Use the model below to estimate the average annual growth rate of a certain country’s population for 1950, 1988, and 2010, where x is the number of years after 1900.

y= -0.0000081x^3+0.00267x^2+8.231

Answers

The growth rates in 1950, 1988 and 2010 are 13.9%, 23.4 and 29.8% respectively

How to estimate the country's population?

The function of the growth rate equation is given as:

y = -0.0000081x^3+0.00267x^2+8.231

Rewrite properly

So, we have

y = -0.0000081x³ + 0.00267x² + 8.231

From the question, we have

x represents the number of years after 1900

In 1950, x = 50

So, we have

Growth rate in 1950, y = -0.0000081 x 50³ + 0.00267 x 50² + 8.231

Growth rate in 1950, y = 13.9

In 1988, x = 88

So, we have

Growth rate in 1988, y = -0.0000081 x 88³ + 0.00267 x 88² + 8.231

Growth rate in 1988, y = 23.4

In 2010, x = 110

So, we have

Growth rate in 2010, y = -0.0000081 x 110³ + 0.00267 x 110² + 8.231

Growth rate in 2010, y = 29.8

Hence, the growth rate in 2010 is 29.8%

What is the y-intercept?

An exponential equation can be described as an equation with exponents. The exponent is usually a variable. When an exponential function is drawn on a coordinate graph, it is usually nonlinear because the slope is not constant.

The general form of exponential equation is f(x) = [tex]e^{x}[/tex]

Where:

x = the variable e = constant

Find the solution of this system of equations.
Separate the x- and y-values with a comma.
x = 10 + y
-3x + y = -28

Answers

We know that:

                      x = 10 + y

In the next equation {-3x + y = -28}  x is the same as the first, so:

-3(10 + y) + y = -28

-30 - 3y + y = -28

-30 - 2y = -28            

We add 30 to both sides:

-2y = 2

and divide both sides by (-2):

y = -1

Now we can put y = -1 to the first equation:

  x = 10 + y

  x = 10 - 1

   x = 9

So,

the solution of this system of equations is:                             (9, -1)

What is the inverse of ƒ (x) = (2x + 1)² for x ≥ −½1⁄?

Answers

The inverse of the given function is (f^-1)(x) = (1/2)×(√x  - 1) for x ≥ 0.

We are given a function f(x). The function f(x) is defined as (2x + 1)². The domain of the given function f(x) is x ≥ -1/2. We need to find the inverse of the function f(x).

Let us suppose that the function f(x) is represented by the variable "y".

y = f(x)

y = (2x + 1)²

Now we will take the square root on both sides of the equation.

√y = √[(2x + 1)²]

When we cancel out the even powers, we need to take the absolute value using modulus.

√y = |2x + 1|

We already know that x ≥ -1/2, so, modulus will open with a positive sign.

√y = +(2x + 1)

√y = 2x + 1

√y  - 1 = 2x

x = (1/2)×(√y  - 1)

At last, we replace the variables y and x by x and (f^-1)(x).

(f^-1)(x) = (1/2)×(√x  - 1) for x ≥ 0

What is congruent of the triangle?

The shapes maintain their equality regardless of how they are turned, flipped, or rotated before being cut out and stacked. We'll see that they'll be placed entirely on top of one another and will superimpose one another. Due to their identical radius and ability to be positioned directly on top of one another, the following circles are considered to be congruent.

Any two figures can be perfectly positioned over one another to demonstrate their congruence. The relationship between two figures that are said to be congruent is described using the word "congruence."

2y = 30-10

The residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was 7 to 5. If there were 6412 yes votes, what was the total
number of votes?

Answers

The total number of votes which is reduced by the ratios of yes and no votes will be: 4580; + 6412 = 10992;

What are Ratios?

Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorize ratios. Part to whole ratio is one, and part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings. For instance, a class has a 12:15 boy-to-girl ratio, whereas the part-to-whole ratio refers to the relationship between a particular group and the entire. For instance, five out of every ten people enjoy reading. As a result, the ratio of the part to the whole is 5: 10, meaning that 5 out of every 10 people enjoy reading.

In the given question, we have:

The ratio of yes votes to no votes was 7 to 5.

Total Number of Yes votes = 6412;

So, Let us assume the total number of no votes be x;

So, according to the question,

[tex]\frac{7}{5} = \frac{6412}{x}[/tex]

Cross Multiplying the terms:

⇒7 × x = 6412 ×5

⇒x = 4580;

So, The total number of no votes is 4580;

So, The total number of votes will be: 4580; + 6412 = 10992;

Hence,

The total number of votes will be: 4580; + 6412 = 10992;

In a discount clothing store, all sweaters are sold at one fixed price and all shirts are sold at another fixed price. If one sweater and four shirts cost $55, while four sweaters and five shirts costs $110, find the price of one sweater and the price of one shirt.

Answers

Answer:

Price of one shirt: $10Price of one sweater: $15

Step-by-step explanation:

The price of one sweater - x

The price of one shirt - y

From what the problem states, we can assume:

x + 4y = 55

4x + 5y = 110

Multiply both sides of x +4y = 55 by four. This results in 4x + 16y = 220. We then subtract 16y on both sides, resulting in 4x = 220 - 16y. We then insert this into the other equation, which, as a reminder, is 4x + 5y = 110. We replace 4x with 220 - 16y, which results in 220 - 16y + 5y = 110. Now, we can solve it.

220 - 16y + 5y = 110220 - 11y = 110110 - 11y = 0110 = 11yy = $10

Now that we have found out the value of y, we can replace all instances of y in the first equation.

x + 4y = 55x + 40 = 55x = $15
