Answer:
9.6*10^-12
Step-by-step explanation:
To calculate this, you will do the mass of 2 times 10^(-12) gram. So, 2*(10)^-12. Then we know 30 hours = 480,000,000 bacteria.
So now now you calculate the mass, 480,000,000 * 2(10)^-12 which gives you 9.6*10^-4.
Sorry if it sounds confusing! I hope this helps, have a good day! :D

Given f(x)=x²-3x - 23 and
g(x)=x-1, find (fog)(x).
Answers
The required function is (fog)(x) = x^2 – 5x – 19
We have been given two functions which are:
f(x) = x^2 – 3x – 23
g(x) = x – 1
We need to find (fog)(x) which is also equal to f(g(x)).
In this, we have to replace x with the function g(x) in the function, f(x). numerically
f(g(x)) = g(x)^2 – 3g(x) – 23
Now we will write the value of g(x) in the above equation. We will get
f(g(x)) = (x-1)^2 – 3(x-1) – 23
f(g(x)) = x^2 + 1 – 2x – 3x + 3 – 23
f(g(x)) = x^2 – 5x – 19
Hence (fog)(x) = x^2 – 5x – 19 is the required function.

The value of x from the given line segment is 1 2/3.
Given that, line segment AC = 5 and line segment AB = 3x - 5.
We need to find the value of x.
What is the line segment?A line segment is a part of a line that has two endpoints and a fixed length. It is different from a line that does not have a beginning or an end and which can be extended in both directions.
Since point B is the midpoint of the line segment AC.
AB=BC=3x - 5
Now, AC=AB+BC
⇒5=3x - 5+3x - 5
⇒6x=15
⇒x=15/6
⇒x= 5/3
⇒x=1 2/3
Therefore, the value of x from the given line segment is 1 2/3.

Find ABD CBD and ABC
Answers
The measure of <ABD, <DBC and <ABC are 67, 67 and 134 degrees respectively.
Bisection of anglesAngles are bisected if they are divided into two equal parts.
If the angle BC bisects <ABC, hence <ABD and <DBC are equal, hence;
2(11x + 23) = <ABC
Given the following parameters
<ABC = 25x + 34
2(11x + 23) = 25x + 34
Expand
22x +46 = 25x + 34
22x-25x = 34 - 46
-3x = -12
x = 4
Determine the measure of the angles
<ABD = 11x + 23 = <DBC
<ABD = 11(4) + 23
<ABD = 44 + 23
<ABD = 67 degrees
<ABC = 2(67)
<ABC = 134 degrees
Hence the measure of <ABD, <DBC and <ABC are 67, 67 and 134 degrees respectively.

Simple interest:
Simple interest means the method of calculating the interest amount for a particular principal amount of money at some rate of interest.
The formula used to calculate the simple interest is
SI = P × R × T
P = The principal is the amount that initially borrowed from the bank or invested.
R = Rate is the rate of interest at which the principal amount is given to someone for a certain time.
T= Time is the duration for which the principal amount is given to someone.
Given,

The second lawn that Makayla mows has a length of 70 feet.
If the first lawn Makayla mows is 10 feet long and 7 feet wide, use the formula for the area of rectangle to know the area of the first lawn.

Area of first lawn = 10 feet x 7 feet
Area of first lawn = 70 ft^2
If the area of the second lawn is 7 times as big as the first, then the area of the second lawn is:
Area of second lawn = 7 x Area of first lawn
Area of second lawn = 7 x 70 ft^2
Area of second lawn = 490 ft^2
If the second lawn has the same width as the first, which is 7 feet, using the formula for the area of a rectangle, solve for the length of the second lawn.

You roll a number cube. What is the probability that you roll an even number or a number less than 5?
Answers
Next, the probability of rolling a number less then five is 4/6 (or 2/3 simplified), since we have 4 sides labeled with a number less than 5.
To compute two or more probabilities, we multiply them. In this case, the fractions already share the same denominator, 6 (because it’s a cube with 6 sides). So we get:
3/6 * 4/6
We then square 6, which is 36, and multiply 3 by 4, which is 12. This gives us 12/36, which is 1/3 in simplified form.
So there’s out answer: 1/3.

How are time, distance, and speed related?Speed indicates how quickly something or someone is moving. Speed is calculated as follows: speed = distance * time. Following are the relationships between time, distance, and speed: Distance is directly related to speed and time. Time and speed are also negatively related. Speed is what it means. the speed at which an object's location changes in any direction. The distance traveled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity. Distance is the sum of an object's movements, regardless of direction. The flow of events from the past into the future is known as time. Time only ever moves in one way. Time can go either forward or backward, but not both.

For a quadratic equation:

If D = 0 we have one real solution (it is thought as two equal solutions)
if D < 0, we have two complex solutions.
In this case, the quadratic equation is:
