What is a quadratic equation?

f(x) = ax2 + bx + c, where a, b, and c are integers and an is not equal to zero, is a quadratic function.

A parabola is the shape of a quadratic function's graph. Although the "width" or "steepness" of a parabola can vary as well as its direction of opening, they always have the same fundamental "U" form. The three graphs in the image below are all parabolas.

The following must be true if those are the 0s:

-2 + 2 = 0

8 - 8 = 0

We would thus get the following equation if we were to include them in a quadratic-based one:

Answer:

f(x) = x2 − 6x − 16

Step-by-step explanation:

Write the zeros as solutions of two equations.

x  =  −2  x  =  8  

x + 2  =  0   x − 8  =  0  Rewrite each equation so that it equals 0.

Find the product of the two binomials.

(x + 2)(x − 8)  =  x2 − 8x + 2x − 16   Multiply.

=  x2 − 6x − 16  Simplify.

Rewrite the equation in function notation.

f(x) = x2 − 6x − 16

Therefore, the quadratic function with zeros of −2 and 8 is f(x) = x2 − 6x − 16.

A quadrilateral has a perimeter of 12 and all of the side lengths are odd integers. What is the probability that the quadrilateral is a rhombus?

Answers

A quadrilateral has a perimeter of 12 and all of the side lengths are odd integer then the probability that the quadrilateral is a rhombus is 1/4.

What is perimeter ?

If the midpoints of a rhombus with 12-inch sides are connected, a quadrilateral is created. A square with a 12-inch diagonal would be the quadrilateral that is constructed.

A perimeter is a closed path that encloses, surrounds, or delimits a one-dimensional length, a two-dimensional shape, or both. The circumference of a circle or an ellipse is its perimeter. There are numerous practical uses for calculating the perimeter.

All four side lengths must be added up in order to determine the perimeter, or the distance around the rectangle. Since there are two of each side length, it is simple to multiply the total of the length and the breadth by two in order to accomplish this task efficiently.

The given arithmetic series:

Notice that:

a(1) = x

a(2) = x+y

a(3) = x+2y

We can find the common difference:

d = a(2) - a(1)

Recall the formula for the nth term of an arithmetic series:

a(n) = a(1) + (n - 1) . d

Substitute n = 10, a(1) = x, and d = y into the formula:

a(10) = x + (10 - 1)y

Austin runs a farm stand that sells raspberries and apples. Each pound of raspberries sells for $4 and each pound of apples sells for $1.50. Austin made $267.50 from selling a total of 95 pounds of raspberries and apples. Determine the number of pounds of raspberries sold and the number of pounds of apples sold.

Answers

Answer:

50 pounds of raspberries and 45 pounds of apples is sold

Solution:

Let  "a" be the number of pounds of raspberries sold

Let "b" be the number of pounds of apples sold

Cost of each pound of raspberry = $ 4

Cost of each pound of apple = $ 1.50

Austin made $267.50 from selling a total of 95 pounds of raspberries and apples

Therefore,

a + b = 95

b = 95 - a ------ eqn 1

Austin made $267.50. Therefore,

number of pounds of raspberries sold x Cost of each pound of raspberry + number of pounds of apples sold x Cost of each pound of apple = 267.50

4a + 1.50b = 267.50 --------- eqn 2

Substitute eqn 2 in eqn 1

4a + 1.5(95 - a) = 267.50

4a + 142.5 - 1.5a = 267.50

2.5a = 125

a = 50

Substitute a = 50 in eqn 1

b = 95 - 50

b = 45

Thus 50 pounds of raspberries and 45 pounds of apples is sold

Find the geometric mean between each pair of numbers.
18 and 1.5

Answers

The geometric mean between the pair of numbers, 18 and 1.5, is 3√3.

Geometric mean, like arithmetic mean, is a kind of average and a measure of central tendency.

To solve for the geometric mean, we multiply the numbers together and then take a square root (for two numbers), cube root (for three numbers) etc. In other words, geometric mean is the nth root of the product of n values.

The formula for the geometric mean is given by:

GM = n√x1 x2 . . . xn

Solving for the geometric mean between 18 and 1.5 using the formula:

GM = n√x1 x2 . . . xn

where n = 2, x1 = 18, and x2 = 1.5

GM = √(18)(1.5)

GM = √27

GM = 3√3

The y-intercept is the value of y when x=0 (or alternately the solution point of the form 90,y)). since x neq 0 not matter what value is assigned to y, no such point exists (graphically x=-2 is a vertical line parallel to, and therefore never intersecting, the Y-axis).

Find the missing term of each arithmetic sequence.14,..., 28, ...........

Answers

The missing terms of the given arithmetic sequence AP are 14, 21, 28, 35.

What exactly is arithmetic progression?

An arithmetic progression (AP) is a sequence with the same distinctions between each successive term.

Each term (apart from the first) in an arithmetic progression is derived by adding a specific number to the term before the first one.For the initial term 'a' of an AP as well as the common difference 'd,' the very next arithmetic progression equations are frequently used to solve different AP problems.An AP's most common difference 'd': d = a2 - a1 = a3 - a2 = a4 - a3 =...... = a - an-1. nth term of an AP: an = a + (n - 1) dThe sum of an AP's n terms is: Sn = n/2(2a+(n-1)d) = n/2(a + l), where l is the AP's final term.

Now, in response to the question;

The arithmetic sequence.14,..., 28, ............

There are total 4 terms in the series.

Let the initial term is  'a₁' is given as 14.

Let the second term is 'a₂'.

Let the third term be 'a₃' which is given as 28.

Ans, the let the fourth term is represented as 'a₄'.

As, we know that in the AP, the difference of the two consecutive terms is equal and called as common difference.

Thus,

d = a₂ - a₁      ........(equation 1)

d = a₃ - a₂     .......(equation 2)

Thus, equating the two equation;

a₂ - a₁ = a₃ - a₂

Substituting the values;

a₂ - 14 = 28 - a₂

Simplifying the equation;

2a₂ = 28 + 14

2a₂ = 42

a₂ = 21.

Put the obtained value in equation 1 and find d.

d = a₂ - a₁

d = 21 - 14

d = 7

Now, estimate a₄.

a₄ = a₃ + d

a₄ = 28 + 7

a₄ = 35

Therefore, the complete arithmetic sequence is 14, 21, 28, 35.

How many kilometres on the ground is represented by 9 cm on the map?

Answers

2.25 kilometers on the ground is represented by 9cm on the map

According to the question, the scale on the map is in the ratio 1 : 25000

That is the     length on the map = length of the ground

                               1cm = 25000 cm

                                1 cm = 25000/100000 km

                                1 cm = 0.25 km

Now we have to find the length of the ground in kilometres which is represented by 9cm on the map

That is we have to find the ratio,  9cm : x km

As from above, we know that,

                          1cm = 0.25 km

                           9 cm = 0.25*9 km

                                    = 2.25 km
