Multiple Choice:
- Rationalize the denominator
- Convert the bottom of the LHS using an identity
- Factor the RHS
- Convert tan^2(theta) + 1 of the RHS using an identity
- Find common denominators for RHS
- Cancel the 1s on LHS
Answers
Answer:
(1+cos(theta))/(1-sin^2(theta))=sec(theta)+tan^2(theta)+1
(1+cos(theta))/cos^2(theta)=sec(theta)+sec^2(theta)-1+1
(1-cos(theta))/cos^2(theta)=1/cos(theta)+1/cos^2(theta)
1-cos(theta)=cos(theta)+1
2cos(theta)=0
cos(theta)=0
theta=pi/2 and 3pi/2
I don't fully understand your question but it's quite easy to solve. As shown above, option (2) is good and you can factor the RHS but I would find it rather trivial when you can multiply both sides by cos^2(theta) just as easily. I hope this helps you.

So far this year, the average monthly revenue at the Somerville Times is $72,165. That is 25% less than the monthly average was last year. What was the average last year?
Answers
Answer:
The average last year was $96,220.
Step-by-step explanation:
From the information provided, you know that the average monthly revenue at the Somerville Times represents 75% of last year's monthly average and you can use a rule of three to find the value that represents 100%:
72,165 → 75%
x ← 100%
x=(72,165*100)/75
x=96,220
According to this, the answer is that the average last year was $96,220.
Ms. Geetha said that 60 of her total students will compete in the Math Olympics. If 60 is 20% of her students, how many total students does she have?
Answers
Answer:
300 students
Step-by-step explanation:
There are two ways to solve this question.
Way Number 160 is 20% of the total students
20÷100= 0.2
60÷0.2=300
Therefore there are 300 students
Way Number 260 is 20% of the total students
60/20 = x/100
x= 60*100÷20
x= 6000÷20
x= 300
Therefore there are 300 students.
This table represents the number of inches, n, a plant grows after m, months in a new pot.
When graphed, all of the points in the table lie on the same line.
What is the slope and y-intercept of the line?

slope=45, y-intercept=−1.6
slope=−45, y-intercept=−1.6
slope=54, y-intercept = 2
Months, m Plant height in inches, n
0 2
2 4.5
4 7
6 9.5
Answers
Answer: Slope = 5/4
y-intercept = 2
Step-by-step explanation:
We have the table:
Months, m Plant height in inches, n
0 2
2 4.5
4 7
6 9.5
We want a linear relationship to represent this table.
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
In this case we can select any pair of points, for example, i will choose the first two:
(0, 2) and (2, 4.5)
Then the slope is:
a = (4.5 - 2)/(2 - 0) = (2.5/2) = 1.25 = 5/4
Then our line can be written as:
y = (5/4)*x + b
To find the value of b, we can replace the values of any of the points in the equation, for example, i will use the point (0, 2) or x = 0, y = 2.
2 = (5/4)*0 + b
2 = b
Then our equation is:
y = (5/4)*x + 2.
Slope = 5/4
y-intercept = 2

Answer:
The answer is 3.7
Step-by-step explanation:
Use cross multiplication to set up the equation then simplify,
17y = 63
y = 63/17
y = 3.705
Round to the nearest tenth.
Solution is y = 3.07
Good luck!
Answer:
≈3.71
Step-by-step explanation:
To get from 17 to 9, you would divide by 17 and then multiply by 9, so in order to find y, you would multiply 7 by 9/17:
7 * 9/17
= 63/17
Now, you just have to simplify. That could be written as 3 12/17 if you turn it into a proper fraction, or if you turn it into a decimal, you would get about 3.71 (rounding to the tenths).

Jim is baking chocolate chip muffins. He has a total of LaTeX: 7\frac{1}{3}7 1 3 cups of chocolate chips. If each batch of muffins uses LaTeX: \frac{2}{3}2 3 of a cup of chocolate chips, enter the most number of batches of muffins Jim can bake.
Answers
Answer:
Step-by-step explanation:
Total cups of chocolate available = 7 1/3 cups
each batch uses 2/3 of a cup of chocolate
To get the number of batches of muffin Jim can bake, we will use the equality postulate.
1 batch = 2/3 cup of a chocolate
x batch = 7 1/3 cups of chocolate
Cross multiply
2/3 x = 7 1/3
2/3 x = 22/3
cross multiply
2x * 3 = 3 * 22
6x = 66
x = 66/6
x = 11
Hence Jim can bake at most 11 batches of muffins

-3(2x-3)=-6+9 How do you solve?
Answers
Answer:
Step-by-step explanation:
do u have to like determine if its true or not or solve the question?
-3(2x-3)= -6+9
you need to use distributive property and multiply -3 into 2x and -3:
-6x+9= -6+9
now you should simply the right side by adding 9 to -6:
-6x+9=3
then you need to subtract 9 from both sides in order to isolate the x term:
-6x= -6
then you divide both sides by -6 in order to get x by itself:

Juan has a piano recital next month. Last week he practiced for 12 hours in the morning and 14 hours in the afternoon. Each practice session is 3 hours long. How many full practices did Juan complete
Answers
Answer:
8 full practice
Step-by-step explanation:
Given that :
Morning Practice hours Total = 12 hours
Afternoon practice hours total = 14 hours
practice length = 3 hours
Hence, Number of full practices attended :
practice hours / practice length
Morning : 12 / 3 = 4 practice sessions
Afternoon = 14 / 3 = 4.666 sessions
Hence, number of full practice completed = 4 + 4 = 8

if triangle GHI is equilateral and JHK is isosceles, what is the measure of JHK
Answers
Answer:
The measure of JHK is 25 degrees
Step-by-step explanation:
If GHI is equilateral, it means each of the angles are equal to 60 degrees
Thus;
7x - 31 = 60
7x = 60 + 31
7x = 91
x = 91/7
x = 13 degrees
The measure of JHK IS x + 12
simply insert the value of x here
Angle JHK = 13 + 12
Angle JHK is 25 degrees
Answer: 25
