(csc x - 1) (csc x + 1)
victus00 [196]
<h2>Explanation:</h2>

Here we have the following expression:

(csc x - 1) (csc x + 1)

So we need to extend this. Remember that the difference of squares tells us:

(a-b)(a+b)=a^2-b^2

So here:

a=cscx \\ \\ b=1

Thus:

(csc x - 1) (csc x + 1)=csc^2x-1 \\ \\ \\ But: \\ \\ cscx=\frac{1}{sinx} \\ \\ \\ Then: \\ \\ csc^2x-1=\frac{1}{sin^2x}-1=\frac{1-sin^2x}{sin^2x}=\frac{cos^2x}{sin^2x}=cot^2x \\ \\ \\ Finally: \\ \\ \boxed{(csc x - 1) (csc x + 1)=cot^2x}

A population of 110,000 grows 5% per year for 14 years. How much will the population be after 14 years?
Fantom [35]

Answer:

Since it is growing at 5% per year, at the end of each year the population will be 1.05 times what is was at the start of the year.

 

Start with 110,000 and multiply by 1.05 a total of 16 times to get the population at the end of 16 years.

 

P = 110,000 x 1.0316 ≅ 176,518

What is the total surface area of the drawing?
Soloha48 [4]

Total surface area equals area of 5 rectangular faces + 2 pentagonal faces


Area of 5 rectangular faces

=5 \times 6 \times 9 km^2


=270 km^2


Area of 2 pentagonal faces can be found by drawing 5 isosceles triangles with height as shown in the diagram and multiply the result by 2.


=5 \times \frac{1}{2} \times 9 \times 6.2 \times 2km^2



=279km^2



The toatal surface area is



=270+279=549 km^2


The correct answer is A

Name the algebraic property demonstrated in the example below:
Masja [62]
Answer: Choice D) Commutative Property of Multiplication

-------------------------------------

The commutative property of multiplication states that a*b = b*a. In other words, it doesn't matter how you multiply two numbers. The order isn't important. 

For example, 2*3 = 3*2 = 6

So that's why we're able to do x*y = y*x
Furthermore, 
x*y*z = y*x*z
Only the x and y swap places
