The formula for exponential growth is expressed as

y = a(1 + r)^t

where

y is the population after t years

ais the initial population

r is the growth rate

t is the number of years

From the information given,

a = 350

r = 14% = 14/100 = 0.14

By substituting these values into the equation, the function to model th growth rate is

y = 350(1 + 0.14)^t

y = 350(1.14)^t

We would substitute values of t into the equation to determine corresponding values of y. We have

For t = 2, y = 350(1.14)^2 = 454.86

For t = 6, y = 350(1.14)^6 = 768.24

For t = 10, y = 350(1.14)^10 = 1297.52

We would plot these values of y on the y axis and the corresponding values of t on the x axis. The graph is shown below

The time when the population will reach 20000 would be the value of x at the point where y = 20000 on the graph. It is around y = 30.87

Thus, the population will reach 20000 in approximately 31 years

We can confirm this by solving the equation. We have

20000 = 350(1.14)^t

20000/350 = 1.14^t

57.14 = 1.14^t

Taking natural log of both sides, we have

ln 57.14 = ln1.14^t = tln1.14

t = ln 57.14/ln1.14

t = 30.87505

Answer:

3/4 inches

Explanation:

The most number of cross symbols (vertical line) is on the length 6/8 inches, that is, 3/4 inches.

So, the most common button is of length 3/4 inches.

The predicted temperature of the substance after 3.5 minutes implies that x =3.5, and we are to find y.

Therefore,

Therefore, the predicted temperature of the substance, 3.5 minutes after the start of the experiment is 40.5 degrees Celsius

Equation is -(x+4)² +4.

A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line. The vertex form of a quadratic equation is y = a (x h) 2 + k as opposed to the regular quadratic form, which is an x 2 + b x + c = y. In both cases, the variables that indicate whether the parabola is facing up (+ a) or down ( a) are y, the y-coordinate, x, and a.

Given Data

Solutions (-6, 0) and (-2,0)

y = a(x - (-6)) (x-(-2))

y  = a(x+6) (x+2)

Vertex (-4,4)

at x = -4 and y = 4

4 = a(-4+6)(-4+2)

4 = a (2)(-2)

a = -1

y = -1(x+6)(x+2)

y = -(x²+8x+12)

y = =(x² + 3x +4x+4²-4²+12)

y = -(x+4)² +4

Equation is -(x+4)² +4.

Step-by-step explanation:

The polygon EFGH is a polygon.

What is polygon?

A polygon is a form of planar figure in geometry and is defined as a closed polygonal chain made up of a finite number of straight line segments. A region that is enclosed by a bounding plane, a bounding circuit, or both is referred to as a polygon. The portions of a polygonal circuit are referred to as its edges or sides.

To check the polygon EFGH is a square or not, first to find the length of each side of polygon.

If the length of each side is equal then the polygon EFGH is a square.

(Since length of each side of square is equal).

We know,

[tex]d \sqrt{(x_2-x_1)^2 + (y_2 - y_1)^2}[/tex]

where,

d = distance

[tex](x_1, x_2)[/tex] = Coordinates of the first point.

[tex](x_2, y_2)[/tex] = Coordinates of the second point.

So,

[tex]EF = \sqrt{(3-(-2))^2 + (3.5-3.5)^2} = \sqrt{25 + 0} = 5[/tex]

[tex]FG = \sqrt{(3-3)^2 + (-1.5-3.5)^2 } = \sqrt{0 + 25} = 5[/tex]

[tex]GH = \sqrt{(-2-3)^2 + (-1.5-(-1.5))^2} = \sqrt{25 + 0} = 5[/tex]

[tex]EH = \sqrt{(-2-(-2))^2 + (-1.5-3.5)^2} = \sqrt{0 + 25} = 5[/tex]

From above the length of each side is equal.

Therefore, given polygon EFGH is a square.

ANSWERS

(a) 0.420

(b) 0.400

(c) With a large number of spins, there might be a difference between the experimental and theoretical probabilities, but the difference should be small

EXPLANATION

(a) The experimental probability is given by,

In this case, Donna spun the dial 1000 times and 420 times it landed on yellow,

Hence, the experimental probability of landing on yellow is 0.420.

(b) The theoretical probability is given by the geometry of the spinner and, if it is fair, the number of yellow sections,

In this case, the spinner is divided into 10 equally sized slices, and 4 of them are yellow,

Hence, the theoretical probability of landing on yellow is 0.400.

(c) As we can see in parts a and b, for 1000 trials, the experimental and theoretical probabilities are almost the same - i.e. there is a small difference. This is known as the law of large numbers which states that if the number of trials of an experiment is large, the experimental probability of each event should be close to the theoretical probability.

Hence, the true statement is the first one: with a large number of spins, there might be a difference between the experimental and theoretical probabilities, but the difference should be small.

if she bikes 2/3km in 4 minutes how much kilometers she bike on 1 minute?

we solv using cross multiplication

we multiply 1 and 2/3 and the divide by 4

she will bike 1/6km in one minute

The problem can be expressed in the following system of linear equations:

A total of 120 adults (a) and students (s) attended a school:

a + s = 120

Each adult paid $2.50, mathematically, that is 2.5a

Each student paid $1, mathematically, that is 1s

and the total paid by adults and students attending the game was $189

then, we have:

2.5a + 1s = 189

then, we can conclude that the problem can be expressed as follows:

a + s = 120

2.5a + 1s = 189

or equivalently:

a + s = 120

2.5a + s = 189

The question is since f(x) really means y, then when y = 9 what's x?

Solution

y = 2x - 4

y = 9

9 = 2x - 4                Add 4 to both sides

9+4 = 2x                 Combine

13 = 2x                    Divide both sides by 2

13/2 = 2x/2              

6.5 = x

Do you mean what is f(X) when x is 3. f(3) = 2x - 4. So what is y when x = 3

y = 2x - 4                   Substitute 3 for x

y = 2*3 - 4                  Combine

y = 6 - 4

y = 2
