Middle option.

<span>(x + 1 ≤ 1) ∩ (x + 1 ≥ 1)

If you work both sides separately you get

</span>(x ≤ 0) ∩ (x ≥ 0)
<span>
which reduces nicely to

</span><span>{x | x = 0}</span>

Alex Ar [27]

Answer: C

Step-by-step explanation:

We know that $\angle AHB=90^{\circ}$ , and thus by the exterior angle theorem,

$90^{\circ}+\alpha=4\alpha\\\\90=3\alpha\\\\\alpha=30^{\circ}$

Thus, $\angle CAB=2\theta=\boxed{60^{\circ}}$

The formula for finding the number of bacteria present is given by P=P0(10)t where P is the final population, P0 is the initial

frozen [14]

Answer:

5.45 hours.

Step-by-step explanation:

The formula =

P = P0(10)t

In this circumstance, P0 = 275, P = 15,000 and t = ?

Applying the values into the formula:

P = P0(10)t

15,000 = 275 × (10) × t

15,000 = 2750t

t = 15,000/2750

t = 5.45 hours
