For |x| < 1, we have

[tex]1+x+x^2+\cdots=\displaystyle\sum_{n\ge0}x^n=\frac1{1-x}[/tex]

We have |sin(x)| ≤ 1, with equality when x = ± π/2. For either of these, the right side of the equation does not converge, since it's either an infinite sum of 1s or an infinite alternating sum of 1 and -1.

So for |sin(x)| < 1, we have

[tex]\sin(x)+\sin^2(x)+\sin^3(x)+\cdots=\dfrac1{1-\sin(x)}-1=\dfrac{\sin(x)}{1-\sin(x)}[/tex]

so the equation is equivalent to

[tex]\dfrac{\sin(x^2-1)}{1-\sin(x^2-1)}=\dfrac{\sin(x)}{1-\sin(x)}[/tex]

One obvious set of solutions occurs when x = x² - 1 :

x² - x - 1 = 0   →   x = (1 ± √(5))/2

i.e. the golden ratio φ ≈ 1.618 and 1 - φ ≈ 0.618.

Answer:

  B = (-4, 5)

Step-by-step explanation:

Reflection over the origin changes the signs of the coordinates.

  (x, y) ⇒ (-x, -y)

  (4, -5) ⇒ (-4, 5)

Point B is (-4, 5).

Answer:

Step-by-step explanation:

P x 20/100 x 4=240

1/5 x 4p =240

   4/5p x5=240 x 5

        4p/4=1200/4

             p=300

We need I = prt.

240 = p(0.20)(4)

240/[(0.20)(4)] = p

Use your calculator to calculate the left side.

Look :

[tex] - 5 + 3 = - 2[/tex]

[tex] - 5 \times 3 = - 15[/tex]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Answer:

-5 and 3

Step-by-step explanation:

because -5 + 3 = -2 and -5 X 3 = -15.

-5 is bigger in -5 + 3 so your answer would be negative.

and for the multiplication on use the sleeping dog - - + you have a negative and a positive so the answer would be negative.

Answer:

165 customers spent more than $500.

Step-by-step explanation:

If you ment to put $500 for both, then you have to multiply 300 by 55%. This will give you 55% of 300 which is the amount of people that spent more than $500. You multiply them to get your answer.

Answer:

1.5mph

Step-by-step explanation:

Given parameters:

Distance sailed  = [tex]\frac{3}{8}[/tex]miles

Time taken  = [tex]\frac{1}{4}[/tex]hr

Unknown:

 Unit rate of sail in miles hour = ?

Solution:

This is also the speed of the sail. It is the distance divided by time taken.

 Speed  = [tex]\frac{distance}{time}[/tex]  

 Speed  = [tex]\frac{\frac{3}{8} }{\frac{1}{4} }[/tex]  

 Speed  = [tex]\frac{3}{8}[/tex]  x 4 = 1.5mph

Answer:

I used the y=Mx+b equation because it has a good job showing each of the elements in the equation.

Step-by-step explanation:

The slope is -2/3 so if you add it to (5,1) it would be (3,4) as you just add three and subtract to to the point. I’m going to use for this equation as it is more simple and it gives a good job showing what each element is in the equation. M is the slope, so now we have y= -2/3x +b. To find b, substitute x and y for a point on this line which I will use the point (3,4) for. Now, multiply -2/3 by 3 and you will get -2 after. Now you have 4=-2+b which the answer would be 6.

This is just an example of finding the equation, which form I used, and why.

Answer:

y=6

Step-by-step explanation:

add both expressions together. 14y+6. Then set this equal to 90, because this is a 90 degree angle. Solve for y. 84=14y. y=6

Step-by-step explanation:

90= 6y+5+8y+1

14y=84

y=6

Answer:

60°

Step-by-step explanation:

Because of the rule that all triangle's angles must measure to 180°.

So I did...

60+60=120

180-120= 60

Answer

60 degrees

Step-by-step explanation:

A triangle is 180 degrees. So if you add both 60 degrees it would equal 120, substracted by 180 and you'll get 180. Or if you want to go the faster way, remember that a triangle will equal 180.

Answer:

7.5

Step-by-step explanation:

it's basically just 15 divided by 2

The equivalent value of the expression (1/2 x 15) is 7.5.

In mathematics, an algebraic expression is an expression built up from constant algebraic numbers, variables, and the algebraic operations.

Given is to solve the expression as -

1/2 x 15

We can write the expression as -

{x} = 1/2 x 15

{x} = 15/2

{x} = 7.5 x 2/2

{x} = 7.5

Therefore, the equivalent value of the expression (1/2 x 15) is 7.5.

Step-by-step explanation:

Answer:

the answer is 21.

Answer:

21.33 units (rounded)

Step-by-step explanation:

The height, x, can be determined through the Pythagorean Theorem:

a^2+b^2=c^2 (where b will be our height)

(22/2)^2+b^2=24^2

121+b^2=576

b^2=455

b=21.33072901

So the height is about 21.33 units
