A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

A product of two fractions - 2/5 and 2/5 is given.

We know in the product of fractions numerator is multiplied by the numerator and the denominator is multiplied by the denominator.

Answer:

(-1,-3)

Step-by-step explanation:

See the attached worksheet.  First step is to apply the transformation.  Modifiy the x and y points as per the instructions.  The transformed triangle is shown in blue and the coordinates are listed.  As the directions indicate, it is slipped down by 2 and to the left by 3 (y-2 and x-3).

Next, convert the x values so that they are reflected across the y axis.  The table shows that all x values are the negative of their original values.  The reflected triangle is shown in red.

The new point Z is (-1,-3).

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:

   (2, 3π/4)

   (2, -5π/4)

   (2, 11π/4)

   (2, -3π/4)

   (2, 5π/4)

The provided parallelogram has angles of 45 degrees and 45 degrees, as well as 48 degrees and 48 degrees.

A parallelogram is a basic quadrilateral with two pairs of parallel sides in Euclidean geometry. A parallelogram's opposing or facing sides are of equal length, and its opposite angles are of equal measure. A parallelogram is a quadrilateral with opposing sides that are parallel and equal. It has equal interior opposite angles. In addition, the angles on the same side of the transversal add up to 180 degrees or are additive to each other.

Here,

A parallelogram has two pairs of opposite angles that are equal.

Since one angle of the parallelogram is 48 degrees, its opposite angle must also be 48 degrees.

The other two angles must add up to 90 degrees (since they form a right angle), so they must each be equal to 180 - 90 = 90 degrees / 2 = 45 degrees.

So, the other angles of the parallelogram are 45 degrees and 45 degrees.

The angles of given parallelogram are 45 degrees and 45 degrees as well as 48 degrees and 48 degrees.

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:

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

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.

Step-by-step explanation:

[tex]\frac{1}{-6x}[/tex]  To get a positive exponent, put the expression over 1.

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
