Answer:
false
Step-by-step explanation:
Formula: c=2r
Circumference= two times pi times radius
I think it’s B). y ≤ x2 − 5
hope this helps!
Step-by-step explanation:
We have the closed circle on -6 and the ray drawn to the right (to the infinity).
Describe this set of real numbers in words:
All numbers not less than -6.
Describe this set of real numbers in set notation.
x ∈ [-6, ∞)
Write an equation or an inequality that has the set above as its solution set.
x ≥ -6
Answer:
First term (a) =8
Common difference (d)= t2-t1
=12-8
=4
Now, sum of first 31th term (tn31) =n/2{2a+(n-1)d}
= 31/2{2×8+(31-1)4}
=31/2{16+(30×4)
=31/2(16+120)
=31/2×126
=31×63
Step-by-step explanation:
Similarly use 19 as (n) for the 19th term
