Answer:

  a. P = 190t -373,930 . . . . . t=actual year number

  b. P = 6640

Step-by-step explanation:

Given the two points (1991, 4360) and (1999, 5880) on a linear relation between years and moose population, you want a formula for the population (P) and an estimate of the population in 2003.

We can use the point-slope form of the equation for a line to write the formula for moose population. To do that, we need to know the slope of the line.

The slope is given by the formula ...

  m = (y2 -y1)/(x2 -x1) . . . . . . . . line through points (x1, y1) and (x2, y2)

Using the given point values, we have ...

  m = (5880 -4360)/(1999 -1991) = 1520/8 = 190

The point-slope equation for a line with slope m through point (h, k) is ...

  y -k = m(x -h)

Using the first ordered pair, we can write the equation as ...

  y -4360 = 190(x -1991)

  y = 190x -373,930 . . . . . . . where x is the actual year number

Using P and t for the variables, the formula is ...

  P = 190t -373,930

Using t=2003, the above formula evaluates to ...

  P = 190(2003) -373,930 = 380,570 -373,930

  P = 6,640

The linear model predicts the 2003 population to be 6640 moose.

__

Additional comment

The formula above uses actual year number. The year value can be translated any way you might want. For example, using t = years after 1991, the formula would be ...

  P = 190(t +1991) -373,930

  P = 190t +4360

Then t=12 for year 2003.

The system of equations are:

c + b = 1285

Answer:

(10+t)*25

Step-by-step explanation:

25 students so the cost for 1 student needs to be multiplied by 25 for all the students

If lunch costs $10 by itself not including the ticket, we don't know how much the ticket costs so lets say ticket cost = t

$10+t = the cost for ONE student

but there are 25 students so, ($10+t)*25 could work

Expressions don't have equal signs so the total is  (10+t)*25

(x+√y)(x-√y) = x² - y is always an integer.

Given that x and y are integers.

Then x + √y is an irrational number.

The conjugate of (x + √y) is (x - √y).

We need to find the product (x + √y)(x -√y).

Use the identity, (a +b)(a-b) = a²-b²

So  (x + √y)(x -√y) = x² - (√y)²

                             = x² - y

Given that x is an integer. The square of an integer is always an integer.

Since x² and y are integers, their difference is also an integer.

So we can conclude that x²-y is an integer.

Hence, (x+√y)(x-√y) = x² - y is always an integer.

x = -1/4 is an extraneous solution.

✓(11x + 3) - 2x = 0

Adding 2x on both sides of the equation we get

✓(11x + 3) = 2x

Squaring both sides of the equation we get

(✓(11x + 3))² = (2x)²

11x + 3 = 4x²

4x² - 11x - 3 = 0 : Equation 1

By middle term splitting equation 1 can be written as

4x(x - 3) + 1(x - 3) = 0

(4x + 1)(x - 3) = 0

x = - 1/4 and 3.

Check extraneous solution by putting the value of x in the original equation -

Let x = -1/4

✓(11(-1/4) + 3) - 2(-1/4) = 0

The required expression or inequality for possible widths of the rectangle is -4 < x < 3.

Given:

A rectangle has a length 6 meters more than six times the  width.

The area of the rectangle is less than 72 meters  squared.

We have to find,

The expression or inequality that represents all possible  widths of the rectangle.

Let x be the width of the rectangle.

Length of the rectangle is 6 meters more than six times the  width.

length = 6x + 6

Area of rectangle is:

Area = length × width

Area = (6x + 6) × x

Area = 6x² + 6x

The area of the rectangle is less than 72 meters  squared.

6x² + 6x < 72

6x² + 6x -72 < 0

Divide both sides by 6.

x² + x - 12 < 0

x² + 4x - 3x - 12 < 0

x(x + 4) - 3(x + 4) < 0

(x + 4) (x - 3) < 0

It is true if one factor is negative and other is positive. So,

x - 3 < 0 ⇒ x < 3  ...(i)

x + 4 > 0 ⇒ x > -4  ...(ii)

Using (i) and (ii), we get

Step-by-step explanation:

Since the number 63 is a composite number, 63 has more than two factors. Thus, the factors of 63 are 1, 3, 7, 9, 21 and 63.

the pair of points that are at a distance of 4 units are (2, 7) and (2, 3), which is option D.

For two points defined by the coordinates (a, b) and (c, d), we define the distance between these two points as:

distance = √(( a - c)^2 + (b - d)^2)

So you can just use that simple formula for the four pairs of points given and see which pair gives a distance of exactly 4 units, if we use the last pair wich is (2, 7) and (2, 3) and we replace the values in the correspondent places of the distance equation, we will get:

distance = √( (2 - 2)^2 + (7 - 3)^2) = 4

Pittman–Robertson Act

The Pittman–Robertson Act (Federal Aid in Wildlife Restoration Act of 1937) requires an 11% excise tax to be paid on the sale of firearms, ammunition, and archery equipment to be used by state governments to fund wildlife restoration.

Given information:

The money raised for conservation can be calculated by finding 11% of the number of firearms sold multiplied by the average selling price.

[tex]\begin{aligned}\textsf{Money raised}&=11\% \textsf{ of }19,000,000 \times \$500\\\\& = \dfrac{11}{100} \times 19,000,000 \times 500\\\\& = \dfrac{11\times 19,000,000 \times 500}{100} \\\\& = \dfrac{104,500,000,000}{100} \\\\& = 1,045,000,000\end{aligned}[/tex]

Therefore, the total amount of money raised was $1,045,000,000 ($1.045 billion).

Answer:

Step-by-step explanation:

To calculate the amount of money raised for conservation from the sale of firearms during 2020, we'll follow these steps:

Step 1: Calculate the total revenue generated from firearm sales.

Total revenue = Number of firearms sold * Price per firearm

Total revenue = 19,000,000 * $500

Total revenue = $9,500,000,000

Step 2: Calculate the amount of excise tax collected.

Excise tax = Total revenue * Excise tax rate

Excise tax = $9,500,000,000 * 0.11

Excise tax = $1,045,000,000

Therefore, the amount of money raised for conservation from the sale of firearms during 2020, based on the given information, is $1,045,000,000.

Domain and Scope The domain of a function is the set of values that we are allowed to enter into our function. This collection includes the x values for a function like f. (x).

The range of values that a function can accept as input is known. When we enter an x value, the function returns this list of values.

All Real x, x not = 0 is the domain (the range of potential values for x).

Since 6/0, 8/0, and 12/0 are not defined, x = 0 is not considered.

All Real f(x), f(x) not = 0 is the range.

The simplest ratio of squares to total shapes will be 2:7.

A ratio in mathematics shows how many times one number is contained in another. When two objects are related using numbers or amounts, the relationship is known as a ratio. For instance, if a dish of the fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).

A ratio can have any number of quantities, such as counts of people or things or measurements of length, weight, time, etc. Both numbers must be positive in most situations. From the information, there are 4 squares as 10 triangles.

Therefore, the simplest ratio of squares to total shapes will be:

The greatest integer that is less than the value of the logarithm log17.52 is 1.

We are required to check the value of greatest integer that is less than log17.52

As no base is mentioned, let us consider the base to be 10

Thus, we are required to find the value of log₁₀17.52

log₁₀17.52=log₁₀10+log₁₀7.52

log₁₀10=1

log₁₀7.52=log₁₀752/log₁₀100

                =log₁₀752-2log₁₀10

If the Learning curve rate is 85%, then the painter will need 35.5 hours to pant all 20 rooms.

Learning curve rate tells us that there will be improvement or the time for the task will decrease as the person learn the repetitive task.

The time for completing n units is given by the formula:

Tₙ = T₁ . nᵇ

Where:

T₁  = time to complete 1st task

n = number of units

b = ln (learning curve rate) / ln(2)

The given parameters:

T₃  = 9 hours

learning curve rate = 85%

Hence,

b = ln (0.85) / ln(2) = 0.693

Plug the values into the formula for n = 3

T₃ = T₁ . 3ᵇ

T₁  = T₃ / 3ᵇ = 9 / 3ᵇ

Substitute the parameters for n = 20.

T₂₉ = T₁ . 20ᵇ

      = (9 / 3ᵇ) . 20ᵇ
