Answer:

$12.5 x^{10}$ number of bacteria

Step-by-step explanation:

given as :

The Number of Bacteria in 2 L of water = $5 x^{10}$

∵ 2 L of water have = $5 x^{10}$ number of bacteria

So 1 L of water have = $\frac{5 x^{10}}{2}$ number of bacteria

∴ 5 L of water have = $\frac{5 x^{10}}{2}$ × 5 number of bacteria

= $12.5 x^{10}$ number of bacteria

Hence in 5 L of water , $12.5 x^{10}$ number of bacteria available Answer

Answer:

see explanation

Step-by-step explanation:

Given the recursive formula

$a_{n}$ = $\frac{1}{2}$ $a_{n-1}$ with a₁ = 1, then

a₂ = $\frac{1}{2}$ a₁ = $\frac{1}{2}$ × 1 = $\frac{1}{2}$

a₃ = $\frac{1}{2}$ a₂ = $\frac{1}{2}$ × $\frac{1}{2}$ = $\frac{1}{4}$

Which expression is equivalent to sine startfraction 7 pi over 6 endfraction?

never [62]

The equivalent expression to the given one is -sin(pi/6).

<h3></h3><h3>Which expression is equivalent to the given one?</h3>

The given expression is:

sin(7pi/6)

Where the argument is in radians.

Remember that:

sin(a + b) = sin(a)*cos(b) + sin(b)*cos(a)

Now we can rewrite:

sin(7pi/6) = sin(pi + pi/6)

Then we can use the above relation to rewrite:

sin(pi + pi/6) = sin(pi)*cos( pi/6) + sin(pi/6)*cos(pi)

And we know that:

sin(pi) = 0

cos(pi) = -1

Then we can write:

sin(7pi/6) = - sin(pi/6)
