Answer:
It forms a 90 degree angle
Step-by-step explanation:
Since a circle is 360 degrees, 1/4 of that would be 90.
Let us assume the initial number of bacteria in the culture = xAfter 1 hour,The number of bacteria = 185x/100 = 1.85xAfter 2 hours,The number of bacteria = (185 * 1.85x)/100 = 3.42xSo3.42x = 12500x = 12500/3.42 = 3654.97 = 3655From the above deduction, we can conclude that the initial number of bacteria in the culture is 3655.
Well the line is called a ray because because the left of the endpoint is a dot and it doesn't go anywhere. So your answer is a ray.

Using a calculator, you should find that
-2 & 4/5 = -(2 + 4/5) = -(2+0.8) = -2.8
-31/5 = -6.2
So the unknown number is between -6.2 and -2.8
<h3>Possible whole number answers could be: -6, -5, -4, -3, or -2</h3>
If your teacher allows decimal answers, then there are infinitely many possible ways to answer.
You may recall that you can't take the square root of a negative number (if you want a real number). So, the area under the square root, also known as the radicand, must be zero or positive. This is how we restrict the domain.
We write the inequality
