Answer:
m=1/3
Step-by-step explanation:
so find slope do this
(y^2-y^1)/(x^2-x^1)
so
(1+2)/(-3-6)
1/3
Answer:
AB = 32
Step-by-step explanation:
Given:
AD = 40
CD = 9
Required:
Find the length of segment AB
Solution:
BC and CD are radius of the circle. Therefore,
BC = CD = 9
AB = AC - BC
AB = AC - 9
We need to find AC
Since AD is tangent, CD is perpendicular to AD, this means that <D is a right angle. This makes ∆ADC a right triangle.
Therefore, we can apply Pythagorean theorem to find AC.
Thus:
AC² = AD² + CD²
AC² = 40² + 9²
AC² = 1,681
AC = √1,681
AC = 41
Let's find BC:
AB = AC - 9
Plug in the value of AC
AB = 41 - 9
AB = 32
Check the forward differences of the sequence:
22 - 8 = 14
50 - 22 = 28 = 2*14
106 - 50 = 56 = 4*14
218 - 106 = 112 = 8*14
442 - 218 = 224 = 16*14
The differences are the products of increasing powers of 2 and 14:
and so on, with
Then the sequence has the recursive definition,
