Answer:
Famous mathematician Archimedes of Syracuse did the first calculation of pi around 250 BC. Without pi, we cannot calculate the ratio of the circumference of a circle to its diameter. Pi is made up of 31.4 trillion digits. Within pi, you can find your birthday, social security number, and every word ever if put into alphabetic values (1=a, 2=b, etc). You can get your entire life story from beginning to end just from pi!

What is the correct order of mass from least to greatest?
[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
As we know,
[tex] \sf \qquad density = \dfrac{mass}{volume} [/tex]
So, we can infer that :
[tex] \sf \qquad mass= {density} \cdot{volume} [/tex]
Now, let's calculate the mass of gases in each case :
Case A : Hydrogen ~[tex]\qquad \sf \dashrightarrow \:mass = 0.09 \times (15) {}^{3} [/tex]
[tex]\qquad \sf \dashrightarrow \:mass = 0.09 \times 3375 {}^{} [/tex]
[tex]\qquad \sf \dashrightarrow \:mass = 303.75 \: \: mg {}^{} [/tex]
or
[tex]\qquad \sf \dashrightarrow \:mass =0. 30375 \: \: g {}^{} [/tex]
Case B : Helium ~[tex]\qquad \sf \dashrightarrow \:mass =0. 175 \: \cdot \: (14 \sdot 12 \sdot10)[/tex]
[tex]\qquad \sf \dashrightarrow \:mass =0. 175 \: \cdot \: 1680[/tex]
[tex]\qquad \sf \dashrightarrow \:mass =0. 175 \: \cdot \: 294 \: \: mg[/tex]
or
[tex]\qquad \sf \dashrightarrow \:mass = 0.294 \: \: g[/tex]
Case C : Nitrogen ~[tex]\qquad \sf \dashrightarrow \:mass = 1.251\: \cdot \: \dfrac{4}{3} \cdot3.14 \cdot(4) {}^{3} [/tex]
[tex]\qquad \sf \dashrightarrow \:mass = 0.417\: \cdot \: 803.84[/tex]
[tex]\qquad \sf \dashrightarrow \:mass = 335.201 \: \: mg[/tex]
or
[tex]\qquad \sf \dashrightarrow \:mass = 0.335 \: \: g[/tex]
So, the arrangement of masses from least to greatest is :

What is the equation of the quadratic function with a vertex at (2,–25) and an x-intercept at (7,0)? f(x) = (x – 2)(x – 7) f(x) = (x 2)(x 7) f(x) = (x – 3)(x 7) f(x) = (x 3)(x – 7)
The quadratic equation with the given characteristics is:
f(x) = (x + 3)*(x - 7).
How to get the quadratic equation?We know that the vertex must be (2, -25) and it passes through (7, 0).
For a quadratic equation:
y = a*x^2 + b*x +c
The x-value of the vertex is:
x = -b/2a
Then we have:
2 = -b/2a
We also have:
-25 = a*4 + b*2 + c
And because the function passes through (7, 0) we know that 7 is one of the roots, then:
0 = a*49 + b*7 + c
Then we have 3 equations to work with:
2 = -b/2a
-25 = a*4 + b*2 + c
0 = a*49 + b*7 + c
If we subtract the third and second equations we get:
25 = a*45 + b*5
Now, with the first equation we can rewrite:
a = -b/4
Replacing that in the other equation:
25 = a*45 + b*5
25 = (-b/4)*45 + b*5 = b*(-25/4)
25*(-4/25) =b = -4
Now we know the value of b.
2 = -(-4)/2a
a = 1
Now we need to find the value of c, we have that:
0 = 1*49 + -4*7 + c
0 = 49 - 28 + c
0 = 21 + c
Then c = -21
The equation is:
[tex]y = x^2 - 4x - 21[/tex]
It can be factorized to:
f(x) = (x + 3)*(x - 7).

A tunnel on a bike trail is being designed similar to the picture below. The height of the new bike tunnel, y, in feet, is given by the following equation, where x is the horizontal distance, in feet, from the center line of the opening of the tunnel. Note that negative x-values indicate the distance to the left of the center line, and positive x-values indicate the distance to the right of the center line. Plot the points on the graph where the height of the tunnel is a maximum and where the height of the tunnel is zero feet.
we have that
[tex]y=-x^2+36[/tex]
we know that
Is the equation of a vertical parabola open down
so
the vertex is a maximum
step 1
convert the equation of the parabola in the vertex form
[tex]y=-x^2+36[/tex]
[tex]y-36=-x^2[/tex]
the vertex (h,k) is the point (0,36)
Part a) The point on the graph where the height of the tunnel is a maximum is (0,36)
Part b) The points on the graph where the height of the tunnel is zero feet is when y=0
so
for y=0

Which expresses this solution?
The equation that expresses the solution to the quadratic equation x² - 10x + 13 = 0 is [tex]x =5 \pm 2\sqrt{3}[/tex]
How to express the solution?The equation is given as:
x² - 10x + 13 = 0
The solution to a quadratic equation is represented by:
[tex]x =\frac{-b \pm \sqrt{b^2 -4ac}}{2a}[/tex]
So, we have:
[tex]x =\frac{10 \pm \sqrt{(-10)^2 -4 * 1 * 13}}{2 * 1}[/tex]
Evaluate the radicand
[tex]x =\frac{10 \pm \sqrt{48}}{2}[/tex]
Take the square root of 48
[tex]x =\frac{10 \pm 4\sqrt{3}}{2}[/tex]
Divide
[tex]x =5 \pm 2\sqrt{3}[/tex]
Hence, the equation that expresses the solution to the quadratic equation x² - 10x + 13 = 0 is [tex]x =5 \pm 2\sqrt{3}[/tex]

Three functions are given below: f(x), g(x), and h(x). Explain how to find the axis of symmetry for each function, and rank the functions based on their axis of symmetry (from smallest to largest).
f(x) g(x) h(x)
f(x) = -2(x − 4)2 + 2 g(x) = 5x2 − 10x + 7 graph of negative 1 times the quantity of x plus 2 squared, plus 2
Answer:
h(x), g(x), f(x)
Step-by-step explanation:
The axis of symmetry of a parabola is the vertical line through its vertex.
__
f(x)The equation is written in vertex form:
f(x) = a(x -h)² +k . . . . . vertex (h, k), scale factor 'a'
The vertical line through the vertex is x=h.
Your equation is ...
f(x) = -2(x -4) +2
so (h, k) = (4, 2) and the line of symmetry is x=4.
__
g(x)The given equation can be written in vertex form:
g(x) = 5x² -10x +7
g(x) = 5(x² -2x) +7
g(x) = 5(x² -2x +1) +7 -5 . . . . complete the square
g(x) = 5(x -1)² +2
so (h, k) = (1, 2) and the line of symmetry is x=1.
__
h(x)Your problem statement tells us ...
h(x) = -(x +2)² +2
so (h, k) = (-2, 2) and the line of symmetry is x=-2.
The coordinates of the vertex can also be read from the graph: (-2, 2).
__
orderThe rank of the functions is the order of {-2, 1, 4}, or h(x), g(x), f(x).
Use the quadratic formula to solve for x.
Round your answer to the nearest hundredth.

Step-by-step explanation:
The 21,500 would be the a value of the function, as it is before the parentheses. The a value of an exponential function is a constant, and it is the y-intercept of that function, meaning in a real-world application, it would be where the values start at. In this case, the 21,500 is where the price of the car starts at, i.e., the original value of the car.

Answer:
B. The equation of the linear function is y = 3x + 2
D. The rate of change of the linear function is 3.
Step-by-step explanation:
First find the slope by choosing two ordered pairs and using the slope formula:
[tex]\textsf{let}\:(x_1,y_1)=(2,8)[/tex]
[tex]\textsf{let}\:(x_2,y_2)=(3,11)[/tex]
[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{11-8}{3-2}=3[/tex]
Now use the Point-slope form of linear equation with the found slope and one of the points to create the equation of the linear function:
[tex]y-y_1=m(x-x_1)[/tex]
[tex]\implies y-8=3(x-2)[/tex]
[tex]\implies y=3x + 2[/tex]
The rate of change of a linear function is its slope.
Therefore,
B. The equation of the linear function is y = 3x + 2
D. The rate of change of the linear function is 3.
