The minimum of y = f(x) occurs at (x,y) = (3,1). Hence y= f(x) >=1 for all other x in its domain of definition.

What is Quadratic equation ?

Quadratic equation can be defined as equation in which it is in the form of ax^2 + bx + c = 0

where c is a constant.

y = f(x) + 3 merely increases the value y by 3 for any x, or just raises its graph up 3. The x-value for its minimum remains at x=3 and y = f(3) + 3 = 1 + 3 = 4.  Hence, new minimum = (3,4)

y = f(x-2) just shifts or translates the graph of f to the right by 2.  So what occurred at x=3 (the minimum y) now occurs at x=5  without changing y = 1.  Hence, new minimum = (5,1).

y = f(1.5x) compresses the x-scale without changing y.  So what happened at x=3 before now happens at x'=2 on the new scale.

Therefore, the minimum point now becomes  (2,1).

Find two numbers whose difference is 303, hcf is 101 and are 4 digits long.

Start by writing down two 4-digit numbers that have a difference of 303. The two numbers should be close together, but not the same number. For example, you could choose 9801 and 9498.

Next, find the factors of each number. For 9801, the factors are 3 x 3 x 11 x 101 and for 9498 the factors are 2 x 7 x 13 x 101.

Now, find the Highest Common Factor (HCF) of the two numbers. To do this, you can look at the factors of both numbers and find which ones are the same. In this case, the HCF is 101.

Finally, check if the difference between the two numbers is still 303. As 9801-9498 = 303, this is correct. Therefore, 9801 and 9498 are the smallest pair of 4-digit numbers with a difference of 303 and an HCF of 101.

The length of line segment Dc is equal to 35 units.

In Mathematics, two geometric figures are considered to be congruent only when their corresponding side lengths are congruent and the magnitude of their angles are congruent.

Since side length DE is parallel to AB and side DE is 5 less than side length DC, we have the following:

DE = DC - 5

In Geometry, the corresponding side lengths of two similar geometric figures are proportionate and as such, we have the following:

DC/AC = DE/AB

DC/56 = DC - 5/48

48DC = 56(DC - 5)

48DC = 56DC - 280

Answer:Let's call the distance of the boat trip "d".

Since the whole trip took 5 hours, and Maxwell was driving for part of it, we know that:

d/40 + x/60 = 5

where x is the number of hours Maxwell spent driving.

We also know that the distance he drove is equal to the total distance minus the boat trip:

275 - d = x * 60

So we can substitute this into the first equation:

d/40 + (275 - d)/60 = 5

Expanding and simplifying this equation gives us:

6d = 1800

Finally, dividing both sides by 6 gives us:

d = 300

So the boat trip was 300 miles long.

Using the concept of ratio in the similar triangles, the length scale factor is 1:25

Similar triangles are triangles that have the same shape but may be scaled differently. Two triangles are considered similar if and only if their corresponding angles are congruent (equal in measure) and the ratio of their corresponding sides is the same. This property is known as the "AA Similarity Postulate" or "Angle-Angle Similarity".

In other words, similar triangles have the same shape and proportional sides. This means that if two triangles are similar, corresponding sides are in proportion and corresponding angles are equal in measure.

In the given figures, the two triangles have areas of 3m² and 75m²

The formula of area of a triangle is given as ;

A = 1/2 (b * h)

Assuming the side lengths are equal, we can apply heron's formula which is given as;

S = [a + b + c / 2]

A = √s(s - a)(s - b)(s - c)

But a = b = c

Using the two triangles to find the ratio between the ratios;

Q : R = 3 : 75 = 1 : 25

The length will be given as;

Area = 1/2 b * h

b = h

75 = 1/2 * a * a

a² = 75 * 2

a² = 150

a = √150

3 = 1/2(b²)

Opposite sides are congruent (AB = DC).

Opposite angels are congruent (D = B).

Consecutive angles are supplementary (A + D = 180°).

If one angle is right, then all angles are right.

The four properties of parallelogram are:

i) Opposite sides are parallel & equal.

ii) Sum of adjacent interior angles is 180°

iii) Opposite angles are equal.

iv) Diagonals bisect each other.

The quadrilateral with two pairs of parallel sides is known as a parallelogram. Equal in length and width on both sides is required. Four vertices make up a parallelogram, which also has four edges.

A parallelogram is a two-dimensional (2D) shape that has two matching pairs of opposite sides that are parallel and equal in length. The angles inside the two sides of the shape must add up to 180 degrees, which means that all of the angles must add up to 360 degrees.

A rectangle that has been pushed over slightly is all that a parallelogram really is. Because of this, finding the area of a parallelogram can be done using the same formula as finding the area of a rectangle.

Equation of the sphere with center (-5, -3, 0) and radius 1 is (x + 5)² + (y + 3)² + z² = 1.

All points on a sphere are at a set distance from the centre, making it a three-dimensional geometric object. It is thought to be one of the most basic three-dimensional shapes and is a perfect circle.

Both a circle and a sphere are round, if you compare them. The fact that we can measure the volume and area of a sphere is due to the fact that a sphere is three-dimensional as opposed to a circle, which is a two-dimensional shape.

It is possible to formulate the equation for a sphere with centre (h, k, l) and radius r as follows:

(x - h)² + (y - k)² + (z - l)² = r²

Using the given center (-5, -3, 0) and radius 1, we can write the equation of the sphere as:

(x + 5)² + (y + 3)² + (z)² = 1²

which simplifies to:

(x + 5)² + (y + 3)² + z² = 1.

The point-slope formula can be used to get the equation of the tangent line to the graph of the function f(x)=(x2 - 9)(x - 4) at the point (1, -30).

To get the slope at the position (1, -30), first take the derivative of the function:

f'(x) = (x2 - 9) (x2 - 9)

(x - 4)' = 2x - 9/x - 4

Check the derivative at x = 1 now:

f'(1) = 2(1) - 9/(1) - 4 = -93

The line has a -93 slope.

Now, enter the point-slope formula the point (1, -30) and the slope (-93):

y - (-30) = -93(x - 1) (x - 1)

If we simplify, we get:

y = -93x + 22

As a result, y = -93x + 22 is the equation of the tangent line to the graph of the function f(x)=(x2 - 9)(x - 4) at the point (1, -30).

The point-slope formula can be used to get the equation of the tangent line to the graph of the function f(x)=(x2 - 9)(x - 4) at the point (1, -30). According to the point-slope formula, the equation of the line is y - y1 = m for a given point (x1, y1) and slope (m) (x - x1). The specified point in this instance is (1, -30), and the slope of the line may be calculated by calculating the function's derivative and evaluating it at x = 1. The derivative of the function f(x) is 2x - 9/x - 4, which for x = 1 translates to -93. When the point and slope are entered into the point-slope equation, we obtain the result y - (-30) = -93(x - 1), which is abbreviated to y = -93x + 22. As a result, y = -93x + 22 is the equation of the tangent line to the graph of the function f(x)=(x2 - 9)(x - 4) at the point (1, -30).
