Step-by-step explanation:
construct the perpendicular bisector of segment xy
Answer:
the answer is C. they are both positive.
Step-by-step explanation:
This is because over the y axis is the first quadrant which is always positive.
Answer:
Step-by-step explanation:
Given
Required
The nth term
The given sequence is a geometric sequence.
So, first we identify the first term
Calculate common ration
or 
So, the nth term is:
Answer:
7/12
Step-by-step explanation:
The nth term Tₙ = n(n-4) /n+3.
The 1st term T₁ = 1(1 - 4)/(1 + 3) = -3/4
The 6th term T₆ = 6(6 - 4)/(6 + 3) = 6(2)/9 = 2(2)/3 = 4/3
So, the sum of the 1st and 6th terms is T₁ + T₆ = -3/4 + 4/3
= (-9 + 16)/12
= 7/12
Answer:
<h3>
The second: f(-5) = 2</h3>
Step-by-step explanation:
x = -5
-5 < -4 and if x<-4 then f(x) = - 2x - 8
so:
f(-5) = - 2(-5) - 8 = 10 - 8 = 2
