Answer:

a. 21, ., ., 89

b. the sequence is 12, 13,25,38,63,101,164,265,429,

Step-by-step explanation:

The Fibonacci Sequence is regarded as a Rule whereby  xₙ = xₙ₋₁+ xₙ₋₂

where:

xₙ is the number of terms "n"

xₙ₋₁ is the previous term (n-1)

xₙ₋₂ is the term before that (n-2)

(n)        1st   2nd    3rd    4th     5th    6th     7th     8th       9th      10th         11th

           x₁     x₂        x₃      x₄       x₅       x₆      x₇        x₈          x₉         x₁₀          x₁₁

xₙ          1      1         2        3        5         8      13         21    (21+13)   21+(21+13)

                                                                                             34       21+34=55

for the sequence 1,1,2,3,5,8,13,...........

a.) the next term of the sequence is the 8th number

following the rule  = xₙ = xₙ₋₁+ xₙ₋₂

equate the n as the 8th term

x₈ = x₈₋₁+ x₈₋₂

x₈ = x₇+ x₆ = 13 + 8 = 21

the eleventh term of the sequence is  x₁₁

x₁₁ = x₁₁₋₁+ x₁₁₋₂

x₁₁ = x₁₀+ x₉ =  55+34 = 89

B. i will choose 12,13 as an open end set, the next 7 terms will be

first term = 12

second term = 13

third term = 12+13= 25

fourth term = 25+13=38

fifth term = 38+25 = 63

sixth term = 63+38 = 101

seventh term = 101+63 = 164

eight term = 164+101 = 265

ninth term = 265+164 = 429

the sequence is 12, 13,25,38,63,101,164,265,429,

The answer is 1 over 6, 1/6.
Since the denominators (bottom numbers) are the same then they don't need to be changed and can therefore be simplified by subtraction.

Find the equation of the line that is perpendicular to y = x+1<br> and contains the point (9,12).
emmasim [6.3K]

Answer:

y = -x + 21

Step-by-step explanation:

Equations that are perpendicular don't normally have the same slope as the original equation..

When you graph the given equation and the point, we can see that in order to make an equation that would cross through (9,12) and the line, we would need an equation with a negative slope.

**Using desmos (online graphing calculator)

If we continue to plug in numbers for our slope, we see that the equation

y = -x + 21  goes through point (9,12) and is perpendicular (intersecting or crossing through) line y = x + 1.

We can check our work by plugging in the coordinates of the point 9, 12 into our equations to see if they equal the same values..

y = -x + 21 --> 12 = -9 + 21 --> 12 = 21 - 9 --> 12 = 12 (correct)

Looks like all real numbers cause it doesn't stop anywhere, and it has coordinates at areaa greater than -2 less than 3 and less than -2 so the other choices are wrong, also range is Y D is not correct
