Domain is set of all x-values. You are supposed to focus on the x-axis instead.
From the graph, the point starts from x = -5 and ends on x = 5. That means no values would exist after x = 5 or before x = -5.
Hence, the domain starts from -5 to 5.
Answer
Answer:
x =(5/3)
Step-by-step explanation:
The given expression is 
Now to simplify it,
The first step is to cross multiply.
So, the expression becomes
or, -1 = 3x - 6
⇒ 3x = -1 + 6
⇒ 3x = 5 , or x =(5/3)
So add all the numbers together (20 + 22 + 28 + 35 + 47 + 90) and you'll get 242. Then you take the number and divide it by the numbers in your set (you have 6 numbers so you'll divide by 6) 242/6. The answer would be 40.3333333 (repeating decimal). I hope this helps!
Time is C. 50 seconds
Step-by-step explanation:
The population of bacteria at time t here is given by
where
b is the number of bacteria
t is the time in seconds
Here we want to find the approximate time at which the number of bacteria is
b = 625
Substituting into the equation and solving for t, we find:
Therefore, the solution is
C. 50 seconds

Answer:
Circle
Step-by-step explanation:
This object is what we call "circle". All the points in the circle are at the same distance from a given point which is the center of the circle. Moreover, the distance between the center and every point on the circle is called "radius". Higher values for the radius imply points at a higher distance from the center.
Additionally, we can calculate the perimeter of the circle, or the circumference, with the following formula:
circumference = 2*(radius) pi
Where pi is an irrational number usually used as 3.14.
If you have doubts, try to draw a circle and measure the distance between the center and any point on the circle.
