Answer:

History of mathematics

Several civilizations — in China, India, Egypt, Central America and Mesopotamia — contributed to mathematics as we know it today. The Sumerians were the first people to develop a counting system. Mathematicians developed arithmetic, which includes basic operations, multiplication, fractions and square roots. The Sumerians’ system passed through the Akkadian Empire to the Babylonians around 300 B.C. Six hundred years later, in America, the Mayans developed elaborate calendar systems and were skilled astronomers. About this time, the concept of zero was developed.

Step-by-step explanation:

<u>Compound Interest</u>

It's the type of financial calculations that includes the interest of previous periods into the new interests earned by some initial investment or principal P.

If we want to compute the final value FV of a series of n payments R at a fixed compound interest rate i, then

$FV=F_m\cdot R$

Where

$\displaystyle F_m=\frac{(1+i)^n-1}{i}$

The question provides us the following data

i=10% compounded twice a year

n=3 1/2 years

FV=15,000

We need to convert the number of periods and the interest rate to a semester base:

$\displaystyle i=\frac{10}{100\cdot 2}=0.05$

$n=3.5\cdot 2= 7\ semesters$

Let's calculate Fm

$\displaystyle F_m=\frac{(1+0.05)^7-1}{0.05}=8.142$

Knowing that

$FV=F_m\cdot R$

Solving for R

$\displaystyle R=\frac{FV}{F_m}=\frac{15,000}{8.142}=1,842.30$

Sara should deposit $1,842.30 twice a year to have the down payment for her own restaurant

The equal symbol with the wave meat "is Congeruent to"

Strike441 [17]

Answer:

angle 5 is 61°

angle 7 is 61°

Step-by-step explanation:

1. angle 7 + angle 8 = 90° Because they are complementary angles

2. Because of point 1 above, angle 5 + angle 6 = 90°

3. since given angle 6 = 29°

so, angle 5 = 90° - 29° = 61°

4. since given angle 5 = angle 8

so, angle 8 = 61°

5. from point 1 above,

angle 7 + 61° = 90°

so angle 7 = 29°
