A(1)=20​​ <br> a(n)=a(n−1)−17​​ <br> Find the 3rd term in the sequence
Alexxx [7]
Answer: The third term is -14

----------------------------------------------

Explanation:

First term = A(1) = 20, which is given

Second term
A(n) = A(n-1) - 17
A(2) = A(2-1) - 17
A(2) = A(1) - 17 .... note: second term = (first term) - 17
A(2) = 20 - 17
A(2) = 3

Third term
A(n) = A(n-1) - 17
A(3) = A(3-1) - 17
A(3) = A(2) - 17 ... note: third term = (second term) - 17
A(3) = 3 - 17
A(3) = -14

Alex

Answer:

0.000462

Step-by-step explanation:

From the given information:

The cotton count of the piled yarn is the ratio of the simple weight in (g) with the length by the simple length with weight.

Mathematically:

Cotton count = \dfrac{simple \ weight \ in (g) \times \ length }{simple \ length \times unit \ weight }

Cotton count = \dfrac{1 \times 0.001 }{0.108 \times 20}

\mathbf{ Cotton \  count = 0.000462}

Y = 2x^2 + 3<br> im looking for how to find the axis of symmetry
andre [41]

The axis of symmetry of the quadratic equation y = 2x^2 + 3 is x = 0

<h3>How to determine the axis of symmetry?</h3>

The equation is given as:

y = 2x^2 + 3

Differentiate the above equation with respect to x

y' = 4x + 0

This gives

y' = 4x

Set the equation to 0

4x = 0

Divide both sides by 4

x = 0

Hence, the axis of symmetry is x = 0
