Answer: The y-intercept of the exponential function is <u>approximately 2000 less than </u>the y-intercept of the linear function.

Step-by-step explanation:

Given: The exponential function in the table represents the student population of the county that Greenville is in, in years since 2010.

The standard exponential function is given by :-

y=Ab^x, where A is the initial population and x is the number of years.

From table , the multiplicative rate of change b=\frac{y_3}{y_2}=\frac{4400}{2200}=2

Put x=2 and b=2 in the equation, we get

2200=A(2)^2\\\Rightarrow\ A=\frac{2200}{4}=1950

We know that the value of y intercept occurs when x=0,

From the given table , the y intercept of exponential function (Initial population)= 550

The linear function in the graph shows the population of Greenville in the years since 2010.

From the given graph, the y intercept of linear function  (x=0 for year 2010)= 2500

The difference in y intercepts = 2500-550=1950\approx2000....\text{{Rounded nearest thousand}}

Hence, The y-intercept of the exponential function is <u>approximately 2000 less than </u>the y-intercept of the linear function.

James folds a piece of paper in half several times,each time unfolding the paper to count how many equal parts he sees. After fo
Snezhnost [94]

Answer:

There will be total 2048 parts of the given paper if James if able to fold the paper eleven times.

The needed function is y = 2 ^n

Step-by-step explanation:

Let us assume the piece of paper James decides to fold is a SQUARE.

Now, let us assume:

n : the number of times the paper is folded.

y : The number of parts obtained after folds.

Now, if the paper if folded ONCE ⇒  n = 1

Also, when the pap er is folded once, the parts obtained are TWO equal parts.

⇒  for n = 1 , y = 2       ..... (1)

Similarly, if the paper if folded TWICE  ⇒  n = 2

Also, when the paper is folded twice, the parts obtained are FOUR equal parts.

⇒  for n = 2 , y = 4       ..... (2)

⇒y  = 2^2  =  2^n

Continuing the same way, if the paper is folded SEVEN times  ⇒  n = 7

So, y = 2^ n = 2^7 = 128

⇒  There are total 128 equal parts.

Lastly,  if the paper is folded ELEVEN  times  ⇒  n = 11

So, y = 2^ n = 2^{11} = 2048

⇒  There are total 2048 equal parts.

Hence, there will be total 2048 parts of the given paper if James if able to fold the paper eleven times.

And the needed function is y = 2 ^n

Rewrite the equation below so that it does not have fractions.
Leviafan [203]

9514 1404 393

Answer:

  8x -24 = 9y

Step-by-step explanation:

We assume your equation is ...

  2/3x -2 = 3/4y

__

Fractions can be eliminated by multiplying the equation by the least common denominator of the fractions.

  LCM(3, 4) = 12

Multiplying the equation by 12 gives you ...

  12(2/3x -2) = 12(3/4y)

  8x -24 = 9y

Find the vaues of x and y
Leni [432]

x=76

y=4

I think that answer should be right. Since it is isosceles the base angles will be the same and the top angle is an angle bisector which means that the angle split on top has even splits. Since no other side lengths- or any lengths at that matter- are give, it is safe to assume that y=4.
