Hey! I need help with these 2 questions! Thanks.

The population of rabbits in the year 2013 is 1186.

To predict the population of rabbits in the year 2013, we can use exponential growth. The formula for exponential growth is:

P = P₀ * e^(rt)

where:

P = final population

P₀ = initial population (950)

r = the growth rate (we need to find this)

t = time elapsed (13 years)

We can use the data from 2003 to find the growth rate:

1000 = 950 * e^(r * 3)

1000 = 950 * e^(3r)

1000/950 = e^(3r)

ln (1000/950) = 3r

r = (ln(1000 / 950)) / 3

r = 0.0171

Now that we have the growth rate, we can use it to find the population in 2013:

P = 950 * e^(0.0171 * 13)

P = 1186

What is a circle theorem?

The circle theorem is a set of mathematical rules and relationships that apply to circles and their components, such as chords, tangents, and angles. These theorems describe how the different parts of a circle relate to each other and are used to solve geometric problems involving circles. Some common circle theorems include the inscribed angle theorem, the chord-chord theorem, and the tangent-secant theorem.

By using the circle theorem, we can write

5x-7 = 119

5x = 119 + 7

5x = 126

x = 126/5

x = 25.2°

Hence, the measure of the angle x would be 25.2°.

For given linear equations, 27hx -9y = -18 and y = 1 - 6x

h will be 2.

What is a linear equation, exactly?

When the greatest power of a variable is 1, the equation is said to be linear. Another term for it is a one-degree equation. The standard form of a linear equation with one variable is Ax + B = 0. There are three variables in this equation: x, A, and B. A denotes a coefficient. A linear equation with only two variables is commonly written as Ax + By = C. There are three more constants in addition to the constant C: the variables x and y, the coefficients A and B, and the variables.

Now,

As general equation of a line is y=mx + c where m=slope and c=constant

and here given lines are  27hx -9y = -18 and y = 1 - 6x

transforming these into general equations

y=-3hx+2 where m=-3h

and y=-6x+1    where m=-6

Now As slope of parallel lines is equal

therefore, -3h=-6

h=6/3

h=2

Hence,

           h will be 2.

According to the population growth law, the size of a population grows exponentially over time, with a growth rate proportional to population size. If the population doubling time is t, then the population size P can be written as:

[tex]P = P_0 * 2^{t/t_d)}[/tex]

where P_0 is the initial population size, t is the time elapsed, and t_d is the doubling time.

To find the time it will take for the population to increase to 3 times its original population size, we can set [tex]P = 3P_0[/tex] and solve for t:

[tex]3P_0 = P_0 * 2^{t/t_d}[/tex]

Dividing both sides by [tex]P_0[/tex] gives:

[tex]3 = 2^{t/t_d}[/tex]

Taking the logarithm of both sides (using any base) gives:

[tex]log(3) = log(2^{t/t_d} )[/tex]

Using the logarithmic identity

[tex]log(a^b) = b*log(a),[/tex]

we can rewrite this as:

[tex]log(3) = (t/t_d)*log(2)[/tex]

Solving for t, we get:

[tex]t = t_d * (log(3)/log(2))[/tex]

Substituting [tex]t_d[/tex] = 6 hours (given in the problem), we get:

[tex]t = 6 * (log(3)/log(2)) hours[/tex]

Simplifying using the change of base formula

[tex](log(a)/log(b) = log_b(a))[/tex], we get:

[tex]t = 6 * log_2(3)[/tex] hours

Therefore, the answer is (f) None of the above.

A different type of quadrilateral known as parallelogram has both pairs of its opposite sides parallel and equal.

The figure shows a parallelogram ABCD with the parameters AB II CD and AD II BC. Furthermore, AB = CD and AD = BC.

In a parallelogram, the opponent angles are equal.. So it means that side /A is equal to side /C, let's equate the two angles and solve for x;

5y - 3 = x + 3y

2y - x = 3                            ........(1)

Also, consecutive angles of a parallelogram are supplementary,

therefore,

/C + /D = 180

x + 3y + 2x = 180

3x + 3y = 180

x + y = 60                                  .......(2)

Now, add equations (1) and (2)

(2y-x) + (y+x) = 3 + 60

3y = 63

y = 21

now put this value of y in (2) we get,

x + y = 60

x + 21 = 60

x = 39

Answer:

the equation 2 - 8 + 33 = 0 can be factored as 27 = 0, which is a verified answer

Step-by-step explanation:

To factor the equation 2 - 8 + 33 = 0, we start by collecting all the terms on one side of the equation:

2 - 8 + 33 = 0

becomes

33 - 8 + 2 = 0

Next, we can rewrite this as:

33 - 6 = 0

Finally, we factor the left-hand side of the equation to get:

33 - 6 = (33 - 3) - 3 = 30 - 3 = 27 - 0

So the factored form of the equation 2 - 8 + 33 = 0 is 27 = 0.

Verification: We can verify that the factored form of the equation is correct by substituting 0 for 27 and checking that the equation holds. So, if we replace 0 for 27 in equation 27 = 0, we get:

27 = 0, which is true.

Therefore, the equation 2 - 8 + 33 = 0 can be factored as 27 = 0, which is a verified answer.

Shaniece is expected to select a lime chew about 505 times in the next 1200 selections.

Based on the given results, Shaniece selected a lime chew 24 times out of 57 selections. To estimate the expected number of times she would select a lime chew in the next 1200 selections, we can use the proportion of lime chews selected in the first 57 selections:

The proportion of lime chews selected = 24/57

To estimate the expected number of lime chews in the next 1200 selections, we can multiply the proportion by the total number of selections:

expected number of lime chews in the next 1200 selections = (24/57) x 1200

The expected number of lime chews in the next 1200 selections = 505.263

Rounding to the nearest whole number, we would expect Shaniece to select a lime chew about 505 times in the next 1200 selections.

The original price of the table was $200 before the 64% discount was applied.

What is the percentage?

Percentage is a way of expressing a fraction or proportion out of 100. It is commonly used to compare two quantities, indicate the change or growth of a quantity over time, or express the probability or chance of an event occurring.

If you received a 64% discount on the sale price of a table, and the sale price is $72, we can calculate the original price of the table as follows:

Determine the percentage of the original price that corresponds to the sale price after the discount:

If the sale price is 100% - 64% = 36% of the original price, after the 64% discount.

Use the percentage found in step 1 to calculate the original price:

Let x be the original price

x * 36% = $72

0.36x = $72

x = $72 / 0.36

x = $200

Therefore, the original price of the table was $200 before the 64% discount was applied.

Answer:

  see below for a graph

  (-8, 4) is in the solution set

Step-by-step explanation:

You want the graph and a solution point for the inequalities y ≤ -6/5x -4 and y ≥ 2/5x +4.

The solid boundary line of the first inequality will cross the y-axis at -4, and will have a "rise" of -6 units for each "run" of 5 units. Shading is below this boundary line.

The solid boundary line of the second inequality will cross the y-axis at +4 and will have a "rise" of 2 units for each "run" of 5 units. Shading is above this boundary line.

The boundary lines make an X shape on the graph, crossing at the point (-5, 2). The solution set is in the left quadrant.

Point (-5, 2) is in the solution set, as are points in the doubly-shaded space to its left. (-8, 4) is one of those.

__

Additional comment

The boundary lines are solid because the "or equal to" case is included in each.

The ≤ symbol tells you y-values that satisfy the first inequality will be less than (or equal to) those on the boundary line.

The ≥ symbol tells you y-values that satisfy the second inequality will be greater than (or equal to) those on the boundary line.

At the end, Ann saves a total amount of 3 dollars according to the money she spent and on allowance according to the percentages.

The required proportionality relationship between Jordan and his friend for the sit-up is y = 2x.

Proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

Here,
Jordan recorded the number of sit-ups he completed during the first 4 track practices, we can establish the proportionality relationship between Jordan and his friend by comparing the number of sit-ups each completed during each practice.

Let's call the number of sit-ups that Jordan and his friend completed during each practice "x" and "y". Then, the number of sit-ups that his friend completed during each practice would be "2x".

The proportionality relationship between Jordan and his friend can be expressed as,

y = 2x

This means that for every 1 sit-up that Jordan completed, his friend completed 2 sit-ups, or that Jordan's friend completed twice the number of sit-ups that Jordan completed during each practice.
