The radius is 33 feet. The height is really a radius. The diameter consists of 2*r
r = diameter / 2
diameter = 66 feet
r = 66 /2 = 33
So you have 2 ways of finding the radius.
Solution
Area of a full circle = pi r^2
Area of a full circle = pi * 33^2
Area of a full circle = 1089 pi
Area of a semicircle = area of a full circle / 2
Area of a semicircle = 1089 * pi /2
Area of a semicircle = 544.5 * pi
Answer
Exact answer in terms of pi is 544.5 * pi
Approximate answer using 3.14 for pi = 3.14*544.5 = 1709.73

What are the domain and the range of a function?The domain of a function is the set that contains all the values of the input.The range of a function is the set that contains all the values of the output.In this problem, neither function has any impediment, such as an even root or denominator, hence the domain is all real numbers. As for the range, a linear function assumes all real values, while a concave up quadratic function assumes values of the vertex, in this case y = 5, and greater, hence the range of the second function is [tex]y \geq 5[/tex].

The question is :
Danielle reflects shape S in the line x = - 1 , and then reflects the new shape in the line y = 2
Zachary reflects shape S in the line y = 2 , and then reflects the new shape in the line x = - 1
Work out the coordinates of the vertex that A maps to after
a) Danielle's two reflections.
b) Zachary's two reflections.
.
The coordinates of the vertex that A maps to after Daniel's reflections are (3, 4) and the coordinates of the vertex that A maps to after Zachary's reflections are (3, 2)
How to determine the coordinates of the vertex that A maps to after the two reflections?From the given figure, the coordinate of the vertex A is represented as:
A = (-5, 2)
The coordinates of the vertex that A maps to after Daniel's reflections
The rule of reflection across the line x = -1 is
(x, y) ⇒ (-x - 2, y)
So, we have:
A' = (5 - 2, 2)
Evaluate the difference
A' = (3, 2)
The rule of reflection across the line y = 2 is
(x, y) ⇒ (x, -y + 4)
So, we have:
A'' = (3, -2 + 4)

A'' = (3, 4)
Hence, the coordinates of the vertex that A maps to after Daniel's reflections are (3, 4)
The coordinates of the vertex that A maps to after Zachary's reflections
The rule of reflection across the line y = 2 is
(x, y) ⇒ (x, -y + 4)

If a union member does not pay their union dues, they will not be able to
Answer:
The ¨mandatory dues¨ asked by the unions are not much (practically none), since it´s a voluntary system implemented, normally all the members pay a ¨agency fee¨ but not more than that, this changes depending on the personal involvement with the union.
a natural person can refuse the membership at any moment, without issues, and this way avoid any kind of activity with the union, including contributing with money (dues) or duties.
However, when this happens, the person it´s restricted to certain activities like participate in union elections, general or important meetings, and the contribution in the bargain for the collective elections is banned as well, these as main aspects to highlight.
If one doesn't pay they union dues, they will not be able to participate in collective bargaining with owners.
Only the real representatives of the union could participate in collective bargaining with owner (in which they could negotiate the new term of the salary with the owner). Without paying their dues, they're still haven't been acknowledged as the member of union.
Hope this helps have a great day!

You are investigating having business cards printed for your new game store. A local printing company charges $250 for the cardboard used and an hourly rate for labour of $40.

of the cards, C.
b. You have budgeted $1000 for the printing job. How many hours of labour can you afford? Give
your answer to the nearest minute.
c. The company estimates that it can print 1000 cards per hour of labour. How many cards will you
get printed with your current budget?
d. An alternative to printing is photocopying. The company charges 15 cents per side for the first 10 000 cards and then 10 cents per side for the remaining cards. Which is the cheaper option for 18 750 single-sided cards and by how much?
Answer:
See below.
Step-by-step explanation:
a. If h is the number of hours of labour required to print the cards, construct an equation for the cost of the cards, C.
C = $250 + ($40/hr)*h
b. You have budgeted $1000 for the printing job. How many hours of labour can you afford? Give your answer to the nearest minute.
$1000 = $250 + ($40/hr)*h
($40/hr)*h = $750
h = 18.75 hours
(18.75 hours)(60 min/hr) = 1125 minutes
c. The company estimates that it can print 1000 cards per hour of labour. How many cards will you get printed with your current budget?
(18.75 hr)*(1000 cards/hr) = 18,750 cards
d. An alternative to printing is photocopying. The company charges 15 cents per side for the first 10 000 cards and then 10 cents per side for the remaining cards. Which is the cheaper option for 18 750 single-sided cards and by how much?
Photocopy Cost for the first 1000 single-sided cards is:
(1000 cards)*($0.15) = $150
Photocopy Cost for the final 17,750 single-sided cards is:
(17,750)*($0.10) = $1,775
Totoal photocopy cost for 18,750 single-sided cards is $1,925. [1775+150]
The cheapest option for 18,750 cards is printing: $1,000
Printing is (1,925 - 1000) $925 cheaper than photocopying.

For the graph y = 1 find the slope of a line that is perpendicular to it and the slope of a line parallel to it. Explain your answer with two or more sentences.
The slope of the parallel line is 0 and the slope of the perpendicular line is undefined
How to determine the slope?The equation is given as:
y = 1
A linear equation is represented as:
y = mx + c
Where:
m represents the slope
By comparison, we have:
m = 0
The slope of the parallel line is:
Slope = m
This gives
Slope = 0
The slope of the perpendicular line is:
Slope =-1/m
This gives
Slope = -1/0
Slope = undefined

The taxi fare for the first two miles is $5 and for each additional mile the fare increases by $ 2. What is the taxi fare for a journey of n miles in dollars?
The taxi fare for a journey of n miles in dollars is 1 + 2n
What are linear equations?Linear equations are equations that have constant average rates of change, slope or gradient
How to determine the equation of the system?The given parameters about the taxi fares are given as
First two miles = $5
Additional mile = Increment of $2
Let the number of miles be n
So, we have:
2 miles = $5
Additional miles = (n - 2) * 2
Add the above expressions
5 + (n - 2)* 2
Represent the value with f(n)
So, we have:
f(n) = 5 + (n - 2)* 2
Expand the bracket
f(n) = 5 + 2n - 4
Collect the like terms
f(n) = 5 - 4+ 2n
Evaluate the like terns
f(n) = 1 + 2n
Hence, the taxi fare for a journey of n miles in dollars is 1 + 2n
So, the complete parameters are:
First two miles = $5
Additional mile = Increment of $2

Find angle V
(2x +29)= (10x-27)
Answer:
137
Step-by-step explanation:
VYXW is a parallelogram.
The opposite angles of a parallelogram are congruent, meaning their angle measurements are equal.
Following this information we can write an equation to find the value of x:
10x - 27 = 2x + 29 transfer like terms to the same side of the equation
10x - 2x = 29 + 27 add/subtract
8x = 56 divide both sides by 8
x = 7 replace x with 7 to find the given angle measures
now, the consecutive angles in a parallelogram are supplementary meaning their sum is equal to 180
m<V + m<W = 180
m<V + 2*7 + 29 = 180
m<V + 43 = 180 subtract 43 from both sides
m<V = 137

y = 75x + 50 ------(eq 2)
How to Solve Simultaneous Equations?A) Let the total cost of the cat tree be y
Let each additional piece added be x.
Since basic tree is $100 and each additional platform costs $50, then we can say that;
