The equation most closely models the line of best fit for the scatter plot is y = 2.5x

<h3>Equation of a line</h3>

A line is the distance between two points. The equation of a line in point-slope form is given as y =mx + b

  • m is the slope
  • b is the intercept


Using the coordinate points on the line (3, 5000) and (9, 20000)

Get the slope

Slope = 20000-5000/9-3
Slope = 15000/6 = 2500

Determine the y-intercept

5000 = 2500(3) + b

b = 5000 - 7500
b = -2500

Determine the equation

y = 2.5x - 2.5

Hence the equation most closely models the line of best fit for the scatter plot is y = 2.5x

The formula Upper A equals 23.1 e Superscript 0.0152 tA=23.1e0.0152t models the population of a US​ state, A, in​ millions, t ye
Wewaii [24]

Answer:

a) A(t=0)= 23.1 e^{0.0152(0)}=23.1e^0 =23.1

b) t = \frac{ln(\frac{28.3}{23.1})}{0.0152}=13.357 years

So for this case the answer would be 13.347 years, the population will be 28.3 million and ye year would be 2000+13.347 and that would be approximately in 2014

Step-by-step explanation:

For this case we assume the following model:

A(t)= 23.1 e^{0.0152 t}

Where t is the number of years after 2000/

Part a

For this case we want the population for 2000 and on this case the value of t=0 since we have 0 years after 2000. If we rpelace into the model we got:

A(t=0)= 23.1 e^{0.0152(0)}=23.1e^0 =23.1

So then the initial population at year 2000 is 23.1 million of people.

Part b

For this case we want to find the time t whn the population is 28.3 million.

So we need to solve this equation:

28.3= 23.1 e^{0.0152(t)}

We can divide both sides by 23.1 and we got:

\frac{28.3}{23.1}= e^{0.0152t}

Now we can apply natural log on both sides and we got:

ln(\frac{28.3}{23.1})= 0.0152 t

And then for t we got:

t = \frac{ln(\frac{28.3}{23.1})}{0.0152}=13.357 years

So for this case the answer would be 13.347 years, the population will be 28.3 million and ye year would be 2000+13.347 and that would be approximately in 2014

A rectangle is 5 feet wide and 10 feet long what is the perimeter
lara31 [8.8K]
The perimeter would be 30 feet.
Since the rectangle is 10 ft long and 5 ft wide, you have to all sides together
10 + 10 + 5 + 5 = 30

PLEASE HELP 100 POINTS!!
tresset_1 [31]

y = x^2 + 5x -3

y-x =2

Replace y in the second equation with the first one:

x^2 + 5x -3 - x = 2

Simplify by combining like terms:

x^2 + 4x -3 = 2

Subtract 2 from both sides:

x^2 + 4x -5 = 0

Fctor the polynomial:

(x-1) (x+5) = 0

Solve for both X's:

x = 1 and x = -5

Now replace x in the second equation with both value and solve for y:

y -1 =2, y = 3

y - -5 =2, y +5 = 2, y = -3

Now combine the sets of answers:

(1,3) and (-5,-3)
