y=190\,\,\,(i)[/tex]

Beth sold of 5 rolls plain and 3 shiny for a total of $90.

[tex]5x+3y=90\,\,\,(ii)[/tex]

Subtract (ii) from (i).

[tex]8y-3y=190-90\\5y=100\\y=20[/tex]

Put [tex]y=20[/tex] in (ii)

[tex]5x+3(20)=90\\5x+60=90\\5x=90-60\\5x=30\\x=6[/tex]

Therefore,

Cost of a roll of plain wrapping paper = $6

Cost of a roll of shiny wrapping paper = $20

Electric Field HockeyIn this activity, you will again explore the relationship between an electric field and charged particles in the field, but this time youll have a gaming challenge. To begin, open Electric Field Hockey.Directions:On the control bar, make sure that the Puck is Positive and the Field boxes are checked. Also, make sure that the Practice option is selected.Your aim is to score goals by manipulating the black puck (test charge) into the blue-colored bracket (goal) on the right. Think smart and place positive source charges (red) and negative source charges (blue) in such a way that the black puck moves into the goal.Note that when you place a red, positive source charge in the hockey field, a red arrow appears on the black puck (test charge) showing the force the positive charge exerts on the puck. Similarly, when you place a blue, negative source charge in the hockey field, a blue arrow appears on the black puck (test charge) showing the force the negative charge exerts on the puck.Question 1Part APlace a red charge on the hockey field and click Play. In which direction do electric field lines point? In which direction does the black puck move? What conclusion do you draw from this movement?Part BClick Reset and then click Clear. Now, place a blue charge in the hockey field and click Play. In which direction do electric field lines point? In which direction does the black puck move? What conclusion do you draw from this movement?Part CManipulate the mass of the puck by dragging the mass bar to the right to increase the mass and to the left to decrease it. What changes do you see in the speed of the puck? Which principle works behind this change?Part DIn the same situation, what do you observe about the relationship between the speed of the black puck and its distance from the blue charge?Question 2You can make the puck travel in complex ways by placing a set of charges around on the field. So, heres your game challenge: Arrange sources charge around to propel the puck from its starting position into the goal. Thats pretty easy for a straight shot; you just put a negative charge behind the goal. But what if there are barriers along the way? This is a real test of your physical understanding, including Newtons laws of motion and electrostatic forces. Games on!Part AOn the control bar, check the Trace and Field boxes. The game has three Difficulty levels. Start with Difficulty level one and arrange source charges to get the puck into the goal. Once youve made a score at any level, increase the Difficulty level. Take a screen capture of two of your most difficult goals and paste them here. At least one of these should be at Difficulty level 2 or 3.Please Answer Questions with complete sentences.
