<span>cos (X) + sin (X) = 0

Subtract cos(x) from each side:

sin(x) = -cos(x)

Divide each side by cos(x) :

sin(x) / cos(x) = -1

But sin/cos = tangent

<em>tan(x) = -1</em>

x = 135° and 315°

x = 3/4 pi radians  and  7/4 pi radians

Answer:

Step-by-step explanation:

Remark

My guess is that what is confusing you is not what you have to do, but why it is disguised as g(n)

What you are doing in effect is setting up a table. You are also not certain where the table starts. And that is a problem. I will start it at zero, but it might be 1.

zero

n = 0

g(0) = 34 - 5*0

g(0) = 34

One

n = 1

g(1) = 34 - 5*1

g(1) = 34 - 5

g(1) = 29

Two

g(2) = 34 - 5*2

g(2) = 34 - 10

g(2) = 24

Three

g(3) = 34 - 5*3

g(3) = 34 - 15

g(3) = 19

Four

g(4) = 34 - 5*4

g(4) = 34 - 20

g(4) = 19

Answer

0      1       2       3      4

34  29     24     19     14

abruzzese [7]
For this case we have a function of the form:
 y = A * (b) ^ t
 Where,
 A: initial amount
 b: decrease rate
 t: time
 Substituting values we have:
 y = 200 * (0.946) ^ t
 Answer:
 
An exponential function showing the relationship between and and is:
 
y = 200 * (0.946) ^ t

Alex17521 [72]

Answer:

a) 952

b) 136

Step-by-step explanation:

<u>Ratio of b:g = 3:4, based on this we have:</u>

  • Number of boys = 3x
  • Number of girls = 4x
  • Total number of pupils = 3x+4x = 7x

<u>Number of spectacle wearers:</u>

  • 1/3*3x + 3/8*4x = x + 3/2x = 2.5x

<u>Number of those not wearing spectacles:</u>

  • 7x - 2.5x= 4.5x

<u>And this number equals to 612, then we can find the value of x:</u>

  • 4.5 x = 612
  • x= 612/4.5
  • x= 136

a) T<u>otal number of pupils:</u>

  • 7x = 7*136 = 952

b)<u> The difference in the number of boys and girls:</u>

  • 4x-3x= x = 136
