Number of hours worked: 8
earning per hour = $9
tax = 16%
First, multiply the number of hours by the earnings per hour:
8 x 9 = $72 (total earnings)
Now, find the tax amount by multiplying the total earnings by the tax percentage in decimal form (divided by 100)
72 x (16/100)= 72 x 0.16 = $11.52
Finally, subtract the tax amount to the total earnings:
Money left: 72-11.52 = $ 60.48
We call two numbers a and b, notice a>b
<span>The sum of two numbers is 110: a+b=110
</span><span>The larger number is 2 less than 7 times the smaller: a=7b-2
And by replacing a=7b-2 we have an equation: 7b-2+b=110
or 8b=110+2, and 8b=112, that means b=112:8= 14
We have two numbers: 14 and 96</span>
Answer:
Radius of the convergence is R = 
and,
The Interval of convergence is 
Step-by-step explanation:
Given function : Σ(21x)^k
Now,
Using the ratio test, we have
R = 
or
R = 
or
R = 
now,
for convergence R|x| < 1
Therefore,
< 1
or
and,
Radius of the convergence is R =
and,
The Interval of convergence is
The vertex is at (0,-5), therefore the range goes from (-infinity, - 5]
