Answer:
B
Step-by-step explanation:
So for some reason the person didn't put the equations... I had the same question so here they are.
A.x^2 – 8x = 24
x2 – 8x + 4 = 24 + 4
B.x^2 – 8x = 24
x2 – 8x + 16 = 24 + 16
C.x^2 – 8x = 24
x2 – 8x + 64 = 24 + 64
D.x^2 – 8x = 24
x2 – 8x + 144 = 24 + 144
Good luck!
The quadratic equation can be solved by completing square method. The steps to solve the given equation are explained in detail.
What is a quadratic equation?The general form of a quadratic equation is given as ax^2 + bx + c = 0.
Here, a ≠ 0 and b and c are integers.
The degree of a quadratic equation is 2.
The given equation is,
x^2 - 8x -24 = 0
To solve this equation by completing square method, it has to be transformed into the form of (a + b)^2.
The steps for this method are given as follows,
(i) Find the coefficient of x^2. The square root of the this coefficient is the value of a.
(ii) Find the term containing non-square part. In the given case it is -8x.
(iii) Compare the coefficient of this term with 2ab. it gives,
2ab = -8
=> 2 × 1 × b = -8
=> b = -4
(iv) Write the equation in the form of a^2 + 2ab + b^2 leaving the remaining term as it is. For the given equation it can be written as,
x^2 - 8x + 4^2 - 40 = 0
=> x^2 - 8x + 4^2 = 40
(v) Now, write the equation in terms of (a +b)^2 and get the solution. In this case it is written as,
(x - 4)^2 = 40
=> x - 4 = ±√40
=> x = 4 ±√40

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

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.

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.
