Replace ∗ with a monomial so that the trinomial may be represented by a square of a binomial: 25a^2+ ∗ + 1/4b^2
Nadya [2.5K]
The square of a binomial is a pattern you would do well to remember.
.. (x +y)^2 = x^2 +2xy +y^2

Your expression has x^2 = 25a^2, so x = 5a. It also has y^2 = (b^2)/4, so y = b/2.
then the middle term is
.. 2xy = 2(5a)(b/2) = 5ab

The trinomial is
.. 25a^2 +5ab +(1/4)b^2 = (5a +b/2)^2

How many solutions does the equation 3x + 6 equals -1 - 3 + 4x have?
jenyasd209 [6]
3x + 6= -1 - 3 + 4x
combine like terms

3x + 6= -4 + 4x
subtract 3x from both sides

6= -4 + x
add 4 to both sides

10= x


ANSWER: x= 10; This equation has one answer.

Hope this helps! :)

The number of bacteria in a certain population increases according to a continuous exponential growth model, with a growth rate
marissa [1.9K]

Step-by-step explanation:

Continuous exponential growth model:

population = population(t = 0) \times e ^{ \alpha t}

Where α is the growth rate parameter.

So if t is the starting point and t+t1 is the point that population is doubled:

\frac{population(t + t1)}{population(t)}  = \frac{2 \times population(t)}{population(t)}  = 2 =  {e}^{ \alpha \times t1 }

So:

ln(2)  =  \alpha  \times t1

And as a result, t1, the time needed for the population to double at ANY given point is equal to:

t1 =  \frac{ ln(2) }{ \alpha }
