Step-by-step explanation:
Mathematically;
csc 2 theta = 1 / sin 2 theta
Sin 2 theta = sin (theta + theta)
= 2sin theta cos theta
So therefore;
csc 2 theta = 1/2(sin theta cos theta)
= 1/2 * 1/sin theta * 1/ cos theta
1/sin theta = csc theta
1/cos theta = sec theta
Thus;
csc 2 theta = 1/2 * csc theta * sec theta
csc 2 theta = 1/2 sec theta csc theta

karen is reading the great gatsby in English class. So far, she has read 30 pages. If she reads 18 pages a day and there are 192 pages in the book, how many days will it take her to finish the book
Answers
Answer:
it will take her 9 days
Step-by-step explanation:
192- 30 = 162
162 / 18 = 9
Answer:
9 days
Step-by-step explanation:
192-30=162
162/18=9
There is 192 pages in total and if she has read 30 pages already you need to work out how much is left so you do 192-30. That would be 162 pages. It says that she reads 18 pages a day so now you need to divide 162 by 18 pages to see how many days it will take for her to finish the book. that is how the answer is 9 days.
I hope this helps
So I have a question. Its a really good question. I'm not sure you'll get it though. Okay so my question is if a train leaves a station at 12 o'clock and moves at a constant speed of 90 mph and another train leaves a different station 2000 miles away in the opposite direction at 2 o'clock traveling at 80 mph. When will both trains cross each other?
Answers
Answer:
12:42 (approximately)Step-by-step explanation:
Train 1 will travel for 2 hours before the second train leaves.
The distance at 2 o'clock is reduced by 2*90 = 180 miles and now is:
2000 - 180 = 1820 milesLet the trains spend x hours before crossing, then we have following equation for the distance:
x(90 + 80) = 1820170x = 1820x = 1820/170x = 10 120/170 = 10 12/17 hours ≈ 10 hours and 42 minutesThe trains will cross at:
2 o'clock + 10 h 42 min = 12:42The time when trains cross each other will be approximately 12:42

A bike rental charges a flat fee of $500. As well as $0.05 every mile. If you spent$10 how many miles did you take the bike for? Write and solve an equation for this problem
Answers
Answer: 100 miles.
Step-by-step explanation:
Here , Flat fee = $ 5.00
Additional charge per mile = $ 0.05
Money spent = $ 10
Formula : Total Charge = Flat fee + (Number of miles ) x (Additional charge per mile)
Let x= Number of miles
Substitute values , we get
10 = 5 + 0.05x
⇒ 0.05x= 5
⇒ x = 100
Hence, I took bike for 100 miles.

Which graph represents the function g(x) = |X + 4| + 2?
Answers
Answer:
B on edge
Step-by-step explanation:
The graph that represents the function g(x) = |x + 4| + 2 is graph A.
Option A is the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The function g(x) = |x + 4| + 2 is a transformation of the absolute value function f(x) = |x|.
The absolute value function has a V-shaped graph that passes through the origin with a slope of 1 on both sides.
When a constant is added to the absolute value function, it shifts the graph vertically.
In this case, the constant 4 is added inside the absolute value, which shifts the graph horizontally to the left by 4 units.
Next, the constant 2 is added to the result of the previous operation, which shifts the graph vertically upwards by 2 units.
The graph of g(x) = |x + 4| + 2 is a V-shaped graph that has been shifted 4 units to the left and 2 units upwards, as shown below:
The vertex of the V-shape is at (-4, 2), where the absolute value function crosses the x-axis.
The slope of the graph on both sides of the vertex is 1.
Thus,
The graph that represents the function g(x) = |x + 4| + 2 is graph A.

A right triangle is shown. The legs are labeled 6 and 9. A right angle is labeled in between them.
Cade's Work Tyce's Work
a2 + b2 = c2 a2 + b2 = c2
62 + b2 = 92 62 + 92 = c2
36 + b2 = 81 36 + 81 = c2
b2 = 45 117 = c2
√b2 = √45 √117 = √c2
b ≈ 6.71 10.82 ≈ c
Is either of them correct? Explain reasoning

Answer:
Cade is not right because in his second step he did 6^2 + b^2 = 9^2. In this problem, you are trying to find the hypotenuse, which is c^2. B^2 is the other leg, but this problem has given the lengths of both the legs. If he did it correct the second step would look like 6^2 + 9^2 = c^2.
Tyce is right since he followed all the steps and did the math correctly :)

Answer:
The vehicle can travel 12 miles per gallon of gasoline
Step-by-step explanation:
Proportions
A vehicle uses 1 1/8 gallons of gasoline to travel 13 1/2 miles.
It's required to find the rate of miles per gallon of gasoline consumption of the vehicle.
First, we convert all the mixed fractions to improper fractions:
[tex]1\frac{1}{8}=1+\frac{1}{8}=\frac{9}{8}[/tex]
[tex]13\frac{1}{2}=13+\frac{1}{2}=\frac{27}{2}[/tex]
The rate of consumption is:
[tex]\displaystyle \frac{\frac{27}{2}}{\frac{9}{8}}[/tex]
Operating:
[tex]\displaystyle \frac{\frac{27}{2}}{\frac{9}{8}}=\frac{27}{2}\cdot\frac{8}{9}=12[/tex]
The vehicle can travel 12 miles per gallon of gasoline

Latoya is saving money at a constant rate to buy a new computer. The table below shows the amount of money that Latoya still needs to purchase the computer.
How many dollars is Latoya saving each week?
Answers
Answer:
630-450= 180
there were three weeks between these two amounts
180/3 = 60
450-330= 120
there were two weeks between these two amounts
120/2 = 60
330-210 = 120
again two weeks between amounts
120/2 = 60
It can now be said that LaToya is saving $60 per week
