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
Answer:
D
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,
m
= (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
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.

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)
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).

How do you find the equations of the vertical and horizontal asymptotes for a graph when you only have the graph and no function?
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 asymptoteSee the graph for a visual.

A city has 20 radio stations including 5 college stations. What is the probablility that a randomly chosen radio station in this city is a college radio station
Answer:
1/4
Step-by-step explanation:
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 is attached to the event. If it doesn't a value of zero is attached to the event.
the probability that a randomly chosen radio station in this city is a college radio station = number of college stations / total number of city radio stations
