If represents the number of bacteria in a culture at time t, how many will there be at time
Answer:
Population of bacteria at time [tex]t = 6[/tex] is [tex]2441[/tex]
Step-by-step explanation:
The complete question is
If [tex]y = 10 (2.5)^t[/tex]represents the number of bacteria in a culture at time t, how many will there be at time [tex]t = 6[/tex]
Solution
Given
The population of bacteria after time t is equal to [tex]y = 10 (2.5)^t[/tex]
Population when at time [tex]t = 6[/tex]
We will substitute the value of time in above equation.
[tex]y = 10 (2.5)^6\\y = 10 *244.14\\y = 2441.4 = 2441[/tex]

Apple, carrot, and celery juices are mixed in a ratio 3 : 1 : 2. The amount of appe juice is 33 millimeters.
a) How much more apple juice is used in the mixture than carrot juice?
b) What is the total amount of the mixture?
Answer:
A) 3 times more apple juice is used than carrot juice aka 22 more millimeters
B) 66 millimeters
Step-by-step explanation :
3 : 1 : 2 aka 33 : 11 : 22
You have the ratio, so you just have to divide 33/3 and you know you have to multiply that awnser times the other ratios.
So...
33/3 = 11
3 x 11 = 33
1 x 11 = 11
2 x 11 = 22
So the ratio is 33 : 11 : 22
Then, A is asking you how much more apple juice than carrot juice, so subtract ( amount of apple juice - amount of carrot juice )
33 - 11 = 22 millimeters more apple juice than carrot juice
Then, B is asking you how much juice is there in total. So just add all the juices together....
33+22+11 = 66
So 66 milimeters of juice all together
(a) The apple juice is 22 ml more than the carrot juice.
(b) The total amount of the mixture is 66 ml.
Ratio:Important information:
The ratio of Apple, carrot, and celery is 3 : 1 : 2.Amount of apple juice is 33 ml.(a)
Let the quantity of Apple, carrot, and celery is 3x, x, 2x respectively.
[tex]3x=33[/tex]
[tex]x=11[/tex]
Difference between Apple and carrot juice is:
[tex]3x-x=2x[/tex]
[tex]3x-x=2(11)[/tex]
[tex]3x-x=22[/tex]
Therefore, the apple juice is 22 ml more than the carrot juice.
(b)
The total amount of the mixture is:
[tex]3x+x+2x=6x[/tex]
[tex]3x+x+2x=6(11)[/tex]
[tex]3x+x+2x=66[/tex]
Therefore, the total amount of the mixture is 66 ml.

Answer:
f(x) = x^4 -x^3 +7x^2 -9x -18
Step-by-step explanation:
The imaginary root has a corresponding conjugate that is also a root. Each root has a corresponding factor: (x -p) for root p.
f(x) = (x -3i)(x +3i)(x -(-1))(x -2)
f(x) = (x^2 +9)(x^2 -x -2) . . . . combine pairs of factors
f(x) = x^4 -x^3 +7x^2 -9x -18 . . . . finish multiplying it out

Marty can go to one movie on either Friday or Saturday. His choice of movies includes a comedy or an action movie. Which list shows all of the possible outcomes of one movie on one day?
the list of all possible outcomes is: {Comedy on Friday, Action on Friday, Comedy on Saturday, Action on Saturday}
What is possibility?
Possibility refers to the likelihood or chance that something may occur or be true. It is often expressed as a probability or a percentage, which indicates the relative frequency with which an event is expected to happen.
In everyday language, possibility is often used to describe something that could happen or be true, but is not necessarily guaranteed. For example, if there is a 50% chance of rain tomorrow, it is possible that it will rain, but it is not certain.
In mathematics and statistics, possibility is often used in the context of probability theory, which is the branch of mathematics that deals with the study of random events and their probabilities.

[tex]\frac{x}{2}[/tex] -[tex]\frac{x}{5}[/tex]=2
Give your answer in its simplest form.
Step-by-step explanation:
[tex] \tt{ \frac{x}{2} - \frac{x}{5} = 2}[/tex]
Take the L.C.M of 2 & 5. It's ' 10 '. Firstly find out the factors of 2 [ i.e 1 × 2 ] and then secondly find out the factors of 5 [ i.e 1 × 5 ]. Now , Note that while finding L.C.M of any numbers, Common numbers & Remaining numbers must be multiplied. In our case , common number = 1 & Remaining numbers are 2 & 5. Multiply them : [ 1 × 2 × 5 = 10 ].
⟶ [tex] \tt{ \frac{x \times 5 - x \times 2}{10} = 2}[/tex]
⟶ [tex] \tt{ \frac{5x - 2x}{10} = 2}[/tex]
Subtract 2x from 5x :
⟶ [tex] \tt{ \frac{3x}{10} = 2}[/tex]
Apply cross product property :
⟶ [tex] \tt{3x \times 1 = 2 \times 10}[/tex]
⟶ [tex] \tt{3x = 20}[/tex]
Here, We have to think about how to remove the coefficient 3. For that , Divide both sides of the equation by 3.
⟶ [tex] \tt{ \frac{3x}{3} = \frac{20}{3}} [/tex]
⟶ [tex] \tt{x =6.67}[/tex]
[tex] \pink {\boxed{ \boxed{ \tt{⇾ Our \: final \: answer : \boxed{ \underline{ \tt{x = \frac{20}{3} \: or \: 6.67 }}}}}}}[/tex]

Answer:
x = 11

n = 4
Step-by-step explanation:
Three equations
Look for x
Look for y
Look for n
__________________
Note that all of these are questions can be answered through isolating the variable.
Let's start with x :
Get x alone :
2(x + 5) = 3x + 1
Distribute :
(2(x) + 2(5))
2x + 10 = 3x - 1
Add 1 to both sides of the equation :
2x + 11 = 3x
Subtract 2x from both sides :
11 = x
x = 11
Next is y :
Isolate y :
3y - 4 = 6 - 2y
Add 4 to both sides :
3y = 10 - 2y
Add 2y to both sides :
5y = 10
Divide 5 from both sides to get y by itself :
y = 2
Lastly is n :
Isolate n :
3(n + 2) = 9(6 - n)
Distribute :
(3(n) + 3(2)) = (9(6) - 9(n))
3n + 6 = 54 - 9n
Subtract 54 from both sides :
3n - 48 = -9n
Subtract 3n from both sides :
-48 = -12n
-12n = -48
Divide -12 from both sides :
n = 4
