Geometric sequences are mostly found in Book IX of Elements by Euclid in 300 B.C. Euclid of Alexandria, a Greek mathematician also considered the "Father of Geometry" was the main contributor of this theory. Geometric sequences and series are one of the easiest examples of infinite series with finite sums. Geometric sequences and series have played an important role in the early development of calculus, and have continued to be a main case of study in convergence of series. Geometric sequences and series are used a lot in mathematics, and they are very important in physics, engineering, biology, economics, computer science, queuing theory, and finance.<span> It was included in Euclid's book </span>Elements<span> that was part of a composition of other math theories for people that became very popular because it was the first collection that showed alot of the main math theories together featured simply.</span>

Which input in this table is incorrect?Cost ofTax onItem Item1.00.082.00 .163.00 .246.00 .5610.00.80Noter all entries are in dol

Norma-Jean [14]

From the table, we can observe that the formula for the total cost of item is

$\text{Total cost of item = Cost of item + Tax on item}$

From the data in the table, cost of item 6.00 has the input incorrect because the sum of the cost of its item and tax on the item is,

$\text{Total cost of item=6.00+56=6.56}$

but the total cost was incorrectly inputed as 7.56.

Hence, the correct option is Option A.

Hi need help on hw plz help me out my questions is - a rectangle has a length of 14cm and width 9.5cm the length increased by 6%

sweet-ann [11.9K]

Answer:

Part a) $21.9\%$

Part b) $82.03\%$

Step-by-step explanation:

we know that

The original area of rectangle is equal to

$A=(14)(9.5)\ cm^{2}$

so

if the length is increased by 6% and the width is by 15%

then

the new area is equal to

$A=[1.06(14)][1.15(9.5)]\ cm^{2}$

$A=(1.06*1.15)(14)(9.5)\ cm^{2}$

$A=(1.219)(14)(9.5)\ cm^{2}$

The new area is (1.219) times the original area

Part a) Calculate the percentage change in area of the rectangle

$1.219-1=0.219$

convert to percentage

$0.219*100=21.9\%$

Part b) what is the original area as a percentage of the increased area of the rectangle?

Divide the original area by the increased area

$\frac{(14)(9.5)}{(1.219)(14)(9.5)} =\frac{1}{1.219} \\ \\=0.8203$

Convert to percentage

$0.8203*100=82.03\%$

Which expression is equivalent to -35 3/5

Alex787 [66]

You can look at -32 as being -2^5 so if you write (-2^5)^3/5 the 5's cancel out making it -2^3 which equals -8
