17 = 5k-2
+2 +2 The first step is to add 2 to both sides
-------------
19 = 5k Then you divide both sides by 5
The answer is 3.8 = k
When you foil it out you should get: 2x^5-2x^3-12x. When you factor it out completely you get: 2x(x^2-3)(x^2+2)
Answer:
202 cm^2
Step-by-step explanation:
SA = 2LW + 2LH + 2WH
SA = 2(4 cm)(5 cm) + 2(4 cm)(9 cm) + 2(5 cm)(9 cm)
SA = 40 cm^2 + 72 cm^2 + 90 cm^2
SA = 202 cm^2
Answer:
The answer is 11, I think, hope this helps!
Step-by-step explanation:
Given:
First term of an arithmetic sequence = 5
Second term = 3
To find:
The explicit formula for the given arithmetic sequence.
Solution:
We have,
First term: 
Second term: 
Common difference is



Now, the explicit formula for an arithmetic sequence is

where, a is first term and d is common difference.
Putting a=5 and d=-2, we get

It can also be written as


Here, n is an integer greater than or equal to 1.
Domain is the set of input values.
Therefore, the explicit equation is
or
and domain is all interest greater than or equal to 1.
