Answer:

8-x meters

Step-by-step explanation:

Both 64 and x^2 are perfect squares, since 64=(8)^2 and x^2=(x)^2.

Additionally, 16x is twice the product of the roots of 64 and x^2, since 16x=2(8)(x).

So we can use h the square of a difference pattern to factor:

a^2-2(a)(b)+b^2=(a-b)^2

In this case, a=8 and b=x:

(8)^2-2(8)(x)+(x)^2=(8-x)^2

In conclusion...

64-16x+x^2=(8-x)^2

So the side length of the square is 8-x meters.

A population of a particular yeast cell develops with a constant relative growth rate of 0.4225 per hour. The initial population
Ksju [112]

Answer: The population after 3 hours is 13.9 mill.

Step-by-step explanation:

When we have an exponential with:

A  = initial population.

r = constant relative growth rate:

t = time.

The function that models this is:

P(t) = A*e^(k*t)

In this case we know that:

A = 3.9 mill.

r = 0.4225 1.

Then the function that models the population of this yeast cell is:

P(t) = (3.9 mill)*e^(0.4225*t)

where t represents the time in hours.

Then if we want to know the population after 3 hours, we should replace t by 3.

P(3) = (3.9 mill)*e^(0.4225*3) = 13.85 mill.

And we want to round our answer to one decimal place, then we must look at the second decimal place, we can see that is a 5, so we should round up.

The population after 3 hours is 13.9 mill.

Is the square root of eight a rational or irrational number
shutvik [7]
\bf \sqrt{8}\implies \sqrt{2\cdot 2\cdot 2}\implies \sqrt{2^2\cdot 2}\implies 2\sqrt{2}

it just so happen that √2 is an irrational number, so any product with it as a factor, will yield an irrational number as well.



factoid:   Ancient Greeks were scared of irrational numbers, and they steered clear from √2.
