Answer:

5 days

Step-by-step explanation:

Given: bacteria to increase from 2000 to  50,000

To find: Number of days that a culture of bacteria will take to increase from 2000 to  50,000

Solution:

The growth of bacteria is represented by the equation: [tex]P(t)=P_0e^{kt}[/tex]

Here, t denotes time, k denotes growth rate and [tex]P_0[/tex] denotes initial population of bacteria.

Take [tex]P_0=2000[/tex], [tex]P(t)=50000[/tex] and [tex]k=0.657[/tex]

[tex]50000=2000e^{0.657t}\\\frac{50000}{2000}=e^{0.657t}\\25=e^{0.657t}\\0.657t=\ln 25\\t=\frac{\ln 25}{0.657}=4.9\approx 5\,\,days[/tex]

Answer:

Since, company A charge of $423.5 is less than company B charge of $450

Hence,

Company A should be hired to get the better deal.

Step-by-step explanation:

Dimension of room: 11 * 14 foot

Area of rectangle is given by length * width

Thus,

area of room using above formula = 11*14 square foot = 154 square foot

For company A

charge  for 1 square foot = $2.75

Charge for room = charge  for 1 square foot * area of room

                           = 2.75 * 154 = 423.5

Thus, Total money charged by company  A as calculated above is $423.5

Given,

company B charges $450 per room

Since, company A charge of $423.5 is less than company B charge of $450

Hence,

Company A should be hired to get the better deal.

Answer:

Company B

Answer:

equation for the new circle is;

(x - 8)² + y² = 36

Step-by-step explanation:

There are two types of translations and they are translation horizontally and vertically. Combining both of them in the context of this question, to translate a circle 6 units to the right and 4 units up, we take our equation,

(x - 2)² + (y + 4)² = 36 and subtract 6 from the x - term and 4 from the y - term to get the equation of the new circle.

This gives us;

(x - 2 - 6)² + (y + 4 - 4)² = 36

This gives;

(x - 8)² + y² = 36

Answer:

8, 18 and 36 respectively.

sum=54

1st number=x

2nd number=x+10

3rd number =2(x+10)=2x+20

x+x+10+2x+20=54

put the liketerms together

x+x+2x=54-10-20

4x=24

divide both sides by 4 to get

x=8

Input the other values

Answer:

The answer is C; y=x+2

Step-by-step explanation:

y=mx+b (3, 5)

5=1(3)+b

5=3+b

subtract 3 from both sides of the equation

2=b

equation; y=mx+b

                y=x+2

Answer:

C. y = x + 2

Step-by-step explanation:

→You can figure this out by using the point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-5=1(x-3)[/tex]

→Distribute the 1 to (x - 3):

y - 5 = x - 3

→Add 5 to both sides:

y = x + 2

Answer:

EF = 34, FG = 25

Step-by-step explanation:

EG is the total of the two smaller segments, EF and FG.

Therefore:

8x-14 + 4x+1 = EG

8x-14 + 4x+1 = 59

Now we can solve this equation.

8x-14 + 4x+1 = 59

12x-13 = 59

12x = 72

x = 6

Now, we can plug in the values of x into the expressions for the lengths of EF and FG:

EF

8x-14

8(6)-14

48-14

= 34

FG

4x+1

4(6)+1

24+1

= 25

Answer:

B

Step-by-step explanation:

its B because the input for every pair has the same output, if the input had different outputs it would be considered not a function. Imagine it like a vending machine, if you were to press 3 on the vending machine you would get whatever 3 was, but if you pressed 3 and you get something else besides whatever 3 is it would be broken. I hope this was helpful, I struggled learning this stuff but now I got it down lol.

Answer:

2 adults and 2 senior citizens.

Step-by-step explanation:

There are 8 children, which means we need to take the number that represents the children from the graph which is 4 and multiply it by the 8 children going.

1. 4x8=32

So we have found the total for the 8 children, however there are 4 spots left

We take the total from the #1 and add 2 adults and 2 senior citizens.

32+6+6+3+3=50

We then come to the conclusion of 2 adults and 2 seniors.

7 years later she will be 4(n - 1)  + 1 + 7 = 4n - 4 + 8 = 4n + 4

Answer:

Step-by-step explanation:

(2, 3) and (5, 6) are the endpoints of a line segment that is not parallel to either axis and does not intersect either axis.

An ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of (x, y). The first number corresponds to the x-coordinate and the second to the y coordinate.

A line segment is a piece or a part of line having two end points.

Since, a line segment is parallel to the either one axis if its one coordinate point is zero, whether it's y or x.

So for not parallel to either axis and does not intersect either axis  we will choose those points which are not zero.

Therefore,

The coordinates of the end points of a line segment that is not parallel to either axis and does not intersect either axis will be (2, 3) and (5, 6).

Similarly, you can use any point using this concept like (7,9) ad (2,3) and many.

Answer:

The ball will hit the ground at 0.968 seconds.

Step-by-step explanation:

Please refer to the attached graph in the answer area.

The given equation of height according to input variable time 't' is:

[tex]h = - 16 t^{2} + 15 ...... (1)[/tex]

h is in feet

t is in seconds

Both the values 't' and 'h' will be positive. (Time and height can never be negative)

To determine the time, at which the ball hits the ground, i.e. the height becomes 0.

Putting value of h = 0 in equation (1)

[tex]0 = - 16 t^{2} + 15 \\\Rightarrow t^{2} = \dfrac{15}{16}\\\Rightarrow t = \sqrt{\dfrac{15}{16}}\\\Rightarrow t = 0.968\ sec[/tex]

Hence, the time at which the ball hits the ground is 0.968 seconds.

Answer:

1 39/50 hours. This is equivalent to 1.78 hours.

Step-by-step explanation:

The sum of the hours of work and the hours for break gives the work day hour which has been given as 8 hours.

Furthermore, given that the break time is 22 1/4%, the number of hours for break

= 22 1/4% × 8 hours

= 89/400 × 8

= 1 39/50 hours

Answer:

A = 100π units²

Step-by-step explanation:

To answer this we first find the circumference C = 2πr, and then multiply this C by the height:

C = 2πr, or C = πd.  Here, C = π(10 units).

Then the lateral area of the cylinder is A = C*(10 units), or

A = 10π(10) units², or

A = 100π units²

The lateral surface area of the given right cylinder is 314 square units.

The lateral surface area of a right cylinder is the product of the circumference of the base and the height of the cylinder.

Given, the base diameter(d) of the cylinder is 10 units.

Therefore, the base radius(r) of the cylinder is

[tex]= \frac{10}{2} units\\= 5 units[/tex]

The height(h) of the cylinder is 10 units.

Therefore, the lateral surface area of the cylinder is

= 2πrh square units

[tex]= 2(3.14)(5)(10)[/tex] square units

[tex]= 314[/tex] square units
