Answer:

Step-by-step explanation:

Recall that the quantity 25^(1/2) with fractional exponent 1/2 can be rewritten in the equivalent √25. In other words, the exponential form

25^(1/2) has the same value (outcome) as does √25.

In general, b^(1/a) is equivalent to (index a root of b).

Find the Mid point of (-5,-9) (-7,-4)

lyudmila [28]

Answer: ( -6 , -6.5 )

Step-by-step explanation:

The formula for calculating Mid - point is given by

M = ( $\frac{x_{1}+x_{2}}{2}$ , $\frac{y_{1}+y_{2}}{2}$ )

$x_{1}$ = -5

$x_{2}$ = -7

$y_{1}$ = -9

$y_{2}$ = -4

substituting into the formula , we have

M = $\frac{-5-7}{2}$ , $\frac{-9-4}{2}$

M = $\frac{-12}{2}$ , $\frac{-13}{2}$

Therefore : mid point = ( -6 , -6.5 )

Who invent natural numbers???

makkiz [27]

Answer:

nobody

Step-by-step explanation:

Humans have made use of natural numbers as long as humans have been around. Counting numbers are wired into our consciousness, as they are for many living things.

Research has demonstrated some plants can count up to 5 (generally, carnivorous ones). Honeybees have long been known to be able to count to 4, and recent research shows they can count higher. Fish can count; birds can count; as can many other species.

For most, it takes concentration and/or training to count beyond 4. We are born with an understanding of 1, 2, 3, more.

Nobody "invented" natural numbers.

_____

<em>Additional comment</em>

Prey species survive by being able to count predators. Some predators take advantage of the limitations of number recognition by hunting in groups larger than can be readily counted.
