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]

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

Answer:

The value of k is:

[tex]k=-\frac{31}{4}[/tex]

Step-by-step explanation:

Given

The line containing the points (-3,k) and (4,8) is parallel to the line containing the points (5,3) and (1,-6).

To determine

what is the value of k?

To determine the value of k, the first step we need to do is to find the slope of the line containing the points (5,3) and (1,-6) using the formula

[tex]\mathrm{Slope}=m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Here:

now substituting (x₁, y₁) = (5, 3)  and (x₂, y₂) = (1, -6) in the formula

[tex]m=\frac{-6-3}{1-5}[/tex]

[tex]m=\frac{-9}{-4}[/tex]

Apply the fraction rule:  [tex]\frac{-a}{-b}=\frac{a}{b}[/tex]

[tex]m=\frac{9}{4}[/tex]

Thus, we conclude that the slope of the line containing the points (5,3) and (1,-6) will be:

[tex]m=\frac{9}{4}[/tex]

Importing Tip:

Thus, using the slope formula for the line containing the points (-3,k) and (4,8).

[tex]\mathrm{Slope}=m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Here:

As we know that the parallel lines have the same slopes.

Thus, the second step we need to do is to substitute m = 9/4 in the slope formula

[tex]\frac{9}{4}=\frac{y_2-y_1}{x_2-x_1}[/tex]

now substituting (x₁, y₁) = (-3, k)  and (x₂, y₂) = (4, 8) in the formula

[tex]\:\:\:\frac{9}{4}=\:\frac{8-k}{4-\left(-3\right)}[/tex]

switch sides

[tex]\frac{8-k}{4-\left(-3\right)}=\frac{9}{4}[/tex]

Multiply both sides by 7

[tex]\frac{7\left(8-k\right)}{4-\left(-3\right)}=\frac{9\cdot \:7}{4}[/tex]

Simplify

[tex]8-k=\frac{63}{4}[/tex]

Subtract 8 from both sides

[tex]8-k-8=\frac{63}{4}-8[/tex]

Simplify

[tex]-k=\frac{31}{4}[/tex]

Divide both sides by -1

[tex]\frac{-k}{-1}=\frac{\frac{31}{4}}{-1}[/tex]

Simplify

[tex]k=-\frac{31}{4}[/tex]

Therefore, the value of k is:

[tex]k=-\frac{31}{4}[/tex]

VERIFICATION:

As the value of k = -31/4.

So the first line will contain the points:

Finding the slope between (-3, -31/4) and (4, 8) using the slope formula

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

Here:

so substituting (x₁, y₁) = (-3, -31/4)  and (x₂, y₂) = (4, 8) in the formula

[tex]m=\frac{8-\left(-\frac{31}{4}\right)}{4-\left(-3\right)}[/tex]

Apply rule:  [tex]-\left(-a\right)=a[/tex]

[tex]m=\frac{8+\frac{31}{4}}{4+3}[/tex]

Add the numbers:  [tex]4+3=7[/tex]

[tex]m=\frac{8+\frac{31}{4}}{7}[/tex]

[tex]m=\frac{\frac{63}{4}}{7}[/tex]           ∵ [tex]8+\frac{31}{4}=\frac{63}{4}[/tex]

Apply fraction rule:  [tex]\frac{\frac{b}{c}}{a}=\frac{b}{c\:\cdot \:a}[/tex]

[tex]m=\frac{63}{4\cdot \:7}[/tex]

[tex]m=\frac{63}{28}[/tex]

Cancel the common factor:  7

[tex]m=\frac{9}{4}[/tex]

So, the slope of the line containing the points (-3,k) and (4,8) is m = 9/4. It means both lines have the same slopes. Hence, they are parallel.  

Therefore, we conclude that the value of k = -31/4 is true.

Answer:

$12.35

Step-by-step explanation:

to figure out how much justine spends we need to multiply 1  1/3 with 5.30

1  1/3=4/3

4/3=1.33(decimal for easy calculations)

1.33*5.30=7.05

so now to figure out how much BOTH the girls spend:

7.05+5.30=12.35

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.

Important information:

(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.
