What is the root when talking about a quadratic equation

Answers

Answer 1

The root is the x intercepts or the zeros of the problem

If I were to graph

(x-5)(x+4)=0

We need a number for x which makes this equation 0

The numbers are 5 or -4

These are the x intercepts of the parabola or roots

Answer 2

Answer:

The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.

Ja’quan was told to go inside one afternoon while he was at summer camp. He heard thunder and saw flashes of lightning. Suddenly, small balls and chunks of ice were falling on the field. Ja’quan checked the thermometer, because he never saw ice fall in South Florida, and noticed that it was 77°F (or 25°C). How was ice able to fall even though the temperature was much warmer than freezing?

a) Ja’quan read the thermometer wrong
b) He must have observed hail falling from thunder clouds

a spinner has 8 equal sections,6 are green .find probability that will land on green​

Answers

Answer:

P(A) and P(B) = P(A) x P(B)

P(A) = number gray/total number of sections = 6/8 = 3/4

P(B) = number of reggae songs/total number of songs = 2/8 = 1/4

P(A) and P(B) = (3/4)(1/4) = 3/16

Step-by-step explanation:

Answer: 3/4 (0.75)

Step-by-step explanation:

6 out of 8 sections are green.

So there is a 6/8 probability that it will land on green.

6/8 = 3/4.

Can someone please help me

Answers

Answer:

19.0 cm

Step-by-step explanation:

a^2+b^2=c^2

1^2+b^2=19^2

1+b^2=361

(subtract one from both sides)

b^2=360

(now square root to get rid of the ^2)

[tex]\sqrt{b^2}[/tex]=[tex]\sqrt{360}[/tex]

b=18.97 rounded to the tenths place is 19.0

Answer:

The length of the other leg is 19 cm (rounded to the nearest tenth).

Step-by-step explanation:

In order to solve this, we need to know the Pythagoras theorem which states that...

[tex]c^{2} = a^{2} +b^{2}[/tex]  (Where c is the length of the hypotenuse and a and b are the lengths of the legs)

Now just substitute the values to find the length of the other leg, and we get...

[tex]c^{2} = a^{2} +b^{2}\\19^{2} = 1^{2} + b^{2} \\b^{2} = 19^{2} - 1^{2} \\b^{2} = 361 - 1\\b^{2} = 360\\b = \sqrt{360} \\[/tex]

b ≅ 19

Therefore the length of the other leg is around 19 cm.

Answers

Answer:

(x+4)x

Step-by-step explanation:

The factor of the expression into an equivalent form x² + 4x would be;  x(x + 4)

What are equivalent expressions?

Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.

To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.

We need to factor the expression into an equivalent form x² + 4x

This expression could also be given by;

x² + 4x

Then factor out x we get;

x² + 4x =  x(x + 4)

Hence, the expression into an equivalent form x² + 4x would be; x(x + 4)

determine the domain of the following graph

Answers

Answer:

[-5, 10) or you can write [tex]-5\le x < 10[/tex]

Step-by-step explanation:

The domain is the set of all values of x used in the function. Scan across the graph from left to right (much as you do when reading). The first point you find on the graph has an x-coordinate 5 (see the solid dot?). Then, as you continue reading across the graph, there are values of x used until you get to 10. The dot at x = 10 is open, not filled in. That indicates that the number x = 10 is NOT used by the function.

So the domain is all real numbers greater than or equal to -5 and less than 10.

[-5, 10) is called interval notation; a square bracket means the value next to it IS used by the function, a parenthesis means the value next to it is NOT used.

Find the radius of a sphere with a volume of 180 cubic feet. Round your answer to the nearest tenth.

Answers

Answer:

3.50ft

Step-by-step explanation:

Given data

Volume= 180ft^3

The expression for the volume of a sphere is given as

Volume=4/3πr^3

substitute

180=4/3*3.142*r^3

180=12.568/3*r^3

180=4.189*r^3

r^3= 180/4.189

r^3= 42.969

cube root both sides

r= ∛ 42.969

r= 3.50ft

Hence the radius is 3.50ft

Caterers made 272 cups of punch for a party. They will distribute the punch equally into 6 bowls. How many cups of punch will each bowl have? A. B. C. D.

Answers

Answer:

45.33 cups.

Step-by-step explanation:

272 divided by 6 gives this answer

The number of cups of punch each bowl will have is given by the equation A = 45.3 cups

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of cups of punch in each bowl be represented as A

Now , the equation will be

The total number of cups of punch = 272 cups

The number of bowls = 6 bowls

So , the number of cups of punch in each bowl A = total number of cups of punch / number of bowls

Substituting the values in the equation , we get

The number of cups of punch in each bowl A = 272/6

The number of cups of punch in each bowl A = 45.3 cups

Therefore , the value of A is 45.3 cups

Hence , the number of cups in each bowl is 45.3 cups
