The population grow by 24.7% between the years 2004 and 2009

from the question, we have the following parameters that can be used in our computation:

Population in 2004 = 2122

Population in 2009 = 2647

The growth of the population between the years is calculated as

Percentage = Population in 2009/Population in 2004  - 1

Substitute the known values in the above equation, so, we have the following representation

Percentage = 2647/2122 - 1

Evaluate

Percentage = 24.7%

Hence, the population grow between the years by 24.7%

The value of the side BC is equal to 10√21 in the simplest rationalized form using the trigonometric ratio of tangent.

The trigonometric ratios is concerned with the relationship of an angle of a right-angled triangle to ratios of two side lengths.

The basic trigonometric ratios includes;

sine, cosine and tangent.

Considering the tangent of angle 60°

tan 60° = BC/(10√7) {opposite/adjacent}

BC = 10√7 × tan 60° {cross multiplication}

BC = 10√7 × √3 {tan 60 = √3}

BC = 10√21

Answer:

Let's start by figuring out how many aliens are captured every four hours. If half of the aliens are captured every four hours, that means the number of remaining aliens is also halved every four hours. So we can use exponential decay to model the number of aliens remaining after t four-hour periods:

N(t) = N₀ (1/2)^t

where N₀ is the initial number of aliens and t is the number of four-hour periods that have passed.

The initial number of aliens is 1,300, and we want to know how many remain after 14 four-hour periods (from 2:00am to 8:00pm, a total of 16 hours with 4-hour intervals):

N(14) = 1,300 (1/2)^14

N(14) ≈ 20.16

So there will be approximately 20 aliens remaining free at 8:00pm on Wednesday. Note that the actual number may be slightly different due to rounding, and also because we assumed that the capture rate remains constant throughout the 16-hour period.

The time needed before the doctor administers the medication again is given as follows:

d) 22.2 hours.

The exponential function giving the amount of the medicine in the patient's bloodstream after t hours is given as follows:

[tex]A(t) = 500(0.93)^t[/tex]

The medication will be applied when the amount is given as follows:

A(t) = 100.

Hence the time needed is obtained solving the exponential function as follows:

[tex]100 = 500(0.93)^t[/tex]

[tex](0.93)^t = \frac{100}{500}[/tex]

[tex](0.93)^t = 0.2[/tex]

The logarithm of base 10 is the inverse of the exponential, hence:

[tex]t = \frac{\log{0.2}}{\log{0.93}}[/tex]

t = 22.2 hours.

Of the $8,400 in sales, the store donated about 8% to hospitals.

To find the percentage of $8,400 that was donated to hospitals, we can set up a proportion using the given information.

Let's represent the percentage of the sales donated as x.

We can set up the proportion:

(x/100) = 672/8400

To solve for x, we can cross-multiply and then divide:

8400 * x = 672 * 100

8400x = 67200

x = 67200 / 8400

x = 8

Therefore, the store donated approximately 8% of $8,400 to hospitals.

Answer:

y = - 3x + 7

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 7) and (x₂, y₂ ) = (2, 1) ← 2 points on the line

m = [tex]\frac{1-7}{2-0}[/tex] = [tex]\frac{-6}{2}[/tex] = - 3

the line crosses the y- axis at (0, 7 ) ⇒ c = 7

y = - 3x + 7 ← equation of line

The equation of the line in fully simplified slope-intercept form is y = -2.8x + 7

The linear graph represents the given parameter

For the graph, we have the points

(0, 7) and (25, 0)

A linear equation is represented as

y = mx + c

Where

c = y when x = 0

So, we have

y = mx + 7

Using the point (2.5, 0) on y = mx + 7, we have

m(2.5) + 7 = 0

2.5m + 7 = 0

Evaluate

m = -2.8

So, we have

y = -2.8x + 7

Hence, the equation of the line in fully simplified slope-intercept form is y = -2.8x + 7

The probability that a randomly chosen person from this group has type B is 0.4.

The probability of type AB is 0.12, and the probability of type B or type AB is 0.52.

We have,

The probability that a randomly chosen person from this group has type B is given by the number of people with blood type B divided by the total number of people in the group:

Probability of type B

= Number of people with type B / Total number of people

In this case, the number of people with blood type B is 20, and the total number of people is 50 (22 + 20 + 6 + 2).

Probability of type B = 20 / 50 = 0.4

Similarly, the probability that a randomly chosen person from this group has type AB is given by the number of people with blood type AB divided by the total number of people:

Probability of type AB = Number of people with type AB / Total number of people

In this case, the number of people with blood type AB is 6, and the total number of people is 50. Therefore,

Probability of type AB = 6 / 50 = 0.12

To find the probability that a randomly chosen person from this group has blood type B or type AB, we need to add the probabilities of both events:

Probability of type B or type AB = Probability of type B + Probability of type AB

Probability of type B or type AB = 0.4 + 0.12 = 0.52

Thus,

The probability that a randomly chosen person from this group has type B is 0.4, the probability of type AB is 0.12, and the probability of type B or type AB is 0.52.

The difference between 1/5 and 2/10 is that they are different representations of the same value.

The ratio is a comparison of two quantities while proportional reasoning involves finding an equivalent ratio.

"Fifth" can refer to the ordinal number of a position or the unit fraction 1/5.

The diagram can be used to illustrate fraction concepts.

1/5 is simple, but 2/10 can be reduced to 1/5 by dividing both numbers by 2. They are both 0.2 or 20%. 1/5 and 2/10 are different fractions with different purposes.

Use 1/5 for 5 parts and 1/5 (simplified from 2/10) for 10 parts. 1/5 and 2/10 = 0.2, ratio reasoning emphasizes ratios between quantities. A 2:3 boys-to-girls ratio compares the constant ratio between changing quantities.

Proportional reasoning maintains constant ratios between quantities, while ratio reasoning uses fractions or ratios to compare relationships. For instance, if distance doubles, so does speed.

Step 3/5: "Fifth" is the ordinal number for the object five places away in a sequence. See diagram. The fifth circle is 1/5 of a whole in unit fraction sequence. Imagine a rectangle divided into five equal parts, each shaded to show 1/5. Shaded part = 1/5 of whole.

x = 4.5 cm

Therefore, the width of the paper is 4.5 cm and the length is 5 times the width which is 22.5 cm

In Mathematics and Geometry, the slope of any straight line can be determined by using the following mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = rise/run

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

By substituting the given data points into the formula for the slope of a line, we have the following;

Slope (m) = 2/1

Slope (m) = 2.

Based on the table, the slope is the change in y-axis with respect to the x-axis and for Shonda it is equal to 2/1 or 2. Therefore, Shonda would finish before Corine because 2/1 > 3/2.

The question is incomplete and the complete question is shown in the attached picture.

The maximum value of z = 4x + 4y, subject to the given constraints, is 92/3, which occurs when x = 14/3 and y = 4.

To maximize the objective function z = 4x + 4y subject to the given constraints, we can solve this linear programming problem using the graphical method.

First, let's graph the feasible region determined by the constraints:

1. Graph the line 2x + 4y = 28:

  Rewrite the equation in slope-intercept form: y = -0.5x + 7

  Plot two points on the line: (0, 7) and (14, 0), and draw a line through them.

2. Graph the line 5x + 6y = 50:

  Rewrite the equation in slope-intercept form: y = (-5/6)x + (25/3)

  Plot two points on the line: (0, 25/3) and (10, 5/3), and draw a line through them.

3. Shade the region that satisfies the constraints:

  Shade the region below the line 2x + 4y ≤ 28.

  Shade the region below the line 5x + 6y ≤ 50.

  The feasible region is the intersection of the shaded regions.

Next, we evaluate the objective function at the corner points of the feasible region to determine the maximum value.

The corner points of the feasible region are:

A: (0, 7)

B: (0, 25/6)

C: (14/3, 4)

D: (10, 5/3)

Evaluate the objective function at each corner point:

z(A) = 4(0) + 4(7) = 28

z(B) = 4(0) + 4(25/6) = 50/3

z(C) = 4(14/3) + 4(4) = 92/3

z(D) = 4(10) + 4(5/3) = 140/3

The maximum value of z is obtained at z(C) = 92/3.

Therefore, the maximum value of z = 4x + 4y, subject to the given constraints, is 92/3, which occurs when x = 14/3 and y = 4.
