How can the stage manager use the constant of proportionality to find the
dimensions of any new props the director requires?
Answers
a) the constant of proportionality multiplies every actual linear dimension
b) height of a can of fruit juice is 3.85 inches high
What is Proportionality?
The term proportionality describes any relationship that is always in the same ratio.
Explanation for answer:
Since the desire is to have students look twice as tall, we expect the constant of proportionality to be [tex]\frac{1}{2}[/tex].
Instead, we're told that the stage manager is using a height of 44 inches to represent an 80-inch door.
This means their constant of proportionality is [tex]\frac{40}{80} = 0.55[/tex]
a) Any new props can be scaled by this factor (0.55) to find their height on set.
b) A 7-inch can would be scaled to [tex]7\times 0.55 = 3.85\ inches[/tex]
Question: The school's theater club is building sets that will make ordinary students look like giants. The actors need a door, a table, and a stool that will make them look almost twice as tall!

What is an exponent?
Exponent is the process of expressing large numbers in terms of powers. In other words, the exponent describes how many times a number has been multiplied by itself.
According to the zero exponent rule, any base with a zero exponent is equal to one. For instance, [tex]x^{0} = 1[/tex].
We have,
[tex]= \frac{1.25\\ * \\ 10^{-3}}{1.25 \\ * \\ 10^{-3}}[/tex]

Using the multiplication rule of fraction [tex]a\cdot \frac{b}{c}=\frac{a\:\cdot \:b}{c}[/tex]
[tex]= \frac{1.25 \ * \ 10^{-3} \ * \ 10^{3}}{1.25 \\}[/tex]

By applying the exponent rule [tex]\:a^b\cdot \:a^c=a^{b+c}[/tex] we get,

B. Jake's birdhouses cost $3 more than Liana's.
C. Llana will have a greater profit than Jake if they each sell all 50 birdhouses.
D.
Llana and Jake will have the same profit if they each sell exactly 20 birdhouses.
E. Llana and Jake each need to sell a minimum of 11 birdhouses in order to make a profit.
Answers
(A) and (E) are the true statement.
Given,
In the question:
Jake and Liana make and sell wooden birdhouses. Jake spent $150 buying supplies. He sells each birdhouse for $15. The equation P = 12x - 120 represents the profit, P, Liana earns for selling x birdhouses. Jake and Llana each made 50 birdhouses.
To find the which statement is true?
Now, According to the question:
Jake's Profit: J = 15x - 150
Liana's Profit : P = 12x - 120
(A) when x = 0, P = -120, J = -150
then, 150 - 120 = $30
So, Jake spent $30 more than Liana
So, A is true, B is wrong.
(C) when x = 50 , J = 15 x 50 - 150 = $600
P = 12 x 50 - 120 =$480
Since, 600> 480
(D) when J = P
then, 15x - 150 = 12x = 120
3x = 30
x = 10
x = 10 not equal to 20
So, D is wrong
(E) when P> -0 , and J > 0
then, 12x -120 > 0 and 15x - 150 > 0
=> x > 10
So, the minimum is 11, E is true .
Hence, Above the solution (A) and (E) are the true statement.

5x-3/x-1 what is the inverse of this
Answers
Answer:
[tex]f^{-1}(x)=\dfrac{3-x}{5-x}, \quad \{x|x\neq 5\}[/tex]
Step-by-step explanation:
Given function:
[tex]f(x)=\dfrac{5x-3}{x-1}[/tex]
As the given function is a rational function, the domain and range are restricted.
Domain: (-∞, 1) ∪ (1, ∞).Range: (-∞, 5) ∪ (5, ∞).f⁻¹(x) is the notation for the inverse of the function.
The inverse of a function is a reflection in the line y = x.
To find the inverse of the given function, swap f(x) for y:
[tex]\implies y=\dfrac{5x-3}{x-1}[/tex]
Rearrange the equation to isolate x:
[tex]\implies y(x-1)=5x-3[/tex]
[tex]\implies xy-y=5x-3[/tex]
[tex]\implies 3-y=5x-xy[/tex]
[tex]\implies 3-y=x(5-y)[/tex]
[tex]\implies x=\dfrac{3-y}{5-y}[/tex]
Swap the x for f⁻¹(x) and the y for x:
[tex]\implies f^{-1}(x)=\dfrac{3-x}{5-x}[/tex]
The range of the function is the domain of the inverse function.
Therefore, the domain of the inverse function is restricted:
Domain of f⁻¹(x): (-∞, 5) ∪ (5, ∞).a- 10 units

Given a temperature rise of 3.85 °F over 4 hours after noon, when the temperature is 85.4 °F, you want to know the change between 4 pm and 5 pm if the temperature at 5 pm is 89.25 °F.
Temperature at 4The temperature at 4 pm is the sum of the noon temperature and the change in the 4 hours after noon:
85.4 °F + 3.85 °F = 89.25 °F
Change after 4The change from 4 pm to 5 pm is the difference between the 5 pm temperature and the 4 pm temperature:

equation for the perpendicular bisector of the line segment whose endpoints
are (-9, 3) and (-3, -1).
Answers
Equation for the perpendicular bisector of the line segment is
2y = 3x +20.
A line segment that bisects another line segment at a 90° angle is known as a perpendicular bisector.
What is perpendicular bisector?A line segment that bisects another line segment at a 90° angle is known as a perpendicular bisector. In other terms, a perpendicular bisector separates a line segment into two equal halves by intersecting it at a 90° angle.
Given coordinates of the endpoints of a line segment (-9, 3) and (-3,-1).
In order to find the equation of perpendicular line, we need to find the slope between given coordinates.
Slope between (-9, 3) and (-3, -1). :
slope = [tex]\frac{-1-3}{-3+9} =\frac{-2}{3}[/tex]
Slope of the perpendicular line is reciprocal and opposite in sign.
Therefore, slope of the perpendicular line = 3/2
Now, we need to find the midpoint of the given coordinates.
[tex]Mid points : \\x= \frac{ -9-3}{2} =-6\\ y= \frac{3-1}{2} = 1\\ pint = (-6,1)[/tex]
Let us apply point-slope form of the linear equation:
y-y1 = m(x-x1)
y - 1 = 3/2 (x + 6)
2y = 3x +20
