Within the set of whole numbers , one set of numbers satisfies the recursive formula an=(an-1)^2-an-1, when a4=870 what are the
andrew11 [14]

Answer: 3 and 6 will be the first and second term of the given series respectively.

Explanation:  since it is given-  a_n=(a_{n-1} )^2-a_{n-1} and a_4=870

so, by replacing n by 4, we will get- a_4=a_3^2-a_3⇒870= a_3^2-a_3⇒ a_3^2-a_3-870=0

after solving this equation we will get, a_3= -29 and 30.

If a_3= -29, but it is not a whole number.

Thus,a_3=30 will be the value of third term of the given series.

Again, by applying the given condition a_n=(a_{n-1} )^2-a_{n-1}, a_2= 6 or -5 (not possible), so, a_2=6 will be the second term.

Similarly, a_1=3 or -2 but  we will go to the whole number.

Thus, a_1=3 will be the first term.

Find the y-intercept of a line parallel to 8x – 2y = 12 and passes through the point (5, 3).
Dmitry_Shevchenko [17]

Answer:

-17

Step-by-step explanation:

8x -2y= 12

<em>Divide</em><em> </em><em>the</em><em> </em><em>whole</em><em> </em><em>equation</em><em> </em><em>by</em><em> </em><em>2</em><em>:</em>

4x -y= 6

<em>Rewrite the equation into the slope-intercept form (y=mx+c, where m is the gradient while c is the y-intercept).</em>

-y= -4x +6

y= 4x -6

Thus, gradient of given line= 4.

Since parallel lines have the same gradient, gradient of line= 4.

y= 4x +c

<em>To find the y-intercept of the lone, substitute a pair of coordinates.</em>

When x=5, y=3,

3= 4(5) +c

3= 20 +c

c= 3 -20

c= -17

Thus, the y-intercept of the line is -17.
