Think, if something waves up and down at a certain rate, then its slope also will be changing with it along this wave at the same rate. If a function is periodic, with period c, then so is its derivative. I hope that this is the answer that you were looking for and it has helped you.
<span>I am detailing it to show you how to calculate an explicite equation
Arithmetic Progression First term 7 , second 3 hence d=3-7 = - 4</span>
n=Term rank ==>║ 1 2 3 4 5 6 7......n
Value ====>║ 7 3 -1 -5 -9 -13 -17.......
a(n) (sub Notation║ a₁ a₂ a₃ a₄ a₅ a₆ a₇.....a(n)
Term 1 = a₁ = 7........................7-4(0)
Term 2 = a₂ = 3........................7-4(1)
Term 3 = a₃ = -1.......................7-4(2)
Term 4 = a₄ = -5.......................7-4(3)
Term 5 = a₅ = -9.......................7-4(4)
Term n = a(n) ============7-4(n-1)
So A. an = 7 − 4(n − 1); all integers where n ≥ 1
Answer:
d = 5.10
Step-by-step explanation:
The distance between two points is given by
d = sqrt( ( y2-y1)^2 + ( x2-x1)^2 ) where ( x1,y1) and ( x2,y2) are the two points
d = sqrt( ( 5-6)^2 + (8-3)^2 )
d = sqrt( ( -1)^2 + (5)^2 )
d = sqrt( 1+25)
d = sqrt(26)
d = 5.099019514
Rounding to the nearest hundredth
d = 5.10
According to the problem's info, we have:
(1 + 2 + 4)pieces of fabric = 1bug
(7)pieces of fabric<span> = 1bug
</span>so we know for each bug Missy uses 7 pieces of fabric (of different shapes).
Then, if she uses 70 pieces (7*10) of fabric, those are 10 bugs(1*10) built.
so we have to multiply by 10 the amount of pieces used in one bug:
hexagonal = 1*10 = 10
rectangular = 2*10 = 20
triangular = 4*10 = 40
which give us 70 pieces total.
<u>Your question: </u>given that sin(30)=1/2 and cos(30)=(sqrt3)/2, use trigonometric identities to find the value of cot(30)
The correct answer would be D
