Who invented math and how we know the right
Alla [95]

Answer:

Beginning in the 6th century BC with the Pythagoreans, with Greek mathematics the Ancient Greeks began a systematic study of mathematics as a subject in its own right. Around 300 BC, Euclid introduced the axiomatic method still used in mathematics today, consisting of definition, axiom, theorem, and proof.

Archimedes is known as the Father Of Mathematics. He lived between 287 BC – 212 BC. Syracuse, the Greek island of Sicily was his birthplace.

Necessarily we don't know if math is 'right', for there are solvable problems and unsolvable problems.

A=20,000(1.08)^t Is this equation exponential growth or decay? explain your answer
Talja [164]

Answer:

growth

Step-by-step explanation:

Exponential function represents f (x) = a ^ x

First, the derivative is f '(x) = xa ^ (x-1)

Because when a is greater than 1

(1.08>1)

The values of derivative functions are all greater than 0, so they are monotonically increasing in the domain of definition

So when the base number is greater than 1, it is an increasing function

And the larger the index, the larger the number

I hope it can help you
