Luke earned $36,000 during the first year of his job at Putt-Putt Kingdom. After each year he received a 10% raise. Find his tot
Lady_Fox [76]
In order to solve this problem, you need to use a geometric series:
S_{n} =  \frac{ a_{1}(1 - r^{n}) }{1 - r}
where:
a₁ = first term of the series = 36000
r = common rate = 10% raise, therefore 1.10
n = number of terms = 5

Therefore,
 <span>S_{n} =  \frac{ 36000(1 - 1.10^{5}) }{1 - 1.10}
= 219783.60 $

Luke's total earnings in five years are <span>219783.60 $.</span>

Help!!!!!!!!!!!!!!! A square tabletop has side lengths of (4x − 8) units. Enter a polynomial that represents the area of the tab
kherson [118]

Answer: 16x^{2}-64x+64

Step-by-step explanation:

1. The formula for calculate th area of a square is shown below:

A=s^{2}

Where s is the side of the square.

2. Therefore, if the square tabletop has side lengths of (4x-8) units you have:

(4x-8)^{2}

3. By definition, the square of a binomial is always a trinomial:

(a-b)^{2}=a^{2}-2ab+b^{2}

4. Then, you obtain:

(4x-8)^{2}=(4x)^{2}-2(4x)(-8)+8^{2}=16x^{2}-64x+64
