The solutions for the given quadratic equation are:4/5 and 1/2.

The quadratic function can represent a quadratic equation in the Standard form: ax²+bx+c=0 where: a, b and c are your respective coefficients. In the quadratic function the coefficient "a" must be different than zero (a≠0) and the degree of the function must be equal to 2.

For solving a quadratic function you should find the discriminant:[tex]D=b^2-4ac[/tex]  . And after that you should apply the discriminant in the formula: [tex]x_{1,\:2}=\frac{-b\pm \sqrt{D}}{2a}[/tex].

For the given question, you have:

a=20

b=-26

c=8

[tex]D=b^2-4ac=\left(-26\right)^2-4\cdot \:20\cdot \:8=676-640=36[/tex]

[tex]x_{1,\:2}=\frac{-b\pm \sqrt{D}}{2a}\\ \\ x_{1,\:2}=\frac{-(-26)\pm \sqrt{36}}{2*20}\\ \\ x_{1,\:2}=\frac{\left26\right\pm \:6}{40}[/tex]

Then,

[tex]x_1=\frac{\left(26\right)+6}{40}=\frac{32}{40}=\frac{4}{5}[/tex]

[tex]x_2=\frac{\left26\right-6}{40}=\frac{20}{40}=\frac{1}{2}[/tex]

Answer:

Perimeter = 2 ( l + w )

if u r given for rectangle thats the formula

Step-by-step explanation:

To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width).

Answer:

4 books

Step-by-step explanation:

Answer:

a = 0, b = 7

a = 1, b = 6

a = 2, b = 5

a = 3, b = 4

a = 4, b = 3

a = 5, b = 2

a = 6, b = 1

a = 7, b = 0

Step-by-step explanation:

the sum of a and b must equal 7 because 4 x 7 = 28

Here is the complete question

here are 2 yellow, 3 green, 1 orange, and 4 red cards in a stack of cards turned facedown. Once a card is selected, it is not replaced. Find each probability.

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.

1. P(two yellow cards)

there are a total of 10 cards and 2 yellows cards. If 1 yellow card is picked, it would remain 1 yellow card and 9 cards

P(two yellow cards) = 2/10 x 1/9 = 1/45

b) m = 2.5

c) n = 3

d) x = 4

e) x = 2

Step-by-step explanation:

Just remember that whatever you do to one side of the equation, you must do to the opposite side. Your aim is to isolate x.

Answer: I worked it out and got D but I'm not 100% sure.

The correct option is option B: There were 6.27 times as many people who visited the aquarium on the 7th as on the first day.

The function which involves an exponent with a base so that the base is rises exponent times is called exponential function.

for example is f(x)=bˣ where b is base and x is exponent

Here it is given that

the following exponential equation:

y = A(b)ⁿ

where the following variables is defined as :

A: the initial number of customers applied

b: the rate of increase of the number of people applied every month

n: the number of months from the bank opened

Substituting values in the above exponential expression we have:

y = 64(1.3)⁷

y = 64*6.27

Therefore There were 6.27 times as many people who visited the aquarium on the 7th as on the first day.

Answer:

x = 5 ± √46

Step-by-step explanation:

[tex]-x^2 + 10x + 21 = 0[/tex]

Take -1 common from L.H.S.

[tex]=> -1(x^2 -10x - 21) = 0[/tex]

Take -1 to R.H.S.

[tex]=> x^2 - 10x - 21 = 0[/tex]

Solve x using quadratic formula.

[tex]=> x = \frac{-(-10) + \sqrt{10^2 - 4 \times (-21) \times 1} }{2 \times 1} \: or \:\frac{-(-10) - \sqrt{10^2 - 4 \times (-21) \times 1} }{2 \times 1}[/tex]

[tex]=> x = \frac{10 + \sqrt{100 + 84} }{2} \: or \:\frac{10 - \sqrt{100 + 84} }{2}[/tex]

[tex]=> x = \frac{10 + \sqrt{184} }{2} \: or \: \frac{10-\sqrt{184} }{2}[/tex]

[tex]=> x = \frac{10 + 2\sqrt{46} }{2} \: or \: \frac{10 - 2\sqrt{46} }{2}[/tex]

[tex]=> x = (5 + \sqrt{46} ) \: or \: (5 - \sqrt{46} )[/tex]
