Answer:
[tex]1 + cot^2 \theta[/tex]
Step-by-step explanation:
Given the expression;
[tex]\frac{tan^2\theta+1}{tan^2 \theta}[/tex]
Separating into partial fraction;
[tex]\frac{tan^2 \theta}{tan^2 \theta} + \frac{1}{tan^2 \theta}\\= 1 + \frac{1}{tan^2 \theta}\\\\[/tex]
Since [tex]\frac{1}{tan \theta} = cot \theta\\[/tex]
Hence the expression becomes;
[tex]1 + cot^2 \theta[/tex]

A plant costs p dollars and a bush costs b dollars. Ana buys 2 plants and 4 bushes for $42. Paola buys 7 plants and 9 bushes for $107. Write down a pair of simultaneous equations and solve them to find out the value of p and the value of b.
Answers
Answer:
2p + 4b = 42
7p + 9b = 107
p = $5
b = $8
Step-by-step explanation:
p is cost of plant, b is cost of bush
2p + 4b = 42
7p + 9b = 107
First we'll solve the first equation for p in terms of b:
2p + 4b = 42
subtract 4b from both sides
2p = -4b + 42
divide both sides by 2
p = -2b + 21
Now substitute that value in for p in the second equation, and solve for a numerical value of b:
7(-2b + 21) + 9b = 107
-14b + 147 + 9b = 107
combine like terms:
-5b = -40
b = 8
Use this to go back and solve for p:
p = -2b + 21
p = -2(8) + 21
p = -16 + 21 = 5
---------------------------
check the math:
2p + 4b = 42
2(5) + 4(8) = 10 + 32 = 42
Edgar owns 234 shares of Cawh Consolidated Bank, which he bought for $21.38 apiece. Each share pays a yearly dividend of $3.15. Edgar also owns two par value $1,000 bonds from Cawh Consolidated Bank. The bonds had a market value of 105.166 when he bought them, and pay 8.3% interest yearly. Which aspect of Edgar’s investment in Cawh Consolidated Bank offers a greater percent yield, and how much greater is it? a. The stocks have a yield 6.43 percentage points greater than that of the bonds. b. The stocks have a yield 6.84 percentage points greater than that of the bonds. c. The bonds have a yield 1.05 percentage points greater than that of the stocks. d. The bonds have a yield 9.13 percentage points higher than that of the stocks.
Answers
Answer: B. The stocks have a yield 6.84 percentage points greater than that of the bonds.
Step-by-step explanation:
Firstly, the yield for stocks will be calculated as:
= return/ investment cost
= $3.15/$ 21.38
= 0.14733395
= 14.73%
The yield for bonds will be calculated as:
= Return/Investment cost
Return = 1,000 x 8.3% = 83
Investment cost = 1,000 x 105.166/100 = 1051.66
Yield = 83/1051.66
= 0.07892284
= 7.89%
Then, the difference between the yield will be:
= 14.73% - 7.89%
= 6.84%
Therefore, the stocks have a yield 6.84 percentage points greater than that of the bonds.
Answer:
b.The stocks have a yield 6.84 percentage points greater than that of the bonds. Step-by-step explanation: got it right on edge 2022!
If x + x = 9, then x =
Answers
Answer: x = 4.5
Step-by-step explanation: First, do x + x, since they are like terms. That equals 2x. The equation is now 2x = 9. Divide both sides by 2. x = 4.5.
x + x = 9
2x = 9
÷2 ÷2
---------------------
x = 4.5
x + x = 9
4.5 + 4.5 = 9

Answer:
D. Yes; the graph passes the vertical line test.
Step-by-step explanation:
1. A and C are wrong since the number of x-values that a y-value have does not matter when it comes to functions.
2. When doing the vertical line test, it is done by drawing a vertical line (up to down) and then seeing if more than 1 point touches the line.
3. After drawing the vertical line you would see only 1 point touches the line which indicates that the graph passes the vertical line test.
4. Therefore, the answer is "D. Yes; the graph passes the vertical line test."

Step-by-step explanation:
In this case, since this equation has both sides as a perfect square, you can apply the difference of squares formula a^2 - b^2 = (a+b) (a-b)
Applying this formula and factoring it accordingly leaves us off with (5x2y3+1)(5x2y3−1).

Una empresa quiere confecionar 7²⁰ chompas. Si el 1er día confeccionada los 3/10 del total. El 2do dia los 2/9 del total, ¿cuantas chompas le falta confeccionar? Con cada paso porfavor :(
Answers
Answer:
A la empresa le faltan confeccionar 344 chompas.
Step-by-step explanation:
Dado que una empresa quiere confeccionar 720 chompas, si el 1er día confeccionaron los 3/10 del total y el 2do día los 2/9 del total, para determinar cuántas chompas le falta confeccionar se debe realizar el siguiente cálculo:
Día 1:
720 x 3/10 = X
720 x 0.3 = X
216 = X
Día 2:
720 x 2/9 = X
720 x 0.22222 = X
160 = X
720 - 216 - 160 = X
344 = X
Por lo tanto, a la empresa le faltan confeccionar 344 chompas.

We know that , tan(x+y)=(tanx + tany)/(1 - (tanx)(tany))
tan(2A+A)=(tan2A+tanA)/(1 - (tan2A)(tanA))— (1)
We know that , tan2x=2tanx/(1 - tan^2x)
So, by substituting tan2A in (1),we get,
=[2tanA/(1 - tan^2A) + tanA]/1- (2tanA/(1 - tan^2A))(tanA)]
=[2tanA+tanA - tan^3A]/[1 - tan^2A - 2tan^2A]
=[3tanA - tan^3A]/[1-3tan^2A]
Therefore, tan3A= [3tanA - tan^3A]/[1-3tan^2A]

If Arnold charges $522.00 for a 4 personal training sessions (of an hour each)
a) What is his hourly rate?
b) How much would he charge for a 3 hour session?
Answers
Answer:
Hourly rate = 130.50
3-hour session = 391.50
Step-by-step explanation:
Part 1
Step 1: Divide the given figures
522.00/4 = 130.50
Step 2: Multiply the result to the number being looked for
130.50 * 1 = 130.50
So, Arnold’s hourly rate is 130.50
Part 2
Step 1: Multiply the answer found in part one to 3
130.50 * 3 = 391.50
Therefore, Arnold’s would charge $391.50 in a 3-hour session
x+y=80
5x+8y=535
what is x and what is y
Answers
Answer:
x+y=80 i.e. 5x+5y=400 multiplying both sides by 5
now 5x+8y=535
therefore 3y=535-400=135
therefore y=135/3=45
now x=80-y=80-45=35
therefore final answer x is 35 y is 45
Answer:
x=35, y=45
Step-by-step explanation:
x+y=80=>5x+5y=400 so (5x+8y)-(5x+5y)=535-400
<=>3y=135<=>y=45=>x=80-y=80-45=35
