Hello there,

Well first we would need to find the slope of the two points...

  • In order to find the slope we would use y2-y1 divided by x2-x1 we plug it in \frac{-3--2}{0--3} or \frac{-3 + 2}{0 + 3}
  • we would get \frac{-1}{3} as the slope of the equation

The y-intercept of the equation would be when x is equal to 0 and the y-value would be. In this case one of the points is (0,-3) where -3 is the y-intercept.

Your new equation would be y = \frac {-1}{3} - 3

Hope I helped,

Amna

Sin 1 + sin 2 + sin3 .................+ sin 360 = ?
lesya [120]

Assuming that arcs are given in degrees, call S the following sum:

S = sin 1° + sin 2° + sin 3° + ... + sin 359° + sin 360°


Rearranging the terms, you can rewrite S as

S = [sin 1° + sin 359°] + [sin 2° + sin 358°] + ... + [sin 179° + sin 181°] + sin 180° +
   + sin 360°

S = [sin 1° + sin(360° – 1°)] + [sin 2° + sin(360° – 2°)] + ...+ [sin 179° + sin(360° – 179)°]
   + sin 180° + sin 360°          (i)


But for any real k,

sin(360° – k) = – sin k


then,

S = [sin 1° – sin 1°] + [sin 2° – sin 2°] + ... + [sin 179° – sin 179°] + sin 180° + sin 360°

S = 0 + 0 + ... + 0 + 0 + 0        (... as sin 180° = sin 360° = 0)

S = 0


Each pair of terms in brackets cancel out themselves, so the sum equals zero.

∴   sin 1° + sin 2° + sin 3° + ... + sin 359° + sin 360° = 0          ✔


I hope this helps. =)

A theater wants 2000$ and children's tickets cost 5$ and adult tickets cost 10$.What is one combination of children and adult ti
scZoUnD [109]

Answer:

Therefore the one  combination is

200 tickets of Children and 100 tickets of Adult.

Therefore Total Amount will be given as

5x+10y=2000     ..........As Required

Step-by-step explanation:

Given:

Children's tickets cost = 5$ (per ticket)

Adult tickets cost = 10$ (per ticket)

Total Amount = 2000$

Let the number of Children's Ticket be " x "

and the number of Adult's Ticket be " y "

Therefore,

Total cost for Children's Ticket will be = 5\times x

Total cost for Adult's Ticket will be = 10\times y

Therefore Total Amount will be given as

5x+10y=2000      ...........As Required

So there are many combinations to get 2000$ one of the as follow

Children's tickets cost = 1000$

∴ 5x = 1000\\x=\dfrac{1000}{5}=200\ tickets

Adult's tickets cost = 1000$

10x = 1000\\x=\dfrac{1000}{10}=100\ tickets

Therefore the one  combination is

200 tickets of Children and 100 tickets of Adult.
