Answer:

6,072

Step-by-step explanation:

5,600 - 4,420 = 1,180

They gained 1,180 people over 5 years.  Now we need to find how many people they gain every year (roughly).

Since it's 5 years, we are going to divide.

1,180 / 5 = 236

They gained 236 people over 1 year.  Since 1998 is two years is before 2000, we're going to multiply 236 by 2.

236 x 2 = 472

Now we add this to the 1998 population.

5,600 + 472 - 6,072

The population in the year 2,000 is 6,072

The required standard form of the quadratic function that has the indicated vertex and whose graph passes through the given point is y = -2x² + 12x - 17.

The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.

To find the quadratic function that has the vertex (3, 1) and passes through the point (5, -7), we can use the vertex form of the quadratic function: y = a(x - h)² + k, where (h, k) is the vertex.

First, we substitute the vertex (5, -7) into the vertex form to find a:

y = a(x - 3)² + 1

-7 = a[2]² + 1
a = -2

Since a = -2, the standard form of the quadratic function is:

y = -2x² + bx + c

Substitute the point (5, -7) into the standard form y = -2x² + bx + c to find b and c:

-7 = -2x² + b(5) + c

-7 = -50 + 5b + c

43 = 5b + c - - - - -(1)

Substitute the point (3, 1) into the standard form y = -2x² + bx + c to find b and c:

1 = -18 + b(3) + c

19 =3b + c - - - - -(2)

Solving equations 1 and 2 we get
43 - 19 = 2b
b = 12 and c = -17

Put a,b and c in the standard equation,
y = ax² + bx + c
y = -2x² + 12x - 17

Answer:

To find the dimensions that would guarantee the greatest possible area, we can use the formula for the area of a rectangle, which is A = l * w, where l is the length and w is the width.

Since one side of the garden is already boarded by a river, we only need to use 600ft of fencing for the other three sides. This means that the length and width of the garden must add up to 600ft. We can write this as:

l + w = 600

Since we want to find the dimensions that would give us the greatest possible area, we want to maximize l * w. Using the formula for the area of a rectangle, we can write this as:

A = l * w = l * (600 - l) = 600l - l^2

To find the maximum area, we can differentiate this equation and set it equal to zero:

dA/dl = 600 - 2l = 0

Solving for l, we get:

l = 300/2 = 150ft

So, the shorter side is 150ft and the longer side is 450ft (600 - 150).

Finally, we can use the formula for the area of a rectangle to find the greatest possible area:

A = 150 * 450 = 67,500ft^2

Therefore, the greatest possible area for the garden is 67,500ft^2 when the shorter side is 150ft and the longer side is 450ft.

The unit rate of the shirt is $1.50 per shirt.

Unit rate is a measure of the relationship between two quantities, where the second quantity is expressed as a unit of one. It is often expressed as a ratio, with the unit of the second quantity being 1. Unit rate helps us compare different quantities and make sense of their relative sizes.

The unit rate for the shirts can be calculated by dividing the total cost by the number of shirts. In this case, the unit rate would be:

$6.00 ÷ 4 shirts = $1.50/shirt

The fraction cannot be worked out, given the information on the numerator being even and the denominator being odd.

When fractions are said to be in their simplest forms as 1 / 1, then it means that both the numerator and the denominator are the same. This way, they can divide each other and leave one.

For such a situation to happen, the numbers will have to either both be even numbers, or odd numbers. The numerator cannot be even while the denominator is odd.

The values for g and f for the length of sides of the trapezium are 8 and 6 respectively.

Given the area of trapezium = 60 cm², then:

1/2 × (g + 4g) × f = 60 cm²

by simplification

f(g + 2) = 60 cm²...(1)

for the area of ABCD = 48 cm², then:

f × g = 48 cm²

f = 48/g...(2)

put 48/g for f in equation (1) to get g;

48/g(g + 2) = 60

60g = 48g + 96 {cross multiplication}

60g - 48g = 96 {collect like terms}

12g = 96

g = 96/11 {divide through by 11}

Answer:

              The correct scale faction the first pentagon dilated by to create the second pentagon is 1.25.

Step-by-step explanation:

              Since the second pentagon is a dilation of the first pentagon, we can conclude these pentagons are similar, meaning the shape retained all of its previous angles, and all the corresponding sides are dilated by a common scale factor. Since we know the values of a pair of corresponding sides, we can use those to find the scale factor of dilation.

             The corresponding side of the original pentagon is 4 units, and the corresponding side of the dilated pentagon is 5 units. Since the first pentagon dilated to become the second, in order to solve the scale factor the pentagon dilated by, we'd have to divide the side given on the second pentagon by the corresponding side of the first, which will be 5 ÷ 4 = 1.25. Therefore, that will be the scale factor the pentagon dilated by.

The value of x for the equation is -10.

To simplify simply means to make anything easier. In mathematics, simplifying an equation, fraction, or problem means taking it and making it simpler. Calculations and problem-solving techniques simplify the issue. By eliminating all common factors from the numerator and denominator and putting the fraction in its simplest/lowest form, we can simplify fractions.

Given equation,

-3/4(x + 2) = 6

both sides multiply by -4/3

-3/4(x + 2) * -4/3 = 6 * -4/3

x + 2 = -8

subtract 2 from both sides

x + 2 - 2 = -8 - 2

To find the area of the base of the column, we need to find the expression for the radius of the column, r, in terms of x.

The volume of a column can be calculated as V = πr²h, where r is the radius, h is the height, and π is pi.

Using the given expression for the volume of the column, we can write:

πr²h = x³ + 37x² - 110x + 400

Since h = x + 40, we can substitute to get:

πr²(x + 40) = x³ + 37x² - 110x + 400

Dividing both sides by π(x + 40) gives us:

r² = (x³ + 37x² - 110x + 400) / (π(x + 40))

Finally, taking the square root of both sides gives us the expression for the radius in terms of x:

r = √((x³ + 37x² - 110x + 400) / (π(x + 40)))

So, the expression that approximates the area of the base of the column in terms of x and π is:

A = πr² = π √((x³ + 37x² - 110x + 400) / (π(x + 40)))²

The equation of the parabola is x² - 8x + 16 = 0

To find the equation of the parabola with focus (4, -3) and directrix y = -3, we can use the definition of a parabola.

A parabola is the set of all points that are equidistant to the focus and the directrix.

The distance from a point (x, y) to the directrix y = -3 is simply the vertical distance between the point and the line, which is |y - (-3)| = |y + 3|.

The distance from a point (x, y) to the focus (4, -3) can be found using the distance formula:

d = √[(x - 4)² + (y + 3)²]

Since the point is equidistant to the focus and the directrix, we have:

d = |y + 3|

Squaring both sides, we get:

(x - 4)² + (y + 3)² = (y + 3)²

Simplifying, we get:

(x - 4)² = 0

Thus, the equation of the parabola is simply:

x² - 4x - 4x + 16 = 0

x² - 8x + 16 = 0

To find three additional polar representations of the point (2, 3π/4), we can add or subtract 2πk to the angle, where k is an integer. Using this method, we get:

   (2, -5π/4) - subtract 2π

   (2, 11π/4) - add 2π

   (2, -3π/4) - subtract 2π

To find the smallest and largest values of the angle, we need to consider the interval −2π < θ < 2π. The given angle of 3π/4 lies in the second quadrant. Adding or subtracting 2π to this angle will give us angles in the third and fourth quadrants. Therefore, the smallest value of the angle is −3π/4, and the largest value is 5π/4. Thus, the polar representations are:
