(please help me answer these 3 questions, picture attached)
Questions:
1. what is the area of the whole rectangle?
( area = length * width )
2. what is the area of the shaded rectangle?
3. what is the area of the unshaded part of the rectangle? (area of the whole rectangle - area of the shaded part)
Answer: See below
Step-by-step explanation:
1) For the first question, we have to multiply the width by the length to find the area of the whole rectangle:
(4x-4)(x+1)= 4x^2 -4
2) For the second question, we have to multiply the width by the length to find the area of the shaded area in the rectangle:
(2x+2)(x-1)= 2x^2-2
3) The total area of the unshaded part of the whole triangle equals the area of the whole rectangle minus the shaded area:
4x^2-4 - 2x^2 -2 = 2x^2 - 6
in college basketball, some teams get most of their points from just one player, and other teams are more balanced in scoring. consider the following facts about the scoring distributions for some ncaa division i basketball teams. each team has 121212 players. at baylor university, there are 666 players who each score 121212 points per game, and there are 666 players who each score 000 points per game. at the university of maryland, 111 player scores 585858 points per game, 111 player scores 141414 points per game, and the rest of the players score 000 points per game. at dartmouth college, 444 players score 555 points per game, 444 players score 666 points per game, and 444 players score 777 points per game.
At Maryland, the mean number of points per player per game is greater than the median number of points per player per game. The mean number of points per player per game is the same at all 3 schools.
Given that in Baylor's University that there are 6 players who each score 12 points per game, and 6 players who each score 0 points per game.
The scores are 0, 0, 0, 0, 0, 0, 12, 12, 12, 12, 12, 12.
Mean = Sum/Count = 72/12 = 6.
Median is the average between the nth and (n+1)th term.
(0+ 12)/2 = 6
In Maryland university 1 player scores 58 points per game, 1 player scores 14 points per game, and the rest of the 10 score 0 points per game,
58, 14, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0
Mean = Sum/Count = 72/12 = 6.
Median is 0
In Dartmouth, university, 4 players score 5 points per game, 4 players score 6 points per game, 4 players score 7 points per game.
The scores are
5, 5, 5, 5, 6, 6, 6, 6, 7, 7, 7, 7
Mean = Sum/Count = 72/12 = 6
Median =(6+6)/2= 6

Find the focus and the directrix for the parabola with the given equation.
Answer:
[tex]\mathrm{Focus:\;\;} \left(-\frac{5}{3},\:2\right)[/tex]
[tex]\mathrm{Directrix:\;\;}x=-\frac{1}{3}[/tex]
Step-by-step explanation:
The standard equation for a parabola is
[tex]4p\left(x-h\right)=\left(y-k\right)^2[/tex]
with vertex at (h, k) and a focal length of |p|
[tex]\mathrm{Rewrite}\:x=-\frac{3}{8}\left(y-2\right)^2-1\:\mathrm{in\:the\:standard\:form}[/tex]:
[tex]\mathrm{Add\:}1\mathrm{\:to\:both\:sides}[/tex]
[tex]x+1=-\frac{3}{8}\left(y-2\right)^2-1+1[/tex] or
[tex]x+1=-\frac{3}{8}\left(y-2\right)^2[/tex]
[tex]\mathrm{Divide\:both\:sides\:by\:}-\frac{3}{8}[/tex]
[tex]\frac{x+1}{-\frac{3}{8}}=\frac{-\frac{3}{8}\left(y-2\right)^2}{-\frac{3}{8}}[/tex]
[tex]\mathrm{Simplify}[/tex]
[tex]-\frac{8x}{3}-\frac{8}{3}=\left(y-2\right)^2[/tex]
[tex]\mathrm{Factor\:}-\frac{8}{3}[/tex]
[tex]\left(-\frac{8}{3}\right)\left(x+\frac{-\frac{8}{3}}{-\frac{8}{3}}\right)=\left(y-2\right)^2[/tex]
[tex]\mathrm{Simplify}[/tex]
[tex]\left(-\frac{8}{3}\right)\left(x+1\right)=\left(y-2\right)^2[/tex]
[tex]\mathrm{Factor\:}4[/tex]
[tex]4\cdot \frac{-\frac{8}{3}}{4}\left(x+1\right)=\left(y-2\right)^2[/tex]
[tex]\mathrm{Simplify}[/tex]
[tex]4\left(-\frac{2}{3}\right)\left(x+1\right)=\left(y-2\right)^2[/tex]
[tex]\mathrm{We\; can\; rewrite\:this\;as}[/tex]
[tex]4\left(-\frac{2}{3}\right)\left(x-\left(-1\right)\right)=\left(y-2\right)^2[/tex]
Comparing this with the standard form we get
[tex]\left(h,\:k\right)=\left(-1,\:2\right)[/tex]
[tex]\:p=-\frac{2}{3}[/tex]
The parabola is symmetric around the x-axis.
The focus lies a distance [tex]p[/tex] from the center [tex]\left(-1,\:2\right)[/tex] along the x axis
So focus is at
[tex]\left(-1+p,\:2\right)[/tex] [tex]=\left(-1+\left(-\frac{2}{3}\right),\:2\right)[/tex] [tex]=\bold{ \left(-\frac{5}{3},\:2\right)}[/tex]
The parabola is symmetric around the x-axis and so the directrix is a line parallel to the y-axis at a distance -p from the center
[tex]x=-1-p[/tex]
[tex]x=-1-\left(-\frac{2}{3}\right) = \bold{-\frac{1}{3}}[/tex]
a translation along the directed line segment \overline{nb} nb start overline, n, b, end overline, then a reflection over the vertical line through point bbb.
A translation along the directed line segment NB then a reflection over the vertical line about B so sequence A is correct therefore option (A) will be correct.
What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
Reflection is a mirror image of a graph about any axis.
If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).
Given the triangle MNO and ABC
Now,
If we translate MNO along the directed line segment NB and reflect over B then M will coincide with A and N with B and O with C.
In sequence B if we reflect on MO then M will not coincide with A and it will not form a triangle ABC.
Hence "A translation along the directed line segment NB then a reflection over the vertical line about B".

Number of ways to distribute 5 dollar bills among three children = 21
and
Number of ways to distribute 5 dollar bills such that each child gets at least one dollar = 6
What is permutations and combinations?A permutation is an orderly arrangement of the items or numbers. Combinations are a means to choose items or numbers from a collection or set of items without regard for the items' chronological sequence.Given:
Number of 1 dollar bills = 5Number of children = 3To find: (A) number of ways to distribute the dollar bills among the children
(B) number of ways to do the same if each child gets at least a dollar.
Finding:
By using the formula: [tex]\binom{n+r-1}{r-1}[/tex],
Number of ways to distribute 5 dollar bills among three children = [tex]\binom{5+3-1}{3-1} = \binom{7}{2}= \frac{7\times6}{2}[/tex] = 21 ways.

in a certain clothing store, the ratio of the number of full-time employees to the number of employees who are not full-time is 1 to 4. if 5 more full-time employees were hired, the ratio would be 2 to 3. how many employees are employed by the store?
Answer: Total number of employees are employed by the store = 15 employees.
Step-by-step explanation:
The ratio of Full time employees to Not Full time employees would be 1 to 4.
Let, Full time employees F =1
Not Full time employees N =4
We can write:
F/N = ¼
Cross multiply to get:
N=4F
If 5 more Full time employees were hired, then the ratio would be 2 to 3.
This would be mean there are no (F+5) Full time employees.
Also there are still Not Full time employees.
We can write:
(F+5) / N = 2/3
Cross multiply to get:
3(F+5) =2N
Expand to get:
3F+15=2N
Replace N with 4F to get:
3F+15=2(4F)
Solve to get:
3F+15=8F
15=8F-3F
15=5F
F=3
So, there are presently 3 Full time employees.
How many employees does the store have?
Since F=3,
we can use the equation N=4F
To help find the value of N Replace F with 3 to get:
N = 4(3)
Solve to get:
N=12
So, Full time employees F=3
Not Full time employees N=12
Then, Total number of employees = F+N
= 3+12
= 15.
Hence, Total number of employees = 15 employees.
