The axis of symmetry for a function in the form f(x) = x2 + 4x − 5 is x = −2. What are the coordinates of the vertex of the graph?

(−9, −2)
(−17, −2)
(−2, −17)
(−2, −9)

Answers

Answer:

D) [tex](-2,-9)[/tex]

Step-by-step explanation:

Vertex Form of a Vertical Parabola:

[tex]y=a(x-h)^2+k[/tex]

Vertex -> [tex](h,k)[/tex]

Axis of Symmetry -> [tex]x=h[/tex]

Vertical Scale Factor -> [tex]a[/tex]

To turn [tex]f(x)=x^2+4x-5[/tex] into vertex form, we need to complete the square on the right sideTherefore, if [tex]f(x)=0[/tex], then [tex]0+9=x^2+4x-5+9[/tex] completes the square on the right side This becomes [tex]9=(x+2)^2[/tex]This means that our function in vertex form is [tex]f(x)=(x+2)^2-9[/tex]

Therefore, the vertex of the graph is [tex](h,k)=(-2,-9)[/tex].

The coordinates of the vertex of the graph is (-2, -9).

What are Quadratic Functions?

Quadratic functions are polynomial functions consisting of variables and exponents and the degree of the variable is 2.

The general form of a quadratic function is f(x) = ax² + b x + c.

Given is a quadratic function,

x² + 4x - 5

Given that axis of symmetry of the function is x = -2.

So the x coordinate of the vertex = -2.

y coordinates = f(-2) = 4 - 8 - 5 = -9

Hence the vertex is (-2, -9).

Who has given the correct answer, justify

Answers

Answer:

10.

Step-by-step explanation:

Explanation:

[tex]12 - 6 + 4[/tex]

In order to solve this, we must use PEMDAS.

This is because there are more than one operations involved.

PEMDAS is the order in which you must solve the operations.

PEMDAS STANDS FOR:

ParenthesisExponential Notation (exponents)Multiplication/division (do whichever comes first)Addition/subtraction (do whichever comes first)

Solve.

Now, using PEMDAS, I will solve.

There are no parenthesis.

There are no exponents.

There is no multiplication nor division.

There is addition and subtraction.

[tex]12-6+4[/tex]

[tex]12-6=6[/tex]

[tex]6+4[/tex]

Lastly, there is addition.

[tex]6+4=10[/tex]

Conclude:

I, therefore, believe [tex]12-6+4=10.[/tex]

You did not clarify the answers of Jagan nor Mithun.

So, whichever person got the answer of 10 is correct.

What is the atmospheric pressure?
a. 4.7 pounds per square inch

b. 13.2 pounds per square inch

c. 1.7 pounds per square inch

d. 14.7 pounds per square inch

Answers

Answer:

Step-by-step explanation:

The atmospheric pressure is about 101325Pa.

Pascal is a unit for pressure and since pressure can be defined as force/ area, the pressure can also be written as 101325 N/m².

1 m² ----- 101325 N

Pounds is a unit for mass, so let's relate force (Newtons) to mass.

[tex]\boxed{F = ma}[/tex]

☆ where F= force, m= mass and a= acceleration due to gravity

Since the gravitational field strength is about 9.8 N/kg on earth, a= 9.8.

101325= m(9.8)

m= 10339 Kg (5 s.f.)

Since 1 kg is about 2.205 pounds,

= (10339 ×2.205) pounds

= 22797.495 pounds

= 22797 pound (5 s.f.)

1 m² ----- 22797 pounds

Now convert m² to in².

1 m² is about 1550 in², thus

1550 in² ----- 22797 pounds

1 in²----- 22797 ÷1550

1 in² ----- 14.708 pounds (5 s.f.)

1 in² ----- 14.7 pounds (3 s.f.)

Thus, 1 atm≈ 14.7 pounds per square inch.

Answers

Answer:

See below for answer and explanations (as well as an attached graph)

Step-by-step explanation:

Pay attention to the behavior of the asymptotes. If the asymptotes are approaching a certain x-value or y-value, then that value is undefined for the function.

Take for example [tex]y=\frac{1}{x}[/tex]:

As x approaches ∞ and -∞, then y approaches 0, which is our horizontal asymptoteAs y approaches ∞ and -∞, then x approaches 0, which is our vertical asymptote
