Answer: 
Step-by-step explanation: Given expression
.
The first factor
has a degree of : 2 because power of a is 2.
The second factor
has a degree of : 3 because power of a is 3.
The third factor
has a degree of : 2 because highest power of a is 2.
Let us multiply them now:

First we would multiply
.
According to product rule of exponents, we would add the powers of a.
Therefore,

Now, we need to distribute
over 
Therefore,

=
Highest power of resulting polynomial
is 7.
Therefore, The product has a degree of 7.
First find the mean (sum divided by number of values)
4+5+8+10+15=42
42/5=8.4
Then find the difference between each of the numbers and the mean.
4.4, 3.4, 0.4, 1.6, 6.6
Then find the mean of those values.
4.4+3.4+0.4+1.6+6.6=16.4
16.4/5=3.28
Final answer: 3.28
Thicknesses at different point are: <span>41, 38, 36, 29, 34, 44, 46, 43, 35, 40
In increasing order: 29, 34, 35, 36, 38, 40, 41, 43, 44, 46
Median = (38+40)/2 = 39m</span>
Median thickness is 39m
Answer:
648 followers
Step-by-step explanation:
Let first day=a1
Tripled followers everyday
Second day=a2=a1×3
Third day=a3=a2*3
Fourth day=a4=a3*3
Fifth day=a5=a4*3
a=8 followers
a2=a1×3
=3*8
=24 followers
a3=a2*3
=24*3
=72 followers
a4=a3*3
=72*3
=216 followers
a5=a4*3
=216*3
=648 followers
On the fifth day, Alex will have a total of 648 followers on his new social media account.
