A bacteria culture initially contains 2500 bacteria and doubles every half hour.

Find the size of the bacterial population after 20 minutes.
Find the size of the bacterial population after 8 hours.

Answers

Answer 1
First thing we have to do is find the growth rate k….the exponential model for this situation is B(t)=B0 ekt We are given that B0=2500 and the population doubles every 30 min (half hour)
so we know that at t=30 min that B(30) = 2*2500. Putting all this in the model equation gives

(2*2500/2500)=e30k solving for k gives k=Ln(2)/30=.02310 min-1 now we can calculate the size of the population at 20 min from

B(20)=2500e.02310*20 =1.587*2500=3968.

Compute the depreciation expense under straight-line method for 2022.
Depreciation expense $
2022

Answers

The depreciation expense under the straight-line method for 2022, for Monty Corp., is $5,450.

What is the straight-line depreciation method?

Under the straight-line depreciation method, one of the cost-recovery methods, the depreciable amount of an asset is divided by its estimated useful life.

The quotient is the depreciation expense for each year.  However, if the asset is not used for a full year, the depreciation expense is prorated according to the number of months or days that the asset is in use.

Note that the depreciable amount is the difference between the cost of the asset and its salvage value.

Cost of new machine = $124,000

Purchase date = October 1, 2022

Estimated salvage value = $15,000

Depreciable amount = $109,000 ($124,000 - $15,000)

Estimated useful life = 5 years

Estimated working hours = 10,000 hours

Depreciation method = Straight-line

Annual Depreciation Expense = $21,800 ($109,000/5)

October 1, 2022, to December 31, 2022, = 3 months

Depreciation expense for 2022 = $5,450 ($21,800 x 3/12)

Thus, using the straight-line method, Monty Corp. will record a depreciation expense of $5,450 for the new machine it purchased on October 1, 2022.

Answer: Judy’s mom made 12 sandwiches.
Explanation: 30 divided by 5 is 6. Now we know how much 1/5 is worth. Now you just multiply 6 by 2 because there are 2 fifths.

orderd pair

Answers

Recall that an ordered pair lists the x-coordinate first, then the y-coordinate last: (x, y). So, we know that in one of the pairs, x=-3, and we need to find y. We will plug x=-3 into the equation:

y=4(-3)+6

Following PEMDAS:

y=-6

So, the ordered pair is (-3, -6)

In the second ordered pair, (x, 2), we are given y=2 and need to find x. Input y=2 into the equation:

(2)=4x+6

Solving for X:

-4=4x

-1=x or x=-1

So, the second ordered pair is (-1, 2).


We can check these coordinates via the slope formula as the slope should equal 4 in the equation:

m=(2)-(-6)/(-1)-(-3)

m=8/2

m=4, so our coordinates are correct.

what is the solution of the linear-quadratic system of equations y=x^2+2x-3 y=2x+1

Answers

Answer:

  (x, y) = {(-2, -3), (2, 5)}

You want to solve the system of equations y=x²+2x-3 and y=2x+1.

Solution

The two expressions for y can be equated, and the resulting equation put in standard form.

  x² +2x -3 = 2x +1

  x² -4 = 0 . . . . . . . . . . subtract (2x+1)

  (x -2)(x +2) = 0 . . . . . factor

By using the formula of average speed, it can be inferred that

My average speed is 14 miles per hour

What is average speed?

Speed of an object is the distance covered by the object per unit time

Average speed is calculated by dividing the total distance covered by the total time taken

Length of one block = 560 feet = [tex]\frac{560}{5280}[/tex] miles

Number of blocks = 33

Total distance = [tex]\frac{560}{5280} \times 33\\[/tex]

                        = [tex]\frac{7}{2}[/tex] miles

Total time = 15 minutes = [tex]\frac{15}{60}[/tex] hours = [tex]\frac{1}{4}[/tex] hours

Average speed = [tex]\frac{\frac{7}{2}}{\frac{1}{4}}[/tex] = [tex]\frac{7}{2} \times 4[/tex] = 14 miles per hour

3x - 2 (2.3x + 2.5) = -1.6x -5

5 - 3 (-1.6x - 2.1) = 4.8x - 1.3

Answers

3x - 2 (2.3x + 2.5)  = -1.6x-5 are equivalent expressions while 5 - 3 (-1.6x - 2.1) = 4.8x - 1.3 are not equivalent expressions

How to determine if the linear expressions are equivalent?

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we substitute the same value(s) for the variable(s)

Given: 3x - 2 (2.3x + 2.5) = -1.6x -5 and 5 - 3 (-1.6x - 2.1) = 4.8x - 1.3

For 3x - 2 (2.3x + 2.5):

First, clear the parenthesis by using -2 to multiply what's in the parenthesis. Then add/subtract like terms:    

3x - 2 (2.3x + 2.5) =  3x-4.6x- 5 = -1.6x-5          

                   

For 5 - 3 (-1.6x - 2.1) = 4.8x - 1.3:

First, clear the parenthesis by using -3 to multiply what's in the parenthesis. Then add/subtract like terms:  

5 - 3 (-1.6x - 2.1) = 5 + 4.8x + 6.3  = 4.8x + 11.3

Since 3x - 2 (2.3x + 2.5) is equal to  -1.6x-5 and  5 - 3 (-1.6x - 2.1) is not equal to 4.8x - 1.3.

Therefore, 3x - 2 (2.3x + 2.5)  = -1.6x-5 are equivalent expressions and 5 - 3 (-1.6x - 2.1) = 4.8x - 1.3 are not equivalent expressions

Answer A ; 4934 is the P-intercept. which indicates that 4934 people called Minnesota home in 2000.

Answer B ;  T-intercept is -4934/37, or approximately -133. This indicates that Minnesota had a population of 2000–133 in 1867.

Answer A : P=37t+4934 can be used to represent Minnesota's population in thousands over the t years after 2000.

P-intercept is the P value at time t=0.

P=37*0+4934\sP=0+4934\sP=4934

So, 4934 is the P-intercept. which indicates that 4934 people called Minnesota home in 2000.

Answer (B) : The term "t-intercept" refers to the value of the function t when P=0 0=37t+4934 -4934=37t divide by 37 -4934/37=t -133.351351351 = t

Hence T-intercept is -4934/37, or approximately -133. This indicates that Minnesota had a population of 2000–133 in 1867.

P=37t+4934 P-intercept means the value of P at t=0 P=37*0+4934 P=0+4934 P=4934

Given that Minnesota's population in thousands, t years since 2000, it can be expressed by the equation:

When two quantities are in direct proportion, if we increase one value, then the other will also increase, and if we decrease one value then the other value will also decrease.

Here we have  

x -    1     2    3     4      5

y -  -2    4    10    16     ?      

As we see the value of x is directly proportional to y  

For every 1 unit value of x, the y value is increasing 6 units

For more Understand observe the following

at x = 1  => y = -2

at x = 2 => y = -2 + 6 = 4  

at x = 3 => y = -2 + 2(6) = 10

Therefore,

Write an expression that has only one term and is equivalent to the expression below (f × g²) + 5 - (g² × f)

Answers

The expression that is equivalent to (f × g²) + 5 - (g² × f) is 5

How to determine the equivalent expression?

The expression whose equivalence is to be determined is given as

(f × g²) + 5 - (g² × f)

To start with, we need to remove the brackets in the expression

So, we have the following representation

(f × g²) + 5 - (g² × f) = f × g² + 5 - g² × f

Evaluate the products

This gives

(f × g²) + 5 - (g² × f) = fg² + 5 - fg²

Next, we collect the like terms

So, we have

(f × g²) + 5 - (g² × f) = fg²  - fg² + 5

Lastly, we evaluate the like terms

So, we have

(f × g²) + 5 - (g² × f) = 5

The above expression cannot  be further simplified

Hence, the equivalent expression is 5

The rate of change of the linear functions given in tabular form and equations are found as follows;

1. a. The rate of change of the function is 5

b. The rate of change of the function is 7

c. The rate of then function is 0.75

d. The function has a rate of change of -8

2. The rate of change of the function of -4, indicates that each unit increase in the input value results in 4 unit decrease in the output values

b. The number of days it took for the patients blood sample to have 360 antibodies is 13 days

c. The rate of change of the function is 20, which indicates that the antibody in the patients blood is increasing at a rate of 20 antibodies each day

What is the rate of change of a function?

The rate of change of a function is a measure of how much the output changes per unit change in the input.

1. The rate of change of the functions are as follows;

a. The first difference of the y-values is constant, therefore the function is a linear function

The formula for the rate of change of the linear function is presented as follows;

[tex]m = \dfrac{y_2-y_1}{x_2 - x_1}[/tex]

The rate of change of the function is therefore;

[tex]\dfrac{\Delta y}{\Delta x} = \dfrac{-3 - (-8)}{1 - 0} = 5[/tex]

b. The first difference is constant and equal to 7, the rate of change of the straight line function is therefore;

[tex]\dfrac{\Delta y}{\Delta x} = \dfrac{49-42}{1-0} = 7[/tex]

The rate of change of the function is 7 unit changes in the y-value per unit change in the x-values

c. The function is a linear function, as the first difference is constant and equal to 0.75

The rate of change of the function is therefore;

[tex]\dfrac{\Delta y}{\Delta x} = \dfrac{2.25-1.5}{-4-(-5))} = 0.75[/tex]

The rate of change of the function is 0.75

d. The first difference is constant and equal to -8

The rate of change of the straight line function is therefore;

[tex]\dfrac{\Delta y}{\Delta x} = \dfrac{5 - 13}{1 - 0} = -8[/tex]

The rate of change of the function is -8

2. a. The rate of change of the function, y = -4·x + 1 is found by taking the slope of the function

The function is the equation of a straight line, of the form, y = m·x + c with the slope, m = -4

The rate of change of the function is -4, such that for each unit increase in the input value, the output value decreases by 4 units

b. When the number of antibodies is 360, we have;

360 = 20·d + 100

20·d = 360 - 100 = 260

d = 260 ÷ 20 = 13

It would take 13 days for the patients blood to have 360 antibodies

c. The rate of change of the function means that the number of antibodies the drug produces in the patients body each day is 20 antibodies.

3. The function that gives the amount of antibodies in the body is a = 20·d + 100

d = The number of days

a = The number of antibodies

a. The table is completed as follows;
