Answer:

The Recursive Formula of sequence is: 8, 5, 2, -1, -4,...

Step-by-step explanation:

Arithmetic Sequence is a sequence in which every two neighbor digits have equal distances.

For finding the nth term, we use formula

aₙ = a + (n - 1) d

where, aₙ = value of nth term

a = First term

n = number of term

d = difference

We have given that,

a₁₇ = -40  ⇒ a₁₇ = a + (17 - 1)d

⇒ -40 = a + 16d        →      (1)

Also, a₂₈ = -73  ⇒ a₂₈ = a + (28 - 1)d

⇒ -73 = a + 27d           →    (2)

Solving, equation (1) and (2), We get  

a = 8, d = -3

Hence, First term = a = 8

Second term = a + d = 8 - 3 = 5

Third term = 5 + d = 2

Fourth term = 2 + d = -1

Thus, The Arithmetic Sequence is: 8, 5, 2, -1, -4,...

What is the slope of a line that is perpendicular to the line y = 1?
ValentinkaMS [17]
Y = 1
Using y = mx + c.
Compare to y = 1,    y = 0x + 1 ,
We can see that the slope m = 0 and the vertical intercept, c = 1.
For the line perpendicular to  y = 1
Condition for perpendicularity  m₁m₂ = -1
m₁ = 0,  m₂ = ?
0*m₂ = -1
m₂ = -1/0 = Negative Infinite or Infinite 
Slope of line perpendicular to y = 1, is  = Infinite.

So the students are on 5:6 ratio from volleyball to football, and we know there are 220 students in total.

\bf \cfrac{volleyball}{football}\qquad 5:6\qquad \cfrac{5}{6}\implies \cfrac{5\cdot \frac{220}{5+6}}{6\cdot \frac{220}{5+6}}\implies \cfrac{5\cdot 20}{6\cdot 20}\implies \cfrac{100}{\stackrel{football}{120}}
