Answer:
∠95
Step-by-step explanation:
Hello There!
the measure of supplementary angles add up to equal 180
so to find an angle that is supplementary to angle 85 we subtract it from 180
180-85-95
so an angle that is supplementary to angle 85 would have a measure of 95 degrees
It's a. 3.
because
3+6x=21
6x=18
x=3.
Answer:
V = 486
, or approx. 1,526.814
Step-by-step explanation:
V =
*r²*(h/3)
plug in the numbers: V =
* (9)² * (18/3)
simplify: V =
* 81 * 6
simplify: V = 486
, or approx. 1,526.814
Answer:
Recursive formula is: 
Explicit formula is: 
Step-by-step explanation:
We need to find recursive formula and explicit formula for arithmetic sequence -1,6,13,20,27
In the given sequence First term a₁= -1
Common difference d = 7
Finding Recursive Formula
The recursive formula is of type:
and 
Since the First term a₁ is -1 and common difference d is 7 so, the recursive formula for given arithmetic sequence will be:

Finding Explicit Formula
The explicit formula is of type: 
We have
First term a₁= -1
Common difference d = 7
So, explicit formula will be:

So, explicit formula is:
