Answers
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
cosec x = [tex]\frac{1}{sinx}[/tex] , cot x = [tex]\frac{cosx}{sinx}[/tex]
Consider the left side
[tex]\frac{(1+cosA)^2-(1-cosA)^2}{sin^2A}[/tex] ← expand and simplify numerator
= [tex]\frac{1+2cosA+cos^2A-(1-2cosA+cos^2A}{sin^2A}[/tex]
= [tex]\frac{1+2cosA+cos^2A-1+2cosA-cos^2A}{sin^2A}[/tex]
= [tex]\frac{4cosA}{sin^2A}[/tex]
= 4 × [tex]\frac{1}{sinA}[/tex] × [tex]\frac{cosA}{sinA}[/tex]
= 4cosecAcotA
= right side, thus proven

Stephanie took a science exam that had two parts. Part 1: She got 16 questions correct, which was 45 of the number of part 1 questions. Part 2: She got 16 questions correct, which was 23 of the number of part 2 questions. What was the total number of questions on Stephanie's exam? 32 40 44 48
Answers
Answer:
44
Step-by-step explanation:
Let x and y be the total number of questions in part 1 and part 2 exams respectively.
For part 1:
Number of correct question = 4/5 of the total number of question in part 1
[tex]\Rightarrow 16=\frac{4}{5}\times x[/tex]
[tex]\Rightarrow x=20[/tex]
For part 2:
Number of corrected question = 2/3 of total number of question in part 2
[tex]\Rightarrow 16=\frac{2}{3}\times x[/tex]
[tex]\Rightarrow x=24[/tex]
So, the total umbers of the questions on Stephanie's exam
=x+y
=20+24
=44
Hence, the total umbers of the questions on Stephanie's exam was 44.
Ernie earned $121.50 more than Kaylin. Tria earned $35 less than 3 times the amount Kaylin earned. Ernie, Tria, and Kaylin earned $579 in all. How much did Tria earn?
$98.50
$220.00
$260.50
$330.50
Answers
x - Ernie, y - Kaylin, z - Tria
x = y + 121.50
z = 3y - 35
x + y + z = 579
-------------------------
z = 3 y - 35 => - 3 y + z = -35
y + 121.50 + y + z = 579
---------------------------------
- 3 y + z = - 35 / · ( -1 )
2 y + z = 457.50 (we will use the elimination method)
---------------------------------
3 y - z = 35
2 y + z = 457.50
----------------------
5 y = 492.5, y = 492.5 : 5 = 98.5
z = 3 · 98.5 - 35
z = 260.5
Tria earned $260.5
Step by step explanation
Let "x" be the amount earned by Ernie
Let "y" be the amount earned by Kaylin
Let "z” be the amount earned by Tria
Now let’s form the equations
x=y + 121.50 (1)
z=3y- 35 (2)
x + y + 2= 579 (3)
Now plug in x = y + 121.50, in the third equation.
y + 121.50 + y + z =579
2y + z = 457.50
From the second equation 3y - z = 35
2y + z =457.50
3y - z = 35
5y = 492.5
Dividing both sides by 5 we get
y = 98.50
Now let’s find how much Tria earned.
z = 3*98.5 - 35
z = $260.50

Write your final answer as a simplified fraction.
Answers
Answer:
Number of drummers in original ensemble [tex]=3[/tex]
Number of flutists in original ensemble [tex]=21[/tex]
Step-by-step explanation:
The ratio of flutists to drummers is [tex]7:1[/tex]
Let number of flutists and drummers be [tex]7x[/tex] and [tex]x[/tex].
As 2 drummers join the group and 6 flutists quit,
Number of drummers = [tex]x+2[/tex]
Number of flutists = [tex]7x-6[/tex]
New ratio of flutists to drummers = [tex]3:1[/tex]
So,
[tex]\frac{7x-6}{x+2}=\frac{3}{1}\\ 7x-6=3(x+2)\\7x-6=3x+6\\7x-3x=6+6\\4x=12\\x=3[/tex]
So,
Number of drummers in original ensemble [tex]=x=3[/tex]
Number of flutists in original ensemble [tex]=7x=7(3)=21[/tex]

how do you write y-2=-1/3(x-7)
Answers
Answer:
y= -1/3 + 13/3
Step-by-step explanation:
y-2=-1/3(x-7)
Use the distributive property to simplify the right side of the equation
y-2=(-1/3 * x) + (-1/3 * -7)
y-2=-1/3x + 7/3
Add 2 to both sides get the y by itself. 2 can be expressed as 6/3
(y-2) + 2=(-1/3x + 7/3) + 6/3
y= -1/3x + 13/3
when a figure translated, reflected, or rotated, what’s the same about the original figure and it’s image? what’s different
Answers
Answer:
The size of the figure is still the same, but the positioning on the coordinate grid is different.
Step-by-step explanation:
The size of a figure remains constant when it is translated, reflected, or rotated, but its location on the coordinate grid changes.
What is reflection?A reflection is a type of transformation that involves flipping a shape, known as the preimage, across a line, known as the line of reflection, to produce a new shape (called the image). You can picture what would happen if you turned the form across the line to graph a reflection. The reflection equation of the new reflected graph will be y=f(x), y = f (x) given an equation, y= -f(x), y = -f (x). In other words, the function is just multiplied by 1, which results in a curve that crosses the x-axis.The size of a figure remains constant when it is translated, reflected, or rotated, but its location on the coordinate grid changes.As, it is stated in the description that the size of a figure remains constant when it is translated, reflected, or rotated, but its location on the coordinate grid changes.
Therefore, the size of a figure remains constant when it is translated, reflected, or rotated, but its location on the coordinate grid changes.

which two points lie on a line with a slope closest to zero ?
Answers
Answer:
Point N and point K
Step-by-step explanation:
The steeper a line is in the graph, the greater the value of the slope of the line would be, and also, the farther it would be from 0. On the other hand, the more gentle and less sloppy a line is, the smaller the value of the slope is, and also, the closer it is to 0.
From the graph given, there are possible set of points in a line that have a gentle line slope.
The first is, points N and K. The slope of this line is ⅑.
The second is, points P and L. The slope of this line is ⅙.
From the two above lines, the one with a slope closest to 0 is the line that runs through points N and K. ⅑ is closer to 0 than ⅙.

Rubi works at a party-planing company and makes $7.50 per hour. Her weekly paycheck also inclides a $5 bonus for every party she schedules. Her $265 paycheck last week was for 30 hours. How many parties did she schedule? Explain how you found you're answer.
Answers
Answer:
8 parties
Step-by-step explanation:
First, find how much of her paycheck was from working 30 hours:
7.50(30)
= 225
Then, subtract this from 265, to find how much money was from bonuses:
265 - 225
= 40
To find how many parties she scheduled, divide 40 by 5, since each party she schedules gives her a $5 bonus:
40/5
= 8
So, she scheduled 8 parties

Rachel and four friends were going to the movies. Each ticket cost $11 and then they bought 2 popcorns at $3.75 each, and they each bought their own soda at $2.75 each. How much money did they spend total for their trip to the movies? If they decide to split the bill, how much will they each pay?
Answers
Answer:
Total amount spent [tex]=\$73.5[/tex]
If they decide to split the bill, amount paid by each of the person [tex]=\$15.25[/tex]
Step-by-step explanation:
Cost of each movie ticket = $11
Cost of 5 tickets = 5(11)= 55
Cost of each packet of popcorns = $3.75
Cost of two packets of popcorns = $2(3.75) = $7.5
Cost of each soda = $2.75
Cost of five sodas = $5(2.75) = $13.75
Total number of persons (Rachel and four friends) = 5
Total amount spent [tex]=11(5)+2(3.75)+5(2.75)=55+7.5+13.75=\$76.25[/tex]
If they decide to split the bill, amount paid by each of the person = [tex]\frac{76.25}{5}=\$15.25[/tex]

a 21-ounce box of cereal costs $3.87.what is the unit price of the cereal?
Answers
Answer:
$0.18 per ounce
Step-by-step explanation:
$3.87/21=0.1842857....
Round to the nearest $0.01
1 ounce box cost $0.182.
What is Unitary method?It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Steps to Use Unitary MethodFirst, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.
Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.
Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.
Given:
21-ounce box of cereal costs $3.87
So, 1 ounce box cost= 3.84 / 21
= $0.182
Hence, 1 ounce box cost $0.182.
