Step-by-step explanation:
Answer:
No
Step-by-step explanation:
No, this is not an arithmetic sequence because it goes up by a different number each time.
An example of an arithmetic sequence would be,
3, 5, 7, 9...
because it increases by 2 each time.
A geometric sequence is multiplied or divided by a set number each time.
An example would be,
2, 4, 8, 16...
because it is multiplied by 2 each time.
Answer:
They have two digits after the decimal point − or we say they have two decimal digits. We can also illustrate hundredths by dividing a square into a hundred parts.
Step-by-step explanation:
Answer:
We should attempt synthetic division to find when
x
3
−
k
x
2
+
2
k
x
−
15
x
−
3
has a remainder of
0
, which would signify that it is a factor of the polynomial.
The synthetic substitution would be set up as:
3
−
∣
∣
∣
1
−
k
2
k

−−−

Treating the synthetic division like any other synthetic division problem, we see that

If the remainder equals

, then we know that

Solve this to see that
k

.
Thus,
(

)
is a factor of
